The hot temperatures underscore the importance of keeping the air conditioning (A/C) running. During this time of year, air conditioning repair companies are slammed, working to fix malfunctioning heating, ventilation, and air conditioning (HVAC) systems.

To ensure your A/C stays functioning during the hottest of days, there are steps homeowners can take.

According to local HVAC professionals, you should have your HVAC unit inspected twice a year: once for summer and once for winter.

They also recommend checking your system’s filter at least once a month. Depending on which kind of filter you have, they can last anywhere from four months to a year before it needs to be changed.

If the same problems persist, or the costs of repairs begin to get too pricey, it may be time to consider investing in a new one.

With normal wear and tear, HVAC systems can last between 10 to 15 years. But with good maintenance, they say it can last more than 30 years.
