Getting the right temperature is essential for comfort. However, despite wearing your coziest socks and wearing your favorite scarf around your neck and shoulders, it can sometimes be hard to miss that unmistakable chill that leaves you shivering.

This is where furnaces come in handy – they’re much cleaner, and  they’re far better at warming up your home than an old-timey fireplace. So when it stops working, it’s important to know what you need to do if you need furnace repair in Troy.


Most Common Furnace Problems

Dirty Filters

If your furnace isn’t blowing heat like it usually does, the first thing you need to do is check if your filters aren’t clogged up by any dirt or debris.

Dirty filters are usually the culprit behind any inefficiently heating furnace. Air filters can trap dust and dirt, which not only affects your furnace’s performance but can also affect your air quality over time.

To fix the issue, all you need to do is get new filters and follow the manufacturer’s manual to replace them. Most hardware stores sell filters for cheap, and the recommended time for changing filters is once every three months.

Noisy Furnace

While most furnaces make some noise when they’re running, some noises are definite signs that something’s up.

Normally, you’ll hear clicks once your thermostat reaches a certain temperature. The thermostat sends a signal to the furnace, followed by a whir as air is pumped out through the ducts and out the blower. Depending on the model, some blowers are louder than others.

However, knocking and rattling noises may mean a problem that could get worse if you leave it unchecked. Before you call in a professional for any serious issues, start with simple solutions like replacing the filter, unclogging the air ducts, or oiling the blower motor.

Here are other things to consider trying when you hear noises you shouldn’t:

  • Grinding or scraping noises – This can indicate worn-out ball bearings, which should be replaced immediately.
  • Shrieking noises – This can mean that your blower belt has either slipped or worn out. If there is no damage, you can tighten the blower belt or replace it if there is damage.


Faulty Thermostat

Many malfunctions can be caused by a faulty thermostat. Thermostats are the main control panel for your furnace, and a faulty one can lead to issues with the fan. You can start troubleshooting by setting the thermostat to heating rather than cooling, then setting it to five degrees above room temperature.

If it’s not working normally, it may just be the thermostat’s batteries that need to be replaced. Since dead batteries can cause the display to go blank, it’s important to always have spares to replace the old ones, which you should do once a year.


Leaking Water

Furnaces can sometimes develop condensation leaks. When droplets of water pool around the furnace, rust can form and reduce its overall efficiency.

These days, most high-efficiency furnaces use PVC pipes rather than metal ones, especially those with cooling features. On top of this, they also have separate pipes for any condensation to drain away.

If you start seeing droplets pool around your furnace, it’s best to see a professional get it fixed as soon as possible.


Frequent Cycling

Furnaces typically cycle on and off when heating your home, depending on the temperature set by the thermostat. Depending on both the outdoor and the set temperature, it can cycle on and off several times in an hour.

However, frequent cycling without achieving the set temperature usually means something’s wrong.

In the case of short cycles, the furnace can run for a few minutes before shutting off. This can be caused by a limited airflow, which is a usual culprit for overheating. When this happens, the built-in safety switches kick in and shut the furnace down.


Furnace Doesn’t Turn On

All furnaces have a set power switch. After maintenance, it’s always best to make sure to switch on the furnace to make sure it’s working properly. You can find the standard wall switch on or near the furnace to do so.

On top of that, you also want to check your circuit breaker to see if it’s been set in place, as well as the front panel covering the blower motor. If your furnace still isn’t turning on, make sure the push-in switch under the panel is fully depressed.


Faulty Air Ducts

In the case of cold spots in your home when the heating comes on, the problem could be caused by leaking or incorrectly designed air ducts. You can try adjusting the handles protruding from the ducts if this is the case since these are built-in dampers meant to control airflow. By making sure they are fully open, you allow the air to flow and reach the temperature set by your thermostat.

However, if certain areas or rooms are still cold, this may be a problem with leaking or blocked air ducts; the former you can seal with special metal duct tape. For other problems, such as restricted airflow, you should also make sure your vents aren’t obstructed by any furniture or objects in your home, such as shelves, drapes, or wall art, which can reduce the overall heating efficiency.

Do You Need Furnace Repair in Troy?

When everything is going well with your heating, you can keep your temperature at home at a stable, comfortable level set just to your liking. While you may not notice it, furnaces operate in the background and do the heavy lifting for your comfort.

However, furnaces also come with issues of their own. Even though they are designed to work for life, they will still need regular maintenance, and parts will sometimes need replacing from time to time.

Problems with your furnace can take all forms. Some are minor issues that you can repair by yourself (with a little elbow grease and duct tape in the right places), while others can be a little trickier.
