Frequently Asked Questions - HVAC in San Antonio, TX
Straight answers to the questions San Antonio homeowners ask us most. If you don't see yours here, call (903) 623-6784 and we'll talk it through.
Pricing & Cost FAQs
Most AC repairs in San Antonio run between $150 and $650 depending on the part and the system. A capacitor replacement is usually on the lower end, while a compressor or blower motor lands higher. We give you a written price before any work starts, so there's no surprise when the job is done. Our techs send photos of what they found, so you can see exactly what you're paying for. Call (903) 623-6784 and we'll get you a real number for your specific system.
A full HVAC replacement in San Antonio typically costs between $6,500 and $14,000 depending on home size, efficiency rating, and ductwork condition. That's a wide range because a 1,400-square-foot single-story in Kirby needs far less than a 3,200-square-foot two-story in Timberwood Park. We never give a ballpark over the phone and call it a quote. We come out, size the system properly using a load calculation, and hand you a fixed written price. Call (903) 623-6784 for an assessment.
An AC tune-up in San Antonio generally runs $89 to $189 depending on what's included and the time of year. At Halden Heating and Air San Antonio, our maintenance visit includes a full system check, coil cleaning, refrigerant level verification, and a written report of what we found. Techs aren't paid on what they sell, so the report is what it is: facts about your system. Pre-season tune-ups in March and April tend to book fast in this market. Call (903) 623-6784 to lock in a visit.
San Antonio's cooling season runs longer than most Texas cities, which means systems here accumulate wear faster and need more service over their lifespan. Humidity from the gulf also stresses coils and condensate lines harder than drier markets like El Paso. Parts availability in San Antonio is good, but labor rates reflect the cost of living here. We keep pricing transparent with a written quote before anything starts, so you always know the number. Our goal is fair pricing with zero ambiguity.
We price by the job, not the hour. Before any work begins, you get a written price that covers the entire repair or installation. That price doesn't change based on how long the tech is on site. The way Andre Fuller runs our San Antonio team, you should never be watching the clock wondering what the final bill will be. You approve the number first, then we start. It keeps the whole process simple and removes the worst part of hiring a trade.
Yes, financing is available through the Relay Home Co. network for qualifying homeowners. A new system is a big purchase, and spreading it out makes sense for a lot of families in San Antonio. We'll walk you through the options, the interest rates, and the monthly payment before you commit to anything. The price you're quoted is the price you finance, nothing hidden in the paperwork. Call (903) 623-6784 and we'll explain what's available for your situation.
Service & Process FAQs
You book online or by phone, then track your tech to the door with a live arrival time. No four-hour windows. When the tech arrives in San Antonio, they diagnose the issue, take photos of what they find, and put the repair price in writing before any work starts. Once the job is done, you get before-and-after photos and a digital invoice you can pay from the link. The whole process is built around visibility, so you always know who's coming, when, and what it costs.
Most common AC repairs take between 1 and 3 hours once the tech is on site and the part is on the truck. Jobs that require a part we have to order can take a day or two longer. In San Antonio's summer heat, we know waiting on a part is brutal, so we stock the most common capacitors, contactors, and thermostats on our trucks. We'll always tell you the timeline before we order anything. Call (903) 623-6784 and describe your issue and we'll tell you what to expect.
A complete system replacement in San Antonio usually takes one full day, sometimes stretching into a second day if ductwork modifications are needed. We schedule a firm install date and show up at the time we give you. The crew handles the removal, the new equipment, the electrical, and the refrigerant. After the install, the tech walks you through the thermostat and covers what changed. We don't leave until the system is running and verified. You get a written price before install day so the number is already settled.
Yes, for the first visit we ask that someone 18 or older be home to give us access and make decisions. After we've worked with you once, we can arrange future maintenance visits with remote access if you have a smart lock or garage code, but that's a conversation between you and your tech. The live arrival tracking makes it easy to coordinate if you need to step out and come back. Most of our San Antonio customers just watch the tech's progress from the app.
Yes. Every job finishes with a digital invoice texted to your phone, and you can pay it right from the link. No paper, no chasing down a bookkeeper, no mailing a check. The invoice shows exactly what was done and the price you were quoted before the work started. Andre Fuller and the San Antonio team built our process around this because it matches how people actually live now. You get a record on your phone, and your warranty info is attached to the same thread.
We serve San Antonio proper and the surrounding communities including Universal City, Timberwood Park, Leon Valley, Helotes, Fair Oaks Ranch, Scenic Oaks, Castle Hills, Alamo Heights, Terrell Hills, and Kirby. We also serve homes near Lackland AFB. If you're just outside those areas, call us anyway and we'll let you know if we can make it work. Our techs are local and know the neighborhoods, the home styles, and the common system issues in each one. Call (903) 623-6784 to verify coverage for your address.
Brands & Parts FAQs
We install and service Rheem, York, and Daikin equipment. Each brand has strong models for specific situations: Rheem makes dependable mid-range systems that work well in San Antonio's climate; Daikin offers excellent high-efficiency options; York has solid budget-conscious lines that still deliver. We'll recommend a specific model based on your home's size, your budget, and how long you plan to stay in the house. The brand matters less than the sizing and the install quality, honestly.
The brand matters less than most people think. What matters more is correct sizing, quality installation, and regular maintenance. A properly installed mid-range Rheem will outperform a poorly installed top-tier Daikin every time. In San Antonio, the real enemy is undersized equipment and sloppy ductwork, not brand choice. We carry Rheem, York, and Daikin because they've proven durable in our hot, humid climate and have strong parts availability in this region. We'll tell you when the premium brand is worth it and when it isn't.
San Antonio HVAC systems typically last 10 to 14 years, which is shorter than the 15 to 20 years you might see in cooler climates. The extended cooling season here means your system runs more hours per year. Humidity accelerates coil corrosion, and the hard water in many parts of San Antonio can shorten the life of evaporator coils. Alamo Heights homes with older systems often surprise homeowners with how quickly issues compound. Regular maintenance extends that lifespan, but eventually replacement becomes the smarter financial call.
We can service Bryant systems already in your home, and we'll source Bryant parts when needed. For new installations, we primarily recommend Rheem, York, and Daikin because our techs have deep experience with those lines and we have strong parts access in San Antonio. If you're set on Bryant, call (903) 623-6784 and we'll talk through what's possible. Our job is to give you honest guidance, not push you into a box that doesn't fit.
Licensing & Insurance FAQs
Every pro working under the Halden Heating and Air name is required to hold the license and insurance their state requires. That's a Relay Standard, not a suggestion. Texas requires HVAC contractors to be licensed through TDLR, and we operate within that framework. We're also insured and bonded through the Relay Home Co. standard. When a tech arrives at your San Antonio home, ask to see their credentials. We'll never be offended by that question. It's the right thing to check.
The people who show up at your door in San Antonio work under the Halden Heating and Air name and answer to Andre Fuller's standards. You'll know exactly who is coming before they arrive through the tracking link, with their name and photo. The core promise doesn't change: a written price before work starts, photo updates of what's happening, and a digital record of everything. You don't need to wonder who's on your property or what they're doing. We built the system to eliminate that stress.
In Texas, an HVAC technician needs a TDLR-issued registration and, for refrigerant handling, an EPA Section 608 certification. When you hire any company in San Antonio, you should verify both. That's the baseline for legally working on residential AC systems here. We require our techs to meet every state and federal requirement before they step foot on a job. If you're comparing companies, ask about TDLR and EPA certs directly. A legit shop answers without hesitation.
Emergency & Response FAQs
We understand that an AC failure in San Antonio summer is a genuine emergency, especially in neighborhoods like Leon Valley or Scenic Oaks where afternoon temperatures climb fast. Our regular hours are Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM. When you call during those hours, a coordinator answers and connects you with our local team so we can get a tech dispatched as quickly as possible. Call (903) 623-6784 and we'll get you scheduled.
We do everything we can to get a tech out the same day when you call during our regular hours, which are Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM. San Antonio heat waits for no one, and neither do we. The fastest path is to call (903) 623-6784, tell us what's happening, and we'll tell you honestly when the next available tech can be there. You'll get a live arrival time you can track on your phone, not a vague window.
Our San Antonio location is closed on Saturdays. If your AC fails on a Saturday, the safest move is to close your blinds, run ceiling fans, and avoid using the oven or dryer during the hottest part of the day. If you have a portable or window unit, now's the time to use it. Call us Sunday morning at 7:00 AM when we open and we'll get you on the schedule. Staying hydrated and cooling your core body temperature matters more than the house in extreme heat. If you have elderly family or young children in the home, consider a hotel for the night if indoor temperatures climb into the 90s.
A frozen AC in 100-degree heat usually means low refrigerant or restricted airflow. The coil gets too cold, condensation freezes on it, and the system can't do its job. Dirty filters, closed vents, or a failing blower motor can all trigger it. If you see ice on the indoor coil or the copper line outside, turn the system off and let it thaw while you wait for a tech. Running it frozen can kill the compressor, turning a $200 fix into a $3,000 replacement. Call (903) 623-6784 and we'll diagnose it properly.
Warranty & Guarantees FAQs
The Relay Visibility Guarantee is the promise every Relay company works to: total visibility. You get a live arrival time you can track to your door, photo updates of the work before and after, and a written price before anything starts. You always know who is coming, when they'll be there, and what it will cost. That guarantee covers every job we do in San Antonio, from a thermostat swap to a full system replacement. It's not a tagline. It's how we operate.
Our workmanship is covered by the Relay Visibility Guarantee, and equipment installations carry manufacturer warranties from Rheem, York, or Daikin depending on what you choose. Manufacturer coverage varies by brand and model, so we'll walk you through exactly what's covered and for how long before you sign anything. The installation quality is on us, and we stand behind the work. If something isn't right, call (903) 623-6784 and we'll make it right.
Most manufacturer warranties require annual maintenance to stay valid. If you skip tune-ups for three years and the compressor fails, the manufacturer can deny the claim. In San Antonio's heat, missing maintenance is especially risky because systems here run harder than anywhere else in Texas. Keep records of every visit and you'll be protected. We send digital invoices and photo reports after every tune-up, so you always have the documentation your warranty needs. Book once a year and you're covered.
If the repair costs more than a third of a new system's price and your unit is over 10 years old, replacement usually makes more sense. In San Antonio, where systems age fast, we often see 12-year-old units with $900 repairs that only buy another season. If your unit has a refrigerant leak from a coil, replacement is almost always the better long-term play. Andre Fuller's rule for San Antonio homeowners: if the math is close, lean replacement. Call (903) 623-6784 and we'll give you honest numbers for both paths.
Some things are safe to check on your own: dirty filters, tripped breakers, blocked condensate lines, closed vents. But anything involving refrigerant, capacitors, or electrical wiring should be left to a trained professional. Capacitors hold a charge that can hurt you even when the power is off. Refrigerant is regulated by the EPA and leaks are bad for the environment. Getting these things wrong turns a small problem into an expensive one. If you've checked the simple stuff and the system still isn't cooling, call (903) 623-6784 and we'll take it from there.
