I have used Allen's many times and always found them friendly, competent and efficient. They saved me on a hot June day in 2009. At 10:30 am I noticed my air conditioning was not cooling. I called it in and got ready for company that was expected in an hour. A serviceman was there by 1:00 pm and diagnosed my compressor had gone out. I left on a planned trip by 2:30 and the compressor was in and my house cool for my inside pets by 6:00 pm. Thank you so much.
