Recent Review: I bought the range hood at Home Depot and was told that it could easily be installed by their installers. The installers came out, realized that it was not being hooked into an existing venting system and told us they did not know how to do it. (They charged us $50.00 to tell us that.) Subsequently, the same installers then contacted my sister (I was out of country) and told her they would come out and they would be able to install it. Once again, they came out and decided they really didn't know how to install it and charged us another $50.00 (note--When my sister notified Home Depot of the situation, Home Depot was mortified and removed all charges) However, for almost 9 months I had no vent for the range and could not use it. Finally, I was told by a friend that it would probably take an HVAC company to install it (I had been searching appliance and electrical companies). I used Angie's List and found Mitchell Mechanical and saw the number of glowing reviews. I contacted them and within the week one of their employees was at my home and provided an estimate. The day of the installation arrived and Andrew and William arrived at exactly the scheduled time, in fact they called to let me know they were on the way. They were extremely polite, professional and efficient. I could not have hoped for better service. They did everything that was promised, cleaned up after the job and tested both the vent and the range to make sure all were in proper working order. The cost and time that it took was exactly what they estimated. I highly recommend this company. In fact while they were here I signed a contact for the company to check my HVAC twice a year. It was a very lucky thing that I did because they found a broken flue pipe. I have contracted with them to come and do all the repairs.
