Can I Run a Furnace Without a Filter?

We’ve all been in that situation. You realize you haven’t checked your furnace filter in a long time, and when you do, it’s so full that you can’t face the thought of reinstalling it till you buy a new one. That’s when you’re confronted with this question.

NO is the answer. You can, in theory, run your furnace without a filter. It will work without one, but you’ll risk causing damage to your system, as well as your and your family’s health, and that’s not worth it.

What Are The Dangers of Not Using Filters in Your Furnace?

It will not harm your HVAC system if you operate a furnace without a filter for one night. However, the longer you run your heater services in Murrieta, CA, without an air filter, the more impurities will build up inside the system’s inner workings.

Poor Air Quality

Poor indoor air quality is the most common problem caused by running a furnace without a filter. When a furnace cycles the air in a home, dust is churned up. Debris is sucked back up through the intake, pumped back through the air vents, and suspended in the air until breathed or deposited within the HVAC unit.

Contaminated Duct-Work

Pollutants and air toxins will pass through the ducting without a filter. The debris will collect inside the ductwork, where it will become trapped by the ribbed aluminum tubes. This buildup will trap moisture in the ducting, providing ideal conditions for mold to thrive. Mold spores will begin to flow throughout your home once the HVAC system is turned on, posing a severe health risk to the residents.

System Failure

So far, we’ve concentrated on air quality and health implications, but it’s vital to remember that the fundamental role of a furnace filter is to protect the furnace itself. The inner workings of your furnace can become coated in filth if you don’t have a filter in place to provide that protection. In addition, the evaporator coils or the blower motor may fail due to the increasing tension.

How To Set An Air Filter In Furnace?

You should know how to properly install your furnace repair in Murrieta, CA if you want to avoid filter-related problems with your furnace. Take the following steps:

  • Remove the furnace filter that is currently in place.
  • In the direction indicated by an arrow on the filter label, place the new filter. The arrow indicates the right airflow direction and should be inserted facing the furnace and away from the return duct at all times.
  • You can also use a marker to draw an arrow on the furnace, indicating the filter size and optimum airflow direction for a more straightforward replacement.

It is critical to replace the air filter regularly to ensure that your furnace performs at its best. Even while the method isn’t tough, it can be perplexing if you’ve never done it before.
