Furnace & Heating Services

Complete Heating Solutions for Western Washington Homes

When the cold Pacific Northwest winters set in, a reliable heating system is not a luxury. It's a necessity. At Treat's Heating & Cooling, we have been providing professional furnace and heating services to families across Western Washington since 1973. Our NATE-certified technicians are trained to work on all types of heating systems, including gas furnaces and electric furnaces. Whether you need an emergency repair, a complete system installation for a new home, or routine seasonal maintenance, our team is ready to deliver fast, dependable service backed by decades of hands-on experience.

Furnace Repair & Diagnostics

A furnace breakdown in the middle of winter can be stressful and even dangerous, especially for families with young children or elderly members. That is why we offer prompt furnace repair service throughout our service area. Our technicians arrive equipped with diagnostic tools and a full inventory of common replacement parts, allowing us to resolve most issues in a single visit. We diagnose and repair problems including failed ignitors and flame sensors, blower motor failures, cracked heat exchangers, faulty thermostats and control boards, clogged filters and restricted airflow, gas valve and pilot light issues, and unusual noises or odors. We charge by the job rather than by the hour, so you know exactly what the repair will cost before we begin any work.

New Furnace Installation & Replacement

If your current furnace is aging, inefficient, or beyond cost-effective repair, upgrading to a new high-efficiency system can be one of the smartest investments you make in your home. Modern furnaces achieve Annual Fuel Utilization Efficiency ratings of 95 percent or higher, meaning that 95 cents of every dollar you spend on fuel goes directly toward heating your home. Compare that to older systems that may operate at 60 to 80 percent efficiency, and the long-term savings become significant. As an authorized Carrier dealer, we offer a full line of premium furnaces along with other leading brands. Every installation begins with a thorough load calculation to ensure your new system is properly sized for your home, maximizing comfort and efficiency.

Annual Heating Maintenance

Preventive maintenance is the single most effective way to extend the life of your furnace and avoid unexpected breakdowns. Our comprehensive heating tune-up includes a thorough inspection and cleaning of all major components, calibration of the thermostat, testing of safety switches and controls, inspection of the flue and venting for proper draft, and a full system performance test. Regular maintenance not only keeps your system running reliably but also maintains your manufacturer's warranty coverage and helps keep your energy bills as low as possible. Ask about our Preferred Customer maintenance plans, which include annual tune-ups, priority scheduling, and discounts on parts and repairs.
