How To Change Your HVAC Filter

How To Change Your HVAC Filter

An HVAC unit filters out the air it cools to ensure no particles of dust or dirt enter the air you breathe. This can be very detrimental for your health as inhaling particulates and microorganisms could compromise your immune system and damage your lungs. If you notice particulates floating through the air when the sun shines through a window, it’s time to replace your HVAC filter. Read on to learn when and how you should replace your air filter.

WHEN TO REPLACE YOUR FILTER

As a general rule of thumb, your air filter should be replaced every 1 to 3 months, however this depends on a variety of factors. Here’s a list of variables that might affect how frequent you should change your filter.

  • Cleanliness of your home. If your home has a lot of dust, pet hair, or if you smoke, you should replace your filter more frequently
  • Number of people in your home determines how often your filter must be replaced.
  • Filter type determines frequency of replacement. Some filters can only be used for short periods, while others are designed for long-term usage.
  • If you’ve used your furnace regularly for at least 2 months
  • You notice allergies and congestion

If you notice any of these factors above, it’s time to replace the filter on your HVAC system.

HOW TO REPLACE YOUR AIR FILTER

Replacing your HVAC is a relatively simple process that can be mastered with practice. Remember, if you’re having difficulty and are unable to replace the filter yourself, be sure to contact Renown Air Conditioning and experience service from the finest HVAC contractor in Deltona. Here are the 4 steps for replacing your air filter.

1.    LOCATE THE FILTER

First, locate your air filter. They’re typically located in a slot near the intake unit of your HVAC system. Other possible locations are the return air duct on the bottom of the unit, air intake on top of the unit, or several small air grills throughout your home. Once you locate it, identify the brand, model, and specific dimensions. This will come into play in the next step.

2.    BUY A REPLACEMENT FILTER

After examining the specific type and dimensions of your air filter, find a replacement. It’s very important to be as specific as possible when buying a replacement filter. If the replacement you buy isn’t compatible with your HVAC system, it could cause damage or be inoperable.

The most inexpensive type of filter is a fiberglass model. They typically come in blue and are commonly used for homes and apartments. Fiberglass filters are effective if there isn’t much air pollution in your house. If you have pets and many residents in your home, invest in a polyester or pleated filter. They’re more expensive but significantly more effective that their fiberglass counterparts.

3.    OPEN THE STORAGE COMPARTMENT

Once you have the correct replacement filter, carefully open the storage compartment and take the old filter out if you haven’t yet. Clear the area of dust and debris before placing the new filter.

4.    REPLACE THE FILTER

Carefully place the new filter in the compartment. Make sure that it’s secure and check for damage to the filter and the compartment before securing it. Once it’s in place, the job is done.
