I've been a customer of Belair Engineering since 2001. Their service is excellent and their technicians are very skilled and knowledgeable. Abe has been coming to my home twice a year for winter & summer maintenance and he is terrific!

My service technician was Julius Ford who provided great advice and fast service. He made my day and put my concerns to rest. Thank you Mr. Ford

Hugo did an amazing job diagnosing and fixing the issue I was having with my AC unit. He was punctual, polite, and knew exactly what he was doing. Along with all of this, he also explained everything he was doing in detail, and provided tips in terms of what to look for in order to prevent the issue from repeating itself. Before he left, he did some final checks to make sure the external unit had sufficient charge, and the price for the service was very respectful. 10/10 experience with Hugo and I’d highly recommend to anyone else!

The technician was professional and explained everything very well.

Great setvicr

Tony saw the electrical connection on my hot water heater was sparking while showing me the new valves just installed.

All employees, from the lady who answered the phone to all the repairmen, were quick to respond, very polite, & Showed Up On Time. They each got everything that was possible to be done quickly & gave me good info about the work needed. A bit pricey but very satisfied!
