Air Conditioning, Refrigeration & Heating Repair
We understand the importance of attending site when a failure has occurred, especially when mission critical or people rely on it. We will arrive on site promptly and when we say we will be there. We have experienced engineers all over the home counties ready to attend your site. We are normally able to diagnose a fault within a couple of hours on site, however if parts are required once the problem is known we will furnish you with a fixed price quotation to allow you to decide if you wish to proceed with the repair giving you total control over your own budget.
All parts fitted carry a 12-month warranty as standard.
