Common Heating Myths Explained
One of the most persistent myths in home heating maintenance is that the more expensive your furnace filter is, the better it will protect your HVAC system. At Ware’s Heating & Cooling, we regularly encounter homeowners who’ve been spending unnecessarily on premium-priced filters when they don’t need to.
Here’s why this myth needs debunking:
Understanding Filter Ratings
• MERV ratings (Minimum Efficiency Reporting Value) indicate filtration effectiveness
• Most residential furnaces work best with MERV 8-11 filters
• Higher-rated filters can actually restrict airflow
The Real Cost of Premium Filters
Using expensive, high-MERV filters in a standard residential system can:
• Reduce system efficiency
• Increase energy costs
• Potentially damage your furnace
• Force your system to work harder
What You Really Need
For most homes in Lexington, Georgetown, and Midway, KY, a standard pleated filter with a MERV rating between 8-11 provides:
• Adequate dust filtration
• Proper airflow maintenance
• Cost-effective protection
• Optimal system performance
Remember, the key isn’t buying the most expensive filter – it’s choosing the right filter for your specific system and maintaining a regular replacement schedule. If you’re unsure about which filter type best suits your furnace, Ware’s Heating & Cooling can help you make the right choice for your home’s needs.
Always consult with heating professionals before making significant changes to your filtration system, as every home’s requirements are different.
