Centra Air Conditioning & Heating of L.I. | Top-Rated HVAC Services in Smithtown, NY

Boiler pressure drops are common here, often due to a leak in the system or a failing pressure relief valve. First, check for visible water around the boiler or radiators. If safe, you can try repressurizing the system using the filling loop, but if the pressure continues to drop, it indicates a leak that needs professional attention. At Centra, we perform a thorough inspection to locate the source—be it a corroded pipe or faulty valve—and provide a permanent repair to restore safe, efficient operation.

Yes, refrigerant leaks are a frequent culprit for poor cooling on Long Island. Signs include reduced airflow, ice on the coils, or a hissing sound. Refrigerant doesn't get 'used up'; a low level means there's a leak. It's crucial to have a certified technician like ours at Centra find and seal the leak before recharging the system. Simply adding refrigerant without fixing the leak is illegal, wasteful, and will lead to the same problem recurring.

Emergency signs include no heat in winter, no cooling in a heatwave, strange burning smells, loud banging from the boiler, or water leaking from the AC unit. These require immediate attention to prevent safety hazards or major damage. For routine maintenance—like reduced efficiency, minor noises, or seasonal check-ups—scheduling a service visit is perfect. At Centra, we offer 24/7 emergency service for Smithtown residents because we know how quickly comfort and safety can become urgent local issues.
