If you are new to the world of indoor cooling, you may wonder why your air conditioner is running when the heat is on. Even the best air conditioners, after all, run into maintenance issues, and they could cause this specific problem. So, what to do when the AC runs during the winter months and how to fix it? Keep reading to find out.
If your air conditioner keeps running while turned off, particularly when the heat is on, there are many reasons as to the cause. If the air conditioner heater is not working, that could have caused some integration issues. If you recently replaced the heat pump with an air conditioner, that could cause some issues. Another reason why this happens? When your air conditioner thermostat is not working, the system doesn’t know what to do.
Regular maintenance will ensure your AC unit is in top working order and allow you to catch any developing issues early.
No matter the issue, even if your air conditioner makes a loud noise when shutting down, here are some essential troubleshooting tips to solve the problem.
This is an obvious one but easy to miss. If you have a hybrid HVAC system that handles both heating and cooling, or even if you have an unaffiliated system, there could be some miscommunication when it comes to thermostat settings. Give that thermostat a check to ensure it is not set to, say, 65 degrees Fahrenheit. Set it to the appropriate temperature to suit your taste and give it an hour or so and see if the problem has resolved itself.
If your air conditioner is a hybrid model outfitted with a heat pump, it is helpful to understand how this system works. The heat pump here uses the same ductwork and components as the AS unit, just in reverse. So head to your heat pump settings and disengage the air conditioning unit. You may have to reset the whole system for the changes to take. Are you not sure if you even have a heat pump? Check the manual that accompanied your HVAC system.
Dirty air filters can impede the efficacy of both your air conditioner and heater.
Call a competent professional to handle the situation when all else fails. These pros are well-trained to suss out any conflicts between your air conditioner and your heater.
STAT: If your fan is switched to the “on” position, it will continuously run. You should set it to the auto position, so it only runs when the HVAC unit is running. (source)
