Hot & Cool Heating and Air Conditioning is a Dallas HVAC contractor with a perfect 5.0 rating across 45 reviews — and Mauro Arredondo, the lead technician, is the consistent thread across nearly every one of them. This is an owner-operator-style business where one person has built genuine personal trust with dozens of customers through fast response, honest pricing, and dependable follow-through.

The review pattern is consistent and specific: Mauro is called for emergencies in both extreme heat and freezing cold, and he shows up within hours. One customer describes Mauro arriving within two hours of the initial call. Another describes a winter heating failure during the coldest stretch of the season — Mauro came out and resolved it. A third describes calling twice in different seasons, each time with the same fast, efficient result. Multiple customers mention that they've become loyal repeat clients specifically because of Mauro's reliability.

Alongside technical performance, customers specifically note Mauro's trustworthiness when letting someone into their home — a concern that comes up in reviews and reflects the personal relationship customers build with a solo or small-team operation. Pricing is described as reasonable and fair, without the upsell pressure some customers associate with larger HVAC companies.

Hot & Cool operates Monday through Saturday with standard business hours (closed Sunday), which means they're not a 24/7 emergency contractor — but for Dallas homeowners who want a highly reliable, honest technician they can call for both planned maintenance and urgent repairs during business hours, Mauro and Hot & Cool are a strong option.
