Customer Testimonials
Margaret T. — Old Towne Orange, Attic Blown-In Insulation
I was shocked at how drafty our 1960s home was, even with the windows replaced. Thermal Nest came out, assessed the attic, and recommended blown-in insulation to fill in all the gaps. The crew was punctual, respectful of our home, and finished the job in one day. Within the first week we noticed our HVAC wasn’t running nearly as long. Absolutely worth every penny — I only wish we’d done it sooner.
Carlos R. — Serrano Heights, Spray Foam Insulation
We built an addition on our home and needed spray foam insulation done right the first time. Thermal Nest gave us a detailed written quote, explained exactly what closed-cell foam would do for us, and completed the work ahead of schedule. The inspector had zero complaints, which says a lot. Their team cleaned up the workspace completely before they left, something I really appreciated. Hands down the best contractor experience I’ve had in Orange.
Linda & Steve M. — Chapman Hills, Crawl Space Insulation
Our crawl space was a mess — old, deteriorating insulation that was doing nothing for us anymore. Thermal Nest removed it all, treated for moisture issues, and installed new vapor barrier and insulation properly. They sent photos throughout the process so we could see exactly what was happening under our house. The price was fair and matched the quote exactly. Our floors feel warmer and we’re already seeing lower gas bills this winter.
James O. — Villa Park Adjacent, Wall Insulation Retrofit
I contacted three insulation companies in Orange and Thermal Nest stood out immediately because they actually explained why I needed what they were recommending. The wall insulation retrofit was minimally invasive — small holes, quick patching, no mess left behind. Communication was excellent from the first call through the final walkthrough. I’ve already recommended them to two neighbors on my street. Don’t waste time shopping around — these are your people.
Priya S. — East Orange, Attic Air Sealing and Insulation
I called Thermal Nest after seeing my summer electric bills climbing every year despite having central AC. They did a full attic inspection and found significant air leakage around recessed lights and duct penetrations. The combined air sealing and insulation upgrade made an immediate difference — my July bill dropped by over $80 compared to last year. The technicians were knowledgeable and didn’t talk down to me when I asked questions. This is a company that truly knows their craft.
Tom W. — Fletcher Hills Area, New Construction Insulation
Thermal Nest handled all the insulation work on a new guest house we built behind our main property. They coordinated seamlessly with our general contractor, hit every scheduling deadline, and passed all inspections on the first try. The foreman walked me through all the R-value choices and building code requirements so I understood what I was getting. Their pricing was competitive and completely transparent. I’ll be using them again for our garage conversion project next spring.
Rachel K. — Orange Park Acres, Garage Insulation
We converted our garage into a home gym and needed it properly insulated before finishing the walls. Thermal Nest recommended the right combination of batt and rigid foam for our specific situation. They worked around our schedule, showed up when they said they would, and finished the job cleanly. The space is now comfortable year-round, which in Orange summers is saying something. Really glad I chose a local company that knows the climate here.

Our Ratings Across Review Platforms
Thermal Nest Insulation of Orange maintains a 4.9-star rating on Google with over 100 verified reviews, a strong presence on Yelp with consistently high marks, and full accreditation through the Better Business Bureau. These ratings aren’t accumulated passively — they reflect real projects completed for real Orange homeowners who took the time to share their experience.
When choosing an insulation contractor in Orange, verified third-party reviews matter enormously. Unlike testimonials posted directly on a company’s website, Google and Yelp reviews are from authenticated accounts and cannot be edited by the business. Look for patterns across reviews: Are crews consistently on time? Do final costs match quoted prices? Are problems resolved quickly when they arise?
BBB accreditation adds another layer of accountability, requiring businesses to meet standards for transparency, advertising honesty, and complaint resolution. When a contractor scores well across all three platforms, that’s a strong signal you’re working with a company that stands behind its work every time.
