Why Is My Furnace Not Working in Silver Springs, FL?

After toying with the thermostat or standing near your heating unit to listen for odd noises, you ask aloud, “Why is my furnace not working?” You’re facing a damp, chilly January night without heating. There’s nothing worse than feeling the cool, moist air seep into your home. 

Fast Air Heating & Cooling has gained plenty of professional experience as the go-to for heating repair in Silver Springs, FL. Below, we share our insights into your furnace’s lackluster performance. You might employ some of our recommendations or contact us with a more technical issue. 

Making Your Furnace Work Again in Silver Springs, Florida

First, let’s cover the issues you can probably handle on your own. Sometimes, you just need to tidy or adjust an accessible component. Go through this checklist to see whether these solutions fix your silent furnace. 

Dirty Pilot Light

The pilot light is a small flame that stays lit whether your furnace cycles or not. This little flame ignites the fuel as it moves into the burner. The ignition produces enough heat to warm your home or business. 

Pilot light issues are fairly common and easy to remedy. If you remove the furnace panel, you can find the pilot light near the bottom. If you feel comfortable doing so, carefully remove this part and wipe it down with a clean microfiber cloth.

This should eliminate fine ash and dirt and enable the pilot light to ignite. You might also check the nearby flame sensor, which can also become dirty. Check your furnace user manual for details from the manufacturer. 

Filthy Air Filter

Clogged air filters can cause big problems that thwart your furnace’s performance. Fortunately, you can just remove and replace the old one. Many HVAC technicians suggest replacing it every three months. 

Consider more frequent replacements when:

• You own pets.
• You smoke or vape indoors. 
• You have a dusty home. 
• You enjoy hobbies or have other habits that might add to airborne debris.

Dirty filters increase air resistance when the furnace draws air through the return register. Too much resistance can trigger a shutdown.

Offline Thermostat

Sometimes, a simple thermostat malfunction causes big comfort problems. Check that your device has:

• Fresh batteries
• Secure wire connections
• The correct settings

One of these three solutions could make the heat flow freely again. 

Obstacles in Front of or Inside Vents

Each room or section of your home has a vent that delivers warm air into that particular area. Blocked vents or ducts prevent air from circulating into their respective rooms. 

Plus, the obstacle can also create air resistance, which may trigger a shutdown, much like a filthy filter. Inspect every visible vent for:

• Dust-coated grates
• Items inside the ducts just within reach
• Laundry piles, furniture, and other belongings blocking them

Free each opening of dust, debris, and blockages to enable the airflow. If you’ve gone through each recommendation above and still wonder, “Why is my furnace not working?” you should contact a local HVAC company for assistance. 

Problems That Require Help From a Technician

Sometimes, homeowners might have furnace problems that only experienced technicians in Silver Springs, Florida, can tackle. We’ll elaborate on such concerns below. A provider like Fast Air Heating & Cooling can quickly dispatch an HVAC technician to your address to fix them. 

Damaged Ignition

Some ignition problems develop because of run-of-the-mill dirt buildup. Others happen when the parts incur damage of some sort. Pilot lights, flame sensors, and connected pieces can become corroded, cracked, or shorted. You can affordably replace these parts to get your furnace running again.

Old Blower Motor

“Why is my furnace not working?” you ask upon learning that simple ignition fixes won’t cut it.  

You might have a blower motor failure on your hands instead. The blower motor draws in and pushes air over the heat exchanger. The exchanger then warms the air before it moves through the duct network. 

What kinds of problems might a faulty blower motor cause?

• It can overheat from dirt and grime.
• Its connection with the control board may loosen.
• It can blow a fuse.

A technician can fix many problems quickly. However, some issues require a full replacement, which can cost nearly $1,000, depending on your furnace unit. 

Cracked Heat Exchanger

“Why is my furnace not working?” you repeat after learning the blower motor works just fine. 

As briefly mentioned above, the heat exchanger plays an essential role in the furnace’s heating process. These components typically last as long as the units themselves. But they sometimes crack, which means no heat. A cracked exchanger can also endanger your home or business in Silver Springs, Florida. 

Unfortunately, broken exchangers are expensive to replace. You might as well budget for a complete furnace replacement and discuss financing options with your technician. 

Poor Fuel Connections

Your furnace may also stop working because it doesn’t have enough fuel. Check your fuel gauge to see if you need a top-off from your local fuel provider. If the gauge shows you still have a reasonable supply, the fuel line may be leaking or is disconnected.

Line blockages, damaged valves, and broken lines can prevent adequate gas, oil, or propane from powering your furnace. These issues can also endanger you and other building occupants. A qualified HVAC technician should inspect and repair the line to protect your property. 

How to Prevent Furnace Failures in Silver Springs, Florida

Consistent inspections and maintenance efforts can keep breakdowns and avoidable wear and tear at bay. Work with your HVAC technician to come up with a plan that works for your property. You’ll find recommendations from Fast Air Heating & Cooling below. 

Self Maintenance

Take a look at this troubleshooting guide to learn what to look for when inspecting your HVAC system. It addresses a few common problems and solutions you can apply. You should also perform quarterly HVAC maintenance that consists of:

• Filter replacements
• Vent cleanings
• Unit inspections and cleanings
• Battery checks and replacements for the thermostat
• Airflow tests
• Utility bill analyses
• Cleaning small parts, you can easily access and put back

You should also try to curtail your HVAC usage where possible to limit age-related damage. For example, keep winter temperature settings between 65 and 69 degrees Fahrenheit, and use space heaters when you stay in a single room. These efforts protect your furnace from overuse while keeping your utility bills affordable. 

Professional Maintenance

You can’t skip tune-ups, even when you stay on top of your maintenance duties. A seasoned HVAC technician knows to look for hidden concerns that might slip past you. Plus, they can tackle other tasks, such as:

• Cleaning delicate components: They’ll wipe down the flame sensor, pilot light, and other parts prone to dust or ash buildup. 
• Lubricating or adjusting moving parts: Gears, fan blades, and other mechanical pieces need some grease to move smoothly. Your technician will also ensure security and movability. 
• Testing system performance and safety: Some providers test the system’s voltage and fuel usage before making sure each safety feature responds as expected. 
• Inspecting for internal damage: You can see external wear and tear, but your technician can access the internal components for a once-over. 
• Repairing small HVAC problems: If your technician encounters a damaged belt or a faulty wire, they may go ahead and replace them. 
• Calibrating the thermostat: Tune-ups also include thermostat calibration to enhance its temperature detection and responses.
