O&N Cooling n' Heating

O&N Cooling n' Heating operates as a fully licensed HVAC contractor serving the greater Houston metropolitan area, including neighborhoods throughout Harris County. Founded by Orlando Quintana, a state-registered technician, the company has accumulated 26 verified five-star reviews, a perfect rating that reflects consistent delivery on its stated mission of customer satisfaction. Both residential homeowners and commercial property managers rely on this team for installations, repairs, and preventive maintenance across all major AC brands. The company maintains direct communication between customers and field technicians, bypassing dispatch middlemen to ensure technical questions reach knowledgeable professionals immediately.

This contractor distinguishes itself through key partnerships and transparent business practices. As a recognized Liberty Home Guard Partner, O&N qualifies for approved warranty work through that network while maintaining independence from any single equipment manufacturer. Their service menu includes ultraviolet germicidal system installation, an increasingly popular upgrade that targets airborne pathogens while improving overall system efficiency. The company explicitly promises competitive pricing with willingness to improve any written estimate, and their online representation guarantees zero hidden charges, a commitment that reads as a direct response to common homeowner frustrations with the industry.

Customer testimonials consistently highlight Orlando Quintana's diagnostic precision and customer-first approach. When Saundraea Colburn's AC produced unusual noise, Orlando inspected both units despite initial uncertainty about whether the sound indicated real malfunction, ultimately discovering a minor mis-contact that could have escalated into costly repair. He declined to upsell unnecessary services. For Robert and Megan Nichols, Orlando arrived with a new fan motor and compressor ready for installation, answering every question while sharing longevity tips that homeowners rarely receive. Maureen Diemer received same-day service when her thermostat failed during a period of intense summer heat, a scenario where delayed response carries real health risk. These accounts establish a pattern: technical competence paired with honest communication.
