Do Not Use “Six” HVAC
“Fool me once, shame on me.”
“Fool me twice, shame on Six.”
I am writing this from our home in Hamilton, NJ to prevent any other family from enduring the financial and emotional distress we have suffered since 2022. If you are considering hiring “Six” for your heating or cooling needs in Princeton, Hamilton, Lawrenceville, Robbinsville, or anywhere in Mercer County, please read our story first.

The Track Record: A Trail of Damage
Three years. Multiple disasters. Zero accountability.
He managed to flood both my basement and my attic. Yes, really.
The Flooded Basement — $4,900 Pump Replacement
After charging $4,900 to replace a baseboard heater pump at our Hamilton, NJ home, Six left only for us to find our basement completely flooded that same night. The cause? A misaligned gasket he failed to check.
The Destroyed Nursery — $10,000 AC Replacement
We made the mistake of giving him a second chance for a full AC replacement ($10,000). During the install, he broke the electrical in our bedroom closets (which still don't work to this day).
He left twice claiming the system worked — both times it shut off and would not restart. His employee had to come out two separate times to diagnose the problem and get it to stay on.
The day after that, water poured from the ceiling of our newly refinished nursery. The ceiling, carpets, and lighting fixtures were destroyed.
The Disappearing Act
When our home was flooding, Six didn't show up. He sent a “helper” who admitted the entire install was a “disaster” and spent the day fixing basic errors. It took six months of chasing Six — calling, texting, begging him to come back — while our two infant daughters were forced out of their room. And when the repair finally happened, it was not a simple fix. The ceiling, walls, sheetrock, paint, moulding all had to be redone.
When I tried reaching out about the emergency — water literally pouring from my ceiling — his wife attempted to guilt trip me for calling it urgent, because Six was sick. She went as far as sending me unsolicited photos of him in a hospital bed hooked up to IVs. It was extremely uncomfortable and completely inappropriate. I will not share those photos out of respect for his privacy, but it does not change the fact that my home was being destroyed by his work.
After that, he never returned another call. He also never provided the 1-year complimentary checkup he “included” with the install.
He was supposed to return after a few days with the warranty information, a final itemized bill, and an efficiency report. None of that ever happened.
All the paperwork disappeared with him.
The Situation Right Now
- •It is currently 82 degrees.
- •Our “new” $10,000 AC unit is completely dead.
- •Six is still nowhere to be found since the last incident.
- •He is not answering calls or texts.
- •He has failed to provide any warranty documentation for the equipment we paid for.

“Shoddy work. Overpriced. Keep him away from your home. Six had to return repeatedly to fix my new furnace because he didn't bother to check why it had stopped running the first time, though he was the one who installed it. He just started it up again and left, even though that shouldn't happen with a brand new furnace. … He overcharged me and tried to charge me double for something that is legally covered because it was his own work. I've had to find a competent professional to fix it. Learn from my mistake. Don't call Six.”
Rebecca B.
“Six has a really high number of 5 star reviews, but some of those are identical to each other. … He pads his prices and fudges the value you're getting. He also flat out charged me for something that should be covered under his own warranty. He lied to me multiple times to avoid work. He installed a whole new system — heat pump, oil furnace, electrostatic air filter, bypass humidifier. He had to come back repeatedly to get the system to work.”
David S.
“Horrible service. Made us overpay. Unit is still not performing as designed. Totally unprofessional and unprepared.”
