It’s the season to schedule fall HVAC system maintenance, but the benefits can last all winter and well beyond. A transitional season like autumn is the perfect time to take stock of the HVAC system status quo. The air conditioner’s running a lot less now and you probably haven’t even fired up the furnace yet. A qualified HVAC technician can inspect all components and assess the level of wear and tear, look for any incipient problems that may trigger a system breakdown this winter, as well as perform vital maintenance procedures to reduce the likelihood of trouble later. If your HVAC system’s still under warranty, this annual checkup is probably required by the manufacturer. But it’s a good idea, no matter how long the air conditioner and furnace have been installed.
The DIY portion of fall HVAC system maintenance is limited to one vital procedure: change the air filter. It’s the single best step to ensure energy efficiency and optimum performance. If you don’t know how, the HVAC tech who performs the maintenance can show you. Change the air filter monthly during the heating and cooling season.
You’re done. Now, here’s what’s involved in a typical fall HVAC system maintenance call by a qualified technician.
At the Furnace
- Clean burners, igniter and combustion chamber.
- Verify proper operation of the pilot light or electronic igniter.
- Inspect heat exchanger for cracks or corrosion.
- Verify that the vent is intact and unobstructed all the way to the roof.
- If the furnace has a condensate drain, check for proper function.
- Test for carbon monoxide when the furnace is running.
At the Air Conditioner
- Clean the indoor evaporator coil and outdoor condenser coil.
- Measure the refrigerant charge. If it’s low, perform leak detection.
- Inspect and test condensate drain system.
- Clean and lubricate moving parts of blower.
- Inspect all electrical connections inside and outdoors.
