BUYER BEWARE!!!! Do not use this company!!!!! I spent $29,000 to have these people install two geothermal systems in my home. Both systems have had a total of three ground tap failures causing both systems to lose all refrigerant leaving me without heating and air conditioning. It is nearly impossible to get the owner of the company to return phone calls. When he finally does return a phone call he plays dumb like he doesn't know what the problem is, but never offers a solution. I've had to abandon the geothermal system and go back to a conventional type system. This company does not honor their warranties. The owner also eluded to having financial problems. Their salesperson and driller have jumped ship because of the owners unethical behavior with customers. I'll be taking legal action against this company.
