I bought a Groupon, knowing it probably wouldn't cover what I needed since we've been in our house since it was built in 2001. However, I figured it was a good place to start and it would get me to finally do it. Isaac called ahead of time and said he would be at my house in 30 min and he was on time, on the dot. He did tell us our ducts needed more attention than what the Groupon covered (which I was expecting). He deducted the price by the amount of the Groupon and we ended up paying $360. I think the best thing about this initial cleaning is that now I can have Isaac come yearly for only $49. If we sell our house I think this is a big plus. We've had dogs and cats since we've lived here and we live in the Vail/Tucson area (very dusty). Thank you Isaac!
