Enid has plenty of HVAC trucks. It has less of this.
Garfield County is on my daily route from Kingfisher. I am not going to pretend I am the closest company to your house in Enid. What I bring is IGSHPA geothermal accreditation, a Master HVAC licence and 47 years, for the jobs where that is what the work actually needs.

The jobs worth calling Kingfisher for
Enid is the biggest town I serve and it is not short of HVAC companies. So rather than claim I beat all of them to your driveway, here is the honest version of when the drive up US-81 is worth it to you.
- Geothermal, start to finishI am IGSHPA accredited and a ClimateMaster GeoElite dealer. I design the loop, size the system and service it afterwards. Most shops subcontract the loop or decline the work.
- A second opinion you can checkHolding a quote for a compressor or a full replacement? I will look at the equipment and tell you whether the diagnosis holds up. That one is free.
- The Alfalfa Electric geothermal rebateIf Alfalfa Electric bills you, their geothermal rebate is $1,050 per ton with a ten ton cap. If you are on OG&E instead, their Oklahoma residential rebates are closed for 2026 and expected back in 2027. Tell me the name on your bill and I will confirm the live program before quoting.
- Water heatersGas and electric tank units, replacement and repair. A dedicated water heater diagnostic is $210, or $149 if I am already on site for something else. Tankless has no public price: I have to see it first.
If what you need is a capacitor on a Tuesday afternoon, an Enid company may well get there first, and I would rather say that than waste your afternoon.
What Garfield County does to equipment
Enid sits in open country north of the metro, and the two things that age equipment here are dust and wind-driven weather.
- Harvest dust in the condenserWheat harvest fills the air, and a condenser coil packed with chaff cannot shed heat. It is the single most common reason an Enid system loses capacity without failing outright. A proper coil clean fixes what people often try to fix with refrigerant.
- Filters loaded earlySame cause, indoors. A filter that would last three months elsewhere does not last three months here in July or in harvest season.
- Hail and storm damageBent fins, cracked line set insulation, and surge damage to control boards after lightning.
- Older systems on original ductEnid has a lot of mid-century housing where the duct was never resized when the equipment was upgraded. Static pressure explains more than another part swap will.
- Water heaters in unheated spacesGarages and utility rooms that get genuinely cold. Tank units in those spaces work harder and fail sooner than the label suggests.
- Geothermal on acreageLoop pressure, flow centre, desuperheater and controls, $348 flat whatever the hour.
What I come to Enid for
Geothermal
IGSHPA accredited, loop designed and sized by me, serviced by me afterwards. Free Saturday and Sunday consultation, and for geothermal I travel most of the state.

What happens when I get there
- The easy things firstThermostat, filter, breaker, outdoor disconnect. The equipment stays closed until those are ruled out.
- Electrical under loadCapacitor microfarads, contactor pitting and coil voltage, compressor amp draw.
- Refrigerant on calibrated gaugesSuperheat and subcooling against the maker’s spec. A leak gets found and repaired under EPA Section 608 rules.
- Airflow and coilsStatic pressure, blower speed and amps, coil condition at both ends.
- Written price, then you decideYou know the number before I touch a wrench.
What is safe to check, and what is not
Before I get there, there are a few things worth knowing, and they are the same whether you are in Enid or anywhere else I work.
- Gas smell, a CO alarm, smoke or arcingLeave the house. Call the gas utility or 911 from outside, then call me. I will not walk you through troubleshooting while you are standing in it, and that guidance is free and comes before any talk about a service call.
- Safe things to check yourselfThermostat mode and setpoint, the filter, whether a breaker has tripped, closed registers, anything visibly blocking the outdoor unit, and any fault code on the display. Write down what you see and what you hear.
- Stop and call insteadBreakers that keep tripping, water near the equipment, ice on the coil or lines, a burning smell, or a geothermal loop or flow alarm. Those are not wait-and-see.
- What I will not ask you to doOpen an energised panel, touch a capacitor, bypass a safety, add refrigerant or work on a gas valve. That is licensed work for a reason.
Who covers what, and for how long
Two different warranties get muddled constantly, so here is the plain version. My labor is mine: every repair carries a six month labor guarantee, and every system I install carries one year on parts and labor. If the same problem comes back inside that window, I come back and there is no charge for it.
The manufacturer warranty is separate and it belongs to them, not to me. A Trane system registered at install carries twelve years on the compressor and ten on parts through the TCS SELECT program. A Mitsubishi system installed by a Diamond Dealer in a single-family home and registered inside ninety days carries twelve years on parts and twelve on the compressor; without that registration it drops to five years on parts and seven on the compressor. Manufacturer coverage does not include labor, which is exactly why I register every system the day it goes in rather than leaving that to you.
Grain, wind and a lot of mid-century housing
Enid grew up on wheat and it still shows. The elevators on the skyline are among the largest grain storage capacities in the country, and harvest is a season you can feel in the air. That is not local colour to me, it is the reason so many service calls up here come down to a coil nobody has washed.
The housing runs heavily to mid-century stock plus the newer build-out on the edges, and Garfield County is served by a genuine mix: OG&E in town, and Alfalfa Electric, Central Rural, Kay Electric or Cimarron depending on where you sit outside it. Four different rebate situations inside one county, which is exactly why I ask who bills you before I talk about money. The measured ten year rate history for all of them is here, taken from the federal filings.
Straight answers
Is Hartzell’s actually local to Enid?
My shop is in Kingfisher and Garfield County is one of the seven counties I run every day, so Enid is regular work rather than a special trip. I am not going to claim I am the closest truck to your house. I am telling you what I am good at and letting you decide whether that is what your job needs.
Does harvest dust really damage an HVAC system?
It does not damage it so much as choke it. Chaff and dust pack into the condenser coil and the system loses the ability to reject heat, so it runs longer, works harder and costs more to run. People often read that as low refrigerant and add gas to a system that did not need it. A coil clean is $175 to $350 and usually the honest answer.
What rebates apply around Enid?
It depends entirely on who bills you. Alfalfa Electric’s geothermal rebate is $1,050 per ton with a ten ton cap. OG&E’s Oklahoma residential rebates are closed for 2026 and expected back in 2027. Central Rural, Kay and Cimarron each run their own programs. Tell me the name on your power bill and Shelby or I confirm the current program before any number goes in a quote.
Do you replace water heaters in Enid?
Yes, gas and electric tank units. If the truck rolls specifically for a water heater diagnostic it is $210, and $149 if I am already at the house for something else. Tankless has no published price because I have to see the install before I can be honest about it.
What does a service call cost in Enid?
$210 flat. That is $99 dispatch plus $111 diagnostic, and the diagnostic is not credited against the repair. After hours is $309. A geothermal diagnostic is $348 flat whatever the hour, and light commercial is $389 flat, day or night. The repair itself is quoted in writing before I start.
Do you offer tune-ups and maintenance plans in Enid?
Yes. A standalone tune-up is $229 on a weekday between 7am and 3pm. The plans are One Visit Spring or Fall 360 at $199 a year, Spring and Fall 360 at $360, and Full Year 360 at $499. The upper two carry ten percent off repairs, capped at $300 per repair.
Is there an extra charge for an emergency call in Enid?
After hours residential is $309, which is $198 dispatch plus the $111 diagnostic. It is not refundable and it is not credited against the repair. Geothermal does not change at night: it is $348 flat whatever the hour, and light commercial is $389 flat, day or night. Members on the Full Year 360 plan get the $198 emergency dispatch waived twice a plan year, though the $111 diagnostic still applies.
What brands do you work on?
All the major ones: Trane, Carrier, Lennox, Rheem, Goodman, American Standard, RunTru, Daikin, Mitsubishi and ClimateMaster, plus whatever the last owner left behind. I am a Trane TCS SELECT dealer, a Mitsubishi Diamond Dealer and a ClimateMaster GeoElite dealer, but brand does not limit the diagnosis and common parts ride on the truck.
Can I get a free consultation at the weekend?
For geothermal, yes. Free Saturday and Sunday evaluation, consultation and sizing, no charge and no obligation. For geothermal I travel most of Oklahoma as availability allows. Call 405-375-4822.
