Q&A

Why is proper HVAC sizing so important for homes in Port Angeles?

Port Angeles homes have unique heating needs due to our coastal climate and varied home ages. An oversized system will short-cycle, wasting energy and failing to dehumidify properly, while an undersized one will struggle in colder snaps. Our technicians perform detailed Manual J load calculations, factoring in your home's insulation, windows, and layout to recommend a system that provides consistent comfort and efficiency year-round.

How can I protect my outdoor AC or heat pump unit from corrosion in our rainy climate?

The constant moisture and salt air here accelerate corrosion. We recommend and install units with corrosion-resistant coatings on coils and cabinets. During our seasonal maintenance visits, we clean the unit thoroughly to remove debris that traps moisture, check for early signs of rust, and apply protective treatments when necessary. Proper installation with adequate clearance from vegetation and drainage also significantly extends your unit's lifespan.

What are the signs my current HVAC system might be improperly sized for my home?

Common signs include uneven temperatures from room to room, the system constantly turning on and off (short-cycling), excessively high energy bills, and difficulty maintaining a set temperature during typical Port Angeles weather. If you're experiencing these issues, our team can perform an assessment and load calculation to determine if your system is the correct size or if an upgrade would improve your comfort and savings.
