The day Titan came, the technician was very nice and prepared. He went in and before I knew it, he was done. I went in after they were done and saw all the holes and gaps blocked like they said they would. They were so pleasant from the first phone call to the service. I am happy with my attic now being rodent proofed!
Showed up on time. Took their time to guide us through the process. Performed his work in a professional manner, and explained all further steps. Don’t hesitate, nothing but a great experience with them .

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.

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.

We called Bright Nest Insulation after enduring another sweltering summer with an AC that couldn't keep up. Their team identified that our attic insulation was not only inadequate but also improperly installed in areas. They completely redid the work with precision and care. The crew was professional, efficient, and left everything immaculate. The comfort level in our home has improved exponentially, and our energy bills are finally under control. Exceptional service and results.
Choosing Bright Nest was one of the best investments we've made in our home. The process was seamless, and the results speak for themselves. The crew was efficient, worked together like a well-oiled machine, and left the worksite spotless. They focused on the science of building performance, not just laying down material. Our heating system no longer cycles on and off constantly, and the overall ambiance of our home is just more comfortable. Top-notch professionalism.

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.
Choosing Clear Price was a stress-free decision. Their entire process is built around transparency. The price was clear, the timeline was clear, and the crew's work was clear in its quality. They arrived as scheduled, installed a deep, even layer of insulation, and cleaned up thoroughly. Our energy bills have started to reflect the upgrade, and we know exactly what we paid for. For honest service at a clear price, call them.
Outstanding service from a company that values honesty. Clear Price Attic Insulation gave us a straightforward, competitive price and stuck to it. There were no surprises or last-minute add-ons. The installation team was efficient, clean, and respectful of our home. The difference in our upstairs temperature is already dramatic, and we're confident we got a great value. For anyone tired of confusing estimates, this is the refreshingly clear alternative.

I recently had Atticare come out to clean and insulate both my attic and crawlspace, and I can’t say enough good things about the experience! Sean was my technician — super friendly, on time, and clearly knew his stuff. He showed me photos before and after, explained everything in plain English, and made sure I understood exactly what was being done.
I recently had Atticare come out to my house last year to remove old insulation and then lay down new insulation along with rodent proofing the attic. A little over a year later Rats were still getting into my Attic and even though my warranty had expired Attic care was nice enough to send out their engineer Kyle to address the issue. Kyle spent several hours at my house today to do a thorough inspection and rodent proofing of any access areas were the rats might be getting into my attic. Kyle also repaired my air ducts the rats were chewing, cleaned up the attic of any droppings and completely sanitized. Very happy with the follow up work Kyle was able to complete today.
I recently used Atticare for my home in Pasadena, and I can honestly say it was one of the best home service experiences I’ve ever had. The team showed up right on time, explained the process in detail, and got to work right away. They removed the old insulation, cleaned and sanitized the attic, and installed fresh insulation that made my home feel instantly more comfortable. What impressed me most was how thorough and professional they were. They didn’t just do the job—they also sealed entry points and made sure my attic was protected for the long term. It’s such a relief to know my home is cleaner, safer, and more energy efficient. I highly recommend Atticare 5 stars all the way!

I cannot say enough good things about this company. We’re new homeowners and they took the time to educate us and give us very fair quotes. They were prompt, honest and super thorough with their work. The owner was personally texting us updates and sending photos throughout the entire process. Would definitely recommend this place to anyone getting insulation or air duct replacement! Amazing value for sure!
My experience with Pure Eco was outstanding, I was able to get my attic done in 1 day of work with a quick, courteous, very professional crew by Armando. I didn’t replace my air ducts since I moved into my house 12 years ago, I lost air flow and the layout was horribly messy, they need to be changed , it was the original ducts system, I had noticeable temperature differences in most of the rooms around my house after we checked the attic we noticed that there is no insulation at all but roofing debris. I am very pleased with the ending results. Thank you Armando for making that happen!
I would highly recommend Pure Eco for any house insulation projects. We had really old insulation in our attic that hadn't been replaced since we moved in a few years ago. We were also affected by the Eaton fire so we were concerned about any potential ash and debris that may or may not have escaped our initial inspector's notice after the fire. Many thanks to Beni and his meticulous handling of this job. He came out to provide an estimate on a Monday and had us scheduled for our insulation to be removed, cleaned, and replaced with new, eco-friendly material by the next Tuesday (mind you, it was 4th of July weekend as well so timing might've been even quicker if not for that). Shout out to Andres, Romeo and Anthony for the amazing job they did for my family's home. They came exactly on time at 8 AM and went straight to work. No dilly-dallying, just straight up efficiency. They were pleasant and professional to speak with throughout the day. By 3pm they were done and left the house clean. Amazing experience, highly highly recommend.

We’ve always had amazing experiences with Total Comfort, and yesterday was no exception! Their technician, Ricardo, came out and quickly resolved our heater issue. He was incredibly professional, super attentive, and just an all-around great guy. You can tell he genuinely cares about his work and making sure everything is perfect. Highly recommend Total Comfort—Amazing Customer Service!
Total Comfort came to my house (via my new home build warranty). After explaining issue to the tech Ricardo, he quickly got up in the attic, diagnosed, fixed the problem and explained what he had to do. It seemed like only a few minutes and he was gone. I wouldn’t hesitate using Total Comfort again, even after warranty expires with builder . Thanks again to total comfort and my tech Ricardo.
Ricardo showed up to perform a warranty repair on the heater on my new home. He was able to identify and repair the issue on the spot, and corrected a wiring issue left by the contractor who performed the original install. He was efficient, professional, and skilled at his job.

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
