We have used AZS for several years for both HVAC service and new unit installation. Great service. Very fast response to issues. Expert troubleshooting and resolution. Did a great job for us every time. They also explain if there is an underlying cause and how to address it (like inadequate return air flow). This solved what had been a recurring issue with previousl service companies. Highly recommend for any HVAC work without reservation.
Description of Work: Over the years and locations - just about everything from new installs to repairing heating or cooling failures.

My wife and I used AZS previously on several occasions for minor issues (thermostat, humidifier, etc) and were always impressed with how responsive, skilled and pleasant Brian and his team were. Well, our ancient furnace just went out and true to form Brian and Mike replaced it without a hitch and at a very reasonable and competitive price. We'll continue to recommend AZS to our friends!

The AZS service was excellent! The technicians were very professional and efficient, and the results are amazing. I love my new dryer vent; it works great! I had previously received bids from many other companies that install dryer vents and AZS had the lowest cost for this service. I am so glad I chose AZS because they were wonderful. I also had requested workers that do not smoke and they were non-smokers, which made me very happy. In addition to installing the dryer vent, they also carried my dryer from a first level floor down to the basement and hooked up the dryer to the vent at no additional cost. They also heard the popping noise coming from my furnace and fixed that at no additional charge. I was very pleased with their work and overall experience with them, and will hire them again for my future heating and cooling needs. I highly recommend AZS to others.

We had 3 different quotations for the work to replace our 25 year old HVAC system and AZS provided the best options to choose from with no up sales pressure. The work crew was very professional and timely with the installation. Our new system works great and we are very happy with the comfort! The addition of the whole house humidifier is wonderful during the winter months! We are very pleased!

Called Brian at 4:55p and had a technician out at 5:15p. Our tech Steve was courteous and knowledgable and got out to our home extremely quick. He knew exactly what the problem was and had the ignitor swapped out in under 10 minutes. I just couldn't believe how quick they had me taken care of. Do not hesitate to call these guys. Their service is top notch.

I don't typically feel strongly about most service providers--at least not positively strong. My opinions usually range from vaguely satisfied to pure disdain of the occasional bad apple. That's not fair, as the good contractors aren't rewarded in the same measure the bad ones are penalized. But, I feel quite strongly about AZS' professionalism, fairness, and capabilities. They're fantastic. They deserve a resounding recommendation. It's difficult to comment on any one particular service call, as I've had AZS out 2 or 3 times each summer for the past six years. I had the misfortune of inheriting two very unreliable central A/C units when I purchased my house. That's to say, repairs have been required frequently as well as the replacement of one of my air handlers and compressors. Every time a repair was necessary, AZS sought the most cost effective option for me (not necessarily the most profitable option for them). For example, they had to replace the motor in one of my troublesome compressors a couple years ago. Last year, that same compressor had to be replaced altogether while the other compressor needed a new motor. They could have easily replaced the first compressor and charged me for a new motor on the second. But, they recalled that there was a like-new motor in the system they were replacing and suggested using that motor in the other unit, saving me hundreds. I had not idea the motor was even compatible. That's just one of many examples in which they didn't have to suggest an unlikely, cost-effective solution, but they did, of their own accord. When an A/C unit fails in July, it's emergent to the homeowner. They're in a time-sensitive and specialized industry. Thus, they could easily get away with gouging customers, and the customers likely wouldn't even know it. But AZS doesn't do that. Because, I suspect, they understand the loyalty they receive in return for their integrity is far more valuable.
Description of Work: Replaced compressors, coils, thermostats, air handlers, etc. (Many service calls.)

Awesome visit! My appointed time was between 9-11 am ( I made the appointment just two days ago so fast service for a non-emergency). The techician arrived at 9 am on the dot. He politely endured my endless list of questions. Chesterfield Service installed the unit and we've had them out annually since installation. Initially they seemed great but over the years the techicians seemed more like used car salesmen than technicians so I called AZS for a second opinion, if you will. First I asked if we really need to change the humidifier pad every year (at $50 a pop). Ours is a year old. He looked at it and asked if it was recently replaced since it looked almost like new!! It pays to ask for a second opinion. He recommends changing about every two years and only if there are dark spots or significant amount of clumps and it's only $17 through him. Next I asked if our electronic air cleaner cells look dirty to him. Every year Chesterfield Service says they're dirty and should be replaced with a disposable hepa filter (~$100 a pop). He said it's aluminum, it's 30 years old, it's not shiny anymore but it's not dirt and it doesn't affect the function of the unit. Oh, and he said he doesn't like the thick hepa filters because they restrict air flow and put a strain on the blower motor. Yikes! He thoroughly checked the heater, didn't seem the least bit annoyed that I remained next to him the whole time, gave me a great education on my furnace and water heater, too. He gave me advice on buying a replacement programable thermostat through Amazon when this one from Home Depot dies. And he looked through all the tickets from past service on the unit, gave me his opinion on each (mainly we over paid annually for a not needed humidifier pad and there were a couple of questionable services just that he'd never seen this unit need so much service but it could be the unit, he wasn't here to test himself), and only charged $109 for an annual service contract (compared to $199 with Chesterfield service), which covered this visit and the spring check up for the A/C. I'm thrilled I joined Angie's list, trusted the AZS reviews and broke ties with Chesterfield Service.
Description of Work: Annual heater check up or perhaps it's called an annual maintenance visit.

They were very good. I was so glad I hired them. They were recommended by our neighbor, and they had a good rating on Angies List. They were friendly and did not try to pressure me into something I did not want. They were very honest with me in telling me what would suit my needs. I highly recommend them. I had an issue with the fan on the unit, and they came right out and fixed it.

We have used this company in the past and have been very pleased with all of their work and responsiveness. They have always been able to come within an hour or two of our call, even on a Sunday afternoon during an ice storm. They are very reasonably priced and do good work. We would highly recommend them.
Description of Work: Our a/c compressor would not turn off and was running even when we turned on the heat. Also, the air was not being cooled when the a/c was on. We called and the repairman was here within 20 minutes (he just happened to be finishing up a call in our neighborhood). He knew right away there was a stuck contact. He replaced the contact and added some freon. He said since our unit is about 18 years old we should cross our fingers and hope it lasts through the summer. We appreciated his honesty.A few years ago during an ice storm on a Sunday afternoon, we called because the furnace would not come on. He was here within an hour and removed a squirrel that had fallen down the flue, and all was well. He did not charge any extra for the Sunday emergency.

This company had recently replaced my neighbor's air conditioning unit and they were very pleased with both the work and the cost. When i called for an estimate, they came the next day, even though it was a Saturday. They were very cooperative in working around my schedule, and always easy to reach by phone They called before they came to give me a time of arrival, and completed the work in a professional and efficient manner. I was not pressured into purchasiing a unit or services that did not fit my needs or budget. They also took the time to talk to me about how to care for my unit to make certain I got the best use of it and to avoid future problems. All the employees working on the unit that day were very knowledgeable and did not hesitate to answer my questions and address my concerns. Everyone also had a very professional appearance. This is a very well-run company.

Called AZS on recommendation of a friend after sorry experience with previous company. Bitterly cold weekend and I was left (69 yr old female and pets) in an unheated house for 3 day weekend ) with no explanation or resources. Brian came out with assistant, brought portable heater for me and stated he could install new furnace next day. Discussed my furnace problem and options with me. New furnace installed in am and house became immediately comfortable. Unit was a Trane, high efficiency, with Honeywell humidifier. All will be eligible for tax credit. He was a pleasure to work with and I wouldn't hesitate to hire him again. I have since called him with a couple of questions and he has been immediately responsive. Remained completely neutral about other company which shows his professionalism. Also good with pets. Highly recommended.

We met Brian at the Home Show and arranged for him to give us an estimate. He arrived at the agreed upon time, looked over our home, and discussed what he thought we would need, giving us a written estimate that included several options and add on's that we could consider. He was informative, but did not pressure us. We got several other bids and decided on his company. They came at 8 a.m. on the designated day. There were two men doing the job along with Brian, the man who had given us the estimate. They were very polite, and they even took a few minutes to befriend our dog, Jake! They worked until about 3 p.m. without taking a lunch break. The new box outside was a different size than our old one, and they even took some extra siding we had and made it look great! You couldn't tell it wasn't there all along! They explained to me how to use the new thermostat, and said I could call with any questions. They left everything as neat as they found it. We highly recommend them!
Description of Work: They removed our heating and air conditioning equipment (26 years old!) and installed all the new equipment. We got a ComfortMaker 100K BTU 80% Gas Furnace, and a ComfortMaker 3 ton air conditioner. We also installed three add on's: humidifier, 3 ton a/c mainline, and an electric air cleaner. We have a 10 year warranty on the compressor, 5 years on parts, 20 years on the heat exchanger, and 1 year on labor. They disposed of all the old equipment.
