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

How does Comfort King 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 Comfort King 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.

Comfort King reviews: what customers say

An independent synthesis of published customer feedback, updated September 28, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity7.3/10

Reviewers generally describe the sales process as clear, honest, and low-pressure. Several say proposals were explained carefully and pricing expectations were adjusted in ways that felt fair, though one reviewer reported concern about how a replacement was framed.Solar.com's composite of published customer feedback, not a customer quote

Clear, low-pressure guidance. Reviewers say the sales conversations were honest and professional, with guidance focused on what was actually needed rather than pushing unnecessary add-ons. Representative review excerpt: "I have nothing but the highest recommendation for this company, they are honest and professional, not trying to get you to do things or buy things that you don't need!"

Reasonable proposals. Some reviewers report that quoted costs stayed reasonable and were even reduced after design changes, which they saw as a sign of thoughtful proposal work. Representative review excerpt: "He kept the costs reasonable, and with a few design changes, even LOWERED the price he had quoted!"

One complaint about replacement framing. A minority of reviewers describe concern that a cleaning job was presented in a way that encouraged replacement instead of repair. Representative review excerpt: "The tech told me they jacked the cleaning job to persuade them to replace."

Price & financing transparency

Price Transparency6.0/10

Feedback on pricing is mixed. Several reviewers describe fair or reasonable charges, but a meaningful set of complaints focuses on warranty repair charges, service fees, and disagreement over how costs were presented.Solar.com's composite of published customer feedback, not a customer quote

Fair pricing reports. Some reviewers say the final price felt fair and that service programs made recurring maintenance cost-effective. Representative review excerpt: "The price of the service was very fair and they had a service program that was available that made the twice yearly service very cost effective."

Reasonable quote experience. A few reviewers report that quoted prices were kept in check, including cases where design changes lowered the estimate. Representative review excerpt: "He kept the costs reasonable, and with a few design changes, even LOWERED the price he had quoted!"

Concerns about charges and fees. Other reviewers describe unexpected or disputed charges, including warranty-related fees and disagreement over how repair costs were broken out. Representative review excerpt: "They charged us $220 for a warranty repair, so they absorbed no costs, plus they get reimbursed for the part from the manufacturer, so they made money, on a warranty..."

Communication & coordination

Communication7.4/10

Communication is one of the more consistently praised areas in the review set. Reviewers often mention responsive staff, clear explanations, and same-day or timely help, with only a small number reporting unanswered calls or problems getting a follow-up.Solar.com's composite of published customer feedback, not a customer quote

Responsive and helpful. Reviewers frequently say the team was responsive, friendly, and willing to explain what was happening during the job. Representative review excerpt: "In the same way, Jim was super friendly and responsive on-sight and explained what was going on in all of his work I would highly recommend this business and if..."

Same-day help. Several reviewers report quick callbacks and same-day scheduling when issues came up, which they experienced as strong coordination. Representative review excerpt: "Gabriella was great on the phone and Corey came out the same day I called, diagnosed the situation right in front of me, explained what he was doing and what..."

A few follow-up concerns. A small number of reviewers say they had trouble getting a response later when they needed service again. Representative review excerpt: "I raved a few years ago about their service and would still be raving if, when I called today, they responded to fix my unit."

Timeline reliability

Timeline Reliability7.0/10

The available review evidence points to generally reliable scheduling and project flow. Reviewers mention on-time visits, orderly installation work, and professional crews, with no complaint pattern showing up in this category set.Solar.com's composite of published customer feedback, not a customer quote

On-time scheduling. Reviewers say appointments were kept as promised and the work moved forward without obvious delays in the examples provided. Representative review excerpt: "We completely lucked out as they were very professional from the owner who first visited and gave us an estimate to the men who installed the new system to the..."

Smooth install timing. Some reviewers describe the install process as straightforward and say the crew handled the job in a professional, organized way. Representative review excerpt: "We had Comfort King install a 10kW (fairly large) solar system on our home and have been extremely happy with the experience."

Clean, orderly work pace. Reviewers also note neat electrical runs and a clean finish, which suggests the schedule and site workflow were managed well. Representative review excerpt: "Only time will tell how well the panels produce but the crew did a great job of running the electrical, clean and neat."

Workmanship & site care

Workmanship7.8/10

Workmanship is mostly praised, with reviewers highlighting careful installation, professional crews, and attention to detail. A small number of comments raise concerns about the way an issue was handled, but the dominant pattern is positive.Solar.com's composite of published customer feedback, not a customer quote

Top-notch installation quality. Reviewers describe installs as high quality from start to finish, with a professional crew and a strong overall finish. Representative review excerpt: "Jim installed a mini-split system at our home and the entire experience was top-notch from start to finish."

Attention to detail. Several reviewers say the team followed through on small fixes and made improvements after installation, which they viewed as careful workmanship. Representative review excerpt: "Despite passing all of the minimum requirements of the HERS testing, after installation Jim subsequently improved the return air flow by enlarging one of the return grills and modified some..."

One workmanship-related concern. A minority of reviewers report concern that a service visit was framed in a way that pushed replacement rather than repair. Representative review excerpt: "The tech told me they jacked the cleaning job to persuade them to replace."

Long-term support & performance

Long-Term Support6.8/10

Post-install support and system performance lean positive overall, but this area has more friction than the installation categories. Reviewers often mention reliable operation and good service, while a few raise concerns about warranty-related charges or follow-up support after the initial job.Solar.com's composite of published customer feedback, not a customer quote

Good operation after install. Some reviewers say the system kept working well over time and that the result remained satisfactory after the job was complete. Representative review excerpt: "Its been working perfect since and any time it extends our system is a bonus, at a much lower price paid."

Helpful follow-through. Others report that the team came back to diagnose or repair issues and that the work held up as expected afterward. Representative review excerpt: "Jim showed up on time as promised, quickly diagnosed and repaired the problem, and charged a fair price."

Warranty-service cost concerns. A few reviewers describe dissatisfaction with service charges tied to warranty repairs and with how later support was handled. Representative review excerpt: "They charged us $140 service charge for a warranty repair, plus another $80 processing fee for the warranty covered part."

Bottom line: Across 35 substantive Yelp reviews, Comfort King earns a 7.8/10 overall, with especially strong marks for workmanship and communication. The main softer spots are pricing transparency and post-install support, where reviewers more often mention disputed fees, warranty-related charges, or occasional follow-up friction.

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.
