If you suspect a furnace electrical problem, your first step should be to call in an HVAC repair professional.
With the cold winter nearly upon us, you’ll want to check that your furnace will be able to keep you warm during those freezing nights safely. If you notice that your furnace isn’t working as it’s supposed to, it could be having an electrical system issue, or the HVAC system might be faulty.

Realized my furnace stopped working late last night and forecast called for very cold arctic air blast. Called my regular HVAC company that advertises 24 hour service to find that after 7 PM, there is only an answering service. Same with two more “24 hour service” companies. Then I called Thomas Hoffmann HVAC Company and Nick quickly answered, listened to my issue, gave me a quote and was on his way. Nick arrived soon, completely checked out my furnace, found the problem and did the repair. Because the problem was fairly minor, he even gave me an unexpected and very appreciated discount. Nick was professional, competent, and very engaging. Best emergency, after-hours experience I’ve ever had. Nick saved the day and gave me the peace of mind I needed.
Response from the owner: Thank you, Richard, for sharing your experience; we're glad Nick could provide you with prompt and professional service during such a challenging time. Your kind words mean a lot to us!
Nick was great he was prompt and very patient in explaining the problems with our system and the steps we would take to solve them.I highly recommend using Thomas Hoffman Air Conditioning and Heating!
Response from the owner: Thank you, Benjamin, for your wonderful feedback about Nick's promptness and patience; we appreciate your recommendation of Thomas Hoffman Air Conditioning and Heating!
Furnace would not blow heat on Friday night and after leaving a few messages to several companies, Mr Hoffman called me back quickly and did a service call. Diagnosed the issue and was able to fix the problem. Will need a new unit soon, but nice not be without heat during the holidays! Quote and Invoice receipt done on the spot and detailed! Will use again for sure.
Response from the owner: Thank you, Heath, for your kind words! We're glad Mr. Hoffmann could get your furnace working in time for the holidays and provide a detailed quote and invoice. We appreciate your trust in us and look forward to helping you again in the future!
I was referred via home advisors. And I was so worried about the cost and the distance but Nick came and found my problem and fixed my problem and if I could I would shout-out to the world this is a honest and good company to hire. As a landlord over the road of 5 homes. I can call this company and trust that they will do the job and be honest. And I will not have to pay extra fees or be given a 3 week appointment Just because it's rental property. This is my go to company and I strongly recommend this company.
Response from the owner: Thank you, Annie, for your wonderful feedback! We're so glad to hear that Nick was able to address your concerns and provide you with the honest service you deserve. Your trust means the world to us, and we appreciate your strong recommendation!

Is your furnace acting up? Electrical issues are often the hidden culprit behind heating system failures. While these problems can be frustrating, identifying them is the first step to restoring comfort. Don’t let electrical gremlins leave you in the cold – a qualified HVAC technician can quickly diagnose and resolve these issues, returning your furnace to peak performance. Let’s explore the most common electrical problems that could be affecting your heating system.
8 Electrical Issues That Can Shut Down Your Furnace
Clogged Air Filters: A Silent Threat Your furnace’s air filter does more than just clean your air – it protects vital electrical components. When filters become clogged with dust and debris, your blower motor strains to push air through, potentially overheating and burning out fuses. Beyond efficiency issues, this creates a serious fire hazard. Regular filter maintenance is essential for your safety and system longevity.
Water Damage: The Hidden Destroyer Even minor water leaks can spell disaster for your furnace’s electrical system. When water meets electrical components, it can trigger dangerous short circuits and system failure. Watch for moisture signs around your unit, especially in basement installations or near water heaters.
Loose Wiring: The Shake-and-Break Problem Your furnace’s normal operation creates subtle vibrations that, over time, can loosen crucial electrical connections. These loose wires often create intermittent problems that are challenging to pinpoint without professional diagnostic equipment. Left unchecked, they can lead to dangerous electrical shorts or complete system failure.
Dirty Fuses: More Than Just Dust Fuses are your furnace’s first line of defense against electrical problems. But they can’t properly conduct electricity when they accumulate dirt and grime. This buildup disrupts normal operation and can lead to system shutdowns. Professional cleaning and regular fuse inspections keep your system running smoothly.
Failed Starter Capacitors: The Heart of Your System Think of your starter capacitor as your furnace’s battery – when it fails, your entire system suffers. These components provide the crucial initial power burst needed to start your furnace. While replacement is relatively inexpensive, only trained technicians should handle these high-voltage components.
Transformer Troubles: The Power Conversion Problem Your furnace needs the right voltage to operate safely. The transformer converts your home’s 120V power into the specific voltage your system requires. When transformers fail, your furnace either won’t start or may operate erratically, potentially damaging other components.
Blower Motor Burnout: The Power Surge Risk When blower motors malfunction, they can suddenly draw massive amounts of power, blowing fuses and potentially damaging other electrical components. Regular maintenance can help identify motor issues before they lead to complete failure.
Thermostat Malfunctions: The Control Center Crisis Your thermostat is your furnace’s brain. When it malfunctions, it can force your system to run longer and harder than necessary, leading to electrical overload and potential short circuits. Modern thermostats offer improved reliability and energy-saving features that can prevent these issues.
