Repair or replace?
A repair is usually the better value when the system is younger and has a single fault. Replacement starts to make sense when:
- The system is past about 15 years old and needs a major repair, such as a compressor or heat exchanger.
- An air conditioner or heat pump uses R-22 refrigerant, which is no longer made.
- Repairs are coming every season, or some rooms never get comfortable.
- You want to switch from oil, gas or electric resistance heat to a heat pump and use a utility rebate.
Our technician gives you repair and replacement options with upfront prices, so you can compare (HVAC replacement).
HVAC rebates by utility
Most Puget Sound rebates in 2026 are for heat pumps, not cooling-only air conditioners, and the federal 25C tax credit ended for equipment installed after 31 December 2025. Your rebate depends on your utility:
| Your utility | Where to read the current amounts |
|---|---|
| Puget Sound Energy (PSE) | PSE rebates |
| Seattle City Light | Seattle City Light rebates |
| Tacoma Power | Tacoma Power rebates |
| Snohomish PUD | Snohomish PUD rebates |
| Bellevue, Kirkland, Redmond and other Eastside cities | Energy Smart Eastside |
We submit the rebate paperwork for PSE, Tacoma Power and Cascade Natural Gas rebates, and we are a Seattle Clean Heat participating contractor. All programs: rebates.
How a new system is installed
- Free in-home estimate. A comfort advisor looks at your equipment, ducts, electrical panel and where new equipment can go.
- Load calculation. We run an ACCA Manual J load calculation so the system fits your home.
- Written options. You get upfront prices for each option and the rebates it qualifies for.
- Permits. We pull the required permits.
- Installation. Most furnace and heat pump installations take between 4 and 10 hours, depending on the system type and how many systems we install.

New installations come with a 3-year Comfort Shield labor warranty, kept active with yearly maintenance, and first-year maintenance is included. Home Comfort Club members with a new system installed by Home Comfort Alliance get extended labor coverage for up to 5 years from installation. We also support the manufacturer's warranty on covered parts.
A recent heat pump installation in Graham
In September 2026 our crew installed a complete 3-ton heat pump system in a Graham home: a new outdoor heat pump, a matching indoor air handler, a Wi-Fi thermostat, a media air cleaner for better filtration and a surge protection device for the outdoor unit. The crew ran the electrical, control wiring, condensate drain and refrigerant line connections, then started the system and tested airflow, refrigerant performance, the thermostat and both heating and cooling before handing it over.
