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 long cooling season and humidity wear out AC systems more than in most cities. That’s why we match every replacement to SEER2 criteria and the actual heat load of your home. Every installation includes a manufacturer’s guarantee and a permit on file through the local building department.
Signs Your Houston Home Needs an AC Replacement, Not a Repair
A failing central AC doesn’t usually go out suddenly without warning; it exhibits tiny indicators first that most homeowners don’t notice until the system stops cooling altogether.
- 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, get a same-day AC replacement quotation in Houston and let a professional expert evaluate whether repair or full replacement makes sense before you spend another dollar on an aged 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.
The License Matters More on a Replacement Than a Repair
A full system replacement needs a City of Houston mechanical permit, and a permit needs a licensed contractor. Our Texas license is TACLA72152E, a Class A license, which means no tonnage cap on the equipment we can install. Check it yourself at tdlr.texas.gov/LicenseSearch, and run the same search on every other bid you receive.
This is also what protects you later. Unpermitted equipment can complicate a homeowners insurance claim and has to be disclosed when you sell. Every technician we send holds EPA Section 608 Universal certification, which is the federal requirement for handling refrigerant in any system size.
Choosing the Right Air Conditioning System for Your Home
Houston’s long cooling season, along with the high humidity, puts more stress on an AC system than in most other regions; therefore, both the tonnage and SEER2 rating matter more here than elsewhere. A one-stage unit is best for smaller homes with consistent loads. Two-stage and variable-speed equipment is ideal for larger homes and for fluctuating temperatures from room to room.
We partner with reputable brands like Trane, Carrier, and Goodman, matching each brand’s efficiency rating to your home’s insulation and duct condition. Higher SEER2 systems cost more up front but lower your monthly energy expenses, and we’ll show you the exact payback period before you decide.
Repair or Replace? We'll Help You Make the Right Decision
Replacing your air conditioning system in Houston is a big decision, and it is contingent upon the age of your system, the type of refrigerant it uses, and whether it has been repaired before. Our professionals will evaluate the compressor, coils, and ductwork before providing you with a quotation for the most expensive choice and giving you an honest recommendation.
If your unit is in need of an expensive repair, you’re beyond routine maintenance, or you want a simple comparison of both routes, ask for a same-day AC replacement price in Houston. We’ll show you the figures side-by-side so the ultimate call is yours, armed with solid data instead of conjecture.

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.
