Originally Bel-Air Engineerring was merely the company who serviced my HVac system. In July of 2023, I came back from vacation to a system that wasn't operating at all! Contacted my "supposed" Home warranty servicer who informed me they couldn't get anyone out until the following week! I contacted Bel- Air the sent a rep to take a look and determined I had gotten all I could or would get out of the original builder grade system. At that point I made the decision to have them replace it. Got a really great price and install was scheduled within a very timely period. Prior to the install Bel-Air sent a tech out and provided temporary window units to alleviate the stifling heat! Having said all the above, Bel-Air is and will be my go to for anything HVAC related. I received the same stellar service this morning when Yahony came out to perform my spring inspection! He was Professional, on time, and explained everything he did! Class act as always!

The technician was so great, he fixed the problem and he educated me on my furnace and air conditioner. I would recommend this company to my friends. He was really good at his job.

Julius reconstructed my kitchen drainage system and did a great job

I have been a customer of Belair Engineering for over 15 yrs. All of the Service Technicians are very professional but, Anthony has been the best. He always takes the time to answer my questions & explain the description of the work performed.

Julius went above and beyond - we cannot sing his praise enough!! He chased down a rare part needed to fix a problem that plumbers have given up on for over 15 years. We finally have hot water in our guest bathroom shower -hallelujah!!! You just don’t see that level of customer service anymore. I’m a Belair customer for life! 😍
