I have Complete Comfort Heating and Cooling out twice a year to maintain my geothermal heating and cooling system. Josh is the one who comes out and he is such a gentleman! He explains everything that he does and he just gives me a good feeling about the system and it makes me feel comfortable that it will not go out or have problems when the weather is cold. For a young man, he is a great guy! My system is running well and I really appreciate their wonderful service!
