Why is Changing Your Air Filter So Important?

A finger with dust on it

September brings delectably cooler temperatures in the evenings and early mornings, but we can still find ourselves with 80 to 90-degree weather on many a September afternoon. We may still be wearing shorts and flip flops and spending time in the pool in the afternoon to keep cool instead of running the air conditioner. When the temperatures are mild, your air filter is hardly used at all. Has the thought of changing your air filter crossed your mind recently?

The Importance of Changing Your Air Filter

Air filters are often under-appreciated, but they are an important part of your central HVAC system. They prevent larger objects from being pulled into the system where they could cause damage or even a fire. If you don’t change your air filter regularly, air can’t pass through as readily. Clogged air filters are the number one cause of HVAC system failure.

The general rule of thumb for changing your air filter is every month or two. If you are unsure whether or not your air filter needs to be changed, take a look at the air ducts. Has dust and dirt built up on the registers? If so, it’s time for a change.

Variable speed blower fans are designed to eliminate the discomforts of on/off part-time heating and cooling. Typically, they are left running all year at a slow, steady pace to clean the air and even out the temperatures inside your home. They provide comfort and save energy. Because they are left running all year, they need steady service.

There are Different Types of Air Filters

Every air filter is different. Some air filters are washable. Some are electronic. The more efficient a filter is, the more fine dust is trapped during operation. The more fine dust trapped, the more often service is necessary.

Are you tired of changing your air filter every month or two? There is a better way. Consider installing a permanent filter that can be cleaned easily. Or you could try Filter Easy. They deliver your air filters when it’s time to change them.

Changing your air filter every month or two is important for the life of your HVAC unit, but air filters were not designed to improve air quality. If improving the air quality in your home is important to you, check out the Trane Clean Effects Air Filter. It traps more allergens and dust than regular filters, and it has a removable cartridge that can be washed and reused.

The Importance of Qualified HVAC Professional Services

The efficiency of an air filter is determined in an ideal situation:

  • in a laboratory,
  • on a perfect duct system,
  • using exactly sized particles,
  • moving at a known velocity.

To truly understand whether or not your HVAC system is working efficiently, consult your qualified Blue Frost Heating & Cooling HVAC professionals. We’ll determine whether or not the following is true of your home’s ductwork:

  1. Is it allowing for ideal particle speed?
  2. Are the bends approaching the filter smooth?
  3. Is the filter rack tightly sealed and properly sized?

Change your Air Filters

Changing your air filter is a simple task you can do yourself. An honest contractor doesn’t rejoice in the cheap thrills of charging his customers for a trip charge, just to change a dirty air filter. All of us at Blue Frost Heating & Cooling would rather help our customers whose air conditioners aren’t doing their job efficiently as opposed to helping someone whose air conditioner isn’t working because the air filter needs to be changed.
