We wanted to upgrade our insulation during a remodeling project. The contractor recommended spray foam across the entire roofline. Home Star Insulation handled the installation, covering vaulted ceilings and tight areas.Everything was good and approved!!
Our home had patchy insulation throughout the walls and attic, especially around the kitchen and living room. We had Home Star Insulation come out for a full replacement. They worked from the attic floor to the high ceiling corners and even insulated above the recessed lighting cans. Highly recommend them for homes that need a full insulation overhaul.
Our attic hadn’t been touched in years, and the insulation was sagging and ineffective. Home Star Insulation removed everything, sealed air leaks, and installed new insulation along the roof beams and attic floor. They used quality materials and took the time to explain how each part of the project would help improve our home’s efficiency. It’s been a few months, and the difference in comfort and air quality is incredible.

Fast, clean, and super professional. You can tell they know what they’re doing. Definitely recommending them to friends.
We reached out to Thermal Nest after struggling for years with a perpetually hot second story in our Simi Valley home. Their assessment was incredibly thorough, and they proposed a solution that combined radiant barrier installation with enhanced attic ventilation and air sealing. The crew was professional, efficient, and left the worksite spotless. The difference is absolutely remarkable; our home now maintains a consistent, comfortable temperature throughout. They truly built us a better thermal nest.

I had Ram Insulation help with my attached garage project. They showed up on time with three-man crew and completed my 20' by 20' garage insulation within a day. They have done very nice and detail-oriented work and my garage looks brand new and ready for the next step.
Miguel and his team were referred to us by our HVAC vendor. We had them remove and replace the insulation in our home. Miguel, Adolfo and the crew were punctual and professional throughout the project. The entire project took 3 days and they did a great job of prepping our home, covering areas to protect and keep clean, removing the old insulation, and cleaning out any remaining debris before installing the new material. Adolfo took the time to explain what would happen during each part of the process including what things I can expect from having the work done. They were also good about the cleanup work when they finished. I already notice the difference in how much the new insulation is helping block out the heat inside my home. Hard working and dedicated crew. Would highly recommend using RAM for your home insulation needs.
Miguel’s team, Hector and Alfonso did an outstanding job of insulating our attic. They came bright and early and blew in insulation as well as laid rolls of insulation throughout our space. They were professional and courteous. They even had to deal with sharing space with a painting crew that was at our house to finish up a project. Super good folks and the insulation project was priced very competitively. Give Miguel a chance to bid for your business. You won’t regret it.

We hired Thermal Nest to solve the constant battle with temperature in our older San Diego home. Their approach was incredibly thorough—they didn't just add insulation, but performed a complete assessment that included air sealing and evaluating our attic ventilation. The crew was professional, efficient, and left the worksite immaculate. The difference is remarkable; our home now maintains a consistent, comfortable temperature naturally, with far less reliance on the HVAC system. They truly built us a better thermal nest.
I am thoroughly impressed with the quality of work and customer care.

I called Thermal Nest Insulation for a second opinion after another company quoted me an outrageous price for spray foam. Their estimator was refreshingly honest and explained that for our specific home and Santa Ana's climate, a combination of air sealing and high-density cellulose would achieve excellent results at a fraction of the cost. He showed me the R-value comparisons and let me decide without pressure. The installation was flawless, the crew cleaned up meticulously, and I saved over fifteen hundred dollars. Integrity like this is rare.
I am thoroughly impressed with the quality of work and customer care. Thermal Nest Insulation provided a tailored solution for our home with a complex, low-clearance attic. Their crew was skilled, patient, and ensured every single cavity was properly insulated and sealed. The before-and-after difference is night and day. Our home now retains warmth on cooler evenings and resists the daytime heat far more effectively. A trustworthy and highly skilled local company in Santa Ana.
Choosing Thermal Nest was one of the best investments we've made. The entire process was seamless, with excellent communication from start to finish. They addressed both our attic and crawl space with impressive professionalism. The crew worked diligently, protected our property, and cleaned up perfectly.

In November 2024, we hired Top Energy to install ductless mini-splits in two studio spaces and the garage on our property. Leor was very responsive and knowledgeable, and helped us determine the location and size of the systems. Installation was one day; pricing was fair. The crew even returned to do several other handyman projects, which went well. Adding climate systems to these rooms has been a game-changer in how we use the space. Highly recommend Top Energy!
When both of our AC units unexpectedly stopped blowing cold air Top Energy Solutions was able to get a tech out quickly to diagnose the problem. It was discovered our system had a leak in the lines running under a patio. Leor came up with a solution for us and the next day removed the old systems and installed 2 new systems. The crew was efficient, professional, and did quality work. Because of that we had Leor and his crew come back the next day and insulate the attic and install an attic fan. I couldn't be happier with the communication, efficiency, and professionalism of Leor and his crews!
Top Energy Solutions is the best contractor I have hired. Leor is responsive and professional. I acquired three quotes to have my HVAC system replaced. I accepted Leor’s quote, and the installation started, and was finished by the end of the next day - amazing. A crane was required to remove and replace the AC unit on a three story house. His installation crew was very friendly and very good natured. He beat the other quotes by more than two thousand dollars for the same equipment. Leor is a general contractor and has crews for most home repairs. I will be hiring Top Energy Solution again soon.

Great service.
Got three quotes for attic insulation and radiant barrier installation. Thermal Wrap was competitively priced but their knowledge set them apart. The estimator spent time explaining the science behind radiant heat transfer and why reflective barriers work differently than mass insulation. Installation crew was efficient and left zero mess. Our home stays cooler all day and the AC actually cycles off now. Great experience from start to finish.
These experts are in a league of their own. We built a new home and wanted the highest performance possible, so we had Thermal Wrap Insulation seal and insulate all of our exterior walls and roof before the drywall went up. Their attention to detail was remarkable—creating a continuous thermal barrier with no gaps. Now that we live here, the difference is astounding. The house is silent, draft-free, and unbelievably efficient. This is next-level building science applied perfectly.

Living in a historic Compton home meant dealing with high energy bills and uneven temperatures. After careful research, we chose Compton Insulation Pros, and it was the best decision for our home. Their holistic approach—air sealing before insulating—is what sets them apart. Our home is now draft-free, and our HVAC system runs efficiently. The team was punctual, polite, and extremely proficient. I cannot recommend them highly enough.
Exceptional quality from a local business. The office staff was helpful and responsive, and the field crew was phenomenal. They took time to explain the insulation options and helped us choose the best solution for our budget and goals. The installation was flawless, and our home feels like a new, well-sealed envelope. I've already referred them to family. A truly reliable and expert company you can trust.
The level of detail and care this company provides is remarkable. They didn't just add insulation to the attic; they meticulously sealed every wire penetration, plumbing stack, and gap in the top plates first—the critical step that many skip. Our home's ""building envelope"" is now truly sealed. The comfort improvement is immediate and profound. Thank you for your honesty and fantastic workmanship!

Had Clear Price out for attic insulation and the name is no gimmick. They actually give you a clear price. The estimator spent time in my attic, took photos, and explained exactly what needed to be done and why. The quote was itemized and easy to understand. Installation day the crew was punctual and respectful. They air-sealed every gap and blew in a beautiful even layer. My energy bill is down and I didn't pay a dime more than expected. Refreshing.

This company is highly professional. They are punctual, professional, and efficient in their work.

They arrived bright and early and got to work. They were done in one day! They cleaned out the old insulation and removed trash we didn't even know was in the attic before putting in new insulation.

Omar and his team are incredible! They installed a complete new HVAC system in my 1950’s ranch style home. Prompt, communicative and professional. I would recommend them to anyone looking for a complete installation or just a tune up. Worth every penny for the peace of mind!! Thank you Omar!
The company really cares that their employees do an all around excellent job. I previously used Service All-Stars to replace my heater. Now they have installed my A/C unit. They do excellent work.The techs were friendly and informative about the details of the work they were doing. I appreciate the fact the workers worked quietly and efficiently. The owner is receptive to constructive criticism which is a big plus in my book. I will continue to call upon Service All-Stars for my HVAC needs.
The team that Sal sent (Brandon and Evan) did a fantastic job on repiping my 60 year old house here in Long Beach. I found a leak in my tankless water heater closet and called them out to take a look. My house has a slab foundation and turns the leak was coming in from the main-line under the soil and then through the concrete to the water heater closet in the middle of the house. They dug down through the concrete and rather than just asking the guys to patch the galvanized pipes, I figured it best to do a full house re-pipe through my tight attic since the plumbing is 60 years old. Good thing because in the process, another leak was detected in the wall between my bathroom vanities. The guys were friendly and hard-working, the process took 4-5 days and I was informed of where they would have to cut through the walls to connect all the pipes. They definitley routed the pipes in the least invasive way. They also tuned up my HVAC system and tankless water heater while they were here. I would highly recommend Service All-Stars for your plumbing and HVAC needs. -DC
