My air conditioner was not working so I called Barrus Heating And Air. They sent their service tech out and he arrived promptly and on time. He worked on the problem but apparently it was a pretty complex issue. He called for additional help and they sent a second service tech out and they stayed until they had the problem fixed. I really appreciate their dedication to making sure that the unit was functioning properly before they left! They are a very professional company and their employees know what they are doing!
