Situations Where People Might Run Cooling and Heating Together in Little Elm, TX
To have an AC and furnace running at the same time is not normal. However, some people might consider doing this when they experience certain climatic conditions.
Varying Temperature Days
In northeast Texas, the temperatures can change significantly within a single day. Temperatures in winter and early spring in Little Elm, TX, can be in the 30s in the morning and the 70s or 80s by afternoon. When you experience these temperatures, a thermostat settings conflict is possible.
The furnace and air conditioner might switch back and forth quickly as the temperatures rise or fall, making it appear as if your AC and furnace are running at the same time.
Combating High Humidity
Homeowners in Little Elm, TX, experience a humid subtropical climate. Although winters usually have less humidity, you might have a humid day in winter. This may tempt you to run the air conditioning to reduce humidity in the air while operating the heater because of low temperatures.
However, our technicians’ energy efficiency tips would tell you to utilize a dehumidifier in circumstances like this instead.
Dangers of Operating Heating and Cooling at the Same Time
The primary issue with your AC and furnace running at the same time is putting stress on both systems. When varying temperature days occur, the two systems might start to short-cycle as they deal with quickly rising temperatures outdoors. Short-cycling causes several issues for your HVAC system, including:
- Increased wear and tear
- Reduced energy efficiency
- More frequent repairs
- Less comfortable conditions
We always recommend turning off one system before deciding to start the other system. Turn off the air conditioner on days with mild temperatures until you’re sure you’ll need it.
Malfunctioning Furnace and AC Systems Might Run Simultaneously
Frequently, your cooling and heating systems are operating at the same time because of a system malfunction.
If an HVAC technician recently worked on your system, this person might have crossed the wiring. With incorrect wiring, both systems might kick on together after receiving a signal from the thermostat that the wiring carries to both systems.
You could also have a defective thermostat or system control board, causing both systems to turn on simultaneously.
You should call for repairs as soon as you notice an issue with the heater and air conditioner turning on at the same time. Our technicians can test the systems for malfunctions and fix them.
