4 Common and Costly Mistakes When Maintaining HVAC Filters


When it comes to HVAC maintenance, the filter is the component you’ll come into contact with the most. It needs regular attention, as it will eventually clog up due to the buildup of contaminants that are filtered out as the air passes through it. With that in mind, filter replacement leaves little room for error. One mistake could prove to be disastrous for your entire forced-air central HVAC system.

Dependable Heating & Air Conditioning, the local leader in air conditioning maintenance and home heating replacement, warns against making the following mistakes:

Putting Off a Necessary Replacement

How often should you replace your HVAC system’s air filter? It really depends on what the manufacturer recommends, which is generally every three months. However, there are instances when you might have to change it ahead of schedule. Events such as remodeling can increase the amount of dust in the air, which will accelerate the clogging of the filter.

Not replacing a filthy filter in a timely manner might not cause your cooling or heating equipment to fail immediately, but any honest AC or furnace maintenance professional will attest that your HVAC system will break down sooner rather than later.

Reusable vs Disposable Filters

Reusable filters are popular these days, despite the fact that they’re more expensive than disposable ones. Find out if the filter on your current unit can be reused; if it can’t, you can accordingly toss it after changing it out.

Installing an Incorrectly-Sized Filter

Undersized or oversized filters don’t provide a perfect fit. As a result, there will be gaps that allow contaminants in the air to compromise the integrity of the sensitive internal components of your HVAC equipment.

Using an Incompatible Filter

Any trustworthy residential furnace repair technician or AC installer will admit that buying the most efficient air filter doesn’t guarantee optimal performance. Doing so might even cause more harm than good to your equipment. As a general rule, don’t use any filter that your HVAC system doesn’t support.
