Contacted Scottsdale Air and Heating for an estimate. They said someone would get back to me but when they hadn't after four days I called again. They connected me to Steve V who set a day to come out and give me an estimate. Steve came and I discussed that I needed the duct work moved in my single level two HVAC zone house. Both zones cooled the main room and the thermostats were in the main hall on opposite ends. I stated I wanted to separate the house into two zones with one HVAC unit cooling the the master bed/bath and spare bed/bath. Steve told me that the issue was I had to small a unit for my house and that I needed to spend $17,000.00 to install an entire new system. He also told me that how I wanted the duct work laid in the attic was not possible due to the construction of the house. Steve verbally quoted me the 17 K and said he would send a formal email quote in a few days. I asked him to also quote me with my request about moving the ducts and the thermostat. Three weeks passed and I never received the quote. I call Steve on the his cell and asked if he sent the quote and he states he hadn't had time to get around to it but said I'd have it in a few days. Quote never came and by then I had a second contractor give me an estimate. The house was custom build and we had purchased it a few months prior, the previous owners had larger than needed HVAC installed to accommodate a possible future addition. The home inspector also stated at the time of purchase that the HVAC units were more than adequate. We contact another HVAC contract (see other post) who came out to give us an estimate. They apologized on behalf of Scottsdale Air and Heat and said we had more compacity than we needed and that the thermostat and some duct work needed to be added, rerouted/relocated to optimize the systems. They did the job and the units work amazing now. Scottsdale Air obviously only wants the work if they can get a high dollar bill. I would assume many others have fallen victim to this company.
