Air Conditioning Services Greater Puget Sound

We recommend scheduling professional A/C maintenance once a year, ideally in early spring before the summer heat arrives. Regular tune-ups keep your system running at peak efficiency, extend its lifespan, and prevent sudden breakdowns.

Common warning signs include warm air blowing from vents, unusual noises (grinding or squealing), strange odors, weak airflow, frequent system cycling, high utility bills, or water leaking around the indoor unit.

With regular maintenance, a modern air conditioning system typically lasts between 12 to 15 years. If your unit is over 10–12 years old and requires frequent or costly repairs, replacement is often more cost-effective.

Our tune-up includes deep cleaning key components, checking refrigerant levels, inspecting and tightening electrical connections, calibrating the thermostat, inspecting the drain line, and verifying overall system safety. Plus, it’s backed by our 6-Month No Breakdown Guarantee!

If your system is less than 10 years old and repair costs are reasonable, repairing is usually the best choice. However, if repair costs exceed 50% of a new system’s value or your unit uses obsolete refrigerant (R-22), upgrading to an energy-efficient system will save you money in the long run.

A standard residential air conditioner replacement usually takes 4 to 8 hours to complete. Our certified technicians complete most installations in a single day with minimal disruption to your home.

Change your air filters every 1 to 3 months, keep the area around your outdoor condenser unit clear of debris and plants, seal air leaks around doors and windows, and use a programmable or smart thermostat.
