HVAC Preventive Maintenance


HVAC Maintenance Agreements = Savings

Why is Preventative Maintenance so Important?

HVAC preventative maintenance agreements (PMAs) are agreements between you and your quality contractor for scheduled inspections and maintenance of your heating, ventilation, and air conditioning system. Sometimes PMAs are also referred to as “planned maintenance agreements,” “start and checks,” or “preventative service agreements.” At Air Concept Solutions, we offer our “Maintenance Agreement Plan (MAP)” to help ensure your system is working correctly and efficiently when you need it. This includes scheduling semi-annual check-ups to maintain peak efficiency, prevent utility overpayment, and avert system failures through predictive maintenance that can help extend the life of your HVAC system. Our maintenance agreement plan visits usually take place in the fall and spring sessions when a service technician will 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. It is a very inexpensive way to make sure your systems are working reliably and to avoid excessive utility bills.

Out of Sight, Not Out of Mind?

The old but true cliche “out of sight, out of mind” is often the reason for neglected maintenance guidelines for your HVAC system. HVAC systems are usually installed where they aren’t seen, such as in a section of the basement, a closet, on rooftops, or in mechanical rooms, making them easy to be neglected. The systems are simply taken for granted, until they fail. Decreased efficiency, utility overpayment, discomfort, loss of productivity, eventual premature replacement, and higher repair costs are the result.

Just because your HVAC system is out of sight, does not mean it should be neglected. Getting your HVAC system checked twice annually is just as important as changing the oil in your car every 3,000 miles.

What should I expect my technician to do during a MAP visit?

(Some of the basics) checking system functions, safety controls, and adjust the operating sequence where appropriate.

Have cleaning and inspection every 6 months on your HVAC equipment to ensure proper performance and savings.

  • Check blower motor amps
  • Check heat strip amps
  • Check condition of drive belt(s)
  • Check for loose or corroded connections
  • Inspect for visible signs of oil which may indicate refrigerant leak
  • Test capacitor microfarad
  • Inspect condition of relay/contactors
  • Wipe down AHU cabinet
  • Clean auxiliary drain pan
  • Check temp drop across evaporator
  • Clean out primary drain line
  • Place algaecide tablets in primary pan
  • Inspect drain line for proper grade and support
  • Inspect condition of evaporator coil
  • Check that float switch breaks “red” – safety feature

Heat Pump / AC Condenser

  • Check high and low voltages
  • Check compressor amp
  • Inspect for visible signs of oil which may indicate a refrigerant leak
  • Check refrigerant charge
  • Clean condenser coil (does not include deep chemical cleaning)
  • Test capacitor microfarad
  • Inspect condition of relay/contactors
  • Check for loose or corroded connections
  • Wipe down unit cabinet
  • Clean interior of unit & removal of leaves
  • Check operation of defrost board (heat pump)


  • Check condition and operation of thermostat

  • Check for loose or corroded connections
  • Inspect gas piping
  • Inspect flue vent
  • Wipe down furnace cabinet
  • Check temp drop across burner

Above are just some of the basics of what a technician should check on your HVAC system. Depending on what type of system, there may be other required items that need to be checked. Extra costs may apply for deep cleanings on your HVAC systems. Some companies state they have a 15 to 18 point check list, but this may be a play on words to repeat there items in different meanings or terms, to make you feel you’re getting the best bang for your buck. A standard time to complete a basic PMA is 1 hour minimum per system. Some MAP visits may even be up to 2 hours or more hours depending on the degree of cleaning and the type of maintenance work needed. This is also a time for you to ask questions about your system and bring up other issues that might need to be checked.

We are not a typical HVAC company and we hold all our technicians accountable to:

Do the Right Thing ” for you the customer.

What is the bottom line for me?

Savings: PMAs typically more than pay for themselves through higher efficiency, less utility overpayment, and contractor discounts. PMA customers typically receive a discount on all parts and services performed during the entire year.

Peace of Mind: Predictive maintenance will mean fewer system failures and longer life for your HVAC equipment.

Priority Service: Should a system failure occur during the heat of the summer or the cold of the winter, customers with PMAs generally receive priority service.

Continuity: Many contractors are often able to assign technicians to the specific customers. That way, you get to see and know the same service technician, and he or she becomes more familiar with you and your equipment.

Why Routine Service?

1. Maintains High Efficiency.
2. Lengthens Equipment Life.
3. Avoids costly Breakdowns.
4. Peace of Mind
