Aiello was great! They came the same day and were quick and friendly. They diagnosed the issue with our basement outlets quickly for a fraction of the price of competitors in the area. Would definitely recommend! read more

Stay away at any and all costs. Ruined my finished basement due to incompetence and negligence. This experience was like having front row seats, live to the three stooges. I hired this company to clear a clog in my main drain line. The pipe was knowingly backed up, and despite this, the plumber fully opened the cleanout port anyway, releasing raw sewage all over my finished basement. This wasn't an accident or an unforeseeable issue, it was a basic, avoidable mistake that any competent plumber knows not to make. The result was sewage flooding my basement, ruining flooring and walls, creating a serious health hazard. Never mind the "waste" splatter in my bathroom as well. The most shocking part was the response. After causing the damage, the plumber left quickly and told me to "call a cleanup contractor," taking no responsibility whatsoever for the destruction he caused. No attempt to mitigate the damage. No ownership. No professionalism. This was pure negligence followed by abandonment. I trusted this company in my home and was left with thousands of dollars in damage and stress because of their incompetence. If you care at all about your home, do not hire this company. One reckless decision turned a simple service call into a disaster, and they made it clear they have no intention of standing behind their work. I called another, competent plumber and he fixed the issue in under 15 minutes. read more

Buyer beware. This company will price gouge and try to sell you repairs you don't even need. I paid approximately $366 for a diagnostic visit and was told my well pump and pressure tank needed to be replaced at a cost of nearly $6,000. I was told the system was old and the pump was overheating. Thankfully, I trusted my instincts and got a second opinion. Another company came out and correctly identified the issue as an electrical problem, not the pump or tank and had my water restored within two hours. This means I was almost pushed into a completely unnecessary $6,000 repair for something that wasn't even broken. What made this situation even worse was my interaction with their manager, Kia. Instead of focusing on resolving the issue, he chose to correct my pronunciation of the company's name and made a point to highlight my Spanish accent. When I told him his behavior felt discriminatory, he doubled down and continued correcting how I was speaking. That is completely unacceptable, especially from someone in a management position. No customer should feel disrespected or judged over how they speak while trying to resolve a serious issue. To be fair, after I requested to speak with his supervisor, Scott contacted me. He listened, apologized, and said he would review the conversation and address it internally. He also refunded my money, including the membership fee. While I appreciate Scott doing the right thing, the overall experience including the misdiagnosis, the unnecessary $6,000 quote, and the disrespectful interaction, has completely destroyed my trust in this company. In my opinion, the membership program offers no real value. I will not be doing business with Aiello again, and I will be telling my friends and family to stay away. I strongly recommend staying away from this business and/or get a second opinion before agreeing to any major repairs from this company. #scam read more

Don't hesitate to purchase the Aiello home plan. Called at noon time on a SATURDAY ; the technicians were here at 3 ; my leaking toilet fixed. Good service ,great workers everyone's happy ! Thanks again, Gary B read more

Do not use this company. They lack experience and knowledge while displaying poor time management and very poor customer service. My brother has not been able to run his heat or water in weeks. A pipe burst and they sent out a technician who did not seem experienced or knowledgeable. He was supposed to come back on Friday to fix the pipes so my brother left work early. They did not come and said they had to reschedule for Monday. Monday came around and they said the technician would be there after 12pm. My brother called for updates twice. Both times they said they would reach out to the technician for an update. They finally got back to him at 5pm and said a technician would be out within an hour. Finally at 7pm a technician called and said he could come in an hour IF my brother still wanted him to. Completely unacceptable. Do not use this company !!!! read more

My experience with Aiello has been nothing short of a nightmare. The furnace installation they completed was not only done incorrectly--it was done so poorly that it led to standing water and significant water damage before we even realized what was happening. By the time we caught it, the damage was already done. To make matters worse, this disaster completely ruined my wife's birthday party that we had planned in our home. Instead of celebrating, we were scrambling to contain water, move furniture, and assess the damage caused by Aiello's careless workmanship. No homeowner should ever have to deal with something like this, especially due to a company that claims to be "professional." When another Aiello employee finally came out, he was shocked at how shoddy the original installation was. He openly acknowledged that the previous crew's work was unacceptable and far below standard. If your own technicians can't believe the incompetence of their coworkers, that's a massive red flag about your training, oversight, and overall quality control. Although the furnace was eventually repaired, that doesn't erase the stress, the water damage, the disruption to our home, or the ruined celebration. Aiello showed absolutely no urgency, no accountability, and no understanding of the impact their negligence had on our family. If you're considering hiring Aiello--don't. Their work caused avoidable damage, unnecessary chaos, and emotional stress. A company that allows such poor workmanship to leave the job site is not one you can trust in your home. read more

install team did a phenomenal job, always received a text showing who will be arriving and a timeline of when. Initial furnace was defective from the manufacturer, after replacing parts(no cost to me) they ended up replacing the whole unit for a different one. Again the install went flawlessly and I will be using them again for when I get AC. read more

I would recomend Aiello Home Services if you enjoy WASTING your hard earned money or are filthy RICH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! We had 2 plumbing issues that needed repairs. 1. was a cracked sewer pipe. 2. replace an outdoor faucet. We called Aiello & they gave us an estimate of $2200.00. They broke down the estimate into 2 parts. #1. the cracked sewer pipe $1300.00 & #2. the outdoor faucet $900.00. For a total of $2200.00!!! When they gave us the estimate, I nearly passed out from STICKER SHOCK to say the least... We called another plumber & saved $1700.00 over Aiello. We found a reputable local licensed Plumber that did the entire job for $500.00 total. $400.00 for the cracked pipe & 100.00 for the faucet The parts to replace the outdoor faucet were $12.99 that's $887.01 for a 1/2 hour labor that Aiello's wanted!!! NOW, that's PRICE GOUGING at it's best. Do yourselves a favor & make a few calls before calling Aiello's Home Rip-Off Services. read more

Don't hire them. They are careless and don't install their products well. 1. They installed our boiler and didn't properly vent it. It was leaking carbon monoxide into our house for days. Luckily, we noticed before something fatal happened. 2. After giving them a second chance, they then improperly installed two mini splits and took 3 days and still couldn't figure out why they kept shorting out. My husband figured it out and told them. While here, they left, and left our garage pull down attic and garage side door wide open. I went to go into the garage and ran directly into the open pull down attic door and was injured. I think those points about cover it. Don't hire them. read more

I was charged $145.00 for one 2 lb tub of Bio-Clean pipe /drain cleaner(no installation). Amazon sells the same item for $ 49.95. Total charge to snake one drain was over $500. Will not go with Aiello again. read more

Dustin came to our home to work on an issue with fractured water heater, Heater is 4 yrs old on 10 yr warranty. Another company we called would NOT honor warranty cuz they said town water was at 94psi, too high, Dustin indicated tank says can take up to 150psi. Was here over three hours calling service warranty and Aiello personnel; bottom line, warranty was fully honored, tank replaced saving us thousands of dollars. Very professional, extremely pleasant and knowledgeable genuinely INTERESTED is HELPING US!! Would call them again and again for service. Dustin actually CARED. THAT, means EVERYTHING!!!! read more

Major lateral sewer line replacement, the quality of work was fast and efficient and exactly what needed to be done.vThis was a job that required specific tools and thankfully, they had them. Pricing is in line with industry standards, the real sticking point for these guys was they took the job nobody else would touch. I went through 4 other contractors who all turned me down or gave me astronomical estimates. This company has a heart. As a family of 7 with limited resources, Angelo and his team were able to come up with a plan that we could afford and delivered a solution within 72 hrs. You have my business for life, thank you Aiello. Maurice O. read more

Awful experience. I used them because they were the first ones that came up in a Google search. STAY AWAY!!!!!! The prices are insane. They charged what amounted to over $500 an hour for cleaning and replacing basic parts. My furnace was dirty, but this was a complete robbery. Then when it broke again two weeks later I had to beg for them to come back and wait several days without heat. The technicians were nice enough, but who ever is making the financial calls is an animal. Taking advantage of people who are in need is disgusting. read more

Wow...crazy high quote, like DOUBLE THE PRICE of 2 other plumbers who looked at the same job. What a waste of time and $99!!! read more

I used them for the first time last year, I called and they came out pretty quickly to clean the furnace. I called 6 weeks ago for another cleaning and I am still waiting!!! I called again last week and they told me i was on"stand by". Luckily i found an honest company nearby who came out 2 days after calling them. read more

The response from John is such BS. I literally spoke with the HVAC manager 3 days ago, when he called me from 860-317-0274 at 11:07 am on 12/15/2023. He definitely did NOT want to help me and basically told me to pound sand. They're trying to play it off like they care and want to fix it, but they don't, or they would have last week when I contacted them. Everything they say is dishonest. read more

I won't be using Aeillo again. Called them to snake a clog. They split the work to have a plumber come out to remove and reset the toilet. Charged me $615 just to do that. On top of the $700 dollar to snake a drain which they did thru the shower and not the toilet. Total bullshit ripoff. Sadly I felt they gouged me good. My advice is call around and ask them specifically for the cost of removing and resetting a toilet which is a 5 minute job. Good luck. Don't let them gouge you. Be prepared to get another. You will save hundreds!!! read more

If lying was an art these guys are the best, From price gouging to sloppy work and leaving my house like a dump. When they partially finished the job, They left leftover materials and scrap from my project and somebody else project on my lawn, including a toilet, ( not part of my work) and left. Overall the actual work was acceptable, but they were careless and treated my home like it. They didn't finish multiple things, including putting covers and wall panels back in place. It was obvious that they are overbooking work and clearly dont care about quality, such a shame as this company had a good reputation at one time. If you have any major work that is required, keep looking and avoid this company. read more

STAY AWAY from Aiello unless you like to be OVERCHARGED!!!! We recenlty got new countertops. Aiello came to our house in the morning to diconnect the hoses/wires from underneth the sink and then they were to come back later that day to reconnect everything. They quoted me $2,000. Are you kidding me??? I politely threw the technican out the door. I hired a local plumber that same day for $400. It looks like this is Aiello's standard practice from the reviews I've read. And don't pay the technican the $99 fee. The technican told me I'll probably be put on the "Do Not Service" list. I laughed like hell and told the young man there's plenty of honest plumbers out there I can call. Stay away from these bums!!! read more

This company was AWESOME. My hot water heater was opening down the back seem. The heater was from 1996. Thank God it lasted as long as it did. Well on July 1st, 2022 what happened? Went to basement and saw water. Thank God I did not go away for the 4th of July weekend. I asked 3 different people for their top 3 references. Each list Aiello was on it. I called Aiello and the process was FLAWLESS. Keep in mind it was a Friday, July 4th weekend when all of this happened. From the time I placed the call on Friday morning (10:00 a.m.) to (Christine) at Aiello by Friday 1:30 p.m. I had two installers (I'm aging well so I don't remember their names) LOL came out to do the work. The installers had everything replaced and new hot water heater install in an hour and a half they even pulled the permit electronically. I had to wait another hour for the water to fill the tank and get hot. Just like magic I was back in business and no flooded basement. The town inspector came out on Monday and gave the install a A++ approval. They said the work was spectacular and I passed the inspection. You pay for Cadillac service and not fly-by-night and you get Cadillac work and service. The old saying holds true that you get what your pay for. I have peace of mind and that was worth every single penny. I say try Aiello and you will not be disappointed. Enjoy this HOT summer. read more

Aiello Home Services - New Hot Water Heater - Plumbing Near Me - Windsor Locks, Connecticut

Aiello damaged my home, going to fight them in Court this Month! I wanted a Oil to Gas Conversion and got so many holes put in my house that wasn't needed between the bugs that infested my home and them over charging me for a simple job of redirecting my heating source and not trying to make me a happy costumer they just kept double talking me and it took me 6 months of calling back and forth for them to offer me $500 for damages. My hardwood floor cost me $1500 alone to restain, and I didn't even address the bad workmanship! I still got to paint the mess they didn't fix and they should have left my home in original condition not with mix flooring after putting a hole in the wood flooring, unfortunately it wasn't needed. I will be in Court!!! read more

We needed a new heating system, and I figured we'd start with a quote from a large local company. The sales guy showed up, and asked whether we'd had any quotes. I did have a year old quote of $19K from a smaller company, and when I told the sales guy he LAUGHED IN MY FACE and said, "For the whole system!?". He implied I was either lying, or misstating the work that was quoted. He poked his head in the attic, saw blown in insulation, and said they wouldn't deal with that. We ultimately went with a local company at $25K for a furnace, duct work, and central air. I wonder what Aiello's quote would have been, $40K, $50K? Their sales guy was a total pompous douche. They'll never get another call from me. read more

Friday:Had a leak from second floor bathroom down into kitchen ceiling. A plumber from Aiello come out in the afternoon and took out part of ceiling. Leak detected coming (according to him) from Bathroom sink and/or toilet. Contract to fix: $14,000-$16,000. Monday: Crew arrived and completed work. Plumber said work going faster so estimate $12,000. BUT, for $14,000 I could get repair of drain all the way to basement (which I did). Plumbers scratched and gouged hardwood floors in areas of work. While I was happy to have leak fixed this was a lot of money. Add insult to injury, they took a permit out and never contacted the town to inspect. I called town and was only told that the inspectors are busy and they did not set up an appointment. I called Aiello and they said a letter is sent telling me to call for inspection (no letter received). Lady from Aiello called town and date is almost 2 weeks out! My dates that were set up to reconstruct my home are now cancelled. This company price gouges and does not fulfill their duties. I would check with other companies and now regret using them. If I could have gotten another plumber to come out I would have! read more

Terrible. Way too expensive. Predatory practices such as selling overpriced items to people who don't understand. They sold a $900 kitchen faucet plus installation to a disabled relative who had a small sink. When I complained and requested cost refund he was only given $200 senior citizen discount the service tech forgot to give There was an addition $1200 worth of work for pipes. I complained to CEO and BBB. But no response except a rude service manager If you like them fine, but we did not have good experience Response to John. I spoke with Ty in December. I spoke with other people who share the same stories. Your equipment is overpriced per reliable plumbers. Unless you will offer refund there is nothing more to sayq read more

Getting quotes for a home hot water heater replacement. Aiello was the 3rd of 4 I called. First two are scheduled for free visit to my home to quote my business, neither even asking if I was interested in a standard water heater or state of the art instant hot water technology. Aiello had great online and telephone response process, but wanted $99 for the privilege of earning my business. I rejected their offer to charge me for basically sending a sales guy to peek in my basement and give me a number. What they still don't know is I was also assessing them to see if I wanted to have them quote a complete new HVAC system for my home. They failed without lifting a finger. No water heater business. No HVAC business. No ongoing service income stream. "No nothing." What they did earn was a disgruntled non-customer already sharing my poor experience with friends & family. And, BTW, 4th entity I called for a quote is scheduled for a free quote visit in the same slot I requested of Aiello online. One strike, Aiello's out. The other 3 all will have a shot at a nice new complete HVAC relationship next week. read more

I am very dissatisfied with the way I was treated by Aiello this past week. I need a toilet unclogged at a condo I own in Hamden. They scheduled an appointment the following day and told me I would receive a call in the AM to schedule a time window. After my tenant took the day off work and I drove to the condo, Aiello called to cancel. Their reasoning was that they do not work in non-residential properties. This is AFTER they confirmed the appointment. I complained and tole them that not only was this a residential unit, they had been there before. Well, they could not reschedule the appointment until the next day, meaning another days with out the use of a toilet, another day of missing work and I made another trip out to the unit. The plumber charged me over $400 to unclog the toilet. It seemed high to me but I gratefully paid it. The toilet had always filled rather slowly, and I asked him if that was a problem and he said yes. Without looking into the tank, he told me I needed a new toilet and quoted a price of $1,000. I told him that at that price I'd do it myself. After I took some time to look in the tank I was able to fix the slow fill in about 5 minutes by adjusting the flapper. I hesitate to write a bad review and I tried to just give my (private) feedback directly to the company on its website. I received NO call, no apology, and no acknowledgement that they received my complaint. They don't seem to care. I mentioned above that I have used them in the past, and I thought at the time that the service they provided was pretty good. This time it was really bad! read more

On 1/21/25 Rob and his assistant came out to exchange my water pump and perform maintenance on my tankless water heater. The job costs close to $1200. The next day I noticed my hot water stays hot for about 3-5 minutes and called to have someone come back out to see what the issue was. I was told they didn't have anyone available and I would need to wait until the following week to have someone come out. After much back and forth I was put on the "on call" list for Saturday 1/26. Mike and his assistant showed up on Saturday and proceeded to tell me that my water heater which was fine prior to "maintenance " was giving an error code stating the condenser was shot and I needed to replace the entire system. (Strange since I had no issues prior) Mike says he has no idea what Rob did so he couldn't really help me other than to say I needed to replace the unit. He then stated he would get an estimate to me so I could decide if I want to proceed with replacing the unit. That was 12 days ago and as of today 2/7/25 I still have not heard from anyone at this company in regard to a quote for replacing the water heater. This was my first and last time using this business to service my home. unfortunately the "service" is disappointing to say the least. I'm not sure if all customers are treated this way or just certain ones but service isn't what it used to be. read more

My response to the owner, 7:20 am September 5, 2024 I'm appalled by your response because your technician did nothing other than unplug and then plug the unit back in and what multiple options did he give us? He did not test anything unless plugging and unplugging is testing?Anyone, even someone without intelligence can do that so that's not saying much. There was no unique situation. Your company, had you not been greedy, could have had the job for $400-500 with 45 minutes of work but your price gouging cost you the $1215 you were seeking. You are preying on seniors with these prices and I'm completely disgusted. Were weren't bothered by the service, it was the price gouging that lost the sale! Word of mouth means a lot so why leave such a horrible taste in your customers mouths! Response from the owner 19 hours ago Dawn, we are happy our technician properly diagnosed your problem and was able to provide you with multiple options to resolve your situation. In this case we tested the pump and identified the problem was the float switch for you. We provided options to do a in depth diagnostic, due to the unique situation or to proactively replace the pump at that time. You declined to proceed with either. We're happy we were able to give you the proper diagnosis for your issue and you are able to DIY your project. If you need any help in the future, we're here for you. Thank you for your review. Let us know if there is anything we can do to ensure your satisfaction. read more

Connecticut technician charged me $333 for a $12 valve replacement that took less than 5 minutes to fix. Could have done it myself if I hadn't just had surgery. If you can do it by watching a YouTube video, do it yourself! Also tried to sell me a new toilet for $1400 - REALLY??? On a positive note, technician was friendly. read more

Aiello Home Services - $333 for a $12 piece that took 5 min to install - Plumbing Near Me - Windsor Locks, Connecticut

We paid $100 for a "Precision Air Conditioning System Check" because we foolishly thought it would include routine annual servicing. Our bad for not reading. They came, tested the AC system, gave us a bunch of estimates, and left. This spring we tried to turn on the system and nothing happened. We called a better company and they said the disconnect was in the off position. They turned it on, charged me more money, and left. Only the Aiello tech could have disconnected the power as he was the last person in there. Not sure if it was intentional or accidental. Regardless, we won't ever use Aiello again. UPDATE: Aiello contacted me and refunded their fee as well as the fee of the other company which I greatly appreciate. read more

We had a number of plumbing issues - replacing the whole house water filtration system, replace the handle on kitchen sink, and stop the toilet from running occasionally. Aiello said we needed to replace the kitchen faucet, rebuild the inside of the toilet, and replace the the whole house water filtration system. Aiello told me the kitchen faucet was a Kohler. They gave an estimate of $4,000 for everything including parts. I called a local plumber and he said I had a Moen faucet and to call them because they will replace the handle for free. He replaced the flapper in the toilet and it resolved that problem. I bought the new water filtration system and the plumber installed it. The whole job only cost me $200 including parts. I would give Aiello 0 stars if I could. read more

Charged me $440 to pull/reinstall a toilet (20 minutes of work) which equates to $2000 an hour. Absolutely ridiculous.

On 6/26/24 I received a $22,697 proposal from Aiello to install a new second floor air conditioning system in my house. The proposal called for the installation of a "Mitsubishi 4-Ton Hyper-heating Multi-Zone Heat Pump" and related handlers. The model numbers and related AHRI certificate numbers were clearly specified. I accepted the offer and executed a Sales Agreement specifying the same AHRI number on 7/1/24. Although most of the work was done on 7/19, several small jobs were not completed until 11/1 after multiple emails, texts, phone calls, and no-shows. I finally received an invoice on 11/21 (dated 7/19) which specified the AHRI number and model numbers as specified in the proposal. Unfortunately, my application for the Energize CT rebate (a major item in the sales pitch) continually bounced because the model numbers of the equipment actually installed were not consistent with the AHRI numbers and model numbers in the Aiello documentation. I discovered that Aiello had actually installed a different, inferior heat pump without the hyper-heating feature, which was meant to lower energy usage and eliminate the need for summer air conditioning. I brought this to Aiello's attention many times, but they have not been willing to provide the documents I need to receive the $3,000 CT credit, and this may also affect my federal tax credit. During the course of the installation, Aiello, for some unknown reason, also ripped out my three-year-old, perfectly functioning first floor air conditioner. By the time that I found out about this, they had installed a replacement without ever explaining whether or not it was actually equivalent to the property they destroyed. This foul-up may be due to simple incompetence, or it may be an intentional misrepresentation in the course of a "bait and switch" operation. Aiello's sluggish, grudging unwillingness to handle this situation has led me to ask for a substantial refund. These are dangerous people to deal with. read more

DON'T USE AIELLO!!! Aiello doesn't honor their appointments. I scheduled a routine furnace checkup in mid-October and took the day off of work. I was called the day before and told they need to reschedule me for December. I waited almost two months and take another day off of work, only to have them call me the day before and reschedule me yet again, this time for an appointment maybe January. Aiello would not promise me that I wouldn't be rescheduled again in the future. Their reasoning as it was explained to me: "We need to keep our schedule open for emergencies and customers without heat. We make more money off desperate customers without heat. Routine furnace checkups are a loss for the company. We don't value the time and business of our loyal customers, unless they're despite, in which case we can price gouge them. " Worst company ever! Don't give them your business, you'll regret it. read more

Job was done last year and the sheet metal work is pathetic on the heat exchanger, very cut and pasted. but i did not have expectations. Then I found out recently that a computer stored in my basement where only I go has disappeared. It was relocated prior to the install and now it is gone with the docking station. I reported to the sales rep and no one followed up. now that I am reassembling my workstation during the winter and realizing it never did turn up after a complete relayout of the room. Thievery at the worksite is inexcusable and I would not use these people for anything again. Now I know better what to expect and i will never let anyone work alone in my house. Might need to talk to the police. read more

On demand water heater would shut off with no flow. $200 for "diagnostic" for about an hour, 30 minutes of which was on call with manufacturer service center. diagnosis was new board and flow valve to be replaced aiello returned with the parts (parts covered under warranty so no cost for parts). Aiello tech spent 40 minutes replacing parts. Bill was $1,299.00 I was advised beforehand what the charge would be so i had to approve for them to order the parts. with predefined pricing I guess some customers are winners and others are not. $1,950 an hour seems a bit steep Quality of work was fine, pricing seems high. Might suggest getting a 2nd estimate read more

Grossly overpriced. $448 for 15 minutes job to snake a toilet. Simple 6 foot snake. Oh they took off the $99 quote so $348 and told me both toilets could be replaced at $2800. Tech was pleasant but Aiello's pricing is bizarre. No estimates anywhere on site example: how much a basic snake is, what a bigger job would be, etc. Run - use anyone, anyone else! read more

This review has taken me a bit to write since I have been so upset being scammed over 3000.00 for putting in a propane gas water heater!!! My water heater broke on a Sunday and they were able to come out which started off as a good sign. However, when the town building inspector came it flunked inspection because the piping was installed incorrectly. The pipe was pointing down which could cause carbon monoxide to accumulate into our home!!! Since the water heater they installed is taller there was no room to pitch the pipe up!! They should have known from the start!!!!!!! We immediately called Aiello and they just kept giving us the run around and options that would cost an additional 5000.00. This was definately a bait and switch tactic!! They should have known that the installation was not correct from the start!! In fact when we looked at the owner's manual it clearly showed pictures of how the piping angle should correctly be installed!! Now we are afraid of carbon monoxide poisoning and the cost of having to rip this out and putting in an electric water heater!!! Never Never use these people!!!!!! Horrible Experience!!!!! read more
