I have used A1 Cooling for 4 years now.. We own two homes and I have never had a problem. They have always been responsive and prompt. I have called in the Summer time when it was 100 degrees out and they would send someone right away. When I called about my moms air conditioning and told them she was on oxygen they never hesitated to be there. Their prices have been very reasonable. As a result of there excellence in service I have referred them to my neighbors and friends all who have been very satisfied. I would definitely recommend this company to you.
