HVAC Company in Katy, TX
Meadowsweet Heating & Air is the HVAC company Katy families call when a system fails during a 105°F afternoon or starts making a sound it has never made before. Our work across Katy focuses on large two-story homes in master-planned communities, where attic temperatures routinely reach 140°F and builder-grade equipment from the 1990s and 2000s is now hitting the end of its life all at once. We service equipment from nine major brands, give a written price before work begins, and back every job with our 365-Day Done Right Promise. If your AC or furnace needs attention in Katy, call (747) 966-3037 and a live person answers, any hour, any day.
Why Katy Homes Are Different
Katy’s housing stock creates a set of HVAC conditions you will not find in most Houston suburbs. The master-planned communities that define the area – Cinco Ranch, Grand Lakes, Seven Meadows, and others – were built in a concentrated window, largely between 1993 and 2012, and the original equipment was spec’d to minimum efficiency standards. Those systems are now 13 to 30 years old. In a majority of Katy’s two-story brick-veneer homes, the air handler sits in an unconditioned attic, and the ductwork runs through the same superheated space. On a July afternoon, that attic can reach 140 to 150°F, which means the system works harder than the outdoor temperature alone would suggest.
We also see a second, quieter problem more often in Katy than almost anywhere else we work: flex-duct connections at the plenum and at register boots have separated or collapsed from years of thermal cycling. When a homeowner in Cinco Ranch says the upstairs bedrooms never cool down no matter what the thermostat is set to, the answer is usually not the unit itself. It is conditioned air leaking into the attic, sometimes 25 to 35 percent of the total. That is a fixable problem, but it takes a technician who knows to look for it before recommending anything else. Katy’s humidity compounds everything. The flat Katy Prairie traps Gulf moisture against the western edge of the metro, and compressors run nine or more months per year. An oversized single-stage system short-cycles, never fully dehumidifies, and leaves the house feeling clammy even at 74°F.
Our Main Katy Services
Most calls we take in Katy fall into one of three categories, and each has its own dedicated page with local pricing, specific repair details, and what to expect on the day we arrive.
AC Repair in Katy
When an air conditioner fails in Katy between June and September, the indoor temperature climbs fast, and the indoor humidity climbs faster. AC Repair in Katy means diagnosing everything from a failed capacitor to a refrigerant leak to a dead compressor, but it also means checking the attic side of the system, because in Katy’s 140°F attics, the ductwork is often the real culprit behind uneven cooling. We carry parts for most major brands on the truck and give you a written price before any repair begins, so you decide with clear numbers in front of you, not a guess after the work is done.

Furnace Repair in Katy
Katy’s furnaces get less annual use than the AC, but when a cold front sweeps across the Katy Prairie in January, a failed furnace moves from inconvenience to urgent quickly. Furnace Repair in Katy covers gas furnaces in two-story homes where long duct runs and two zones mean the upstairs and downstairs rarely behave the same. Our technicians check the heat exchanger, the inducer motor, the flame sensor, and the safety switches – and they will tell you plainly if a part is still serviceable or if replacement is the honest recommendation. Like every Meadowsweet visit, the repair price is written down before tools come out.

AC Installation in Katy
Katy is in the middle of a replacement wave that no neighboring suburb faces at this scale. Tens of thousands of 13 to 14 SEER single-stage systems installed in the 1990s and 2000s are reaching end-of-life in the same concentrated ZIP codes, often within a few years of each other. AC Installation in Katy starts with a load calculation and a close look at your existing ductwork, because in a Katy attic, the wrong size new unit will never dehumidify properly. You get a fixed written price, a set install date, and our crew leaves your floors covered and your home as clean as they found it. For installs, we also make sure rebate and financing paperwork is handled before any equipment is ordered.

Katy prices trend toward the upper end of repair ranges when the diagnosis requires an extended attic inspection in 140°F conditions, which is common in the two-story master-planned homes we serve. Before any work begins, you receive a written price in dollars – not an estimate spoken over a phone, not a range to be revised. That price does not change unless you approve additional work first.

- Marcus Pell"Comfortable in every room now, and not a trace that a crew had been here. Booties, drop cloths, the works. They even wiped down the thermostat they'd handled. Really considerate."
