AC repair in Richardson, Texas
Richardson lies west of Garland. Its Building Inspection department handles mechanical permits online, and it moved to newer code editions than Garland uses.
Mechanical permits go online
Richardson lets contractors buy permits for mechanical, electrical, plumbing and gas repairs or replacements through its online permit system. The city says most of these permits require a licensed contractor to obtain the permit and do the work, and a contractor needs a current Richardson registration to open an account.
In practice, a Richardson AC replacement usually starts with the contractor buying the permit online, which is quick only if their registration with the city is current. Ask about it on the first call.
