STAY AWAY!!! We have filed a compliant with the Better Business Bureau, the Consumer Protection Agency, and are now without any heating or air conditioning while we wait for a contract to fix, at our expense, the damage Hellotech did to our furnace and air conditioning. Not only did they break our system, but charged us for services they never did, are refusing to communicate with us, and now we are looking at hundreds of dollars in repair costs, and counting. Our doorbell and thermostat were working but we wanted to upgrade them to Nest products. We purchased Nest doorbell and thermostat and looked for an installer. Hellotech says they specialize in Nest products and are an authorized installer. We requested installation from them of the Nest thermostat and doorbell we had purchased. We were told they needed credit card information to confirm appointment, but we would not be charged until installation was complete and that we would be contacted by text with our appointment time and technician name. We received a message that our technician was Danny and he would come at 3 on Sunday, October 7, and a request to send a picture of the working areas. We sent pictures and Danny confirmed appointment by text for Sunday, October 7 to replace doorbell and thermostat. Danny arrived and took old doorbell off and then told us doorbell could not be installed without purchase of a transformer, which he did not have, and put doorbell back on. He then moved to thermostat and took off old thermostat and partially installed new thermostat. He then stopped and told us that we had a blown furnace fuse and thermostat could not be installed without a new fuse, which he did not have. He said we had an old system with old wiring and the fuse was not needed for the old thermostat but is needed for the new one. He left with the old thermostat removed, the new one partially installed, the entire system now non functioning, and promised to return the next day with the needed transformer for the doorbell and a fuse for the furnace, the parts needed to finish job. He also recommended we purchase a Nest door lock, which he said he would install the next day at a reduced cost and told us what to buy. We bought door lock that night as advised. Technician never returned or called and we called Hellotech. Hellotech representative told us that a different technician would come. New technician called to ask us what was needed to be done and told us he could not fix it. We called Hellotech and were then advised that Danny wrote in notes that we needed to hire, at our cost, an HVAC company to fix our furnace and he, Danny, could not install thermostat until that happened. We explained that the furnace and air conditioning worked well before Danny came and that if they could not install the new thermostat we wanted them to put the old one back and reminded them that we were now left without ANY heating or air or even the central fan and this was an urgent need. Hellotech said they would call a third technician to reinstall old thermostat. Third technician, Michael Wood, showed up on Tuesday, October 9. We told him what had happened so far and what Danny did in installing the thermostat. He asked if Danny had shut off power to the thermostat before removing it to install the new one. We said he did not and was actually testing throughout with his electrical meter and power was on throughout. Michael Wood then told us that Danny should have turned off power and that every technician turns off power before uninstalling the old thermostat and installing the new one, and if they do not they blow fuses and transformers. Michael Wood also said that if the company finds out what Danny did Danny will most likely lose his job, so it would be not be in Danny's best interest to admit he did not turn off power. Michael Wood said he would write a report and file it with the company so we could hire someone to fix our now broken system, likely needing a fuse a transformer and possibly more, and we should be reimbursed for our costs. Instead, company charged card for all installation services, including the door lock, installed nothing, broke furnace and refuses to do anything further. We tried contacting support based on Michael's recommendation. Support said they would look in to the matter, but instead of doing anything they have now ceased communication, are no longer responding to us. read more
