The longer and harder a furnace has to work, the more wear and tear it sustains, and the more likely it is that the furnace will need repairs. Often the steps you take to improve the lifespan of your furnace will also help to decrease your heating costs.
Those who take care of their furnace installation will find that their furnace takes care of them:
Replacing Your Filter with Fidelity
A filter is designed to stop particulates in the air in your home before those particulates get your furnace and/or your ducts dirty. Unfortunately, the more particulates that build up on your filter, the less efficient it is. A filter that is clogged with particulates will choke off the air supply flowing into your furnace.
While you might think that you are cutting costs by trying to get as much life as you can from your filter, you often end up paying more in heating costs even as you put more strain on your furnace.
Don't Duck Your Duties to Your Ducts
Ducts develop leaks over time. The pressure of air pressing on the walls of the ducts causes joints and seams to weaken. The bigger the leaks in your ducts are, the smaller the volume of air that actually reaches your home. In the typical home, about 30% of the heated air generated by your furnace is lost due to duct leaks.
Thus, if you want to maintain the efficiency of your furnace to keep your heating bills down even as you decrease the wear and tear on your furnace, you need to check for leaks in your ducts and fix them when necessary.
Weather-Proofing Your Windows
Windows do not provide much insulation for a home. Even a double-pane window will allow energy transfer. If you want to decrease the transfer of heat out of your home, you should consider installing a protective window film. Window films will reflect heat back into your home while they reflect cold outside air back into the atmosphere.
The more steps you take to protect your home from heat loss, the more efficiently your furnace runs. The less your furnace has to run, the less you have to pay to keep your home warm. By the same token, a furnace that runs less frequently is a furnace that breaks down less frequently. A smart homeowner will take all the steps possible to improve the efficiency of an HVAC system.
