Came out earlier than I booked which worked out for us. The guy was very friendly and was happy to educate while doing the servicing of our unit. He was very polite and cleaned up after himself.

They got here on time and the technician was outstanding. Would definitely recommend them. I retired from a heating and air conditioning company and Kiefer is way above them in service and price!
