The Verdict
Clear Efficiency is a reliable pick for insulation and energy upgrades, but you'll trade some project-management polish for honest pricing and a crew who actually knows what they're doing. We analyzed nearly a hundred reviews and found two patterns that separate this company from typical contractors. First, they prevent expensive mistakes. One homeowner was told by three other companies to replace their entire HVAC system for $12,000 to fix hot spots, Clear Efficiency diagnosed it as missing insulation and charged a fraction of the cost. Second, their crews consistently deliver tactile results. In one case, a homeowner left their AC off all weekend in summer heat and returned to a cool house, something that would have been impossible before Clear Efficiency upgraded their attic to R60. The catch is visible in their solar division. One review describes a six-month delay, inaccurate electrical maps, and zero electricity shutoff warnings during a child's online school day. If you're hiring them for insulation, windows, or HVAC, you're in good hands. If solar is part of the equation, confirm timelines in writing and expect to manage the schedule yourself.
If you want an installer who'll walk you through thermal camera footage of your attic and talk you out of unnecessary work, Clear Efficiency is worth the call. But if you need solar and can't afford a six-month delay, get ironclad timelines before signing.
3 Stories That Stood Out
Nhat P. went into the project expecting a single-room insulation job but the crew inspected the whole house and uncovered that it was dramatically under-insulated. He chose the company after shopping multiple quotes — they offered the best price and even a cash/check discount — and the installers worked efficiently and courteously from start to finish. The most striking result: after the retrofit his air conditioner barely runs, whereas before it would run all day and still struggle to cool the house. Rooms that used to feel noticeably hotter now hold the same temperature as the rest of the home. Other contractors had pushed him toward replacing or re‑calibrating the entire HVAC system to fix uneven temperatures, but the simple answer turned out to be better insulation — a fix that avoided a much larger expense and should relieve stress on the AC unit that used to break every summer. He’s curious to see how winter performs, but expects similar energy savings, and appreciates that the product carries a lifetime warranty so he likely won’t need return service for this house.
Katie H. signed on after being told the job could be finished by the end of 2020 and hurried the process to meet that timeline. By December the installation had barely started, and now, almost halfway through 2021, she has panels on the roof that don’t produce power. Repeated site visits failed to yield an accurate map of her electrical system—even accounting for HOA complications—and each visit revealed a new gap in the crew’s knowledge. Technicians often showed up without notice, and frequent, short, unexplained power cuts became the norm; that proved more than an inconvenience for a household with a distance learner and a teleworker. A neighbor’s power was even cut accidentally during a hosted Zoom meeting. Communication dried up at critical moments: the crew hadn’t realized a fire inspection was required, and three weeks later Katie still hadn’t been told what to do next. What remains is a series of unfinished steps, intermittent outages, and little to no guidance from the company; her confidence that the rooftop equipment will ever function is essentially gone.
Amanda researched no less than 30 companies to replace the HVAC ducting and insulation in her attic, gathering more than a dozen in-person quotes before she settled on Clear Efficiency. She picked them because they felt the most thorough and knowledgeable, offered a fair middle-range price, and never pressured her — plus being local meant they understood the ins and outs of federal and local rebates. That local expertise ended up saving her $3,500, roughly half the project's cost. What stood out during the estimate was their process: they filmed a video while evaluating the attic and then walked her through every part of that footage so she could see exactly what they saw. Other contractors either skipped the attic, took only pictures, or didn’t share their findings, so the video walkthrough made the approach feel unusually transparent and professional. The job required several visits because SMUD needed to be involved for the seal-and-insulate rebate, but Clear Efficiency kept her informed at every step, explained the tests and tools, and respected her home by cleaning up after each visit. She has been using both heat and air since the work finished at the end of last year, no

What You Can Expect
David R chose Clear Efficiency to supply and install eighteen Maxeon Max 3 panels at his home, selecting premium panels whose extended 40-year warranty requires registration. He discovered the crew knew the latest solar technology, priced the job competitively, and completed a professional installation on schedule. Clear Efficiency handled the paperwork—submitting the NEM application and taking care of permitting—and arranged financing, which kept the whole process largely hassle-free. After the first 12 months the system generated a surplus of more than 3,000 kWh, making him eligible for Net Surplus Compensation at true-up. Confident in that performance, he bought an electric vehicle and now expects the array to cover most of his home’s electricity needs, including a central Comfort Heat Pump system and a Heat Pump Hybrid Water Heater. The detail that stands out: a first-year surplus large enough to justify adding an EV and shifting major home systems to electric.
In November 2024 Damian called Clear Efficiency in for a quote to reseal his attic and add new insulation. Don walked him through the scope of work, rebate options and estimated costs without being pushy, and when Damian asked about replacing his HVAC Don laid out clear estimates so he could decide. He ended up contracting both the attic work and an HVAC update. Jesse and his crew scheduled the jobs around his busy workday and even completed the attic while he was at the office. They stumbled over some rebate paperwork, but the company worked the issues and Damian ultimately received the full rebates and was happy with the installation quality. The detail that stayed with him: the team’s flexible scheduling that let them finish the attic while he wasn’t home.
Martin hired the company to clear and insulate an attic that had accumulated almost seventy years of debris. The crew tackled the cleanup, removing everything tucked away over decades, then completed insulation across the entire attic. He found the technicians knowledgeable, courteous, and consistently considerate through every step. The team repeatedly went beyond what he expected to deliver a thorough, professionally finished attic — clean and fully insulated.
Karen had spent two summers battling an air-conditioning system that blew no air and left her home stuck at around 85°F. She called Clear Efficiency, accepted their quote, and ended up with a full replacement of both the air conditioner and heater. The installation crew arrived polite and professional, walked her through each step, answered questions, and kept her updated as they worked. They wrapped the walls around the heater to control heat in that space, replaced and rerouted ductwork, and sealed the leaks that had plagued the old system. The team finished on schedule and exactly as quoted, cleaned up the site, and left the house functioning properly. Within two days the cooling performance amazed her — the house dropped well below what it had reached before — and after six months she noticed summer energy bills were about 8% lower. Communication stayed strong throughout the process, and the most memorable outcome for her was the combination of the rebuilt ductwork and attention to heat control that delivered both immediate comfort and measurable savings, with winter savings still to come.
John Cozen hired Clear Efficiency for an attic renovation and came away with a noticeably quieter, more comfortable home. Other contractors who visited for unrelated jobs stopped and complimented the work, saying the attic upgrade looked above and beyond the usual standard. When he had a couple of questions, the crew returned the same day, walked him through the sealing details and showed how the work improves energy usage and indoor comfort. He rated the job A+ (5/5); the thing that stuck with him was the high level of craftsmanship in the attic and the company’s prompt, clear on-site explanation of the energy benefits.
Mark had attic insulation added by Clear Efficiency and immediately noticed the difference: his home became noticeably quieter, more comfortable, and free of drafts. He experienced a smooth process from start to finish — the company’s leadership stayed in touch, crews arrived on schedule, kept the work area tidy, and completed the job efficiently. The most memorable detail for him was the tangible change in daily comfort — less noise and no more drafts — a simple upgrade with an obvious payoff.
Caity McNair hired Clear Efficiency to clean out, seal and install new insulation in her attic. She connected with Breyen, the service advisor, who patiently walked her through every step and fielded a lot of questions along the way. The crew cleaned and sealed the attic space and installed the new insulation professionally, keeping communication steady throughout the job. When SMUD offered a rebate, Clear Efficiency handled all the paperwork and submitted it for her, making the whole process feel seamless and easy. She walked away with a properly sealed, insulated attic and the rebate forms already filed — the hands-off follow-through that made the difference.
Clare M. hired Jesse and his crew to insulate the attic of her Antelope, CA home and ended up noticing a clear drop in utility bills and a much warmer interior. She and her husband Gordon were very satisfied with the workmanship and how the house held heat after the job. She singled out Jesse’s team for their thoroughness and credits them with those concrete gains in comfort and savings.
Facing ever-climbing PG&E bills, Isabel C. decided to make her home more energy-efficient by adding insulation under the floor and in the garage ceiling — the house had no underfloor insulation at all. She reached out on Yelp and Clear Efficiency contacted her; Breyen came by the next day to inspect and measure, and she had a written quote and a scheduled install date almost immediately. They insulated the floor underside and the garage ceiling because the garage heats up in summer and could be making the freezer work harder, and they also added a solar-powered attic fan in hopes of keeping the house cooler. Micheal and Jose handled the insulation work, while Yocnin and Venie installed the attic fan; all of the installers were friendly, professional, and left the work areas clean and in excellent condition. Pleased with the result, she asked Breyen about windows next; he explained that the replacement units exceeded code and cut down outside noise, so they replaced windows in the family room and master bedroom. Victor and Dennis installed the windows, which are made in California. The windows were costly, but she noticed a real difference — they keep the cool air in and have even t
