Programmable Thermostat

You should change the filter in your furnace every three months, so if you started using your heater in October, it’s definitely time to make the swap! But did you know you should also check your filter every month during the heating season to see if it’s dirty? A dirty filter will slow down air flow and make the system work harder to keep you warm— wasting energy. Always using a clean filter can reduce your heating costs by up to 15%. If in the average month you spend $100 to heat your home, this simple swap you could save you over $90 each year.

And, as an added bonus, always using a clean filter will prevent dust and dirt from building up in the heating system — minimizing your risk of expensive maintenance and early system failure.
