Need pump installed however still without heat- tech was very professional however after speaking to his supervisor the only thing they were able to tell me was to call Con Edison- trouble shooting was not dont to fully understand the issue- I called Blend Air in Rockland NY and they are coming today to run some test to determine the root cause before reaching out to Con Ed if ready necessary- Dont understand why Yost could not run the same tests? Once again, still without the ability to heat my home and I had to contact another provider---not good---customer for 21 years!
