Reading a listing
Two things on a listing tell you what the licence allows. The class sets the size of equipment: Class A for any size, Class B for cooling systems of 25 tons and under and heating systems of 1.5 million BTU per hour and under.
The endorsement sets the kind of work. Environmental Air Conditioning is comfort cooling and heating for homes and buildings. The Combined endorsement also covers commercial refrigeration and process cooling or heating.
The county is the one declared on the licence. The state registry holds no street address and no phone number, so neither appears here. Check the licence with TDLR and ask for proof of insurance before you hire.
