They've done multiple services for us at different locations. They've done residential and commercial. My businesses' air conditioner went out and when it was 105 degrees and I called Nicol Climate Control on a Saturday, they came right away and got it back up and running. When we opened up our second location, they were there from the beginning to the end to make sure all the air conditioning needs were met. Nicol Climate Control is always on time, very prompt, and they were within the budget that we wanted. We are completely satisfied with them.
