New System Installs and Replacements
Whether your old system has worn out or you’re adding air conditioning to a home or business, Ellis Air Systems installs complete heating and cooling systems across Central Texas. We’ve been installing systems since 1988, and experience matters: we know the correct way to put in your system, with no shortcuts.
Not sure whether it’s time? If your system is older, needs a major repair or can’t keep up in the summer heat, our repair or replace questionnaire is a good first step, and a technician can give you honest advice.

How We Size and Match Your System
A new system should fit your home, not just match the size of the old one.
Right-Sized for Your Home
The right size depends on your home: its square footage, insulation, windows, ductwork and how you use it. We’ll talk through sizing with you before you choose.
Why Size Matters
An oversized system can short-cycle and leave the air clammy. An undersized one runs constantly in Central Texas summers and struggles to keep up.
Ducts and Comfort
Hot rooms, weak airflow and uneven temperatures can come from ductwork as well as equipment. Tell us about the comfort problems you’ve noticed.

How do I know it is time to replace my AC?
Common signs are an older system that needs a major repair, repeated breakdowns, R-22 refrigerant, rising energy bills and rooms that stay hot or humid. Our repair or replace questionnaire can help, and a technician can give you honest advice.
What size AC does my home need?
It depends on your home’s square footage, insulation, windows, ductwork and how you use it, so the right size isn’t always the same as your old unit. We’ll talk through sizing with you before you choose a system.
Which brands do you install?
We install Goodman, Amana, Daikin, Lennox, Carrier, Rheem, Ruud, Trane and all other major brands. Call your local office to talk about which equipment fits your home.
Do you offer financing on a new system?
Yes. Financing for new systems is available through Regions and Microf. See our financing page or call your local office.
What does the lifetime workmanship warranty cover?
Our installations are backed by a lifetime workmanship warranty. Call your local Ellis Air office and ask for the details that apply to your installation.
