He fixed the gas leak issue quickly, gave me good advice with respect to the next steps and charged me $226. It doesn't take much to realise that well priced contractors like this are few and far between especially on a Sunday for what amounts to emergency work.

I contacted Sam to help resolve issues with my A/C in my condo unit a few months ago. There are…read moresome characteristics I really liked about Sam. He is very professional, answered my calls and got back to me promptly. He also worked around my schedule to arrange an appointment that was convenient for me. He was upfront about the cost and process, and took his time with his investigation. It did not feel like a rushed visit. In terms of his professionalism, I would give him 5 stars. Unfortunately I was not satisfied with his work. He was able to successfully rule out the actuator valve as the issue, but was incorrect with his diagnosis. He believed it to be the temperature of the water supply to the building, which turned out to be incorrect. I ended up having to go through my building's contractor, who traced the issue back to the control panel. Again, Sam was extremely professional but ultimately was unable to resolve the issue for me - which is why I would not go with him again.

I contacted Dave thinking I had a minor issue with my furnace. He looked at the issue with…read morefurnace/thermostat, only to discover that there was a much larger issue. He gave me very good options and even worked with the manufacturer for the warranty of my furnace. The manufacturer gave us a significant discount to get a new furnace, I needed to replace my 20 year old furnace anyway. My furnace crashed again the Sunday before the furnace installation, he came to make my furnace temporarily work with no extra charges. I have worked with 2 other companies before and have contacted numerous ones. It's the first time I can say I highly recommend an HVAC company for the price, timeliness, and effort to make things work for a customer.

My family and I have been dealing with Exallan for years now. They came clutch for us when my AC…read moreunit died on me a few years ago. Recently, on the coldest day of the year, my furnace decided to quit and needed immediate attention. Within hours, they came in, diagnosed the situation and came up clutch with a full replacement part with warranty to keep the furnace running and saved me a ton of money from buying a new unit. They literally are life savers and I can't thank Exzar and John enough for the immediate rescue. They are professional, prompt and honest. A+++

This was our first time to use their services and Exzar sent his professional and very skilled guy,…read morehe did an excellent job fixing our leaking furnace and installed a humidifier to our satisfaction. Before he sent his guy over, my husband was on the phone with him and he ably assessed the problem right away, and figured what spare part he had to order before sending his guy to save time and effort, which was great! The second time we had a problem with our two-month old washer, we called Exzar on the phone and he did not hesitate to advise my husband what to do at no cost. Thank you very much Exzar for your excellent customer service and expertise.

They said that there would be 250 dollars for diagnostics and I agreed. They came and concluded that the pressure from the pump was not sufficient and it needed to be changed.I agreed and paid 1146 dollars fo the pump. But the problem was not fixed.I calked them again. They came again and spent much time waiting on the phone for Navien to support them. Then they said there was a problem with the ignition module and replaced it and-still no solution .Then they visited again, and this time, they told me that venturi needed to be changed and billed me 9 hours of work at 125 dollars per hour.But my unit is still not working. I asked to cancel the invoice because I have no control over the number of hours, and also,although I had to pay for several parts and labour, the unit is not working.I have been waiting to hear about the cancellation of the invoice, but there has been no response yet.I don't recommend these people .Tehy can not solve the problem, but still,they bill you for many hours.

We have used A1 for almost everything in our house and find their work to be adequate at best…read more Normally I find their work falls short of expectation. For example, a few years ago I had a furnace manifold that got stuck. They offered to replace it but only replaced the upper part and not the lower gas line even though it was rusted. I later found out that the price I was charged should have included the replacement of the lower gas line. This season I had them do fall maintenance on my furnace and the technician lowered the temperature on my water-heater without asking. But this caused the pilot to go out. When I complained they just shrugged. I will most likely use a different company going forward.

Before the install happened, Humzah spent his time going over the different furnaces, time it takes to install, what to expect and full cost. He was very thorough and patient. I have contacted other HVAC companies before and haven't received as good service. Humzah came in did the install which went smoothly and ever since there has been no issues. I would highly recommend his services and will definitely be calling him for future installs or fixes that I may need.

He's been out for several jobs at both my home and my grandmother's, including replacing broken shower handles, fixing her HVAC heating just in time for winter, and installing a dishwasher for my house. Every job was done with care and attention to detail. He explained every detail to me, he was very thorough, kept the area clean and cares greatly for safety. I also really appreciated the app he uses--it made it super easy to see a clear estimate breakdown, communicate with him, and make payments without any hassle. He even helped a friend of mine by refitting an outdoor gas line, and they were absolutely thrilled with the results. If you're looking for a professional who's dependable and skilled, they are the ones to call!

The central air conditioner unit came with our house, built in 2000…read more In 2021, we purchased a brand new unit from Convertible. This year, 2025, we called them to report it was not working sufficiently: temp is set at 23, but the house registers 24.5 degrees! They want to charge $150 just to come out and inspect the problem. The original unit lasted approximately 20 years without an issue. This new Carrier unit installed by Convertible is just over 4 years old and it's unable to maintain a comfortable temperature of 23. Recent heat waves are a good test of the quality of an air conditioner unit, as well as the reliability of the company you hire when you need a new one. Disappointed in both!

I called for service and Gregory was here first thing this morning, He changed the capacitor in the air conditioner and cleaned everything out and even moved the air conditioner away from resting on the house wall. He also explained that my leaving the unit off until it was unbearably hot was not a great idea. the service was fast, Gregory was professional and efficient as well as very personable. Since 2006, I have purchased a furnace, air conditioner and tankless water heater for two houses and have been very pleased with the quality, the service, the staff as well as the price. I highly recommend this company. And the sales person I dealt with on both occasions was Marnie Amodeo. She was exceptional at helping me find the exact products I needed for my homes. I highly recommend this company.
