- Serving Houston Southwest and surrounding Areas
1CoolAir AC & Heating is a licensed, insured, and bonded HVAC company proudly serving Southwest Houston and surrounding areas. For over 15 years, we have been the trusted name for residential and commercial clients who demand reliable, honest, and high-quality heating and cooling services.
Founded by Lazard Dominique, our company was built on one simple belief: every family and business deserves to feel comfortable in their own space without overpaying or dealing with unreliable contractors. Today, that belief continues to guide everything we do – from a simple filter change to a complete system installation.
Lazard Dominique isn’t just the owner – he’s the standard. With over 15 years of hands-on experience in the HVAC industry, Lazard personally oversees every major installation and repair. He believes that the best marketing is a job done right the first time, with transparency, respect, and old-fashioned work ethic.
Lazard is available for direct consultations and emergency calls, because at 1CoolAir, we never hide behind voicemail or automated systems. When you call (346) 302-5275, you’re talking to people who care – often Lazard himself.
