Does Your HVAC Need a Filter?

An HVAC system can work without a filter, but this is not recommended. Without a filter, the system will suck in debris-laden air and return the same dirty air to your indoor environment, contributing to health problems. Although the answer to this question is yes, your air conditioning system will continue to work without a filter, you should never try to do so. We understand that you may not always have a new replacement filter on hand when you want to replace your current one, but it's best to wait until you have a replacement filter. Running the air conditioner without a filter is worse than running it with a dirty one.

Instead, go to the store as soon as possible for a replacement or call an HVAC professional to have it replaced. Without a filter, your air conditioner risks serious and costly problems. Follow our advice and never run your system without one. Yes, your central air conditioner has a filter. In fact, most central air conditioning units have two or more filters.

These filters clean the air and ensure good air quality as your unit circulates between indoor and outdoor air. In general, it is recommended to have an air filter on each return grille (as long as you choose the one of the correct size and thickness).Filters will improve the air quality in your home and protect HVAC equipment from dust, pollen, pet dander and hair. Yes, all & heat pump ovens have filters. 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, but for an oven or heat pump, a filter is a vital component.

An oven filter serves as a barrier to trap dust and debris entering through the return duct from reaching the fan. This protects your oven and keeps your air cleaner, since your HVAC system doesn't recirculate allergens to the air. 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. 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. The air cleaner is an important addition to your HVAC system because it prevents dirt from accumulating in the condensate and blocking it. We want to spend a little more time talking about the air filter in your HVAC systems because it's extremely important to know what it does and why it's there. Without a filter for your HVAC unit, condensate drain will not be able to do its job of draining moisture and condensate from your system.

Some HVAC systems aren't strong enough to push air through more restrictive filters that block smaller particles, that is, those with a higher MERV or CADR rating, which can reduce airflow and cause your home to heat and cool less efficiently. Needless to say, a filter is an ideal preventive measure to help your HVAC unit operate properly and efficiently. Consult your HVAC system manual to determine the strength of your model or call an HVAC technician. The filter will clog in a few months and will need to be replaced, otherwise it will drastically reduce HVAC energy efficiency. However, you should always consult an HVAC expert or the manual that came with your heating and cooling system to get the right type of filters. Finally, you'll need to consider the dimensions of the vents and spaces your HVAC system is repairing, which will determine the size and thickness of the filter you'll need. If you tend to use your HVAC system all the time, have a lot of family members, some pets, and if you have any respiratory problems, then you should change the filter more often. Filters protect HVAC equipment and capture a large amount of particles that would otherwise end up in the air you breathe.

Proper maintenance of air filters, whether replacing or washing them regularly, is crucial not only to providing clean air in your home but also for maintaining proper functioning of your HVAC system.
