Before any work begins, always clarify in writing what the job entails and what the cost will be. To protect yourself against fraud, read customer reviews and verify that your HVAC cleaning service has applicable licenses and certifications.
"So My A.C. suddenly went belly up and I needed a total brand new unit inside and out. So a little background on myself. I'm an engineer, so I know a little bit about A.C. and how they work. I'm by no means an expert, but it does allow me to detect if the A.C. guy knows his stuff, especially if they don't know what I do. 😉 And I'm happy to say, these guys do. One of the things that helped me chose them is that they brought up the importance of controlling humidity. None of the other contractors I spoke to, mentioned that. I also appreciate the fact that he didn't try to "up sell" me and get me to buy things I didn't need. He was on time, honest and forth coming about what I needed and what I didn't. When the workers came, they were on time, very professional and very CLEAN. After they left, I couldn't tell they had been there. Highly recommended this service."
