Manual J Load Sizing
Engineering-grade load calculation for your exact home — not a rule of thumb. The single most important step in getting comfort and efficiency right.
Sized properly. Installed carefully. Backed by warranty.
A new AC system is one of the biggest investments you'll make in your home. The brand matters less than who installs it. AirPros sizes, installs, and commissions residential systems built to handle Alabama heat and humidity — for the next 15+ years.

Trusted by Alabama homeowners, property managers, and facilities teams.
What we do
A new AC is more than a box on a pad. Our installs include the sizing, ductwork, controls, and commissioning that determine how the system actually performs.
Engineering-grade load calculation for your exact home — not a rule of thumb. The single most important step in getting comfort and efficiency right.
16–20 SEER2 single-stage, two-stage, and variable-speed systems from Trane, Carrier, Lennox, Rheem, and other top brands.
We inspect existing ductwork during every install. Leaky ducts waste 20–30% of your output — we seal, balance, or modify as needed.
Ecobee, Nest, Honeywell, and manufacturer communicating thermostats — installed, programmed, and tied to your Wi-Fi.
Heat pumps are increasingly the right answer in Alabama — efficient cooling and heating in one system. We'll model the cost-benefit for your home.
Charge verification, airflow measurement, and refrigerant subcooling/superheat tuning. The difference between a system that lasts 10 years and 20.
We pull permits and coordinate with the city/county inspector when required — so the install is documented and code-compliant.
We haul off and properly dispose of your old condenser, coil, and refrigerant. No mess left behind.
Why AirPros
Two contractors can install the same equipment and produce wildly different results. The difference is in the sizing, the ductwork, and the commissioning — the steps most installers skip to save an hour.
An oversized AC short-cycles, dehumidifies poorly, and dies young. We size to actual load — not a guess based on square footage.
If your ducts are leaky or undersized, even the best equipment underperforms. We diagnose and fix the duct system as part of the install.
Refrigerant charge by subcooling, static pressure measurement, airflow verification. Skipping this is why so many systems fail at year 5.
Manufacturer warranties + AirPros workmanship warranty. One phone number for anything that comes up — for the life of the system.
“Derrick and his team did a great job. From install to following up on the unit, I could not have asked for a better team to take care of our needs.”
A standard residential changeout (replacing an existing system) typically takes one day. New construction installs or full system upgrades with duct modifications can take 2–3 days.
Properly sizing equipment requires a Manual J load calculation that considers square footage, insulation, windows, orientation, and Alabama's specific climate. We do this for every install — it's the single most important factor in long-term comfort and efficiency.
For most homes in Tuscaloosa and Northport, a 16–18 SEER2 variable-speed system is the sweet spot. Higher SEER units cost more upfront but pay back through summer electric bills. We'll model the payback for your specific home.
Yes. Manufacturer warranties typically include 10-year parts coverage when the system is registered. We also back our labor with a workmanship warranty — details vary by equipment and we'll cover them clearly in your proposal.
Absolutely. We do duct sealing, balancing, and modifications during installs. If your existing ductwork is undersized or leaky, we'll fix it — proper airflow is what makes a high-efficiency system actually deliver.
Yes — we work with financing partners to offer flexible monthly payment plans for new installations, often with promotional rates. Ask us during your in-home consultation.
