A Comprehensive Winter HVAC Maintenance Checklist

Fall is in full swing across the country, and leaves are beginning to change. In hot, humid, and sunny Florida, it’s still almost 80 degrees each day. Although downright cold days are few and far between, cold nights can and sometimes do occur. That’s why your winter HVAC maintenance checklist is so very important and you should complete it before fall ends.

DIY Winter HVAC Maintenance Checklist Items

  • Check Your Air Filter – This is one of the items on your winter HVAC maintenance checklist you can handle on your own. Your air filter should be changed every three months at a minimum, but more often if recommended by the manufacturer or if you notice it is visibly dirty. A clean, free-flowing filter is vital to your HVAC system’s performance, and this is true whether you’re using your air conditioner on an 85-degree day or your furnace when it drops to 42 degrees at night.
  • Determine the Accuracy of Your Thermostat – Next, another step of the winter HVAC maintenance checklist you can check off is determining the accuracy of your thermostat. To do it, just make sure all the buttons and settings work as they should, then set your thermostat to a comfortable level. Place a room thermometer (the more accurate, the better) very near to the thermostat, then wait about an hour. Make sure the two readings are within two degrees of one another, but be sure you give those two degrees as leeway.

Lubricate Moving Parts and Motors

Your HVAC service technician will handle this part of the winter HVAC maintenance checklist for you. Both your air conditioner and your furnace rely on several moving parts – namely the blower motor – to move cooled or heated air throughout your home. These parts get a lot of use, so it’s vital to keep them in good working order. Your HVAC tech will check their operation and then lubricate them according to manufacturer specifications.

Check Power Supplies and Fuel Connections

Your technician will also check to ensure that your power supplies are operating correctly and that all your fuel connections – whether gas or oil – are safe and proper. This will keep you and your family safe throughout the cold nights, and it will allow you to sleep easier.

Determine Coolant Levels and Gas Pressure

Even in the dead of winter, there may be days when you need to run the air conditioner to reduce the humidity in your home. During your winter maintenance call, your HVAC technician will check not only the gas pressure going to your unit (if it is a gas-fired furnace), but he or she will also check your refrigerant levels. Too little or too much refrigerant can impact the efficiency of your system as well as your overall comfort.

Check Flue Safety and Damper Positions

Finally, HVAC techs might also check the proper operation of your furnace flue, which allows for combustion gases to escape. If your flue is not operating properly, carbon monoxide and other gases can build up, making you and your family sick – or worse. Dampers are also vital to your comfort as these help direct airflow through the flue and through your duct system.

The winter HVAC maintenance checklist includes other items that your HVAC technician will do on-site, but these represent the most important. It’s all about your comfort, your safety, and the efficiency of your system, so be sure to schedule your winter maintenance today.
