The one at the Oasis shopping area is very good.
They are on the back road behind the Arches cafe bar.

Would not recommend Homecomforts.es - British guy.
I booked him to do a service on our air-con in 2 apartments on a recommendation from a friend.
Failed to turm up to 2 appointments when I'd driven 40 minutes to get there.
Also charges at least double what the Spanish guys do.
