I had called Reliable Comfort Inc. on a Friday, because a fan wasn't running in my air conditioning unit, so it was not working. They were flexible with scheduling my appointment, and came out the following day, on Saturday. They gave me a 30-minute courtesy call before arriving, and once they showed up, fixed the issue with my system. They were professional, respectful, and made sure to clean up after themselves. It was my first time using them, and I'm going to sign up for their semi-annual service check-up.
