Being a responsible homeowner, you are regular with your air conditioning service regimen. You have company trained professionals come over for your AC’s annual maintenance. But an annual maintenance is not always enough for your air conditioner. You also need to have its filter changed every 1-3 months, based on how often and how long you use your AC.
This is very important because a dirty air filter in the HVAC system only creates more problems than remedies to the system. You will realize it’s importance only if you first realize why you need a filter in your HVAC unit in the first place.
Improves the functioning of your AC unit
You, like most people, assume that the air conditioners air filter maintains the air quality in your home. However, you are wrong because while air filtration does help boost the indoor air quality, it is not efficient enough to do it effectively.
Now the next question that comes to mind is that if the filter is not primarily responsible for boosting indoor air quality, what is its use? Well, these air filters help prevent the accumulation of any dust and dirt in the AC, which only ends up compromising on the air conditioners functioning. This means that if the filter is dirty, it will not help much in preventing this, and in turn create new air conditioner problems.
Reduces energy costs
A dirty filter means that your HVAC faces increased airflow resistance, which in turn increases your energy costs. There is no point in paying extra to cool down your home if the culprit is nothing but a dirty filter.
In fact, dirtier filters mean that your air conditioner has to use more energy to force air through it. Not only does this lead to increased energy expenditure, but also leads to air going around the filter while taking all the pollutants it has to actually remove. This, in turn, leads to reduced indoor air quality.
Prevents AC from short cycling
The short bursts you find your air conditioner running at instead of running at even and full cycles are usually due to the air conditioner overheating because of the extra strain the dirty filter puts on it.
This is why your air conditioner automatically shuts down to prevent possible damages. This is also why your technician changes the air filter during air conditioning service because the unit’s efficiency levels only drop if the problem is not taken care of.
Improved cooling efficiency
Last but not least, the most important reason and benefit of changing a dirty air filter are because it helps increase the air conditioner’s cooling efficiency.
With so many reasons and benefits associated with changing air filters a few times a year, including during air conditioning service, it is always better to stock up on the right replacement air filter for your system. This will help reap so many benefits for you which includes improved performance, increased energy efficiency and reduced energy costs in your AC functioning.
