Wondering why you had a sudden spike in your electricity bill? Or maybe you’d been running your AC for extended periods of time, but it’s no longer cooling your house the way it did before?

If so, we hate to be the bearer of bad news, but your air conditioning unit just might be malfunctioning. And it’s likely your system’s heater is turning on even when it’s on cooling mode. But what would be causing your heater to suddenly activate? Get informed about the most common reasons below:


A Faulty Thermostat     


Examine your system’s thermostat. Is it still working well? If it doesn’t seem to be working, then most probably it’s the reason you’re having a problem. But in this case, you might need to get professional help from an HVAC technician.


On the other hand, if your thermostat is battery powered, you might want to try changing the battery, as this could very well be the problem. Are you seeing a blank screen? Could be as simple as the breaker being tripped, so you may want to go check on that as well. If none of your breakers seemed to be the issue, then your thermostat might be defective and you need to have it looked at and/or replaced.


Faulty Thermostat Connection


Another issue that might be causing you trouble is that the thermostat connection to the furnace and AC unit might have been disconnected. For all you know, the wiring from the thermostat to the units could have been damaged or you might have set your thermostat into cool mode, but the furnace and the AC unit aren’t setup to trigger properly.


Check for water damage or damage caused by rodents, also, as it may have been the cause of a short in the circuit. Again, only a certified HVAC technician can help you fix this issue, so if you find yourself in need of fast and affordable HVAC service, One Hour Air in Covington LA has your back.


Electrical Problems With Your Furnace


Your AC and heater work closely together. If you haven’t researched this yet, the blower within your furnace is responsible for circulating cold air throughout your home during summer.


Inside the furnace is a complex network of wires and circuit boards which, over time due to water damage, can malfunction and short out. And that’s one of the most common causes of issues with your heater. The furnace’s motherboard is supposed to tell it exactly what to do and when it isn’t working properly, the cooling signals the furnace receives from the AC unit and thermostat will not be properly understood, which is what is causing the heater to turn on.


We know how frustrating dealing with a malfunctioning HVAC system is. But the good news is that most of these problems are relatively easy to fix without a “through the roof” kinda cost that we all dread.
