Trane Comfort Specialist Dealer

Factory-authorized dealer for Trane heating and cooling systems.

HVAC Demo is recognized as a participating Trane dealer, which means our team receives ongoing factory training on the equipment we install and service. Because we work directly with the manufacturer, Austin homeowners get access to current model information, matching system components, and manufacturer-backed warranty registration. It also means replacement parts and technical support are available when you need them, even during the peak summer cooling season.

BBB Accredited Business

Accredited by the Better Business Bureau and committed to its standards.

Accreditation with the Better Business Bureau reflects a commitment to honest advertising, transparent pricing, and responsive customer service. It gives Austin residents an independent place to review how a company handles questions, scheduling, and follow-up on completed work. We maintain that accreditation by addressing customer concerns directly and keeping our business practices straightforward.

Texas Licensed HVAC Contractor

Licensed to perform HVAC contracting work in the State of Texas.

HVAC work in Texas is regulated, and HVAC Demo operates as a licensed contractor under the applicable state licensing requirements. Hiring a licensed contractor protects you from improperly permitted or uninspected installations that can cause problems later at resale. License information is available upon request, and we are glad to provide it before work begins so you can verify our standing with the state.

NATE-Certified Technicians

Technicians certified through North American Technician Excellence.

NATE certification is an industry-recognized credential that requires technicians to pass rigorous testing on heating, cooling, and air distribution systems. It is not a one-time formality — certified technicians must recertify to stay current with equipment changes. For Austin customers, that means the person diagnosing your system understands how it should perform in our long, hot cooling season and can explain the findings in plain language.

EPA 608 Certified Refrigerant Handling

EPA Section 608 certified for safe refrigerant handling and recovery.

Refrigerant is regulated at the federal level, and our technicians hold EPA Section 608 certification to legally and safely handle it. This matters to Austin homeowners because improper refrigerant charging reduces efficiency and can shorten the life of a compressor. Certified handling means your system is charged to the manufacturer's specification and refrigerant is recovered and disposed of properly.

Written Parts & Labor Warranty

Workmanship warranty provided in writing with every installation.

Every installation we complete includes a written workmanship warranty in addition to the manufacturer's equipment coverage. Equipment warranties often cover the parts but not the labor to diagnose and replace them, which is where a workmanship warranty helps. If something related to our installation needs attention, you have a documented point of contact and a clear process to request service under warranty.

Flexible Financing Options

Payment plans available for repairs and full system replacements.

Air conditioning failures in Central Texas rarely happen at a convenient time, and a full system replacement is a significant expense. We offer financing options through third-party lending partners so qualified customers can spread the cost over time instead of paying the full amount upfront. Applications are handled through the lender, and our team can walk you through the available terms before you commit.

Insured & Background-Checked Team

Carrying general liability and workers' compensation coverage.

HVAC Demo maintains general liability and workers' compensation insurance so that homeowners are not exposed to liability if something is damaged or someone is injured on the job. Every technician who enters your home goes through a background check before being sent into the field. That combination gives Austin customers confidence that the person at the door has been vetted and that the company is properly covered.

AC Installation

High-Efficiency AC Installation for a 1970s Mueller Bungalow

Mueller, TX

HVAC Demo replaced a failing 18-year-old central air conditioner with a properly sized high-efficiency system for a single-story bungalow near Mueller.

Outcome: The home now holds 74 degrees through the hottest part of the afternoon without the system running continuously. The homeowner reported a noticeably lower electric bill the first full month after installation and said the house felt more even from room to room. Static pressure readings came in within the manufacturer's recommended range, and the new equipment registered for a 10-year parts warranty. The client called the process straightforward and appreciated the load calculation being explained before any equipment was ordered.

Ductwork Replacement

Full Ductwork Replacement in a Cedar Park Ranch Home

Cedar Park, TX

HVAC Demo replaced crushed and disconnected flex duct throughout a Cedar Park ranch home to fix uneven temperatures and high summer energy use.

Outcome: Temperature variance between the front and back of the house dropped to about two degrees, which the homeowner confirmed over several weeks of summer weather. Measured duct leakage fell by more than half, and the runtime on the existing air conditioner decreased noticeably during peak hours. The homeowner remarked that the back bedrooms finally felt like part of the same house. The attic ductwork was photographed before and after so the client could see exactly what had been corrected.

Commercial HVAC Retrofit

Commercial HVAC Retrofit for a South Congress Retail Building

South Congress, TX

HVAC Demo retrofitted a multi-tenant retail building on South Congress with new split systems and a controls overhaul to resolve persistent comfort complaints.

Outcome: Tenant comfort complaints dropped to zero over the following cooling season, and both businesses stopped using portable heaters and fans. The property manager can now see runtime and setpoints for every unit remotely and address issues before they become complaints. Building energy use per square foot declined compared to the prior year despite a hotter summer. The owner has since asked HVAC Demo to quote a similar retrofit on a second property.

For most residential system replacements in the Austin area, our HVAC technicians complete the work in one to two days. The exact timeline depends on the type of system, where the equipment is located, and whether any additional work is needed. A straightforward changeout of an attic air handler and outdoor condenser is usually a single-day project, while a system that also requires duct modifications, new electrical circuits, gas line adjustments, or a transition from one equipment type to another can stretch to two or three days. If ductwork is being replaced or a system is being installed in a new addition, plan on three to five days. The process starts with an in-home assessment. We look at the size and layout of your home, windows, insulation levels, and existing ductwork, then run a room-by-room load calculation rather than simply matching the size of your old unit. Oversized equipment is one of the most common causes of humidity problems and short cycling in Central Texas, so getting the sizing right matters. From there we put together a written proposal that outlines equipment options, efficiency ratings, the scope of work, and any permits that will be pulled. Many jurisdictions in and around Austin require a permit and inspection for HVAC replacement, and we factor that scheduling into the plan. On installation day, our team protects floors and walkways, removes and disposes of the old equipment, sets the new indoor and outdoor units, runs or flushes refrigerant lines, installs the thermostat, and verifies refrigerant charge, airflow, and temperature differential before we call the job complete. We then walk you through the new system, show you how to manage the filter and thermostat settings, and confirm that the equipment warranty has been registered. Keep in mind that during the peak cooling months of June through September, scheduling lead times are longer, so booking early is always a good idea.

The decision usually comes down to age, repair history, efficiency, and what the repair actually fixes. Most residential air conditioners and heat pumps have a realistic service life of roughly 10 to 15 years, and in Austin, systems work hard because the cooling season is long and attic temperatures are extreme. If your equipment is in that age range and has needed two or more significant repairs in the past few years, replacement typically makes more financial sense than continuing to patch it together. If the system is under eight years old and the problem is a failed capacitor, contactor, blower motor, or thermostat, a repair is almost always the smarter choice. We also look at what the repair involves. A refrigerant leak in an older unit that uses discontinued refrigerant can be an expensive and recurring problem, because the cost of the refrigerant itself keeps climbing and the leak may return. A failed compressor on an aging system is another situation where replacement is often the better path. On the other hand, a clogged condensate drain, a dirty evaporator coil, a failed run capacitor, or a bad thermostat are straightforward fixes that restore full performance without a major investment. Efficiency is the third factor. Older systems may run at efficiency levels far below what is available today, which means higher monthly utility bills year after year. When we compare the cost of a repair against the energy savings and the fresh parts-and-labor warranty that come with a new system, the math often favors replacement for older equipment. During our visit we will give you an honest assessment of both options, including what we expect the remaining life of your current system to be, so you can decide with clear information instead of pressure.

Coverage depends entirely on your policy and the cause of the damage, so the first call should always be to your insurance agent or adjuster. That said, the most common insurance-related HVAC issue we see in Austin is water damage from a clogged condensate drain line or an overflowing drain pan. In humid Central Texas summers, condensate production is heavy, and when a drain clogs, water can soak ceilings, drywall, insulation, and flooring near an attic air handler. Many homeowner policies will cover resulting water damage when the event is sudden and accidental, but they frequently exclude damage caused by a lack of routine maintenance, which is why keeping records of filter changes and annual service visits matters. If water or fire damage does occur, we can help you document it. Our HVAC technicians take photos of the affected equipment, note moisture conditions, identify the failed component, and provide a written summary you can hand to your adjuster. Having a clear cause-and-effect explanation often makes the claims process smoother, because the adjuster can see whether the damage originated from the HVAC system or from a plumbing or roof issue. We can also separate the cost of repairing or replacing the equipment from the cost of repairing the structure, since those are handled differently under many policies. We are not insurance professionals and we cannot tell you what your policy will or will not pay, so please treat any general information here as a starting point rather than advice about your specific claim. What we can do is respond quickly to stop ongoing water intrusion, make the system safe, and give you the documentation you need. If your system was damaged by a storm or a fire, we will also help you evaluate whether repair is realistic or whether replacement is the more sensible route for your home.

Start by asking for the license number and verifying it. In Texas, air conditioning and refrigeration contractors are regulated by the Texas Department of Licensing and Regulation, and you can look up a contractor's status directly through the state's online database. A legitimate company will give you that number without hesitation. It is also reasonable to ask whether the individuals who will actually be working in your home hold the appropriate technician credentials, since the people on the truck matter as much as the company name on the invoice. Insurance is the second thing to confirm. Ask for a certificate of insurance showing general liability coverage, and ask whether the company carries workers' compensation coverage for its employees. This protects you if someone is injured on your property or if your home is damaged during the work. If a contractor uses subcontractors, ask how those crews are screened and insured as well. A quick phone call to the insurance carrier listed on the certificate can confirm that the policy is active and covers HVAC work. Beyond paperwork, look at local experience and process. A contractor who regularly works in Austin should understand attic installations, slab foundations, long cooling seasons, humidity control, ductwork common in older Central Texas homes, and the permit requirements of the city or county where you live. Ask for a written proposal that includes equipment model numbers, efficiency ratings, the scope of work, and warranty terms. Ask for references from recent jobs and, if you want extra confidence, check for complaints through local consumer protection channels. We are happy to answer these questions about our own operation and to point you toward the documentation you should request from any contractor you are considering.
