To put my review in context, I know more about heat pumps than 99.9% of consumers (likely more than some professionals)... Barrington is an experienced and responsive HVAC tech, and he is a pleasure to have around when your HVAC system needs some work. When I called to tell him that my heat pump had failed, he offered to come around the same day as he thought I had lost heat in the middle of December (I did have backup heat installed in the system, but it shows his thoughtfulness). I'm not going to say he'll be able to wave a wand and fix everything first time, that's not realistic for anyone. However over the past 6 years, Barrington has done two pieces of work for me diagnosing & fixing the issues correctly both times. Thus, the 5 stars on my review apply to both jobs. Based on the jobs he's done for me, I trust him to do a good job at a fair price. The company name is "Affordable HVAC Service", it is not "Cheap HVAC service", but I don't want cheap, I want fair priced - the HVAC tech has to earn a living too! Barrington will be my go to guy for any future problems or improvements, and I recommend him for yours.
