I definitely recommend Surrey Air Heating and cooling. They were able to send a technician at very short notice (<24 hrs) to fix my leaking Evaporative cooling. Mr Damon was very friendly, prompt, able to identify the problem quickly, took photos of the unit and clearly showed me the faulty areas.He advised me to contact Brivis directly as my cooler was still under Warranty to replace the faulty circuit board. I wish all the technicians are like Mr Damon!
