When equipment is aging or a renovation is in the works, getting ahead of the problem is always cheaper than waiting for a breakdown. A homeowner planning a room addition, a property manager whose units are running on aging condensers, a business owner who knows the rooftop unit is on borrowed time: those are the calls we are ready for. We handle heating and cooling across Schertz and Guadalupe County, from a single-system repair to a full replacement planned months in advance.
That kind of planning call is where the work goes smoothest. You get the diagnosis explained before anything is scheduled, a clear picture of what the job involves, and a price confirmed before a visit is booked. Whether the system is fifteen years old or five, the age of the system changes the answer, and that gets said.
A duct system that was installed without care, or one that has developed leaks over years of use, does not just reduce comfort. It makes the equipment work harder than it was sized to, which shortens the life of the compressor and the blower motor and raises the energy cost of every hour the system runs. In a city like Schertz, where homes range from newer builds to properties with ductwork that has never been properly assessed, this is one of the more common causes of high bills and uneven temperatures.
The fix does not require pulling walls apart. Duct sealing addresses the leaks at the joints and connections, and a proper airflow assessment identifies which rooms are undersupplied before any work starts. When the problem is a duct run that was never sized correctly for the space it serves, that gets identified in the diagnostic rather than discovered after the fact.
Uneven temperatures from room to room are one of the clearest signs of a duct problem, though they can also point to a system that is not sized correctly for the load, or a blower that is not moving enough air through the supply side. We work through the likely causes before recommending a fix. Airflow balanced rather than left to chance means the conclusion is based on what the system is actually doing, not on a quick visual check.
An efficiency rating on a piece of equipment describes what it can do under controlled conditions. What a property actually sees once the system is installed and running depends on how well the equipment is matched to the space, how the duct system delivers the conditioned air, and whether the thermostat and controls are set up to take advantage of what the equipment offers.
A high-efficiency system installed with undersized ductwork, or set up on a thermostat that cannot manage its operating modes, will not perform to its rating. The installation and the setup matter as much as the equipment choice. When we scope a replacement or a new installation in Schertz, the conversation covers all three: the unit, the ductwork it connects to, and the controls that run it.
For heat pumps in particular, the efficiency story changes with the season. A heat pump that handles both heating and cooling from a single outdoor unit can run very efficiently through a mild winter, but the setup has to match the home's actual load. We size the equipment for what the space requires, not for what the old unit was rated at.
The call goes faster when you know a few things about the system: the make and model of the outdoor unit if it is accessible, roughly how old the equipment is, and what it has been doing or not doing. If the system is not turning on at all, that is useful. If it is running but not cooling or not heating, that tells us something different. If there is a specific room or zone that is the problem, note that too.
You do not need to have all of this. The person who picks up knows the trade and can scope the job from a description of the symptom. No pressure and no gimmicks, just straight HVAC answers.
We are available every day from 6:00 AM to 9:30 PM. When you call, the scope and the price are settled on the call before anything is scheduled. For emergency no-heat and no-cool situations, we prioritize those calls and take short-notice work regularly. We do not quote arrival windows, but the call confirms what is available and what the visit will cover.
The honest answer is that it depends on what the job turns out to be. A refrigerant leak diagnosis is a different scope from a full system replacement, and a capacitor swap is a different scope from an air handler overhaul. The fault, what has to be reached to fix it, and whether a repair or a replacement is the better answer are the things that move the price.
What does not change is the process. When you call, you get the rate on the phone. The price is confirmed before the visit is scheduled, and you can ask what the visit covers and get a straight answer. Nothing moves forward until you know what you are agreeing to.
We do not offer a free estimate as a standard lead-in. The diagnostic is part of the visit, and the cost of that visit is confirmed on the call. If the diagnostic changes the scope, that gets explained before any additional work is done. For a fuller picture of the job, see the list of HVAC services we handle.
When the system is down and the house is not cooling in the middle of a Texas summer, waiting until a convenient slot opens up is not an option. We take emergency calls every day from 6:00 AM to 9:30 PM for no-heat and no-cool situations. The call covers what the system is doing, what the visit involves, and what it costs before anything is booked.
For tenants and businesses that have to stay open, the visit is scoped with that in mind. The technician who arrives works through the diagnostic and the repair with the property's needs in the frame. If the job is going to take longer than a single visit, that gets communicated clearly rather than discovered at the end of the day.
Planned maintenance and seasonal tune-ups can be scheduled at a time that works for the property. A spring tune-up before the long cooling season, or a fall check before the heating season, is the kind of appointment that keeps a system out of the emergency column.
Call (830) 632-8965 and we confirm what is available when you book.
The compressor is the heart of the cooling system, and when it starts drawing too much current, running hot, or not building pressure, the whole system feels it. A condenser that is not shedding heat efficiently compounds the problem. These faults show up as a system that runs constantly without reaching temperature, or one that trips the breaker repeatedly. We diagnose both before any part is quoted.
These are the components that start the system, keep it running, and shut it down safely. A capacitor that is reading low will let the system start but cause it to run inefficiently or fail to start at all on a hot day when the voltage demand is highest. A contactor that is pitting or sticking causes similar symptoms. Control board faults are less common but show up as erratic behavior that does not trace to a single component. Each of these has a diagnostic path, and we work through it.
The air handler moves conditioned air through the duct system. When the blower motor is failing, the first sign is often reduced airflow at the registers, a system that is cooling or heating at the unit but not delivering it to the rooms, or a motor that is drawing high amperage and tripping the limit switch. Cleaning, bearing service, and motor replacement are all part of this work.
A property that has never had central air, or one where the existing system is being replaced entirely, involves equipment selection, duct assessment, and proper sizing for the space. We handle the full installation, from the outdoor condenser to the air handler to the thermostat and controls.
A system that is low on refrigerant is not just less efficient. It runs under conditions it was not designed for, which accelerates wear on the compressor. Leak diagnosis involves pressure testing and tracing the leak to its source before any refrigerant is added. Adding refrigerant without finding the leak is a short-term fix that leaves the underlying problem in place.
When the system is completely unresponsive, the diagnostic covers the thermostat, the control board, the contactor, and the blower circuit before anything else is assumed. A system that will not start is not always a failed compressor. Working through the likely causes in order is how the right answer gets found.
We serve Schertz and the surrounding communities across Guadalupe County and the wider region. That includes Cibolo, Universal City, Selma, Converse, and Live Oak. Calls from any of these areas are handled the same way: scoped on the phone, priced before scheduling, confirmed before anyone is dispatched.
If your address is near Schertz and you are not sure whether it falls within the service area, the call will confirm it quickly. Coverage is not limited to the city limits, and Guadalupe County properties outside the city are part of the area we work in regularly.
Most callers describe the symptom without the context that helps narrow it down. Knowing whether the system is running at all, whether it is producing any heating or cooling, how long the problem has been developing, and what the system was doing just before it stopped are all useful. The more of that you can tell us, the more accurately we can scope the visit on the phone.
Homes in Schertz run their cooling systems hard through a long warm season, which puts steady wear on compressors, capacitors, and blower motors. Refrigerant leaks, airflow problems from aging ductwork, and systems that are undersized for additions or remodeled spaces come up regularly. The diagnostic on the call helps narrow down which category the symptom points to before a visit is scheduled.
Square footage, ceiling height, the number of zones, and the condition of the existing ductwork all factor into how a replacement or new installation is scoped. A proper load calculation is part of the conversation before any equipment is selected, because a system sized for the wrong load will not perform correctly regardless of its efficiency rating. The quote reflects what the property actually requires.
Turn the system off at the thermostat and call us. A burning smell can point to an overheating blower motor, a failing capacitor, or debris that has worked its way into the heat exchanger, and running the system further risks turning a repair into a larger problem.
Yes. Whole-home dehumidifiers, air filtration systems, and UV air treatment equipment all have maintenance requirements separate from the main HVAC system. Filter changes, media replacement, and periodic checks are part of keeping that equipment working correctly, and we can include it in a maintenance visit.
