Why Is Changing AC Filters Regularly So Important?

Many people forego filter replacements because they deem it an optional aspect of AC upkeep, but that’s far from the truth! It brings many worthwhile advantages like:


  • Improved cooling: An operational filtration system will keep debris from clogging the system and help circulate air more efficiently. This means consistent temperature control and a more comfortable home or office environment.
  • A healthier space: Fresh AC filters promote cleaner indoor air by efficiently trapping pollutants and allergens. Your family or staff will breathe easier and become less prone to respiratory issues and allergic reactions.
  • Enhanced system longevity: There’s a reason why AC manufacturers recommend regular filter changes. It significantly reduces the strain on your HVAC system and prevents overheating.

Signs You Need to Up Your AC Filter Replacement Frequency

If you already follow a regular maintenance schedule and still notice these red flags, it’s time to tweak your approach:


  • Increased usage costs: Have you noticed your energy bills creeping up without a change in usage habits? A dirty filter could make your system work harder to produce the same level of cooling.
  • Unusual noises: Clogs will restrict airflow, which causes your unit to strain and produce odd sounds. Most people hear a faint banging or whistling.
  • Dirty surroundings: Do you keep finding more dust around your home than in a Wild West movie set? If you regularly clean your interiors but still have this issue, check your filters.
  • Filthy vents: Check your AC vents and registers for a layer of grime or pet hair. Another symptom of clogged filters is poor airflow, so place a hand near a register and feel for a steady breeze.
  • Allergy symptoms: Your property’s inhabitants sneezing or coughing more often should ring alarm bells. A quick filter change can often mitigate these symptoms and make your space more comfortable for everyone.


How to Replace Your Filters Properly in Bozeman

Changing your AC filter is a breeze, and getting it done right can majorly amp up your comfort and health at home. Here’s a quick run-down to ensure you nail the process every time.


Read the Manual

Start by taking a gander at your AC unit’s user instructions. It’s your go-to resource for specifics on the filter type your system needs and where to find its compartment. 


If you can’t find the handbook, don’t worry. Most AC manufacturers have online materials available, or you can call your Bozeman HVAC specialist for advice.


Purchase the Right Replacement

Double-check the required size and material before making a purchase. Some products might have higher MERV ratings (a measure of a filter’s ability to catch particles,) but they may not suit your specific system. The last thing you want is to diminish your unit’s efficiency or cause damage.


Install

Always turn off your system first. Locate the filter compartment, which is usually inside the return duct or air handler. Slide out the old one and note the airflow direction marked on its frame. Match this direction when you slide in the new filter. 


Seal the compartment back up, flip the AC on, and take a deep breath of that fresh, crisp air.
