Your home HVAC system keeps you cool during the summer and warm during the winter. To ensure that your furnace is working in tiptop shape when you need it the most, you have to clean your system routinely and replace its filters.
Before you do anything to your heating and air conditioning unit, make sure you shut off the power to your unit, which either involves a shutdown switch or a breaker, and that you also cut off the gas supply, if applicable. Once it’s safe to do so, remove the front panel from your furnace to expose its working parts and assess its condition.
