After a recent cold snap, several individuals were surprised to see how much more they paid to keep their homes warm.

If you’re looking on tips to keep your next power bill lower, one heating and cooling expert is sharing some steps you can take to make sure the next bill isn’t as big of a shock.

OnTime Service says insulation can play a huge role in keeping your home the right temperature, so check in spots like around doors, windows, and in your attic to make sure there aren’t any weak spots. Having a dirty air filter can cause poor air flow, so experts say make sure you’re regularly changing those out.

If heating and cooling on a budget is a priority for you, experts say keeping up with maintenance will save you in the long run.

“Every year you don’t maintenance your heating and cooling equipment it loses 5% efficiency. So if you’ve gone 4-5 years, its only operating at maybe 75-80% efficiency. That extra 25% would go a long way to making it more affordable,” said Kerry Adkins, owner of OnTime Service.

Another efficiency tip Adkins gives; if your heating and cooling equipment is older than 15 years, it’s time to start planning on getting it replaced.
