Cold Temp Air & Heat (listed as Houston Air Conditioning & Heat on some platforms) is a Houston HVAC company owned and operated by Randall (Randy) Cary. The company holds a 4.9-star rating across 12 reviews. Randy is the primary technician and point of contact, personally handling service calls for both residential homeowners and investment property owners. The company operates Monday through Saturday with 24-hour service availability most days.

Randy's service approach is straightforward: fast response, affordable pricing, and personal accountability on every job. A friend referred a contact to Randy in the late afternoon; Randy's technician was on-site the next day and restored the AC. A 20-year-old HVAC system at a Spring rental property was replaced by Randy and his team in a single day — showing up as scheduled in the morning and completing the installation by evening.

Randy is a long-standing vendor in the Lifestyles Unlimited Real Estate Investor Club, which he notes is the source of the majority of his business — a strong signal of trust among Houston real estate investors who manage rental and investment portfolios. The company's reputation within that community reflects consistent reliability for property service needs.

On customer service, Randy documented absorbing a $1,000 loss rather than passing on the cost of a factory-damaged condenser to the customer — taking responsibility for a situation beyond his control because the customer was understandably upset. For Houston homeowners and real estate investors looking for a personally operated, affordable HVAC contractor with a straightforward approach, Cold Temp Air & Heat is a consistent option.
