When it comes to whole house heating and air conditioning, the “Central” or “Zone” system is one of the most economical and efficient options. But as these systems become more technologically advanced, or as older systems age, certain problems can develop. Below we’ve highlighted three common HVAC zone problems:

1. A malfunctioning thermostat: The most prevalent problem that occurs with zone systems is a malfunctioning thermostat. The good news is that it’s often just a simple fix that will get things back in working order. Many issues can be resolved by simply changing the batteries or doing a reset of the thermostat. Sometimes a replacement may be necessary and most handy homeowners can tackle this project by themselves.
2. Your dampers are stuck: Dampers help control airflow in your home, and accumulated dust or worn parts can sometimes make your dampers “stick” in a closed, open or half open position. Cleaning dampers can be difficult because of their location inside the ductwork, so a phone call to a reliable and trusted HVAC company may be in order.
3. A bad control panel: Considered the “brain” of an HVAC system, the control panel monitors and adjusts many of your system’s functions. When they fail, you can experience numerous problems — from the system not responding to your thermostat’s commands to a complete malfunction. If you suspect you have a control panel issue, contact a professional.

Remember, in order to keep your zone system running well and avoid unnecessary failures, always change your filters on a regular schedule and consider investing in a high quality maintenance program from a reputable HVAC company.
