What our customers say about us


As a local home builder, I use Comfort Expert for all my HVAC without thinking twice. Alex and his team are very friendly and professional. From rough to finish, Alex is constantly concerned about efficiency and quality. Every time we feel like we are backed up against a wall, Alex always provides an elaborate solution. Also did some property management in the past, Comfort Expert was my first choice for the HVAC repairs and maintenance as well.

We just got a brand new unit and I was surprised it took only two days. I’m very happy our owner picked this company. I’m so use to hearing the air conditioner turn on and run. The first couple days I forgot we had a brand new air conditioner and was upset I couldn’t here it turn on. I kept saying another bad air conditioner. We haven’t had air contain for three months and I’m in heaven.

I was in need of a new central heating and air unit, and I was refered to this company. I don’t know much about AC units so I didn’t know what to expect. I met with Alex and he went over everything he was going to do at my house. Not only did he do everything that he promised, he did it at a better price than a different company I received a quote from, and on top of that he installed all new ducting since mine was from the early 50s. I will definitely be referring any friends or family in need of any heating and air work.

Our heater stopped working right before the holidays and during very cold weather. I called Comfort Expert and Alexander fixed it the same day. He found the problem and he had right parts to fix it. Giving 5 stars and I would recommend to others.

Great company! We have used Comfort Expert on several occasions. We hired Alex to install the entire HVAC system from ground up for our new custom home. Selection of the right systems and precise airflow calculations provide consistent temperatures through out the house all seasons. I highly recommend Alex and his crew at to anyone who is looking for a true Expert and expects nothing short of Quality Service.

Alex is great. He is on top of everything and is very knowledgeable and professional. After conducting a lot of research, I thought I was fairly knowledgeable on the specifics for my house. He provided a lot more insight though. He’s very particular about making the home as energy efficient as possible.

My project was a complete home remodel; not just the HVAC system. Alex and my contractor have worked together for years, so Alex actually fabricated the necessary sheet metal for my exhaust too. When the hardwood floors began to be sanded and refinished, Alex did not want to finalize the install because he was concerned the hardwood company would get too much dust in the system and ruin it. He contacted my hardwood floor to work with them to provide the necessary knowledge and training to correctly maintain the system when performing such work.

During my remodel, my boss informed me she needed to redo her HVAC as well. I referred Alex and she was very happy with his work as well.

Alex has gone above and beyond and I will recommend him to all my friends.
