Common HVAC Repair Issues
HVAC problems can surface in many forms—and we’ve seen (and fixed) them all. At Proton Mechanical, our experienced technicians are trained to diagnose problems quickly and implement long-lasting solutions.
Common Repair Issues We Handle:
No Heat or Cooling – We work to quickly identify the root cause, whether it’s a faulty thermostat, compressor failure, or electrical issue, and restore your system’s performance.
Leaking or Low Refrigerant – Our team locates leaks, seals them, and recharges refrigerant to restore proper cooling.
Blower or Fan Malfunctions – We repair or replace motors and fan components to ensure proper airflow.
Electrical Failures – From tripped breakers to capacitor issues, we safely resolve electrical faults that can cause system shutdowns.
Strange Noises or Odors – We track down the source—whether it’s loose components, burning wires, or mold buildup—and fix it at the source.
No matter the issue, our goal is the same: restore comfort, protect your equipment, and get your system running reliably again.
HVAC breakdowns can disrupt your operations, impact tenant comfort, and even pose safety risks. Whether it’s the middle of winter or the peak of summer, Proton Mechanical is here when your system stops working.
