A new central air system in Kirby typically runs $3,500 to $7,500 depending on the size of your home, the condition of your ductwork, and whether your electrical panel needs an upgrade. We schedule most Kirby installations within a week, and you’ll get a written price before any work starts. If your existing AC wheezes through another triple-digit afternoon and you’re done crossing your fingers, call Halden Heating and Air San Antonio at (903) 623-6784 for a free estimate. We answer live, around the clock, and we know Kirby’s older homes well enough to tell you the truth before you spend a dollar.
Why Halden Heating and Air San Antonio Is Kirby’s Preferred AC Installation Company
Kirby homeowners tend to be wary of HVAC companies that show up late, push a fast replacement, and hand over a surprise invoice. That’s exactly the pattern Halden Heating and Air was built to break. Founded in 2004 and operating under the Relay Home Co. network, we run on a simple standard: a written price before any tool comes off the truck, a live arrival time you can track to your door, and a 365-Day Done Right Promise on every completed job.
We’ve worked on enough Kirby streets, from the neighborhoods off Binz-Engleman Road to the houses tucked behind Kirby Middle School, to know that most of these homes were built between the 1950s and 1970s. That means slab foundations, original duct trunks, and electrical panels that weren’t designed for a modern high-efficiency system. Andre Fuller, who leads our team, insists on a full assessment before recommending anything. The Relay Visibility Guarantee backs every install: if it’s not done right, we make it right. No fine print gymnastics.
Every technician who comes to Kirby is background-checked and uniformed. You’ll see a live arrival time on your phone, not a four-hour window. And if a repair fails inside the guarantee window, we return free. That’s not a courtesy. It’s how we run.

Ductless Mini Split Installation in Kirby
Ductless Mini Split Installation in Kirby is the cleanest fix for a home where the original ductwork is too leaky, too small, or practically nonexistent in a room addition. Older Kirby houses often have no attic access or have been expanded over the years with add-on rooms that the original duct system never reached. A mini split puts a small indoor air handler directly on the wall and connects it to an outdoor condenser through a three-inch opening, so you can cool a hot back bedroom without tearing into ceilings or replacing a whole trunk line.
When a Kirby Homeowner Should Choose Ductless
If your back bedrooms run eight to ten degrees warmer than the thermostat in the hallway, a ductless mini split for those rooms usually beats a full duct replacement on cost and disruption. It’s also the practical choice for a converted garage, a sunroom, or a mother-in-law suite on a slab.
Mini Split Pricing in Kirby
A ductless mini split installation in Kirby runs $3,500 to $7,500 depending on how many indoor heads you need and whether your panel has spare capacity. We give you a written fixed price before ordering equipment, and our crews handle the electrical, the refrigerant charging, and the condensate line routing.
AC Replacement in Kirby
AC Replacement in Kirby is less about swapping a box and more about matching a new system to a house built when Richard Nixon was in office. If your condenser died and a sales rep tells you a like-for-like swap will fix everything, walk away. In an older Kirby home, the outdoor unit is only half the story. The evaporator coil, the blower motor, the duct sizing, and the electrical feed all have to agree, or your new system will underperform the same rooms the old one did.
Matching the Condenser to the Coil
Original 1970s homes often get a new outdoor condenser paired with a 20-year-old evaporator coil. That mismatch kills efficiency and shortens compressor life. We replace coils and condensers as a matched set, and we check static pressure before we install.
What Kirby Replacement Costs
A full AC replacement in Kirby falls in that $3,500 to $7,500 range. The variables are your square footage, whether you need duct sealing or electrical work, and how much duct correction the house demands. You’ll see every line item in writing before we start.
Trusted Brands We Service in Kirby
Our Kirby customers most often ask about Rheem, York, and Daikin, and we service and install all three along with other major equipment lines. We keep common parts stocked locally so a failed capacitor or contactor doesn’t leave your family sweating through a weekend waiting on a warehouse shipment. Whether you’re replacing a 1972 Rheem electric furnace with a modern heat pump or putting a new Daikin condenser on a slab home off Loop 410, our technicians are factory-trained to install and service these systems correctly. We won’t push a brand you don’t need. We’ll recommend the equipment your house can actually support.
Common AC Installation Problems We See in Kirby Homes
- Same-tonnage swaps on undersized ducts. The old 2.5-ton condenser gets replaced with another 2.5-ton unit, but the original duct trunk can’t move enough air. The new blower fights against high static pressure, overheats, and dies prematurely. We measure duct capacity before quoting.
- No load calculation on a slab home. A 1960s house with single-pane windows and no wall insulation gets an oversized unit because someone guessed. The system short-cycles, leaving cold but clammy air and high electric bills. Manual J load calculations prevent this.
- Ignoring the electrical panel. Older Kirby homes often have 100-amp panels that were never meant to carry a modern heat pump or high-efficiency condenser. If we install without checking, the breaker trips during peak heat. We inspect panel capacity on every bid.
- Mismatched coils and condensers. New outdoor unit, old indoor coil. Efficiency ratings collapse, and the compressor works harder than it should. In a humid Kirby summer, that means poor dehumidification and shorter system life. We only install matched systems.

FAQs About AC Installation in Kirby
Because the ductwork was sized for a heating-only furnace, not a cooling system. Kirby’s 1950s – 1970s slab homes often have long, narrow duct runs with undersized branch lines to the back rooms. When you put a new condenser on that same duct system, the back bedroom still starves for airflow. The fix is usually duct sealing, adding a return, or installing a ductless mini split for that room. Call (903) 623-6784 and we’ll measure your static pressure to find the bottleneck.
Sometimes, yes, if the furnace blower can move enough air and the cabinet can accept a proper cooling coil. But many original Kirby electric furnaces have blowers sized for heat only. Adding a condenser without checking airspeed leads to frozen coils in summer and a dead blower within two seasons. We’ll inspect the furnace before quoting anything.
You’ll need a load check on your panel. Older Kirby homes frequently have 100-amp service, and a modern heat pump with auxiliary heat strips can pull more than that panel was designed to deliver. Some installations work fine with a dedicated double-pole breaker. Others need a panel upgrade or a sub-feed. We include this check on every installation bid, and you’ll see the answer in writing before you decide.
Skipping the static pressure measurement and matching tonnage to the old unit instead of the actual duct capacity. We pulled a 1972 Rheem electric furnace out of a Kirby home on Elm Street and found the original duct trunk had just 0.3 inches of static pressure headroom. Installing a 3-ton system with a new coil and resealed supply plenum dropped the upstairs bedroom from 82°F to 74°F on a 99°F day without changing the condenser size at all. Same tonnage, different ductwork. That’s the difference a proper assessment makes.
Yes, often the best choice. Many Kirby homes with flat or low-slope roofs have little or no attic to run new ducts, and the original duct runs are already undersized. A ductless mini split avoids the duct problem entirely. It costs $3,500 to $7,500 for a typical installation, and it lets you cool hot rooms independently without tearing up walls. We’ll tell you if a mini split makes more sense than a full replacement.
