⚠️URGENT!!! ⚠️
🦸‍♂️ Hey Friends ✋️ 🫸 Please do us both a favor...📵 Stop scrolling for a minute📵 and go check your furnace filter. ✔️👍🦸‍♂️
Out of sight=out of mind. 🤔 It is easy to forget to check your furnaces air filter every month. As you can see in the picture a dirty filter or dust build up in the cups of the blower wheel can cause your furnace to overheat and short cycle on the high limit switch. This damages and shortens the lifespan of the furnace not to mention the loss in capacity and efficiency. The Furnace runs twice as much using twice the gas and electricity needed to heat your home.

The inefficiency with your AC system might not be visible to the naked eye.. but at its core air flow is restricted and presents a major problem. Call the Furnace Guy and get your A/C unit running back to 100% capacity.

Thank you
