Called these guys on Wednesday afternoon, they showed up exactly at 8 am on Thursday and give me a quote. I phoned up a few other shops for quotes and these guys were about even par, maybe just a bit more, but I was not able to compare like for like exactly. I gave them the go ahead and they showed up Friday morning at 8 am once again on time to start work. The old system was out and the new one was in place working in about 5 hours total. Really impressed with these guys, they even touched up some paint on the ceiling without me even mentioning it. They were clean, quick and despite being young in age fairly knowledgeable. I was really impress with the punctuality most of all, and they seem to stock a large inventory so they had a complete unit within a day. The guys were polite as well. I’ve had the unit for a few months now and it runs great and the electric bills are lower.
