Keeping cool: It’s a good time to get ready for summer heat

Contactors, like the one pictured, and capacitors are two of the biggest items replaced in HVAC unit maintenance and repairs, Dave Carlson said.

Ensuring your inside coils are free of debris or buildup is key for your HVAC unit to continue running properly as warmer weather approaches.

A can of evaporating no-rinse foam spray is useful for cleaning off the inside coils of an HVAC unit without worrying about damaging any of the electrical units with water.

Dave Carlson opens up a HVAC unit outside the Polhamus office building in Moses Lake on Wednesday to showcase the inside coils and some of the areas they inspect on maintenance jobs this time of year.

Dave Carlson explained the way to know if capacitors like the one pictured have gone had is if they have swelled up badly on top or have oil pooling up around the surface.
