Welcome, first thing would be which passport you hold, U.K. or eu
Regarding working in air conditioning, I was a refrigeration and air conditioning engineer for 40 years before retiring, our U.K. qualifications are not recognised so you would need to gain the equivalent qualification to carry out the work, the electrical requirements in Spain are also different so that is something else you would need to obtain.
If you only have a U.K. passport then you would need to find someone to sponsor your job application and apply for a visa but any available jobs have to be offered to eu members first.
