Debunking a Common HVAC Myth

One of the most persistent myths in home heating and cooling is that the most expensive air filters are always the best choice for your HVAC system. At Comfort Care Services, Inc., we regularly encounter homeowners who believe that purchasing the highest-rated MERV-rated filters will automatically result in cleaner air and better system performance.

Here’s the truth: Using an air filter that’s too restrictive can actually harm your HVAC system and reduce its efficiency. Let’s break down why:

Why Higher MERV Isn’t Always Better:

1. Restricted Airflow
– Dense filters can make your system work harder
– Increased energy consumption
– Potential strain on motor components

2. System Design Limitations
– Most residential systems are designed for MERV 8-11 filters
– Higher-rated filters may not provide additional benefits
– Could lead to reduced system performance

What You Should Do Instead:

• Consult with a professional about the right filter rating for your specific system
• Change your filters regularly (every 1-3 months)
• Consider additional air purification methods if you need enhanced filtration

Remember, the best filter choice balances filtration with system efficiency. A properly sized and maintained mid-range filter will typically provide excellent air quality while protecting your HVAC investment.
