Maintenance Checklist

Maintaining your equipment can prevent future problems and unwanted expenses. To keep your cooling and heating system at peak performance, have a contractor do annual pre-season check-ups. Contactors usually stay busy during summer and winter so, the best idea is to check the cooling system in the spring and the heating system in the fall. Remember that, ideally, you should plan the check-ups around the time changes in the spring and fall.

A Typical Maintenance Check-up Should Include The Following.

  • Check Thermostat Settings

It ensures that your cooling and heating system provides you comfort when you are home. And, it also saves energy when you are away.

  • Tighten All Electrical Connections

This is to measure voltage and current on motors. The operation of your system can become unsafe because of faulty electrical connections and as a result, the life of major components can reduce.

  • Lubricate All Moving Parts

Friction in motors and increase in electricity consumption is caused by parts with less lubrication.

  • Check And Inspect The Condensate Drain

This action should be performed on your central air conditioner, furnace, and/or heat pump (when in cooling mode). A plugged drain can lead to damage in the house and affect indoor humidity levels.

  • Check Controls of The System

This ensures proper and safe operation. Checking the starting cycle of the equipment can assure that the system starts, operates, and shuts off properly.

Cooling Specific

  • Clean Evaporator and Condenser Air Conditioning Coils

Reduction in the system’s ability to cool your home is caused by dirty coils. This also causes the system to run longer, increases energy costs and reduces the life of the equipment.

  • Check Your Central Air Conditioner’s Refrigerant Level

This should be checked and adjusted if necessary. The efficiency of your system can be reduced due to an increase in energy costs and a reduction in the life of the equipment caused by too much or too little refrigerant.

  • Clean And Adjust Blower Components To Provide Proper System Airflow For Greater Comfort Levels

Airflow problems can lead your system to become 15 percent less efficient.

Heating Specific

  • Check All Gas (or Oil) Connections, Gas Pressure, Burner Combustion, and Heat Exchanger

Improperly operating gas (or oil) connections are termed as a fire hazard and they can contribute to health problems. Improper burner operation is caused by a dirty burner or cracked heat exchanger. Either can be the cause of less safe and less efficient operation of the equipment.

Actions To Yourself

  • Inspect, Clean, or Change Air Filter

This action should be performed once a month in your central air conditioner, furnace, and/or heat pump. You can learn from your contractor how to do this. An increase in energy costs and damage to your equipment can be caused by a dirty filter and it can lead to early failure.
