In this latest video, our team at #Toshack explains the why and how often you should change your home furnace filter. With over 80 years of experience performing #FurnaceRepair in Kingston and Brockville, we hope these tips will help improve your life. br One question we are often asked is when and why to change the filter in your furnace. Small or entry-level 1" furnace filters ought to be changed once every three months at a minimum. For larger 5" furnace filters, you should change the filter annually, unless you keep furry pets like cats and dogs, whose hair can clog the filter more quickly. br Why do we change our air filters? Easy – because they’re dirty! Dirt trapped in your filter won’t be trapped in your lungs, and dirty filters restrict the air flow through your furnace, meaning that it takes more energy to heat or cool your home, which will add costs to your energy bills. br We provide HVAC, heating, cooling, air conditioning or plumbing in #Brockville, Cornwall, Smiths Falls and #Kingston.
