How Data Centers Strain Your AC
2026/10/24
Give Use A Shout DAVE: I was reading trade news over coffee this morning, the kind of stuff most folks in Kingfisher never see, and there's a company called Vertiv buying up another company called King Environmental Services.

The Truth About Instant Hot Water
2026/10/21
Give Use A Shout DAVE: You ever stand in your shower waiting for the hot water to show up, tapping your foot, watching cold water run down the drain for two full minutes? I had a lady out on Highway 33 tell me she times it with her phone. Two minutes and forty seconds every single morning, just standing there cold. That's not a shower problem. That's a plumbing and hot water setup problem, and there's a piece of gear out there right now that fixes it. So today I want to talk about instant hot water, what it actu I'm Dave Hartzell at Hartzell's Heat & Air in Kingfisher, Oklahoma. 47 years in the trade, Master HVAC license.

How Wall Street Bought Your Air Conditioner

Give Use A Shout DAVE: You ever call a company you've used for ten years and the guy who shows up doesn't know your name, doesn't know your system, and quotes you a price that's double what your neighbor paid last month? That's happening more and more, and it's not because your old HVAC company got worse at their job. A lot of times it's because they got bought. Private equity firms are buying up heating and air companies all over this country right now, and I want to talk about what that means for you, sitting I'm Dave Hartzell at Hartzell's Heat & Air in Kingfisher, Oklahoma. 47 years in the trade, Master HVAC license.

Why Commercial HVAC Fails in Homes
2026/10/18
Give Use A Shout DAVE: Had a guy out by Dover call me last month. He'd been reading about these big commercial systems that heat your whole building and your hot water off one unit, and he wanted to know if he should rip out his water heater and tie everything together into one fancy setup. I told him, hang on, let's talk about what actually makes sense for a house in Kingfisher County versus what makes sense for a hotel in Oklahoma City. Big difference.

Why Your Air Purifier Fails to Fix Indoor Air Quality in Your HVAC System
2026/10/17
Give Use A Shout DAVE: I had a lady out on the west side of Kingfisher call me last spring. She'd already bought some kind of air purifier off the internet, plugged it into a wall outlet in her living room, and she was still sneezing every morning before she even got out of bed. She wanted to know why the box didn't fix it. And that right there is the conversation I want to have today, because a lot of folks think good air is something you buy in a box and set on a shelf.

Why AC Refrigerant Costs Are Skyrocketing
2026/10/16
Give Use A Shout DAVE: Had a lady out on Highway 33 call me last week because her AC guy told her a pound of refrigerant was going to run her almost two hundred bucks and he needed six pounds. She about fell over. And here's the thing, that's not him gouging her, that's just where refrigerant pricing has been heading for a couple years now. So when I saw two refrigerant companies in the news splitting up a business deal, I figured it was worth talking about, because it touches every single one of us with a unit I'm Dave Hartzell at Hartzell's Heat & Air in Kingfisher, Oklahoma. 47 years in the trade, Master HVAC license.

Why Geothermal Loops Outlast Heat Pumps

How Boilers and Radiant Heating Work
2026/10/10
Give Use A Shout CO-HOST: A homeowner in an older house in Enid calls in December. "My heat is working, but there is water on the basement floor, and this tank thing on the wall is making a ticking noise." No ductwork in the house at all. Cast iron radiators in every room. DAVE: That is a hot water boiler system, and that call tells me a few things right away. Let me walk through how these systems work, what is normal, and what you never mess with.
