I would recommend NexGen when it comes to HVAC work in a heartbeat. Quotes are fair. They are super professional. They work fast!!! It was a quick two day job to replace our ducts and replace and install the HVAC system. They are amazing! Answered all our questions. Put our minds at ease. Walked us through everything. If anything was wrong they come right out and fixed it.

We just recently bought a house and wanted piece of mind knowing that our a/c was performing to its potential; especially during these record breaking heat. I was able to book next day service. The service delivered by Jay, was exceptional. He was respectful, professional and knowledgeable. He made me feel confident I called the right company for the job.
