Frequently Asked HVAC Questions

Why Can’t I Find My Filter at the Hardware Store?

Some furnaces and air conditioners recommend using an OEM filter designed specifically for the needs of the unit. OEM filters aren’t available just anywhere, which is why offers quality OEM filters and other products manufactured by trusted brands in the HVAC industry.

Hardware Store Availability

Disposable filters are typically what you find at a hardware store. They are typically a lower quality product and don’t offer the same filtration and performance as a manufacturer’s original filter. Some units require a specific filter, which might be hard to find at your local hardware store.

Disposable, low-efficiency filters are cheaper but will have to be replaced more often than a filter that was designed to meet the specifications of your current heating and cooling system. If you notice reduced indoor air quality in your home, it may be due to a cheap disposable filter.

Find a Licensed Dealer for Filter Replacement

A licensed dealer will offer the best replacement filter for your heating and cooling system. They carry OEM, Original Equipment Manufacturer, filters. A filter made by the same manufacturer as your heating or air conditioning system is designed specifically for your unit and its performance.

Several benefits are gained when you install an OEM filter in your system. You will experience greater airflow and lengthen the life of your equipment when the filter fits perfectly. Plus, if you are confused about which filter you need for your furnace or air conditioner, you can speak directly to a knowledgeable professional about which filter you need.
