Physical Exams Apply To Your Heating And AC, & PMA’s


Like when you see your Doctor for your yearly physical exam, your HVAC manufacturer suggests periodic HVAC check-ups to ensure your system is working properly. When you do preventive maintenance on your unit, you will extend the life of the unit and save you money.

Preventive Maintenance Agreement (PMA) is good for a yearly fee from your local HVAC contractor. A technician will come and test and inspect your HVAC system before any little issues turn into big problems. The technician will check system functions and safety controls; inspect electrical components and connections; ensure proper airflow and change dirty air filters; and inspect pumps, lubricate and check flow rates, where appropriate.


Twice-A-Year Visits
There are different PMA’s available, the technicians usually visit twice a year (once before cooling season and the other before heating season) to make sure everything is working ok. The other option is an all-inclusive lifetime PMA that includes the cost of maintenance, repairs, components, emergency services and equipment replacement.

Remember that warranties are different than PMS’s. A warranty will only last for a certain amount of time, and only apply to specific parts of the unit. If a part is not working and it is still under warranty, the manufacturer will provide a free replacement part. Warranties do not cover labor, so you will still be responsible for the installation costs.


Maintenance Tips
Manufacturers for name brand heat/air units point out that while it is important to have a service technician carefully inspect your unit to uncover any leaks, soot, rust, rotting parts, corroded electrical contacts and frayed wires, there are some simple maintenance tasks you can do to make your unit improve its performance.
They are:

• Keep the intake and exhaust vents clear of debris and ensure there is unobstructed air flow.

• You need to check the thermostat wire entry point and apply caulk so that a draft will not influence the thermostat reading.

• Remove several of the supply and return registers to see if your ducts need to be cl eaned
