  • Why Your Air Purifier Fails to Fix Indoor Air Quality in Your HVAC System

    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. It ain't. It's a system. Let's get into

  • Why AC Refrigerant Costs Are Skyrocketing

    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

  • Why Air Conditioners Freeze in Summer

    Give Use A Shout

    DAVE: Had a call last week out on Route 33 toward Okarche. Family's got a system that's running nonstop, house sitting at 78 when the thermostat's set to 72, and the outside unit is ice cold to the touch in the middle of August. That's not a system working hard, that's a system in trouble. And nine times out of ten when I hear that story, it comes down to four letters I want to walk you through today. A, B, C, and D. Sounds simple. It is simple, once somebody explains it the right way.

  • Why Emergency Heat Spikes Your Electric Bill

    Give Use A Shout

    CO-HOST: A homeowner in Yukon calls in February. "My electric bill is way up this month and the house feels fine." I ask one question. "What is your thermostat set to?" And they say, "Emergency heat. It was cold, so I figured that was the cold weather setting."

    DAVE: That is the most common emergency heat mistake there is. It is not a cold weather setting. It is a backup setting. Let me explain the difference.

  • Why Geothermal Loops Outlast Heat Pumps

    Give Use A Shout

    CO-HOST: It is January, 12 degrees, wind out of the north. A neighbor's outdoor unit is covered in frost and the heat strips are running. Next door, a geothermal house is quiet. There is no outdoor unit at all.

    DAVE: Because the heat in that house is coming from the ground, not the air. And the piece of pipe in the ground doing that work may have been put in before the homeowner's kids were born. I want to talk about why.

    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.

    HOST A: It is the first cold morning of the year in Kingfisher. Thirty eight degrees outside. You walk to the thermostat, you turn it up, and nothing happens. Or the fan blows, but the air coming out of the vents is cold.

    HOST B: And that is my busiest morning of the fall. Every year, the first cold front comes through and I get a stack of calls before breakfast. Some of those I can fix over the phone in two minutes. Some of them, I tell the homeowner to step outside and call the gas company. T

But nine times out of ten in central Oklahoma, that smell is moisture somewhere it shouldn't be, and your AC system is either the reason it's there or the reason it's not getting fixed.
