Your HVAC system relies on a complex network of electrical components to keep your home comfortable. When sudden noises arise or you notice a burning smell, these are obvious signs that there’s an issue with the electrical system. In addition to these, there are other, less obvious signs your HVAC system may need an expert to intervene. Here are the warning signs that indicate you’re experiencing electrical trouble.
Visual Warning Signs of Electrical HVAC System Problems
You might not think flickering lights could come from your HVAC system, but that could be the case. Notice when the lights flicker as you turn your system on; this often indicates a sizing problem, which means your system draws too much voltage at once. It could also be faulty wiring, diverting too much power to your HVAC system. In any case, flickering lights when using your AC or heating unit indicate a deeper issue that needs a professional to diagnose.
If your circuits trip after an HVAC system cycle, it’s a clear sign of an electrical problem. You shouldn’t repeatedly flip them back on just to fix the issue one more time. Faulty electrical wiring at any part of your HVAC system is a serious issue best treated by a pro.
Obvious Signs: Burning Smell and Humming
That telltale electrical whirr when your HVAC system runs isn’t a coincidence; the humming sound often comes from overworked electrical parts, and they could eventually spark or shut down from a malfunction.
A burning smell is the most concerning red flag for good reason, as it means some part of your system is being overheated. The risk of electrical fire is higher in this case, and you should shut off your HVAC system immediately and call a professional.
Thermostat Signs
Your thermostat may be a hidden clue to your HVAC system’s electrical issues. If it reads inconsistently, fails to adjust temperatures, or doesn’t respond at all, there’s likely an issue with the control board or wiring. Luckily, this is one of the easiest HVAC repairs for trained experts, and they can likely get your thermostat and HVAC system communicating like they should in no time.
When to Call a Professional
HVAC repairs are always better left to experts. If you notice burning, humming or buzzing, see sparks or experience power outages of any kind while running your HVAC system, get in touch with a pro right away. It’s not worth the risk of electrical fire or total system failure to prolong problems.
If you notice any of these warning signs, don’t wait to get help because the problem will only get worse and put you and your family in danger. If you need HVAC maintenance or other services in Newnan, GA, look no further than the skilled team at E Dennis AC Inc.!
