New Braunfels sits in the heart of South-Central Texas, where long, hot, humid summers push cooling equipment hard and mild but genuine winters still call for reliable heat. The services below are the ones that come up most often here, and we have built real expertise around each of them.
Aging HVAC equipment takes a beating in this climate. Long cooling seasons, persistent heat, and high humidity all accelerate wear on compressors, heat exchangers, and air handlers. When a system reaches the end of its useful life, a full replacement is often the more practical and cost-effective path. We handle the whole job: equipment selection sized for your space, removal of the old unit, installation of the new system, refrigerant handling, and airflow testing before we leave. Newer equipment also delivers meaningful energy-efficiency gains, which adds up fast when a system runs as many hours per year as it does here. We handle residential replacements and commercial system upgrades across Comal County. We make the repair and leave the home tidy.
Heat pumps are a natural fit for the Hill Country climate. Mild winters mean the heating load rarely pushes a heat pump past its efficient operating range, and the same equipment handles cooling in summer. That dual-season performance makes heat pump installation a growing choice for Comal County homeowners looking to simplify their system or upgrade aging equipment. Installation involves proper equipment sizing, refrigerant line sets, air handler placement, and thermostat integration to make sure the whole system communicates correctly. For homes with additions, converted spaces, or no existing ductwork, ductless mini-split systems offer the same heat pump efficiency with flexible placement and no duct runs required. Let us handle the install and the permits.
Humidity is a real problem in New Braunfels. High relative humidity makes summer heat feel significantly worse than the thermometer reads, and it puts extra strain on AC equipment that is already working hard. A portable dehumidifier handles one room; a whole-home dehumidifier integrates directly into the HVAC system and treats all the conditioned air in the house. That means consistent comfort throughout, reduced risk of mold and moisture damage, and better indoor air quality for everyone inside. We size and install whole-home dehumidification systems as part of a broader indoor air quality approach, and we do code-compliant HVAC work on every job. We'll diagnose it, fix it, and test it before we leave.
Heating and cooling a home right takes the right tools and a trained hand, and staying ahead of problems is almost always less expensive than reacting to them. We recommend a spring AC tune-up before the heat arrives and a fall furnace inspection before you need heat. Both visits include a full system check, filter review, and any adjustments needed to keep performance where it should be.
Beyond seasonal tune-ups, we handle:
Landlords, apartment managers, and rental property owners rely on us for consistent, dependable service that keeps tenants comfortable and keeps maintenance calls from piling up. We know the demands of managing multiple properties, and we work efficiently to minimize disruption.
We've built this business around HVAC work like this, and that includes the full range of residential and commercial customers across the area. For homeowners, we handle everything from a single-room comfort fix to a complete system replacement in an older home. New construction and home additions are part of our work as well, and we help builders and homeowners select and install systems that fit the space from day one.
On the commercial side, we work with small businesses, office buildings, property managers, landlords, and multi-unit residential properties. Commercial HVAC systems carry heavier demands, and we approach installation, maintenance, and repair with that in mind. Whether it is a scheduled maintenance visit or an urgent system issue affecting tenants or customers, we show up ready to work.
New Braunfels is our home base, and we serve customers throughout Comal County and the communities around it. Our service area includes Seguin, San Marcos, Canyon Lake, Wimberley, Schertz, and Cibolo, as well as Spring Branch and other nearby areas. If you are not sure whether we cover your location, call and ask. Chances are good we have already worked in your neighborhood.
A repair addresses a specific failed component, such as a capacitor, a refrigerant leak, or a faulty control board, while a replacement involves removing the entire system and installing new equipment. We recommend replacement when the cost of the repair is high relative to the age of the system, or when the equipment has a history of repeated failures.
A system that is more than 15 years old, requires frequent repairs, struggles to maintain temperature, or has seen a sharp rise in energy costs is often telling you it is near the end of its useful life. We assess the age, condition, and repair history of the equipment and give you an honest recommendation before any work begins.
Common signs include uneven temperatures between rooms, the system running constantly without reaching the set temperature, unusual noises during operation, and higher-than-normal energy bills. An undersized system will also struggle more during the long, hot summers that New Braunfels sees every year.
The winters in this part of Texas are mild enough that a heat pump operates efficiently through the heating season without the extreme cold that limits heat pump performance further north. The same system also handles cooling in summer, which makes it a practical and efficient choice for Comal County homeowners.
A whole-home dehumidifier integrates directly into your existing HVAC system and removes excess moisture from all the conditioned air in the house, not just one room. In a humid climate like South-Central Texas, controlling indoor humidity reduces the heavy, clammy feeling that persists even when the AC is running and can help protect the home from moisture-related problems over time.
A seasonal maintenance visit covers cleaning key components, inspecting electrical connections at the unit, checking refrigerant levels, testing airflow, and looking for anything that could become a failure point before the season starts. Catching a small problem in the spring is almost always less expensive than calling for an emergency repair in the middle of August.
A burning smell at the start of heating season is often dust burning off the heat exchanger and may clear on its own, but a persistent burning smell can indicate an electrical issue at the unit or a failing component that needs attention. A musty odor usually points to moisture in the ductwork or on the evaporator coil, which is worth addressing both for air quality and for the health of the system.
An AC that runs without cooling can point to a refrigerant leak, a dirty or frozen evaporator coil, a failing compressor, or airflow restrictions in the duct system. We run a full diagnosis to identify the root cause rather than guessing, because the right fix depends on what is actually wrong.
Short-cycling, where the furnace starts and stops before reaching temperature, is often caused by a dirty filter restricting airflow, an overheating heat exchanger, or a faulty flame sensor. Cold air from a furnace that is running can point to a failed igniter, a gas supply issue at the unit, or a control board problem, and each of those calls for a different repair.
When a job requires a permit, we handle that as part of the project. We perform code-compliant HVAC work on every job, and we do not leave a customer responsible for pulling their own permits on work we are doing.
Rooftop and exterior unit work is part of what we do for both residential and commercial customers. We come prepared with the equipment needed to access and service units in elevated or tight locations, and we treat those jobs with the same care as any other service call.
Yes. We provide documentation of what was found and what was done so you have a clear record of the service. That record is useful for warranty purposes, future service calls, and property management documentation.
Improperly installed equipment, undersized systems, and skipped steps on refrigerant handling or electrical connections at the unit all show up as problems down the road, often as premature failures, poor efficiency, or comfort issues that are hard to trace back to the original cause. Doing the job correctly the first time costs less over the life of the system than correcting problems that result from cutting corners.
HVAC systems lose efficiency as components wear, refrigerant levels drift, and heat exchangers accumulate buildup. A system that is working harder to deliver the same result uses more energy, and in a climate where an AC runs as many hours per year as it does in New Braunfels, that inefficiency adds up quickly on the monthly bill.

We handle the full range of heating and cooling work for homes and businesses across New Braunfels and Comal County. From a same-day AC repair in the middle of a South Texas summer to a full system replacement sized right for your home, every job gets the same honest pricing and careful workmanship. The table below lays out what each service covers and who it fits best, so you can call us knowing exactly what to expect.
| Service | What's Included | Common Needs | Good to Know |
|---|---|---|---|
| AC Repair & Service | refrigerant leak diagnosis, condenser and compressor service, evaporator coil and airflow issues | homeowners and businesses with a system that has stopped cooling or is underperforming | Same-day repair is available when the schedule allows, which matters when South Texas summer heat is not waiting around. |
| Whole-Home Dehumidification & Humidity Control | whole-home dehumidifier installation, integration with existing HVAC system, humidity assessment and system sizing | homes in the Hill Country and San Antonio corridor where high indoor humidity makes a cooled space feel clammy or contributes to air quality issues | A whole-home dehumidifier pulls excess moisture out before it puts extra load on the air handler. It is one of the more impactful comfort upgrades for this climate. |
| Indoor Air Quality & Air Filtration | whole-home air purifier installation, filtration system upgrades, air scrubber and allergen reduction solutions | households dealing with dust, allergens, or air quality concerns, especially in older or tightly sealed homes | Results are something you feel every day. Cleaner indoor air reduces allergen load and supports the long-term performance of your HVAC equipment. |
| Heat Pump Installation | new heat pump system sizing and install, ductless mini-split options for additions or garages, startup testing for both heating and cooling modes | homeowners upgrading from a traditional split system or adding climate control to a space without existing ductwork | The mild winters and long cooling season in this part of Texas make heat pumps a strong fit. The system earns its keep on the cooling side and handles heating efficiently without heavy backup demands. |
| Thermostat & Smart-Control Installation | programmable and smart thermostat install, system communication diagnosis, controls upgrade for better efficiency | anyone looking to reduce energy use or gain better day-to-day control over their system | A thermostat that communicates poorly with the system can cause short-cycling and uneven temperatures. We diagnose and replace as needed. |
| Full System Installation & Replacement | proper load sizing for the space, new equipment selection and installation, startup testing and system verification | homeowners replacing an aging or failed system, or adding HVAC to a new addition or build | Correct sizing makes a measurable difference in comfort and long-term efficiency. We size to the home, not to what was there before. |
| Heating & Furnace Repair | gas furnace diagnosis and repair, no-heat emergency calls, system cycling and airflow problems | any home or building that has lost heat or is heating unevenly during a cold snap | Heating season in Comal County is short but sharp. Getting a furnace diagnosed quickly prevents a minor issue from becoming a full failure. |
| Emergency HVAC Service | same-day no-heat and no-cool calls, after-hours availability including weekends, priority dispatch for urgent system failures | any situation where a system has gone down and waiting is not a reasonable option | We are available every day from 8:00 AM to 11:00 PM. Call and we will give you an honest arrival estimate based on what is on the schedule. |
| Ductwork Repair & Sealing | duct inspection and leak testing, sealing and repair of leaking sections, duct replacement where needed | homes with uneven room temperatures, high energy bills, or reduced airflow from supply registers | Leaking ducts can send a significant share of conditioned air into attics and wall cavities. Sealing them is one of the more cost-effective efficiency upgrades available. |
| Heat Pump Repair & Service | refrigerant and controls diagnosis, mechanical component inspection, both heating and cooling modes tested | homes already running a heat pump that is underperforming in either heating or cooling mode | Heat pumps handle both seasons, so a problem in one mode often points to a shared component. We test the full system before we leave. |
| Furnace & AC System Replacement | full replacement of furnace or AC unit, matched system sizing and selection, installation and startup to code | homes where the furnace or AC has reached the end of its useful life or is no longer keeping up with demand | New Braunfels homes run their air conditioning hard from April through October. Years of sustained use add up, and replacement is often the smarter investment once a system passes a certain age and repair cost threshold. |
| Seasonal Maintenance & Tune-Ups | full system cleaning and inspection, refrigerant check and electrical connections, airflow and component condition review | homeowners and property managers who want to avoid mid-season breakdowns and keep equipment running efficiently | Spring and fall are the natural times to schedule, catching the AC before summer and the furnace before the first cold snap of the year. |
How do I know if my AC or furnace needs to be replaced rather than repaired?
A few signs point toward replacement: the system is more than 12 to 15 years old, repair costs are approaching half the price of a new unit, or the equipment is struggling to maintain temperature even after recent service. We walk through the numbers with you honestly so you can make the call that makes financial sense for your situation.
Why has my system stopped heating or cooling even though it is running?
A system that runs but does not condition the air is usually dealing with a refrigerant issue, a dirty or frozen evaporator coil, a failing compressor, or an airflow restriction. In heating mode, a cracked heat exchanger or a failed igniter can produce the same symptom. We run a full diagnostic before recommending any repair so you know exactly what is going on.
How often should I schedule a maintenance tune-up?
Twice a year is the standard: once in spring before cooling season and once in fall before the first cold stretch. In South-Central Texas, the cooling season is long and demanding, so the spring tune-up is especially important for catching anything that could become a breakdown in July.
Transparent Upfront Pricing
We quote the repair before we start the work. You know the price before anything is touched, and there are no additional charges added after the fact.
Is HVAC installation and replacement work permitted and inspected?
Yes. We complete installations to code and handle the permit process on jobs that require it. Code-compliant work protects your home, your warranty, and your ability to sell the property later without surprises.
Why is one room in my home always hotter or colder than the rest?
Uneven temperatures usually come from one of three sources: duct leaks or restrictions sending less air to certain rooms, an undersized or improperly balanced system, or a thermostat placement issue. We inspect the ductwork and the system to find where the imbalance is coming from rather than guessing.
What does a seasonal tune-up actually cover?
We clean the system, inspect all major components, check refrigerant levels, test electrical connections, evaluate airflow, and look for anything that could become a problem before it does. The goal is to catch small issues while they are still small and confirm the system is ready to handle the season ahead.
Same-Day and Emergency Availability
For urgent no-heat and no-cool calls, we offer same-day service when the schedule allows and are available every day through 11:00 PM, including weekends.
Should I try to fix an HVAC problem myself before calling a technician?
Replacing a filter, clearing debris from around the outdoor unit, and resetting a tripped breaker are reasonable first steps. Beyond that, HVAC systems involve refrigerant, high-voltage components, and gas connections that require trained technicians. Attempting repairs on those systems without the right tools and training can make the problem worse and create safety risks.
How does your pricing work, and when will I know what I owe?
We give you a clear price before any work begins. The technician runs a full diagnostic, explains what was found, and quotes the repair before touching anything. There are no surprises when the job is done. Payment is collected at the time of service once the work is complete.
Code-Compliant Work on Every Job
Every installation and replacement we complete meets local code requirements. We handle the permit process on jobs that require it so the work is documented and protected.
Do I need to be home when the technician arrives?
For most service calls, yes. The technician needs access to the indoor air handler, the outdoor unit, and the thermostat, and we walk you through the findings before starting any repair. For rental properties, we can coordinate directly with a tenant for access and communicate findings and pricing to the property owner separately.
What do strange noises from my HVAC unit usually mean?
Banging or clanking often points to a loose or failing mechanical component. Squealing can indicate a worn belt or bearing. Clicking that does not stop is sometimes a relay or control issue. Hissing near the indoor unit can suggest a refrigerant leak. None of these should be ignored. We diagnose the source before recommending a fix.
How long does a full system replacement typically take?
Most residential replacements are completed in a single day. A straightforward swap of an existing system usually runs four to six hours. More involved jobs, such as adding ductwork or installing a new system in a space that did not have one, may take longer. We give you a realistic timeline when we schedule the installation.
