Debunking a Common HVAC Misconception
One of the most persistent myths in the HVAC industry is that the most expensive, highest-MERV-rated air filters are always the best choice for your home. At Metro Heating & Cooling, we’re committed to providing honest, factual information to help you make informed decisions about your home comfort system.
Here’s the truth: Using an air filter with too high of a MERV rating can actually harm your HVAC system. Here’s why:
The Reality Behind Filter Ratings
• Higher-rated filters are denser and restrict airflow
• Restricted airflow makes your system work harder
• This can lead to increased energy costs
• May cause premature system wear and tear
Finding the Right Balance
Most residential HVAC systems are designed to work optimally with filters in the MERV 8-11 range. These filters provide excellent air quality protection while maintaining proper system airflow.
What You Should Do
1. Check your HVAC system’s manual for recommended filter ratings
2. Replace filters regularly (every 60-90 days)
3. Consider your specific needs (pets, allergies, etc.)
4. Consult with professionals for personalized recommendations
At Metro Heating & Cooling, we believe in providing solutions that actually work for your specific situation, not just selling you the most expensive option. Regular maintenance and proper filter selection are key to maintaining optimal indoor air quality and system efficiency.
Remember: The best filter is one that balances air purification with system performance, not necessarily the one with the highest price tag or MERV rating.
