Customer Testimonials

One of your employees came to perform the yearly inspection of my furnace. He was a polite, efficient, hard-working individual. He pointed out some future problems and answered all my questions without hesitation. You should be proud of this individual.

– Eugene D., Livonia, MI

Both my wife and I were very much impressed by the courtesy and professionalism that your service technician displayed. After thoroughly inspecting the heating system he explained the problems with the furnace. He told me what my options would be and gave me a good estimate of how much the repairs would cost…and he did everything he could to complete the repairs as soon as possible. Because of employees like this, should I need any furnace or A/C repairs in the future, D&G will be the first company that I contact.

– Donald B., Farmington Hills, MI

I wanted to thank one of your employees for going above and beyond the call of duty. He came to our house to perform the spring cleaning on our air conditioning unit… and noticed that we had an exposed electrical outlet…he created a temporary cover for it until we could get it fixed. You should be proud to have an employee who goes the extra mile for your company and its customers.

– Barbara B., Novi, MI

I appreciate you helping me have "peace of mind." I love D&G – whenever anyone asks me I will always refer them to you.

– Phyllis L.

I would like to thank you for sending me a very efficient worker. He was kind and did his job well.
