Helping you prepare for the changing seasons


It’s best to get your heating and cooling system tuned up in the spring and fall so that you can be prepared for the harsher temperatures the winter and summer bring. During your HVAC maintenance appointment, we’ll:

  • Verify operation of the system prior to conducting preventative maintenance
  • Verify all electrical equipment is within operating specs as needed
  • Clean flame sensors
  • Verify and adjust gas pressures to operating specs as needed
  • Fill the boiler system to operating pressure as needed
  • Inspect the heat exchanger
  • Inspect wiring
  • Inspect control boards
  • Test and inspect thermostats if accessible
  • And much more!


We’ll keep your heating and cooling system working smoothly for as long as possible. Reach out to us to schedule your preventive HVAC maintenance.
