Having a dirty air filter can cause your ac not to run properly. When it is clogged it restricts air flow and it causes the AC to work harder making your bill higher and potentially harming your system. You should make sure you check and change the filter every month. Filters are available through us on our website and we can come and change them for you. If after you changed the filter, the AC still isn’t running like it should then we can figure out the issue and fix it for you. Call Bartlett Heating and Air today to figure out which filter is best for you.
