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.
These are regional estimates from Seattle-area data. Olympia-specific surveys aren’t published, and your quote is written after we find the fault.
| Repair | Typical range |
|---|---|
| Furnace repair, most jobs | $139 to $544 (about $341 typical) |
| Full range seen | $97 to $2,000 |
| Flame sensor | $160 to $270 |
| Blower motor | $160 to $2,160 |
| Heat exchanger | $110 to $1,620 |

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.
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.
| 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 |
When replacement makes sense, compare furnace replacement in Olympia with heat pump installation in Olympia. Replacement estimates are free.
Because Olympia homes can have PSE gas and PSE electric service, all three common setups are on the table:
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).
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 heat exchanger 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.
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 appliance we service gets a combustion and carbon monoxide check before we leave.
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 the labor warranty on repairs is extended for as long as your prepaid membership runs, 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.
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.
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.
Yes. The City of Olympia requires a permit for furnace and gas appliance replacement. We pull it and schedule the inspection.
Once a year, ideally in early fall before the heating season. Heat pumps that also cool benefit from a spring check as well.
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) get the labor warranty on repairs extended for as long as their prepaid membership runs, up to 5 years from installation.
A Sumner-based comfort advisor will set up a visit and give you repair and replacement options in writing, with PSE rebates and financing.
