"I recently had a new HVAC system installed by Aireserv, and I couldn't be more pleased with the results. From the beginning, the team was professional, courteous, and informative. They arrived on time and were very thorough in explaining the detailed installation plan, the features of the new system, and how to operate it. The installation went smoothly, and the technicians cleaned the area while working. Once the system was installed, they ran tests to ensure everything was working perfectly and took the time to answer all of my questions. The new HVAC system has been a game-changer in terms of performance. It heats and cools my home more efficiently than my previous unit, and I've noticed a significant improvement in comfort and air quality. The system runs quietly and maintains an even temperature throughout my home. I also appreciate the energy savings I'm already seeing. My energy bills have been noticeably lower, which I can directly attribute to the new system's efficiency. Overall, I'm delighted with the service from Aireserv and the performance of the HVAC system. I highly recommend them to anyone in need of HVAC installation or upgrades. They provided excellent service from start to finish! A BIG THANK YOU TO ALTON THOMPSON AND HIS TEAM FROM AIRESERV."

"This guy is a real pro! The original installer came out and gave up on the problem, and I never heard from them again. Duke came out, and diagnosed the issue in an hour. He even submitted the request for a part under warranty, received it, and came back to install it 2 days later. The cost was very reasonable. Thanks Duke!"

"We had a wonderful experience with Comfort Energy! The service person, whose name was Chance, did a thorough evaluation of the problem with a focus on saving us as much money as possible, to either repair or replace our 30-year-old heat furnace. He quickly determined that our inlet filter was too dense (it was a Merv 11 and should have been a Merv 8) and that that was probably causing the heater to go off an on every 5-10 minutes. He then tested and confirmed his hypothesis. He also performed a CO test to make sure there wasn't anything more serious going on. Finally, he gave us a good idea of replacement options, which we should probably do before the next Winter, but not necessarily right away. All in all, this is exactly the kind of assessment we needed, and it cost orders of magnitude less than what was estimated by the first service company we had come out. Chance was great, and Comfort Energy is our go-to for heating and cooling service and/or installation from now on."

"My wife and I bought a house a couple years ago, and became owners of a radiant heating systems installed more than 20 years ago. Tony and Damian did a great job of understanding how my radiant heating system works, what repairs were needed/what was failing, and where upgrades were needed. They replaced the pump, both expansion tanks, and the neutralizer. Additionally, they noticed the hot water tank was installed incorrectly, and the hot and cold water connections were flipped. It's amazing the system worked, and it's nice to have a system that's correctly installed (even if it's 20 years later!). Additionally, they secured the expansion tanks to the wall (now required by code), replaced the deteriorating copper pipes connected to the neutralizer with plastic (I'm sure this is code now as well), and re-routed the overflow pipes to the outside (rather than the floor!). You can't go wrong with these guys, well done, they're true craftsmen to the trade."

"These people were real pros. My heating boiler failed - it was only 48 years old!!! They installed a completely new system and lent my tenants heaters while the boiler was on order. They were very good at getting back to me and excellent at explaining the work they would be doing."
