Your HVAC contractor will definitely need to be licensed in your state. Licensing is an important component of this whole process that often gets overlooked. HVAC work requires someone to go through a significant level of training and education. This means that HVAC work is heavily regulated by nearly every state and local government out there. An unlicensed HVAC contractor can wreak havoc on your home if you are not careful. Your local building inspector will be able to give you a list of necessary licenses that all contractors should have.

Only hire contractors with experience. There are a lot of things that can go wrong when you are dealing with wall heaters. A lack of experience can lead an HVAC contractor to make poor decisions when he or she is installing the wall heater. Due to the nuanced nature of this work, it is always important to consider the importance of experience in this work.

Get a quote from your contractor before you hire him or her. The quote will give you an idea of how much you can expect to pay once the job is completed. It will also give you a frame of reference when you are deciding what contractor to go with.

Always hire contractors that have a high level of insurance. Work like this presents a number of opportunities for contractors to accidentally cause damage to your home. If the contractor is insured, then you will be protected if an accident does occur.
