A system that's short-cycling, tripping breakers, or throwing an error code isn't something to fix by trial and error. Testing comes before parts get ordered, on every Mckenna call.
The overwhelming majority of Hvac Repair visits come down to one of a handful of usual suspects: capacitors, contactors, control boards. 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.
Licensing, EPA certification, and insurance travel with every technician we send — no subcontractors ever.
Because we stage trucks close to Mckenna, most calls land a same-day or next-morning window instead of a week-long wait.
You approve a fixed price before we touch anything, and that price doesn't move once work begins, agreed to upfront.
Every truck carries manifold gauges, amp clamps, and combustion analyzers, 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.
Most no-start situations trace to a bad capacitor, 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.
What happens once you dial in.
Tell us what's happening and we'll get a tech moving — no phone tree to navigate.
You get a fully equipped truck, on time — not a vague all-day estimate.
We test, then quote, then wait for your go-ahead.
Same-visit completion in most cases, covered by our warranty.
Unedited feedback from our Mckenna customers.
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.
— N. Okafor, homeowner
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
What Mckenna customers ask most.
Same-day service is typical, next-morning as a fallback, and dispatch texts you once the tech is moving.
Yes, but it's a known number before anyone shows up, and it comes off the final bill if you go ahead with the repair, 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 Mckenna and the nearby zips listed here.
