Why Meadowsweet Heating & Air Is San Antonio’s Preferred AC Installation Company
San Antonio homeowners call us because the crew shows up in uniform, puts down drop cloths before the first tool comes off the truck, and writes the price down before any work begins. That’s the Cedarwell Care Promise, and it’s been the standard since 2004. Luis Serrano leads our team with a simple rule: leave the house cleaner than we found it, and explain the price in plain English before the first screw turns.
Our AC Installation team works across the full San Antonio metro, from Converse to Helotes. A live person answers the phone 24 hours a day, including nights and weekends, so when a system fails during a July heat wave you won’t sit through a voicemail queue. We serve nine equipment brands, stock common parts locally, and back every job with the 365-Day Done Right Promise. If it’s not done right, we make it right. No runarounds, no fine print.
Heat Pump Installation in San Antonio
Heat pump installation in San Antonio has shifted from a niche choice to a mainstream one since Winter Storm Uri brought the city to near 8°F in February 2021. A properly sized heat pump handles both the 100°F-plus cooling season and the sharp blue-norther cold snaps San Antonio gets every few winters. Most heat pump installs in San Antonio fall within the same $3,500-$7,500 range as a standard AC, with the added benefit of efficient heating in shoulder months when the furnace would otherwise cycle on.
For homes on San Antonio’s northwest side, where the Balcones Escarpment keeps Helotes and Leon Springs 4-6°F cooler than the South Side, a heat pump’s defrost and cold-weather performance matters more. We account for that in the load calculation. Every heat pump install includes drain-line flushing, refrigerant charge verification, and a written report of what was installed and why.
Dual-fuel and freeze-protection options
Many San Antonio homeowners who lived through Uri want a hybrid setup: a heat pump for mild weather plus a gas furnace for the coldest nights. We install dual-fuel systems with a control board that switches automatically at the balance point we calculate for your specific house. Freeze-protection add-ons, like insulated refrigerant lines and secondary drain pan heaters, are worth discussing if your condenser sits on a north-facing wall.
Load calculation before any equipment order
We don’t order a heat pump until we’ve run a room-by-room Manual J. A Helotes two-story and a Lackland ranch need different tonnage, even if both are 2,400 square feet. The calculation also tells us whether your ductwork can handle the airflow a heat pump needs in heating mode, which is a common overlooked failure point.
Ductless Mini Split Installation in San Antonio
Ductless mini split installation in San Antonio solves the problem that a lot of older tract homes share: the central system can’t keep specific rooms comfortable, and running new ductwork through unconditioned attics that hit 150-160°F in summer is expensive and inefficient. A mini split puts a small indoor unit on the wall of the problem room, with a dedicated outdoor condenser, so you get zone control without tearing open drywall.
We install ductless mini splits in San Antonio garages, sunrooms, enclosed patios, and upstairs bedrooms that never hold setpoint. Cost depends on the number of indoor heads and the condenser capacity, but a single-zone mini split install typically starts around $3,500 and a multi-zone system can reach the $7,500 range depending on the layout. Every quote is written, itemized, and explained before we start.
Two-zone solutions for upstairs bedrooms
When a two-story Alamo Ranch or Stone Oak home has one builder-grade system for the whole house, the upstairs bedrooms typically run 6-8°F warmer than the downstairs in July. Rather than replacing the central unit with a bigger condenser, which often makes static pressure worse, we’ll install a ductless mini split for the upstairs zone. The result is real temperature control where you sleep, not more airflow where you don’t need it.
Garage and workshop comfort
San Antonio garages bake in the summer, especially south-facing ones. A ductless mini split keeps a garage workshop or gym under 80°F without extending the main system. These installs are typically single-zone and straightforward, with a line set run through an exterior wall and a drain routed to the outside with proper mineral-deposit protection.
Trusted Brands We Service in San Antonio
We install and service Goodman, Rheem, York, and Daikin equipment, along with five other major brands, so you’re not locked into one manufacturer’s ecosystem. For San Antonio specifically, we keep common replacement parts for these brands in local stock, which means a capacitor or blower motor swap doesn’t wait on a Dallas warehouse. That local parts access matters in August when a system is down and the heat index is 110. Whether you want a budget-conscious Goodman install or a premium Daikin heat pump, the sizing and the installation quality are the same standard.
Common AC Installation Problems We See in San Antonio Homes
- Builder-grade sizing by square footage, not load calculation. In Stone Oak and Alamo Ranch two-story tract homes, the original system was often sized by the builder’s rule of thumb, so the upstairs never holds setpoint by the first July. We fix this with a proper Manual J and a two-zone split or ductless addition, not a bigger condenser.
- Undersized returns and high static pressure. Many San Antonio homes, especially 1990s-era construction, have return air openings too small for the system’s airflow requirements. The evaporator coil starves, the system ices in the attic, and homeowners get told the brand is bad when the ductwork was never right.
- Builder-registered warranties that never transferred. In new-construction neighborhoods, the builder often registers the AC warranty under their own company name. When the first capacitor fails in year three, the homeowner discovers the parts warranty was never actually transferred. We check this on every install and register the new equipment under the homeowner’s name on the spot.
- Condensate drain lines clogged with mineral scale. San Antonio’s water, drawn from the limestone Edwards Aquifer, is among the hardest in Texas. Drain lines scale up with mineral deposits far faster than in Houston or Dallas, which is why we flush the drain line on every install and recommend quarterly pan treatments.

FAQs About AC Installation in San Antonio
Because your builder almost certainly sized the original system by square footage instead of running a room-by-room Manual J load calculation. The second floor of a two-story tract home gets direct attic heat, longer duct runs, and more window surface than a single-story, but the builder installed one system sized for the whole house. The fix is usually a proper two-zone split or a ductless mini split for the upstairs, not a bigger condenser. Call (747) 966-3037 and we’ll run the calculation your builder skipped.
Usually not, and in many San Antonio new builds the builder registered the equipment warranty under their own company name, so the parts coverage was never actually transferred to you. We check the registration status on every install and register the new equipment under the homeowner’s name, on the spot, before the crew leaves.
Yes, and it’s the fastest-growing install category we see in San Antonio since Uri. A heat pump cools just as well as a standard AC in the summer and heats efficiently during the mild shoulder months, with most units now performing well into the 20s Fahrenheit. For the extreme cold snaps, a dual-fuel system with a gas furnace backup is worth considering. We’ll explain the cost difference in writing before you commit.
A complete AC installation in San Antonio runs $3,500 to $7,500 depending on home size, zoning needs, equipment efficiency, and whether ductwork requires modification. Every quote is written, itemized, and fixed before work begins. Call (747) 966-3037 for a free estimate, and we’ll measure the house properly before giving you a number.
Because San Antonio’s water, pulled from the limestone Edwards Aquifer, is among the hardest in Texas. Mineral deposits scale up condensate drain lines far faster than in Houston or Dallas, which means a clogged drain and a pan overflow in a hot attic can happen within two summers. We flush the drain line on every install and show you how to check the clear trap.
If you’re ready to replace a builder-grade system, add a heat pump, or fix an upstairs that never cools, call (747) 966-3037 today. A live person answers, 24 hours a day. We’ll schedule a time, measure your home, and give you a written price before any work starts.
