I hired iHummingbird to install 6 new iprotect units from Nest in my townhouse in Florida. I did my research on this product so I was familiar with how it works. They are easy to operate. The installation was very good and it took about 2.5 hours. I chose this company because they have guaranteed service and are affiliated with Nest so I knew they would be good. I had a time limit to get it done by and they were fast at scheduling. However, iHummingbird is more expensive than other installation companies. The installation was not a very difficult job, but they charge $125/hr. If I had more time, I would have used a cheaper installation company, but I would still recommend iHummingbird due to their great service.
