When a central air system stops cooling in the middle of a South Texas summer, that call comes in fast. In a town the size of Terrell Hills, with a housing stock that leans toward established homes rather than new construction, the most common scenario is equipment that has been running hard for years and finally hits a wall. A capacitor fails, a refrigerant charge drops, a blower motor gives out, and the house stops cooling before the homeowner realizes anything was wrong. That is the call we get most often, and it is where we start.
We handle the full range of heating and cooling work for Terrell Hills properties, from a single repair on an aging system to a complete replacement when the math stops making sense. Rental property owners, businesses that cannot afford downtime, and households trying to figure out whether to fix or replace are all part of the picture.
Call (830) 632-8965 for a quote.
The visit starts with a conversation, not a parts list. When the technician arrives, the first thing that happens is a look at what the system is actually doing, not what it sounds like from a description on the phone. That means checking the equipment, testing the components most likely to produce the reported symptom, and working through the likely causes before any repair is quoted.
For a no-cool call, that typically means checking refrigerant charge, reading capacitor values, testing the compressor, and assessing airflow through the evaporator coil. For a no-heat call, the ignition system, the pressure switches, and the limit controls are all on the list. The diagnosis gets explained before anything is agreed to.
Nothing gets replaced before you know why.
Heating and cooling jobs in a town like this tend to fall into a few clear categories. The homes here are not new, the equipment in many of them reflects that, and the calls we take mirror it. Here is what comes up most often and what each job actually involves.
When an older central air system reaches the end of its useful life, the replacement is not simply a swap. A proper installation starts with sizing the new equipment to the actual load in the home, which accounts for square footage, ceiling height, window exposure, and how the duct system is configured. A system that is too large short-cycles and leaves the air humid. One that is too small runs constantly without reaching temperature. Getting it right at installation is what makes the equipment perform the way it should through years of South Texas summers.
Heat pump adoption has grown steadily across this part of Texas, and for good reason. A heat pump handles both heating and cooling from a single outdoor unit, which is a practical fit for a region where winters are mild enough that a gas furnace is rarely pushed to its limits. Installation involves refrigerant line sizing, outdoor unit placement, air handler integration, and thermostat setup. We also handle replacement when an existing heat pump is losing efficiency or no longer switching correctly between modes.
The evaporator coil sits inside the air handler and does the actual work of pulling heat out of the air. When it gets coated in dust and debris, airflow drops, cooling capacity drops with it, and the system starts running longer to hit the same temperature. A coil that has been neglected long enough can freeze over entirely. Cleaning restores airflow and efficiency. If the coil itself is damaged or leaking refrigerant, repair or replacement is the conversation, and the diagnostic will make clear which one applies.
Older homes in Terrell Hills sometimes have additions or converted spaces that the original duct system never properly reached. A mini-split handles those situations without the cost and disruption of extending ductwork. Each indoor unit conditions the space it serves independently, which also allows for zone control in homes where different rooms have different heating and cooling needs. Installation involves mounting the indoor unit, running refrigerant lines to the outdoor unit, and setting up the controls.
Humidity is a real factor in this part of Texas through the warmer months. A standard air conditioner removes some moisture as a byproduct of cooling, but it is not designed to hold indoor humidity to a specific target. A whole-home dehumidifier integrates with the existing HVAC system and manages moisture independently, which means the AC can run at a cycle length suited to temperature control rather than being pressed into service as a dehumidifier. Airflow balanced rather than left to chance means the installation is set up to work with the system, not against it.
A furnace that is blowing cold air, short-cycling, or not turning on at all has a specific cause, and the diagnostic works through the most likely ones before any part is quoted. Ignition faults, failed pressure switches, tripped limit controls, and cracked heat exchangers are all on the list. In a climate where the heating season is short but the nights can get genuinely cold when a front moves through, a furnace that is running rough in October is worth looking at before January arrives.
The price conversation happens on the call, before the visit is scheduled. 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 put on the schedule.
What moves a quote is the fault itself, what has to be accessed to reach it, and whether the answer is a repair or a replacement. A capacitor replacement and a full system installation are different scopes, and the call reflects that. Pricing set out up front. Code-compliant work. Straight explanations.
If the diagnostic turns up something beyond what was discussed on the phone, that gets explained before any additional work is done. Nothing moves forward without your agreement.
Commercial properties and rental units in Terrell Hills face a different kind of pressure than a single-family home. A tenant who has no cooling in August cannot wait a week, and a business that needs its space conditioned to stay open cannot absorb a multi-day outage.
For properties that have to stay operational, we work through the scope on the call and confirm what the visit covers before anything is scheduled. If a repair can be staged to keep the system running while a part is sourced or a replacement is arranged, that gets discussed. The goal is to keep the property functional while the work gets done, not to schedule around our convenience at the expense of yours.
Thermostat and smart-control installation is part of the commercial picture too. A programmable or connected control system can reduce runtime during off-hours and give a property manager visibility into what the equipment is doing without requiring a site visit every time something looks off. Plenty of Terrell Hills jobs start with a look at our page of HVAC services.
We are available every day from 6:00 AM to 9:30 PM, including weekends, for both routine appointments and emergency no-heat and no-cool calls. When the system is completely down and the property is occupied, that moves to the front of the conversation.
When you call about an emergency, we scope the job on the phone first. The make and model of the equipment, whether the system is running but not conditioning the air or not turning on at all, and how long the problem has been happening all help narrow the diagnostic before the visit starts. Short-notice work is something we take on regularly. We do not quote arrival windows, but emergency calls are treated as such.
For routine appointments, seasonal tune-ups, and planned replacements, scheduling works the same way: scope on the call, price confirmed, visit booked. No pressure and no gimmicks, just straight HVAC answers.

We cover Terrell Hills and the surrounding communities across Bexar County. That includes Alamo Heights, Olmos Park, Kirby, and Windcrest, as well as San Antonio and the broader area around it. If your property is in or near Terrell Hills and you are not sure whether it falls within the service area, the call will confirm it quickly.
Yes. We scope the job on the call and confirm what the visit covers before scheduling, which includes working around an occupied unit. If the repair can be staged to keep the system running while a part is sourced, that gets discussed on the call. The goal is to keep the property habitable while the work gets done.
We take on light commercial HVAC repair, replacement, and installation across the area, including small office buildings, retail spaces, and multi-unit properties. The process is the same as a residential call: scope the job on the phone, confirm the price, then schedule. For businesses that cannot close during the work, we talk through staging and timing on the call before anything is booked.
If the system is completely out and the indoor temperature is becoming a health or safety concern, that is an emergency call. That includes a home with no cooling during a heat event, a property with vulnerable occupants and no heat, or a commercial space where the temperature is affecting people or equipment. Call us and describe the situation.
It is a significant factor. A correctly sized system, properly charged with refrigerant, with airflow balanced and controls calibrated, runs at the efficiency it was designed for and puts less stress on its components. A system that was rushed or improperly commissioned may run, but it will work harder and wear faster than one that was set up correctly.
Established homes in Terrell Hills tend to run older equipment, and the calls reflect that. Capacitor failures, refrigerant leaks at aging coil connections, blower motors drawing high amperage, and duct systems that have never been properly sealed are among the most common findings. The diagnostic works through the likely causes before any repair is quoted, so you know what you are dealing with before anything is agreed to.
Call (830) 632-8965 and we will ask about the equipment, what it is doing, and when the problem started.
By the end of the call, you will know what the visit covers and what it costs before anything is scheduled. We are available every day from 6:00 AM to 9:30 PM. Reach out to New Braunfels HVAC Company and get the conversation started.
