I own an Optima Horizon condo in downtown Evanston. I was very disappointed with the heating/AC company that I had been using for 16 years. I had done research and calling different companies who maintain and repair the special units in all Optima buildings. When the heat stopped working in the beginning of January during a below zero weekend, I knew who I was going to call first thing Monday morning---- Del-Jo. They gave me an appointment that same day and said they would be there after 6 pm. The technician, Jordan, arrived at 4:30 pm. He had 10 years experience and checked the unit out and was able to jerryrig it to work until the part was in. Their prices are fair and have maintenance plans with discounts. I highly recommend this responsive, knowledgeable and custom friendly company. read more

Kevin and crew were amazing! Respectful and kind! AC rocks!!!! So happy with service and cost! Quick to respond at a very hot time..

Tech tells me cleaning my unit was going to stop my furnace from shutting down. Quoted me $2,200. Blown away by the price but below zero temps so they take advantage knowing there's no choice. I asked if 100% sure that would fix my issue as I do not want to pay all that for nothing. I was told YES. after the cleaning I am told "well looks like the issue might be something else"!!! Tech tells me he will call his boss to see if he can reduce the cost since he was wrong. Of course his greedy boss doesn't back up what his own tech guaranteed and says no. Here am below zero temps, $2,200 down the drain and freezing with kids in the house. It's disgusting how these clowns just steal by lying. Their justification was "well your unit was going to need the cleaning eventually anyway". I NEED HEAT NOW NOT WORRIED ABOUT EVENTUALLY!! Update. New HVAC company fixed my furnace today within 30 min. All I needed was a $90 dampener. My unit is working perfect now. Service I received yesterday was not needed and what I was told was untrue. my heat exchanger wasn't fully cleaned yesterday even though 1150 of the 2200 I paid was for that. I had it checked. The written recommendation to have my unit replaced I was told is ridiculous. My unit was built in 2018. All excuses given to me by Deljo were after they charged me 2200. Had they said it before their "guarantee" I would have declined service. read more

This review pertains to work done several years ago, but the experience still irks me. I have since switched to a different HVAC vendor. First Appointment: Technician #1 came to my home to evaluate an AC problem, said the refrigerant was low and told me to schedule another appointment. Second Appointment: Technician #2 insisted the problem was not the refrigerant and upsold me ductwork cleaning for $795. This did not fix the AC problem. Third Appointment: Technician #3 informed me that Technician #2 "misdiagnosed" the problem and supposedly was being "reprimanded." Technician #3 added refrigerant, which solved the problem. read more

Deljo installed a replacement high velocity air conditioning system in our older home. The work completed did not meet the terms of the contract, which included re-insulation of exterior lines to our compressor. The installation crew reinsulated less than a foot of our line. The crew also did not tune the fan speed. They did not read the pressure from any of the high velocity outlets. In some rooms, the unit sounds like a jet engine. The crew instructed us to contact sales for follow up. The salesperson has been unresponsive to email. read more

I recommend DELJO because my boiler was not working on the coldest of winter nights and they actually responded to my emergency call right away. Let's face it, a night without heat with -20 windchills...I do not want to even think of what it can do to the pipes in the house besides ME. I called 9 places prior to them and no response. I was so happy that David C called me in about 15 minutes and would come, of course, for an emergency service call fee. He came and I could feel he was so honest, caring, wanting to help and I felt God sent him to me that cold night. It was GREAT!m Thank you DELJO and may all your repair men be just like him! I finally found a company I can trust! read more

Terrible company. Terrible service. We had the Deljo "gold star" maintenance program for years. Some clown would come out twice yearly to supposedly clean everything. When one of our a/c units froze up, we were told by one of their own other more experienced service guys that it malfunctioned because it had never been cleaned. Unfortunately this came about after they had already overcharged us thousands of dollars to replace the unit. We were having an event at our home and were desperate to get it working asap. The father and son team of con artists are pathetic, dishonest scammers. We had previous similar occasions such as when they wanted to replace a wine cellar unit for $8000. We had someone else come look and he fixed it for free. read more

I woke up on the coldest day of the year, only to find my furnace had stopped working. I called Deljo and they sent someone out that same day. David C. figured out the problem and fixed it in no time. Very impressed with his professionalism, knowledge and service! read more

What a mess of a company this has become. It's such a shame that they went and also purchased American Home Heating/Cooling a few years ago and mangled that nice little business too. The Deljo answer to every problem seems to be "there is no way to repair, must replace". Multiple times now I have spent money on techs that come to my home unprepared and unmotivated to attempt to fix furnaces, condensers and now a hot water heater. No more. Done with Deljo. Hot water heater still leaks, they didn't attempt to plug a leak or any type of remedial action- instead only offered a $6100 replacement unit. Picked up the same tank, installed for $2600 elsewhere. Deljo, people just aren't as clueless as you want to think they are. Good luck to you guys. read more

June 23, 2022 central AC service call; This is the 3rd year that we have had our condo unit serviced by Deljo. 1. Pre-appointment communication = excellent 2. Service Tech competence = very good 3. Fixed cost for a basic AC maintenance call ($137) = reasonable 4. Cost for refrigerant recharge, dye/sealer and labor ($1,140) = predatory! The refrigerant was $243 and the dye/sealer kit $524. The exact same dye/sealant kit can be purchased for $50. I emailed my dissatisfaction only to receive a reply admitting that their charges are, in fact, high. This is mainly due to the quality of their work and the overhead they need to account for. BEWARE $$$ before hiring this Vendor! read more

These people are completely criminal. I had one of their techs out today to provide a quote for a repair on a Navien tankless hot water heater. They quoted me $3080 to $3624 (a brand new unit is $1500 from Navien), I called Navien to get the part numbers needed. I ended up ordering the parts for $302 with two-day shipping. It wouldn't take more than an hour or two to replace the parts that are being shipped based on a conversation with Navien. I have recommended that Navien remove them as a service provider on their website as it makes them look horrible. They clearly are inflating prices to encourage/force people to buy new units. read more

Ask for rates when you call. I was charged $149.36 for the same part that can be bought online for $15.00; and $294.64 for the .53 hours of service to install that part. read more

Good service, very professional. Overpriced by a couple of hundred dollars $$ for a routine service call. If they lowered their price to match the market, I would use them for all my service calls and recommend to others. Would use in a pinch if I can't get anyone else to come out when needed, otherwise can find same service for much lower price. read more

I had them for a while because I thought that I will have fewer maintenance calls and fewer issues if I pay monthly and have '' professionals''. After a while below is discovered. 1. They always try to sell you something additionally, which I bought from the hem, but then it became a routine for their tech guys to push something you do not need. Latest was the water sensor under the HVAC for $150 each. Security system companies sell the same things for $30.00. 2. I have a really sophisticated system, though they can deal with it, well not that easy. their tech guys were at my place at some point for a week. 3. The issues when they come up, they kept coming back. I finally decided to cancel and guess what, I have to pay up an additional 3 months because I had they come and clean the system 2 times. So the membership gets you the fact that someone will come to you when you need for $1200 per year membership if you calculate the fact that you would have to stick with them for a year after they come over for maintenance cleaning. the last drop was when the air cleaning system that they installed and is under warranty broke. Just front panel had to be replaced. The company told that they would replace it for $130 for a visit. My question was why do I have to pay if it is under warranty? Well, the panel is under warranty, but their visit is not free. I asked for the item to be shipped to my address so I can just plug in the cord, literally. Their manager refused to do it because it was bought through them. I just went to a different HVAC company and asked if they can order an item that is under warranty, they said yes. read more

Do not hire these people. Absolutely devoid of decent morals. I've purchased three furnaces and three ac units from this company. I've given them thousands upon thousands of dollars worth of business. So i thought maybe they would be helpful if something we're to go wrong with one their products. Boy was I wrong. First it was 100 bucks just to come have a look it. A little high for a service call but hey, they sold the product so they should be able to fix it with some efficiency. The guy tells me the motor is out. And it would cost $775.00 to replace it. That $775 is just for labor! The part is actually free because it's under warranty! So I ask how long will it take for you to install it? He says 1 hour! $775 for 1 hour of labor?! $775! And here's the kicker! That initial $100 doesn't go towards the $775 if you unfortunate enough to fall for their scam! So it comes to around 1000 to install a free part that take about an hour! I'm convinced it's all just a scam to collect that initial $100. It's pretty obvious these guys are taking advantage of the cold weather. It's just absolutely lunacy. I thought price gouging was illegal. I'll be sure to check with the better business bureau. This company is morally bankrupt. I'll never buy a product from them or use their service again. Unless my infant daughter needs emergency heart surgery. Maybe then I'll get some bang for my buck. At a hourly rate like that, they should no doubt be turning water into wine. read more

This is the second time I've recently called Deljo and it will be my last. My most recent experience made it clear that their main interest is to sell unnecessary equipment and services at the cost of thousands of dollars, as opposed to providing real solutions or investigating root causes. I scheduled a call for regular maintenance on two gas furnaces. One of my furnaces had two clear issues. When I asked the onsite tech how what he was selling me (a membership to an annual maintenance plan, external water sensors and routine cleanings of the A-coils and blowers) would help the issues he pointed out (clicking noise coming from the inducer motor and an overheating/airflow error code), he said he didn't know that they would. He never even proposed a solution for investigating the clicking noise and cleaning out the debris in the inducer, which was making a loud noise that he himself was able to reproduce! How do I know all these fancy terms and specifics? I joined a HVAC FB group and the professionals there were more helpful than Deljo. They were able to identify the issues over a video and provide possible causes and solutions (for free!) that fixed both problems. The only reason I'm giving Deljo one star instead of zero is because the technician, who was young and looked like he was just starting out, was respectful and courteous. He was actively communicating with his "boss" via telephone throughout all of this so, at the end of the day, his service and solutions were vetted. I was really hoping that Deljo would continue the great service provided by American Heating and Cooling, which Deljo purchased during the pandemic, but it's time to find a new HVAC provider. read more

One of the best companies I've used for furnace cleaning and tune-up. They came on time, they were professional, they did incredible work, everything works amazing. I would highly recommend their services to anyone who needs heating and cooling! Please disregard all 1 star reviews on their account, they are clearly not well informed of the services and what it takes to do this job. 5/5 star. Thank you Deljo Heating and Cooling! read more

I feel so lucky! After multiple calls to another provider, and no calls back - my husband rang Deljo. While we had not had them service our current home, he recalled how outstanding they were for us 5+ years ago at our former condo. I received a swift follow up call from Tony, who informed me that the evening was packed and that the likelihood of a technician being able to visit us tonight was extremely doubtful. He took a moment to ask if it could wait until morning, but more specifically he asked for details. In the 10 seconds I spent describing the issue, he asked if I wouldn't mind sending a few photos of the unit to his phone. He thought he may be able to tell if it was a simple fix. And guess what?! He was absolutely right. A simple switch had been tripped by my vacuum getting put away, and it was keeping the furnace off as a safety thing. Problem solved. Thanks to Tony's intuition and empathy - my two young kiddos and I will have a warm house on a night it will be sub 20 outside. Thank you again! read more

I had a leak situation with my furnace & Deljo was not only super responsive but also really thorough. The technician took the time to not only diagnose & fix the problem but he checked /rechecked to make sure the problem was solved. He explained as he went so I always knew what was going on. I was skeptical after a bad experience with another heating & cooling business, but Deljo earned my confidence! read more

Overpriced, felt price gouged Tech came to do a furnace tune up and recommended a few repairs, one was for a capacitor. Quoted $200, which I assumed was a fair price (shame on me). It took 5 minutes to install and I looked up the same make/model of the part online and it costs less than $10. I then got quotes from other competitors and they were all less than $100 for the labor plus part repair. The fix was made appropriately but was almost double the fair market price so recommend shopping around before committing to any repair from Deljo and this experience will influence who I do business with going forward read more

The caveat is that I have never used another company to service my furnace or my air conditioning unit. However, the times I have used Deljo Hearting and cooling I have had a good experience. They recently came to my condo to service my furnace and my air conditioning unit. The scheduling process was easy and fast, and they were accommodating on the date and time I needed. I schedule my appointment at 8:00 am, which was a big help. They came pretty much on time with the technician arriving at 8:15 am. My technician was Alan. Alan spent about a total of three and a half hours at my place. When he was done with each inspection he provided me with a non-technical explanation of everything, and made it easy to understand. He was also willing to answer all my questions, and he was very friendly. I also appreciate that he wore plastic covered slippers while inside my house as I have recently redone my floors. The total change for the service of the furnace and my air conditioning unit was $239.00. Like I said l, I don't have a frame of reference from other places, but for the time spent, and from what he did I'm told this is a decent value and inline with what other places charge in Chicago. Of course, he gave me a laundry list of things I could spend more on, and even suggested I should look into a whole new system, but I feel that's expected. read more

If I could give this company 7 stars I would! These guys really go that extra mile and everybody that I have dealt with were super professional and super friendly!! I have dealt with many other HVAC companies that have the personality of a salt water crocodile but these guys are share the passion of putting customers first!! I especially appreciated how they were so honest and while I was anxious to get rid of my old heater and get a new one, after inspecting it they told me mine unit still had plenty of life and all it needed was a tune up. Still not convinced, I really wanted them to sell me a new one but they really sat me down and gave me very good advice and ended up agreeing with them. I definitely recommend Deljo Heating and truly appreciate their integrity and honesty. I told them however, that by next year I will want a new one regardless they laughed!! (By the way, I found these guys as I jog on the Skokie Trail that goes from Dempster ave in Skokie down to their location and each time I run, they were so kind enough to allow me to get access to their drinking fountain.) read more

This is the second major project we have used Deljo for in the past 4 years. They previously replaced our basement boiler for radiant heat a few years ago when the old one failed during the first winter after buying our house. This year we brought them out for a quote followed by installation of a ductless mini split AC system on the first two levels of our home. Just as the last time, the entire process was smooth from start to finish. First, advisor Ryan came out to assess, talk with us about our goals, and present the options and costs which was very educational and thorough. Once we decided what to do, project manager Brian and his crew came out the following week to start the install. Due to covid, my partner and I are working from home and the disruption to our daily routine was absolutely as minimal as could be. The team was very clean, efficient, and aesthetically did everything they could to make the required exterior lines and internal ductwork look like it always belonged in the space. We've had the system for over a week and thanks to some early fall heat and moisture have had a few days to test the system out. We went from 3 standing AC units + 1 large window unit to 4 wall mounted ductless units + 1 unit in the basement that vents up through the floors of two different rooms. The difference is night and day from our prior setup. Not only have we reclaimed floor and window space, but the cooling and efficiency is clearly better than before and the system is SO quiet (maybe the biggest win!). I would highly recommend this type of setup for those with older houses that aren't in a good position to run ductwork all over the place. And it almost goes without saying that I highly recommend Deljo for the job. They surely aren't the cheapest option out there- but when it comes to major HVAC work like this you're going to get what you pay for. Deljo certainly delivers when it comes to these types of projects. Highly recommend! read more

Matt serviced my AC and was kind, courteous, and expedient. Deljo customer service was also highly communicative and sent out help quickly, as well as courtesy reminders via text. read more

Deljo was the second team company I got a quote from for my furnace replacement, and I'm so glad I did! Ryan was thorough and explained all my options when he did the inspection for a quote. Unlike the other company, Deljo gave me options from the top of the line to economy options, which I appreciate, without trying to oversell me on more than I needed. Wesly and Dave did a great job on the install. There was some special fitting needed for a drainage pipe, and they took the time and care to come up with a solution that didn't require additional pieces or add cost. My new furnace is working great and so much quieter than the 25 year old beast I replaced! read more

I recently purchased a new AC and furnace from Deljo to replace an 18-year old system after the furnace inducer assembly locked up. Figured it was time to bite the bullet and start fresh. Matt Barbosa came over to assess the situation and explain my options for a new system. He was very thorough in his explanations and was able to work with me on a price that I was fairly comfortable paying. Great service there. I also have to highly commend the service techs who came to install the new units. They were fantastic. There was a lot of work to be done (had to remove my water heater to access the furnace and then replace it after completing the install), and they finished it off in 7 hours! They were also very pleasant throughout. Highly recommended! read more

The crew at Deljo are awesome! They recently installed a Carrier air conditioner and furnace system at our condo. The entire staff from maintenance, to sales, to the installers were very knowledgeable and thoughtful individuals! I would highly recommend Deljo. read more

Some of the most inconsistent support I've ever experienced. The latest situation happened this past Saturday. I had water dripping from where the AC unit was. Called to send a tech out and customer service said they'll fix the leak first. The tech arrived - didn't even introduce himself - and was moving slow given water was coming from the ceiling. He eventually went down to get a ladder, came up, tore away the insulation on the pipe which caused water to come free flowing out of my ceiling. He could not figure out how to turn the water supply off and it was a rainstorm in my bathroom for almost an hour. It wasn't just water - it was freon (which has 30% anti-freeze). So it was an absolute mess to clean up. Once the water was shut off (after we called in my main maintenance man who was supposed to be off that day) and things were cleaned up, I asked the tech for the solution. And he said "actually we don't work on these types of systems"....What the heck! Why did he even touch it to begin with? It was just awful and frustrating and I'll never be using them again. The best part: when I called this AM, I told the support team "I had a terrible experience with one of your techs on Saturday and will no longer be using your services". Her response? "Oh sorry about that. Have a nice day", Good riddance. Now to find a new HVAC company who will tell the truth. read more

I've been a Deljo customer for close to 30 years, and at one point they certainly deserved a great reputation. I think most of their techs probably still do. But I don't believe management cares about customer service any more. Four years ago I bought a top of the line furnace, air conditioner and thermostat from Deljo. Since then I've had multiple issues and service calls. I have a gold star maintenance plan. On Wednesday afternoon I called to tell the service tech that the air conditioner was running without stop, and that the thermostat indicated it was 75 degrees in the room, although it was only 69 degrees. The tech told me that I would need to wait five days, until Monday, to get service because she did not have a 40 foot ladder available. I'm in my 70's, its going to be 91 and 93 for the next two days, and they can't get out to me for five days. So much for their top of the line equipment, gold star maintenance plan and supposedly top of the line reputation. read more

We have radiant heat flooring in our basement, in addition to HVAC in the rest of our home, so it's not an "essential" heating system. Something in the radiant heat boiler was making a loud whining noise and we had another company come out and were quoted about $16,000-$20,000 to replace the boiler and its water pump. True, the boiler is old and out of warranty. But $20K? We called Deljo to get a second opinion. Their technician, Charlie, was awesome. He diagnosed the issue as solely the water pump, which he replaced within two hours. The final charge? $896. That's not to say we won't have to replace the boiler in the future, maybe even soon, but as I said, it's not our sole source of heat (though it does make the basement a nice, toasty and more livable part of the house in winter.) And it sure felt better to replace one small part (the other company quoted us $2000 for the water pump) than to spend all that money up front right now. We couldn't be more thrilled with Deljo! read more

Very professional and was extremely friendly.....Knew his job and explained everything from the start of the A.C. inspection. Answered my questions and was able to complete the A.C. tune -up to my personal satisfaction. Very pleased with the price too ....Will definitely have Deljo out again next Spring!!!.....THANKS !!! read more

I am writing this review because I am livid! I called today to have a boiler checked before it gets too cold. It was purchased in 2020 with Deljo, and it wasn't cheap! now I am told they no longer service my area. They didn't tell me this when they took my check! I guess chicagoland, IL as stated on their website is not close enough. The real reason is because it's on the west side of Chicago and not a preferred area. Don't spend your money with people who don't support their product! I am by no means done but I had to put this out there. Prior company used American Home Heating was purchased by this firm and we never had an issue. Our money is green just like everyone else's. I never do reviews but they are on blast today. read more

Was not aware they took over a company I had service done before. Bought a hot water boiler from that company.. Have a slight leak from a pipe coming from boiler. Called because I figured the boiler would need to be drained so the pipe could be replaced and would prefer it be done by heating experts. Called for an appointment told they do not do plumbing,, call a plumber. Told that I could make an appointment for them to drain the boiler. What kind of heating company restricts their work to the boiler itself, but you have to call a second plumber for any of the pipes leading to and from the boiler? Curious how they install boilers without the ability to do any plumbing. In business since 1921 WOW! read more

The definition of shady business dealing in Chicago. Person was supposed to be out between 9-1 on a Saturday. At 1 PM I called to find out where the person was. Person shows up at my condo around 4 PM. Turns out that suddenly my whole HVAC unit needed to be replaced. When I ask for quotes, it's next day, but suddenly the quoted price of coming out more than doubled. Lot of shady HVAC people in Chicago. Beware!! read more

Your technician showed up on time, wore a mask, explained everything he was going to do, completed all the checks, and gave us recommendations for improvements we could make. All was done quickly and efficiently. Good job! read more

Do not use these bozos to have your HVAC installed or serviced. They installed a furnace in a condo I bought in 2019 (furnace was installed in 2016) and they totally f'ed up the air filter vent installation. See the attached photos for the ugly details. It cost me 3K to get their "handywork" fixed. On top of that, the humidifier housing they installed was cracked leading to water leaks. They also didn't run a code compliant drainage line for the A/C humidifier either. When contacted about this, they refused to take responsibility for their handywork. DO NOT USE THEM. read more

Had AC lines that were freezing up so we called American Home Heating and Air that we have used for the past 15 years to send someone out. My wife handled setting up the appointment and I guess this place bought American's phone number when they closed up shop because they were the ones that showed up to look at the unit. Well we were quoted $375 to replace a capacitor (which runs about $8 on Amazon and is secured by 2 screws and 2 quick connect wires) and $708 to clean the blower fan motor. No breakdown of labor, parts, time etc...just a number. It was also suggested that we speak to a 'comfort specialist' about replacing our entire system as it was 'old'. Obviously we went a different direction. Another company comes out takes 5 minutes to figure out the blower motor has some electrical issue and is running too slowly therefore not moving enough air and needs to be replaced. 60 minutes later the motor and mounting bracket are replaced the system is recharged and everything is once again running great. Cost us $380 for new motor, mount, capacitor and system recharge. To be fair, the gentleman that made the service call from Deljo was extremely professional, neat, kind, punctual and well spoken. He was upfront about the costs as well but didn't really have any answers for why the prices quoted were so high. We paid the fee for the service visit and let him know we would not be moving forward with them. There are far better options available in this trade space. Look for the guys with several hundred 5 stars Yelp reviews instead of this 3.5 star company. You'll save yourself a lot of money. **I live in Chicago, IL. Don't know why it says San Fran on the review? read more

I had an A/C unit installed on 6_5_2020. I had been a loyal customer of American Home Heating for years. I had a service contract with American Home Heating which Deljo honored. My Central Air failed on the first hot day, prompting my call to Deljo. Had a bit of a phone wait, to be expected on the first day we all turned on Air, but it was reasonable. Service was prompt. Discovered my 18 year old condenser had given up. Next, my salesman Jim came, was very professional, and we negotiated new unit. Discovered my old unit too big for my house, went with a 2.5 ton Carrier. Jim's explanation of my needs, and the reason why, were clear and precise. Price was a bit high, in my opinion, but Carrier carries a premium, and it was the peak of heating season, and I did not want to mess around. 1 week for delivery and installation, not bad considering. Installation was done by Carlos and Chris in a very prompt and professional manner. They left my house spotless. They wore masks and were careful to social distance. They were courteous and attentive to my questions. I will sign-up for their maintenance plan, and use them for new furnace, down the road. read more

We were having problems with our A/C. The coil kept freezing up. We called Deljo, waited several days for a tech to come out. He said there likely was a clog in the TXV. We could replace the TXV for almost $3,000 or get a new coil for almost $4,400 dollars. Given the expense we asked for a quote on a new condenser and coil. Salesperson came out the next day. He said he couldn't comment on the repair quote. So I called Deljo and the woman on the phone said the tech would call me back to explain. He never did. The salesperson quoted almost $7,800 for a new condenser and coil. I grew up in the HVAC business and that seemed asinine. I poked around on Yelp and found a different outfit that was highly rated. I sent them photos of the units and ductwork. They quoted $4,600 for a new condenser and coil. That seemed much more reasonable. They installed it the next day. It's working great. If you do get a quote from Deljo - make sure to get a second opinion, even if it's just over the phone. read more

So my 17 yr old furnace started doing bad things... I have a gold star program with Deljo and they came to the rescue.
