Common HVAC Filter Myths That Cost You Money

The Truth About HVAC Filters That Every Homeowner Should Know

At All Climate Heating & Air Conditioning, we frequently encounter misconceptions about HVAC filters that can lead to unnecessary expenses and reduced system efficiency. Let’s clear the air about some persistent myths that might be affecting your home’s comfort and your wallet.

Myth #1: The More Expensive the Filter, the Better

Many homeowners believe that purchasing the most expensive filter with the highest MERV rating is always the best choice. However, professional maintenance experts know that using a filter that’s too restrictive can actually damage your system by reducing airflow and making your unit work harder than necessary.

Myth #2: Change Filters Every 90 Days, No Matter What

While this is a common recommendation, filter replacement frequency depends on several factors:
– Number of occupants in your home
– Presence of pets
– Local air quality
– Seasonal usage patterns
– Type of filter being used

Myth #3: Washable Filters Are More Cost-Effective

Washable filters might seem like a money-saving solution, but they often:
– Harbor moisture that can promote mold growth
– Provide less effective filtration
– Require careful maintenance to remain effective
– May not properly protect your HVAC system

The Bottom Line

Understanding these filter facts can help you maintain your HVAC system more effectively and save money in the long run. For residents in Redmond, Mountlake Terrace, Kirkland, Bellevue, Lynnwood, and Edmonds, proper filter maintenance is especially important due to our region’s varying seasonal conditions.

Remember that the best filter choice depends on your specific system and household needs. When in doubt, consult with a qualified HVAC professional who can recommend the right filter for your particular situation.
