Preventive Maintenance Agreement (PMA) Program

It's vital that you have your heating and air-conditioning equipment serviced and cleaned at least twice a year. Without these regular check-ups and cleanings, your equipment can become less efficient over time and it's lifespan is greatly reduced. As with any machine, proper maintenance is smart and wise. That's why we created our PMA program.


Twin Air understands your heating & air-conditioning system and can eliminate money-wasting problems. We have developed a customized program that addresses the problems we see most often. The comprehensive Service and Maintenance Agreement we offer is designed to:

• Reduce the possibility of a heating and air-conditioning breakdown.
• Reduce your utility and repair costs.
• Maintain or enhance your current level of comfort.
• Provide you with discounted labor costs.

It is important to note that prior to signing up for this contract we require that you purchase an initial cleaning of your equipment. This allows us to do a needed assessment of the units, as well as preventing any needless maintenance of equipment that should be replaced.

The Outstanding Benefits

• Some heating and air conditioning problems can double operating costs without reducing comfort; in other words: the affects of the problem may only show up in your wallet.
• Up to 80% of all a/c and heat pump compressor failures could be eliminated if the problems were corrected in a timely manner.
• "Freon" (refrigerant) should never need to be replaced. If it must be added every year, there is an expensive leak that must be repaired (according to the EPA).
• A dirty evaporator, condenser, and blower could increase a/c and heat pump electrical usage by 50% or more.
• It only takes 100th of an inch of dirt or film on an evaporator to reduce it's efficiency by 5%.
• Un-repaired small problems lead to very expensive repairs.
• Depending on the current condition of your equipment, this service may pay for itself several times in energy savings alone.
• Safety checks can eliminate dangerous problems.
