Why is your Heater Turning on Instead of the AC?


Why is your Heater Turning on Instead of the AC?As we head into the warmer seasons it's likely time that the ole AC unit starts getting some use. To keep things comfortable in your home you may want to schedule annual AC maintenance to ensure that the system is ready to go for the year, which can help prevent issues such as the heater running instead of the AC system! If this occurs it can be very aggravating, especially on the hottest of days. So why might you be getting warm air instead of the cool breeze that you're craving? Here are three common causes of this unfortunate issue.

Faulty Thermostat

One of the most common reasons that the heater may run when you want the air conditioner running is a failed thermostat. Depending on the type of thermostat that your system uses you may be able to tell if this is the issue based on the other symptoms. If it is battery powered you may want to try changing the batteries. If it has a blank screen (if it has a digital display), the it's possible the system has crashed. It'd be wise to recruit an HVAC professional to identify the root cause of thermostat issues to find out if it can be repaired or if a replacement is necessary.

Bad Thermostat Connection

If the thermostat is hard wired the actual connection could become the problem. If you're able to check that the wiring between the thermostat and the furnace and AC system has not become disconnected. Although another issue that you likely won't be able to spot with a naked eye is a short.

Electrical Problems with Furnace

The furnace could be experiencing electrical problems of its own that is either causing it to run constantly or the blower motor to have failed. In many systems the furnace's blower motor is responsible for distributing the cool air from the AC unit. Problems within the electrical system of the furnace will need to be properly diagnosed by a trained technician and shouldn't be dealt with by a novice as the electrical current could cause bodily harm if not properly handled.
