Full Show 1/10/2026: AC's and Attic Ventilations

·1 hr 11 min·2 clips

If your bathroom mirror still has fog on it, you haven't run the exhaust fan long enough.

1. The Home Improvement Show on the Big 870, in its January 10, 2026 Saturday episode, covers attic ventilation, bathroom exhaust ducting, and air conditioning moisture control after a stormy night on the Gulf Coast. 2. Host Paul, a home-performance and moisture-focused contractor, takes texts and calls alongside co-host Courtney Fricke, who handles real estate questions, and producer Chris, who reads the texts aloud. 3. The episode's core theme is that moisture and air movement in Gulf South homes are best solved at the source, before upgrading equipment, and that winter through roughly end of April is the best window to work in attics. 4. Courtney's real estate tip defines "seller net" and lists debt payoffs, commissions, title company closing costs, prorated property taxes, and income tax consequences, warning that a judgment may carry interest and court costs beyond its $15,000 face value. 5. Paul tells a caller with a 65-year-old brick house that bath fan exhaust should go to a soffit, gable wall, or porch ceiling, with a roof jack with an insect screen as the second choice, and notes he often finds fans with "no damper" venting into the attic. 6. On underfloor insulation for a raised house, Paul specifies polyisocyanate board at R-13 (about 2.5 inches), checks wood with a pin moisture meter for 15 percent or less, and describes sealing a "six sided box" with caulk, compatible tape, and one-component foam. 7. Responding to caller Mike, Paul says the AC industry does a poor job addressing humidity, and that two-speed or variable-speed machines running at 60 to 70 percent capacity may not dehumidify well in low speed. 8. Paul prefers a single-speed high-efficiency unit paired with a properly designed duct system and a whole-house dehumidifier, which he says costs "quite a few thousand bucks" to install, needs maintenance every six months, and has a shorter life than the AC. 9. In his follow-up, Paul says any AC job should include a Manual J load calculation, then Manual D duct design and Manual S equipment selection, and that a company skipping them is "a big red flag." 10. Homeowners in humid climates, DIY renovators, and small-scale real estate buyers will get the most from this episode.
