Heating and Cooling System Maintenance

Heating and Cooling System Maintenance

Regular HVAC preventative maintenance is the best way to ensure trouble-free operation and peak performance. Preseason maintenance is important. It can help to avoid a system failure in severe weather when you need it most, and it can also keep your energy bill from getting out of control.

When Should I Do Furnace Maintenance?

We’ve all heard: an ounce of prevention is worth a pound of cure. You’ll find our Preventative Maintenance Checklist, which is a proven method to keep your system running and your home comfortable.

  • For a system that both heats and cools: perform maintenance in the spring and fall
  • For cooling system maintenance only: perform maintenance at least once a year, before the cooling season
  • For furnace maintenance only: perform maintenance at least once a year, before the heating season.

We provide priority service for customers who have an annual maintenance or service agreement.
Bi-annual preventative maintenance will ensure that your system runs as efficiently as possible. SDair will perform the following tasks, depending on the unit:

Outdoor Units

  • Inspect unit for proper refrigerant level and adjust if necessary
  • Clean dirt, leaves and debris from cabinet
  • Inspect condensate pan for restricted drain openings
  • Inspect coil and cabinet
  • Inspect fan motor and fan blades for wear and damage
  • Inspect control box, associated controls/accessories, wiring and connections. Controls may include contactors, relays, circuit boards, capacitors and other accessories. All control box and electrical parts should be checked for wear or damage.
  • Inspect compressor and associated tubing for damage

Indoor Units

  • Inspect and clean blower assembly (includes blower housing, blower wheel and motor)
  • On some models, lubricate motor and inspect and replace fan belt if needed
  • Check combustion blower housing for debris and clean as necessary
  • Inspect evaporator coil, drain pan and condensate drain lines. Clean as needed
  • Inspect for gas leaks in gas furnaces
  • Inspect burner assembly
  • Inspect ignition system and safety controls
  • Inspect heat exchanger or heating elements
  • Inspect flue — check proper attachment, any dislocated sections and for signs of corrosion.
  • Inspect control box, associated controls, wiring and connections
  • Clean or replace air filter
  • Inspect airflow (ductwork)

We recommend that all maintenance and service work be performed by a professional air conditioning and heating dealer that holds the appropriate credentials to install and service air conditioning and heating equipment.
