AC Inspection in Seattle

Serving Puget Sound Homeowners Since 1987. NATE Certified. A+ Rated.

Seattle summers don’t give much warning. When a heat wave arrives or wildfire smoke rolls in, your air conditioner needs to perform on demand. An AC inspection is a diagnostic evaluation of your cooling system’s current condition, separate from the recurring tune-ups that make up routine maintenance. It gives you a clear picture of what’s working, what needs attention, and what could fail under pressure. Brennan Heating, Air Conditioning, Plumbing, and Electrical has been serving homeowners across the Puget Sound region since 1987, and our technicians know the systems and conditions that define Western Washington cooling.

What We Check During an AC Inspection

A professional inspection covers components that a homeowner filter swap can’t reach. Our technicians work through the full system during a complete operating cycle, checking each element against expected performance standards.

Here’s what we assess:

• Refrigerant pressure and level: Identifies leaks that stress the compressor and reduce cooling output
• Evaporator and condenser coils: Dirty coils restrict heat exchange and drive up energy costs
• Condensate drain line: Clogs cause water damage and create conditions for mold growth
• Thermostat accuracy and calibration: Confirms the system is responding correctly to temperature settings
• Electrical connections, capacitors, and contactors: Wear or corrosion at these points causes sudden shutdowns
• Blower motor function: Affects airflow throughout the home
• Air filter condition and overall airflow: A restricted filter makes every other component work harder

The result is a detailed assessment of what’s in good shape, what needs near-term attention, and what could be at risk before the next cooling season.

AC Inspection vs. AC Maintenance: Which Do You Need?

These two services solve different problems. An inspection is diagnostic: we evaluate how every component is performing, identify current issues, and flag emerging risks. It’s the right starting point if your system hasn’t been professionally evaluated recently, if you’ve noticed a performance symptom, or if you want more confidence before peak season arrives.

AC maintenance is preventive care. It covers recurring seasonal work, including thermostat calibration, filter replacement or cleaning, electrical connection checks, refrigerant pressure verification, condensate drain clearing, and full system performance testing. Once your system’s baseline is confirmed through an inspection, ongoing maintenance supports that performance. For heat pumps running year-round, twice-yearly service is commonly recommended. We offer a Maintenance Membership with priority scheduling and member perks for homeowners who want that consistency built in.
