A & J Heating & Air Conditioning | Reliable HVAC Repair in New Port Richey, FL

Yes, a sudden loss of cooling is a classic sign of a refrigerant leak, which is common in our Florida heat. At A & J, we first perform a thorough inspection using electronic leak detectors to locate the source. We then repair the leak, which could be at a connection, coil, or line, and evacuate the system before recharging it to the manufacturer's exact specification. This ensures your system cools efficiently again and protects the compressor from damage.

That humming sound is a telltale sign of a failed start capacitor, a very common electrical failure in New Port Richey due to frequent power cycles and heat. We prioritize these emergency calls because your system is completely down. Our technicians carry a wide range of capacitors on their trucks and can typically diagnose and replace the faulty part on the same day, restoring your cooling quickly and safely.

Great question. Electrical issues, like a bad capacitor or contactor, often cause the system to not start at all, trip the breaker, or make unusual humming/buzzing noises. Refrigerant problems usually manifest as reduced cooling performance, ice on coils, or hissing sounds. As your local experts, we're skilled at diagnosing both. We'll clearly explain what we find, whether it's an electrical component needing replacement or a leak requiring repair, so you understand exactly what's needed to fix your comfort.
