Get your free estimateFast, Reliable AC Installation Across Alamo Heights
AC installation in Alamo Heights typically runs $3,500 – $7,500, and the right system for your house depends on things most quick-bid companies never check: duct size, electrical panel capacity, and how your 1920s – 1950s floor plan actually moves air. We handle all of it. When you call Halden Heating and Air San Antonio at (903) 623-6784, you’ll get a written price before any work starts, a live arrival time you can track, and a tech who knows Alamo Heights homes specifically. Not a four-hour window. Not a door-step surprise.
Alamo Heights is its own animal. The mix of historic homes and newer custom builds means a one-size-fits-all AC swap fails more often than it succeeds. We address that upfront, before you spend a dollar.
Key Takeaways
- Full AC installation in Alamo Heights runs $3,500 – $7,500 depending on system size, ductwork condition, and electrical work needed.

Why Halden Heating and Air San Antonio Is Alamo Heights’s Preferred AC Installation Company
We’re part of the Relay Home Co. network, founded in 2004, and independently owned and operated. That means something specific in Alamo Heights: we’re not a franchise sending whoever’s available. Our AC Installation team works on the housing stock this city actually has. Pier-and-beam foundations with sagging duct runs. Original gravity furnace conversions with undersized sheet metal. Plaster walls that make running new lines a careful job, not a demolition project.

Styles & brands we work with






Heat Pump Installation in Alamo Heights
Heat pump installation in Alamo Heights often turns out to be the smartest replacement for an aging central air system, especially in homes that still run a gas furnace half the year. A heat pump moves heat instead of generating it, which means it cools in summer and warms in winter. For Alamo Heights homes with scorching, humid summers and mild winters, that dual function can eliminate the need for a separate furnace altogether. Installation runs $3,500 – $7,500 here depending on sizing, duct condition, and electrical work.
Why Manual J Load Calculation Matters Here
Most Alamo Heights homes built before 1960 have ductwork sized for gravity heat, not pressurized central air. That’s not a guess; it’s what we find when we open the crawlspace. A heat pump pushing 1,200 CFM through ducts designed for 700 CFM will run loud, wear out blower motors, and leave bedrooms hot. We run a Manual J load calculation on every install. It tells us exactly how much heating and cooling your specific house needs, room by room. Then we match the equipment to that number, not to the brand the last contractor had in stock.
Humidity Control in Alamo Heights Summers
Alamo Heights humidity is real. Older systems struggle with long run times, and when they short-cycle, they never pull enough moisture out of the air. A properly sized heat pump runs longer at lower output, which strips more humidity. That’s why we often recommend two-stage or variable-speed equipment for older Alamo Heights homes. It costs more within the $3,500 – $7,500 range, but the comfort difference is dramatic.
Ductless Mini Split Installation in Alamo Heights
Ductless mini split installation in Alamo Heights solves problems central air can’t, especially in historic homes where running new ductwork would mean tearing into plaster and original millwork. A mini split pairs a small outdoor condenser with wall-mounted indoor units, each with its own thermostat. No ducts. No crawlspace surgery. Alamo Heights homeowners choose this route for additions, converted garages, sunrooms, or specific rooms that never cool evenly. Expect to pay $3,500 – $7,500 for a typical Alamo Heights installation, depending on the number of zones.
Zoned Comfort for Uneven Floor Plans
Older Alamo Heights homes rarely cool evenly. The living room freezes while the back bedrooms bake. Mini splits fix that at the source because each indoor unit controls its own zone. You set the bedroom to 72 and the living room to 75, independently. For homes with original single-pane windows or rooms that face west with no shade, a ductless system is often the only way to make every room comfortable without replacing every window in the house.
When Ductwork Is the Problem, Not the AC
If your Alamo Heights home has original ducts that leak 20 – 30% of conditioned air into the crawlspace, adding a bigger central unit won’t help; it’ll just blow more money out the same holes. In cases like that, we’ll quote a ductless option honestly. Sometimes the better fix is sealing existing ducts with Aeroseal. Sometimes it’s a mini split in the trouble room. We’ll show you the numbers and let you decide. That’s the whole point of a written price before work starts.

AfterCommon AC Installation Problems We See in Alamo Heights Homes
- Undersized original ductwork causing high static pressure. Many Alamo Heights homes still have sheet-metal ducts sized for gravity furnaces from the 1930s and 40s. When a modern high-efficiency system pushes air through them, the blower works against resistance it wasn’t designed for, shortening its life and leaving far rooms hot.
- Outdated 100-amp electrical panels that can’t support a heat pump. Homes in the older sections of Alamo Heights often still run on 100-amp service. A new high-efficiency heat pump with electric backup heat can trip that panel. We’ll flag it before installation, not after you’ve lost power on a 105-degree day.
- Pier-and-beam foundations allowing duct runs to sag and separate. Crawlspaces in Alamo Heights aren’t kind to ductwork. Poor support causes joints to pull apart, leaking a quarter or more of your conditioned air into the dirt below the house. That’s money you’re paying every month for air that never reaches a bedroom.
- Window units patched into exterior walls creating uneven cooling. We regularly open walls in older Alamo Heights homes to find window AC units that were framed in decades ago. They cool one room and nothing else, and they usually leak air around the framing. Replacing them with a properly sized central system or a ductless mini split changes the entire feel of the house.

FAQs About AC Installation in Alamo Heights
You won’t know without measuring it, and that’s exactly what a Manual J load calculation and a static pressure test do. In older Alamo Heights homes with original gravity furnace ducts, the answer is usually no, not without sealing or modification. We check before we quote equipment, so you don’t buy a 3-ton system that needs 1,200 CFM when your ducts can only move 900 CFM. Call (903) 623-6784 and we’ll test it.
Often yes, and we encourage it in historic Alamo Heights homes where original floor grilles are part of the character. What matters is the duct run underneath, not the grille itself. If the duct is undersized, we can sometimes upsize the trunk line while retaining the original grille covers. It’s a detail we handle carefully on older homes. Call us for a site visit and we’ll walk you through what’s possible.
Yes. We see this constantly in older Alamo Heights homes where window units were framed in as a quick fix decades ago. The fix usually involves removing the unit, repairing the wall, and either extending central ductwork to that room or installing a ductless mini split. We’ll quote both options with real numbers before you choose. Call (903) 623-6784 to schedule a look.
Maybe, but not always. A high-efficiency heat pump with electric backup heat can draw more than a 100-amp panel safely delivers, especially in a house that also runs an electric oven, dryer, and water heater. We’ll do a load calculation on your panel. If a subpanel upgrade is needed, that goes into the written quote upfront, not as a surprise later. Call us and we’ll check your panel before you spend a dime on equipment.
The fix usually starts with ductwork, not a new AC. In older Alamo Heights homes, sagging or separated duct runs in the crawlspace leak conditioned air before it ever reaches the far rooms. Sealing those ducts, or adding a zoning system, or installing a ductless mini split in the problem bedroom, are all options we quote with written prices. The wrong fix is buying a bigger unit and hoping. We’ll show you the actual numbers. Call (903) 623-6784 for a free estimate.
