ARC Air Conditioning and Heating - Round Rock's Emergency HVAC Services

Common signs include reduced cooling, longer run times, ice on the evaporator coil, and higher energy bills. For Round Rock homeowners, we start with a precise electronic leak detection to find even the smallest leaks. Our repair process involves sealing the leak, performing a vacuum test to ensure the system is sealed, and then recharging it with the exact manufacturer-specified refrigerant amount to restore optimal efficiency and cooling capacity.

Short cycling is often caused by an oversized unit, a dirty air filter, low refrigerant, or a faulty thermostat. Given our local climate, it puts extra strain on the compressor. We perform a comprehensive diagnosis to pinpoint the exact cause—checking charge levels, airflow, electrical components, and thermostat calibration. Fixing this not only restores comfort but prevents premature system failure and lowers your monthly cooling costs.

Our local weather demands a lot from HVAC systems. Regular maintenance is crucial to prevent common issues like refrigerant leaks and short cycling before they start. Our tune-up includes cleaning coils, checking refrigerant levels, calibrating thermostats, and inspecting electrical connections. This proactive care improves efficiency, extends your system's lifespan, and helps avoid costly emergency repairs during our hottest summers and occasional cold snaps.
