Blackstone Heating & Air Conditioning: Experienced HVAC Services Serving New Rochelle 10801

Common signs of a refrigerant leak include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, and a noticeable hissing or bubbling sound. Your system will also run constantly without effectively cooling your home, leading to higher energy bills. If you notice these issues, it's best to call us for a professional diagnosis and repair to prevent further damage and restore efficient cooling.

Uneven heating, often with cold spots in certain rooms, is typically caused by an imbalance in your radiator system. This can happen due to trapped air (which requires bleeding the radiators), sludge buildup in the pipes, or incorrect pressure settings from the boiler. Our technicians perform a thorough system evaluation to identify the root cause—whether it's air, water flow, or pressure—and re-balance your radiators to deliver consistent, comfortable heat to every part of your New Rochelle home.

Repairing a refrigerant leak is a precise process. First, our certified technician will locate the exact source of the leak using specialized electronic detectors or ultraviolet dye. Once found, we repair the compromised section of tubing, coil, or connection. Finally, we evacuate the system to remove any moisture and air, then recharge it with the correct type and amount of EPA-approved refrigerant. This restores your unit's cooling capacity, efficiency, and lifespan, ensuring it runs reliably for our New Rochelle climate.
