JM HVAC: Best HVAC Services Serving Petaluma, CA 94952

Yes, poor cooling is a classic sign of a refrigerant leak, a common issue in Petaluma's older AC systems. At JM HVAC, we first perform a thorough diagnostic to locate the exact source of the leak. We then repair the leak, evacuate the system, and recharge it with the precise amount of refrigerant specified by the manufacturer. We never just 'top off' the refrigerant, as this is a temporary fix that can damage your compressor. Our repair ensures optimal efficiency and cooling performance.

Rattling, squealing, or grinding noises from your air handler often point to fan motor or blower wheel issues—another frequent repair we see locally. Our technicians will inspect the fan assembly for worn bearings, a loose blower wheel, or a failing motor. We'll clean any debris causing imbalance and either repair or replace the faulty components with high-quality parts. Addressing these noises promptly prevents further damage and restores quiet, efficient airflow throughout your home.

We recommend bi-annual maintenance—once in spring for your AC and once in fall for your heater. Our preventative tune-up includes checking refrigerant levels and pressures to spot early signs of leaks, cleaning the condenser and evaporator coils, lubricating fan motors, tightening electrical connections, and inspecting the entire air handler assembly. This proactive service helps catch small problems before they lead to costly breakdowns, improves energy efficiency, and extends the life of your system in our local climate.
