Annual maintenance for central air and heating systems can save you up to 10% on your energy bills and prevent breakdowns. Some people think they don’t need to tune up their heating system because they don’t use it that much. This is not true! Not only is your heating system “on” more than you realize, but it also works together with your central air system to cool your home. Also, tuning up your heating system allows us to check for dangerous carbon monoxide leaks.
