Just as doctors encourage yearly physical exams, many heating, ventilation and air-conditioning (HVAC) manufacturers suggest periodic HVAC checkups to ensure your system is running properly. Preventive maintenance will extend the life of your unit and save you money.
With a Preventive Maintenance Agreement (PMA), offered for a yearly fee from your local HVAC contractor, a technician will come to your home to test and inspect your HVAC system before any minor issues turn into major problems. Among other things, 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.
Although different PMAs are available, technicians usually visit a home twice a year (once before the cooling season and once before the heating season) to ensure everything is working properly. Another all-inclusive option is a lifetime PMA that includes the cost of all maintenance, repairs, components, emergency service and equipment replacement.
