HVAC System Installation
in Killeen, Temple & Georgetown
Ellis Air Systems installs new heating and air conditioning systems for homes and businesses in Killeen, Belton, Temple, Georgetown and nearby Central Texas towns. New construction and changeouts are different jobs — start with the path that fits the project. Family-owned and operated since 1988, with a lifetime workmanship warranty on our installations.
Four Ways We Install HVAC Systems
Use the page that matches the job. New construction is the first system going into a new building. A changeout replaces a system in a building that’s already there.
Residential New Construction
HVAC for new homes going up in our service area. Written for builders: we talk through sizing, equipment and brands before anything goes in.
Commercial New Construction
New heating and cooling systems for offices, shops and other commercial properties, plus new construction HVAC for builders across Central Texas.
Residential Changeouts
Full system replacements in existing homes, with honest repair-or-replace guidance. Financing through Regions and Microf is available on residential replacements, and we offer free estimates on those jobs.
Commercial Changeouts
Replacing heating and cooling equipment in an existing office, shop or other commercial property, held to the same standards as our residential work.

What’s Included in an Ellis Air Installation
A new system should fit the building, not just match whatever was there before.
Right-sized equipment
The right size depends on square footage, insulation, windows, ductwork and how the space is used. An oversized system can short-cycle and leave the air clammy. An undersized one runs constantly in Central Texas summers. We’ll talk through sizing with you before you choose.
Heat pumps, furnaces and ductless options
We install complete heating and cooling systems, including heat pumps and ductless mini-splits. If you’re weighing a heat pump against a gas furnace, we can walk through what fits the project. See our heat pump repair and installation page.
All major brands
We install and service Amana, Lennox, Trane, Goodman, Rheem, Ruud, Tempstar, American Standard, Carrier, Daikin and all other major brands, so we can match the right equipment to the project and the budget.
Lifetime workmanship warranty
Our installations are backed by a lifetime workmanship warranty. Ask your local office for the details that apply to the job.
How an HVAC Installation Typically Goes
The details differ between a new building and a replacement, but the path is straightforward.
- 1Start the conversation.Call the office nearest you or request service online. Tell us whether this is new construction or a replacement, and what you’re trying to solve: a new building going up, comfort, age or repairs.
- 2Talk through sizing and options.We look at the space and the equipment choices, including brands and how the system should fit the building. If this is a replacement in an existing home and you’re not sure it’s time, start with our repair or replace questionnaire.
- 3Our own crews install the system.We’ve been installing systems since 1988, and experience matters: we know the correct way to put in a system, with no shortcuts.
Financing, Savings and Cool Club
On residential changeouts — replacing a system in an existing home — financing is available through Regions and Microf. See our financing page, or apply for Microf financing. We also offer free estimates on residential system replacements.
Curious how a higher-efficiency system could affect energy use? Try our energy savings calculator. Results are estimates only; actual savings vary.
After a residential replacement, Cool Club is our tiered preventative maintenance membership for homes: two visits a year, a 21-point checkup and cleaning, and 10% off parts (labor not included). Higher tiers include better benefits. Cool Club is not used on commercial properties.
Military members and first responders get 5% off full system replacements plus 10% off repair parts (labor not included). That discount is for residential system replacements and can’t be combined with Cool Club.
Commercial Preventative Maintenance
Ellis Air offers commercial preventative maintenance, including but not limited to filter changeouts and belt replacements. Visits can run monthly, quarterly, bi-annual or yearly. Each job is bid out for that property so we can confirm the right filter sizes and belts and determine how many systems you have. Request service online or call the office nearest the property to schedule an appointment for us to come out and gather the appropriate information to provide you with an accurate proposal.
Financing is not offered for commercial projects or for residential new construction. Need financing? Many businesses and builders arrange equipment financing through their own bank or a commercial lender.
