Hennessey, Kingfisher County

Twenty minutes up 81, and I make that run every week.

Hennessey is farm country: grain elevators off the highway, wheat running east into Garfield County, and a lot of houses built in the 1940s and 1950s that were never designed around ductwork.

What I find in Hennessey

The calls I actually run in Hennessey

  • Old farmhouses with no duct systemA 1940s house with plaster walls has nowhere to hide a duct run, which is why ductless units fit so well here.
  • Rooms the system never reachesAdditions and upstairs bedrooms on these places almost always run hot or cold.
  • Propane heat that costs more every winterOut this way propane is common, and a heat pump changes how the house is heated.
  • Equipment nobody has touched in yearsOn a working farm the HVAC is the last thing that gets attention, and it shows in the capacitor readings.
  • Dust and chaff in everythingHarvest dust packs filters and outdoor coils faster here than it does in town.
  • Water heaters and well systemsTank water heaters out here take a beating from hard water.

The visit

What happens when I get to your house

  1. The simple things firstThermostat, filter, breaker and the outdoor disconnect. I do not open the equipment until those are ruled out.
  2. Electrical under loadCapacitor microfarads, contactor condition and compressor amp draw. If the capacitor failed I check what killed it.
  3. Refrigerant on gaugesSuperheat and subcooling against the manufacturer’s spec. A leak gets found and repaired under EPA Section 608 rules, not topped off.
  4. Airflow and coilsStatic pressure, blower speed and amps, and the condition of both coils.
  5. A written price, then you decideYou get the number before I pick up a tool, and the diagnostic is not credited toward it.

What the drive actually means

How a Hennessey call works

  1. About twenty minutesStraight north on Highway 81 from my shop in Kingfisher, so a Hennessey call is a normal day, not a special trip.
  2. Same day is realisticBecause it is one road and no traffic, a morning call usually gets a same-day slot where the schedule allows.
  3. I carry the parts north with meThe truck is stocked before I leave Kingfisher, so the common repair happens on the first visit.

Pat Hennessey, and why the town sits where it does

The town is named for a freighter who never finished his trip. Pat Hennessey was hauling north through Indian Territory when he was killed on July 6, 1874, near the Kingfisher and Garfield county line. Bull Foot Park on the south end marks where the Chisholm Trail came through and where the drovers watered stock. Highway 81 still follows that same line north, and it is the road I take to get here.

Frequently asked

Straight answers, Hennessey

How fast can you get to Hennessey?

About twenty minutes from my Kingfisher shop, straight up Highway 81. Same day where the schedule allows, and no-heat calls in winter go first.

What does a service call cost in Hennessey?

$210 flat: $99 dispatch plus $111 diagnostic. After hours is $309, which is $198 dispatch plus the same $111. The diagnostic is not credited toward the repair.

My farmhouse has no ductwork. What are my options?

A ductless system. It mounts on the wall and needs a three inch hole instead of a duct chase, which is why it suits the older houses around Hennessey. I am a Mitsubishi Diamond Dealer, and a registered install carries 12 years on parts and compressor on a single-family home.

Is a heat pump better than propane out here?

It changes how the house is heated: one system does heating and cooling instead of burning propane for heat. Whether it fits depends on the house and the ductwork, and I will tell you straight after I look.

Do you answer at night in Hennessey?

Calls are answered 24 hours. After hours service is $309, non-refundable, and I quote the repair in writing before I start.

Do you service the farms and not just the town?

Yes. Everything around Hennessey is inside my seven county everyday area, and for geothermal I travel most of Oklahoma as availability allows.
