Air Conditioning & Heating in Orange
When your AC or heater stops working, you need someone who shows up fast and fixes it right the first time. NEXGEN services every type of system — central air, ductless mini-splits, heat pumps, furnaces — and our technicians are trained to diagnose the real problem instead of just replacing parts. We offer honest repair-vs-replace advice, seasonal tune-ups that catch small issues before they become expensive ones, and installation backed by real warranties.
Signs Your AC or Heater Needs Attention
- Uneven heating or cooling from room to room
- Strange noises, rattling, or grinding sounds coming from the unit
- Higher-than-usual energy bills without a clear reason
- The system cycles on and off more frequently than it used to
- Weak airflow from vents throughout the house
Plumbing in Orange
From a slow leak to a full repipe, NEXGEN's plumbing team handles it all. We use camera inspections to find the source of a problem instead of guessing, and we're equipped for everything from water heater repair and installation to drain cleaning, sewer line repair, and gas line work. If it's an emergency, we're available around the clock.
What to Do in a Plumbing Emergency
- Shut off the water at the main valve or the fixture's local shutoff
- If it's your water heater, turn it off to prevent damage
- Use towels or buckets to contain any standing water
- Avoid running water or using drains until the issue is diagnosed
- Call NEXGEN right away — the sooner we're there, the less damage there tends to be

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.
