From a single ductless mini-split to a whole-home system, we size, install and maintain, all under one roof. Every service below carries the same quality promise.
No hourly meter, no surprise line items, no “while we’re at it”. You approve one clear quote before a single unit is ordered, so you know the cost up front.
We visit, measure every room and listen to what you actually want. Free, and it stays free.
Equipment, labor and permit, one line, one price. Approved by you before anything starts.
The number lands in writing with a simple promise: if it is not the best HVAC experience you have had, you do not pay.
No mystery math. Four things decide what a comfort system costs, and we walk every one with you before the quote lands.
Whatever the mix, you get one clear quote, in writing, before any work starts.
From a heat-wave AC rescue to a whisper-quiet heat pump and ducts that finally reach the back bedroom, this is the comfort we build across Tulsa every day.
Sized with a real load calculation, tuned register by register, until every room in the house agrees with the thermostat.

Every duct sealed and every unit set level.
No rotating subcontractors. HVAC techs who show up on time, protect your home, and treat every room like their own.

When your site goes live, your crew's real names and photos replace these — we never use stock people.
"Great expedient service, very clean install. Both Tristan and Bret were very professional and went above and beyond."
"I have already posted a review for the installation of the heating and air conditioning. That experience was a thoroughly good one."
"ProThermal came right out for our annual inspection and was so incredibly thorough. Grant was awesome."
"Our system wasn’t cooling and the company we usually use couldn’t get anyone out until Thursday. ProThermal came through."
"Communication and service was excellent with each of the technicians. Grant and James tested and diagnosed the system."
A lot of our work comes from a neighbor who watched us comfort the house next door. If you're in the metro, we're just around the corner.
Free estimates · never a franchise
Find your cityNo mystery in the middle. This is the path the job actually takes, start to finish.
A comfort tech comes out, walks every room, checks your existing equipment, ductwork, and electrical panel, and asks how the house actually feels through the seasons. No sales pressure, just measurements and questions.
We run a Manual J load calculation on your square footage, windows, and insulation to size the system right instead of guessing. You get a written plan that lists the exact equipment, model numbers, and where every unit and vent lands.
One clear quote, itemized, with the efficiency ratings and any Energy Trust of Oklahoma rebates spelled out. The number we write is the quote we give you, and we walk it line by line before you sign anything.
A two- to three-person crew arrives when we said, lays down floor protection, and sets the equipment, refrigerant lines, and ductwork over one to two days. We pull the county permit and keep you posted at each stage.
We commission the system, verify airflow and refrigerant charge, and walk you through the thermostat and filter schedule room by room. You get the manufacturer warranty and our labor guarantee in a folder, and we haul off the old equipment and vacuum up before we go.
Three fields, no account, no pressure. We call back the same business day with a real number.
Book a free estimate in under a minute, or call and talk to a real person right now. Upfront pricing, expert crews, no pressure.
Faster: text us a photo of your furnace or outdoor unit and we reply with a ballpark, usually same day.
