Our History
Founded in 1996 by Jerry Ralston, Diamond Heating Comfort Systems quickly grew from just three employees into one of Alaska’s leading residential heating and cooling companies. In 2006, Diamond Heating Comfort Systems joined forces with AirTemp Alaska, expanding its capabilities and strengthening its reputation as a trusted provider of heating, ventilation, air conditioning, and indoor air quality services throughout Anchorage and the surrounding communities.
In 2023, the company came under new ownership, and Andreas Refvik has continued the commitment to exceptional customer service, quality workmanship, and community involvement while building on the strong foundation established over nearly three decades.
Today, Diamond Heating proudly serves homeowners and businesses with an experienced team of professionals offering residential service, maintenance, repairs, system replacements, and light commercial HVAC solutions. While we’ve received recognition for our growth and service, our greatest achievement continues to be the trust and satisfaction of the customers we serve every day.
