Preventative HVAC Maintenance

An air conditioner's components require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases. Both our annual and bi-annual maintenance packages offer the same 20+ point service; however, we encourage our customers to consider the bi-annual package ordinarily completed during the spring and fall. This allows one of our technicians to evaluate your system in both states of heating and cooling.

A list of the tasks performed during routine HVAC maintenance are listed below.
