I would be very cautious about engaging with this vendor. They seem to be going through some significant growing pains these past few years. We spent hundreds of thousands of dollars with Alliance on HVAC installation and maintenance. Yet, we could not get reliable post-service installation. For example, for our latest issue with our heating system, it took two weeks to get a technician dispatched who actually understood how to troubleshoot and diagnose the type of system that we have here (heat pumps). During this two week period, the heat kept failing in our main building guest rooms every night. A second example: A few years ago, Alliance installed an NTI furnace in one of our buildings. That furnace has failed many times over the past few years, most recently due to the combustion chamber being full of water. According to NTI, this problem results from improper servicing (clogged condensate or improper combustion settings). These types of issues are supposed to be dealt with through annual servicing. Although we were under an active maintenance contract for all of our equipment (and for which we paid a significant fee each quarter), the issues were not detected nor resolved until we had a complete failure in the boiler, requiring replacement of the combustion chamber. When we addressed our concerns with Alliance, the President of Alliance informed us they no longer wished to do business with us, and to seek support elsewhere. In summary, it seems that Alliance is happy to take your money to install the equipment (and for quarterly maintenance!) but they are reticent to stand behind their work or properly service the equipment you paid them for. Proceed cautiously!
