A1: Preventive maintenance = $avings! Preventative Maintenance Agreements (PMAs) are agreements between you and your Air Control Central quality contractor for scheduled inspections and maintenance of your heating, ventilation, air conditioning (HVAC) and/or refrigeration system(s). PMAs are generally scheduled semi-annually to maintain peak efficiency, prevent utility overpayment, and avert system failures through predictive maintenance that can help extend the life of your HVAC system. All of which add up to cost savings for you.

PMAs usually consist of Fall and Spring scheduled sessions for an Air Control Central service technician to go through your entire HVAC system preparing it for the upcoming season in a proactive approach before system failure and prior to overpaying your utility company.

The inspection may include, the inspection of your business or home's ductwork, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filter, driers, registers, grills, drain pans and evaporator coil.

A4: Maintenance and service play a key role in the lifecycle of a heating or air conditioning system. If all recommended maintenance and service actions are taken, an air conditioner can last 12 to 15 years and a gas furnace 15 to 20 years.

A5: There are many different types of HVAC equipment. A typical preventative maintenance visit will include a complete systems function and safety inspection, including filter and belt service.

For Air Conditioning systems:

• Indoor and outdoor coils are cleaned as required
• Condensate drain lines are inspected for restrictions
• Refrigerant levels are checked, and appropriate action taken if any leaks are discovered

For Heating systems, which can develop cracks in the heat-exchanger and sooting in the combustion system - inspection and cleaning is performed. Also air/fuel mixtures are adjusted to maximize combustion efficiencies and prevent the formation of deadly carbon monoxide.

A9: It is generally a good idea to replace the indoor coil if you are also replacing your air conditioner.
