From field experience, a failed ignitor generates more unnecessary service calls than any other single furnace problem. The part itself runs $20 to $80. Most homeowners who’ve confirmed the diagnosis complete the repair in under 30 minutes. When a furnace runs through its startup cycle without producing heat, the ignitor is almost always where to … Read more
Aurora’s air quality can swing from Good to Unhealthy in under 12 hours during wildfire season—and that shift reaches your HVAC filter before most residents feel it in their lungs. I’ve tracked this pattern across Front Range homes for years. What the AQI reads outside shapes what your air filter does inside, and most Aurora … Read more
The filter you slide into a brand new AC unit on day one affects more than air quality. It affects whether your manufacturer honors the warranty when something goes wrong in year one. We’ve watched homeowners install the wrong MERV rating on a $6,000 system and get a denied warranty claim three months later, all … Read more
A homeowner called me last July. Her kids had spent the afternoon outside in Milwaukee while the AQI sat at 158. She found out that evening when her daughter came inside with burning eyes and a headache. The alert had been active since noon. No one had told her. She hadn’t thought to check. That’s … Read more
I’ve walked into a lot of homes where the homeowner swears they change their filter regularly — and yet dust is still settling on every surface within days. Nine times out of ten, the culprit isn’t the cleaning routine. It’s the filter setup. Homes dealing with persistent dust, mild allergy triggers, or uneven airflow through … Read more
A new HVAC unit runs $5,000 to $12,500 installed. Most cost guides stop there. We don’t. From what I’ve seen in the field, the gap between a good investment and an expensive mistake comes down to one thing: knowing what’s actually driving the quote before you agree to it. This page gives you the field-tested … Read more
An 8x16x2 air filter’s actual dimensions are approximately 7.5″ x 15.5″ x 1.75″—about a half-inch smaller per side than the labeled size. This intentional undersizing allows the filter to slide smoothly into your system’s frame without forcing or jamming. I’ve pulled hundreds of filters out of systems over the years, and the size confusion with … Read more
A MERV 13 filter won’t kill your CFM — but the wrong one will. I’ve seen homeowners upgrade to MERV 13 for better air quality, only to end up with frozen coils and a blower motor working twice as hard. The filter wasn’t the problem. The mismatch was. From what I’ve seen in the field, … Read more
That lingering cough, the stuffy nose that won’t quit, the dust that reappears hours after cleaning. Your air ducts could be behind all of it. The EPA reports that indoor air can be two to five times more polluted than outdoor air, and your ductwork plays a direct role in what your family breathes every … Read more
Choosing between a MERV 13 and a HEPA filter for your 23.5×23.5×2 slot? Here’s the short answer: MERV 13 works with your existing HVAC system right out of the box, while HEPA filters trap finer particles but can starve your blower motor of airflow without costly modifications. That’s not textbook theory. We’ve pulled both filter … Read more
