We were also able to use the NYSERDA loan program (3.49% interest rate for 15 years) to pay for the cost of the energy efficiency aspects of the project AND receive a rebate through the Clean Heat program.

Terrible! Stay away from this company!! On May 2,2022, I had a scheduled a/c checkup, which was…read morepart of my yearly a/c and heating coverage agreement. They canceled the appointment because it was drizzling outside. Jessica, who contacted me to cancel the appointment told me that someone would get in touch with me within 2-3 days. So, someone should have called to reschedule by May 5. This never happened!! On May 8, I reached out on their company website without any response. On May 9, 2022, I called and got transferred to their answering service. Again, there was no call back! I did the same outreach the next day and Wednesday May 11,2022. I had also written an email to the owner , Mike on May 10,2022. There were a total of 5 outreach attempts without a response, only leaving my cell number for them to call back. Finally, I was fed up with their lack of responsiveness to my calls and e-mails. When I left my third phone message today with their answering service, I told the receptionist that if I didn't get a call back today that I would be writing a negative review and I would be taking them to small claims court to get half of my contract money ( $543 ) returned to me. Only today did I finally get a call back from the owner Mike. He was nasty, when he should have been apologetic to me. He told me that he's dropping me as a customer. He said he was going to come to my home , which I took as an implied threat to me and my family. He also lied to me and told me that he contacted me 5 times. This is a blatant lie as I just spent the last few hours checking my phone records for my mobile phone and landline. He only called back after I threatened to take him to court for breach of contract, which seemed to be what he was doing by avoiding calling me back and providing the services that I paid for in my yearly contract. I strongly urge anyone considering doing business with this company to seek another alternative. He is a nasty owner and can not be trusted. It is virtually impossible to reach anyone by phone and they certainly don't value their customers. I told him that I would give home 3 days from today to return half of my contract money. I don't expect that he will do this. So, I will likely be seeing him court in the near future!! I'd like to give ZERO stars, but apparently I can't do it !!
