7 Common Furnace Issues

Furnace issues are a common problem among homeowners. However, many homeowners do not recognize the signs of a faulty furnace. We have created an outline of the seven most common issues homeowners experience when it comes to the operation of their furnaces.

1. Faulty Thermostat

The thermostat is the device that controls the temperature in your home and tells your furnace when to turn on and off. A malfunctioning thermostat is the most common culprit of a faulty furnace. If your fan is constantly running, the battery in your thermostat will drain and cause your furnace to work under capacity.

2. Oddly-Colored Pilot Light

The pilot light in your furnace is a small blue flame needed to light the gas coming out of your main burner. If you notice that your pilot light is a different color, such as yellow, you may have a dangerous amount of carbon monoxide in your furnace. If you notice your pilot light is not blue, call our experienced team of technicians to receive a furnace repair.

3. Cracked Heat Exchanger

Your heat exchanger is a device that transfers thermal energy from one fluid source to another. Heat exchangers can crack if you are constantly overheating your home or slacking on regular air filter replacement.

Unfortunately, replacing a cracked heat exchanger can get costly. Your heat exchanger may be cracked if you’re smelling unusual odors or noticing color changes in the pilot light. Our technicians at 4 Service Pros are on-call 24/7 to help diagnose and resolve your heating issues.

4. Malfunctioning Blower Belt

Your blower belt helps your furnace’s fan run properly. Over time, these belts can fray or break altogether. A tell-tale sign of a broken or malfunctioning blower belt is a shrill squeal emanating from your furnace. Luckily, this is an easy fix. The experts at 4 Service Pros can easily replace your blower belt so you can get back to enjoying an effective furnace.

5. Frequent Cycling

Clogged filters and airflow blockages can cause your furnace to cycle over and over again. A frequent cycling furnace can cause your utility bills to skyrocket, so you must regularly clean your air filters and double-check your temperature settings.

6. Malfunctioning Limit Switch

A limit switch monitors the internal temperature of your furnace. If your limit switch malfunctions or breaks, your furnace won’t be able to regulate its internal temperature and may continually blow when it shouldn’t. Our contractors offer dependable furnace repair services in areas of Virginia such as Annandale, Burke, Sterling, Manassas, Arlington, and Reston. Our team has the tools necessary to fix or replace a defective limit switch in your furnace.

7. Furnace Isn’t Blowing Air

More often than not, a furnace that’s not blowing air can be traced to a dirty blower. Make sure you clear any debris blocking your blower to see if that solves your issue. However, if a red light is flashing on your blower, you need to call a technician to help repair the problem. This red light can mean that you have a problem with your gas valve.

4 Types of Furnace Noises

Odd noises coming from your furnace can be alarming. Sometimes, noises like small popping and chirping sounds can be safe and normal. However, there are four specific noises homeowners should be aware of.

1. Clanging Sounds

Any strange clanging noises coming from your blower compartment generally mean that your blower belt is badly frayed or has completely slipped out of place. The technicians at 4 Service Pros have the tools needed to quickly fix a broken blower belt.

2. Loud Clicking Sounds

Don’t take a loud clicking noise lightly if you hear it. Loud clicking noises can indicate a cracked heat exchanger. Carbon monoxide can escape the cracked heat exchanger, which can be deadly. If you find yourself in this situation, shut off your gas valve and your furnace and call 4 Service Pros immediately.

3. Squealing Noises

While squealing noises can be traced back to a broken blower belt, they can also be a sign of worn or dirty motor bearings. Ignoring the bearings in your motor can result in your system burning out, so it’s important to regularly check and replace them when needed. Our professionals offer innovative furnace services and are committed to helping you maintain the motor in your heating system.

4. Rumbling Noises From Burners

A rumbling sound coming from your burners is typically caused by excessive dirt and grime buildup. This buildup can block your gas jets. Our team at 4 Service Pros can clean and test your burners to ensure your furnace ignites safely every time you need to warm up.
