Your forced air system requires air flow to work properly. Duct size and design both contribute to proper air flow and your filter or air cleaner works in conjunction with your system. As the temperatures drop, your furnace will be running much more to maintain a comfortable temperature. The longer it runs, the more air that is travelling through your filter. If you have a one inch disposable filter, you should be changing it every 30 to 60 days.
This past weekend, temperatures were freezing and stayed there for several days. Furnaces all over Northeast Ohio were working double time.
At HAVE, our phones were inundated with service calls. Out of the many calls that we ran, 3 of them were easily preventable. Nothing more than a blocked filter. A furnace starved for air won’t run.
Don’t let this happen to you. Change your filter every 30 to 60 days.
