Knight & Day Heating Service: Certified HVAC Repair Serving Patchogue 11772

Yes, refrigerant leaks are a common issue in our area, often caused by corrosion or vibration over time. We start with electronic leak detection to pinpoint the exact location. Once found, we repair the leak, perform a thorough vacuum and pressure test to ensure it's sealed, and then recharge the system with the precise amount of refrigerant specified by the manufacturer. This restores cooling power and efficiency, protecting your compressor from damage.

This is a classic heating imbalance often due to air trapped in the system or valves that need adjustment. Our service involves 'balancing' your radiators. We bleed the system to remove air pockets and then adjust the lockshield valves on each radiator to control the flow of hot water. This ensures heat is distributed evenly from room to room, eliminating those cold spots and improving overall comfort and fuel efficiency.

Our preventative maintenance is key to avoiding issues like leaks and inefficiency. We perform a comprehensive check that includes inspecting refrigerant lines for early signs of wear, checking pressure levels, cleaning coils to maintain airflow, calibrating thermostats, and tightening all electrical connections. For heating, we test system pressure and inspect boilers and radiators. This proactive approach helps catch small problems before they become major repairs, saving you money and hassle.
