Sterling Services came out last week when our AC went out and it was 100+ degree weather. They offered to come out that night at no extra charge or the next morning whichever was convenient for us. When the repairman came out, he was very nice and fixed the unit quickly. The price was very affordable, too. I would definitely recommend Sterling Services. Also, the office personnel were great. I have had some less than desirable experiences in the past with other companies and working with them was great!
