Hi, i have a box airconditioner i need installed. It is replacing an existing unit but the new unit is bigger and requires bricks and plaster to be cut bigger. The electical work is already done, it has a 20amp separate citcuit already setup. It is just a matter of installation. I had another company quote for the work and turning up tomorrow, they have now let me down. I dont have another day off for 2 weeks, so i need this done tomorrow if possible.
