Furnace Replacement in Westlake, TX

Upgrading Aging Furnaces in Westlake's Established Luxury Homes

Many Westlake homes built in the 1970s, 80s, and 90s are still running the original furnace — or close to it. These older systems were built to last, but even premium equipment has a lifespan. When your furnace starts costing more to run than it's worth, Cold is on the Right can replace it with a modern, high-efficiency system matched to your home's size and ductwork. We've worked in Westlake long enough to know these homes, their quirks, and what it takes to do the job right.

About Our Furnace Replacement in Westlake

Westlake is home to some of the most well-built residential properties in the Austin area, but age catches up with every mechanical system. A furnace that was installed when a home was built in 1984 has likely been pushing air through that same ductwork for four decades. Cold is on the Right specializes in replacing older gas and electric furnaces in established Westlake homes, making sure the new system integrates properly with existing ductwork, zoning setups, and any smart thermostat upgrades you may have added along the way.

We don't treat every replacement like a cookie-cutter job. Westlake homes often have unique floor plans, multi-zone configurations, and high-end finishes that require careful installation work. Our technicians take the time to assess your existing setup before recommending equipment, and we'll explain your options in plain terms so you can make a confident decision. Upfront pricing, no surprises, and a clean installation you won't have to second-guess.

Furnace Replacement Services We Provide in Westlake

Full Furnace Replacement

When your existing furnace has reached the end of its service life, we remove the old unit and install a properly sized replacement. We evaluate your home's square footage, insulation, and duct layout to select equipment that will heat your Westlake home efficiently without overworking the system.

High-Efficiency Gas Furnace Installation

Modern high-efficiency gas furnaces can achieve AFUE ratings above 95%, a significant upgrade from the 60-70% efficiency common in systems installed in the 1980s. For Westlake homeowners with larger homes and higher heating loads, the long-term energy savings are substantial. Learn More

Furnace System Assessment Before Replacement

Before recommending a replacement, we thoroughly inspect your existing furnace, heat exchanger, and ductwork. In older Westlake homes, we often find that ducts need sealing or rebalancing before a new furnace can perform at its best.

Ductwork Evaluation and Upgrade

A new furnace paired with deteriorating or undersized ductwork won't deliver the performance you're paying for. We assess the condition of your existing duct system and recommend repairs or upgrades as needed, particularly in homes where the original ductwork is now 30 to 40 years old.

Thermostat and Zoning Integration

Many Westlake homes have multi-zone systems or smart thermostats that need to be properly integrated with a new furnace. We handle all wiring and configuration so your new system communicates correctly with your controls from day one.

Emergency Furnace Replacement

If your furnace fails during a cold front and repair isn't a viable option, we offer emergency replacement service. We'll assess the situation quickly and get a functioning system installed as fast as possible so you're not left without heat.

Furnace Repair vs. Replacement Consultation

Not every struggling furnace needs to be replaced right away. We'll give you an honest assessment of whether repair or replacement makes more financial sense for your specific situation, factoring in the age of the unit, repair costs, and current efficiency. Learn More

Heat Exchanger Inspection

A cracked heat exchanger is one of the most serious furnace problems a homeowner can face, as it can allow combustion gases to enter living spaces. In older furnaces common to Westlake homes, heat exchanger failure is a primary reason replacement becomes necessary rather than repair.

Whole-Home HVAC Replacement

If your air conditioning system is also aging, replacing the furnace and AC together is often the most cost-effective approach. Matched systems perform better, qualify for better warranties, and save you from scheduling a second major project in a few years. Learn More

Heating System Repairs and Tune-Ups

If your furnace isn't quite ready for replacement, our heating repair and maintenance services can extend its useful life and keep it running safely. We service all major brands and can work on systems of any age. Learn More

Post-Installation Performance Testing

After every furnace replacement, we run a full system test to verify airflow, temperature rise, and safe operation before we consider the job complete. We make sure everything is working correctly and walk you through the new system before we leave your property.

We Know Westlake Homes

Westlake's residential neighborhoods are defined by large, well-appointed homes built primarily between the early 1970s and late 1990s. These properties often have complex layouts, vaulted ceilings, and original HVAC systems that were top-of-the-line at the time but are now well past their designed service life. When we open up these systems, we find specific patterns: older multi-speed blower motors, oversized original equipment that was common practice at the time, and ductwork that has loosened at the joints over decades of thermal expansion.

The Hill Country terrain and mature tree canopy that make Westlake so distinctive also create microclimates that can stress HVAC systems differently than other parts of Austin. Homes tucked into shaded lots hold moisture longer, and properties on elevated lots face more exposure to winter winds off the Edwards Plateau. We factor all of that in when sizing and positioning new equipment, and we know which brands and configurations hold up best in these conditions over the long run.

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.

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!

Frequently Asked Questions

How much does furnace replacement cost in Westlake?
Furnace replacement in Westlake typically ranges from $3,000 to $6,500 or more depending on the size of your home, the efficiency rating of the equipment, and whether any ductwork modifications are needed. Larger Westlake homes with multi-zone systems or complex ductwork may fall toward the higher end of that range. High-efficiency units (90% AFUE and above) cost more upfront but generate meaningful savings on monthly heating bills over time. We provide upfront, itemized pricing before any work begins so you know exactly what you're committing to.
How long does furnace replacement take?
Most furnace replacements in Westlake homes are completed in a single day, typically four to eight hours depending on the complexity of the job. Homes with older or non-standard ductwork configurations may require additional time to ensure the new unit is properly connected and balanced. We arrive prepared with the right equipment and complete the installation in one visit whenever possible, including post-installation testing before we leave.
Do I need a permit for furnace replacement in Westlake?
Yes, furnace replacement typically requires a mechanical permit in the Austin and Westlake area, and the work must be performed by a licensed HVAC contractor. Cold is on the Right handles the permitting process as part of the installation, so you don't need to navigate that on your own. Permitted work also protects you during a home sale, as unpermitted HVAC work is a common issue that can complicate real estate transactions in the area.
