Signs Your Gas Furnace Needs Repair


  • Higher Utility Bills: A sudden spike in your energy bills can indicate a decrease in the annual fuel utilization efficiency of your furnace.
  • Inconsistent Heat: If some rooms in your house are colder than others, it could be a sign of furnace problems.
  • Strange Noises: Any unfamiliar noises coming from your heating system could signal the need for a furnace repair.

Expert Gas Furnace Repair Services

At Mathis-Salfi Mechanical Services, our technicians have extensive experience with various furnace brands and understand the intricacies of different models, be they electric furnaces or gas furnaces.

Our Gas Furnace Repair Process

  1. Initial Diagnosis: Our skilled technicians will first inspect the furnace system, checking components like the pilot light, heat exchanger, and gas valve.
  2. Quotation: After diagnosing the problem, we provide a comprehensive breakdown of the repair work needed and an estimated furnace cost.
  3. Repair: Once approved, our team will embark on the repair service, ensuring all furnace parts, including the air filter and blower belt, are functioning correctly.
  4. Final Testing: We’ll run a series of tests to ensure everything is working properly and your home’s furnace provides consistent heated air.

Why Choose Professional Repair Over DIY?

Tackling furnace repairs without adequate knowledge can lead to further damage and increased repair costs. Not to mention, it poses safety risks. A malfunctioning thermostat, issues with the electrical system, or a faulty heat exchanger can all lead to significant problems if not addressed by a professional HVAC technician.

Preventative HVAC Maintenance

Regular HVAC maintenance  is essential to reduce the need for repairs in your system. This not only ensures your gas furnace operates efficiently but also extends its lifespan. Changing air filters, checking the blower fan, and inspecting the inducer fan motor are essential components of routine maintenance.

What’s the difference between furnace repair and furnace replacement?

Furnace repair addresses specific problems with the furnace. On the other hand, furnace replacement involves removing the old furnace and installing a new one, typically when the current system is old or beyond repair.

Is regular furnace service essential for its longevity?

Absolutely! Regular furnace service ensures that your heating system remains efficient, reduces the chances of unexpected breakdowns, and extends the lifespan of your furnace.

What’s the role of a circuit board in a furnace?

The circuit board controls the sequence of operations in the furnace, ensuring everything from ignition to air distribution works seamlessly.

Can I use my furnace for air conditioning during summer?

A furnace primarily provides heat. However, combined with an air conditioner or heat pump, it can circulate cool air in the warmer months.

How do I know if my flame sensor is malfunctioning?

If your furnace lights up but turns off after a short while or if the pilot light doesn’t stay on, your flame sensor might need cleaning or replacement.

Why is my furnace blowing cool air?

There could be various reasons, including issues with the pilot light, the furnace door not being closed properly, or problems with the electrical system.

What is the role of the high-limit switch in my furnace?

The high-limit switch shuts off the furnace if it gets too hot, ensuring that the furnace doesn’t overheat and potentially cause damage or safety hazards.

Is there a difference between a heat pump and a furnace?

Yes, while both provide heat, a furnace generates heat by burning fuel, whereas a heat pump extracts heat from the outside air and transfers it indoors.

My furnace is over 15 years old. Should I consider a replacement?

Older furnaces might not be as efficient as modern ones. If you notice increased energy bills or if your home’s furnace requires frequent repairs, it might be cost-effective in the long run to replace it.
