When it comes to hiring HVAC technicians to see to your home’s heating and cooling needs, there are a few signs of quality for which to look. You should never turn to amateurs for a job this important, but what actually sets an amateur apart from a professional?
One thing to look for is certification. A quality HVAC technician will have NATE certification (North American Technical Excellence), which is an industry-recognized certification of knowledge of the field. However, you should also look for technicians who have gone a further step and received EPA certification.
