Superior HVAC fixed an issue with our air conditioner that was blowing warm air. The technician replaced a failed capacitor and the system was cooling properly before he left

The furnace would start but shut down after a few minutes. The technician replaced a faulty limit switch and confirmed everything was operating safely
