We arrived at our vacation home in Sun City, AZ, to our air conditioning not working, inside home temp was 90 degrees at 5pm. Our home warranty company referred us to Lee Collins Air Conditioning and we were in touch with them immediately. They walked us thru things that would help and they gave us excellent tips. They stayed in touch and in a few days we had a brand new unit. They were so helpful and always right there. We would highly recommend this company!
