Regularly changing the HVAC Air filters in your air conditioner or HVAC system will keep your equipment in good working order and keep your electric bills as low as possible. It’s also something many home and business owners forget to do year-round. This can send your bill into the stratosphere and cause other maintenance issues. Read on to find out the recommended filter change frequency!
General recommendations
The key question here is how often should the filters in the appliance need to be replaced? The short answer is:
According to usual recommendations, they are for cheap filters every 30 days and for high-quality filters every six months. These estimated frequencies are for average use and will vary depending on filter type/size.
A general rule of thumb for pleated air filters is to replace them every 90 days. The more dust and dirt the filter collects in the air, the less effective it will be. Check if the filter needs to be replaced more often in the next section.
Does anyone in your accommodation have breathing difficulties or allergies?
People with respiratory problems, such as asthma, are much more sensitive to airborne particles than they are. If you have someone in your building which suffers from this living or working condition, replace the filter every six weeks to optimize the air quality.
Are there animals on site?
Animals such as dogs and cats create odors around your facility, so changing the filter every two months is important. Dogs and cats typically shed most of their hair just before spring and just before fall. This is the perfect time to replace the filter.
Are there young or older people in the facility?
Good air quality is essential for young children and the elderly. Keep your building clean and manage air quality by replacing all filters every 2-3 months.
Factors that reduce the life of HVAC air cleaners:
Frequency of using HVAC equipment
If the country you live in (such as the UK) has a temperate climate and he uses the air conditioner for only a few hours a day, one air filter will last him from one season to a year. If your HVAC system runs 24/7, you’ll need to replace your filters every few weeks, especially if you’re using cheap or poor-quality filters.
Building size
Air conditioners in tiny homes and buildings need to pump less air for the exact change in temperature, so filters may need to be changed less frequently. However, these units often have smaller filters that may need to be replaced as often as larger building filters.
Air quality in your home or building
The air inside and outside the building is an important factor in filter replacement frequency. For example, pets and poor air quality mean that air filters need to be replaced more often during the season.
How to know when to change your HVAC air filter
Every time you use your gear, a lot of dirt builds up in your air filter.
So what’s the best way to know when your filter has gotten too dirty and needs to be replaced?
There are no hard and fast guidelines, but if there is only a thin layer of dirt under the filter and the filter material is still visible, the filter is in good working order. After that point, it will be ready for replacement. If there is evidence of a visible layer of dirt covering most of the filter surface and thick enough to obscure the filter material, this indicates that the filter has been in his HVAC system for a long time. I’m here.
Please take out the filter and check it every few weeks. Do you have a musty smell? Is dust accumulated in the filter? If you’re unsure, it’s a good idea to replace the filter proactively. They’re relatively cheap to buy, there are always great deals online, and the small cost of keeping your vents clean can add to your electric bill. It’s been a long time since you last changed the filter. If so, we can help you find the right brand and size for your air conditioning or HVAC system type.
