HVAC Services in Des Moines, WA

Des Moines has a character all its own. A waterfront community with a thriving marina, stunning views of the Sound, and residential neighborhoods that have been home to families for generations. Treat's Heating & Cooling serves Des Moines homeowners with the same honest, dependable service we've been known for since 1973.

Your Trusted Des Moines HVAC Contractor

Des Moines sits on an exposed bluff above Puget Sound, and that elevation and proximity to the water mean consistent marine winds that can drive up heating demands in winter. The area's coastal exposure also brings salt-air moisture that can corrode outdoor HVAC components if units aren't properly rated and maintained. Summers are comfortable but increasingly warm, and homes on the western-facing slopes get direct afternoon sun that makes air conditioning a welcome addition.

The residential neighborhoods along Marine View Drive and Cliff Avenue South feature a mix of 1960s-70s homes with original gas furnaces and updated systems. The neighborhoods east of Pacific Highway near Midway have a range of home ages and system types. Many Des Moines homeowners are upgrading to heat pumps for their dual heating-cooling capability, eliminating the need for separate furnace and AC systems.
