Different than most! Four Seasons Heating and Cooling is not only family owned but also owner operated. That means the owner will be answering the phone, greeting you at your home and looking over every detail of your project until it is 100% complete. Aaron is a 2nd generation HVAC journeyman with over 25 years experience in the HVAC industry. Much of his time was spent working for large commercial contractors in the Seattle area. Looking for a more family oriented lifestyle Aaron started the business in 2013 with a  vision of providing residential and commercial clients with craftmanship that was built on relationships fostered through honesty, integrity, and experience. Shortly after the business started Aaron and his wife moved their family to Whatcom County and found Lynden to be the best place to raise a family. Aaron and his wife proudly serve the community they live, work and raise their children.
