Walk into a typical 1980s elementary school in late August, and you’ll find a maintenance lead pulling 20×25 filters out of a rooftop unit, holding one up to the light, and frowning. The cardboard says MERV 8. The system was sized for MERV 8. The CDC, ASHRAE, and most school nurses now want MERV 13. … Read more
When a homeowner calls us about chronic allergy flare-ups and we pull the air filter, the media usually tells the story before anyone finishes talking.

On our service calls, we see this regularly — systems that have been quietly underperforming for years while homeowners absorb the cost without knowing why.

A Lexington homeowner sent us a photo last August. She had pulled her HVAC filter three weeks after putting in a fresh one. It was already gray. Nothing about her home routine had changed. What had changed was the air outside. At ACTuneupPros.com, we hear versions of that story more often than you would expect. … Read more
Why I Put Together This Comparison In my work covering HVAC maintenance and filter decisions at ACTuneupPros.com, I hear the same question from homeowners almost every week: pleated or fiberglass?
