Heating Maintenance

 Preventative Service That Keeps You Warm All Winter 

A Quick Tune-Up Now Can Prevent a Big Problem Later

Annual heating maintenance helps your system run safely, efficiently, and reliably — especially when temperatures drop below freezing. At CRS Heating and Air Conditioning, Inc., we offer thorough seasonal inspections that help prevent surprise breakdowns and extend the life of your system.


Whether you have a furnace, boiler, or heat pump, we’ll make sure it’s ready to handle the cold.

What’s Included in a Heating Tune-Up

We tailor each visit to the system type, but a typical CRS heating maintenance includes:

  • Inspecting heat exchanger or combustion chamber
     
  • Checking blower motor and capacitor
     
  • Testing flame sensor, ignitor, and burners
     
  • Confirming thermostat response
     
  • Inspecting gas valve operation and exhaust flow
     
  • Checking system startup, cycle timing, and airflow
     
  • Tightening connections and inspecting safeties
     
  • Filter check and change (if customer supplies one)
     
  • Boiler-specific: water level, expansion tank, pressure, relief valve
     
  • Heat pump-specific: mode switching, defrost cycle, refrigerant pressures

Why Schedule Maintenance Every Fall?

Even if your system seems to be working fine, problems can build up quietly: dirty burners, weak flame sensors, worn parts, airflow restrictions. A seasonal tune-up helps catch these issues before they become expensive emergencies.


We also check safety components — like limit switches, flue drafts, and gas connections — to help protect your home and your family.
