Top 10 Reasons Why Your Furnace Is Not Blowing Hot Air

If your furnace has stopped working during the winter, it can be a complete nightmare for many homeowners. To avoid such emergency breakdowns, it is best to have your heating system and furnace maintained by a professional.

This professional maintenance has many benefits. For instance, it will make your system last longer and prevent the need for heating replacement in Atascadero. There might be many reasons the furnace blows cold air, outlined below.

Ten Reasons Which Can Cause Your Furnace To Start Blowing Cold Air.

Thermostat Problems

Sometimes, it is not the furnace’s fault for interrupting your heating. Instead, the real culprit could be your thermostat. There are several thermostat issues that you can solve yourself without needing any professional help, such as:

  • Low battery: Your thermostat will stop working if its batteries are empty.
  • Adjustments: Maybe someone in your home has adjusted the thermostat and lowered the temperature. So check the settings of your thermostat correctly.

Burner Problems

The burner of your furnace is vulnerable to dirt and debris. If it becomes clogged, the fuel won’t get through. Your fan may still operate, but the air it blows will be cold. The solution to this problem is to ensure that your burner is clean.

You can learn how to do this yourself, but the best advice would be to search for a heating service near me online and let a professional perform a thorough cleaning.

Dirty Filters

A dirty or clogged filter might be why the furnace does not blow hot air, as a dirty filter restricts the airflow to the HVAC system. It will make it very difficult for your furnace to produce and distribute warm air inside your home.

Thus replacing the filters is necessary, and the best thing is that you don’t need a professional to do it; you can do it yourself. If you have any doubts, refer to the manual or take help online.

Condensate Line Issues

The condensate requires regular maintenance. While operating in hot weather, the condensing unit of your HVAC continuously drips water into a drip pan. This water is removed and travels outside your home through piping and drains. If these lines get clogged with dirt and debris, your float switch will trip, leading your system to shut down.

Source Problems

Many people often need to remember to check the fuel source of the furnace when the furnace stops blowing hot air. If you are facing problems with your furnace, check the fuel source before calling a professional.

If you have an oil-powered furnace, ensure there is oil in the tank. Check that the switch is on at the breaker panel for electric furnaces. For a gas-powered furnace, ensure the gas supply valve is open.

Leaky Ducts

The ducts carry your warm air throughout the home but are subject to wear and tear over time. The vents are exposed to extreme temperature changes, which can cause weak spots in the ductwork and leaks. If any leak is present, the cold air will get inside the ducts, and the hot air will go out.

Flame Sensor Issues

An old or dirty flame sensor might be the reason behind your furnace blowing cold air. The burner will keep shutting off if the sensor is covered in grime or not working correctly. But the fan will keep working and blow out air instead of hot air.

Pilot Light Problem

If you own a gas-powered furnace in your home, you will notice a pilot light similar to the one on a gas stove. If you have recently gotten maintenance from a gas company or heat pump installation Paso Robles work has been done on the lines, it may be the reason your pilot light goes out. Also, the pilot light often goes out in the case of an older furnace.

Gas Valve Problem

If your gas furnace has not been cleaned for a long time and is covered with dust and debris, then a faulty valve could be a potential reason your furnace is not blowing hot air. Dust and debris can build up on the valve leading to its shutdown. Another reason can be a worn-out valve.

High-Limit Switch Problems

A dirty filter can cause other parts of your heating system to fail. Your system can withstand a few rounds of overheating but repeated overheating will lead to failure of the high limit switch. This switch is necessary for the working of your system, and you don’t want it to fail.

If this switch is not working, your heating system will think that the furnace is overheating, and to solve this, it will start the fan to cool down everything. Unfortunately, this switch is hard to find, and you will need a professional for furnace repair in Paso robles if any such problem arises.

“Let me tell you why this company should have “10” stars. First, you need to know we had attempted to get our forced air heating fixed by another company from Templeton (posted a review on their site). After waiting several days for the other company to return after their initial visit (said they needed to order a part). After many cold days without even a call back we called “Air Rite” in Atascadero. We spoke with Rick (the owner of the company) and explained our dilemma and frustration with our attempt to get it fixed. He understood and said a ...

“Air Rite certainly did right by me! Our 20 year old HVAC system, which had been nursed along for the last few years, finally gave up the ghost. Arne came out and assessed the situation and recommended a reasonably priced replacement system. This morning he sent his team of Cameron, Daniel, David, and Keith, and they went to work. Before 3:00 p.m. on this wickedly hot day in the North County (105°+), they got our new furnace and air conditioning units installed, up, and running. Thank you, Air Rite!”

“We needed to have our AC unit serviced and called Air Rite. The woman who works in the office was attentive and kind. They were really busy because it has been so hot but she let us know the soonest they could send someone out. When the technician arrived he was kind and courteous. He went above and beyond to clean out the leaves that were in our unit and made it ready for summer. Thanks, Air Rite!”
