How does Advanced Improvements 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 Advanced Improvements 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.

Advanced Improvements reviews: what customers say

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

Sales & proposal integrity

Sales Integrity7.5/10

Reviewers describe the sales process as straightforward and low-pressure, with clear proposals and expectations. The evidence in this category is entirely positive, centered on honest conversations, reasonable quotes, and helpful follow-through.Solar.com's composite of published customer feedback, not a customer quote

Clear, honest conversations. Reviewers say the sales experience felt open and honest, with no sign of heavy pressure. Several describe the initial conversation and quote process as straightforward and easy to understand. Representative review excerpt: "Anthony showed up at my house on time and I will say that was one of the most honest and open conversations I had with a contractor."

Reasonable proposal framing. Customers describe quotes as reasonable and say the proposal matched what they were prepared to move forward with. One review also notes follow-up help after the contract was finished. Representative review excerpt: "He was able to write us up a quote that was reasonable and we decided to have Advanced Improvements replace our HVAC before the heat of summer."

Price & financing transparency

Price Transparency6.8/10

There is one complaint in the category, so while pricing is often described favorably, not every reviewer had a smooth experience.Solar.com's composite of published customer feedback, not a customer quote

Pricing pricing. Several also mention that the overall value felt fair for the work delivered. Representative review excerpt: "Their price was the lowest of three bids but the quality of the work and responsiveness of all involved were top notch."

Savings and financing viewed favorably. Some customers point to monthly bill savings and projected net savings as part of their positive view of the purchase. These reviews suggest the financing and longer-term cost picture were understandable to them. Representative review excerpt: "Projections for the year put me at a net Savings of roughly 30% including the cost of the financing payment."

Communication & coordination

Communication7.1/10

Most reviewers describe responsive communication and active coordination through the project. Still, a minority report problems with follow-up, service requests, or execution after installation, so the feedback is not uniformly positive.Solar.com's composite of published customer feedback, not a customer quote

Frequent updates. Reviewers say staff kept them informed with texts and calls during material delivery, inspections, and completion. Quick responses and ongoing availability after the job are also mentioned. Representative review excerpt: "Maria kept me up to date with texts and calls regarding the material delivery, inspections, and completion."

Responsive handoff and support. Some customers describe the team as quick to answer questions and courteous throughout the process. They also report that coordination across the worksite felt organized and dependable. Representative review excerpt: "He answered every text quickly, courteously, and called me throughout the process Even though my work is all done, he has still been available to answer my questions about the..."

A few service and execution complaints. A smaller group of reviewers say communication broke down when they needed service or follow-up, and one describes the company's execution as strained by taking on too many projects. These comments point to some inconsistency after the initial install. Representative review excerpt: "Overall I think this company means well but the execution seems to be very poor and they seem to take on more projects they can really handle."

Timeline reliability

Timeline Reliability7.3/10

Timeline feedback is strongly positive, with reviewers often saying the work moved on schedule and the crews arrived when expected. The category contains no complaint pattern in the evidence set.Solar.com's composite of published customer feedback, not a customer quote

On-time crews. Customers say the installers were on time and that the work stayed on schedule. Several reviews describe a smooth process from start to finish. Representative review excerpt: "The installers were always on time, and did a great job."

Fast completion on some jobs. Some reviewers point to quick turnaround, including projects completed in just a few days. Others describe the permitting and installation path as easy. Representative review excerpt: "In a matter of 3 days my old tile roof was torn off and a new asphalt shingle roof was installed."

Workmanship & site care

Workmanship7.9/10

Most reviews describe solid workmanship, professional crews, and careful handling of the jobsite. There is one complaint about installation-related concerns, but the broader pattern is positive and centers on clean, efficient work.Solar.com's composite of published customer feedback, not a customer quote

Professional installation quality. Reviewers often say the finished work looked good and was completed professionally. Some mention a mix of roofing, solar, and HVAC work being handled cleanly at the same time. Representative review excerpt: "It's been almost 18 months since Advanced Improvements installed our new roof, 9+kWh solar array, and 4T HVAC system."

Helpful on-site coordination. One reviewer notes that the crew helped run internet and cable lines while doing the HVAC and electrical work, which they viewed as a major help. This suggests attention to site needs beyond the core installation. Representative review excerpt: "Oh and they helped me run some internet and cable lines while they were running the HVAC ducts and electrical cables which was a huge help."

Isolated installation concern. A small number of comments raise concerns tied to installation durability or warranty expectations. These are not the dominant theme, but they do appear in the feedback. Representative review excerpt: "I am supposed to have a twenty year warranty on installation, it's only been over three years since they installed the panels."

Long-term support & performance

Long-Term Support7.4/10

Most reviewers say their systems continued working properly after installation and that the company remained available for later needs. There are also a few post-install complaints about production, leaks, or service follow-up, so support looks positive overall but not flawless.Solar.com's composite of published customer feedback, not a customer quote

Systems still working well later. Several customers say everything continued working properly months or years after completion, and some even returned for later projects. These reviews suggest solid longer-term performance for many installs. Representative review excerpt: "It's been almost a year since they finished their work and I haven't needed them back since everything is working properly."

Responsive repairs in some cases. Some reviewers describe the company coming back out to repair issues or handle later work, and one says they plan to use them again for future installations and repairs. That points to at least some willingness to stay involved after turnover. Representative review excerpt: "Had problems from day one, they came out twice to repair."

A few post-install complaints. A minority of reviewers report production issues, leak concerns, or difficulty getting service after installation. These comments make long-term support the most mixed part of the profile. Representative review excerpt: "One of our installed panels is clearly producing less than half the normal production starting back in late Oct 2023."

Bottom line: Advanced Improvements has an overall Solar.com Installer Score of 8.1/10, with especially strong feedback on sales clarity, timeline reliability, and workmanship. Reviews are still mostly positive in pricing, communication, and long-term support, but a smaller set of complaints appears around post-install service, coordination, and a few pricing or warranty-related issues.

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.
