Around Derby
Repairs, seasonal maintenance, and replacement work on homes and rental properties, mostly along K-15 and Rock Road.
Running but not cooling, frozen lines, water in the pan, or a condenser packed with cottonwood and grass clippings. We measure pressures and airflow instead of guessing at a part.
No heat, short cycling, or a furnace that lights and quits. Every heating call includes a heat exchanger inspection — it is the one failure you cannot smell your way out of.
Spring cooling prep and fall heating prep, with every reading written down: filter size, static pressure, refrigerant charge, temperature rise.
Permits in Derby
Derby permits its own residential work through the City of Derby, separate from MABCD. Any replacement or duct change is confirmed with the city before we quote it.
Kansas has no statewide HVAC license. Licensing and permits are handled city by city, and Derby does not follow Wichita's rules. That matters mainly for full replacements and new ductwork, which typically need a permit and an inspection.
Service, diagnostics, and maintenance generally do not. If your job needs a permit, we tell you before any work starts rather than discovering it halfway through.
Common calls
Usually refrigerant charge, restricted airflow, or a dirty outdoor coil. Sometimes it is a filter nobody has changed since last summer.
A backed-up condensate drain is the most common cause of rental water damage we see. Shut the system down and call — running it compounds the damage.
Turn it off at the thermostat. A frozen system that keeps running is how a two-hundred-dollar repair turns into a compressor replacement.
On and off every few minutes. Often an oversized system, a failing sensor, or a control board — worth diagnosing before it wears the compressor out.
