When the air conditioning stops keeping up or the heat comes on weak, the answer is the same whether the fix is a single component or a full system swap: get someone out who can look at it and tell you what it actually needs. We handle that work across Lakeway, from diagnosing a fault in an existing unit to pulling out aging equipment and putting in a new system sized correctly for the space. Residential customers, property managers with rental units, and small commercial operations all call for the same core reason: something is not working the way it should, and they want a straight answer on what to do next.
Lakeway is a town where the housing stock skews toward larger homes, and larger homes ask more of HVAC equipment. More square footage to condition, more ductwork to move air through, and more zones where comfort can go wrong. We work on central air systems, heat pumps, ductless mini-splits, gas furnaces, and the controls that tie everything together.

A thermostat set to the wrong mode is the most common reason a system seems to have stopped working. Check that it is set to heat or cool as appropriate, that the fan is set to auto rather than on, and that the temperature setting is actually calling for the system to run. A thermostat that has lost its settings after a power interruption can behave as though the system has failed when the fix is a two-minute reset.
The filter is the next thing to look at. A filter that has not been changed in several months can restrict airflow enough to cause the system to shut down on a safety limit, freeze the evaporator coil, or simply move too little air to condition the space. Pull it out and hold it up to the light. If you cannot see through it, replace it before calling.
The air handler has a power switch nearby that looks like a standard light switch. It gets bumped off more often than it should. The outdoor condenser has a disconnect box on the wall beside it. Both are worth checking before assuming the fault is inside the equipment. If the circuit breaker for the HVAC system has tripped, reset it once. If it trips again, stop there and call us. A breaker that keeps tripping is pointing at a fault in the equipment, not in the breaker.
Leaking ducts are one of the most common reasons a home in this region feels uneven from room to room. Conditioned air that escapes into an attic or a wall cavity before it reaches a register is air the system worked to produce and the homeowner paid for. The system runs longer to compensate, the rooms at the end of the run stay warmer or cooler than they should, and the equipment wears faster than it otherwise would.
The good news is that most duct problems do not require pulling the house apart. A duct inspection identifies where the losses are. Accessible joints and connections can be sealed without major disruption, and the improvement in room-to-room comfort is often noticeable immediately. We also look at how the ductwork is balanced. A system that delivers too much air to one zone and too little to another can often be adjusted at the register or damper level rather than requiring new ductwork.
For homes with rooms that have never been comfortable regardless of what the system does, the ducting layout is usually the place to start. We will look at the system and tell you what it needs.
The rate for the diagnostic visit is explained on the call, before the visit is confirmed. Once the technician has looked at the system and identified the fault, a repair quote is given before any parts are ordered or work begins. You know the number before you say yes to anything.
What moves a quote is the nature of the fault, where it sits in the system, and whether a repair is the right answer or whether the equipment has reached the point where replacement makes more economic sense. A compressor fault on a unit that is well past its service life lands differently than the same fault on a system that is a few years old. The scope of the work, what has to be accessed, and what parts are involved all factor in. A replacement quote covers the equipment and the installation, and it is confirmed once the system is scoped on site.
We do not give a final number before the system has been looked at, because a number given without seeing the equipment is a guess. What you do get on the call is the diagnostic rate, a clear explanation of how the quote process works, and a scheduled time for the visit. The diagnosis gets explained on every call, so you are not waiting and wondering what was found.
A thermostat that is fifteen years old may still turn the system on and off, but it is likely doing it less accurately than it should. Older mechanical and basic digital controls can read temperatures several degrees off from the actual room temperature, which means the system runs longer than necessary or shuts off before the space is comfortable. Replacing the control is a straightforward job and sometimes produces a noticeable improvement in comfort without touching the equipment at all.
Modern programmable and smart thermostats go further. They allow the system to run on a schedule that matches how the home is actually used, which reduces the load during hours when nobody is there and brings conditions back to comfortable before people arrive. For a home with a heat pump, the thermostat needs to be compatible with the heat pump's control wiring, which is different from a standard furnace setup. We confirm compatibility on the call before scheduling an installation, and the new control is calibrated to the equipment before the visit is closed out.
Scheduling a visit starts with a phone call. The job is scoped on the phone, the rate is confirmed, and a time is set. We are available every day from 5:30 AM to 9:00 PM, which covers early-morning calls before work and evening calls after it. When a system has stopped working entirely, that call gets treated as urgent and we work to get someone out as quickly as the schedule allows.
For a rental property, a business, or any space that cannot simply be closed while the work happens, the visit is set up around that constraint. Access arrangements, the scope of the work, and any timing considerations are all discussed on the call before the visit is confirmed. If the property will be occupied during the visit, the technician who comes out knows that going in. We keep you informed from diagnosis to final test, so there are no gaps in what you know about where the job stands.
A system that cools less effectively over time, or one that freezes up at the evaporator coil, is often losing refrigerant. The diagnosis involves checking pressures, identifying where the loss is occurring, and repairing the leak before recharging the system. Topping up refrigerant without finding the leak is a short-term fix that does not hold. We find the source and address it.
Rooms that stay too warm or too cool despite a functioning system often have an airflow distribution problem rather than an equipment fault. Adjusting dampers, checking register positions, and verifying that the system is delivering the right volume of air to each zone can resolve comfort complaints without any repairs to the equipment itself.
Joints that have separated, flex duct that has kinked or collapsed, and connections that were never properly sealed are all common findings in homes that have had additions or renovations. We locate the losses, repair what can be reached, and seal the connections. The improvement in system efficiency and room comfort is often significant.
A furnace that starts and then shuts off after a few seconds is usually responding to a fault at the ignition or flame sensor. The flame sensor reads whether the burner has lit and shuts the system down as a safety measure if it does not detect a flame. A sensor that is coated with residue will fail to read correctly even when the burner is working. Cleaning or replacing the sensor is a targeted repair that restores normal operation.
Larger homes with multiple levels or distinct living areas can benefit from a zoning system that controls temperature independently in different parts of the building. A zoning setup uses dampers in the ductwork and a controller that manages which zones are calling for conditioning at any given time. For a home where one floor is always too warm while another is comfortable, or where a home office needs different conditions from the rest of the house, zoning is worth discussing on the call.

The notice needed depends on the equipment selected and its availability. Some replacements can be scheduled within a few days. Others, particularly for less common equipment configurations, may require more lead time for the equipment to be sourced. The timeline is confirmed on the call once the scope is established and the equipment is identified.
Not necessarily, but it depends on the component and the age of the system. A capacitor failure on a ten-year-old system does not automatically mean the compressor is next. A heat exchanger that has developed a crack on a system of the same age is a more significant finding that changes the repair-versus-replace calculation. The technician will explain what the failed component tells you about the overall condition of the system, not just what it takes to fix the immediate fault.
The comparison is always part of the conversation after a diagnostic. What the repair involves and what it costs, set against what a replacement would involve and what that costs, is explained clearly before any decision is made. If you need that information in writing for a property file or a landlord approval, let us know and we will confirm what documentation the visit produces.
After installation, the equipment documentation, including the manufacturer paperwork that came with the unit, is handed over. The system is commissioned and tested before the technician leaves, and the thermostat and controls are confirmed to be operating correctly. Any questions about the new equipment are answered before the visit closes out.
It does, and it matters more than most people expect. A system that is undersized for the square footage runs continuously without reaching the set temperature. A system that is oversized short-cycles, which means it shuts off before it has run long enough to manage humidity properly. The right equipment size is calculated from the actual load of the space, including the layout, insulation, and window area, not from a rule of thumb. That calculation happens before anything is quoted or ordered.
If the technician spots a secondary issue while addressing the primary fault, it is noted and explained before leaving. Whether to address it in the same visit or schedule a follow-up depends on the nature of the issue and whether the scope of the original call covers it. Nothing additional is done without your authorization.
Yes. Rental properties and multi-unit situations are a regular part of the work we do in this area. When you call, let us know the property type and any access considerations, and we will set up the visit accordingly. Pricing is confirmed before the visit is scheduled, and the scope of the work is explained clearly so there is nothing to sort out after the fact.
A straight answer on repair against replacement is part of the call. Once someone has actually looked at the equipment, the picture is clear: what it will take to repair it, what a replacement would cost, and which answer makes more sense for where the system is in its life. That is the conversation we have on every job where the question comes up.
Call (737) 353-9556 and we will get it scheduled. We are available every day from 5:30 AM to 9:00 PM.
