Portland Air Conditioning and Heating Service
Bradshaw’s is a Certified DEQ shop and we follow strict guidelines for evacuating and recharging AC systems. Before we can recharge the system we have to identify refrigerant type and evacuate the AC system. We put the system under vacuum and confirm that there are no leaks. If the system holds then we can recharge the AC system. If the system does not hold under vacuum we will confirm where the leak is and get you an estimate for repairing AC leak and recharging AC system.
