Professional Air Conditioning Replacement in Houston, TX
75 Degree AC’s licensed technicians handle air conditioning replacement Houston homeowners can verify, from load calculations to final inspection. We size each system to your square footage and ductwork condition instead of quoting a flat price over the phone.
Houston’s humidity and long cooling season wear down AC units faster than in most cities, so we match every replacement to SEER2 standards and your home’s actual heat load. Each install comes with a manufacturer warranty and a permit pulled through the local building department, on record.
Signs Your Houston Home Needs an AC Replacement, Not a Repair
A failing central AC rarely breaks without warning; it shows small signs first that most homeowners miss until the system stops cooling completely.
- Your system is 12 to 15 years old and still uses R-22 refrigerant
- Repair costs have crossed half the price of a new unit
- Energy bills keep rising even with regular maintenance
- Rooms cool unevenly no matter how you adjust the thermostat
- The compressor struggles to start or shuts off during peak heat
- You've called for repairs more than twice this cooling season
If two or more of these apply to your home, request a same-day AC replacement quote in Houston and let a licensed technician confirm whether repair or full replacement makes sense before you spend another dollar on an aging system.
Our AC Replacement Process, Step by Step
Air conditioning replacement in Houston works best when every step follows a clear order, from load calculation to final inspection.
Home Assessment and Load Calculation
We measure your home's square footage, insulation, and window exposure using a Manual J calculation to find the correct system size.
System Selection
We walk you through replacement air conditioners that match your budget, home layout, and Houston's cooling demands.
Permitting and Code Review
Our team pulls the required city or county permits and checks your electrical and ductwork against current code before install day.
Old Unit Removal
We disconnect and remove your old condenser and air handler, then dispose of refrigerant and components according to EPA guidelines.
New System Installation
Our technicians install the new unit, connect refrigerant lines, and seal ductwork joints to prevent air loss and moisture buildup.
Testing, Inspection, and Walkthrough
We test airflow, refrigerant charge, and thermostat function, then walk you through the system before closing out the permit.
Choosing the Right Air Conditioning System for Your Home
Houston’s long cooling season and heavy humidity put more strain on an AC system than most other climates, so tonnage and SEER2 rating both matter more here than elsewhere. A single-stage unit suits smaller homes with steady loads, while two-stage and variable-speed systems handle larger homes and uneven room temperatures better.
We work with trusted manufacturers like Trane, Carrier, and Goodman, matching each brand’s efficiency rating to your home’s insulation and duct condition. Higher SEER2 systems cost more upfront but lower your monthly energy bills, and we’ll show you the real payback period before you decide.
Repair or Replace? We'll Help You Make the Right Decision
Deciding between a repair and a full air conditioning replacement in Houston depends on your system’s age, refrigerant type, and repair history. Our technicians inspect the compressor, coils, and ductwork before giving you an honest recommendation, not just a quote for the most expensive option.
If your unit needs a costly repair or you’re past the point of routine maintenance, request a same-day AC replacement quote in Houston and get a clear comparison of both paths. We’ll show you the numbers side by side, so the final call is yours, backed by real data instead of guesswork.

Frequently Asked Questions
How long does an AC replacement take in Houston?
Most residential AC replacements take 4 to 8 hours for a single system, depending on ductwork condition and access to your attic or unit.
Can I replace my AC during the summer in Houston?
Yes, we install year round, though scheduling early in the season helps you avoid peak-summer wait times.
Do I need a permit to replace my AC unit?
Yes, most Houston-area jurisdictions require a permit for AC replacement, and we handle the application and inspection for you.
How long does a new AC system last in Houston's climate?
A properly sized and maintained system typically lasts 12 to 15 years, though heavy humidity and continuous summer use can shorten that without regular upkeep.
What size AC unit do I need for my home?
The right size depends on your square footage, insulation, and window exposure, which is why we run a Manual J load calculation instead of estimating by square footage alone.
