I have no other experience to compare.
A friend of my has recommended this company.
They changed two HVAC systems in my house. Installation was done with no issues.
Staff are friendly, answered to all my questions (why this?, what is this?)
I have only one concern They did not change the pipes to the A/C. These pipes are 18 years old. Maybe it is ok. I don't know.
Also I can't say about prices, because I did not compare.
