"Harmond helped me over video link to test the components in my broken refrigerator. The testing confirmed that it was the compressor that had failed. I purchased a new refrigerator because I decided it was not worth the cost to replace the compressor."

"This was the 1st time using this G-septic as the other company we have used in the past appears to not be in business anymore. Was thoroughly impressed by the services we received, we had them pump our tank and after they finished they noticed my main pipe entering the tank was cracked. They were able to not only let us know of the need for a repair but gave us a price to fix it. He dug out the trench and quickly fixed it at a very very reasonable price. Super pleased, had a great conversation with Edgar the owner while he was onsite turns out this man who looks to be in his late 20's has been doing this work for 20 years and boy you can tell, he is so knowledgeable, sure glad we stumbled upon him when we Google searched septic pumpers."
