HVAC Maintenance in Seattle

Keeping an HVAC system running reliably and efficiently in Seattle requires more than occasional repairs. Green Head Heating provides comprehensive HVAC maintenance designed for homeowners who want predictable comfort, lower utility bills, and longer equipment life. With Seattle’s cool, damp winters and increasingly variable summers, seasonal tune-ups and a structured maintenance program help protect your system and maintain healthy indoor air quality.

Why HVAC Maintenance Matters in Seattle

Seattle’s climate presents unique challenges that make regular maintenance essential:

  • Persistent humidity accelerates mold, mildew, and corrosion.
  • Coastal neighborhoods expose outdoor units to moisture and salt.
  • Short, intense summer heat waves require cooling systems to perform reliably, despite limited annual use.
  • Heat pumps, widely used in the Pacific Northwest, rely heavily on proper refrigerant levels and defrost performance for winter heating.

Routine maintenance reduces breakdowns, improves energy efficiency, and protects indoor air quality in Seattle’s damp environment.

What a Typical Annual HVAC Tune-Up Includes

A professional annual tune-up covers the essential inspections and tasks required to keep your system safe and efficient.

Electrical Inspections

  • Visual and hands-on checks of wiring, relays, fuses, and contactors
  • Verification of proper amperage and voltage for motors and compressors

Filter Replacement & Assessment

  • Evaluation of current filter condition and type
  • Replacement with the correct MERV-rated filter
  • Recommendations for upgrades when air quality improvements are needed

Refrigerant & Pressure Checks

  • Measurement of refrigerant pressures and temperatures
  • Identification of leaks or inefficiencies that require further repair
  • Ensuring proper charge—critical for both cooling and heat pump performance

Coil Cleaning

  • Cleaning indoor evaporator coils and outdoor condenser coils
  • Removal of debris, pollen, and buildup that restrict airflow
  • Restoring heat transfer efficiency

Lubrication

  • Lubrication of motors, bearings, and moving parts to reduce wear

Thermostat Calibration

  • Ensuring accurate readings and proper communication with the system
  • Adjustments to improve efficiency and comfort

Condensate System Inspection

  • Clearing condensate drains and pans to prevent clogs and mold
  • Testing condensate pumps where applicable

Duct Checks

  • Visual inspection of accessible ducts for leaks, gaps, insulation issues, and contamination
  • Recommendations for sealing or insulation improvements

Every visit includes full documentation so homeowners have a clear record of system condition and maintenance history.

Seasonal Tune-Ups & Recommended Frequency

For most Seattle homes, two tune-ups per year are ideal:

Fall Heating Tune-Up

  • Heat pump reversing valve and defrost operation
  • Gas furnace combustion checks and venting
  • Safety verification before the long cool season

Spring Cooling Tune-Up

  • Refrigerant verification
  • Condenser cleaning after winter
  • Cooling performance testing

Homes with older systems, high usage, or humidity issues may benefit from additional mid-season inspections. Heat pumps, often used year-round, particularly benefit from semi-annual service.

Ryan has the exact experience to make sure you’re getting the climate control that your home needs. His knowledge is extensive and he always has an answer to every question and on top of that he’s pleasant to work with. Ryan and his main tech Tristan have done many high quality HVAC installs that I have seen in the last year and I couldn’t imagine trusting anyone else for the job. Thank you, Greenheads!

Karlan S.

We decided to replace our very old gas furnace with a newer and hopefully quieter furnace.  We contacted Greenhead because they were a smaller, local business.  Everything about the process was excellent.  Best of all the furnace is exceptionally quiet.  Thanks Greenhead.

Bruce R.

Would recommend! Our heat cut out during a cold snap - I called Greenhead the next morning and Ryan was at my house the same afternoon. He quickly diagnosed a faulty switch in our furnace and was back that evening with a new part! Pricing was reasonable, especially given the urgency.

Eamonn K.

I had Greenhead out to do service on my gas furnace and heat pump. Ryan was very professional and helpful. The service was very reasonably priced even though they were there in the evening! I would recommend them to anyone.

Lindsay P.

Came same day when we had no heat. Worked quickly to find the issue while explaining everything he was doing. Really took the time to make us feel like a valued customer not just a number.
