Cool/Hot Guys AC is a Scottsdale-based HVAC company with a 4.8-star rating across 108 reviews, operating 24 hours a day across Scottsdale, Phoenix, Chandler, Mesa, Gilbert, Tempe, Queen Creek, Paradise Valley, Fountain Hills, and Cave Creek. The company handles residential and commercial HVAC repair, replacement, maintenance, and smart thermostat installation — with a team that earns repeat business from landlords, homeowners, and commercial clients alike.

Named technician Joe is highlighted for his technical knowledge and personal character — Seth Assar described finding a genuinely excellent AC serviceman and expressing gratitude for the experience, emphasizing how difficult it is to find competent service and how Joe exceeded expectations. Andy Demetriou has used the company for years across multiple rental units, describing consistent quality across a range of jobs from Freon refills to more complex work, and citing it as the reason they keep coming back.

The company's front-end operations are also praised: Allison Salcido noted the owner's availability for questions and the efficiency of the heat pump installation crew. Darrius specifically praised the call center staff as accommodating, caring, and very customer-focused — an unusual mention that reflects a company that invests in the full service experience, not just field quality.
