Fall HVAC Check

Well everybody, fall is here. The leaves are turning, the air is dryer, and the NC State Fair is almost over. Where does time go? It is also that time of the year where we start thinking about turning our heat on for those cool nights, and that means that we need to think about having our heating system checked by a licensed heating and air contractor. In this edition, we will go over several suggestions to prepare you for the upcoming cold weather.

First, for the gas heating systems, I would especially recommend this evaluation. The most important reason would be to insure that there are no cracks in the heat exchanger. Cracks in the heat exchanger lead to carbon monoxide (CO) entering into the home through your HVAC system. (If you have any gas appliances in your home, install a CO detector.)

Second, for heat pump systems, you want to make sure the heat pump has the proper amount of refrigerant in the system so the unit will heat adequately. You want to avoid the auxiliary heat strips from coming on whenever possible. When the auxiliary heat strips activate, the amount of electricity greatly increases. When the thermostat is raised 3+ degrees, the auxiliary strips turn on to supplement the system until the desired temperature is reached. It is recommend that when the thermostat is in the heat setting, a comfortable temperature be found and then set and left at that temperature. This will be the best way to save your electric heating cost.

Third, an evaluation will ensure that your system is operating properly and as efficient as it can. If a problem is found during the evaluation of your system, it is usually cheaper to repair now than in a month or so when the busy repair season hits, not to mention the wait time.
Lastly, remember to change your filters as needed to keep the system clean and operating properly. On the note of cleanliness, the first time the heating system is turned on after a long spring and summer, there may be a burning odor. This is the smell of dust and other particulates burning off of the heat chambers or auxiliary heat strips. But, if you feel that the odor is not normal or you see smoke, turn the heat off and call a licensed heating and air contractor or the fire department (911).

Well, this should get you started in the right direction.
