105°FDesign peak
Jun – Sep · 7-month season
Sized for the August attic, not the May afternoon. 16 SEER2 minimum, two-stage condenser, return-air actually big enough for the blower.
§ 02.00HVAC · TX + OH · Same-day dispatch
When the AC quits at midnight, we send a real truck.
AC replacement, heat pumps, hybrid systems, ductwork that balances, and 24/7 repair from one in-house team. Trucks stocked with 180+ parts so most calls finish in one visit. Flat-rate quote on the porch. Same price weekday, weekend, holiday.
How we size the system
Two states. Four climates. One load calculation per house.
A 1,800 sq ft house in Plano and a 1,800 sq ft house in Akron need almost nothing in common from an HVAC system. Square-footage rules of thumb don’t survive a single August or a single February. Here’s what we actually engineer for, by region and season.
88°FDesign peak
Jun – Aug · humid not extreme
Right-sized so the system runs long enough to dehumidify. An oversized AC short-cycles and leaves the basement clammy.
22°FDesign peak
5 – 10 days a year, mostly shoulder
Heat pump as the primary; gas furnace wakes up only at the 22°F design day. Strip heat is the backup, not the workhorse.
−2°FDesign peak
Dec – Feb · single-digit nights
Cold-climate heat pump that holds capacity below 17°F, dual-fuel cutover wired to your zip-code design temp, oversized return so the duct doesn’t collapse on high stage.
A formal Manual J load calculation — the room-by-room version, not a rule-of-thumb — runs on every change-out before any equipment is quoted.

What stays after the truck leaves
Five artifacts. Five proofs the work was done right.
HVAC work is invisible the day after install. A new compressor looks like the old compressor. So the proof has to be on paper — signed, dated, taped to the door, and filed with the manufacturer. Every job leaves all five.

The room-by-room sizing calculation, in writing, before any equipment shows up. Square-footage rules of thumb don’t survive an attic in August.

Before-and-after duct leakage in CFM, measured at 25 Pa. The number that says whether the new equipment is feeding sealed duct or wasting half its capacity in the attic.

A free walk-through. No pressure, in writing. We run a Manual J load calc, talk through repair-or-replace with the math, and name the cheap fix before the costly one. We won't sell a new system when a $300 part holds. Most quotes back inside 24 hours.
