Can I Run My HVAC Without a Filter?

It is possible to run an HVAC system without a filter, but it is not recommended. Doing so will cause the system to suck in debris-laden air and return the same dirty air to the indoor environment, which can lead to health problems. Although it is technically possible to operate without a filter, it is best to wait until you have a replacement filter before doing so. Running the air conditioner without a filter is worse than running it with a dirty one, and can result in colder temperatures, higher energy costs, and even damage to the system.

All heat pumps and ovens have filters, which serve as a barrier to trap dust and debris entering the return duct from reaching the fan. This protects the oven and keeps the air cleaner, since the HVAC system does not recirculate allergens to the air. If your home uses another type of heating system, such as a boiler that uses water to heat the house, you won't have filters. If you notice that your heating bills seem high and your house isn't heating as much as it should, the first thing you should check is your oven filter.

Home Climates offers service settings for HVAC systems so you can maintain the health of your system. We recommend scheduling an oven set-up every fall so you can be sure your oven is in top condition before the colder weather sets in. Even if you decide to wait for maintenance to take place during the winter, oven tuning is still important and useful. Our service technicians can take care of replacing the filters, as well as inspecting the oven and diagnosing any potential problems. Without a filter, dirt and debris are sucked into the air conditioning system and transported back to your home, remaining and accumulating in the HVAC ducts.

Both scenarios can reduce air quality and potentially damage the HVAC system, resulting in costly repairs or replacements. The longer you run your air conditioner without a filter, the more likely it will need repairs. A common problem if you use your air conditioner without a filter is that indoor air quality deteriorates. By trapping these particles within its fibers, the filter keeps them out of the HVAC system, helping to protect your family and your air conditioning equipment. If you don't know where to look or what type of filter you need, it's best to let an experienced HVAC technician do the work for you.
