Western Washington summers have been getting warmer, and a dependable air conditioning system has become essential for home comfort. At Treat's Heating & Cooling, we provide comprehensive AC services including emergency repairs, new system installations, and preventive maintenance for homeowners across the region. With over 53 years of experience and NATE-certified technicians on staff, we have the expertise to work on all major brands and system types. Whether your existing AC has stopped blowing cold air or you are ready to install central air conditioning for the first time, our team will deliver the professional results you expect.

AC Repair & Troubleshooting

When your air conditioner breaks down on a hot summer day, you need fast, reliable service. Our technicians respond promptly and arrive fully equipped to diagnose and resolve the most common AC problems, including refrigerant leaks, compressor failures, fan motor issues, frozen evaporator coils, faulty capacitors and contactors, thermostat malfunctions, and clogged condensate drain lines. We provide upfront pricing before starting any work, so there are never surprises on your bill. Most repairs can be completed in a single visit, getting your home back to a comfortable temperature as quickly as possible.

New AC Installation & System Upgrades

Whether you are adding air conditioning to a home that has never had it or replacing an aging system that is no longer efficient, our installation team will design a cooling solution tailored to your home and budget. As an authorized Carrier dealer, we offer a full range of central air conditioning systems with SEER2 efficiency ratings that can significantly reduce your cooling costs compared to older units. Every installation starts with a detailed load calculation to ensure proper sizing, followed by expert installation that meets or exceeds manufacturer specifications and local building codes. We also evaluate your existing ductwork for leaks, restrictions, or design issues that could affect the performance of your new system.

Seasonal AC Tune-Ups

Scheduling an annual AC tune-up before the cooling season is one of the best investments you can make in your comfort system. During a tune-up, our technicians clean the indoor evaporator coil and outdoor condenser coil, check refrigerant charge and test for leaks, inspect and tighten all electrical connections, lubricate moving parts, test the thermostat for accuracy, clear the condensate drain to prevent water damage, and measure airflow and system performance. A well-maintained AC system uses less energy, provides more consistent cooling, and is far less likely to experience a mid-season breakdown. Our Preferred Customer maintenance plans include annual AC and heating tune-ups along with priority scheduling and repair discounts.

Energy Efficiency & Cost Savings

Modern air conditioning systems are dramatically more efficient than units manufactured even a decade ago. If your current AC has a SEER rating of 10 or less, upgrading to a new system with a SEER2 rating of 15 or higher could reduce your cooling energy costs by 30 to 50 percent. We help homeowners navigate available utility rebates and federal tax credits that can offset the cost of a new, energy-efficient system. Our team will walk you through the options, explain the long-term cost savings, and help you choose a system that balances upfront cost with ongoing efficiency.
