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.

Annual heating and cooling check-ups and tune-ups are important parts of preventative maintenance. Ernst Heating and Cooling can answer your questions and offer expert advice for the HVAC needs of you and other homeowners in the Metro-East area.
