Filter
Check the air filter to ensure it is clean. A dirty filter can restrict airflow and cause excessive wear and tear on your equipment.

NOTE: Before undertaking any examination of your system, be
sure the power is off to any piece of equipment you are examining.

Vents
Many air supply vents have adjustments in the home which can be closed, and in turn, cause air flow issues. The return vents should also be clear of any obstructions like furniture, insulation, paintings, etc. Make sure there is a clear path for air flow for peak efficiency.

NOTE: Before undertaking any examination of your system, be
sure the power is off to any piece of equipment you are examining.

Batteries
Some thermostats require batteries for proper operation. Check the batteries by removing the front cover of the thermostat. Replace if necessary.

NOTE: Before undertaking any examination of your system, be
sure the power is off to any piece of equipment you are examining.

Thermostats
Some thermostats don’t feature an auto changeover mode that switches between heating and cooling. If your thermostat doesn’t offer this mode, you must manually select the service you want. (On, off, heat, cool, emergency, etc.) Verify that this switch is in the correct mode periodically.

NOTE: Before undertaking any examination of your system, be
sure the power is off to any piece of equipment you are examining.

Breakers
If the system isn’t responding to commands at the thermostat, check to see if the circuit breakers have been thrown. (Typically, there are two breakers per system.) Caution: Circuit breakers carry high voltage power and there is a shock risk. Do not remove the protective panel cover unless accompanied by a trained professional.

NOTE: Before undertaking any examination of your system, be
sure the power is off to any piece of equipment you are examining.

Fuel Levels
During the heating season for customers with Liquid Propane (LP) gas or oil furnaces, periodically check that your tank has fuel. We receive at least two calls every year where the tank is empty upon arrival.

NOTE: Before undertaking any examination of your system, be
sure the power is off to any piece of equipment you are examining.

Outdoor Unit
Keep all four sides and the top of the outdoor unit free of debris. This includes grass clippings. Mow grass with the discharge pointed away from the unit. Also, be careful when weed-eating. A weed-eater can penetrate the refrigeration lines and electrical service, incurring major repairs.

NOTE: Before undertaking any examination of your system, be
sure the power is off to any piece of equipment you are examining.
