About Celtic HVAC/R

Our beginning's date back to 1998 when founder Declan Kelly branched out and started a company with a focus on superior workmanship, and customer satisfaction. That company was Celtic HVAC/R and to this day we are still family owned and operated. We continue to uphold the core values that Declan founded the company on nearly two decades ago.

After Declan's retirement in 2011, son and business partner Darran took over full time operations at Celtic, and the core philosophy hasn't changed. Celtic continues to stand out amongst other contractors. We accomplish this by providing fast response times and skillful problem solving. Celtic operates 24 hours a day, 365 days a year, just like you do. We know all too well that issues arise when you least expect them and that’s why we are always available. 

We approach each and every install or repair with care and concern, because at the end of the day your success is our success. We also feel it is the responsibility of the contractor to educate the customer and empower them to make informed heating and cooling decisions for their home or business. This approach has helped us to develop close working relationships with many local businesses and home owners.

At Celtic we offer hvac service, maintenance, and installation of all makes and models of heating, air conditioning, and refrigeration equipment. We service the residential, commercial, and industrial sectors in Calgary and surrounding area. We guarantee your peace of mind, and satisfaction by offering a one year parts and labour warranty on any and all service work. We also offer a five year labour warranty on new installs so that you can be assured of the longevity of your equipment. We look forward helping you with all of your heating and cooling needs.
