"Called at 3pm on a Saturday — the tech was at my door by 5pm. Diagnosed and repaired the low output issue quickly. Great service and great price."
"Hands down the best customer service I've received for any repair work. This team bent over backwards for us during urgent cooling issues at peak Texas summer. Very communicative and professional."
"They came out and replaced my old AC and furnace in August. Prompt, professional service — no sales pressure or gimmicks. Pricing was competitive and the installers showed up on time and did a quality job."
"During the pandemic our AC went out in the middle of a Texas summer. The staff helped me come up with an affordable plan and worked with me every step of the way. The people really are the backbone of this company."
"My tech Garrett was professional and on time — he even brought coffee on the morning of the install. The unit is functioning better than before. Very friendly and hard to find this level of service these days."
"Another company told me I needed a full new system. Air Heat North Texas came out quickly, repaired my existing AC for a very reasonable price, and I've never looked back."
"They were upfront with costs, honest, and professional when our AC system broke down completely. Would use them again without hesitation."
"Same-day service. Said they'd be there between noon and 1 — he was there at 11:55. Took care of everything and was gone before 12:30. Top notch, honest, and friendly."
"I've been a customer for a number of years. Very professional techs and great management. When a contractor problem took out our capacitor, they had the part in their truck and handled it immediately."
