Our Story
Chason Service Engineers, Inc. was founded in 1946 by Earl Chason and his family. Their mission: to provide customers with prompt, high-quality HVAC service for their air conditioning and heating systems. Earl made the decision that when it came to installations, his customers’ needs would best be met by the premium products manufactured by Carrier.
Guaranteed Customer Satisfaction
Chason Service Engineers, Inc. is the oldest Carrier Factory Authorized Dealer in the area and a recipient of the 2007 President’s Award. Whether you are looking for repairs, a new system, better humidification or cleaner indoor air, Chason Service Engineers, Inc. should be the first company you call.
“Our customers have my guarantee that we will provide them with the quality of services and products they want for their home or business,” says Bob Chason. “If I didn’t believe this statement, I wouldn’t allow my home phone number to be given to all of our customers.”
Family Owned & Operated Since 1946
Since those early days, Chason Service Engineers, Inc. has continued to live up to the standard of excellence first set by Earl. Bob Chason, the current president and Earl’s son, makes sure that every employee:
- Gives customers the kind of care and attention they should expect from an HVAC contractor.
- Stays current with the technological changes that occur in the industry, through manufacturers’ schools and other forms of training.
