Never ever try to contact TANU Refrigeration for purchasing or repairing. I have bought Blue Start from this shop with Stabilizer in May 2014. The stabilizer is showing low output voltage. When i contacted TANU Refrigeration. They said that they will come and check it as it is in service warranty period.But later on, he started arguing and did not come for service till now even after 1 week. When they installed the AC, they did not give the PLUG also. So, i need to put the wires directly into socket which can be dangerous sometimes. Really pissed of with this TANU Refrigeration, NOIDA.
