Excellent Team
“NEXTGEN repaired my HVAC system which had an intermittent heating problem on a timely basis and it was covered under warranty. The technician was very polite an professional.”- Mark R. -
Can't Say Enough Good Things
“My thermostat took a dive on me so I went to replace it. That's where I met Breanna at Home Depot she advised me on the Ecobee one and normally I don't use big companies because of cost is always higher since they have higher overhead. However, at $49 for a diagnostic they sent someone out and that's when things got even better Lazaro was our technician. He was trustworthy and communicative and effective at explaining to me and my wife what he's doing to our unit and why. In the end because of his demeanor and character I chose to get work done through his company. I got an ionizer placed and he patched a few areas where air was escaping. Cleaned condenser and added a second capacitor and cleaned the fan on inside of my house as well as checked the coils which were fine. In summary the company is trustworthy or at least my experience was good. At at a $49 diagnostic fee it was worth it to have someone come out and let me know where I'm at. Can't say enough though about Lazaro he sold me on trusting next gen so if everyone is like him you'll find value.”- S.S. -
Trustworthy Team
“My technician Joseph was a solid and upstanding dude. He took his time doing an inspection of my old hvac system. He let me hover over him and helped educate me on the different components of the furnace and AC units. He didn’t tell me what I wanted to hear, but he told me what I needed to hear. Would trust him and his team to do my maintenance and future installs for my home.”- Andrew W. -
Great Service!
“My AC stopped working and gave me a power failure message. Ryan was dispatched as the technician to assist. He was great, he quickly diagnosed the issues (fuses and capacitors). He gave me practical solutions and was great to work with. If I have issues in the future I will be asking for him specifically.”- Roger D. -
Appreciate the Team
“Gabe was so efficient and explained everything so we could understand. He took his time to thoroughly look at all of our concerns and figure out some type of solution. I appreciate his taking the time with us!”- Carly N. -
Went Above & Beyond
“Ryan was extremely professional and knowledgeable. He took the time to thoroughly explain everything in a clear, detailed way, which I genuinely appreciated. He was clean, respectful of our space, and very thorough in his work. You can tell he takes pride in what he does. He went above and beyond, and his kindness and professionalism did not go unnoticed. Highly recommend.”- Erika A.
