4 Most Common HVAC Issues to Prepare for in the Fall Season

As cooler nights creep in, homeowners decide to turn off the air conditioner and turn on the heater. But before you make the transition, it’s best to check whether your heating, ventilation, and air conditioning system (HVAC) are properly working. You don’t want to face a cold house when the temperature drops and your heating system isn’t functioning well.

To ensure that you don’t encounter any problems, it’s best to familiarise yourself with the most common HVAC issues to prepare for come fall.

A Malfunctioning or Broken Thermostat

The problem with your HVAC might not be your furnace but rather your thermostat. You can pull out your owner’s manual to check the operating instructions and review what mistake you might have made. Be sure to push all the right buttons.

Moreover, the change in the season is the perfect time to replace your programmable thermostat’s batteries. These simple maintenance steps can save you the cost of a service call to repair companies.

Dirty Filters

Your HVAC problem may lie with dirty air filters. These filters are your first defence against harmful elements like dust, pollen, and mould, and checking whether they need replacement can save you the trouble. 

Experts recommend having your air filter replaced every one to three months. In the fall, you can begin with a fresh air filter and change it come winter. Doing this also cuts down on the strain on your furnace.

Dirty Evaporator Coil

Your furnace’s evaporator coil’s primary purpose is to heat the air, keeping your home warm on cold winter nights. If you don’t regularly have your air filters replaced, the evaporator coil’s air passages may become clogged or blocked by obstructions. That cuts down on airflow and makes your furnace less efficient. 

It’s best to have your evaporator coils checked if it needs replacement during the fall season so that you can avoid troubles in the winter. You don’t want to encounter a problem with your HVAC system in the middle of a cold night.

Malfunctioning Ignition Sensor

You might be testing your furnace right before the winter kicks in and suddenly hear a clicking noise in your furnace. However, it’s not firing up. There’s a big chance that your problem lies with the pilot light or the ignition sensor that isn’t properly functioning.

Homeowners may feel more comfortable removing the sensor or ignitor and properly cleaning it. Just be sure to turn off the gas to the furnace first before opening the unit. Then, you can unscrew the panel near the front, use a screwdriver to remove the ignitor, and clean it. That should get the furnace to fire up. 

Conclusion

Now that the summer’s over and the seasons are changing, it’s time to prepare your HVAC system and ensure that it is properly working throughout the winter. Be sure to check all parts of your thermostat, including possible loose pieces, a motor that needs to be replaced, and simply dirty insides. Once you guarantee that everything is in working order, you can have a warm and undisturbed fall and winter.
