I’m not a person who writes reviews but I have to give credit where credit is due. This is my third time having my heating/ air conditioner/ generator serviced by Anthony of Belair Engineering. To say that he’s an excellent technician is an understatement. He’s very knowledgeable, professional, and competent. I have no worries or concerns when he is on the job. Besides that, he’s a very humble person, kind and considerate, easy to talk to. He is an all around good person. I will always request him for service. Belair Engineering, Anthony is a keeper. He deserves his pay and much more.

On May 21, I called Belair because my AC was not blowing cool air. A technician named Hugo arrived shortly after my call. He conducted a thorough inspection and informed me that the indoor evaporator coil was leaking. He said he would order a replacement and return to install it. I found Hugo to be very knowledgeable and informative. Today, June 2, Hugo and Alexis came to remove the old evaporator coil and install the new one. Both Hugo and Alexis provided excellent service. I’m happy to report that I now have cool air flowing again. Thanks, guys!
