HVAC Services Fresno CA | Call Vezina Industries

Yes, a refrigerant leak is a very common cause of an AC blowing warm air, especially in our Fresno climate where systems work hard. Leaks reduce cooling power and strain the compressor. Our technicians use specialized tools to locate and repair the leak, then recharge your system to the manufacturer's exact specifications to restore efficient cooling.

Signs include reduced cooling, longer run times, higher energy bills, and ice forming on the coils. Fresno's dust and allergens can quickly coat the coil's fins, acting as insulation that prevents heat absorption. We perform thorough cleaning as part of our maintenance services to restore your system's efficiency and improve your home's air quality.

Regular professional maintenance is key. We recommend a pre-summer tune-up to check refrigerant levels, clean coils, and ensure all components are working properly. Changing your air filter monthly during high-use seasons also protects your system from dust buildup. Our maintenance plans are designed to catch small problems before they become major repairs in our demanding climate.
