Why You Must Regularly Change Your Air Conditioner’s Air Filter

pleated-air-filterIn Corpus Christi, TX, air conditioning maintenance done each year is essential for an air conditioner’s survival. Both in the short-term and the long-term: it means fewer repair troubles or breakdowns each year, and it means a longer service life with higher efficiency.

Our professionals can take care of this annual maintenance for you (and yes, you do need professionals for the job). But there are a few steps you must take on your own over the summer. One is to regularly change the air filter. We’ve discussed this before and offered advice on how frequently a filter needs to be changed. (There are different types of filters, and the stronger filters need to be changed out less often.) But we want to emphasize how important this task is, especially in a place lie Corpus Christi, where ACs do an immense amount of work over an extended summer season. If a clogged filter is left in place, here are some of the problems it can create:

Damage to motors or other components

The air filter in an HVAC system isn’t there to improve air quality in a house. Its job is to keep the interior of the HVAC system free from the dust and other debris flowing through the return air ducts. But when the filter becomes excessively clogged, it starts to fail at its job. The drag against the filter will cause it to bulge and stretch, allowing debris to sneak in around the sides. Dust on the motors can cause them to age rapidly and burn out. There are many other ways debris can damage the interior of an AC and lead to repair problems.

Iced-over evaporator coil

The warm air pulled in through the filter is run across the evaporator coil of the AC, where heat is removed from it to cool it down before it goes into the living spaces. But, if the filter is clogged up, there won’t be enough warm air moving over the coil, and the refrigerant inside the coil will not warm up past freezing. The cold coil will start to freeze water vapor along it and eventually stop the AC from cooling the air.

Tripped circuit breakers

The blower fan draws the air through the filter and into the HVAC system. The motor that powers the fan will be forced to work harder with a clogged filter, and because this is a powerful motor, that strain can cause a circuit breaker to trip and shut down the air conditioner. Often, a tripped circuit breaker is a major sign it’s time to change the filter.

Sluggish airflow from vents

A clogged filter chokes off the movement of air through the rest of the ventilation system, and this will mean airflow from the vents will drop as well. When you notice rooms that are too hot, check the vents to see if the flow of air is slower than normal. If it is, the filter may be the reason.
