I got a phone call on Monday March 17, 2014 from a guy named Donovan for a tune up on my air conditioning unit. Donovan was very informative and polite so I scheduled a tune up from Hoffman Refrigeration to come out the next day. The service technician named Will came out and he did an excellent job. I will be recommending this company to all of my friends and family members. I checked their rating on Better Business Bureau and now I know why they have a A+. I was very impressed with this company! They do a great job and all their staff is very professional.
