What Are The Most Common Furnace Problems?

A broken furnace is one of the most frustrating things a homeowner can face. But, unfortunately, we all have to deal with heating system maintenance issues at some point in their whole working life cycle. Although you should get your furnace serviced as soon as possible if it stops working, meanwhile there are a few things you can look for to diagnose problems early on, potentially saving you money on a replacement or an even more costly repair. If the problem persists, you can reach out to Miles Mechanicals AC and heating for the best heating service in Garland.

We have prepared a list of the most common furnace problems that you may face along with a few solutions you could try on your own:

  1. Dirty & Clogged Filters
    Filters that are unclean or blocked can restrict the amount of air your furnace receives, lowering its efficiency. It’s also possible that your limit switch will be damaged as a result. Replace your filters at least once in 2 months to maintain the best performance.
  2. Issues in Thermostat
    A broken thermostat is among the most prevalent furnace issues that a homeowner can face. If your fan is always running, it’s a clear sign that your thermostat isn’t working properly. Because of this, your thermostat battery will run continuously and your furnace will perform inefficiently. Set the fan to automatic mode and see whether it runs continuously at all temperature levels to see if this is the case.

  3. Strange noises
    If your furnace is making cracking, tapping, or grinding sounds, a lot of factors could be at blame. The most common cause of grinding noises is loosened panels on the heater that need to be fastened. The ductwork is most likely the source of cracking or tapping sounds. It will expand or contract depending on whether you are heating or cooling your home.

  4. Faulty Limit switch
     If the limit switch of your furnace isn’t working properly, your furnace may continue to blow even when it shouldn’t. Unfortunately, changing this will need the services of a qualified mechanic. Mile Mechanic HVAC can help you with heating repair in garland.

  5. No air blowing
     This problem could be caused by a number of factors. The most important thing is to keep your blower free of dirt to avoid it getting blocked. Next, check to see if your blower has a flashing light. If it’s flashing red, you’ll probably need to contact an expert for assistance.

  6. Loose ball bearings
    The ball bearings in your furnace aid in the efficient operation of the motor. Unfortunately, they can deteriorate over time and need to be replaced. If you hear a scratching noise coming from the furnace, shut it off right away and call an HVAC technician, the best heating service in garland.
