Dallas Air Conditioning and Heating Solutions (also known as Crest HVAC) is a Dallas HVAC contractor with extended daily hours — 6 AM to 10 PM weekdays and 8 AM to 8 PM weekends — providing broad coverage for both planned and urgent service calls. With a 4.3 rating across 7 reviews, the company handles AC repair, heating service, and system diagnostics for residential customers across Dallas.

Reviews describe prompt response during high-heat emergencies, with one customer describing Crest arriving within hours of calling during a 100-degree-day AC failure. Technicians are noted for arriving early, resolving problems quickly, and treating customers personally rather than transactionally — one reviewer describes the experience as being treated like a friend. The company also handles HVAC inspection and improper installation diagnosis, with one customer discovering their prior AC installation was incorrect and having Crest properly reinstall the system.

The 4.3 average reflects a small review base with one negative incident involving a company vehicle (driver behavior complaint) rather than service quality. For Dallas homeowners who want extended-hours HVAC coverage with documented emergency response, Dallas Air Conditioning and Heating Solutions is worth contacting.
