Why folks in Loyal call me
I run my routes out of Kingfisher, and Loyal is a regular stop. Most of my Loyal customers found me by referral. I keep my truck stocked with the parts that fail most often in Oklahoma weather, so when I roll up I usually have what I need to fix the system the same day.
I quote everything in writing before the work starts. No “you need this” pressure, no equipment swaps you did not ask for. Just diagnosis, fix, written invoice. Call 405-375-4822 or book online at hartzellsheatair.com.
Common questions from Loyal (73756)
How much does an AC repair cost in Loyal?
A residential service call is $210 flat: $99 dispatch plus $111 diagnostic. The $111 diagnostic is not credited toward the repair. If I leave a written repair estimate and you accept it within 10 days, I give the $99 dispatch fee back. Most Loyal repairs land between $200 and $850 all-in. Refrigerant work, blower motor failures, and capacitor swaps are the most common categories I see in this ZIP.
Do you offer same-day service in Loyal?
Most days yes. If you call before noon and the job is straightforward (no-cool, no-heat, leak), I can usually be at your house in Loyal that same afternoon. Heavy install days or extreme-weather backlog can push it to next-day, but I always tell you up front when you call.
What does a new HVAC install in Loyal run?
A complete 3-ton air-source heat pump installed (heat pump + air handler + thermostat + permits) runs about $10,000 to $14,000 in Loyal, depending on equipment tier and ductwork condition. OG&E rebates up to $3,000 stack on top. Geothermal is a different conversation, that is $25,000 to $36,000 range before rebates. I write a free estimate either way.
Do you service all brands in Loyal?
Yes. Master HVAC license, NATE certified, 47 years on tools. I install Trane, Mitsubishi, Amana, ClimateMaster (geo), RunTru. I service whatever brand is sitting on your slab. If it has a refrigerant cycle and ductwork, I can work on it.
