I hired On Time Home Services to replace both the air conditioning system and the furnace in my home. The office staff was friendly and I had no trouble making an appointment. The day of the appointment, the technicians arrived promptly. They were very respectful of my property and very polite. They were very professional. They left the area very clean. The technicians were very knowledgeable. I was very satisfied with the work performed by On Time Home Services, and I highly recommend them.
