When I was preparing to purchase my house, I called several HVAC companies with good BBB ratings, but was told each time that they could not make it out to inspect the HVAC within my 10-day inspection window, until I called Cool Blew. The technician they sent is a licensed electrician and licensed HVAC tech. He did the electrical and HVAC inspections. They were thorough and gave me a list of electrical repairs that were needed. I negotiated a lower price to cover those repairs.
I have used Cool Blew for HVAC, Electrical and plumbing. All were A+ positive experiences.
For those poor folks that had 1-star experiences, I have a recommendation: Sign-up for their Preventative Maintenance program. You get priority scheduling and a discount on any needed parts.
