DNS Heating & Cooling, LLC | Reliable HVAC Repair in Shelton, CT

Yes, a refrigerant leak is a common cause of an AC blowing warm air, especially in older systems. For Shelton homeowners, this issue often worsens during our humid summers. Our technicians use specialized tools to locate the leak, repair it, and recharge your system with the correct amount of refrigerant. We prioritize these calls to restore your cooling as quickly as possible, typically within the same day for emergency service calls.

Signs include unusual grinding or humming noises from your indoor unit, weak airflow from your vents, or the fan not turning on at all. This is often an urgent repair for Shelton residents because a failed fan stops your entire HVAC system from heating or cooling your home. We can diagnose the issue—whether it's a faulty motor, capacitor, or bearing—and perform the necessary repair promptly to prevent further discomfort or potential damage to your system.

The best defense is proactive maintenance. We recommend a professional tune-up for your AC in the spring and your heating system in the fall. During these visits, we check refrigerant levels, inspect electrical connections, clean coils, lubricate moving parts, and test the air handler fan. This routine care can catch small issues before they become major repairs, improve efficiency to lower your energy bills, and extend the life of your equipment in our Connecticut climate.
