Furnace, heat pump and boiler service

Whether your heat quit overnight or your system just isn't keeping up, we'll find the cause and fix it. We service gas, electric and oil furnaces, heat pumps and boilers, and we're happy to work on equipment another company installed.

Air conditioning and heat pumps

A heat pump can replace both your furnace and your air conditioner with one efficient system, and it's an upgrade worth asking about. We also install and repair central air and ductless systems, sized correctly for your home so it stays comfortable without wasting energy.

New system installation

When it's time for a new furnace, heat pump or air conditioner, our comfort specialist will look at your home, talk through your options and recommend the right high-efficiency Trane equipment. Our installers take care of everything from removing the old unit to testing the new one. Ask about financing through Salal Credit Union.

Maintenance plans

An annual tune-up is the easiest way to avoid a mid-winter breakdown. We clean and inspect your system, check that it's running safely and let you know about anything that needs attention. A preventative maintenance plan keeps you on schedule every year.
