Customer Testimonials
Maria G. — Floral Park, Attic Insulation Replacement
After years of sky-high electricity bills, I finally called Thermal Nest Insulation of Santa Ana to assess my attic. The technician arrived on time, explained everything clearly, and gave me a written quote that matched the final invoice exactly. The crew completed the attic insulation replacement in a single day and left my home spotless. My energy bills dropped noticeably within the first month — I only wish I had called sooner.
James T. — Downtown Santa Ana, Spray Foam Insulation
I own an older craftsman home near downtown and had serious drafts coming through the walls every winter. Thermal Nest recommended closed-cell spray foam insulation and walked me through why it was the best solution for my home’s structure. The installation was fast, professional, and completely transformed the comfort of my living room. I’m genuinely impressed by how thorough and knowledgeable this team is.
Rosa M. — South Coast Metro Area, Blown-In Insulation
We hired Thermal Nest to add blown-in insulation to our attic after noticing our upstairs rooms were unbearably hot every summer. From the initial estimate to the finished job, everything was smooth and stress-free. The crew was respectful of our home and took extra care to protect our belongings before starting work. Our upstairs now stays noticeably cooler and we’ve seen real savings on our cooling costs.
David L. — Lacy Neighborhood, Wall Insulation Upgrade
Thermal Nest Insulation came highly recommended by a neighbor, and they absolutely lived up to the praise. They helped us understand our wall insulation options without any high-pressure sales tactics, which I really appreciated. The installation team was efficient, courteous, and cleaned up everything before they left. This is a company that clearly takes pride in doing the job right the first time.
Angela P. — Riverview West, New Construction Insulation
We were building an accessory dwelling unit in our backyard and needed a reliable insulation contractor to work alongside our general contractor. Thermal Nest coordinated perfectly with the rest of our construction team and completed the insulation on schedule. Their product knowledge helped us choose a solution that maximized our energy efficiency within our budget. I would not hesitate to recommend them to anyone building or renovating in Santa Ana.
Carlos R. — Willard Neighborhood, Crawl Space Insulation
I had no idea my crawl space was the source of so much of my home’s heat loss until Thermal Nest did a full assessment. They explained the problem, showed me photos, and gave me a fair quote with no hidden fees. The crew completed the crawl space insulation in half a day and the difference was immediately obvious. This company is honest, skilled, and genuinely cares about the results they deliver.
Linda S. — French Park, Attic Air Sealing and Insulation
Thermal Nest Insulation did a fantastic job air sealing and re-insulating my attic in my historic French Park home. They were sensitive to the age of my property and took extra precautions to protect the original structure. Communication throughout the project was excellent — I always knew what was happening and why. The finished work is clean, effective, and I can already feel the difference in how evenly my home heats and cools.
