Not sure who they are paying to write these other reviews, but this company seriously overcharges, knowing full well that they have you right where they want you: pay what they say or lose your service fee, which you'll have to pay again to the next company that tries to overcharge you. $573/hour for labour in my case. The London HVAC racket is clearly thriving. We need laws to protect us against this kind of company. Don't believe the Google reviews or the ones on their site. Look instead at all the complaints and the people they buy off on the BBB site. I fell for the 700+ positive Google reviews - don't be another victim like me.
