Dear Air Ref Family,
Thank you so much for attending to our new unit "problem" today. We appreciate your good service to us as customers. I think Jason is an excellent technician. I am sure you will want to hold onto him as a valuable employee! Enclosed is payment for the new Carrier system.
Although it's not listed on the invoice, we are assuming it does include the extra $1000.00 for the service contract/warranty? Thanks again for taking care of us.

Sincerely,
Frances Washburne
