Billy from GreenPro Cleaning cleaned our entire heating system today and I couldn’t be happier. We’re living in a rental and were pretty certain the system hasn’t been cleaned in at least 30 years (or even EVER.) Let’s just say what we found was shocking. Some of our vents were completely blocked. It was disgusting. And to think that we’ve been breathing this in for years. Billy was wonderful in explaining the entire process, spraying for possible dust mites, and letting us know what really did and didn’t need to pay for. We will 100% be using GreenPro again for our AC units and any additional work we may need done. Highly recommend. We’re looking forward to breathing clean air!
