Have you ever woken up in the middle of a winter night, shivering under the blankets and able to see your breath? Or have you ever watched the thermostat creep into the upper 80s during a record-setting heat wave, realizing you haven’t heard the air conditioner kick on? If so, your heating or cooling system was on the fritz—and (of course), it happened at the worst possible time.
These systems not only fail when you need them the most, but also during the hardest time of the year to get a heating, ventilation and air-conditioning (HVAC) contractor to come by for repairs. Naturally, technicians are at their busiest when these systems are busiest. So, unless you have a relative in the business, the best way to ensure your heating and cooling systems keep working is to maintain them properly.
