Frequently Asked Questions
Do you service both residential and commercial HVAC?
Yes. DB Enterprises services homes as well as commercial buildings — rooftop units, make-up air, and refrigeration for restaurants, retail, and light industrial across Calgary and Southern Alberta.
Do heat pumps actually work in Alberta winters?
Modern cold-climate heat pumps hold their rated output well below -25°C, and we typically pair them with a gas or electric backup in a dual-fuel configuration, so you get the efficiency without cold-snap risk.
How often should commercial refrigeration be serviced?
Twice a year at minimum for condenser cleaning, door seals, and refrigerant checks. Our maintenance plans schedule this automatically and send reminders before each visit.
