A new air conditioning system in Houston typically costs $3,500 to $7,500 for a complete central system replacement, and most installs take one day once equipment arrives. That price range covers everything from a straightforward 2.5-ton swap in a 1970s ranch to a multi-zone, high-SEER2 system in a newer Memorial or West University custom. We install across Harris County, Fort Bend County, and Montgomery County with scheduling that respects school hours, nap times, and your workday. Call (346) 201-5395 for a written, fixed-price quote before you commit to anything.

Houston’s climate presses an AC system harder than almost any other city in the country. That’s not marketing language, it’s measured reality: the cooling season runs from March through October, nighttime lows in July and August often stay above 80°F, and a running system pulls 60 or more pints of moisture from the air every single day. We design and install equipment for exactly that load. Luis Serrano founded the Houston team on a simple rule: if the system can’t hold humidity under 55% on a 98°F afternoon in Meyerland, it wasn’t installed right. And if it’s not done right, our 365-Day Done Right Promise means we come back and make it right, no phone tag, no fine print.
Why Meadowsweet Heating and Air Houston Is Houston’s Preferred AC Installation Company
We are not the biggest HVAC contractor in Houston, and that’s intentional. We’re built around the Cedarwell Care Promise, which has backed every job since 2004. That promise means three things on every single visit, no exceptions: a written price before any work starts, shoe covers and drop cloths inside your home, and a photo of the clean-up before the crew leaves. Families with kids and pets tell us that last one matters more than any warranty card. Your floors stay clean. Your dog doesn’t eat drywall dust. Your toddler’s play mat doesn’t get a boot print.
Our Houston crews are background-checked and uniformed, and they follow a code we actually train on, not a poster on a wall. The C.A.R.E. values: clean up like it’s their own home, ask before moving anything, respect the family’s time and quiet hours, and explain the price before the work. We know Houston neighborhoods, from the 1960s brick veneer tracts in Sharpstown to the custom two-stories in Bellaire and the sprawling master-planned communities out toward Katy and Sugar Land. Dispatch and scheduling are coordinated from our Houston office, so the crew working on your system drives Houston roads every day, not once a quarter.
Luis Serrano has made one thing clear to every technician who wears a Meadowsweet shirt: we spec for humidity first, square footage second. That’s the difference between an install that cools and an install that works. You can reach a live person at (346) 201-5395 any hour, any day, no voicemail queue.
Styles & brands we work with







Central Air Conditioning Installation in Houston
Central Air Conditioning Installation in Houston is the core of what we do, and it’s where most homes run into real trouble because the equipment selection and duct design have to account for a humid subtropical climate that pushes systems to run continuously for six months straight. A complete replacement, including the outdoor condenser, indoor evaporator coil, refrigerant lines, and a new thermostat, runs $3,500 to $7,500 in Houston. If your home’s ductwork is original to a 1970s or 1980s build, we’ll likely recommend return upsizing as part of the job, which falls within the same $3,500 to $7,500 line-item range for duct modification during install.
Two-Stage and Variable-Speed Systems for Houston’s Humidity
Single-stage equipment, the cheapest thing on any quote, satisfies a thermostat fast but it can’t run long enough to pull the 60-plus pints of daily moisture out of Houston air. That’s why families in River Oaks and Memorial feel clammy even when the thermostat says 72. A two-stage or variable-speed system, running on a low stage for hours, pulls humidity constantly. That’s not a luxury feature in Houston; it prevents mold around supply registers in closets and that damp smell in upstairs bedrooms.
Manual J Load Calculations Before Any Equipment Is Ordered
We run a Manual J load calculation on every install. Not a rule-of-thumb square footage chart, but a room-by-room calculation using your actual window orientation, insulation, ceiling height, and duct layout. Houston’s unzoned sprawl means we routinely find same-size lots with wildly different AC needs: a 1970s Sharpstown ranch with original 14-inch returns two streets over from a 4,000-sq-ft Memorial custom where the builder undersized the duct branch for the primary suite. Both homes are 2,400 square feet. They need very different systems. The Manual J tells us which one you need.
Furnace Installation in Houston
Furnace Installation in Houston often happens as part of a full system replacement, since the indoor furnace cabinet houses the evaporator coil for the air conditioner. A standalone furnace install, or one paired with a new AC during the same job, runs $3,500 to $7,500 in Houston. Most Houston homes have attic-mounted horizontal furnaces, which means the equipment sits in a space that regularly hits 140°F from May through September, and all the supply and return ductwork runs through that same unconditioned attic. Getting the furnace right is less about heating (though January nights do dip) and more about making sure airflow through the coil is correct for the cooling load.
Gas Furnace and Heat Pump Options for Houston Winters
Houston winters are short but real. A furnace installation here usually means a gas furnace paired with an air conditioner, though more homeowners in the Energy Corridor and Sugar Land are asking about heat pump systems as gas rates shift. We’ll show you the numbers for both. The installed price lands in the same $3,500 to $7,500 range, and we’ll explain the trade-offs without steering you toward the higher-commission option. Our technicians are not paid on what they sell.

Attic Installations That Don’t Sweat and Sag
If we’re replacing the furnace or air handler in a Houston attic, we’re also looking hard at the ductwork. Original flex duct from the 1970s through 2000s often has R-4.2 insulation that’s degraded to nothing, with sagging runs that pull humid attic air into the supply plenum. Replacing that duct, or at minimum sealing and re-insulating it, is part of what makes a new system actually feel new. We’ll show you photos of what we found before we touch anything, and a written quote for the fix.
Trusted Brands We Service in Houston
We service and install Carrier, Trane, Lennox, and Goodman equipment, and our Houston shop stocks common parts for all four lines so we’re not waiting on a distributor in another city when your install hits a snag. That matters in August. We’re qualified on nine major brands in total, including Rheem, York, Daikin, Bryant, and American Standard, which means we can support the system you already have while giving you honest guidance on replacement options. No brand steering. No “we only work on X” limitations. We pair the right equipment with the right duct design, or the new system won’t deliver what its specs promise, regardless of whose logo is on the cabinet.

AfterCommon AC Installation Problems We See in Houston Homes
- Undersized return ducts on 1960s – 80s tract homes. Homeowners in Sharpstown, Meyerland, and the East End often have a single 14-inch return serving an entire floor. When we replace the condensing unit with a higher-tonnage system without addressing that return, the evaporator coil freezes on the first 95°F day. Our installs include static pressure measurement before we finalize the design.
- New condensers bolted to dead ductwork. A 145°F attic destroys flex duct insulation. We regularly remove original R-4.2 duct that has collapsed to 40% of its original diameter, killing airflow and pulling hot, humid attic air into the supply. A new high-SEER2 system on that duct runs like a 13 SEER system, and the bedroom at the end of the run never cools.
- Multi-zone panels set to factory default. High-end customs with zoning panels often freeze upstairs and barely run downstairs because the installer left blower speeds and bypass dampers at default settings without doing a static pressure test. We balance zones with actual readings, not assumptions.
- Oversized equipment that short-cycles humidity. A 3-ton system on a home that only needs 2 tons satisfies the thermostat in 10 minutes. That’s not enough runtime to pull Houston’s 60-plus pints of daily moisture. The air feels cold but clammy, and mold starts around supply registers in River Oaks closets. We size for load, not for square footage.
Pricing for AC Installation in Houston, TX

FAQs About AC Installation in Houston
A frozen coil almost always means airflow starvation, and in Houston it usually traces to an undersized return duct or collapsed flex in a 140°F attic. A new installation fixes it permanently if and only if we address the ductwork, not just swap the condenser. That’s why every Meadowsweet install includes a static pressure reading before and after. If your current system freezes, call (346) 201-5395 and we’ll diagnose the true cause before quoting anything.
Probably not. Many 1970s brick-veneer Sharpstown homes need 3 to 4 tons when you account for actual insulation, window orientation, and duct layout, not the 5 tons a rule-of-thumb chart spits out. An oversized system short-cycles, leaves humidity high, and costs more up front for no benefit. We run a Manual J load calculation so the number on the quote is based on your house, not a guess. Free estimates at (346) 201-5395.
SEER2 is the 2023 revision of the SEER efficiency test, using more realistic external static pressure readings that better reflect actual installed ductwork. In Houston, where systems run for eight months straight, the difference between a 14 SEER2 and a 17 SEER2 unit adds up in real dollars on your bill every month. We’ll show you the projected operating cost difference in writing so you can decide whether the higher-efficiency unit makes financial sense for your home.
Yes. That is exactly what a properly designed two-zone (or three-zone) system does, with dampers and separate thermostats for each floor. But the zoning only works if we also fix the duct restrictions that cause the imbalance, which in most Houston two-stories means upsizing the return and rebalancing branch runs. Last June we replaced a frozen 2004 Goodman in Meyerland with a two-stage Carrier 17 SEER2 unit, upsized the return from 14 to 20 inches, replaced collapsed flex with R-8, and balanced static pressure from 0.98 to 0.48 inches. The homeowner’s humidity stayed under 55% for the first time in years.
Because the equipment is oversized, the fan is set to auto, or the ductwork is pulling humid attic air into the supply, or all three. A high-SEER2 unit on a short cycle never runs long enough to pull moisture, and a fan set to auto shuts off exactly when the coil is still dripping wet, sending that moisture right back into the house. We set fan speeds, verify airflow, and test static pressure so the system removes the 60-plus pints of daily moisture Houston air forces on it. If you’re in Houston and the house feels clammy with a new AC, call (346) 201-5395.
