I'd used the same service company for 5 years. They'd somewhat recently been purchased by a larger player and had since become more sales-focused. Our last recommended service came with $4000 worth of "recommended work". I found Colony through the Carrier website. They had someone out the next day to provide a free "second opinion" service. Rene took the time to clean our outdoor unit more than the prior company had just a week prior. He also clarified that we likely didn't need the services that the other service had recommended. I think I'm ready to dump my old service!
