Problems We Solve

  • Hot bedrooms and uneven cooling
  • Noisy or failing outdoor units
  • Systems that run constantly but still don’t keep up
  • Sticker shock from repeat repair bills

Our Approach

  • Correctly size your AC based on your home and existing ductwork.
  • Use union-trained installers to protect warranty and efficiency.
  • Set up controls and airflow so comfort is even across your home.
  • Offer quarterly maintenance to keep it clean, efficient, and reliable.

AC Installation, Replacement and Repair in Snohomish and King County


We install new central air conditioning, replace aging AC units and handle AC repair for homes across Snohomish County and King County. If your air conditioning needs replacement, we start with a load calculation so the new system fits the house, and if it only needs repair, you get a written price before any work begins. As a Snohomish air conditioning company since 1968, we also install heat pumps, which cool in summer and heat in winter from a single system.
