Signs Your Home Needs a New Central AC System
Most homeowners searching for central ac installation near me Houston aren’t shopping for a new system, they’re trying to figure out why the old one struggles. Here’s what our technicians actually see on service calls before a central ac setup becomes necessary.
- Rooms cool unevenly, even with the thermostat set correctly
- Energy bills climb month over month without a change in usage
- The system is 12 to 15 years old or older
- Your AC still uses R-22 refrigerant, which is being phased out and costly to recharge
- Repairs are becoming frequent, and each one costs more than the last
- The unit runs constantly but never quite reaches the set temperature
Our Central AC Sizing Process (Manual J Load Calculation)
A lot of central air conditioner installation quotes in Houston still come from a quick square footage guess, and that’s how homeowners end up with a system that short cycles or never controls humidity right. Houston’s heat and moisture load a house differently than a dry climate does, so square footage alone tells you almost nothing about the tonnage a home actually needs.
Every central air conditioner installer in Houston at 75 Degree AC starts with a Manual J load calculation, factoring in insulation, window count, orientation, and ductwork condition before we recommend equipment. That number, not a rule of thumb, is what your installation quote is built on.
The Central AC Installation Process, Step by Step
Every central AC installation in Houston we complete follows the same eight stages, so you know exactly what to expect from the first call to the final walkthrough.
In-Home Consultation
We inspect your current system, ductwork, and home layout to understand what a proper central ac setup requires.
Manual J Load Calculation
Our technician calculates the exact cooling load your home needs, based on square footage, insulation, and window exposure.
Equipment Selection
We recommend systems and SEER2 ratings that match your load calculation and your budget, not one size fits all units.
Ductwork Inspection
Existing ductwork is checked for leaks, damage, or sizing issues that would limit the new system's performance.
Permit Pull
We handle the required City of Houston or county mechanical permits before any installation work begins.
Install Day
Our licensed technicians remove the old unit and install the new system, following manufacturer specs and local code.
Startup and Testing
We test refrigerant charge, airflow, and thermostat function to confirm the system runs at full efficiency.
Final Walkthrough
We review the completed installation with you, explain the warranty, and answer any remaining questions on site.
Licensing, Permits & Code Compliance
Every central air conditioner installer on our team holds an active TDLR Air Conditioning and Refrigeration license, and 75 Degree AC carries the liability insurance TDLR requires for licensed contractors. We don’t cut corners on paperwork because unlicensed installation work can void warranties and create real safety risks.
Before install day, we pull the required mechanical permit through the City of Houston or your local county office and schedule the inspections that come with it. This keeps your new system legally documented and protects your home’s resale value down the road.
Central AC Equipment & Brands We Install
We install central AC systems from Trane, Carrier, and Lennox, along with other major manufacturers, and every unit we recommend meets or exceeds Texas’s 14.3 SEER2 minimum for our region. Higher-tier systems, typically 16 to 20+ SEER2, cost more upfront but cut cooling bills faster in a climate where your AC runs most of the year. Rather than pushing one brand, we match equipment to your Manual J load calculation, your existing ductwork, and your budget, so the system fits your home instead of forcing your home to fit the system.
Warranty, Support & What Happens After Installation
Every central AC installation in Houston from 75 Degree AC includes the manufacturer’s parts warranty, typically 10 years when you register the equipment within 60 days, plus our own labor warranty covering the workmanship on your install.
During the first year, your system will need one professional tune-up to confirm refrigerant levels, airflow, and electrical connections are holding steady after the initial break-in period. We keep your paperwork, permits, and warranty registration on file, so if a question comes up two or five years from now, you’re not searching for a paper trail on your own.

Central AC Installation Cost in Houston
Central AC installation in Houston typically runs $6,000 to $14,000, depending on system size, SEER2 rating, and whether your ductwork needs repair or replacement. Homes with straightforward access and existing ductwork in good condition land on the lower end, while larger homes or new ductwork push costs higher.
Your final price comes from the Manual J load calculation, not a flat rate per square foot, so two similar-sized homes can quote differently based on insulation and window count. We provide a written estimate before any work begins, and it reflects the actual equipment and labor your install requires.
