What does an AC tune-up include?
Our tune-up covers a full system inspection, cleaning of key components, refrigerant level check, electrical connection review, thermostat calibration, and a performance report. A single tune-up can meaningfully extend your system’s life and reduce energy consumption.
What should I do if my AC stops working at night or on weekends?
Call or text 210-920-1412 — we’re available 24/7 including nights and weekends. Text us your address and a brief description and we’ll coordinate a response as fast as possible.
Can you replace my old AC system and haul away the old one?
Yes. We handle full AC replacement — removal of the old unit, installation of the new system, and proper disposal. Financing is available if you’d like to spread out the cost.
Do you install mini-split systems in San Antonio?
Yes. We install ductless mini-split systems throughout San Antonio — ideal for homes without existing ductwork, garage conversions, room additions, and commercial spaces. All major brands.
How do I know if I need AC repair or a full replacement?
If your system is under 10 years old and the repair cost is less than half the price of a new unit, repair usually makes sense. If the system is 12–15+ years old, running inefficiently, or the repair cost is significant — replacement is often the smarter long-term investment. We give you a straight assessment so you can make the right call.
