How to Avoid Common Furnace Issues This Winter

Your heating system is pretty much the sole thing that stands between your family and a life-threatening bout of cold this winter. Minimizing service interruptions is a high priority. But it’s not just all-out failure to perform that can render a furnace problematic during the cold months. Quite a few issues stemming from the unit’s increased use can lead to costly repair issues in the spring and increased system wear.

Furnace Doctors, as a team of HVAC contractors, cares about your family’s comfort and safety. So here are a few furnace issues commonly brought about by winter wear, and how to avoid them.

A Dirty Heating System Filter

If any part of your heating system starts acting finicky, the filter is the first part you should check. Because homes don’t get much fresh air in the winter, filters can get dirty quickly, thanks to the cold. This becomes detrimental when air struggles to pass through the filter because of dust and debris.

In turn, your heating system has to work harder to compensate. As a result, the furnace repair will probably be much more complex than a simple filter change.

The best way to prevent this all-too-common problem? Check your furnace filter monthly.

While some filter types can go months without needing to be changed, others must be disposed of every thirty days. If you are concerned about your furnace’s filter, consult the manual for your unit or speak to an HVAC professional.

A Noisy Heating System

We’ve already talked about cooling and noise in our air conditioning contractor blog, Why Is My A/C Making So Much Noise? So perhaps it’s no surprise that heating plays by the same rules: it shouldn’t make a sound.

When it does, you can generally discern the problem by which sounds you hear from your unit. It’s helpful to think of noise as a symptom rather than a problem in and of itself. Though the noise is certainly irritating, it never happens unless something mechanical is seriously wrong.

For example, a buzzing noise can indicate that there is debris stuck in your unit, and a persistent rattle noise may be telling you that a critical piece is loose. What exactly the problem is can vary widely, it often gets worse with the system’s increased cold-weather use.

The best prevention, in any case, is a seasonal maintenance plan that addresses just as wide a variety of furnace parts.

A Furnace That Fails to Light

Often regarded as rock-bottom when it comes to heating issues, if your furnace won’t turn on, time is of the essence. Whether or not it can be fixed depends on how soon you get an HVAC expert over to your home.

However, a furnace with a pilot light that goes out is a preventable problem. With a season maintenance plan, all possible causes of a failing pilot light can be found before they cause serious damage, such as the necessity of new furnace installation.

While you wait for a professional to arrive so you can fix the problem and schedule routine maintenance, consider the filter. Changing the filter in your furnace is a great and simple way to fight debris accumulation and service interruptions.

If you have concerns about your filter, discuss them with an HVAC expert!

Faulty or Mismatched Thermostat

A faulty thermostat causes some of the most common signs of a furnace acting up. These include wild temperature swings, no heat production, or frequently cycling.

Often, you will look into other reasons before coming to the conclusion that it is likely your thermostat. There may be dust and debris in the thermostat itself, causing it to power off or on prematurely. If you’ve cleaned your home’s thermostat and are still experiencing these issues, connect with a furnace expert because it may be the wrong type for your system.

It is important that, when you have a new furnace installed, that your thermostat matches. Pairing the wrong types together offers up operating problems, such as underheating and overheating.

A Furnace That Cycles Too Quickly

If you’ve noticed that your furnace is cycling frequently while producing little to no heat, you may have a problem with the electronic ignition. Signs that your furnace’s electronic ignitions also include having an overactive blower.

When your furnace’s electronic ignition is failing, your system won’t heat your home or will do so intermittently and, then, it may as well not be doing it at all.

Experiencing a furnace that cycles too quickly or doesn’t heat your home during the winter months is far more than an inconvenience. If you notice any of these signs or feel as if your furnace isn’t heating your home properly, speak to a furnace expert.
