Are Fiberglass Air Filters Bad? Fiberglass vs Pleated—Which Protects Your HVAC?

Homeowner comparing a thin fiberglass air filter with a pleated HVAC filter beside a residential furnace to determine which better protects the HVAC system.

A fiberglass filter can look perfectly clean and the system behind it can still be in trouble. That is the part I explain most often, standing at an air handler while a homeowner tells me their tech said a three-dollar panel was all they needed. He was not wrong. He answered a narrower question. A … Read more

By entering details about their current insulation and desired R-value, users can visualize the financial benefits, represented by money bags, piggy banks, and charts, and determine the ideal insulation solution to improve their home's comfort and value.

We’ve pulled off more than a few attic hatches across Florida and found insulation so thin and compressed it was barely doing a thing. The homeowner had no idea. They just knew their power bills kept climbing and their AC never quite caught up. The U.S. Department of Energy puts a number on it: a … Read more

What I found inside: coils caked with two seasons of grime, a condensate drain that hadn’t cleared in … Read more

A 5-step infographic illustrating How Dust Moves Through Your Home: Understanding Indoor Airflow, from dust sources and HVAC circulation to final settling zones.

After years of inspecting HVAC systems in Florida homes, I can tell you this: dust is never just sitting still.

Last July, I pulled a MERV 8 filter from a home near the I-75 and Dearborn interchange. It had been in the system for 38 days. It looked like 90. The homeowner had no idea Detroit’s AQI had been running above 130 for most of that stretch, and by the time we talked, she had … Read more
