Need cooling for a garage, addition, or room that's always too hot? Mini-splits deliver powerful, efficient zone cooling without ductwork — and we install them in a single day.
Get a Free EstimateDuctless mini-split systems have become one of the fastest-growing HVAC solutions in the Katy area, and for good reason. They solve problems that traditional central AC systems can't — cooling spaces without ductwork, adding independent temperature control to specific rooms, and providing ultra-efficient heating and cooling to targeted areas of your home.
Converted Garages and Workshops: Katy homeowners are increasingly converting attached garages into home gyms, workshops, or living spaces. These rooms don't have ductwork, and extending your central system is expensive and often impractical. A single mini-split unit can cool a 2-car garage space effectively, even in peak Katy summer heat.
Bonus Rooms Above Garages: These are the hottest rooms in any Katy home. The garage below acts as a heat collector, and the roof above radiates heat down. Central AC struggles to reach these spaces through long duct runs. A dedicated mini-split keeps bonus rooms 10-15°F cooler than relying on the central system alone.
Home Additions and Sunrooms: When you add a room to your Katy home, connecting it to the existing ductwork is often the most expensive part of the project. A mini-split eliminates that cost entirely while providing better temperature control than a duct extension would.
Home Offices: With more Katy residents working from home, keeping one room comfortable during work hours without cooling the entire house makes financial sense. A mini-split in a home office can save $50-80/month in electricity compared to running the central system all day for one room.
Older Katy Homes Without Ductwork: Some older homes in the Katy area, particularly in historic downtown Katy, were built before central air was standard. Adding ductwork is invasive and expensive. Multi-zone mini-splits can cool an entire home — 2, 3, or 4 rooms — from a single outdoor unit without any ductwork.
A mini-split system has two main components: a compact outdoor compressor/condenser unit and one or more indoor air-handling units. The two are connected by a small refrigerant line that requires only a 3-inch hole through the wall — no ductwork, no major construction.
Single-zone systems have one outdoor unit and one indoor unit, perfect for cooling a single room like a garage or addition. Multi-zone systems connect one outdoor unit to 2-5 indoor units, each with independent temperature control. You can set the bedroom to 68°F for sleeping while keeping the living room at 74°F — something central AC can't do.
Modern mini-splits use inverter compressor technology, which means they don't just cycle on and off like traditional AC. Instead, they continuously adjust output to match the cooling demand. This makes them exceptionally efficient — top models achieve SEER2 ratings above 20, compared to 15-18 for most central systems.
Most single-zone mini-split installations are completed in 4-6 hours — start to finish in one day. Here's the process:
Multi-zone installations take 1-2 days depending on the number of indoor units and routing complexity.
A single-zone system typically costs $2,500-$4,500 installed. Multi-zone systems (2-4 rooms) range from $5,000-$12,000 depending on capacity and number of zones. We provide free estimates with exact pricing for your setup.
Yes. Modern mini-splits use inverter technology that adjusts output continuously. Top models achieve 20+ SEER2 ratings, making them among the most efficient cooling systems available. They handle Katy's 100°F+ summers effectively.
