A Precision Tune-Up Can Keep Your System From Quitting On You When You Really Need It

Posted On: June 06, 2011

Preventative maintenance of your home’s heating and cooling systems is very important. Annual or semi-annual maintenance can help prolong the life of your equipment and help you avoid costly repairs in the summer and winter months. A precision tune-up is one the best ways to keep your heating or cooling system from quitting on you when you really need it.

The best time to plan for a tune-up is right before the peak seasons of summer and winter. In spring, check your air conditioning unit and schedule a precision tune-up with a certified technician. In the fall, do the same for your heating system before winter hits.

Be sure to perform a home check-up of your heating or air conditioning systems before scheduling a tune-up. Performing a home check-up can help you identify what parts of your home’s heating and cooling systems need to be further examined by a trained technician and then possibly repaired.

Here is a list of things you can do on your own:

  • Check that the thermostat performs properly when you are at home and away.
  • Listen for squeaky parts or odd sounds. Note where the sounds are coming from within your systems and inform the technician.
  • Check for leaking water when the air conditioning system is in use.
  • Check, change or clean the air filter.

Here is what you can expect a trained technician to do when performing a precision tune-up:

  • Ensure all moving parts and motors are lubricated. Poorly lubricated parts can cause your system to work harder than necessary, increasing energy use and costs.
  • Check the air conditioning drainage system. Ensure all water properly drains from the system when in cooling mode.
  • Clean air conditioning coils and check refrigerant levels.
  • Adjust blower components for optimal air flow and efficiency.
  • Check gas connections, pressure, burner combustion and heat exchanger.
