Two kinds of calls come in about an HVAC system. One is the system that has stopped entirely: no cooling on a hot afternoon, no heat when the temperature drops overnight, nothing happening when the thermostat is adjusted. The other is the system that is running but not doing its job: the house never gets down to temperature, certain rooms stay stuffy while others are fine, the equipment cycles on and off more than it should. We take both. Whether the call is urgent or whether something has been quietly wrong for weeks, the answer starts the same way: a real conversation about what the system is doing and what the visit will cover.
We handle heating and cooling for homes and businesses across Live Oak and the surrounding area.

A thermostat that is reading the room correctly and communicating with the equipment properly makes a measurable difference in how the system runs. When the thermostat is old, poorly placed, or no longer calibrating accurately, the equipment responds to bad information. A smart control upgrade gives the system better data, allows for scheduling that matches how the space is actually used, and in many cases removes the guesswork from a system that has been running inefficiently for years. Installation is straightforward when the wiring is compatible, and we confirm what is needed before the visit is scheduled.
When the AC does not respond at all, the diagnostic starts at the control side before anything else: thermostat signal, capacitor readings, contactor condition, and whether the outdoor unit is receiving power at the disconnect. A system that trips a breaker and then goes silent is a different starting point from one that simply never responds. The cause is almost never obvious from the outside, which is why the technician works through the likely sources rather than quoting a part before the system has been checked.
Small commercial properties in Live Oak often run packaged rooftop units rather than split systems. When a rooftop unit loses cooling or heating capacity, the diagnostic involves the same refrigerant, airflow, and electrical checks as a ground-level unit, but access and working conditions are different. We handle rooftop unit repair and replacement for small commercial buildings alongside residential work.
A heat pump that is running in heating mode but not producing warm air, or one that is icing up and not clearing on its own, usually has a defrost cycle problem. The reversing valve, defrost control board, and outdoor sensor are the components most likely to be involved. This is a specific fault type that looks different from a standard cooling problem, and diagnosing it correctly matters before any part is ordered.
When the equipment is past the point where repair makes sense, or when a paired system has one side that has already been replaced and the other dragging down its efficiency, a full replacement is the better conversation to have. This region's climate asks for both heating and cooling capacity, and the system needs to be sized for the actual load in the space. Heat pump installations have grown steadily in this part of Texas as mild heating seasons make them a practical alternative to a gas furnace paired with a separate air conditioner. We work through the options on the call and confirm the scope and price before anything is scheduled.
Live Oak is a town with an established housing stock, and older homes carry their own set of HVAC considerations. Equipment that has been in place for fifteen or twenty years may be running on original components that have worn gradually rather than failed suddenly. The efficiency loss tends to be slow enough that it does not register until a utility bill is compared to a recent one, or until a room that used to be comfortable no longer is.
Ductwork in older homes is worth looking at carefully. Ducts that were sized for equipment no longer in the house, connections that have separated over time, or insulation that has deteriorated can account for a significant part of what the system is losing. Airflow balanced rather than left to chance means the replacement or repair is set up to actually work in the space it is going into, not just installed and signed off.
Properties with additions or converted spaces sometimes have duct runs that never properly reached the new square footage. A room that stays warm in summer or cold in winter despite a working system is often a duct problem, not an equipment problem. The diagnostic covers both.
Pricing for HVAC work depends on what the job actually turns out to be, and three things move it more than anything else: what the fault is, what has to be accessed to fix it, and whether a repair or a replacement is the right answer for the equipment in front of the technician.
A refrigerant leak that is accessible at the service port is a different scope from one that requires pulling a coil. A furnace repair that involves a single ignition component is a different conversation from one where the heat exchanger is the problem. These are not things that can be quoted accurately before the system is seen, which is why the price is confirmed after the diagnostic and before any work is agreed to.
What does not change is the process. When you call, the visit is scoped on the phone, the rate is confirmed before anything is scheduled, and the diagnosis explained on every call means you know what the technician found and what the options are before you agree to anything. Pricing set out up front. Code-compliant work. Straight explanations.

When the technician arrives, the visit starts with a walkthrough of what the system is doing. That means looking at the thermostat response, checking the air handler, and getting to the outdoor unit before any assumptions are made about the cause. Short cycling, strange noises and weak airflow each point somewhere different, and the diagnostic follows what the system is actually showing rather than the most common cause for that symptom.
Nothing is quoted until the fault is confirmed. If the repair involves a part that needs to be ordered, that is explained before the visit ends, along with what the next step looks like. If the diagnostic points toward replacement rather than repair, that conversation happens on site with the scope and pricing laid out clearly.
The visit ends with the customer knowing what was found, what was done or what needs to be done, and what it costs. No pressure and no gimmicks, just straight HVAC answers. Anyone sizing up a job in Live Oak may want to read our services page first.
Emergency calls for no heat and no cooling are taken every day from 6:00 AM to 9:30 PM, including weekends. When the system is completely out in a Live Oak home or business, the call is handled the same way as any other: scope the job on the phone, confirm the price, then get someone out. We do not quote arrival windows, but emergency work is prioritized.
For businesses and rental properties that need to stay open or occupied, the visit is scheduled around what the property requires. A commercial space that cannot shut down for a repair and a tenant property where the system needs to be back up by evening are both situations we work around. The call is where that gets sorted out, and nothing is put on the schedule until the customer knows what the visit involves.
Seasonal maintenance calls are worth scheduling before the work gets heavy. A cooling system tune-up before summer means the evaporator coil, refrigerant charge, and blower performance are confirmed before the equipment is asked to run hard for months. A heating check in early fall catches ignition and heat exchanger issues before the first cold front arrives and the schedule fills up. Indoor air quality work, including air filtration and whole-home dehumidification, can be added to either visit or scheduled separately.
We cover Live Oak and the communities around it across Bexar County and the surrounding area. That includes Universal City, Selma, Converse, Windcrest, and Schertz. If your address is nearby and you are not sure whether it falls within the service area, a quick call will confirm it.
Calls about this area are answered by someone who knows the trade and can scope the job on the phone before anything is scheduled. The service area covers both residential and commercial properties across the region.
Yes. A no-heat call, particularly when outdoor temperatures are low, is handled as an urgent situation.

Older housing stock tends to surface a predictable set of issues: refrigerant charge that has dropped gradually over time, blower motors that are drawing more current than they should, and duct connections that have separated in attic spaces. Thermostat faults and capacitor failures are also common in equipment that has been running through multiple Texas summers. The diagnostic covers the most likely causes for the symptom reported before any repair is quoted.
Yes, we take both. Residential calls cover everything from a single-family home repair to a full system replacement. On the commercial side, we handle small office and retail buildings, including rooftop packaged units, and we work around tenants and business hours when the property needs to stay open during the visit. The process is the same for both: scope the job on the phone, confirm the price, then schedule.
A sharp rise in running cost without a change in weather or usage patterns usually means the system is working harder than it should to produce the same result. Common causes include a dirty coil, a refrigerant issue, a failing capacitor, or a duct leak that is losing conditioned air before it reaches the living space. A diagnostic visit is the way to find out which one it is.

|---|---|---|---|
| Full System Installation & ReplacementMost Popular | Load calculation and proper sizingMatched condenser, air handler, and coilRefrigerant line and electrical connectionsSystem testing and airflow verification | Homeowners whose system is aging, requiring repeated repairs, or no longer keeping up with the cooling load | Replacing components from the same equipment generation keeps efficiency ratings accurate and avoids compatibility problems that come from mixing old and new hardware. |
| Seasonal Maintenance & Tune-Ups | Cooling or heating system inspectionCoil cleaning and refrigerant checkBlower and electrical component testingFilter check and airflow assessment | Homeowners who want to catch problems before a season starts rather than during it | Spring is the right window for a cooling tune-up before the long Texas summer. Early fall works for heating. Both windows are before demand for service peaks. |
| Emergency HVAC Service | No-heat and no-cool responseSystem-down diagnosisRepair or temporary stabilizationPrice confirmed before the visit | Any situation where the home is not cooling in July or the heat is out on a cold night and it cannot wait for a routine appointment | We take emergency calls every day from 6:00 AM to 9:30 PM. Having the make and model of the equipment ready speeds up the phone diagnosis before the visit is scheduled. |
