The Truth About Furnace Filters Every Homeowner Should Know
One of the most persistent myths in home heating maintenance revolves around furnace filters, and we at Irish Air want to set the record straight. As your trusted HVAC professionals serving Franklin, Greenwood, and Southport, we’ve heard countless misconceptions that could be costing you money and efficiency.
The Biggest Filter Myth Debunked
Perhaps the most damaging myth is that “the more expensive the filter, the better it is for your system.” This simply isn’t true. In fact, using a filter that’s too dense can actually restrict airflow and force your furnace to work harder, potentially leading to premature system failure.
Here’s what you really need to know:
• Basic fiberglass filters are often sufficient for most residential systems
• MERV ratings between 8-11 are typically ideal for home use
• Changing filters regularly is more important than buying premium ones
• High-efficiency filters aren’t necessary unless you have specific health concerns
The Real Cost of Following This Myth
When homeowners install ultra-high MERV rated filters thinking they’re doing their system a favor, they might experience:
1. Increased energy bills
2. Reduced heating efficiency
3. Unnecessary strain on the blower motor
4. Potential system overheating
Instead of focusing solely on filter quality, we recommend establishing a regular maintenance schedule that includes proper filter changes and professional inspections.
Remember, the best filter choice depends on your specific system specifications and household needs. If you’re unsure about what filter to use, our experienced technicians can help you make the right choice for your home’s heating system.
Don’t let myths drive up your heating costs. Trust the facts and keep your system running efficiently all winter long.
