As the temperature begins to drop and days begin to shorten, many homeowners are switching their systems over from air conditioning to heating. It is important to ensure that the system will be ready for that seasonal switch over. Here is a winter HVAC maintenance checklist for homeowners to use to ensure the heat will be working properly when the temperature begins to drop.
Try to renew filters on a monthly basis. Dirty filters reduce air quality inside the home, increase energy bills, and have the potential to damage HVAC equipment. With unclean filters, furnaces have to work harder to circulate air throughout the home, which may lead to breakdowns sooner than expected.
Be sure to inspect not only wall units, but the thermostats on your furnace as well. Check and calibrate using a mercury thermometer if necessary, and verify proper on/off signaling of the furnace. Thermostats should be set between 68 and 72 degrees for maximum energy efficiency and comfort.
Check and Tighten Electrical Connections
Measure the amperage draw of the blower fan motor and lubricate the motor and fan pulley if needed. Loose or faulty electrical connections can cause unsafe conditions when your system is operating, and can potentially reduce its life span.
Check All Gas or Oil Connections
Gas pressure, burner combustion, and the heat exchanger need to be inspected. If these connections are not tight, a fire hazard can develop. A dirty burner or cracked heat exchanger will cause improper burner operation. Either of these conditions can cause your equipment to operate in an unsafe and inefficient manner.
Lubricate All Moving Parts
Burners should also be cleaned, and the heat exchanger should be inspected for cracks. If there is insufficient lubrication, it can cause friction, which will increase the amount of electricity used.
Check For Proper Burner Ignition
If your system uses a standing pilot light, verify that it is working properly. Vents, supply, and return grilles should be inspected for obstructions, and carbon monoxide levels should be checked.
Prepare Your A/C Unit For The Winter
Ensure that there is no standing water in the condensation drain pan. Pooled water can cause damage in the house and can affect indoor humidity levels. Indoor evaporator and outdoor condenser coils should be cleaned, and the refrigerant level should be checked. If you have an outdoor unit, protect it with a properly-fitted AC cover to protect against the harsh winter elements.
