Hvac Reviews in O Fallon


I was pleased with the service provided. The technicians were able to install in the amount of time estimated. They were thorough in explaining how to utilized the humidifier and settings. I hope to use them again for annual service tune-ups.

is very friendly and professional. He answered all of our questions and explained the process in detail. Can't say enough good things about him or his work. My only complaint was that he was late arriving on most days (several hours, in fact). I would call him and he would say that he was "on his way" but didn't arrive until hours later. This happened more than once. Once he arrived he worked very diligently on the job. I will use
again because, in the end, he did an excellent job!

Hvac reviews in O Fallon


I called several heating & cooling companies when our furnace wasn't working properly on a bitterly cold day. I asked them if I could describe the problem before scheduling a service call so we would know what the damage might be. (Of course, not holding them to it as they hadn't looked at the unit yet). Most companies blew me off or told me it was something horrible and said by the age of the furnace, we'd likely need a new one.

gave me advice on

things to check ourselves and fully explained everything that we needed. The also let me schedule an appointment so that we had a time slot that day but were fine with me canceling if one of their suggestions worked. Well, it was a

fix. Their advice saved us time and money. Not many companies like that nowadays. For this reason, they will be the first company we call with any heating or cooling issues. Thanks

inspected the furnace thoroughly & I was advised that the capacitor and Igniter may need to be replaced in possibly another year or two - although not now.

answered all of my questions & was very gracious. What a fine representative for

. He cleaned up the work area much better than it had been when he arrived.
I will probably contact

in the near future to arrange for another inspection this fall & will likely want to set up a regular schedule for both heating & a/c inspections since my house is now 8 years old. If I do, I hope that I will be fortunate enough to have

come to inspect the furnace. While I know that any service person from

My furnace was not working right so I called
O Fallon HVAC Contractors Provider Name Locked
from a networking group I am in. They came out and checked my unit and found out the person who put this unit in put in the wrong one and it wasn't working right. They made the necessary adjustments and it is working great now. Jade is the salesman who came out. He was professional and had a firm knowledge of what needed to be done and how much it was going to cost. I would highly recommend this company and would share their information with anyone I knew.

They were great. Someone came out early in the am to evaluate. He called me to explain the problem and my repair options. I chose one of the options and we were cool by evening. I appreciated their ability to get to us quickly and the great communication

They called us prior to coming out and arrived as promised.

knew what the problem was immediately and ordered a new wheel for us. We had to wait until the wheel arrived (which was the same day) and

came back & installed it. We also purchased a maintenance agreement with them because

did such a great job and the service was excellent. The total we spent included the maintenance agreement in which they come out twice a year and inspect and clean the furnace prior to winter and inspect and clean the air conditioner prior to summer. I would highly recommend them for air conditioning service and/or furnace service.

Our heating and air unit started making loud noises right before Christmas that sounded similar to what it had done in late spring. A technician came out and said that a few parts needed to be replaced because they were worn down. The parts had to be ordered. The heater actually gave out the night before the technician came and replaced the parts and told us that everything was under warranty. We have been pleased with the professional attitude that all of the technicians have.

We called on a Sunday afternoon on my brother's recommendation. Our fan did not seem to be kicking on to distribute heat through the house. Our system was very old, so we knew we were probably in for a replacement scenario. Even though we called on a Sunday afternoon, they sent someone out in less than an hour. The technician looked at system and said the fan motor was burned out and would need a replacement (about $600) but that he would not recommend it as our system was so old, and could have cracks which would require it to be condemned, which he wouldn't know until the fan was replaced. We decided to look at the options of new systems. He was very forthright, not at all a hard sell. He told us there were likely cheaper systems, but once we heard about the 12 year parts and labor warranty, we felt that any price differential would be offset. We chose a 95% efficient furnace with humidifier, and new A/C unit to be installed at the same time.

They came out THE NEXT MORNING! The guys were extremely efficient and courteous. No foul language. They were done before 2:30pm. Everything was left cleaner than when they got there. When they took me outside to show me the exterior vent and A/C unit, the technician stopped twice to pick up a piece of trash that was on my lawn (not his mess, mind you!). I was really impressed. Quite rare for a younger guy to have that much awareness and conscientiousness.

I am noticing a much more comfortable heat, which I think must be the humidifier addition. I really like the nice programmable thermostat, and the included carbon monoxide and water detectors that they left. It's peace of mind w/ children in the house. I think we'll all sleep better and more comfortably tonight.

I would wholeheartedly recommend this company, and we will be using them for the systems maintenance in the future.

After spending nearly $400 with another service company (Fresh Aire) just to figure out what the problem was with our air conditioner, we decided to call
O Fallon HVAC Contractors Provider Name Locked
System to actually fix the problem. They had installed a humidifer on our HVAC system several years ago and we were very happy with both the work and the price then. In this case, ACS was able to do the job for less than what Fresh Aire quoted us. They did the job for the price quoted, at the time and date promised. And they didn't try to sell us extra services we didn't need. I've never had a problem working with this company.
