Fast and professional service. The CHC team got my a/c working in no time and for a better price than other contractors in the area. They will certainly be getting my business again! Thanks David.

David was patient in explaining the whole process. everything was scheduled right away. Technicians swept up after completion. Would highly recommend Cary and his company.

Very friendly, great work, clean and polite. Great job. I have used Constant in the past for furnace repair as well as air conditioning. Would highly recommend this company.

David from Constant is fantastic; he's super honest and helpful, and a pleasure to deal with. I'd recommend him in a heartbeat and I will ask for him next time I need hvac services.
