#455 of 678 scored in California by Solar.com Installer Score

How does Cosmic Comfort compare where you live? Rankings are local; an installer that leads one city can trail in the next. See how they rank in your city →

Why this differs from star ratings: most five-star reviews say “great company” and stop, and star averages reward that. These category scores only count reviews with concrete evidence, weighted by recency and the reviewer’s track record. A company can hold a strong star average while specific categories score lower; that gap is usually where the real story is. Categories with more complaints than praise are the questions worth asking any bidder, not necessarily dealbreakers.

Where Cosmic Comfort builds

County-by-county activity from CPUC records through May 2026.

What this data covers: *Counts on this page, including the totals up top, come from investor-owned-utility interconnection records (SCE, SDG&E, PG&E). Work in municipal-utility territory, such as LADWP or city utilities, and outside California does not appear here, so this company's true totals are higher than shown. Unlike the county rankings, this profile also shows counties below the 250-install ranking floor.

Sales & proposal integrity

Sales Integrity5.7/10

Reviewers give a mixed picture of the sales process. Many describe clear, professional quotes and helpful explanations, while complaints focus on pressure, high estimates, and disagreements about what was included in the proposal or contract expectations.Solar.com's composite of published customer feedback, not a customer quote

Clear quotes and explanations. Several reviewers say the quoting process was straightforward and professional, with good explanations of the work and expectations. Representative review excerpt: "Adam did an excellent job at my house giving me an accurate and professional quote at an agreeable price."

Pressure and high estimates. Complaint patterns include customers describing pushy follow-up, large quoted prices, and feeling steered toward the biggest sale rather than their stated needs. Representative review excerpt: "After we decided not to move forward with their estimate, they repeatedly argued with us over the phone and pressured us to use their company."

Proposal mismatch concerns. Some reviewers also report that discounts or sales pitches did not resolve concerns about pricing, and that the final proposal felt much higher than other estimates. Representative review excerpt: "Even with "

Price & financing transparency

Price Transparency4.7/10

Feedback on pricing is mixed but leans negative. Some reviewers say the price felt reasonable for the work performed, but others describe surprise at costs, strong upselling, and frustration when price discussions did not lead to a clearer or more flexible outcome.Solar.com's composite of published customer feedback, not a customer quote

Reasonable to some customers. A portion of reviewers say the pricing felt fair or reasonable for the service received. Representative review excerpt: "Let's face it, electrical work is not cheap, but I felt it was a reasonable price especially considering my wife would stop reminding me that we needed to get it..."

Higher-than-expected pricing. Complaint reviews frequently mention quotes that felt too high, including comments about discounts not changing the overall price concern. Representative review excerpt: "Even with "

Upsell and refund frustration. Some customers describe being pushed toward additional services or feeling they did not get the refund response they expected after price concerns arose. Representative review excerpt: "When he saw me balking at the price, he said well, we also do heating and cooling so if you want to sign up for $299 a year, we can..."

Communication & coordination

Communication7.5/10

Communication and coordination are generally viewed positively, with many reviewers praising responsiveness, clear updates, and organized handoffs. The main complaints involve missed calls, appointment issues, and occasional frustration when scheduling or follow-up broke down.Solar.com's composite of published customer feedback, not a customer quote

Responsive updates. Many reviewers say the team communicated promptly and kept them informed during the job. Representative review excerpt: "Big shout out to the electricians for their excellent work and Jessica for communicating with me in a no nonsense fashion and so promptly."

Professional on-site coordination. Customers also describe crews who handled moving items, cleaned up, and coordinated the work smoothly once on site. Representative review excerpt: "The team who came to my home moved all the furniture or items required on their own and put everything back as it was found."

Scheduling and follow-up gaps. Some complaints focus on missed arrival calls, canceled appointments, or difficulty getting a return call when the schedule changed. Representative review excerpt: "I had a time slot booked, but they canceled my appointment because they couldn't look up the ZIP code for the address I had already provided."

Timeline reliability

Timeline Reliability7.5/10

Timeline feedback is mostly positive, with several reviewers saying projects finished on time or even ahead of schedule. A smaller set of complaints points to no-shows, cancellations, or delays tied to parts availability and scheduling issues.Solar.com's composite of published customer feedback, not a customer quote

Projects finished on schedule. Reviewers often say the work was completed on time or ahead of the estimated finish date. Representative review excerpt: "They finished the project well before the estimated completion time, and gave my wife and I a detailed explanation on how to utilize the installed devices."

Fast, efficient completion. Some customers describe installations that wrapped up quickly and moved through inspection steps without major delay. Representative review excerpt: "He spent a few hours completing the work and I scheduled a final inspection for my main and sub panels with the building department for the very next day."

No-shows and delays. The complaint pattern includes missed appointments, canceled visits, and cases where parts delays stretched the timeline. Representative review excerpt: "Made and appointment for a consultation and the guy never showed up."

Workmanship & site care

Workmanship8.4/10

Workmanship is one of the stronger areas in the review set. Most reviewers describe professional crews, solid installation quality, and careful cleanup, while a smaller number report issues such as incomplete cleanup or damage-related concerns.Solar.com's composite of published customer feedback, not a customer quote

Professional, knowledgeable crews. Many reviewers say the installers were hardworking, knowledgeable, and attentive to the job. Representative review excerpt: "I just want to say that the young men that came out to do the job were hardworking , were very knowledgeable about what they were doing and did an..."

Good workmanship and cleanup. Customers also report prompt service, strong workmanship, and crews that handled the work carefully on site. Representative review excerpt: "But they really broke it down for me the prompt service and workmanship was above and beyond."

Cleanup or damage concerns. A smaller complaint pattern mentions follow-up needed after installation, including incomplete cleanup or concerns about damage during the job. Representative review excerpt: "He apologized for the condenser not being cleaned and would talk to the tech, offered to come back to clean the condenser, but offered no refund or partial refund, so..."

Long-term support & performance

Long-Term Support7.0/10

Post-install feedback is mostly positive, with many reviewers saying the company helped get systems working better and responded quickly when issues came up. The complaints center on unresolved service problems, missing history in the portal, and repair situations that were not fully settled right away.Solar.com's composite of published customer feedback, not a customer quote

Prompt help after install. Reviewers frequently say the company responded quickly when systems needed attention after the initial job was done. Representative review excerpt: "One of the best companies out there, AC went out last night, they got here the next day and fixed it right away!"

Issues resolved and explained. Some customers describe technicians figuring out the problem, explaining options, and restoring the system to working order. Representative review excerpt: "Thanks to Angel from Cosmic for figuring out what's wrong, educating me on options for solutions, and getting my house back to working order."

Ongoing service gaps. Complaint reviews mention longer-running service issues, limited portal history, or situations where the problem was still not fully resolved. Representative review excerpt: "It's now been 4, very warm, weeks since the beginning of the non working issues with the parts not available from the manufacturer, recent attempts to locate the parts from..."

Bottom line: COSMIC COMFORT’s review profile is strongest on workmanship and generally positive on communication and timeline reliability, while sales integrity and price transparency are more mixed. Post-install support trends positive overall, but reviewers do describe some service and follow-up gaps after the job is complete.

Important context: this chart shows investor-owned-utility records only. Companies that shift work toward municipal-utility territory (LADWP and city power departments) or other states will show declining bars here even while building steadily elsewhere, and 2025-26 records also lag real installation dates. Treat this as a partial window, not the company's full trajectory.

How we built this data

Methodology: Counts are residential PV interconnections in investor-owned-utility territory (PG&E, SCE, SDG&E) per CPUC Rule 21 public records through May 2026. Postal and name variants are merged. Municipal utility territory such as LADWP, Glendale, Pasadena, Burbank, Anaheim, and Riverside Public Utilities is not included in those CPUC counts. Counts show recorded installations, not quality ratings. Reported costs are self-reported on owned-system interconnections. No installer can pay for placement.

Who we are: Solar.com is a solar marketplace — we connect homeowners with installers and earn a fee when projects move forward. These rankings and scores are computed from public installation records and published customer reviews. No installer can pay for placement, and no installer — including those we work with — can pay to change a score.
