“Great Install by Hoffmann Brothers. Both Jon and Ben provided excellent service during our recent HVAC install. We needed some ductwork repair and replacement as well. Jon and Ben used their camera system to find the problem areas to avoid having to demo a lot of drywall to fix our problem. They also tested all components to determine where the problems were and allowed us to reuse the existing AC line set, which saved us even more money. I highly recommend Hoffmann Brothers, Jon, and Ben. They are great!“

“My fan stopped blowing a couple of weeks ago and it was so hot without the air conditioner blowing. I called these guys and a tech was at my house the next day. Gave me a quote of 1500$ because my house and system are pretty old and he didn't even think they made the parts for mine anymore since it mine was discontinued. Well 1470$ was alot easier for me to come up with than buying a whole new system (single mom) but he called around and found the parts he needed. Came out today and got it fixed. Charged me half of what I was expecting to pay. Didn't need one the parts. The 2 techs who did it were so nice and they didn't pressure me to get a new unit which I really do need but I can't afford it. Its working great now and ending up paying less than I thought was so amazing. I definitely recommend this place. . They were great!!!!“

“I am so grateful to have found Aireserve. They are the most talented, professional individuals I have dealt with related to AC service. I was thrilled to find out they also have other services including electrical and plumbing. They were able to identify the problem, create a solution to get our home taken care of including recommending a company to fix all the water damage done by improper installation of AC units from another company.
Prior to this, we had 2 new AC units replaced in our home about 2 years ago from another company. Since the prior company’s install, $40,000 later, we have had to call them back out at least 10 times, due to water condensation ruining our ceiling, AC units shutting off and/or not cooling at all! We kept calling them because we were $40,000 invested and we felt like they needed to make it right. Then this summer season started and they have already been out 2 times due to units not cooling and just last week again units stopped working while adding more water damage to our home. I finally decided that it’s time for a second opinion and we called Aireserve. Apparently, the prior company did nothing to address condensation and water has completely destroyed our attic area, ceilings and walls on the 3rd floor of our 2m dollar home. Now we have to have the ceiling and walls repaired due to all the water damage. Thank goodness for Aireserve identifying the problem and creating a solid solution to finally address this issue, for good!“

“They installed the toilet, vanity, top, faucet, and trimmed out the shower ...
It all looks great !!!!“

“Eric from Xcell Williams Heating & Cooling stopped by today. He got me signed up again for their seasonal maintenance special. As usual, he did an excellent job with my furnace maintenance. He was professional, thorough, and friendly. I love this company—they’re the best!“

“Shawn and Nick are absolutely wonderful to work with. I would 100% recommend working with them. We had a problem with our air-conditioning unit. Called them in the morning and the problem was fixed by that same afternoon.“
