Repair or replace?

Know your options before a big repair.

When a compressor or outdoor coil fails, the question is whether to fix the system you have or replace it. Your technician weighs the repair against your system’s age and condition, and gives you a written price for both, so you can choose.

Older systems may use R-22, a refrigerant that was phased out: new systems haven’t used it since 2010, and it hasn’t been made or imported in the U.S. since 2020.

AC and heat pumps

Sized to your home, not a guess.

We install Carrier, Goodman and Lennox, and other brands on request. We service every brand.

Central AC

A new outdoor unit and indoor coil, paired with your gas furnace or electric air handler.

Heat pump

One system that cools in summer and heats in winter, replacing an AC and its electric heat.

Dual fuel

A heat pump paired with a gas furnace, which takes over on the coldest days.

Efficiency is rated in SEER2. The federal minimum in Texas is 14.3 SEER2 for most home air conditioners and heat pumps; your technician walks you through the tiers above it.

Your home’s age

If your AC came with your house, it’s as old as your house.

The year the median home was built in each town we serve. Your technician checks the date on your own system.

What neighbors say about their AC.

“I was very impressed with the prompt reply I got from Brandenburg when my air conditioner went out and it was 100 degrees outside. … The crew of Kyle, Lane, and Josh worked till 8:00 pm at night to finish a very difficult job in one day. They cleaned up and were so helpful and professional. I am very pleased.”

Good questions, clear answers

Before your assessment.

Have a question about your system? Call us at (512) 756-9847.

Is the assessment really free?

Yes. There’s no charge and no obligation. One of our certified HVAC technicians spends about 45 minutes checking your system and measuring your home, then gives you a written price before any work starts.

Do you replace heat pumps too?

Yes. We replace central air conditioners, heat pumps and dual-fuel systems, and help you decide whether a heat pump makes sense for your home.

Which brands do you install?

Carrier, Goodman and Lennox, and other brands on request. We service every brand.

How do I know what size AC system I need?

Proper sizing requires a professional load calculation—not just a guess based on square footage. We evaluate your home's insulation, window placement, ceiling height, ductwork, and local climate data to determine the exact cooling capacity needed. An oversized unit short-cycles and wastes energy, while an undersized unit runs constantly and can't keep up. Getting the size right is the most important part of any installation.

What SEER rating should I look for in a new AC?

Cooling efficiency is rated in SEER2, the federal test used since 2023 (it replaced SEER). The federal minimum in Texas is 14.3 SEER2 for most home air conditioners and for heat pumps. We often recommend a step above the minimum for the best balance of upfront cost and long-term energy use. Higher-efficiency systems cost more up front and use less electricity, which matters given how many months we run AC here in Central Texas.

How long does a new AC installation take?

A standard replacement of the outdoor condenser and indoor evaporator coil typically takes one day. If we're also replacing the furnace or air handler, adding a new thermostat, or making ductwork modifications, it may take an additional half day. We'll give you a clear timeline before we start and make sure everything is tested and running perfectly before we leave.

Will a new AC system work with my existing ductwork?

In most cases, yes—but it depends on the condition and design of your existing ducts. Older or undersized ductwork can restrict airflow and prevent a new system from performing at its rated efficiency. We inspect your ductwork as part of every installation and will let you know if any modifications, sealing, or insulation upgrades are needed to get the most out of your investment.

Do you offer financing for new AC systems?

Yes, we offer flexible financing options to help make a new AC system affordable. We understand that a full system replacement is a significant investment, and we want to make sure comfort is accessible. We'll walk you through all available options, including any manufacturer rebates or utility company incentives that may apply to your installation.
