Heating repair and service in Olympia, WA
Home Comfort Alliance repairs, maintains and replaces gas furnaces, electric furnaces, heat pumps and ductless systems in Olympia, with technicians sent from our Sumner branch. We diagnose first, explain what failed and why, and give you a written price before any repair.
Olympia’s heating season is long rather than harsh. Olympia winters are cool and very wet, so systems run for months in damp weather instead of short bursts of extreme cold. That steady use wears out igniters, blower motors and filters, and it makes efficiency count: a system that is 20% less efficient costs you that 20% every month from October to April. Puget Sound Energy supplies both electricity and natural gas here, so homes may heat with gas, electric resistance or a heat pump, and we work on all three.
Quick answer: if your furnace or heat pump isn’t keeping up, is short-cycling or is making new noises, book a diagnostic. If it is 15 or more years old and the repair is major, we will price a replacement next to the repair.

Signs your heating needs attention
- The system runs but the house never reaches the thermostat setting.
- It turns on and off every few minutes (short-cycling).
- Some rooms stay cold while others are fine.
- New noises: squealing, grinding, banging at start-up, or a heat pump that roars and won’t finish defrosting.
- Bills are rising faster than rates.
- A gas furnace flame looks yellow or lazy instead of steady blue.
- A carbon monoxide alarm sounds. Get everyone out, call 911 and PSE from outside, then call us.
Heat pump and ductless repairs
Heat pumps run year-round, so they see more hours than a furnace. The repairs we make most often are failed capacitors and contactors that stop the outdoor unit from starting, defrost controls or sensors that let ice build up on the coil, refrigerant leaks at flare fittings or coils, and thermostats set up so that backup electric heat runs far more than it should. On ductless systems, a flashing error code on the indoor head usually points to a sensor, a communication fault between the indoor and outdoor units, or a clogged condensate line. We test before we replace anything, and we explain whether a leak is worth repairing on an older system or whether the money is better put toward a new one.
Cold rooms and uneven heat
If one bedroom is always colder, the equipment may be fine and the problem is air delivery. Common causes are a crushed or disconnected duct in the crawlspace or attic, closed or blocked registers, too few return air paths, or a blower set to the wrong speed. We measure airflow and static pressure to find the cause. Sealing and reconnecting ducts, adding a return, or rebalancing dampers often fixes the room for far less than new equipment. For a room that was never on the duct system, such as a bonus room or addition, a single ductless head is usually the cleanest fix.
Repair or replace?
| Situation | Usual advice |
|---|---|
| Under 10 years, single part failure | Repair |
| 10 to 15 years, moderate repair | Repair, and start budgeting |
| Over 15 years with a major failure | Price a replacement |
| Cracked heat exchanger | Replace; it is a safety issue |
| Repeated repairs in a short period | Price a replacement |

Gas furnace, heat pump or both
Because Olympia homes can have PSE gas and PSE electric service, all three common setups are on the table:
- High-efficiency gas furnace: reliable heat, no cooling unless paired with AC or a heat pump.
- Heat pump: heating and cooling in one system; a strong fit for Olympia’s mild winters and a real help in heat waves like the one in late June 2021.
- Dual fuel (hybrid): a heat pump that carries most of the season, with the gas furnace as backup on the coldest hours. PSE offers $1,500, plus up to $2,400 through Efficiency Boost, for a qualifying hybrid system in a PSE gas home (PSE hybrid heat pump rebate).
- Electric resistance to heat pump: PSE offers $1,500, plus up to $2,400 through Efficiency Boost, when a heat pump replaces baseboards, wall heaters or an electric furnace (PSE electric resistance to heat pump rebate).
Home Comfort Alliance is a PSE Trade Ally approved contractor for HVAC systems, which PSE requires for these rebates. Thurston County’s Energize Thurston program offers separate discounts through its own participating installers; we are not currently on that list (Energize Thurston, Thurston Climate Collaborative).
Heating maintenance
A yearly tune-up before the heating season catches worn parts while they are cheap to replace. On a gas furnace we clean and test the burners and flame sensor, check the flue and venting, measure gas pressure and temperature rise, test safety switches and replace the filter. On a heat pump we check refrigerant pressures, clean the outdoor coil, test the defrost cycle and backup heat, and tighten electrical connections. Members of our Home Comfort Club get the extended repair labor warranty described below.
What happens on a heating service call
- Booking. Call or use the form at the top of the page; a Sumner-based coordinator confirms a window and the diagnostic fee.
- Diagnosis. The technician checks the thermostat, power, gas supply, filter, igniter or defrost controls, blower and safety switches, and tells you what failed.
- Written price. You get the repair price, and on older systems a replacement price alongside it, before any work starts.
- Repair and test. We fix it, run the system through a full cycle and check combustion or refrigerant readings.
- Follow-up. If parts need ordering, we schedule the return visit before we leave.
Permits and safety
The City of Olympia requires permits for furnace and gas appliance work (City of Olympia, What Do I Need?), and electrical work in Olympia is permitted and inspected by the city itself (L&I, cities that do their own electrical permits). Repairs that replace a like part usually don’t need a permit; replacing equipment does. We pull the permit when one is needed and meet the inspector. Every gas repair we do ends with a carbon monoxide check before we leave.
Warranty and Home Comfort Club
We support the manufacturer’s warranty on covered equipment parts, and we stand behind our heating installations with a 1-year labor warranty from installation.
Join our Home Comfort Club, a monthly membership starting at $15 a month, and a new system we install gets extended labor coverage for as long as your membership stays active, up to 5 years from installation. Ask your technician or comfort advisor for the current plan details.

Seattle-area data puts most furnace repairs between $139 and $544, about $341 on average, with bigger repairs up to around $2,000 (Angi, August 2026). We give a written price after diagnosing the problem.
Is a heat pump a good fit for Olympia?
Yes, for most homes. Olympia’s winters are long but mild, with a December average of 38.4°F, which is the range where heat pumps are most efficient. A gas furnace can stay as backup in a dual-fuel setup.
Are there heating rebates in Olympia?
PSE offers $1,500, plus up to $2,400 through Efficiency Boost, for qualifying heat pumps that replace electric heat or pair with a gas furnace (as of September 2026). Home Comfort Alliance is a PSE Trade Ally approved contractor.
Do I need a permit to replace a furnace in Olympia?
Yes. The City of Olympia requires a permit for furnace and gas appliance replacement. We pull it and schedule the inspection.
How often should I service my furnace or heat pump?
Once a year, ideally in early fall before the heating season. Heat pumps that also cool benefit from a spring check as well.
What warranty comes with your work?
We support the manufacturer’s warranty on covered equipment parts, and our labor warranty covers installations for 1 year from installation. Home Comfort Club members (monthly membership starting at $15 a month) with a new system installed by Home Comfort Alliance get extended labor coverage for as long as their membership stays active, up to 5 years from installation.
