10 Signs That Your Gas Furnace Needs Repairs

By Aztil –

As we enter the holiday season, it’s time to fire up the heater and stay cozy on those cool winter nights. Even Florida has a winter, though we may prefer to crank up the heat until shorts are still comfy indoors. To do that, your gas furnace becomes the most important appliance in the house. After that initial smell of burning dust, your furnace should hum along all winter. But what if it doesn’t? We don’t use our heaters for much of the year, but reliable heating in the winter is vitally important. Knowing when to call for furnace repairs can keep you cozy all season and provide peace of mind for next winter. Aztil Air is here to help. Let’s look at the ten signs that your gas furnace needs repairs.

1. Strange Noises

Furnaces rarely make noise. You may hear some creaking right at first, but any serious noises are a bad sign.

  • Baning
  • Clanging
  • Squealing
  • Scraping

These sounds mean there is something wrong inside your gas furnace. These sounds can indicate loose or faulty components. Calling for repairs ASAP is the best way to stay safe and warm.

2. Inconsistent or Insufficient Heat

Your gas furnace should provide a steady flow of heat throughout the house. If you’re not getting enough heat, if the heat comes and goes, or if certain parts of your house have cold spots, there’s a problem. It could be an uncalibrated thermostat, clogged filters, problems with the blower fan, or a problem with the core heating system.

3. Short Cycling

A short cycle is when your furnace turns on and off repeatedly. This means it is not completing a full heating cycle and is likely taking damage and wasting energy with a very short cycle. Short cycles can be caused by a clogged air filter or signal problems from the thermostat. It can also happen if the furnace is overheating for some reason.

Quickly call Aztil Air for repairs if a gas furnace short cycles, as it could be dangerous and inefficient.

4. Rising Energy Bills

Did your energy bills suddenly spike when you turned on the heater? Does it cost way more to heat your home this winter than last winter, even in Florida’s mild cold season? If so, then you may have a furnace problem. Your furnace is working harder than it should. It could be an issue with your filter, ducts, or worn-out components that must be replaced.

Get your furnace inspected and tuned up before it costs a fortune in electricity or gas.

5. Yellow or Flickering Pilot Light

A pilot light provides a gas furnace with an essential function: lighting the gas used for heating. A healthy furnace should have a steady blue flame in the pilot light. If the flame goes yellow (a cooler flame) or flickers, it could indicate a problem with the furnace’s ventilation or gas supply. It could even be a sign of carbon monoxide leaking.

Immediately turn off your furnace and call Aztil Air for emergency repairs.

6. Unpleasant Smells

The burning dust smell when you first turn on your heater for the season is normal. But unusual smells after that should be a red flag.

  • A rotten egg smell can indicate a gas leak. Immediately shut off your furnace and its gas line, then open the windows before calling for emergency repairs.
  • A burning smell can indicate your furnace is overheating or there is a faulty component or exposed wiring that is scorching inside. Again, immediately shut it off and call for repairs.

Aztil Air can help you stay safe with emergency furnace repair services.

7. Difficulty Starting Your Furnace

Have trouble getting your furnace to start or keep running? This could be an issue with your gas furnace ignition system. It could also be a wiring flaw or a thermostat malfunction. A pro can help you diagnose and fix the problem so your furnace provides reliable heating again.

8. Frequent On/Off Cycling

If your furnace cycles on and off often, but not quite short cycling, it could still be a problem. This could indicate an issue with airflow or the thermostat. An inspection can discover why your furnace won’t keep running steadily.

9. Excess Dust or Poor Air Quality

A little dust when you first start your furnace is normal. But if the dust keeps increasing and your home’s indoor air quality drops, this could mean your furnace is not circulating air correctly or cleanly. Florida’s humidity can also cause dust to build up in your ducts and release when the blower runs. Duct cleaning and a furnace inspection can get to the root of the problem and help clear the air inside your home.

10. Carbon Monoxide Detector Alerts

Any home with a gas furnace (gas lines) should have active carbon monoxide detectors. These should be powered and placed near the floor to detect a gas leak that could lead to suffocation inside the home. If a carbon monoxide detector goes off, immediately shut off the furnace, close any gas lines (including the stove or other gas-powered appliances), and open all the windows.

Then call for emergency inspection and repairs.

Excellent job by Niko
Rafael was great. He explained what he was doing throughout his repair
Our air conditioner broke down. We called Atzil and they sent Antonio Moreno over within an hour. He assessed the problem to be a burned out motor and ordered the new one. It was still under warranty. He said it would be in within two days and installed so hopefully that’ll be so and
I will update this when that happens
Dana was excellent!!! Highly recommend him to everyone!
The AC maintenance service was excellent. Niko Garza was professional, helpful, kind, and was instrumental in arranging for the next Senior Technician to solve the AC problem that I am having. That service will be sometime today. He also recommended the dryer vent cleaning and the in-line AC cleaning, of which I scheduled for Monday and paid today. My husband has been very ill for the past 4 years and in the hospital right now. Aztil has arranged the services, after Niko explained the situation, so that they will be completed before he comes home because a patient on oxygen and a feeding tube cannot be without power to the whole house, even a short shut down would endanger him. Thank you Niko!

Technician Rick Cochran did an excellent job replacing the AC breaker and ensuring that everything was in correct working condition. I really appreciated his kindness and professional demeanor. Thank you Rick!

Today Technician Alex Molina completed the services (dryer lint trap cleaning and inline air handler cleaning). Once again, I was fortunate to have a professional, gracious, and thoughtful person come to my house to perform the services. Thank you so much Alex!

If I could leave ten stars I would! Went under an annual contract two years ago and have had just about every service since. Every technician has been great but Ricardo is the absolute best. He and his team were professional and easy to talk to and I learned about the inner workings of the system so I can have a better idea of how to maintain optimum performance. Cleaning the ducts is often a huge mess and I didn’t find a single bit of debris even in the most awkward places. There are few businesses you can just trust and this is one of them.

I’m updating this to say I am still under contract with them and technicians Rafael and Adrian went above and beyond working on a broken motor and cleaning the blower which took hours. Rafael is extremely knowledgeable and patient as he explained several different options available to deal with a 30 year+ dirty duct system. In the end we are going with a duct cleaning plus aero seal which is about half the cost of a full duct replacement. In find them trust worthy.
Response from the owner:We are overjoyed to hear that our service has exceeded your expectations and you would have given us ten stars if possible. Being on an annual contract for the past two years, you have availed a majority of our services and we are pleased to know that every technician has been great but Ricardo stands out as the best. He and his team were professional and easy to communicate with and you were able to learn more about your system and how to maintain it. We are especially pleased to hear that you were impressed with the thoroughness of the cleaning of the ducts, with no debris found even in hard-to-reach areas. We are honored that you consider us as a business you can trust, and we will continue to work hard to earn that trust and provide exceptional service to all of our customers.
Mark O*Connel responded to service my AC unit. He was friendly. Explained what he was going to do. Completed all tasks and gave me some good advice to keep my unit running correctly. Very satisfied with service.
Response from the owner:Hi Kenneth, thank you for your kind words! We're so glad to hear that Marco did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
The technician was wonderful! Curtious, professional and made me feel very comfortable. He explained everything so that I understood it. HIghly recommend this company.
Response from the owner:Hi Sheryl, thank you for your kind words! We're so glad to hear that Aztil did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
Excellent service. Ramon was outstanding
Response from the owner:Hi Anne, thank you for your kind words! We're so glad to hear that Ramon did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
Jordan and Adrian came to clean my a/c ducts and seal my HVAC system. They could not have been nicer, more professional, knowledgeable or polite. They were unbelievably helpful and took the time to explain things so I understood what was going on. I highly recommend Aztil and would request Jordan and Adrian for any future work.
Response from the owner:Hi Julie, thank you for your kind words! We're so glad to hear that Paul did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
This company is excellent. Always there to help you with your air conditioning and heating needs. Lorenzo was the technician very efficient timely and did a great job. Thank you Aztil
