Frequently Asked Questions
Everything San Antonio homeowners need to know about ductless mini split systems—from how they work to what they cost.
General Questions
A ductless mini split is a heating and cooling system that delivers conditioned air directly into individual rooms without requiring ductwork. It consists of an outdoor compressor unit connected to one or more indoor air handlers by a small refrigerant line that passes through a three-inch opening in the wall. Each indoor unit controls the temperature in its own zone, giving you precise comfort where you need it most.
Central AC relies on a network of ducts to push air throughout your entire home from a single thermostat. A mini split eliminates the ductwork entirely—each room gets its own air handler and thermostat, so you only condition the spaces you’re actually using. This means no energy lost through leaky ducts, no hot and cold spots, and far more control over individual room temperatures. For San Antonio homes without existing ductwork—older builds, garage conversions, additions—a mini split is often the most practical and cost-effective solution.
Yes. Every mini split system we install is a heat pump, which means it provides both cooling in the summer and heating in the winter using a single outdoor unit. The system reverses the flow of refrigerant to switch between modes. In San Antonio’s climate, a mini split heat pump handles both seasons efficiently without the need for a separate furnace or supplemental heating system.
Installation
A single-zone mini split installation typically takes four to six hours to complete. Multi-zone systems with two to four indoor units usually take a full day. We handle everything in one visit—mounting the indoor and outdoor units, running the refrigerant lines, making electrical connections, and testing the system. We’ll walk you through the controls before we leave so you’re comfortable operating your new system right away.
No—that’s the main advantage. Mini splits need only a small three-inch hole through an exterior wall to connect the indoor unit to the outdoor compressor. There’s no tearing into ceilings or walls to install ducts, no soffits to build, and no crawl space work. This makes mini splits ideal for homes that weren’t built with ductwork, room additions, converted garages, and sunrooms.
The only penetration is the small three-inch hole for the refrigerant line, and we seal it completely with a trim cover when we’re done. The indoor unit mounts flush to the wall on a bracket—no cutting into the wall itself. We protect your floors and furniture during installation and clean up thoroughly before we leave. Most homeowners are surprised at how minimal the footprint is.
Cost & Value
A single-zone mini split system typically ranges from $3,000 to $5,500 installed, depending on the capacity (BTU rating) and the specifics of your space. Multi-zone systems that condition two to four rooms generally range from $6,000 to $14,000. We provide free on-site estimates so we can assess your home and give you an accurate, all-inclusive price—no hidden fees or surprise charges.
Extremely. Modern mini splits achieve SEER2 ratings of 20 or higher, compared to 14–16 for most central AC systems. Because there are no ducts, you eliminate the 25–30% energy loss that’s typical of ducted systems. Zone control means you’re not paying to cool empty rooms. Most San Antonio homeowners see a noticeable reduction in their electric bill—especially during peak summer months when energy costs spike.
Yes. We offer flexible financing options so you can get the comfort you need now and pay over time with manageable monthly payments. During your free estimate, we’ll walk you through the available plans and help you find the option that fits your budget. Qualifying is quick and straightforward.
Service & Maintenance
We recommend a professional maintenance visit once a year—ideally in the spring before San Antonio’s cooling season hits. During a tune-up, we clean the coils, check refrigerant levels, inspect electrical connections, and make sure both the indoor and outdoor units are running at peak efficiency. Between visits, you should clean or replace the filters in your indoor units every four to six weeks. Clean filters keep your air quality high and your system running efficiently.
We install and service Carrier, Hisense, and Daikin ductless systems, which are known for reliability, efficiency, and quiet operation. We also service and repair most major mini split brands, including Mitsubishi, Fujitsu, LG, and Samsung. If you have an existing system that needs repair or maintenance, give us a call—we can help regardless of the brand.
Every installation comes with a manufacturer’s warranty on the equipment—typically 5 to 10 years on parts depending on the model and registration. On top of that, we back our labor with our own workmanship warranty so you’re fully covered. If anything goes wrong with the installation, we’ll come back and make it right at no additional cost. We’ll go over all warranty details during your estimate so there are no surprises.
