Furnace season is officially upon us and the temperature is starting to cool down a bit here in Flemington. If you haven’t already fired up your heater this year, you’re probably wondering if it’s going to hold you over until spring. Here at Davis Heating & Cooling, we want to ensure that you’re fully prepared for the coldest months of the year. We’ve already gone over a few helpful tips to save money on heating your home this winter, so let’s take a look at some of the most common furnace problems you may encounter and how to deal with them.

Dirty Air Filters

One of the most common HVAC problems, and possibly one of the easiest to fix is a clogged air filter. Your air filter has no moving parts and isn’t part of the heating process. However, the overall role it plays in the heating and cooling of your home is crucial. The purpose of your air filter is to remove harmful allergens from the air while allowing your HVAC system to run efficiently and circulate air. When it’s clogged, however, your system could be working overtime to circulate air throughout your home.

Replacing an air filter is a pretty simple process, but you’ll need to decide what minimum efficiency reporting value (MERV) rating is best for your home. There are a number of things you should take into consideration to determine what air filter is best for your home, so give us a call if you have any questions.

Damaged Heat Exchanger

A heat exchanger transfers thermal energy from one medium to another. This process is important in order to heat your home. However, if there is a crack in the exchanger not only will your heater not work, but it could be leaking harmful carbon monoxide into your home. We check for heat exchanger damage with each heater inspection.

Ignition Issues

If you have an older heating system, you should check to ensure that your pilot light is still burning. If not, your heating system will not run and you’ll need to relight it. On the other hand, if you have an electrical ignition system, you’ll need to contact us to inspect your system. We’ll be able to diagnose the issue and fix it for you.

Thermostat Problems

When dealing with a malfunctioning heating system, it’s important that you don’t rule out your thermostat. There are a large variety of thermostats on the market from regular thermostats to programmable ones. If your thermostat was installed incorrectly or the electrical components inside of it are not working properly, your whole heating system will not work.

Rapid Cycling Issues

If your furnace is turning off quickly after you’ve turned it on, you may have a rapid cycling issue on your hands. Although this could be caused by a clogged air filter as we mentioned earlier, it’s most likely a problem with the blower motor and belts which will require professional service to repair.

Noisy Furnace

Although it may seem normal for a furnace or ductwork to be noisy, it’s usually a sign that something is wrong. If the noise is coming from the furnace itself, it could be a mechanical issue or a clogged burner. However, if it’s coming from the ducts, it could be the sign of dirty air ducts or a loose component. Although a noisy heater isn’t always a problem, it’s usually best to get in contact with an HVAC specialist to inspect your system.

Dirty Flame Sensor

The flame sensor is in charge of identifying the unsafe burning of fuel. If the flame sensor is dirty, it won’t just prevent your system from working properly, it could be a huge safety issue. The flame sensor can usually be located near the back of the furnace near the burner.
