AC Repair Portland: $172 to $664 + Heat Wave Steps (2026)

AC-specific rows are national; the Portland row covers all HVAC repairs.

Do this now: AC out during Portland heat

1. Check the thermostat is on cool and set below room temperature, and check the breaker.
2. Replace a dirty filter. Lennox says a dirty filter restricts airflow, a common cause of a frozen coil.
3. Ice on the indoor coil or the copper line: Bryant says switch the thermostat from Cool to Off, do not chip the ice, and do not restart until it has thawed, which can take hours.
4. Move older adults, babies and anyone with heart or lung disease to the coolest room or a cooling center; call 311 for locations.
5. Power out? Report it to PGE at 503-464-7777.

Is it urgent? When a Portland AC failure is an emergency

A dead AC is an emergency in Portland when a heat wave is on and someone in the home is old, very young or ill. Portland is mild most summers, averaging 14.6 days a year at or above 90 F and 1.3 days at or above 100 F at the airport, NOAA's normals show, so many homes were built without central air. That gap is what made the June 2021 heat dome so deadly: the City of Portland says it claimed nearly 100 lives in Oregon, 72 in Multnomah County. In mild weather, a slow-cooling AC can wait for a weekday visit; see AC not cooling for checks.

Cooling Portland: free portable heat pumps

The City's Cooling Portland program, paid for by the Portland Clean Energy Community Benefits Fund, delivered and installed more than 20,500 portable heat pump cooling units for low-income, heat-vulnerable Portlanders in its first four years, the City said on May 1, 2026, with a goal of 25,000. This is its fifth and final year; 2026 applications ran through June 30, 2026. Call 311 to ask what is still available.

Common AC repairs and what they cost

Most AC repairs are small parts. HomeGuide's table puts a capacitor at $100 to $250, and HomeAdvisor puts a refrigerant leak repair at $225 to $1,600 and a compressor replacement at $1,200 to $2,800. If the compressor fails on an older unit, price a replacement too: ConsumerAffairs lists a full Portland HVAC system at $7,100 to $14,200. National prices are on AC repair and AC replacement cost.

Permits and incentives if the AC needs replacing

Replacing an AC condenser, heat pump or mini-split in Portland needs a mechanical permit even when no building permit is needed, and most jobs also need an electrical permit, Portland Permitting and Development says. Energy Trust of Oregon pays $800 for a ductless heat pump ($1,800 for income-qualified or rental homes) and $1,000 for a ducted heat pump replacing an electric furnace. A heat pump cools and heats, so compare it with a plain AC on heat pump installation cost and mini split installation.

Questions to ask a Portland AC company

1. What is your CCB number?
2. What is the diagnostic fee? ConsumerAffairs lists $90 to $175 in Portland.
3. What refrigerant does my system use, and is it leaking?
4. If replacement makes more sense, will you price a heat pump and pull the permits?
