Regular maintenance for your HVAC system is a must if you want to avoid unnecessary repair calls, higher bills, and shortened equipment life. If you use a heat pump for your home, you probably already know how vital it is to arrange maintenance from a professional during the spring so that the system is ready to handle the heavy heat during a Florida summer. (If you didn’t know that before, now you do.) But you may not realize that the heat pump must have two maintenance visits each year, with the second coming during fall.
