Be Familiar with the Steps in a Normal HVAC Tune Up

An HVAC tune up can save money both now and later. This service is a detailed inspection of cooling and heating components by a certified technician and includes a manufacturer-recommended list of maintenance procedures. It keeps HVAC components operating at optimum efficiency while maximizing cooling or heating performance and extending system life span. Moreover, these inspection and maintenance procedures reduce the potential of a minor malfunction morphing into a major event that could require substantial repairs and expense.

Signs that you may be overdue for an HVAC tune up of your AC or furnace include:

• An unexplained rise in electric or gas bills.
• AC air isn’t cool enough. Furnace output isn’t sufficiently warm.
• Airflow from vents is insufficient.
• Excess condensation on AC components.
• AC or furnace cycles on and off rapidly.
• Increasing indoor humidity.
• Unexplained noises from the air conditioner or furnace.
• Indoor temperature does not match thermostat setting.

Here are some of the specific procedures a qualified technician may perform during a maintenance tune up:

• Change the system air filter.
• Inspect the AC condensate drip pan and drain system.
• Inspect the function of the central AC contactor.
• Test the level of air-conditioning refrigerant.
• Clean air conditioner evaporator and condenser coils.
• Inspect the gas furnace heat exchanger for cracks.
• Check the furnace airflow for the presence of carbon monoxide.
• Make sure all supply and return vents are open and unobstructed.
• Verify accuracy of thermostat calibration and review seasonal thermostat settings.
• Inspect system blower motor and drive belt.
• Visually inspect HVAC ductwork for leakage, disconnected segments, or other deterioration.
