Can a homeowner replace their own AC in Texas?

State licensing law does not apply to work on a building owned solely by you as your home. Your city may still require a permit, and El Paso only issues trade permits to licensed, registered contractors.

Can I replace my own AC in Texas?

The air conditioning and refrigeration licensing law does not apply to a person doing air conditioning and refrigeration contracting in a building owned solely by that person as the person's home (Occupations Code 1302.053). Your city can still require a permit and inspection. (source: Texas Legislature)

Sources differ. State licensing law exempts a property owner doing plumbing in their own homestead (Occupations Code 1301.051), a person doing air conditioning work in a building they own solely as their home (1302.053), and electrical work "not specifically regulated by a municipal ordinance" done in or on a dwelling by a person who owns and resides in it (1305.003(a)(6)). El Paso's homeowner affidavit says a homeowner may NOT obtain mechanical, electrical, plumbing, irrigation or fire systems permits unless licensed with the state and registered with the city, and that trade permits are only issued to state licensed contractors registered with the city (Ord. No. 18508). The state exemption is about licensing; the city controls its permits. Call El Paso Planning and Inspections before planning DIY trade work.

Refrigerant rules still apply to you. Federal law prohibits intentionally venting refrigerants while servicing or disposing of AC equipment. (source: U.S. Environmental Protection Agency)
