    Refrigerant top-offs are an expensive myth

    Give Use A Shout HOST A: Dave, a homeowner called you yesterday because their AC ran fine in May and now the house won't get below 78 in the afternoon. What was your first question? HOST B: How long since the last refrigerant top off. They said two summers ago, paid 380 dollars to add freon. That tells me everything I need to know before I even drive out there. They have a leak. They have had a leak for at least two years. And whatever tech topped them off in 2024 did them no favors.

    Why adjusting your thermostat costs money

    Pick the right water heater for home

    Give Use A Shout HOST A: I want to walk into this one with the conversation that happens on probably forty percent of service calls. Homeowner's water heater is leaking, or it is twelve years old and on borrowed time, and they ask me, what should I replace it with. They have read a couple of articles online. They have heard tankless is the new thing. They have heard heat pump water heaters are super efficient. They are confused. HOST B: And the right answer is, it depends.

    Why Experts Refuse Summer AC Tune-Ups

    Give Use A Shout HOST A: It is June 18 in Kingfisher. 96 degrees outside. A homeowner calls Hartzell's wanting to book the $229 tune-up they saw advertised in the spring. Dave tells them no, book it for October or wait until March next year. The homeowner is irritated. They are willing to pay. Why is Dave turning down work? HOST B: Because what they are asking me to do, I cannot do correctly in June heat. And if I cannot do it correctly, I am not going to charge them $229 for it. It is that simple.

    Halve Your Power Bill with Geothermal

    Give Use A Shout HOST A: It is the first week of July in Kingfisher. The temperature has been over 100 degrees for 8 days straight. A homeowner in a 2200 square foot ranch on a slab opens their OG&E bill. 340 dollars. Their neighbor across the street, same builder, same square footage, same year built, opens their bill. 165 dollars. Same weather. Same house. Same family of four. The difference is the system in the back yard. HOST B: The 165 dollar bill is the geothermal house.

    Your outdated thermostat habits spike your bill

    Give Use A Shout The number on your thermostat screen is probably wrong. Not broken wrong. Strategy wrong. The Department of Energy quietly rewrote its thermostat guidance and the old set it and forget it rule no longer matches how modern variable speed equipment runs. In this episode I walk through the new DOE setpoint advice, why the old 8 degree setback rule hurts efficiency on a two-stage or variable speed system, and what I actually recommend to homeowners in Kingfisher running everything from 1990s single-stage units to modern inverter heat pumps.

    Which water heater actually fits your home

    Give Use A Shout About forty percent of my service calls end with a water heater question. The unit is leaking or it is twelve years old, and the homeowner asks what they should replace it with. They have read a couple articles. They have heard tankless is the new thing. They have heard heat pump water heaters are super efficient. They are confused. In this episode I break down the three legitimate options in 2026, when each one fits, and the install details most Oklahoma homeowners do not hear from a salesman trying to sell them the wrong one.
