No hourly billing games. No mystery invoices. Just a licensed Wittmann technician who tests the system, tells you what's actually wrong, and quotes one number — that's the whole pitch.
The short version of who shows up at your door.
We do one thing in Wittmann: HVAC repair and installation, done right the first time. Licensing, background checks, and EPA certification aren't optional for anyone we send out — there's no gray area on that.
We got tired of hearing the same complaint from new Wittmann customers: the last company quoted one price on the phone and a different one at the door. So our pricing is flat and written down before a wrench touches anything, full stop, and that's true whether it's a $150 capacitor or a full system.
Referrals are how we grow here, so cutting corners isn't worth the reputation hit. We say the cheap fix out loud, even when it costs us the bigger sale.

What we tell Wittmann homeowners to watch for.
Refrigerant leak, failing compressor, dirty coil — all different fixes, all confirmed with a gauge before we quote anything.
A specific noise usually means a specific part — bearing, belt, motor mount — not a system that needs replacing.
The system works harder long before it fails outright.
Either pattern wears down components ahead of schedule.
Standing water usually means a blocked drain line, worth catching early.
Ductwork is the usual suspect here, not the unit.
A musty odor on startup points to moisture somewhere in the system.
Aging equipment tends to fail at the worst time — a proactive look can flag whether replacement planning makes sense.
Certain smells mean stop running the system and call, not wait and see.
Ice on the condenser in cooling season points to airflow or charge problems, not something to just wait out.
Humidity and temperature are two different problems.
From a 2am emergency to a full replacement.
Total no-heat or no-cool gets same-day dispatch, day or night — a real person answers the line, not a voicemail loop, answered by an actual dispatcher, any hour.
The approach doesn't change based on the size of the job — test first, quote second, always.
Downtime costs businesses money, so commercial accounts get moved to the front of the line.
Beyond heating and cooling, we handle the air quality side too — purification, humidity, filtration.
A twice-yearly tune-up catches a failing capacitor or dirty coil before it turns into an emergency call, which is almost always the cheaper path.
Leaky ductwork in a Wittmann attic or crawl space can waste a large share of conditioned air before it reaches a vent, and we test and seal as part of a full evaluation.
A thermostat upgrade is one of the cheapest efficiency improvements available, and we check compatibility with your existing Wittmann system first, not guesswork.
Reversing valve, defrost cycle, and auxiliary heat all need specific diagnostic steps a general repair call doesn't cover, not treated like a standard split system.
A real Manual J load calculation before recommending equipment size, not a square-footage guess, so the new Wittmann system performs the way it's rated to.
Manometers and anemometers measure what's actually happening in the ductwork instead of guessing from symptoms on comfort complaints.
Wittmann businesses running packaged rooftop units get the same diagnostic rigor as residential split systems as anything else we service.

Four steps, no surprises.
Tell us what's happening — no phone tree to fight through.

What doesn't change job to job.
The price we quote is the price on the invoice.
Local trucks mean fast arrival, not a multi-day wait.
No exceptions on licensing or coverage.
We come back and fix it, free, within the warranty window.

Round-the-clock availability, answered live.
The numbers behind the diagnosis are yours to see.
What you read is what happened.
Faster parts mean faster repairs.
No-heat and no-cool calls jump the schedule during extreme weather, not left for the next opening.
Every visit gets logged, so the next technician isn't starting from zero on your Wittmann system, visit to visit.
Nobody shows up who doesn't work directly for us.
You know who's coming, when, and what it costs before anyone walks in the door.
Consistent contact for repeat commercial customers.

If a repair we complete doesn't hold up, we come back and fix it at no additional cost, inside the warranty period we quote you upfront.
Warranty on file, no fine print
