Odd cycling, a tripping breaker, or a blinking error code deserves an actual diagnosis, not a guess. We test capacitors, contactors, and refrigerant pressure before recommending a single part, on every Lohn call.
Most calls we get for Hvac Repair trace back to a short list of failure points — a weak capacitor, a pitted contactor, a control board acting erratically. We check all of them with a meter before quoting anything, which is the difference between a $150 fix and an unnecessary $1,500 one, and we'd rather find the $150 answer.
What you're actually getting when you call us.
Every tech carries a current license, EPA 608 refrigerant certification, and liability coverage — no subcontractors ever.
Trucks are staged around Lohn, TX for quick Lohn response, most calls land a same-day or next-morning window instead of a week-long wait.
The number we quote is the number on the invoice, agreed to upfront.
Manifold gauges, clamp meters, and combustion analyzers ride on every truck, so the fault gets measured, not assumed.
The repairs behind most of our service calls.
The first move is isolating exactly which of these failed: capacitor, contactor, thermostat call, or charge level.
A failed run capacitor is behind a huge share of no-start calls, and it's confirmed with a microfarad reading, not a guess, and we confirm it with an actual meter reading before replacing anything.
High amp draw or a seized bearing on the blower motor shows up as weak airflow or a burning smell, and we test the windings before recommending replacement.
A miscalibrated thermostat or a glitchy control board can mimic a much bigger failure than it actually is, and we rule these out before quoting anything larger.
We locate the real leak, because a top-off without finding the source only buys a few weeks.
Heating-side components get tested individually, since a dirty flame sensor is a five-minute fix, not a new furnace.
Four steps, start to finish.
Describe the symptom and we route the nearest available tech — no phone tree to navigate.
A stocked truck arrives within your confirmed window — not a vague all-day estimate.
We test, then quote, then wait for your go-ahead.
Most repairs wrap same visit, backed by a written labor warranty, covered by our warranty.
Straight from completed service calls.
Breaker kept popping every time the blower kicked on. Turned out to be a shorted wire nobody had caught in two prior visits from other companies.

Appreciated getting a text with a two-hour window instead of the usual 'sometime this afternoon.' Tech was right on time.
— V. Delgado, property manager
System was cycling on and off every few minutes. They traced it to a thermostat wiring issue, not the compressor everyone assumed it was.
— L. Whitfield, homeowner
Third HVAC company we've tried for our small office building. First one to actually pull a service history instead of starting from zero each visit.
— C. Abernathy, office manager
Common questions before booking.
Same-day service is typical, next-morning as a fallback, and dispatch texts you once the tech is moving.
There's a set diagnostic charge, disclosed when you book, and it's subtracted once you approve the fix.
We diagnose first and explain the actual cause before quoting — no billing for guesswork, so you're never charged for an assumption.
No — the flat-rate quote holds unless new work is discovered and you approve it separately unless something new turns up and you sign off on it.
Gas and electric equipment are both covered equally.
We service whatever's already installed, regardless of who put it in.
Coverage extends through Lohn and the nearby zips listed here.
