HIRE AT YOUR OWN RISK YOU HAVE BEEN WARNED. I paid Matt $17,500 to install 2 heating and cooling…read moresystems in my new house one in the basement and one in the attic. He never came back to finish the job, the thermostats were never installed I was stuck with out heat in the winter. I contacted another company to finish the job thinking Matt had done most of the work and just didnt install the thermostats put on the registers for the returns and a few other small things. Boy was I wrong the company came out and discovered nothing was done to code and half the work wasnt done. The AC systems were not energized and had no fluid. The heating system in the basement wasnt wired up to the breaker, the condenser pump wasnt connected and there was no on and off switch. One of the AC units outside was a different brand then he said he would install. His guys threw out my warranty manual so the new equipments warranty was never registered he said he would get the model number and do it he lied and never came back. None of the AC units were wired up they ran a wire into the house that was just hanging in the ceiling nothing was connected. The wire was outside bare and wasnt covered with a weather proof membrane so it started to root. NOTHING was done up to code the condensate and exhaust line was set 6 inches off the ground they told me if it snows I have to come out and clear the line because if snow covers it my heat would cut off and carbon monoxide would back up into my house. The attic heating units internal wiring was wired wrong, they jumped the wired to constantly call for AC on the board but since they didnt power up the AC the fan on the heater just constantly ran and would never cut off. I also had a vent in the the play room that was feed with soft duct work and in was closed off so no heat got to that room. Also the duct work was installed wrong it is suppose to get smaller as it gets to the vent to push out the forced air. They never reduce the duct size so none of the vents blow forced air it has no pressure. Honestly the amount of issues are too many to list. All in all its costing me an additional $6000 on top of the money I paid Matt to fix the issues. When I asked him to come install the thermostats he told me he was doing me a favor and threatened to punch me in the face. I WAS RIPPED OFF BY THIS GUY. I am working with my lawyer to handle this situation currently, he is a con artist and will turn into a different person as soon as he gets his money from you I made the mistake of paying the final payment to early. To bad I didn't read his Yelp reviews until after I got scammed.

At that exact time, I was getting ready to call and cancel because I had already troubleshooted the issue myself and confirmed my system was working normally, so the service was no longer needed. When I originally called, the only fee mentioned was a $120 diagnostic fee. There was no mention whatsoever of a no-show fee or a travel fee. Now they are trying to force me to pay a $59 travel fee, even though the technician arrived before the scheduled appointment time. To make matters worse, this fee was not explained to me until after they had already shown up. Completely unprofessional and misleading business practices.

I recently (within the last few years) had mini-splits installed all throughout my house. No less…read morethan 6 Heads and 2 outdoor units capable of 4 heads apiece. I had a three company bidding war going on to see who would, in the end, give us the greatest value for our system. It turned out that Aire Serv, through the owner's brother, gave us the best equipment for the best value. So we went with Aire Serv... and then I've had nothing but headaches since. 1. One of the six heads iced up thick enough make snowballs. One of the installers connected the refrigerant line from another head to it, so it iced over even though it didn't need coolant. 2. My largest head carrying the most load has had issues since very shortly after installation. I was told "there's nothing wrong", "there's not enough coolant", "there's too much coolant", "there's nothing wrong" again, "it's your fault", and finally one of their technicians correctly determined the blower wheel motor was defective and got it replaced, but not until being gaslit for no less than probably 4-6 technician calls. 3. When I went to purchase the maintenance agreement, the owner's brother never told me the price he was quoting me was for only 1/2 of my system. Imagine my surprise when the maintenance agreement was double the price. 4. One of the heads leaked water over my original hardwood floors and caused damage. Why? Because an installer didn't wrap the refrigerant line in insulation so it condensed and ran down my wall. Their fix? sand it down until you can't see the damage. 5. I was told by one of the technicians "I'm not sure this system was designed correctly. You probably need another head for your main living area". Awesome! So the system I purchased wasn't correctly sized or designed? That's just great! No wonder I feel like the system doesn't do a good job of keeping my living space cool in the summer time. 6. And now, I'm being told if I want to maintain my warranty that I have to purchase surge protection for over $1,500. It can only be installed by them. I can't get my own protection or contractor. I'm pretty sure a post hoc change like this is illegal, but I'm not a law professional. I would encourage anyone who is in law to look at this review and consider reaching out to get a class action together. From what it sounds like, Aire Serv is doing this to all of their customers. It's not OUR, the customer's fault, that Aire Serv did not have the foresight to consider that surge protection would be a great idea for installations... but they certainly are trying to make us pay for their hindsight. I would NOT recommend Aire Serv. If you have a modicum of handy homeowner skills, just get a Mr. Cool DIY system from home improvement stores for 1/4 of the price. Or better yet, just buy the $400 in window mini-split units that look like legacy window units and save 90% of the cost of install. If you don't or can't install it on your own, there are other HVAC companies, like Moon Air. Don't get me wrong, the system works 75% to my expectations. Mitsubishi makes great mini-splits. But go through another company other than Aire Serv - they are the problem.

TL;DR: they refused service to long-time clients because we had the audacity to ask for a measly…read more$200 off their HVAC bid. Clients of theirs for years, no complaints. When we needed a new HVAC, we got an estimate from Frederick that was $1000+ over the estimate from another long-time, reputable local company. But out of loyalty to Frederick, we politely asked if they would shave $200 off to come *slightly* closer to this other quote. We actually hate haggling, but had read that you're expected to, for new HVAC. Can't hurt, right? They responded. Had they just said, "No, that's not possible due to XYZ," we would have hired them and paid the full price. But instead the rep explained why it wasn't possible, and then, in a polite but insulted tone, *rescinded their bid*, essentially telling us they would not be doing the job either way. All over a request for $200 off a $7000 job. We were stunned. Needless to say, we haven't called them for anything since, and we're the kind of easy-going, non-complaining customers contractors usually like to have. We got our HVAC at the other place and it's running fine, a few years later. Owner, if you're reading this: I get that you're doing well enough that you don't need to accept anyone's attempt to haggle, and can charge a lot more than the competition. Good for you. I'm purposefully not giving you a 1 star because I don't believe in trying to hurt someone's business. But talk to your guys about not reacting in a personal way to long-time customers. The reaction we got was really uncalled for. Maybe the guy was having a bad day, but you have to leave that behind when you're interacting with a customer, especially an established one. He could have just said "No, we can't do that, but let me know if you want to proceed with us." We would have.
