Heating Services in Chehalis

Furnace Installation and Replacement

Older Chehalis homes often have furnaces that were swapped in without resizing the ducts. We size each replacement with a load calculation so it heats the whole house without short cycling. See our heating services.

Furnace Maintenance

A fall visit is the time to catch a cracked heat exchanger, a weak igniter or a clogged filter. We also look for corrosion and water marks on furnaces that sit in crawlspaces near the river.

Furnace Repair

We diagnose ignition, blower and control faults and quote the repair before we start. On a furnace that has been through a flood, we check the gas controls and wiring first.

Cooling Services in Chehalis

AC Installation and Replacement

Many older homes here were built without cooling. We add central AC where the ducts can carry it, or ductless systems where they cannot. Explore our AC services.

AC Maintenance

Our spring visit covers the refrigerant charge, outdoor coil, capacitor and condensate drain, so the system starts the cooling season clean.

AC Repair

Water around the indoor unit, a buzzing outdoor unit or warm air from the vents all point to different faults. We find which one you have before quoting a fix.

Heat Pump Services in Chehalis

Heat Pump Installation

About 70 percent of Chehalis homes heat with electricity. A heat pump can cut the electricity needed for heat and adds summer cooling. Learn more about our heat pump services.

Heat Pump Maintenance

Our heat pump visit covers the outdoor coil, drain path, refrigerant charge and defrost controls, which take the most wear in long, wet Chehalis winters.

Heat Pump Repair

When a heat pump ices over, blows cool air or will not switch modes, we test the defrost controls, reversing valve and refrigerant charge.

Why Flood History Affects HVAC Systems in Chehalis

The Chehalis River has a long flood history. A Washington State Transportation Commission briefing on the Chehalis Basin notes that floods closed Interstate 5 in 1990, 1996, 2007 and 2009, and that the five largest floods in the basin have come since 1986.

Floodwater is hard on heating equipment. Furnaces, air handlers and ducts often sit in crawlspaces and garages, the first places water reaches. Gas valves, control boards and blower motors that sit in water can fail later, even if the system seems to restart.

Ducts that held water can also trap silt and moisture. Over time that leads to musty air and mold growth in the duct system, which then blows into every room. Ductwork that sat in floodwater is a judgment call. Some runs can be cleaned and sealed, while soaked insulation and flex duct usually need to be replaced.

If your home has taken on water, have the system inspected before you rely on it for winter heat. Gas valves and controls that have been under water should be replaced, not reused, and equipment set above past flood levels is less exposed the next time the river rises. Tell us about any flood history when you schedule an inspection so we can check the equipment and ducts for water damage.

Chehalis HVAC Questions

Answers to common heating and cooling questions from Chehalis homeowners.

Do you serve homes throughout Chehalis?

Yes. We serve homes across Chehalis, from the older neighborhoods near downtown to homes outside the city limits. We also serve nearby Centralia and Rochester.

My furnace was in a flood. Is it safe to use?

Do not run a gas furnace that has been under water until it has been inspected. Water can damage gas valves, controls and wiring in ways that are not visible. We inspect the system and replace water-damaged parts before it goes back into service.

What if my Chehalis home loses heat after a storm?

If the power is back but the heat is not, check the breaker and the thermostat first. If water reached the furnace or air handler, leave it off and request an inspection. If you smell gas, leave the house and call your gas utility.

How much does it cost to replace a furnace in Chehalis?

The cost depends on the size of the home, the type of system and the condition of the ducts. We quote each option upfront before any work starts, and we can point you to rebates that may apply.

Can you add cooling to an older Chehalis home?

Usually, yes. If the home has ducts in good shape, central AC or a ducted heat pump can use them. If not, a ductless heat pump adds heating and cooling without opening walls.
