I have used C & J Air Conditioning and Heating Co.for over 20 years and I have been most pleased with them. They are a pretty darn good company! They are always on time, and they are very professional. Their customer service is great, and they make sure to let me know when it is time to perform the twice yearly service on the unit. On top of that, they are very efficient. They get here, and they start right into the work, and get it done. Like I said above, they are a pretty darn good company!
