**NEW** Preventative Maintenance Agreements Available now!

Benefits of a Preventative Maintenance Agreement:

  • Testing thermostat functions can improve comfort and energy costs.
  • Starting the system will verify the system is operational before maintenance.
  • Cleaning/replacing the filter can prevent restrictions that can waste energy and reduce motor/compressor life.
  • Checking the condensate drain, drain pan, and drain fittings can prevent expensive water damage from clogged drains or cracked pans/fittings.
  • Inspecting/cleaning the blower wheel/motor can prevent dirt that can restrict airflow, increase energy costs, and cause premature failures.
  • Inspecting/cleaning the evaporator coil can prevent dirt that restricts airflow, decreases efficiency, and can lead to compressor failure.
  • Inspecting the electric heat operation. If not working, it may reduce comfort and efficiency.
  • Inspecting parts for visible wear can avoid costly emergency service calls.
  • Inspecting electrical connections can ensure safety and extend the life of the system.
  • Checking disconnect switches can find worn fuses or breakers that can overheat and cause safety issues and costly emergency service calls.
  • Cleaning the condenser coil regularly will remove dirt that increases pressures in the system, can cause higher energy costs, and can cause compressor damage.
  • Checking condenser motor amps. For peak performance.
  • Checking condenser fan blades can find faults before damage occurs to unit.
  • Checking compressor and fan capacitors can protect equipment and avoid costly emergency service calls.
  • Checking relays and contactors for any worn/loose connections that can lead to motor/system failure.
  • Checking defrost operations and components can prevent loss of heat and shortened compressor life.
  • Checking operating pressures with gauges ensures optimum performance.
  • Explaining maintenance results to the customer so they better understand.
  • Advising customers of needed improvements allows the customer to understand the efficiency and make decisions about current and future repair costs and planning.
  • At the end of the preventative maintenance any questions can be answered and the next preventative maintenance can be scheduled.
