Licensed HVAC Repair in Stamford, CT 06902 - Petro

Common signs of a refrigerant leak in your AC include the system blowing warm air, ice forming on the evaporator coils or refrigerant lines, a noticeable hissing or bubbling sound from the unit, and a sudden spike in your cooling bills. Since refrigerant is essential for the cooling process, a leak reduces efficiency and can cause compressor failure. If you notice any of these issues, it's best to call Petro for a professional diagnosis and repair to protect your system.

Thermostat malfunctions in Stamford can stem from dead batteries, dust accumulation, faulty wiring, or the unit being improperly leveled or located in a drafty spot. This can lead to uneven temperatures and system short-cycling. Petro's technicians will first check for simple fixes, like battery replacement or recalibration. If a replacement is needed, we can recommend and install a reliable model, including programmable or smart thermostats, to improve your comfort and energy efficiency.
