Geller Service

Geller Service installed my heating and air conditioning units in May 2009. I have had nothing by problems since! The air conditioner compressor went out and Geller told me he couldn't fix it because it was so heavy and he didn't do that anyone. No other information. Other service person told me that the installer should repair warranty items!!! I was totally flabbergasted. Geller just walked away and got in his van. The air conditioner is four years old. I have made nearly seven service calls on the heater and air conditioner since installation. Geller added sealant to the air conditioner in May 2013. Did that cause the compressor to fail? DON'T USE THIS SERVICE!!!
