Plain questions. Honest diagnosis. Clear options.
For residential and commercial HVAC work alike, the scope of the job shapes everything. A homeowner dealing with uneven temperatures needs something different from a property manager keeping a rental habitable, and a light commercial building has different demands again. We work across all of it.
The everyday services cover AC repair and service, heating and furnace repair, heat pump repair and installation, full system installation and replacement, thermostat and smart-control installation, ductwork repair and sealing, indoor air quality and air filtration, and seasonal maintenance and tune-ups. Mini-split and ductless systems are part of that range on both the installation and repair side, which matters in Comal County where room additions and detached structures often need cooling without a duct run.
Property managers and landlords count on fast turnaround when a unit goes down. We handle rental property HVAC repair and light commercial service with the same process as a standard residential call: scope the job on the phone, confirm the price, then schedule. No pressure and no gimmicks, just straight HVAC answers.
Leave the heating and cooling to us.
Here's what most people get wrong about their HVAC system: a symptom and a cause are not the same thing, and misreading one leads to parts being quoted before the system is actually checked.
When the AC is blowing warm air or not cooling the house down, the cause could be a low refrigerant charge, a dirty evaporator coil, a failing compressor, or an airflow restriction. When the furnace is blowing cold air, it could be an ignition issue, a pressure switch, or something as simple as a tripped limit. When the system is not turning on at all, the thermostat, the control board, and the blower circuit all get checked before anything else is assumed.
Other common calls: AC keeps shutting off before the house reaches temperature, air conditioner making a grinding or rattling noise, condenser unit running but not producing cold air, blower fan not moving air at all, or heat pump not switching between heating and cooling modes. Each one has a short list of likely causes, and the technician who arrives works through that list rather than defaulting to the most expensive fix first.
Uneven temperatures from room to room usually point to an airflow problem, a duct leak, or a system that is not sized correctly for the load. The age of the system changes the answer, and that gets said. A fifteen-year-old air handler with a failing blower motor is a different conversation than a five-year-old unit with a refrigerant leak.
We'll find the fault and set it right.
New Braunfels sits in a climate that asks a lot of HVAC equipment. Summers are long and hot, humidity climbs through spring and fall, and winters are mild but not absent. That combination means the AC works hard for months at a stretch, humidity management matters even when the temperature is manageable, and the heating system still needs to be ready when a cold front moves through. The three services below come up constantly here for exactly those reasons.
When a system spends more on repairs in a season than it would cost to replace, the math shifts. Long cooling seasons in south-central Texas put heavy hours on AC equipment, and a condenser that has run hard through a decade of Texas summers may be at that point. Replacement covers the full matched system: outdoor condenser, air handler, coil, and the connections between them. Replacing components from the same equipment generation keeps efficiency ratings accurate and avoids the compatibility problems that come from mixing old and new.
The scope and the price are confirmed on the call before anything is scheduled. Airflow balanced rather than left to chance means the replacement is sized and set up for the actual load in the space, not just swapped in at the same nominal tonnage as the old unit.
South-central Texas mild winters make heat pumps a practical fit. A heat pump handles both cooling and heating from a single outdoor unit, which removes the need for a separate furnace in many applications. That dual function is why heat pump adoption has grown steadily across this part of Texas, where winter temperatures rarely demand the output a gas furnace is built for.
Installation involves sizing the unit for the space, placing the outdoor unit with clearance for airflow, running refrigerant line sets, and connecting to the air handler. We also handle heat pump repair and service when an existing unit is not switching modes correctly, losing efficiency, or running but not conditioning the air. The quote for installation or replacement is provided on the call.
High humidity in Comal County creates problems that temperature control alone cannot solve. When indoor relative humidity stays elevated, the air feels heavier than the thermostat reading suggests, and conditions that encourage mold growth develop in wall cavities, attic spaces, and around the air handler.
A standard air conditioner removes some moisture as a byproduct of cooling, but it is not designed to hold humidity to a specific target. A whole-home dehumidifier integrates with the existing HVAC system and handles humidity independently, which means the AC can run at a cycle length that makes sense for temperature without leaving the air damp. For allergy sufferers and anyone dealing with musty air despite a working AC, this is often the missing piece. It connects to the indoor air quality side of the system and can be combined with air filtration for a more complete approach to what the air in the home actually contains.
When the technician arrives, the real work begins, but the call before that visit matters too. When the house is not cooling down in July, or the heat is out on a night that drops into the thirties, knowing what to tell us on the phone speeds up the diagnosis. The make and model of the equipment, when the problem started, and whether the system is running at all but not conditioning the air versus not turning on at all are all useful. We can scope the job and confirm the price before the visit is scheduled.
We take emergency calls every day from 6:00 AM to 9:30 PM for no-heat and no-cool situations, systems that have stopped turning on, and anything else that cannot wait for a routine appointment. We do not quote arrival windows, but emergency work is prioritized.
Pricing set out up front. Code-compliant work. Straight explanations.
Call (830) 632-8965.
Booking an HVAC service call is simple, and the price is part of the first conversation. When you call, we go through what the system is doing, what equipment is involved, and what the visit will cover. The rate is confirmed before anything is scheduled.
Cost questions we hear regularly: what does AC repair cost, what does furnace repair run, how much is a heat pump replacement, what does a new HVAC system cost, what does duct sealing cost, what is the charge for a thermostat installation, and what does refrigerant cost to add. Each of those has a real answer that depends on the equipment, the scope, and what the diagnostic turns up. We give that answer on the call rather than after the visit.
What the call covers: the scope of the job, what the visit includes, and the rate before anything is put on the schedule. Ask what it covers and you get a straight answer.

We serve New Braunfels and the communities around it across Comal County and the surrounding region. That includes San Marcos, Seguin, Kyle, Buda, Schertz, Cibolo, Canyon Lake, and Wimberley. Calls about this area are answered by someone who knows the local equipment and can scope the job on the phone before anything is scheduled.
At the outdoor unit, the technician checks refrigerant charge, inspects the compressor and condenser coil, tests capacitor readings, and looks for signs of refrigerant leaks or physical damage. Airflow across the condenser coil is also assessed, since restricted airflow is one of the more common causes of reduced cooling capacity. For a heat pump, the reversing valve and defrost cycle operation are checked as well.
Spring is the right window for a cooling system tune-up before the long Texas summer begins. Getting the system checked in April or May means any problems surface when the weather still allows for a scheduled repair. A heating tune-up is best scheduled in early fall, before the first cold front arrives and demand for service picks up.
A banging sound often points to a loose or broken component inside the air handler or blower assembly. Squealing typically indicates a belt or bearing issue in the blower motor. Rattling can mean debris in the system or a loose panel, though it can also signal early compressor trouble. Each of these warrants a diagnostic before the system is run further.
The diagnostic starts with what the system is doing and what it was doing before the problem appeared. From there, the technician checks the components most likely to produce that symptom: refrigerant charge, blower performance, electrical connections at the unit, thermostat response, and airflow through the system. The cause is confirmed before any repair is quoted.
A furnace blowing cold air often traces to an ignition fault, a tripped high-limit switch, or a pressure switch that is not closing correctly. Short cycling, where the furnace turns on and off repeatedly without completing a full heating cycle, can indicate an overheating issue caused by restricted airflow, a dirty filter, or a failing component. Both symptoms need a proper diagnostic before any part is replaced.
An AC that requires refrigerant more than once in a season, runs constantly without reaching the set temperature, produces noticeably less airflow than it used to, or has a compressor that is drawing high amperage is showing signs of significant wear. In a south-central Texas climate where the cooling season is long, equipment accumulates hours faster than in cooler regions. If the system is more than ten to twelve years old and showing multiple symptoms, the repair-versus-replace conversation is worth having.
When the diagnostic points to replacement, the visit covers a load calculation discussion, proper system sizing for the space, and a walkthrough of what installation involves. The replacement is sized for the actual cooling and heating load in the home, not simply matched to the nominal tonnage of the old unit. The price is confirmed before anything is scheduled.
Uneven temperatures in older homes usually trace to one of three causes: duct leaks that are losing conditioned air before it reaches certain rooms, a system that was never sized correctly for the layout, or an air handler that is not moving enough air through the supply side. The diagnostic looks at airflow at the registers, static pressure in the duct system, and equipment performance before any recommendation is made. Duct sealing and system right-sizing both come up regularly in older Comal County housing stock.
Installation covers equipment selection matched to the home's square footage and layout, placement of the outdoor unit with proper clearance for airflow, refrigerant line sizing and connection, and integration with the air handler. Thermostat setup is part of the installation, and the system is tested through both heating and cooling modes before the job is complete. We also handle ductless mini-split installation for spaces where running new ductwork is not practical.
A whole-home dehumidifier ties into the air handler and operates independently of the cooling cycle, pulling moisture out of the air across the entire house rather than one room. In a Comal County summer, indoor humidity can stay elevated even when the AC is running, because the cooling cycle is not designed to hold humidity to a specific target. The dehumidifier handles that independently, which allows the AC to run at a cycle length suited to temperature control.
We are available every day from 6:00 AM to 9:30 PM for residential and commercial HVAC service across New Braunfels and Comal County. The price is set on the call before anything is scheduled, and the diagnosis explained on every call means you understand what the job involves before work begins.

How often should an HVAC system be tuned up?
Once a year for each function the system handles. A cooling tune-up fits well in spring before the Texas summer begins, and a heating tune-up fits well in early fall before cold fronts arrive. A heat pump that handles both heating and cooling benefits from a check in both windows. Skipping a season does not guarantee a problem, but it does mean the first sign of trouble is more likely to show up on the hottest or coldest day of the year.
How do duct leaks affect energy bills and comfort?
A duct system that is losing conditioned air before it reaches the living space makes the equipment work longer to hit the set temperature. In a south-central Texas summer, that extra run time adds up quickly on the cooling bill. Rooms at the end of long duct runs tend to feel the shortage most, which is why uneven temperatures and high bills often trace back to the same cause. Sealing the leaks addresses both problems at the source.
What does a dirty filter or coil actually do to system performance?
A clogged filter restricts the airflow the system depends on to move heat in or out of the space. When airflow drops, the evaporator coil can ice over, which makes the problem worse in a cycle that ends with the system not cooling at all. A dirty condenser coil on the outdoor unit has a similar effect on the system's ability to shed heat, which raises head pressure and puts extra strain on the compressor. Both are straightforward to address and worth catching at a tune-up before they cause a bigger failure.
Diagnosis Explained on Every Call
Before any repair is quoted, we walk through what the system is doing, what the diagnostic found, and what the options are. You understand the job before anything is scheduled.
What is involved in a thermostat or smart-control upgrade?
The visit covers pulling the old thermostat, checking the existing wiring for compatibility with the new control, and installing and configuring the replacement. Smart controls require a C-wire in most cases, and older homes sometimes need a small adapter if that wire is not present. Once the thermostat is installed, we run the system through a heating and cooling cycle to confirm the control is communicating correctly with the air handler and outdoor unit. Scheduling features and remote access are set up before we leave.
What are the signs of a refrigerant or airflow problem?
A refrigerant issue usually shows up as warm air from the supply registers, ice forming on the refrigerant lines or evaporator coil, or a system that runs constantly without reaching the set temperature. An airflow problem shows up differently: weak airflow at the registers, rooms that do not cool or heat evenly, or a blower that sounds like it is working harder than usual. Both can produce similar symptoms at the thermostat, which is why the diagnostic checks refrigerant charge and airflow before assuming either one.
What does short cycling mean and what causes it?
Short cycling is when the system turns on and off repeatedly without completing a full heating or cooling cycle. It can come from an oversized system that satisfies the thermostat too quickly, a refrigerant charge that is too high or too low, a dirty filter restricting airflow and triggering the high-limit switch, or a failing component in the control circuit. Because several different causes produce the same behavior, the diagnostic looks at the full picture rather than replacing a part and hoping the cycling stops.
System Checked Before Parts Are Quoted
We do not quote parts before the system is actually checked. The diagnostic comes first, and the repair recommendation follows from what it turns up, not from the symptom alone.
Is older equipment worth repairing or does it make more sense to replace it?
The answer depends on the age of the system, what the repair costs, and whether the failure is a sign of broader wear. A capacitor on a seven-year-old unit is a straightforward repair. A compressor on a fourteen-year-old unit that has already had refrigerant added twice is a different conversation. We go through that math on the call and at the visit. The age of the system changes the answer, and that gets said rather than defaulted to whichever option costs more.
Do I need to be home when the technician comes out?
Someone needs to be at the property to provide access and to hear the findings and the options at the end of the visit. The technician walks through what was found and what the repair involves before any work is authorized, so having a decision-maker present makes the visit more efficient. If the property is a rental, the landlord or property manager and the tenant can coordinate access, but we confirm those details on the scheduling call.
Code-Compliant Work on Every Job
Every installation and repair is done to the standards the local code inspectors here enforce. That applies to equipment placement, refrigerant handling, and electrical connections at the unit.
What causes one room to be hotter or colder than the rest of the house?
Uneven temperatures usually trace to one of three places. The first is the duct system, where a leak or a disconnected section is losing conditioned air before it reaches that room. The second is airflow balance, where the supply and return setup in the home was never tuned to distribute air evenly across the layout. The third is a system that is not producing enough capacity to serve the full load, which shows up first in the rooms farthest from the air handler. The diagnostic looks at register airflow and static pressure before any recommendation is made.
How does indoor air quality equipment connect to an existing HVAC system?
Most indoor air quality equipment, including whole-home dehumidifiers and higher-grade filtration systems, integrates with the air handler rather than sitting standalone. The dehumidifier ties into the return side of the air handler and operates on its own control, independent of the cooling cycle. A filtration upgrade typically involves replacing or supplementing the existing filter housing with a media filter or an electronic air cleaner that fits the existing duct dimensions. We assess the existing setup on the call and confirm what the installation involves before scheduling.
How long does a full system replacement take?
Most residential system replacements are completed in a single day. The timeline depends on access to the air handler, whether any ductwork connections need modification to fit the new equipment, and whether the refrigerant line set can be reused or needs replacement. We go through those variables on the call when the scope is confirmed.
