Hello David and Patricia,

My sincere apologies for the delay in sending you this letter.

Your staff did some work for us (in August), and you send us a Survey Sheet.

Bruce & Paulette D. , Vacaville
Good people. Good service. Good products.

John. A, Sacramento, CA
The quality of a new heating and air conditioning system is not based on the equipment that comes inside of the cardboard boxes - it is based on the people who sell it, install it and service it. So there is no higher quality system than the one that comes from Greiner.

Stacy W., Davis, CA
The workers did a very good job. Alex handled everything from beginning to the end very professionally.

Thank you

George W., Fairfield, CA
All the men were professionals. They were polite, efficient and friendly.

P.S. thanks roger for the gift coupon (Starbucks).

Martha Y., Davis, CA
You have great employees - they're friendly and genuine and knowledgeable. That fact that they have great camaraderie and like working for Greiner says a lot. I also appreciate the honesty and forthrightness displayed without being pressure to buy "up" or beyond what was reasonable/expected.

Wendy S., Woodland, CA
Great service and competitive prices. Thanks for the Starbucks card. We are warm and toasty with our new heating system.
