US Thermodynamics - San Marcos's Local HVAC Repair

A proper installation is the first defense against energy loss. Our team doesn't just install the unit; we perform a thorough evaluation of your existing ductwork. We identify and seal leaks at connections and in the attic or crawlspace, which are common in older San Marcos homes. This ensures your new, efficient system delivers all its conditioned air directly into your living spaces, maximizing performance and lowering your monthly bills from day one.

Watch for water pooling around your indoor air handler or furnace, musty odors when the AC runs, or the system shutting off unexpectedly. San Marcos' humidity means your AC produces a lot of condensation. Over time, algae and mold can clog the drain line. Our repair service includes safely clearing the blockage, flushing the line, and can install a safety float switch to prevent future water damage—a quick fix that protects your home and system.

Absolutely. It's a critical part of our replacement service. Installing a new, efficient unit on leaky ducts is like putting a new engine in a car with flat tires. We assess your duct system's integrity and seal any leaks we find. This addresses a key local efficiency issue, ensuring you get the full comfort and savings you paid for with your new system. We consider the entire system, not just the equipment, for a complete solution.
