Furnace Repair Fort Worth

Fort Worth, Texas, is a big city with humble beginnings first as a fort and then as a ranching town. Just outside the city, you can still see lots of open farmland and ranches with longhorn cattle roaming the fields. From tumbleweeds to cowboy boots, Texas represents good, old-fashioned American values and roots.

Fort Worth can also get incredibly hot in the summertime, and in the winter time, it sees its fair share of cold nights and chilly days — days that make us Texans who are used to the summer heat just want to go home to our nice warm homes and curl up in blankets with our cat, dog, and a good book. Thus, for those days when you don’t want to leave your home cause of the wind and cold, you need a top-notch furnace to keep you warm. And when your furnace is not working, it can make for a not-so-happy start to your day.

Dirty Filters

Believe it or not, there’s a reason you need to regularly change your furnace filters — so your furnace will continue to operate. The problem that dirty air filters cause furnaces is that they slow down airflow. This makes your furnace work harder than it normally would have to. It also can cause the limit switch to not function properly, which is what controls the fan that blows the hot air into your home.

Thermostat Having a Bad Day

If your thermostat decides to not cooperate, your furnace won’t work properly. There are a variety of problems with your thermostat that can affect your furnace. The battery could be low or dead. The fan setting could be perpetually in the “on” mode, which would drain your battery. Or, the thermostat could be near the end of its life, which would cause it to not operate properly.

Faulty Pilot Light

The purpose of a pilot light is to ignite the gas when your furnace turns on that will then power the gas burner. The pilot light is perpetually lit by allowing a small amount of gas to come up through a gas pipe into a tube. However, the safety problem comes from the fact that if your pilot light ever blew out, gas would keep coming through, filling your home. This gas could ignite and cause an explosion.

Luckily, a very small pilot light sensor, called the “thermocouple,” was invented and installed on furnaces. This thermocouple generates electricity from the heat of the pilot light. When the pilot light goes out, the thermocouple, which is attached to a valve, loses heat and shuts the valve it is attached to. To relight the pilot light, you have to manually do so. You have to light the pilot and then wait for the thermocouple to heat up and then you can let go of the button.

Because a constantly running pilot light wastes gas, modern furnaces use something called a piezoelectric spark to light the burner instead. This is how push-button igniters work. Certain natural crystals like quartz can create a voltage when hit. Similar to a spark plug, this pressure generates a spark that then ignites the gas.

A faulty pilot light could be a broken or loose thermocouple or a clogging around the pilot light, such as a piece of wiring in the way. The setting could be off as well. Either way, a professional furnace repair technician in Fort Worth will need to take a look, such as Arthur Hagar.

Blower Not Functioning

Sometimes the blower is not delivering heat to your home. Sometimes a fix is as simple as ensuring the door is shut. Most likely, the blower belt is off, either it’s worn and needs to be replaced, or it’s cracked and broken. Replacing a belt to your furnace is not as simple as it seems, and blower motors can get really hot. If your blower motor is really hot, it could be a sign of an overload, which would require the blower motor to be replaced, which is a job for a professional HVAC specialist.

Electrical Problems

Electrical problems with your furnace are common, but these are easily missed by homeowners because they are not noticeable. For instance, you can see that your pilot light is out. For an electrical problem, there are not obvious outward signs of such. Oftentimes, it’s a blown fuse or a tripped breaker, so check your electrical breaker box and replace the fuse and/or fix the breaker. If this still does not fix your furnace, call for local furnace repair in Fort Worth today.


Like all pieces of machinery, your furnace can be broken. This can be caused by normal wear and tear issues that can affect the airflow, overheating, or a variety of other issues that a professional HVAC technician from Arthur Hagar would have to diagnose. It could also be caused by a lack of maintenance as well. You should have an annual furnace check performed once a year in order to fend off any major repairs that occur from minor fixes.

Many of us tend to forget about our furnaces until they are needed. When they are needed, we turn them on and when no heat comes out, then we realize we have a furnace problem. Above, we’ve listed the most common furnace repairs we see — many of which you can try to DIY repair. Some other furnace repairs to try include:

  • See if your furnace has power. Some furnaces have switches to turn them on.
  • Reset the motor. Many furnaces motor overloads, and many have reset buttons you can push similar to your WiFi reset button on your router. You simply press it and see if your furnace is happy again. If not, our furnace repair technicians are standing by.
  • Make sure your gas valve is on. Many homeowners turn these off to conserve energy during the summer months. Without gas, you can’t have heat!

Many people think of their heating system as an afterthought here in Fort Worth since air conditioning is the primary need. However, there are winters where it gets cold and the snow falls heavily. Most winters are quite chilly, and a good working furnace system is an absolute must. By having your furnace regularly inspected and maintained, it will be ready for when you need it. Some people make the mistake of turning on their furnace after nine months of not using it and realizing it needs a furnace repair, leaving you in the cold until we can get to you.

Our residential and commercial furnace repair technicians offer clean and checks to keep your furnace well maintained. Here, we’ll perform routine maintenance on your HVAC system as a whole, such as cleaning, changing filters, adding refrigerant, and repairing any minor issues we might find, such as cracking or a worn out fan blade or blower so that your heating and cooling will work when you need it to.
