We've served this area long enough to know what works, and we know that a Texas summer does not wait for a convenient time to break down your AC. The calls we get range from urgent no-cool emergencies in the middle of August to annual tune-ups before the season changes, from a thermostat that stopped responding to a full system replacement that has been put off one season too long. We handle all of it, for homeowners, property managers, and business owners across New Braunfels and the surrounding communities.
The Texas Hill Country brings long, punishing summers and winters that are mild but real enough to matter when your furnace stops working at midnight. We stay available for both. When something goes wrong outside of regular business hours, same-day and emergency scheduling options are part of how we work. We show up with the right tools, give you a clear picture of what is going on, and tell you what the repair or replacement will cost before any work begins. No pressure and no gimmicks, just reliable comfort.
We're one phone call from getting your comfort right.
Heating and cooling a home right takes the right tools and a trained hand, and nowhere is that truer than in Central Texas, where an air conditioner works harder and longer than almost anywhere else in the country. AC repair and service make up the largest share of what we do, and our technicians have seen every symptom a central air system can throw at them.
When your air conditioner is blowing warm air, making noise it should not be making, freezing up, leaking water, or simply refusing to start, we come out, run a full diagnosis, and tell you exactly what is wrong. A repair visit may involve checking refrigerant levels and diagnosing leaks, testing the condenser and compressor, inspecting electrical connections at the unit, and confirming that the system is cooling the way it should before we leave. We make the repair and leave the home tidy.
When a system is past the point of repair, or when the repair cost no longer makes sense against the age of the equipment, we walk you through replacement options clearly and honestly. We install central air systems as well as ductless mini-split systems for homes or spaces where traditional ductwork is not practical. Every installation is handled by qualified HVAC technicians and meets code-compliant HVAC work on every job.
From a quick tune-up to a whole-system replacement, we've seen it all, and that includes the heating calls that come in during a cold snap when nobody expected it. New Braunfels winters are mild by most measures, but a furnace that will not start or a heat pump stuck in the wrong mode is a real problem that deserves a fast response.
Common furnace calls include no heat at all, cold air blowing from the vents, unusual sounds during operation, and systems that cycle on and off without reaching temperature. We diagnose the problem, explain what we find, and give you a clear repair or replacement recommendation based on the age and condition of the equipment. When replacement makes more sense, we handle the full removal and installation so you are not left without heat longer than necessary.
Heat pumps are a practical fit for this climate because they handle both heating and cooling in a single system, which suits the relatively mild Texas winters well. If your heat pump is not heating or cooling properly, is running constantly, or has stopped responding to the thermostat, we diagnose and repair the issue. We also install new heat pump systems for homeowners who are replacing aging equipment or making the switch from a separate furnace and AC setup.
We'll diagnose it, fix it, and test it before we leave.
We built this business around HVAC work like this. A full system replacement or new installation is one of the bigger decisions a homeowner or property manager makes, and we take that seriously. The process starts with a thorough assessment of the existing setup, the size of the space, and what the customer actually needs. From there, we walk through equipment options, give a clear and complete quote before work begins, remove the old equipment, install the new system, and test everything before we consider the job done.
Work on every replacement and installation is performed by qualified HVAC technicians who know what correct installation looks like and why it matters for long-term system performance. We also handle thermostat and smart-control installation as part of a complete system setup, so your new equipment is paired with controls that make sense for how you use your home or building. Pricing is explained upfront. There are no surprise fees added after the fact.
Let us handle the install and the permits.
Leaking or damaged ductwork is one of the most common reasons a system that works fine on paper fails to keep a home comfortable. Air that escapes into unconditioned spaces means the equipment runs longer, works harder, and still does not deliver what it should to the rooms that need it. We inspect duct systems, locate leaks and damage, and seal or repair them so the airflow reaches where it belongs.
Central Texas summers bring heat and humidity together, and that combination affects the air inside the home as much as the temperature. We install air filtration systems and whole-home dehumidifiers to address both the quality and the comfort of indoor air, which matters especially for households with allergy concerns or anyone who notices the air feeling heavy during the humid months.
Seasonal tune-ups are the straightforward way to avoid emergency calls. A spring check before the AC season and a fall check before heating season catch small problems before they become expensive ones. Annual maintenance visits keep equipment running efficiently and extend the useful life of the system. The kind of HVAC work neighbors pass along by word of mouth is often the quiet, preventive kind that keeps a home running without drama.
We've served this area long enough to know what works for commercial properties too. Offices, retail spaces, restaurants, warehouses, and multi-unit properties across New Braunfels and Comal County all have heating and cooling needs that demand a contractor who responds quickly and works without disrupting the business. We handle commercial AC repair and service, rooftop unit repair and maintenance, heating system service, and full system replacement for commercial buildings. The same values apply: fast response, honest pricing, and qualified technicians on the job.

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.
