Absolute Comfort Cooling & Heating

Hired them 3 years ago for air conditioning upgrade. It took 2 days but not sure why, Paid for a years coil cleaning. Thought they would call to make an appointment but they didn't. Tried calling them for over 2 years to come out to clean the coils. Didn't get an answer until recently. Charged full price for the service. I asked to have least some of the money applied to the bill from the earlier service. They said no. I asked if they knew why no one called to come out and no one had an answer, Will not ever use them again.
