Home Comfort Alliance repairs and installs central air conditioning, heat pumps and ductless mini-splits for Kenmore homes. Our Redmond branch covers the city; call (425) 645-0404 or send the form, and a comfort advisor will set up the visit. Estimates for new systems are free.
Kenmore’s summers are usually mild and dry, but not always. In the late-June 2021 heat dome, many homes around the north end of Lake Washington had no way to cool down.
Published estimates, not our prices:
| Work | Range | Source |
|---|---|---|
| HVAC or AC repair | About $350 on average; $100 to $3,000 | Angi, HVAC repair costs, 2026 data |
| New central air, Seattle area | $5,098 to $9,785, averaging $7,377 | Angi, Seattle AC replacement costs, updated August 2026 |
| Ducted heat pump, Seattle area | $3,160 to $20,000 depending on efficiency | Angi, Seattle heat pump installation costs, updated July 2026 |
| Single-zone ductless | $2,222 to $5,555 | Angi, Seattle mini-split costs, 2026 data |
The main variables are existing ductwork, the wiring for the outdoor unit, how many rooms or zones need cooling, and the efficiency you choose.
Kenmore wraps around the north end of Lake Washington, so many homes face south toward the water, with big windows catching the afternoon sun. Those rooms can be several degrees warmer than the rest of the house. Good design accounts for it: a room-by-room load calculation that counts glass and orientation, more airflow or a dedicated ductless head for the sunniest rooms, and practical steps such as exterior shades or solar-control window film that cut the load before the equipment has to handle it.
In Kenmore, the choice often comes down to how you heat:
| You heat with | Cooling option | PSE rebate |
|---|---|---|
| Electric baseboards or wall heaters | Ductless heat pump in main rooms | $1,500, plus up to $2,400 with Efficiency Boost |
| Electric furnace | Ducted heat pump with air handler | $1,500, plus up to $2,400 with Efficiency Boost |
| PSE gas furnace | Heat pump for dual fuel, or central AC | Dual fuel: $1,500, plus up to $2,400 |
| Anything, one hot room | Single-zone ductless | Depends on the heat it replaces |
Sources: PSE electric resistance to heat pump rebate; PSE hybrid heat pump rebate. A cooling-only AC does not qualify for these rebates; a heat pump does, and it heats efficiently all winter too. More on our Kenmore heat pump page.
Most summer calls fall into a handful of patterns:
Before calling, confirm the thermostat is set to cool below room temperature, change a dirty filter, and check both breakers. If the lines are iced, turn cooling off and run the fan to thaw them.
Kenmore’s newer townhomes along Bothell Way and near downtown often have little room for an outdoor unit, close neighbors and association rules. Compact and variable-speed units are quieter and easier to place; wall brackets can lift a unit off a narrow side yard; and line sets can run in covers painted to match. Bring your association’s guidelines to the estimate and we will design around them.
A few habits make a noticeable difference on the PSE bill in summer. Close blinds on south- and west-facing windows during the afternoon, especially in lake-view rooms. Set the thermostat a few degrees higher when nobody is home instead of switching the system off, so it is not fighting a hot house at dinnertime. Use ceiling fans in occupied rooms to feel cooler at a higher setting. Keep the outdoor unit clear of plants and debris, and change filters on schedule so the system is not working against a clogged filter.
During late-summer wildfire smoke, the house stays closed and the cooling system does double duty. A MERV 13 filter, where the blower allows, cleans the air in ducted systems; in homes with ductless heads, a portable HEPA purifier in the main room adds filtration.
A spring tune-up before the first warm stretch covers cleaning the outdoor coil and clearing debris, testing the capacitor, contactor and fan motor, checking refrigerant pressures and the temperature drop across the coil, flushing the condensate drain, and on heat pumps, checking the reversing valve and defrost controls. Pollen, leaves and seed fluff can mat the outdoor coil in late spring, so a mid-season rinse with a garden hose (power off, gentle pressure, from the inside out where possible) keeps the unit breathing freely through the hottest weeks.
Three decisions shape how a new system will feel and what it will cost to run:
We quote more than one option on request, with the running cost difference explained.
The crew protects floors and walkways, sets the outdoor unit on a level pad or bracket, runs the refrigerant lines and pressure-tests them, then pulls a deep vacuum to clear moisture before releasing refrigerant. The electrician wires the disconnect and controls, and the condensate line is routed to a drain. Before leaving, the installer confirms charge and airflow, sets up the thermostat or remotes with you, shows you the filters, and leaves the equipment and permit paperwork. The city and L&I inspections follow.
New cooling equipment in Kenmore needs a City of Kenmore mechanical permit (City of Kenmore, Do I Need a Permit?), and the circuit for the outdoor unit needs an L&I electrical permit (L&I, cities that do their own electrical permits). We file both and schedule inspections.
We support the manufacturer’s warranty on covered equipment parts, and we stand behind our air conditioning and heat pump 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.
National data puts HVAC repairs around $350 on average, with a range of about $100 to $3,000 (Angi, 2026). We give a written price after diagnosis.
Not for cooling-only AC. A heat pump that replaces electric heat, or pairs with a PSE gas furnace, can qualify for PSE rebates of $1,500 plus up to $2,400.
Yes, with a ductless mini-split. Each room or zone gets its own head and control.
Yes: a City of Kenmore mechanical permit and an L&I electrical permit. We handle both.
Large south-facing windows admit a lot of afternoon sun. Extra airflow, a ductless head or window treatments address it.
Usually one to two days for a single system.
For most homes, yes. It runs quieter and longer at low speed, removes more humidity and keeps temperatures steadier than a single-stage unit.
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 Redmond-based comfort advisor will measure your home and give you written options, PSE rebate help and financing choices.
