Vlad (owner of GTC) is very good & professional. Used him on 3 separate occasions - (1) replace heater. It went out on Dec 31, 2015 !!! Vlad came out in the evening, to see if it could be repaired on the spot, and then cam back first thing on Jan 2nd ( when the supplier opened so that he could replace the unit). Did everything cleanly! Reasonable price -
even considering he came out on holiday. ( I tried to use ABC Heating emergency - quoted me $8000 or 2.3 times more - tried to use my desperate situation) . Anyways, Vlad did it better and reasonably priced! (2) Also used Vlad to replace my 10 year old AC. No problems, as expected. (3) Asked Vlad to come out and help with installing Nest thermostat. It's not difficult to do on your own - but wiring to the old unit looked messed up - and I didn't want to take a chance. Vlad cleaned and rewired it and helped me install the unit.
