As a new homeowner, I have been trying to stay on top of regular maintenance, and I had quite a few questions about my HVAC system. My brother recommended this company, and I'm really glad I decided to give them a try. From the start, they were honest and helpful. I initially reached out about my AC, and instead of rushing out for an unnecessary visit, they suggested waiting until the weather warmed up so we could properly test the system. I appreciated that thoughtful approach. I stayed in touch with them, and we eventually scheduled a Saturday appointment to fit my availability. They showed up as planned, inspected everything thoroughly, and found no issues. What stood out most was that they did not try to upsell me on anything--just straightforward, professional service! I am already planning to have them check my furnace in the fall, and I wouldn't hesitate to recommend them to family and friends. read more

Highly recommend A Climate Source. Spyros and his team have fixed my old AC when it broke, replaced my AC and furnace and come back for regular service/repairs. Spyros is super responsive and he and his team are extremely respectful, knowledgeable, and fair. I'll be coming back to A Climate Source for all my HVAC needs. read more

My air conditioning wasn't working, Spyros sent Tony the next day and he had it fixed within 20 minutes, He was very friendly and professional! Thank you for a great experience at a reasonable price. I will definitely be using A Climate Source again!! read more

I've been absolutely blessed with EXCELLENT H.V.A.C. service through A-Climate-Source for a number of years. The owner, Spiro, is truly wonderful, both professionally and personally. Spiro's SO knowledgeable within his profession, and he always provides excellent customer service!!! read more

I am impressed with the ease of scheduling, phone call on the day of service to announce timing of arrival, professionalism, excellent service, suggestion on timing to change furnace air filter, and overall efficiency. Highly recommend Tony at A Climate Source. read more

Our family has been doing business with Spiros for years, and I strongly recommend his team to family and friends. Fast, responsive, reliable, and fair. From annual furnace and AC inspections to complete HVAC replacement (as we're doing right now), Spiros goes out of his way to make sure that we're always informed and satisfied. We trust them 100%. Worth noting that Spiros's brother Paul is also an appliance expert, and has always been there for us when we need help with our oven, stove top, washer, and dryer. Ultra-fast response. Always fair and professional. Two thumbs up for these gentlemen. read more

Our 17-year old furnace had to be replaced, so I solicited quotes from 4 contractors. At the recommendation of a neighbor, A Climate Source was one of these contractors. I was very pleased with A Climate Source's approach to the project and with the value they offered, and I hired them for the job. The completed the job on time, on budget, and with a professionalism that inspired trust and respect. Spyros and his team are hard-working, skilled technicians who take pride in their work. If you are looking for a competent and dependable HVAC contractor, give them a chance. You won't regret it. read more

We had an issue with our A/C unit and I called A Climate Source based on the high praise for them in the north park neighbors group. They came the same day and resolved our issue. Quick, friendly, knowledgeable service. Reasonable prices. Covid safety measures were taken, masks worn. Easy payment through Zelle. l will call them the next time for sure. read more

Your search for an HVAC company is over. Hire these people. We've had them out several times and they are heroes. Professional, friendly, talented, honest...exactly what you need. read more

Highly professional. Uber friendly on the phone, no matter who I spoke to. I found them as a certified service agent on the Electrolux web site. A solenoid went bad in our 2-y.o. Electrolux washer leaking water all over the laundry room floor. When I called Electrolux they informed me that we were *just* out of warrantee (naturally). They gave me the name of ACS for service. The tech who came out for the service call said this was going to be a pricey repair with parts and labor for two techs and a couple hours. He encouraged me to go back to Electrolux and press for some kind of compensation since it was not a common failure & so close to warrantee. I took his advice and was able to get both the part *and* the labor from Electrolux. (Thank you, Tony!) They've been here twice. Each time I got a call by 8am the morning of the scheduled visit giving me a 2-hour arrival window. The second time they didn't make that window. Not by a long shot. But the tech did call to revise it and met the second window. So ACS gets points for that "communication thing". They followed up twice after the initial service call when I was dealing with Electrolux. Once things were squared away with Electrolux, they called multiple times to keep me informed along the way about parts ordering, delays in the part's arrival, its arrival, and rescheduling the service call. This is what customer service is all about. It's not hard. It's just attention to detail. The initial consultation charge is $65 for the visit. However, they apply that to the final repair costs. Very reasonable, in my book. Top notch and classy, all the way around. read more

Wish I could give this another star . The company I was previously using for a few years came out yesterday as HVAC wasn't blowing cold air. After 20 minutes the guy came down from roof and said my compressor was dead and quoted me very high to replace furnance / AC combo as it's 15+ years and came with the condo when was built. My uncle recommended giving Spiro and a climate source inc. a call to get a second opinion as he has been using them for a long time. Within 24 hours was able to make a trip out to Evanston and within 15 minutes Tony had the HVAC system up and working again where only needed a new capacitor (or a much cheaper part) Tony was very friendly and knowledgeable. I'll definitely look to use this company moving forward as they know what there doing and have serviced my uncle and other family members for many years read more

it's a no-brainer to use Spiros and crew for HVAC needs. simply the best service provider of any kind I have experienced in 30 years in Chicago. professional, straight-forward, responsive. read more

I've had these guys to my condo to fix my heating and my air conditioning. Really can't say enough good things about them - friendly, on time, professional, and great communication. I would confidently recommend them to anyone! read more

We have a Fujitso mini split with heat and ac that was installed by another hvac person last June. The unit kept losing Freon and come winter, the units heating cycle would not work. We had another heating unit so we waited until the weather was nicer to have it fixed but before the summer heat. Tony came out, found the leak and repaired the unit in 3 hours. He showed me pictures and kept me informed throughout his visit. Spiro, the owner, and his team are incredible and you should not hesitate to hire real pros. Excellent service with fair pricing. read more

Seventeen years ago, we purchased a fifty-year-old home with multiple additions that had four furnaces, two air conditioning systems, a spa and one hot water heater. All were good equipment but aging. Several pieces of equipment were mis-sized and otherwise less than expertly installed in makeshift ways. Over years we have lived here, Spyro, of A Climate Source, has kept alive what equipment he could and retrofitted and replaced what he could not. Spyro has improved the HVAC in this house many times over the systems that we initially purchased. Often on an emergency basis, most recently when our doddering main furnace finally died just before the current super-freeze. The old hot water heater, which was making the popping sounds indicating its imminent demise, had been inaccessably located in a corner behind the huge old furnace. Over this past weekend, Spyro removed the huge old furnace (in pieces), and the old water heater, and replaced both. The job was a nightmare that involved refitting the ducts, exhausts and even rebuilding the crumbling concrete floor - all on an emergency schedule because the weather is heading subzero. Spyro is a genuine expert at everything connected with HVAC, a totally honest tradesman, reasonably priced, and an exceptionally caring person. If you are lucky enough to be able to get your HVAC on A Clmate Source's schedule, do not let go of them. You never will find Spyro's equal. read more

We have used Spyros for years to help us keep an older furnace and AC unit going. Well, it finally died and the A Climate Source team came out today and completely replaced the unit. Not only did they NOT have to run wires or pipes outside our ductwork, but everything was done quickly and efficiently, with NO clean up needed by us at all. Tony and his crew got right to work but answered questions and explained what exactly what was being installed. All product information and warranties were left here, Spyros called and said he was going to register the unit for us. These guys are phenomenal. CALL THEM without hesitation. Very professional, prompt and knowledgeable. Every time we had to call before (sometimes when it was blazing hot or freezing cold), they found a way to come out within a day to help us. Cannot recommend highly enough. Thank you A CLIMATE SOURCE!!! Carol and Michael read more

I called Spiro at A Climate Source and he was all you could hope in a service professional. He was out the same day and immediately diagnosed the problem, provided the cost of possible/upcoming scenarios, and braced me for the reality of a new furnace in the very near future. The very next day he and his assistant came out and replaced a problem part easily and, thank goodness for now, I have heat. They were quick, clean, and friendly. Spiro is easy to talk to, good at explanations, and has a sense of humor. Plus, the repair was less that estimated. Well done!!! read more

Spyros was awesome. I had a 125+ pound A/C window unit I needed installed. I was getting quotes as low as $130, but those people wanted me to meet them at Home Depot, help them put it in their "car/van/who knows," and they went as high as $400. Spyros quoted me $190, for two people, picked the A/C unit up at Home Depot, met me at my unit (2nd foor) with another guy, and within 1-1:15 hours, they had the unit installed, extra support added, etc. Extremely professional and I'd honestly recommend them to anyone and/or use them again. I was happy to give a generous tip because, well, they more than deserved it. He said they don't advertise and really only work by word-of-mouth, so here's another suggestion from an extremely HAPPY and PLEASED customer! Thank you so much for the work you did! read more

A Climate Source is an outstanding operation all around and I highly recommend it. I have had all of my heating and cooling needs met, maintained and exceeded by Spyros and his amazing team members Tony and Fernando. These guys are as good as it gets, extremely helpful personable, prompt, knowledgeable and clearly have a great work ethic. I've relied on A Climate Source for around 10 years and will happily continue to do so for another 10+ years! read more

Great work very responsible and professional. They took their time to leave the work perfectly working and in good condition. They did not charge us until it was all good. Happy to had them. Very recomendable. Thanks read more

Got referred to A Climate Source from a friend and was extremely happy with their work. Spyros was very knowledgeable, super friendly, and affordable. He also took the time to explain what was wrong and what he was doing, which really showed me that he cared about what he was doing. I will definitely be calling A Climate Source the next time I have any HVAC issues or upgrades. So glad to have found them! read more

Spryos is great, Fast, efficient, and friendly. Hes always offered me great service and affordable prices. I have recommended him several times and he is reocmmended by our property management company that services our condos. read more

If you're looking for the best in HVAC and appliances service, look no further. I've used A Climate source several times for my heating and A/C issues and also for repairs on some of my major appliances. I came home around 6 and noticed the furnace was blowing cold air. I called ACS and Sryros arrived in less then an hour, took care of the problem by 7:30. To make a long story short, professional, reasonably priced, and most off all, caring. I highly recommend this business read more

Amazing service!! So we recently moved to Chicago and let me tell you it's very hard adjusting to a new city and even harder to get acquainted and find good service companies. My heat stopped working and I asked a neighbor if she knew of a heating company I can use and she recommended I call Spiros with A Climate Source. He answered my call immediately and showed up at the time he said he would arrive. It so happened that my thermostat was bad and he was able to replace it and everything started working. Thank you so much for your excellent service also for being honest and reasonably priced. Will definitely be using them again. read more

Spiros and his team are just the best! Completely efficient and very affordable!!! I have used a climate source at my shop in Bucktown and now just used my climate source for my home AC. I will not go anywhere else. they are the most reliable HVAC company in Chicago with immediate service. I texted around 8 AM and Tony came by at around 10 AM to fix my unit and it took him about 45 minutes. Being eight months pregnant with 100° weather and no AC is no good. This was so quick and hassle free and I know the work will last, thank you Spyros and Tony!!! I cannot say enough good words about this company! read more

I have used A Climate Source several times for heating and air conditioning for my primary home and rental properties, and referred them to clients more often than even using them myself. For years, I had been looking for a reputable, trustworthy and reasonably priced HVAC company for years (literally!), and fortunately found A Climate Source some years back. Without fail they have been easy to work with, let you know when they arrive at your home and actually arrive as scheduled, are friendly and informative, and don't overcharge for their services. As a realtor and landlord, I value having great people to call and refer to others as much or more than most people. A Climate Source does a fantastic job each and every time, and has certainly earned my loyalty! read more

I was lucky to have been referred to Spryo, the owner of A Climate Source, nearly 20 years ago. If you have an emergency, he will take care of you and make you a priority no matter how busy he is. He works tirelessly for his clients. He has serviced my household in two locations and continues to be my HVAC service provider in my new home. I would not consider using anyone else. They always pay attention to cleanliness covering their shoes and cleaning up after their work. Spyro's pricing is very fair and he is exceptionally professional and equally kind. You will not be disappointed! read more

Our furnace broke down right before the holiday and we were really worried about getting it serviced. Temps outside are in the single digits. Spyros and Tony took care of us within hours. We've been using them for many years and are grateful for their wonderful, reliable, and fair service. You can't go wrong with these guys. read more

The very best and most honest service! Called for repair on a dryer and while here I asked about a totally separate issue and they had a solution. Service was great all the way from the woman I spoke with to schedule the appointment to the two guys that came out. These people are great to work with - professional, honest, affordable, friendly, kind, etc. I will definitely be using their services again! Thank you Climate Source! read more

A Climate Source is an absolutely EXCELLENT business!!! I recently purchased a gas-furnace, and the immediate warmth that my family and I felt inside of our property is priceless, especially during Illinois winters!!! The owner, Spyro, is absolutely OUTSTANDING with his professional character, demeanor, diligence, efficiency, knowledge, and punctuality!!! Please, do yourself a professional courtesy, and contact A Climate Source if you're in need of a new heating-system, because you'll most definitely be happy with the outcome!!! read more

A Climate Source saved the day! Came home to a 52 degree house with a low temp expected tonight of 11 degrees - hooboy. Timing is everything, and an after-hours call serendipitously found Spryos and his guy a block away. They come over, quickly determine my ignitor went buh-bye, replaced and the temp is back to a toasty 68 in no time. Seriously, less than an hour between panic and solution. LIFE. SAVERS. Definitely using these guys when Ye Olde Furnace goes off to that big boiler room in the sky. read more
