HVAC maintenance plans and agreements
Heating and cooling systems have a way of breaking down at the worst possible times: on the coldest day of winter or during a sizzling summer heat wave. This is when your home comfort system has to work the hardest and when you need it most.
With Watts, you don’t have to worry! Choose one of our HVAC maintenance plans and you’ll never strike out on a maintenance or repair bill again!

Frequently Asked Questions
What does preventative maintenance include?
Our HVAC maintenance services include but are not limited to: testing safety controls, cleaning condenser coil and condensate drains, inspecting the filtration system, checking for refrigerant leaks, tightening electrical connections, and calibrating the thermostat.
If my HVAC unit needs to be repaired, is that a separate visit?
A: Our qualified technicians will evaluate the service needed, and if extra time or additional parts to complete the work are required, we will work with you to find a convenient time to do so.
Are your HVAC techs certified?
A: Yes! All of our installers and technicians are trained on a regular, on-going basis. Watts has been certified by the following industry organizations: Bryant Factory Authorized Dealer, North American Technician Excellence, ORACCA, AGC, The Oregon Mechanical Officials Association, and The Northwest College of Construction.
Does regular HVAC maintenance save me money and make my unit last longer?
Routine tune-ups prevent costly, major breakdowns and keep your system running efficiently, which helps lower your monthly utility bills. It can also extend the lifetime usage of your unit.
What kind of HVAC maintenance should I do on my own?
You can save money and prevent system breakdowns by handling basic, user-friendly tasks yourself. Focus your DIY maintenance on changing air filters, cleaning vents and registers, clearing the drain line, and maintaining clearance around your outdoor unit. It is generally recommended to hire a licensed HVAC technician for annual, comprehensive tune-ups to keep things running smoothly. If you are ever unsure of what to do or have questions, the Watts Home Team is here to help!
Are there things I should do to prepare my HVAC unit for seasonal changes?
Replace or clean your air filters every 1-3 months to prevent your system from overworking. Clean debris and leaves away from the exterior unit, maintaining about two feet of clear space around it.
