We're here to help people — not just fix AC units.
At NexAir, giving back is part of who we are. We recently hosted a community back-to-school drive to support local families across the DFW area — providing school supplies to kids who needed them most before the new school year kicked off.
We believe a strong community starts with neighbors looking out for each other. When you choose NexAir, you're supporting a local, Texas-owned business that reinvests in the people and neighborhoods we serve every single day.

Great communication and very professional. Technician Noel Cruz was very helpful in providing solution options to address the problems after he finished the assessment of the unit. Will definitely recommend contacting NexAir.

Cruz was very professional coming into our home to fix our ac. He is very knowledgeable and we felt secure in his recommendations. He was very fast and friendly in his replies and with our questions. Truly a great experience and most importantly our ac is fixed in this Dallas heat!
