Is the AC broken in your companies warehouse?
If the air conditioning has stopped working in your companies warehouse be sure to hire the right company for the next commercial AC installation job. The last thing you want is to hire an HVAC company that is not experienced in commercial HVAC work. Some heating and cooling contractors only perform residential jobs. These type of companies are the last companies you want working on your warehouses heating and cooling system. Not only will they not have the experience you are looking for, but there is also a good chance they will not be certified as well.
So, when you realize that it is indeed time for a new mini-split HVAC system, be sure to do some research on the company you are thinking about hiring first. If they do not have proof of certification and previous work performed on warehouses I highly suggest finding someone else.
