Forced air heaters tips

Forced air heaters are a great way of heating your home because they are inexpensive and easy to install. It’s a very versatile heating system. The heater will pull the air from the room, heat it and blow it back into the room.

Here are a few tips for maintenance:

  • Clean or replace the air filters every month. If you have high quality filters, then these may last up to three months.
  • Clean the blower blades and add a few drops of oil to the motor cups.
  • If the motor is equipped with a belt, test the alignment and tensions.
  • Inspect the ducts for leaks and if you find any, seal them using some duct tape.

Sometimes you may find that some rooms are colder than others. Adjust the dampers in the registers.

Use the thermostat and set it once. Let the heating system run for 3 hours to stabilize the temperature and then open the dampers all the way in the rooms that are colder than usual. Adjust the other dumpers as well. Balance the temperature. Wait half an hour before each adjustment.

Fan control:

  • If you feel a chill or a sudden gust of cool air, then you should adjust the control to your fan.


  • Check to see if your furnace has a fan and a limit control. If it does, then DO NOT touch the pointer situated on the limit control side. This will turn off the furnace if it has reached the highest air temperature allowed.
  • keep your hand in front of the warm air register when it starts. You shouldn’t feel a difference in temperature.
  • if you do feel a difference, uncover the control and then turn the fan control a few degrees more or less.
  • to adjust the temperature from the register, then move the on pointer to set the temperature for when you want it to turn on.

Any major repairs or maintenance should be done by a certified HVAC Technician.
