As the world turns, the requirements for seasonal HVAC care rotate too. Systems involved in heating and cooling your home impose very different maintenance procedures based on the specific time of year. Scheduling annual preventive maintenance by a qualified HVAC contractor for both heating and cooling seasons ensures that the correct components get the necessary inspection, manufacturer-recommended service, and testing required for optimum reliability, efficiency, and performance.
Here’s a rundown of typical items of seasonal HVAC care according to the time of year:
Cold-Weather Heating Maintenance
- Inspection and cleaning of the furnace burner and cleaning and testing the igniter.
- Inspection of the heat exchanger for cracks or other defects that could leak dangerous fumes into the system airflow.
- Check the integrity of the furnace vent pipe all the way to the roof. Make sure the vent cap and screen are intact and that no debris, such as a bird’s nest, is present in the pipe.
- Check blower drive belt for wear and proper tension.
- Install a new air filter.
- Start up the furnace and verify proper operation at the thermostat.
- Check warm airflow volume at all supply vents.
- Sample combustion gases to make sure proportion of hazardous fumes, including carbon monoxide, meets safety specs.
- Test carbon monoxide detectors in the house for proper operation.
Warm-Weather Air Conditioner Maintenance
- Clean the evaporator coil in the indoor air handler. Inspect and test the condensate drain function.
- Measure the refrigerant charge. A low reading indicates a leak that must be located and repaired.
- Check blower drive belt for wear and proper tension.
- Verify that supply and return vents are fully open and not blocked by any objects.
- At the outdoor unit, access the condenser coil and clean it. Look for evidence of animal intrusion inside the unit such as nests, chewed wiring, etc.
- Clear away growth of vegetation to create two feet of open space on all sides.
- Start the unit at the thermostat and check for cool airflow volume at all supply vents.
