Heat Pump Services

The Smart Choice for Pacific Northwest Comfort

Heat pumps have become the most popular heating and cooling option in Western Washington, and for good reason. They provide efficient year-round comfort by transferring heat rather than burning fuel, making them one of the most environmentally friendly and cost-effective HVAC options available. At Treat's Heating & Cooling, we have been installing, repairing, and maintaining heat pump systems throughout the region for decades. Our NATE-certified technicians are experts in all types of heat pump technology, from conventional air-source systems to advanced cold-climate models and ductless configurations. We will help you choose the right system for your home, install it to the highest standards, and keep it running efficiently for years to come.

How Heat Pumps Work in the Pacific Northwest

A heat pump operates on a simple but powerful principle: it moves heat from one place to another using a refrigerant cycle. In winter, the system extracts heat energy from the outdoor air and transfers it inside. Even when outdoor temperatures feel cold, there is still significant thermal energy in the air that a heat pump can capture. In summer, the process reverses, and the heat pump removes heat from your home and releases it outdoors, just like a conventional air conditioner. Western Washington's mild climate, with winter temperatures that rarely drop below the mid-20s, makes our region one of the best environments for heat pump performance. Modern cold-climate heat pumps can maintain full heating capacity at temperatures well below zero, providing reliable warmth even during our occasional cold snaps.

Types of Heat Pumps We Install

We offer a full range of heat pump systems to suit every home and budget. Air-source heat pumps are the most common type, using an outdoor unit and an indoor air handler connected by refrigerant lines to provide whole-home heating and cooling through your existing ductwork. Ductless mini-split heat pumps are ideal for homes without ductwork, additions, or rooms that are difficult to condition with a central system. They provide zone-by-zone temperature control and can be installed with minimal disruption. Dual-fuel hybrid systems pair a heat pump with a gas furnace, automatically switching between electric heat pump operation and gas furnace backup depending on which is most efficient at the current outdoor temperature. This approach is popular with homeowners who want the efficiency of a heat pump with the assurance of a gas backup for the coldest days of winter.

Rebates, Tax Credits & Energy Savings

Installing a heat pump can qualify you for substantial financial incentives. The federal Inflation Reduction Act provides tax credits of up to $2,000 for qualifying heat pump installations. Washington state and local utilities such as Puget Sound Energy also offer rebates that can further reduce your out-of-pocket costs. Combined with the ongoing energy savings from operating a heat pump instead of a gas furnace and separate air conditioner, many homeowners find that their new system pays for itself within five to eight years. Our team stays current on all available incentives and will help you identify every rebate and credit you are eligible for.

Heat Pump Repair & Maintenance

Because a heat pump operates year-round, regular maintenance is essential to keep it running efficiently and reliably. Our comprehensive heat pump tune-up includes cleaning the indoor and outdoor coils, checking refrigerant charge and testing for leaks, inspecting and testing the reversing valve, verifying the defrost cycle operates correctly, testing electrical components and connections, and checking the backup heat source if applicable. If your heat pump needs repair, our technicians can diagnose and fix common issues including refrigerant leaks, compressor problems, defrost cycle failures, fan motor issues, and thermostat malfunctions. We stock parts for all major brands and can complete most repairs in a single visit.
