If you have an older home, it may be time to look at some low-cost home maintenance tips. You don’t have to spend a lot to lower your monthly utility bills. The key could be in your walls. Replacing the insulation will keep air from escaping, helping your house stay warmer in the winter and cooler in the summer.

Fill In the Gaps

With a professional’s help, you can assess your home and what areas need more insulation. In addition to the walls, look in the attic, basement and HVAC system. Make sure you choose insulation that is highly resistant to heat flow. You want a product that will slow down how heat moves from your home to the outside and how it comes into your house from outside. More insulation will prevent your heating system from having to run as often to keep your house comfortable.
