Derick was great he showed us how if, we cleaned our blower motor, in our 4 year old home that it would be more efficient and save on energy. - He cleaned it! Derek also explained how this new air filter would help with our allergies . . . sold! . . . the air filter system that has already made a big differance in both of our allergies. Derick did an awesome job! The only down side to everthing was that our appointment was 6 weeks late due to the hot weather. But Golden Rule did take care of this on our bill. We thank you for all the work you all do to, help us and insure that everything is running correctly. Thank you Derick and Golen Rule. Keep up the great work.
