A-Z Air Conditioning - Las Vegas's Qualified HVAC Repair

In the dusty Las Vegas climate, we recommend checking your air filter every 30 days and replacing standard 1-inch filters at least every 60-90 days. For homes with pets or allergy sufferers, monthly replacement is often necessary to maintain airflow, prevent strain on your AC unit, and improve indoor air quality.

In Las Vegas, a frozen evaporator coil is often caused by restricted airflow from a dirty filter or low refrigerant levels, both common issues here. Our technicians first safely thaw the coil, then perform a thorough diagnostic to identify the root cause—whether it's a leak, a failing blower motor, or a dirty coil itself. We'll repair the issue and provide preventative maintenance advice to keep your system running efficiently.

We strongly recommend our bi-annual Precision Tune-Up, specifically tailored for the Las Vegas environment. This service includes cleaning the condenser and evaporator coils, checking refrigerant levels, calibrating the thermostat, cleaning drain lines, and inspecting electrical components. This proactive care is the best defense against the clogged filters and freeze-ups that plague local systems, saving you money on repairs and energy bills.
