How does Marthedal Solar, Air & Heating 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.

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.

Marthedal Solar, Air & Heating reviews: what customers say

An independent synthesis of published customer feedback, updated September 23, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity6.8/10

Reviewers describe the sales and proposal experience as straightforward and trustworthy overall. The available comments emphasize clear recommendations, limited pressure, and expectations that matched the work delivered.Solar.com's composite of published customer feedback, not a customer quote

Clear, low-pressure sales. Reviewers say the sales process felt honest and not pushy, with recommendations they felt comfortable trusting. Representative review excerpt: "We have never felt pressured, we have never received bad information and their work has always been of high quality."

Helpful guidance. Customers describe sales and design support as thoughtful and useful through the installation process. Representative review excerpt: "I want to thank Chris Hernandez for his helpfulness and thoughtfulness in the sales, design, and installation of our air system."

Trust in recommendations. Reviewers report confidence in the diagnosis and suggested work, with no complaint pattern surfaced in the reviewed evidence. Representative review excerpt: "They are honest and you can believe their diagnosis and recommendations and you can trust their workers to do the right thing when no one is around."

Price & financing transparency

There was not enough review evidence in this corpus to form a meaningful category read on pricing or financing transparency. The analyzed reviews did not provide substantive comments about final price, financing terms, deposits, refunds, surprise costs, or incentive timing.Solar.com's composite of published customer feedback, not a customer quote

No usable evidence. This category had no evidence reviews in the analyzed corpus, so the review set does not support a specific pattern here.

No pricing pattern. Because the corpus contains no substantive pricing or financing comments, no positive or negative conclusion is warranted.

Communication & coordination

Communication7.0/10

Reviewers describe communication as prompt and coordinated, with several comments about quick responses and thorough follow-up. The evidence emphasizes responsiveness, clear explanations, and respectful in-home interactions.Solar.com's composite of published customer feedback, not a customer quote

Prompt follow-up. Reviewers say calls were returned quickly and questions were explained thoroughly. Representative review excerpt: "He follows up promptly on all calls and explains thoroughly any questions that you may have."

Fast problem response. Customers report that the team came out quickly, including after-hours help when needed. Representative review excerpt: "I called, and even after hours, they had someone out to me (a service manager) who corrected it, replaced a capacitor and all was well WITHIN AN HOUR!"

Respectful in-home coordination. Reviewers describe the personnel as considerate of the household and careful not to get in the way. Representative review excerpt: "The personnel that worked in our house were so respectful of our family and were so concerned about not getting in our way."

Timeline reliability

Timeline Reliability6.8/10

Reviewers generally describe scheduling and project timing as dependable. The available comments point to work being completed as promised, with the process moving from first contact through final inspection without notable timing issues in the reviewed set.Solar.com's composite of published customer feedback, not a customer quote

Timing matched expectations. Reviewers say the installation timing went as they were told and the work was neat. Representative review excerpt: "The timing and the neatness of the installation of my air conditioner went just as I was told."

Strong overall installation experience. The reviewed comments reflect a consistent view that the installation process and final result were handled neatly and professionally. Representative review excerpt: "From the first contact to the final inspection everyone was very helpful, friendly and professional."

Long-term support & performance

Long-Term Support5.0/10

This category reads more mixed than the others because the evidence set is smaller and centered on service after installation. Reviewers do describe quick issue resolution and helpful ongoing service, but the weaker score suggests the post-install picture is less complete and less consistently documented than the installation feedback.Solar.com's composite of published customer feedback, not a customer quote

Quick service response. Reviewers report prompt help when problems came up, including rapid on-site correction.

Service-plan value. Customers say a service plan can be helpful and describe the team as knowledgeable and pleasant to work with. Representative review excerpt: "I strongly recommend a service plan with Marthedal, it will help in so many way."

Limited post-install evidence. The available reviews mention support and performance positively, but the smaller evidence set leaves the long-term service picture less fully developed. Representative review excerpt: "These are honest, knowledgeable, and pleasant people to work with, and I suggest anyone looking for repairs, parts, or regular service go with them."

Bottom line: Across the reviewed Google feedback, MARTHEDAL SOLAR, AIR & HEATING is described positively for sales clarity, communication, scheduling, and installation quality. The weakest read is long-term support & performance, where the available evidence is limited and more mixed in completeness rather than strongly negative. Pricing and financing transparency could not be assessed from the reviewed corpus.

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.
