How Often Should I Change The Filter on my Heating System?

If you are wondering whether it really makes a difference whether or not you change the filter on your heating system, the answer is yes, it is important. When it comes to ensuring the health of your heating system, it is important to maintain it properly, and changing the filter is one of the simplest ways to do so.

Changing the filter on your heating system helps prevent problems and increases both the life and efficiency of your equipment. Dirty filters can cause your system to get inadequate airflow, causing the hating equipment to trap heat and overheat. This is not healthy for your equipment. A dirty filter can also cause short cycling, making the equipment engage and disengage too quickly and too many times. A filter that needs replacing can also cause poor air quality because air has to run through a filter that can no longer trap allergens and debris.

Richard's Heating & Air Conditioning Co., Inc. Can Estimate When Your Filter Needs Repair

So how often should you replace your filter? Most manufacturers and HVAC pros recommend changing it every 1-3 months. Now, that is a bit of a difference in time. Once a month equates to 12 times per year, while every three months means only 4 times per year. So how do you know which is best? You can learn what is best for your household over time by checking the filter every month and seeing whether it is dirty or not. If you hold the heating system filter up to the light and can’t see much of anything through it, it needs to be replaced. After a year or so, you will have a pretty good idea how long it takes for your filter to get dirty and needs to be replaced.

TESTIMONIALS & REVIEWS

Great experience with Richard’s – my furnace was off line due to a previous contractor’s poor electrical wiring, and they found and corrected the problem in a matter of minutes. Very responsive, and the work was done at a very fair price. I recommend Richard’s without hesitation.
