Dec 17, 2021 | Bexley, Blog, Furnace, Heating, HVAC, Maintenance, OH, Ohio, Winter

As a homeowner, spending money on home heating and cooling systems often feels like buying tires. You know your car needs them, but you don’t want to dish out the money to buy them.  However, depending on how well you take care of your heating system, you could need repairs or a complete replacement. Unfortunately, unlike buying tires, too many homeowners wait until their heating and cooling systems fail before doing anything. We don’t want our customers to make this mistake, so our high-quality technicians at Bexley Heating & Cooling compiled together a list of common questions most homeowners have when it comes to their residential furnace. 

1. Why is My Furnace Not Lighting?

If your furnace has an electronic igniter, you will need to find the reset button and try turning it off and then back on. If all fails after resetting it, you’ll need to contact one of our professional technicians at Bexley Heating & Cooling to schedule an appointment as soon as possible  

2. Why Does the Blower Keep Running? 

Not only can blower issues run up your home’s energy bill, but they can also indicate a severe problem with the unit’s limit switch. The limit switch is located inside the systems panel door on most furnaces. Keep in mind; There are two main reasons why your blower is continually running: First, your thermostat. This may seem like a no-brainer, but our experts suggest you check your thermostat’s settings to ensure all things are set correctly. Secondly, the fans limit switch could be turned on “continuous” mode. If either of these things is set incorrectly, correct them and closely monitor your furnace. 

3. Why is my Furnace Tripping the Breaker? 

This means that your blower is overworking itself. This can happen if your air filter is dirty or clogged, thus causing a blockage in the airway of your home heating system. When your blower is working overtime, it causes the circuit and the energy consumption of your furnace to increase, which can trip the breaker. Before you contact a professional, you should change your air filter and check all vents are open for optimal airflow.   

4. Why Doesn’t My Furnace Get Enough Heat?  

More often than not, the cause of this is a clogged filter. So, to keep up with your system’s preventative maintenance, make sure to frequently check and replace your air filter at least once every three months or as needed. On top of that, be sure to schedule your annual tune-up and safety check. 

5. Why Is My Furnace Making a Loud Noise & Shaking? 

Loud noises are not a good sign. Hearing loud noises such as buzzing, humming, screeching, or rattling coming from your home heating system is never a good sign. Hearing any of these noises could be due to various issues like incorrect blower assembly, loose parts, and screws, a bad belt, or leaky ductwork.
