“Our Air conditioner stopped working the day before a huge party on the hottest day. Josh came out first thing in the morning and installed the part. We joined their HVAC plumbing maintenance and they came back and maintenance the HVAC and then the plumbing guy came and flushed the water heater and did maintenance as well as check flow of house water. The are great people friendly polite and fairly priced. There is great follow up and quick response to questions. Best customer service I have encountered in a long time. It is a forgotten art.”

What customers say about AC Installation
AC installation questions we hear most
Find answers to common plumbing and HVAC questions from our expert team.
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.
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.
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.
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.
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.
