“Mr. Thompson recognized the urgency of the situation and made great effort to resolve the matter as quickly as possible. His professional, thorough, and honest appraisal of the working condition of my AC lead to minor repairs that resulted in SIGNIFICANT savings when compared to the quotes of the BRAND NAME outfits! Thanks for your commitment to integrity and a job well done 👍🏼!!”
