That’s what our heating and cooling services in Castle Hills, TX deliver. Fast response times, first-visit repairs whenever possible, and technicians who actually diagnose the problem instead of pushing you toward a full replacement.

Your Castle Hills home deserves reliable climate control without the runaround. Most HVAC emergencies happen because of preventable issues—clogged filters, refrigerant leaks, worn contactors.

Texas Air Repair is a veteran-owned local HVAC company serving Castle Hills, TX and the greater San Antonio area for over 20 years. We’re not the flashiest name in town, and we’re fine with that. Our reputation comes from showing up when we say we will, charging what we quote, and fixing systems right the first time.
Castle Hills has a mix of mid-century ranch homes and custom estates—many with aging HVAC systems that need more than a quick patch job. We know this area. We understand how Texas heat stresses equipment, how older ductwork develops leaks, and how homeowners here expect professionalism without the upsell.
Our team includes licensed, certified technicians trained to handle residential and light commercial HVAC work. We’re available 24/7 for emergencies because AC failures don’t wait for business hours. And because we’re veteran-owned, we bring that same discipline and accountability to every service call.
You call or submit a request online. We ask a few questions about what’s happening—no cooling, strange noises, high energy bills—and schedule a time that works for you. If it’s an emergency, we prioritize getting someone out the same day.
Our technician arrives in a fully stocked service vehicle. They’ll diagnose the issue, explain what’s wrong in plain terms, and give you an upfront price before any work starts. No surprise fees. No pressure tactics. Just a clear explanation of your options—repair, replace, or maintain.
Once you approve, we handle the work efficiently. Most repairs happen during that first visit. Installations and larger projects get scheduled with clear timelines. After the job, we test everything, walk you through what we did, and make sure you’re satisfied before we leave. You also get warranty coverage on parts and labor, so if something isn’t right, we come back and make it right.

As a full-service air conditioning contractor in Castle Hills, TX, we handle installations, repairs, and maintenance for all major HVAC brands. That includes central air systems, heat pumps, furnaces, ductless mini-splits, and thermostats. We also offer indoor air quality solutions like air duct cleaning, sealing, and whole-home humidifiers or dehumidifiers.
Castle Hills homes average around 60 years old, and many still have original or outdated ductwork. That means airflow problems, uneven temperatures, and higher energy bills. We assess your entire system—not just the unit outside—to find inefficiencies that cost you money every month. Upgrading from an old 10 SEER system to a modern 16 SEER2 unit can cut your cooling costs by 25-35%, which adds up fast when summer electric bills hit $250 to $350.
We also offer preventive maintenance plans that extend system life and catch small problems before they become expensive failures. Regular tune-ups keep your HVAC running efficiently, reduce breakdowns, and protect your investment. In a climate this extreme, maintenance isn’t optional—it’s the difference between 12-15 years of reliable service and an 8-year system that quits during peak heat.
A full HVAC system replacement in Castle Hills, TX typically runs between $12,000 and $18,000, depending on the size of your home, the efficiency rating you choose, and whether ductwork needs modification. Larger homes or properties with complex layouts cost more. Higher-efficiency systems (16+ SEER2) have a higher upfront cost but lower operating expenses, which matters when your AC runs six months a year.
Emergency replacements during peak summer demand are the most expensive. If your system is over 12 years old and starting to show signs of decline—frequent repairs, rising energy bills, uneven cooling—it’s worth getting a quote before it fails completely. You’ll have more options, better pricing, and time to explore rebates or financing.
We provide upfront estimates that include equipment, labor, permits, and warranty coverage. No hidden fees. No pressure to upgrade features you don’t need. Just a clear breakdown so you can make an informed decision.
First, check your thermostat settings and make sure it’s set to cool. Verify the temperature is set lower than the current room temperature. Then check your circuit breaker—sometimes a tripped breaker is the only issue.
If those aren’t the problem, check your air filter. A clogged filter restricts airflow and can cause the system to shut down as a safety measure. If the filter is dirty, replace it and see if the system kicks back on after 10-15 minutes.
If none of that works, call us. We offer 24/7 emergency HVAC services in Castle Hills, TX because we know AC failures don’t wait for convenient times. Over 80% of summer breakdowns are preventable issues—refrigerant leaks, failed capacitors, dirty coils—that we can usually fix the same day. The faster you call, the faster you’re cool again.
You should schedule HVAC maintenance in Castle Hills, TX at least once a year—ideally twice. Get your AC serviced in early spring before cooling season, and your heating system checked in fall before winter. Texas heat is brutal on air conditioners, and regular maintenance keeps them running efficiently when you need them most.
During a maintenance visit, we inspect and clean components, check refrigerant levels, test electrical connections, lubricate moving parts, and replace filters. We also look for early warning signs—worn belts, failing capacitors, ductwork leaks—that could turn into expensive repairs if ignored.
Proper maintenance can save you $15,000 to $25,000 over 20 years by extending system life and reducing energy waste. It also prevents most emergency breakdowns, which always seem to happen on the hottest day of the year. A small investment in upkeep beats a big bill for emergency repairs or premature replacement.
Yes. Federal tax credits and utility rebates are available for high-efficiency HVAC systems in Texas. The federal government offers tax credits up to $2,000 for qualifying heat pumps and central AC units that meet specific efficiency standards. You may also qualify for rebates from your local utility company when you upgrade to an energy-efficient system.
These incentives change periodically, so it’s worth asking about current programs when you’re considering a replacement. We stay updated on available rebates and can help you understand what you qualify for based on the equipment you choose.
Upgrading to a 16 SEER2 or higher system not only makes you eligible for rebates—it also reduces your monthly cooling costs. In Castle Hills, where summer energy bills can hit $250 to $350 for efficient homes, a 25-35% reduction in cooling costs adds up quickly. The rebates and savings often offset a significant portion of the upgrade cost within a few years.
If your system is under 10 years old and the repair costs less than half the price of a new unit, repairing usually makes sense. If your system is over 12-15 years old, requires frequent repairs, or has a major component failure like a compressor or heat exchanger, replacement is often the smarter financial move.
Here’s a simple way to think about it: multiply the repair cost by the age of your system. If that number exceeds $5,000, replacement is probably the better option. For example, a $500 repair on a 12-year-old system equals $6,000—close to half the cost of a new system that will last another 12-15 years with proper maintenance.
We’ll always give you an honest assessment. If a repair buys you a few more good years, we’ll tell you. If you’re throwing money at a dying system, we’ll tell you that too. Our job is to give you the information you need to make the right call for your situation and budget.
Yes. We offer 24/7 emergency HVAC services in Castle Hills, TX because air conditioning failures don’t follow a schedule. When your system quits at 9 PM on a Saturday in July, you need help now—not Monday morning.
Our emergency service includes same-day response for urgent situations. We prioritize calls based on severity, and we do everything possible to restore your comfort quickly. Our technicians carry common parts and diagnostic tools, so many emergency repairs happen during the first visit.
We don’t inflate prices just because it’s after hours or a weekend. You get the same honest pricing and transparent service you’d receive during regular business hours. We’re available around the clock because we understand how miserable a Texas home gets without working AC, and we’re committed to getting your system back online as fast as possible.
