"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"The professionalism and quality that the Insulation Labs team demonstrated from beginning to end should serve as a Master Class for any other service oriented company. Scheduling the estimate was effortless with clear, helpful and efficient communication from Diana, their first line of contact. Abraham arrived to do the estimate visit with kind patience and knowledge. He took the time to help us figure out how best to approach the insulation and was more than willing to answer all of our many questions. When we received the estimate we were appreciative of how easy it was to read and understand what the plan was. We knew exactly what to expect and how much it would cost. Today was the day of the insulation. Chris, Tzoc, and Moises spent a long full day doing the entire job. Throughout they were kind, professional, and did an outstanding, neat job. At all times, they cared for our space as if it were their's. We are so glad we chose Insulation Lab. There is no question we would recommend them to anybody."

"I hired Attic master to come over and check the attic for some bad smell. Adam came over to my house and went up to the attic and checked the problem there... He recommended me to remove the old insulation and to place a new one. His price and warranty were good... so i hired them. The following morning, he came over with his worker and took out all the old insulation while his worker placing the new one. The work was completed the same day and the problem of the bed smell has been solved."

"We had no problem or issue with this company. They came and did exactly what they said and promised. The service was fast too. We were able to schedule them for the same week and the work was completed after 2 days of work. According to the technician that worked at our house, it was better to use the opportunity when the attic empty from the old insulation and to replace the ducts as well. For the price that we were able to got, we decided to do that too.
so overall, we are in the stage that we will use this company in the future and we will refer them to people that we know and might need the same kind of work to be done.

"These guys saved us during the recent heatwave. I looked for days for someone to come help us service our airconditioner, which was working....except for the cold air part. These guys were so easy to get in touch with and they put us on the schedule for the next day. They took a look and the fix was really easy. They serviced the AC, made some recommendations for future upgrades (but made sure to let us know they weren't emergencies) and left us with a house full of cold air. It was one of the easiest home services we've had in our new house. HIGHLY RECOMMEND."

"GC Heating and Cooling put in a 3 zone furnace and AC system for our 3100 sq ft house in Manhattan Beach back in 2018. We recently had an issue due to the unprecedented heat wave and Gustavo and Jordan fixed the issue under short notice. You can always expect quality work and great service from them."

"Mario is an amazing technician! He came to my home on time, was professional, courteous, and knowledgeable. The visit was only for a maintenance of my heating and AC unit, but Mario noticed some concerns with my insulation. He took an immense amount of time to explain to me the entire process of how they will clean out and replace the insulation. I was extremely satisfied with the service provided. Mario really embodies the core values of Home Comfort and went out of his way to make sure that I was comfortable with the plans being made and that I was happy. He also worked out an amazing deal for me on the insulation project. He is the best technician and I left feeling that I am a valued member of the Home Comfort family. Thank you, Mario!!!"

Insulation questions, answered by experts

In Orange, insulation success depends on selecting materials that resist heat, pests, and meet local fire safety standards. Proper air sealing and balanced attic ventilation are essential for energy efficiency and moisture control. Quality installation by experienced professionals familiar with local codes ensures long-term performance. Regularly inspecting for signs of moisture or pest intrusion helps maintain the effectiveness of your insulation service project.

Helpful?

For insulation service projects in Orange, start by booking a professional energy audit to identify areas with poor thermal performance, especially in attics and crawl spaces common to local homes. Check if permits or HOA approvals are required for your neighborhood. Choose attic insulation materials rated for high heat and low humidity, such as R-38. Apply for utility rebates early, and schedule work for spring or fall to avoid peak contractor demand.

Helpful?

New homeowners in Orange should prioritize upgrading attic insulation to at least R-38 for optimal thermal performance during hot summers. Next, seal and insulate ductwork, especially if it runs through unconditioned spaces. Add insulation to exposed pipes and water heaters to prevent heat loss. Weatherstrip windows and doors, focusing on areas with direct sun exposure. For older homes, assess wall insulation, particularly on west-facing walls, to improve overall energy efficiency.

Helpful?

In Orange, create a seasonal routine by inspecting attic insulation each spring for settling or rodent activity, and clearing soffit vents before hot weather arrives. During summer, use a thermal camera to spot insulation gaps and monitor attic temperatures. In fall, check for wind-driven debris after Santa Ana events. Winter is ideal for checking pipe insulation and identifying drafts, helping maintain energy efficiency and indoor comfort year-round.

Helpful?

When planning insulation service projects in Orange, consider CA’s strict energy efficiency and fire safety regulations, as well as possible permit and HOA requirements. Take advantage of local utility rebates and financing options. Opt for low-VOC, fire-resistant insulation materials to address air quality and wildfire risks. Plan around seasonal weather patterns like the marine layer and Santa Ana winds, and be aware that contractor availability may vary throughout the year.
