D&T Refrigeration Corp: Experienced HVAC Services Serving Jamaica, NY 11434

Signs include uneven heating/cooling between rooms, higher-than-usual energy bills, and excessive dust. In Jamaica's older homes, ducts can settle, loosen at seams, or get damaged over time, creating leaks that reduce airflow and strain your system. Our technicians perform pressure tests to locate leaks and use professional-grade sealants to restore efficiency and comfort.

Short cycling is often caused by an oversized unit, a dirty air filter, a faulty thermostat, or issues with the flame sensor or heat exchanger. It's a frequent issue here that wastes energy and can lead to premature system failure. D&T's diagnostic service identifies the exact cause—whether it needs a simple cleaning, recalibration, or component repair—to protect your system and lower your bills.

Our preventive maintenance includes inspecting and sealing accessible duct connections, cleaning coils and blower components, checking refrigerant levels, calibrating the thermostat, and testing safety controls. This proactive service is designed to catch small problems—like developing duct leaks or causes of short cycling—before they become major repairs, ensuring your Jamaica home stays comfortable year-round.
