Summer in San Antonio doesn’t mess around. When your old unit gives out in July and the indoor temperature climbs past 85 before noon, you need more than a vague promise that someone will show up “sometime between 12 and 4.” You need a company that tells you who’s coming, when they’ll arrive, and exactly what the job costs before they touch a single tool. That’s how Halden Heating and Air San Antonio has operated since 2004, and it’s why homeowners across Alamo Heights, Helotes, and Kirby call us when they need a new system installed right. Andre Fuller leads our team here in San Antonio, and every job starts the same way: a written price, a live arrival time you can track on your phone, and a 365-Day Done Right Promise in writing. Need help now? Call (903) 623-6784 and talk to a real person, not a voicemail tree.
Furnace Installation
Furnace Installation means replacing your old gas or electric heating unit with a new, correctly sized system that actually keeps your San Antonio home warm on those 30-degree January nights. You’d be surprised how many furnaces in this area are oversized or undersized because someone guessed instead of measuring. Halden Heating and Air San Antonio handles everything from load calculation to final inspection, and a typical furnace installation in San Antonio runs $150 to $700, though if you’re also considering AC Installation pricing, depending on the unit size, efficiency rating, and whether any ductwork modifications are needed. You get a written price before work starts, no exceptions.
Sizing Done Right
A furnace that’s too big short-cycles and wastes gas. One that’s too small runs constantly and never hits your set temperature. We measure the square footage, check the insulation, and calculate the actual heating load before recommending anything.
Duct Compatibility
Older homes in Terrell Hills and Castle Hills often have ductwork that was sized for a different era. We inspect what’s there and tell you honestly whether your ducts will work with the new unit or need attention.
Styles & brands we work with
HVAC Installation
HVAC Installation covers the full system: heating, cooling, and the air handler that moves conditioned air through your house. When both your furnace and AC are past their prime, replacing them together often costs less than doing them separately and eliminates the risk of pairing a new unit with a dying one. Halden Heating and Air San Antonio installs complete HVAC systems for San Antonio homes, with pricing that reflects the scope of work, not a salesman’s mood. Expect a complete HVAC installation to fall within the $3500 to $7500 range depending on system size, efficiency, and access.
Why Full-System Replacement Makes Sense
When your AC and furnace were installed the same decade, they’ve been aging together. Replacing both at once means one install crew, one warranty start date, and a matched system that was designed to work together.
What Halden Does Differently
We book you online, send a background-checked tech with a live arrival time, and hand you a written price before any work begins. You track your technician to the door like a rideshare driver. No phone tag, no four-hour windows.
Heat Pump Installation
Heat Pump Installation is a smart option in San Antonio’s mild winters because a heat pump both cools and heats by moving heat rather than burning fuel. It’s one unit that handles the whole year, which simplifies maintenance and can cut your winter heating costs compared to running straight resistance heat. Halden Heating and Air San Antonio installs heat pumps sized for your home’s actual load, and you’ll see the same upfront written pricing we apply to every job. A heat pump installation in San Antonio typically runs from $3500 to $7500 based on capacity, brand, and whether you’re upgrading your electrical panel.
Is a Heat Pump Right for Your Home?
Homes in Fair Oaks Ranch and Scenic Oaks that run on electric heat are ideal candidates. A heat pump delivers about three units of heat for every unit of electricity it pulls, which shows up as real savings on your winter bill.
Cold-Weather Performance
Modern heat pumps handle San Antonio’s rare freezes far better than older models. We match you with a unit rated for our climate and walk you through how the backup heat works so there are no surprises on a 25-degree morning.
Ductless Mini Split Installation
Ductless Mini Split Installation puts heating and cooling exactly where you need it without running ducts through walls or attics. It’s the go-to solution for garages, additions, sunrooms, and older homes in Castle Hills or Alamo Heights where the original floor plan never included central air. Halden Heating and Air San Antonio handles the full install: mounting the indoor air handler, connecting the refrigerant lines, and setting up the outdoor condenser. A ductless mini split install in San Antonio generally costs $3500 to $7500 depending on how many zones you need and the brand you choose.
Zoned Comfort Without Ducts
Each indoor unit has its own thermostat, so you can cool the bedroom to 70 while the living room stays at 75. That kind of control is hard to get with a central system without expensive zoning panels.
Fast, Minimal-Disruption Install
Most single-zone mini splits install in one day. We drill a small hole for the line set, mount the bracket, and connect everything outside. The hardest part of your day is deciding where the remote lives.
AC Replacement
AC Replacement means pulling out your worn-down condenser and evaporator coil and installing a properly matched new system that won’t die on the hottest Saturday of the year. If your current unit is over 12 years old, needs a refrigerant that’s being phased out, or has already had multiple repairs in the last two seasons, replacement usually beats repair. Halden Heating and Air San Antonio handles AC replacement for homes across San Antonio, and you’ll know the full price before we order a single part. Expect AC replacement in this market to run from $3500 to $7500 depending on SEER rating (that’s the efficiency score), system size, and access to your existing equipment.
Repair or Replace: The Honest Math
If a repair costs more than a third of what a new unit would, replacement makes more sense over the long haul. We’ll show you the numbers both ways and let you decide. We don’t earn more by pushing you into something you don’t need.
What the 365-Day Done Right Promise Means for You
After your AC replacement, you get a full year of written accountability. If anything about the install isn’t right, we come back and make it right. That’s the Relay Visibility Guarantee, and it’s included on every job.
Central Air Conditioning Installation
AC Installation in San Antonio is the standard whole-home cooling solution for most San Antonio houses. A matched outdoor condenser and indoor coil connected to your existing ductwork, sized correctly for the square footage, and installed cleanly. Halden Heating and Air San Antonio has installed central air in everything from 1,200-square-foot starter homes in Leon Valley to larger two-story builds in Timberwood Park. You’ll pay $3500 to $7500 for a typical central AC installation in San Antonio, with the final number depending on capacity, efficiency, and whether your existing line set and electrical can be reused.
The Importance of a Matched System
Pairing a new outdoor unit with an old indoor coil tanks your efficiency and can void the manufacturer warranty. We always replace both sides together so the system actually performs at the SEER rating on the box.
Refrigerant Changes That Affect Your Decision
Older systems often run on R-22, which has been phased out and is now expensive to recharge. New units use R-410A or newer refrigerants with lower environmental impact and better long-term availability. If you’re still on R-22, replacement is worth thinking about now.
Brands We Service
We work on Rheem systems every week in San Antonio, and our techs know their air handlers and heat pumps well enough to diagnose issues quickly and install them cleanly the first time. We stock common Rheem parts on the truck so repairs don’t turn into a wait-and-see situation.
York units show up often in newer construction around Fair Oaks Ranch and Timberwood Park, and we’re familiar with their condenser designs and communicating thermostat setups. Whether it’s a York, a Daikin ductless mini split, or a Bryant central system, our techs have the training and the parts to get it done. If you have one of these brands or anything else, we can help. Call (903) 623-6784 and tell us what’s on the side of the unit.

- The AC runs but won’t cool. This usually means low refrigerant or a failed compressor. Running a system low on refrigerant stresses the compressor and can turn a $200 repair into a $4000 replacement if ignored.
- Ice is forming on the copper lines outside. Ice means airflow or refrigerant problems, and it’s actively damaging the system while it builds. Shut off the unit and call us. Letting it thaw and refreeze compounds the damage.
- The breaker trips every time the AC kicks on. That’s your electrical system telling you something is drawing too much current. It could be a failing capacitor, a grounded compressor, or undersized wiring. A pro needs to diagnose it before it becomes a fire hazard.
- You hear banging, grinding, or screeching from the outdoor unit. These sounds mean a mechanical component is on its way out: a motor bearing, a compressor, or a bent fan blade. The sooner it’s caught, the less you pay.
- Your energy bills jumped without any change in usage. A system that’s lost efficiency works harder and longer to hit the same temperature. In a San Antonio summer, that can add $100 or more to a single monthly bill without you noticing until it’s been happening for months.

How Much Does AC Installation Cost in San Antonio?
A typical our AC Installation in Helotes runs $3500 to $7500, with most homeowners landing between $4500 and $6000 for a mid-range 16 SEER system with a new air handler. Smaller homes in Kirby or Lackland AFB housing with a 2-ton unit might come in at the low end, while a larger two-story in Timberwood Park or Fair Oaks Ranch with a high-efficiency 18 SEER heat pump could hit the top of that range. The main factors that move the price: system size (measured in tons), efficiency rating (SEER), brand, whether your existing ductwork and line set can be reused, and how accessible your equipment is. Each of those items should be itemized on your quote. If a company won’t break it down, that’s a red flag.
How to Avoid Overpaying in San Antonio
Get at least two quotes, and make sure each one includes the same efficiency rating and brand. A $3500 quote for a 13 SEER unit is not the same as a $6500 quote for a 20 SEER variable-speed system. We put every detail in writing so you can compare apples to apples. Our free estimate includes a full load calculation (the actual measurement of what your home needs, not a rule-of-thumb guess), a written scope of work, and an itemized price. Call (903) 623-6784 and we’ll schedule it around your life, not the other way around.

Frequently Asked Questions About AC Installation in San Antonio
AC Installation in Universal City means removing your old cooling equipment and putting in a fully matched new system: outdoor condenser, indoor evaporator coil, and often a new air handler or furnace if you’re replacing the whole setup. It includes load calculation, refrigerant charging, electrical connections, and a final system test. At Halden Heating and Air San Antonio, every install ends with a written guarantee and before-and-after photos.
Most standard AC installations take one full day, roughly 6 to 8 hours depending on access, system size, and whether ductwork modifications are needed.

Clear a path to the indoor unit and the outdoor condenser, and make sure your electrical panel is accessible. Move any cars out of the driveway if the condenser is in the garage or near the drive. That’s really it; we handle the rest, including hauling away the old unit.
