"AMAZING customer service!! My a/c went out this weekend - yes, THIS weekend the hottest weekend of the year. I called the office and they were able to have a service technician out within 5 hours. The truck was a sight for hot and sore eyes for sure. He did a wonderful job finding and fixing the problem as quickly as possible. 10/10 highly recommend!!"

"Our Sunday started with the air-conditioner not cooling our home. Monday same thing but not sure if it just couldnt keep up with the high temps. Tuesday decided to call Hartmans heating & Air Conditioning Very. Busy but said they would send a tec out on Thursday. Tec came we talked and he went to work to find the problem, We need a new start up switch , it was installed and after all his checking he gave us a smile and said we are back with the air conditioning working,, We have been with Hartmans for many years and are always so grateful, thankful for their help. Give them a calll."
