Cooling

Cooling that holds up to a Kansas August

Summer here does not ease in. It arrives in June and sits on the Flint Hills until September, and a system that limped through May will fail on the first weekend above 100 °F — which is also the weekend every contractor in the county is booked solid.

That timing problem is the whole argument for servicing cooling equipment in spring. It is also why we keep common failure parts — run capacitors, contactors, condensate pumps, blower motors — stocked on the trucks rather than ordering them when somebody is already sweating.

We work on every residential cooling configuration found in this area: split systems with a gas furnace air handler, all-electric heat pumps with strip backup, dual-fuel setups, and ductless mini-splits in additions and garages.

What is included

Air Conditioning: the full scope

Four areas of work under this heading. Most calls fall into one; larger projects touch several.

Air conditioning repair

Diagnostics start with measurements, not guesses: supply and return temperatures, static pressure, amp draw on the compressor and fan, superheat and subcooling. Most single-component faults are fixed on the first visit.

  • Capacitor, contactor and relay failures
  • Compressor and condenser fan motors
  • Refrigerant leak detection and repair
  • Frozen evaporator coil diagnosis
  • Condensate pump and drain line clearing
  • Control board and thermostat faults

Installation and replacement

New equipment starts with a room-by-room Manual J load calculation. Sizing from the old unit's badge is how a house ends up with a system that short-cycles for twenty years and never removes humidity properly.

  • Room-by-room load calculation
  • Duct static pressure survey before quoting
  • Line set evaluation or replacement
  • Proper evacuation to 500 microns
  • Charge verified by weight and subcooling
  • Airflow set and documented at handover

Precision tune-ups

A real tune-up is a twelve-point service with written measurements, not a rinse of the condenser and a sticker on the cabinet. It is included twice a year on the Yearly Service Agreement.

  • Coil cleaning, indoor and outdoor
  • Electrical connections torqued and inspected
  • Capacitor microfarad reading against rating
  • Refrigerant state verified
  • Blower wheel inspection and cleaning
  • Condensate safety switch tested

Ductless mini-splits

For additions, converted garages, sunrooms and older houses without ductwork, a ductless head gives zoned cooling and heating without tearing into the structure.

  • Single and multi-zone systems
  • Heating down to low outdoor temperatures
  • Quiet operation for bedrooms and offices
  • Individual room control
  • Minimal structural intervention
  • High seasonal efficiency
Know the symptoms

Six signs your air conditioning needs attention

Recognising these early is usually the difference between a service call and a replacement.

Warm air from the supply registers

Usually a refrigerant charge problem, a failed compressor or a stuck outdoor unit. Switch the system off rather than letting it run — a compressor short on refrigerant is a compressor destroying itself.

The outdoor unit hums but the fan does not spin

Classic failed run capacitor. It is an inexpensive part, but running the compressor against a dead capacitor for long is not inexpensive at all.

Ice on the refrigerant line or the indoor coil

Airflow starvation or a low charge. Turn the system off, set the fan to ON to thaw the coil, and change the filter while you wait.

The system runs constantly and never satisfies

Undersized equipment, a dirty coil, leaking ducts or a charge issue. On a design day some run time is normal; on a mild evening it is not.

Water around the indoor unit

A blocked condensate drain or a failed pump. Cheap to fix now, expensive once it has soaked a ceiling or the floor of a finished basement.

A bill that climbs with no change in habits

Efficiency loss is gradual and easy to miss. Comparing this July to last July on the same meter is the cleanest signal you will get.

Questions

About air conditioning

Once a year, in spring, before the first sustained hot spell. Systems that also provide heating — heat pumps — benefit from twice-yearly service because they run all year. A skipped year is rarely catastrophic; five skipped years usually shows up as a compressor.

The only defensible answer comes from a Manual J load calculation: square footage, orientation, window area and type, insulation levels, infiltration and duct losses. Oversized equipment is a common and expensive mistake — it cools the air quickly, shuts off before it has removed moisture, and leaves the house cold and clammy.

Not immediately, but plan for it. R-22 has not been produced or imported since 2020, and reclaimed stock is expensive and getting worse. If an R-22 system needs a significant repair, the arithmetic usually favours replacement.

Much more so than it was fifteen years ago. Modern cold-climate heat pumps hold useful capacity well below freezing, and pairing one with a gas furnace as a dual-fuel system lets the controls pick whichever fuel is cheaper at a given outdoor temperature. We will run the numbers for your actual utility rates.

Yes. We service all major residential brands regardless of who installed them. Equipment still inside its manufacturer warranty may need parts sourced through that brand's distributor, which occasionally adds a day.

Customer feedback

What people say about this work

“Our AC quit on the hottest Saturday of the year. Henton had somebody at the house within two hours, found a failed run capacitor and had us cold again before dinner. No drama, no upsell.”

Dana R.Manhattan, KS

“They replaced a 24-year-old furnace and added a return duct we badly needed. The crew laid down drop cloths in every room they walked through and hauled the old unit away the same afternoon.”

Mark & Julie T.Wamego, KS

“Main line backed up into the basement on a Sunday. The technician cabled it, then ran a camera and showed me the root intrusion on screen so I could actually see what I was paying to fix.”

Priya S.Manhattan, KS

“I have used Henton for both of my rental properties for six years. They quote a range up front, call when they are running late, and the invoice always matches what we discussed.”

Greg H.St. George, KS

“The yearly service agreement is the best money I spend on this house. Two visits a year, and they caught a cracked heat exchanger before it became a carbon monoxide problem.”

Ellen W.Manhattan, KS

“Tankless install in a 1940s house with tight venting. They took the time to do it right instead of talking me into something easier for them. Hot water has been flawless for two years.”

Tomas L.Riley, KS
