Will Switching Back and Forth HVAC Damage My System?
To begin with, switching your system from air conditioning to furnace will not hinder the overall production of conditioned air. However, switching back and forth can cause the system to shut off. This can happen the air conditioner short circuits; when the circuit breaker trips the outdoor condenser.
This is a common mistake that homeowners experience when switching back and forth from the air conditioner to furnace. If you are running the air conditioner and the system is calling for cooling, the outside unit is on. Now you decide to raise the target temperature it will turn off. A short fuse happens if you immediately turn on the system at a lower setting. This causes the condenser to lock-up. Be aware when you are consistently switching from air conditioning to furnace.
To prevent this from happening many thermostat companies have created a anti-short-cycle feature that use a time delay before switching back and forth. But if it does happen, check the fuses, breakers and outdoor unit for the source of the issue.
Wait at least 5 minutes before starting another cycle. This time delay will give your system time to completely shut off. Modern thermostats have a built-in timer that will start a cycle one another is finished.
