- TESTIMONIALS
What Dallas Homeowners And Businesses Say About Citywide
"AC went out at 9 PM on a Friday in August. Called Citywide and a tech was at my house by 11. He diagnosed a failed capacitor, had the part on his truck, fixed it in 20 minutes. Quoted me $11 on the phone & that's exactly.”
"Three HVAC companies told me I needed a full system replacement. Citywide diagnosed a refrigerant leak and a dirty coil. Repaired for [fraction of replacement cost]. The technician even showed me the readings.”
"Signed up for their maintenance plan after the technician explained what he found during the tune-up — two things that would have failed within the season. Fixed them during the maintenance visit.”
