One simple way to improve efficiency by 20%

Best way to avoid heating and ac repair.

I know you’ve heard that it’s important to change (or clean) your furnace filter regularly. You may not know why.
Your furnace filter filters the air that circulates through your house. As the filter gets plugged a few things happen.
More allergens make it through the filter, degrading the air quality in your home.
Your blower motor has to work harder, gets hotter, and wears out faster (and it’s never at a convenient time!
The velocity of the air is reduced, which means the hot air cannot be distributed efficiently and your house will feel colder.
Not circulating enough air across your heat exchanger can cause the heat exchanger to operate at higher than designed temperature. In extreme situations, the limit switch will trip, shutting the furnace off. But the mild cases are even worse: the heat exchanger can warp and crack. Once a heat exchanger is cracked, you will need to replace it. It’s usually cheaper to replace the entire furnace.
So do your self and your heating and cooling equipment a favor and set a reminder on your phone or calendar. For more details http://priorityheatingandacrepair.com/blog.html

The best thing you can do.......When you remove the furnace filter, don't stop, remove all that crap, and put a hydronic heating system in.
