I have already recommend the A/C tune up to my co-workers! We had Choates come do a check on our aging A/C unit. The tech was very nice, called ahead like they said he would & met me at the house. After he finished checking filter, cleaned the unit & checked the freon he gave us our report. The best part ....he did not try to sell us anything extra!!! We will use them again for sure! Thanks Choates for providing a no pressure service.
