Desert HVAC maintenance guide for extreme summer heat

Homeowners in desert regions, such as Phoenix and Las Vegas, face unique challenges regarding air conditioning maintenance due to extreme temperatures, dust storms, and monsoon humidity. Prolonged use during summer months can reveal underlying mechanical issues that may not have been apparent earlier in the season.

Key indicators of HVAC system strain include increased run times to reach thermostat settings, reduced airflow, and new or unusual noises such as rattling, humming, or clicking. Environmental factors like airborne grit from dust storms can clog condenser fins and air filters, while high humidity can impact efficiency. Proactive maintenance is recommended to manage energy costs and ensure system reliability during periods of intense heat.
