    Toxic mercury in old thermostats

    Give Use A Shout DAVE: If you've got an old round Honeywell thermostat on your wall, the kind with the little mercury switch inside, you're sitting on a small environmental hazard. I pulled one off a wall in Okarche last week, and when I tilted it, you could see that silver bead of mercury rolling around in the glass tube. That's toxic stuff. Most people have no idea they're there, and even fewer know what to do with them when we swap them out. Today I want to talk about why these things matter, where they go wh I'm Dave Hartzell at Hartzell's Heat & Air in Kingfisher, Oklahoma. 45 years in the trade, Master HVAC license.

    Why Your New AC Is Mildly Flammable

    Give Use A Shout DAVE: If you walked into a grocery store in Kingfisher last week and noticed the coolers look a little different, or you're a business owner wondering why your walk-in cooler guy is suddenly talking about new refrigerants, you're not imagining things. The whole refrigeration industry just went through the biggest change in 30 years, and it's not just affecting restaurants and grocery stores. The same refrigerants going into commercial coolers are coming to your home air conditioner, and most fol I'm Dave Hartzell at Hartzell's Heat & Air in Kingfisher, Oklahoma. 45 years in the trade, Master HVAC license.

    Why $49 AC Tune-ups Are Bait

    Give Use A Shout HOST A: Trane published a piece on their consumer blog that quietly puts numbers on something the trade has been arguing about for years. National range for a residential AC tune-up. $120 on the low end. $350 on the high end. HOST B: That is a wide range.

    Your CO Alarm Ignores Slow Leaks

    Give Use A Shout HOST A: Here is something that should bother every gas-furnace owner in Oklahoma. The carbon monoxide detector in your hallway, the one you bought at the hardware store for 25 bucks, is built by federal regulation to ignore the kind of CO leak that will quietly poison your family over the course of a winter. HOST B: That is a sentence I want you to back up. Because I think most people assume their CO detector is the safety net.

    The Five Rung HVAC Career Ladder

    Give Use A Shout DAVE: I started in this trade at 18, pulling sheet metal in 105 degree attics for $4.50 an hour. Forty-five years later I sign my own paycheck in Kingfisher, Oklahoma, and there are five distinct rungs between where I started and where I am now. Most homeowners do not know which rung the guy walking up their driveway is on, and that is exactly what decides whether their AC runs another ten years or fails again next summer.

    Budget mini splits versus Mitsubishi Hyperheat

    Give Use A Shout HOST A: Dave, you got a call last February. Homeowner in Yukon installed an ACiQ mini-split in his detached garage workshop the previous summer. The unit worked great. Then a 6 degree morning hit and the heat pump went into defrost mode and never came out. The garage was 38 degrees by the time he called you.
