C&A Air Conditioning & Heating: Experienced HVAC Repair Serving Houston, TX 77083

Common signs include your outdoor unit humming but not starting, random system shut-offs, or a hard start where the unit strains to turn on. Houston's intense, prolonged heat causes capacitors—which help start the motors—to overwork and fail faster. We can test and replace a failing capacitor quickly to prevent a complete AC breakdown during our hottest days.

Signs include uneven cooling between rooms, excessive dust, higher-than-normal energy bills, and your system running constantly. Leaky ducts force your HVAC unit to work much harder to maintain temperature, wasting cooled air into attics or crawl spaces. Our technicians perform duct testing and sealing to improve efficiency, balance your home's temperature, and reduce your monthly cooling costs.

Our thorough maintenance includes inspecting and cleaning key components, checking electrical connections, testing capacitors for early signs of wear, examining ductwork for leaks or restrictions, and ensuring optimal refrigerant levels. This proactive service helps catch small issues before they lead to costly repairs, extends your system's lifespan, and keeps it running efficiently through Houston's demanding seasons.
