Mr Gilmer was very polite and patiently explained the issues with our air conditioning unit. He provided us with options and did not pressure us into making immediate decisions that could cost thousands of dollars.
Mr Gilmer was very courteous and helpful. He explained the problems with my system. He took photographs of what was not working and compared them with the new part so that I could verify the need for the part. I was pleased with the service I received and would use his services again.
Can’t say enough positive things about Josh and the customer care he provided. He answered all of my questions and took the time to explain in detail how everything worked with our system. Overall we’re happy with the service he provided and will use him again in the future!
Mr. Gilmer went above and beyond during the service of our AC unit. He took his time and answered all questions. Simply put he was terrific!
Mr Gilmer was fantastic. A lot of help in replacing the pieces necessary and getting our thermostat fixed. A great employee and a delight to talk with.
