AC Replacement in Westlake, TX

About Our AC Replacement Services in Westlake
Westlake homes aren't cookie-cutter, and AC replacement here isn't a one-size-fits-all job. We're talking about houses with multi-zone systems, larger square footage, mature tree canopy that affects sun exposure, and original ductwork that may need attention before a new unit can perform properly. Our technicians take the time to evaluate the full picture before recommending anything — system sizing, duct condition, airflow, and electrical capacity all factor into a replacement that actually works for your home.
Cold is on the Right has worked in Westlake long enough to know what these homes need. Whether your system is a 20-year-old unit that's been patched one too many times or a setup that never cooled your upper floor effectively, we'll build a replacement plan around your home's specific layout and your family's expectations. You'll get upfront pricing and a technician who can explain the work in plain terms — not upsells and pressure tactics.

AC Replacement Services We Provide in Westlake
Full AC System Replacement
When your existing unit has reached the end of its useful life, we handle the complete removal and installation of a new system. For Westlake homes — many of which have larger footprints and higher ceilings — proper sizing is critical to avoiding the hot spots and humidity problems that an undersized or oversized unit creates. We match equipment to your home, not just the tonnage on the old unit's data plate.
System Sizing and Load Calculation
Older Westlake homes were often fitted with HVAC systems based on rough estimates rather than formal load calculations. Before we install anything, we perform a proper Manual J calculation to account for your home's insulation, window exposure, ceiling height, and floor plan. Getting this right from the start is what separates a system that performs from one that runs constantly and never quite cools the house.
Ductwork Evaluation and Repair
Ductwork in homes from the 1970s through 1990s can be leaky, undersized, or routed in ways that limit airflow through certain rooms. Before installing a new AC unit, we inspect the existing duct system to identify any issues that would compromise performance. Replacing the equipment without addressing duct problems is a common mistake — one that leads to disappointed homeowners and a system that underdelivers from day one.
Multi-Zone System Replacement
Many larger Westlake properties rely on zoned HVAC systems to manage cooling across multiple levels or wings of the home. Replacing a multi-zone setup requires coordination across thermostats, zone dampers, and air handlers — not just swapping out the condenser. Our technicians are familiar with these more complex configurations and can replace or upgrade zone components as part of the overall project.
High-Efficiency System Upgrades
Upgrading to a high-SEER system can make a meaningful difference on energy bills in a larger home that runs its AC most of the year. We carry and install equipment from leading manufacturers and help you compare options based on efficiency ratings, warranty coverage, and performance in Texas heat. A well-chosen upgrade often pays for itself over time through lower monthly costs.
Heat Pump Replacement
Heat pumps are an increasingly popular choice for Westlake homeowners looking to handle both heating and cooling with a single efficient system. Modern heat pump technology performs well even in Central Texas summers, and replacing an aging heat pump with a current-generation unit can deliver significant efficiency gains. We evaluate your existing setup and help you decide whether a heat pump replacement makes sense for your home.
Learn MoreFull HVAC System Replacement
When both the cooling and heating sides of your system are aging, replacing them together often makes more sense than replacing components piecemeal. A matched system runs more efficiently, qualifies for better warranties, and eliminates the mismatched performance that comes from pairing old and new equipment. We can manage the full scope of an HVAC replacement from evaluation through final testing.
Learn MoreAC Repair vs. Replacement Consultation
Not every failing AC needs to be replaced — and not every repairable AC is worth fixing. We give Westlake homeowners an honest read on where their system stands, what a repair would cost, and how that stacks up against the long-term value of a replacement. There's no pressure to go one direction or the other; we just give you the information you need to make a confident decision.
Learn MoreNew AC Installation
Whether you're adding cooling to a space that previously didn't have it or installing a system in a new addition, we handle new AC installations throughout Westlake. We assess the space, recommend appropriate equipment, and install everything to manufacturer spec. This includes all electrical connections, refrigerant charging, and a full system test before we leave.
Learn MoreThermostat and Control Upgrades
Replacing your AC is a natural time to upgrade your thermostat and control system. Modern smart thermostats can improve comfort, reduce energy waste, and give you better visibility into how your system is running. We install and configure thermostats from leading brands and make sure the controls are properly integrated with your new equipment before the job is done.
Post-Replacement Maintenance Planning
A new AC system is a significant investment, and routine maintenance is what protects that investment over time. After installation, we walk you through a maintenance schedule tailored to your equipment and Westlake's climate conditions. Regular service catches small issues before they become expensive problems and keeps your system running at peak efficiency through years of Texas summers.

We Know Westlake Homes
Westlake is full of well-built homes from the 1970s through the early 2000s — houses with quality bones, generous square footage, and original systems that have been running for decades. What we see consistently in this neighborhood is HVAC equipment that was top-of-the-line when it was installed but is now well past its useful life, often propped up by a series of repairs that added cost without adding reliability. The mature tree canopy is beautiful, but it also means these homes have variable sun exposure that affects how a system needs to be sized and zoned.
We've replaced enough systems in this part of Austin to know the common failure patterns in homes of this age — from undersized ductwork that was never updated to meet the demands of later additions, to multi-zone setups where the controls and dampers have outlasted the equipment they were designed to manage. That familiarity means we spend less time figuring out what we're dealing with and more time getting the work done right. When you call Cold is on the Right, you're getting technicians who have been in Westlake attics and mechanical rooms before.

High Fives from Austin Homeowners
Graysen and Andrew from Cold is on the Right came out just a couple hours after I called and took care of cutting out my kitchen faucet. They were professional, friendly, and clearly knowledgeable, explaining everything in a straightforward way without any upselling or confusion. It was refreshing to get honest answers and excellent service so quickly. I’ll definitely be using them again for future plumbing needs.
Services: Faucet repair
Price assessment: Reasonable price
We contacted Cold is on the Right today with an urgent plumbing need. Their very professional and organized crew arrived within 30 minutes and fixed our issue. We called five other plumbing companies before them and no one was able to help us. Cold is on the Right will now be the first plumbers we call.
Services: Drain cleaning
We called due to slow drainage and apparently main line backing up into master bathroom shower and sink. There is an automated line that takes your information and apparently works very well. Plumbers Billy and Jeremy showed up promptly after we were informed they were being dispatched this morning, they stayed and worked until the problem was solved and advised on possible future repairs that would need to be done. They were professional, smart, respectful of our home, and efficient in their actions. Let us know what things would cost and were honest in their assessment of what would be needed next and how (un) likely our homeowners insurance would be able to help. I appreciate the service and the fair treatment by these gentlemen. Thank you.
Santiago and Kyle were amazing during our total HVAC system replacement. Kind, informative, knowledgeable and careful to ensure a smooth install. They were efficient and got my AC working before my family arrived for spring break. Now enjoying the cool air with family. Great pricing and quick turn around from quote to finished job. Thank you! 10/10 would recommend them to anyone needing HVCA or plumbing work.
These guys are prompt and very polite, and explain your options well without trying to upsell. We thought we needed three things replaced, but they showed us that one of the three just needed an adjustment rather than a replacement. Wonderful service!
