Is a Ductless System Right for My Home?

A ductless system is a strong fit for homes without ductwork, rooms that stay hotter than the rest of the house, and spaces like additions, sunrooms, converted garages, and garage apartments. Each indoor unit has its own controls, so you can cool the rooms you use without running a whole-house system. Your service professional reviews layout, insulation, and electrical access during the estimate to confirm the fit

How Much Does Ductless AC Installation Cost?

Ductless AC installation cost depends on the number of indoor units, equipment size and efficiency, line set length, and electrical work required, so Aire Serv of Alamo Heights prices each project by the job after seeing the space. A projected phone estimate can help you plan, and system replacements include a free in-home estimate. Financing is available, and warranty packages can be added for extra coverage.

How Long Does Mini-Split Installation Take?

Many single-zone mini-split installations are finished in one day, while multi-zone systems and projects that need new electrical circuits or long line set runs can take longer. The schedule depends on how many indoor units are going in, wall construction, and where the condenser will be placed. Your technician walks you through the expected timeline before any work begins.

What Size Mini-Split Do I Need?

Mini-split size is determined by a load calculation that measures how much heat each room gains, based on square footage, insulation, ceiling height, windows, and sun exposure. An undersized unit runs nonstop without reaching your set temperature, while an oversized unit short-cycles and removes less humidity. Correct sizing supports steady comfort and efficient operation through a long Texas cooling season.

What Warranty Comes With a New Ductless System?

New ductless equipment typically includes a manufacturer warranty on parts, and Aire Serv of Alamo Heights offers warranty packages for additional coverage. Installation work is backed by the Neighborly Done Right Promise®, so if a problem traces back to our work, we fix it at no charge. Your service professional explains the coverage for your specific equipment before you approve the project.

When Should I Replace My Mini-Split?

Replacing a mini-split usually makes sense when the system is 15 years or older, needs frequent repairs, leaks refrigerant, or no longer keeps rooms comfortable on the hottest afternoons. Climbing energy bills also point to declining efficiency. A technician can compare repair and replacement pricing, and if you move forward with a new system, the diagnostic fee for your old unit is waived.

Why Alamo Heights Homeowners Choose Us for Ductless Installs

In-home evaluations, fixed project pricing, and coverage options that extend past install day.

Every ductless replacement starts with a free in-home estimate. Your Aire Serv of Alamo Heights service professional evaluates how much heat each room gains through windows, walls, and the roof, then recommends indoor units sized for that load. We can give a projected estimate by phone to help you plan, but we prefer to see the space, because line set routes, wall construction, and electrical capacity all affect the final price. The quote covers the full job, not an hourly rate, so your Alamo Heights project costs what you approved.
Installation and estimate appointments run from 8 a.m. to 7 p.m., with Saturday availability at an additional charge. Same-day visits are available when a technician is open, and calls are answered 24/7. If you called because an existing mini-split failed, the diagnostic fee is waived when you move forward with a new installation through our Free Second Opinion offer. Many single-zone installs are completed in one day, and your technician explains the timeline for larger multi-zone projects before work begins.
New ductless equipment typically carries a manufacturer warranty on its parts, and Aire Serv of Alamo Heights offers warranty packages for added protection. If an issue traces back to our installation, we correct it at no charge under the Neighborly Done Right Promise®. Financing is available to spread the cost of a new system into payments. We are fully insured, and seniors, military, first responders, and teachers receive 10% off service, applied when it is the best available offer.

Our Ductless AC Installation Process

A ductless installation begins with a load calculation for each room, factoring in square footage, insulation, ceiling height, window area, and afternoon sun exposure that is intense during an Alamo Heights summer. Your service professional uses those results to select single-zone or multi-zone equipment and to plan where each indoor unit and the outdoor condenser will sit. On installation day, the technician protects floors and furnishings, mounts the indoor units, and drills a small exterior wall opening for the refrigerant line set, drain line, and control wiring. The condenser is set on a level pad or wall bracket with clearance for airflow. After connecting the lines, the technician pulls a vacuum to remove moisture, pressure-tests for leaks, and verifies the refrigerant charge. Each zone is then tested for correct airflow and temperature. For replacements, old equipment is removed and disposed of properly.
