Most Prevalent 05 Furnace Issues With Solutions

Sometimes, a minor problem with your furnace can prevent it from working correctly and lead to frequent visits to a nearby gas furnace repair shop in St. Simons Island. Here are some of the most common issues you can encounter with your furnace and their fixes.

1. Furnace Produces Zero Heat

During the winter, the furnace’s job is to produce heat that keeps your inside area warm. If it is unable to accomplish this, there is a severe issue. However, why is your furnace not heating up? The gas furnace repair experts in St. Simons Island suggest several causes; the most common is a malfunctioning thermostat. Your furnace won’t provide heat if your thermostat is off.

If you are unsure whether the thermostat is the issue, try adjusting it a few degrees.  If there are no apparent changes, you can investigate if the circuit breaker has tripped, as this can potentially be the source of the issue.

2. Short Cycling

As each heating cycle is over, the furnace is meant to switch off and on after a short while. It is to keep the house at the appropriate temperatures (as specified by the thermostat) without being too hot.

When on-and-off cycles become too frequent, it indicates that the furnace isn’t finishing the heating cycle.  An average furnace will run through two to three cycles every hour, each lasting around 15 minutes. Short cycling can cause your furnace to go on and off every 1-10 minutes.

The furnace can not finish the intended heating cycles for several reasons; however, here are some fixes to try: 

• Replace the filter if the furnace filter becomes dirty after two to five-minute cycles.
• Install a replacement sensor in its place. 
• Open approximately 75% of the vents.
• Purchase the appropriate furnace size for your home.
• Remove anything obstructing the exhaust vent.

Regular furnace maintenance by gas furnace repair pros in St. Simons Island can avoid most of these problems.

3. Noisy Furnace

While some furnaces make very little noise while running, some do make more unsettling noises. If there is an issue with the furnace, this noise can become louder and more apparent.

Among the noises that can point to heating issues are the following:

• Squealing Noise: A worn-out belt that has to be replaced is typically the cause of this kind of noise. 
• Grinding Noises: They are signs of worn-out bearings. Get a gas furnace repair specialist in St. Simons Island to replace them if you lack the necessary skills.
• Knocking Or Tattling Noises: Your heater can make these noises due to loose fasteners or exposed panels.

It’s recommended to contact an HVAC specialist if your furnace is making any of these strange noises. A specialist can assist you with furnace repairs and quickly diagnose the issue.

4. Furnace Can’t Turn On Automatically

Generally speaking, when you adjust the thermostat, a well-operating furnace should start immediately. If not, there appears to be a problem.

A furnace that isn’t turning on can have several underlying problems. Depending on how severe the issue is, it can be something you can fix or need to be handled by a professional gas furnace repairer in St. Simons Island, like Superior Air Management (St. Simons).

All you have to do is restart the furnace and flip the circuit breaker switch on. Your furnace won’t start or cool your home if the thermostat settings are high. Thus, also turn down the thermostat.

Other problems that can keep your furnace from starting up include the following:

• Faulty ignition or pilot light
• Air filter clogged 
• Fuel

5. Blower Not Turning Off

The blower’s purpose is to help direct the heat the heater produces to the appropriate areas of the house. But it doesn’t always function. After some time, it is meant to switch off and then turn back on.

There is an issue if the procedure doesn’t go this way and the blower continues to blast.

The first step in fixing this problem is to adjust the thermostat’s settings by selecting “On” rather than “Auto.” Try lowering the thermostat’s temperature settings to see if it resolves the problem if none of the above solutions work.

There are other possible reasons why the blower is not stopping, such as a thermostat that is worn out or a malfunctioning fan limit control switch. You must consult an expert gas furnace repair shop in St. Simons Island to resolve any of these problems.
