How does Home Upgrade Specialist 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 Home Upgrade Specialist 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.

Home Upgrade Specialist reviews: what customers say

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

Sales & proposal integrity

Sales Integrity7.4/10

Reviewers most often describe the sales process as straightforward, with several saying estimates felt reasonable and proposals matched what was delivered. Complaints focus on repeated outreach after quote requests, along with a smaller set of comments about pricing or added charges feeling higher than expected.Solar.com's composite of published customer feedback, not a customer quote

Clear, low-pressure proposals. Many reviewers say the initial sales conversation was helpful and not pushy, with estimates and recommended work generally described as fair and easy to understand. Representative review excerpt: "Fixed the problem and suggested some upgrades (no high pressure sales!)."

Pricing expectations sometimes questioned. Some reviewers report concerns about quoted or add-on pricing, including charges that felt higher than expected and occasional disagreement over what was included. Representative review excerpt: "Greg is a very nice guy and told me he adjusted a Ptrap on PVC draining the unit , refilled 1lb of Freon for $200 ( very high !) when..."

Persistent outreach complaints. A subset of reviewers say they continued to receive follow-up calls after asking for a quote or after making an initial inquiry, which they found intrusive. Representative review excerpt: "I put in a Yelp request for HVAC repair quotes about a month ago and this company has not stopped bothering me since."

Price & financing transparency

Price Transparency6.7/10

Some comments mention incentive timing or rebate timing issues, while others describe invoice or quote-related frustrations.Solar.com's composite of published customer feedback, not a customer quote

Pricing pricing praised. Positive reviews often say the company offered good value, with several customers describing the pricing as reasonable or among the better quotes they received. Representative review excerpt: "They did a super great job, efficient, pleasant to work with, timely manner and a great competitive price."

Billing and payment confusion. Some reviewers report problems with invoices, payments, or unexpected charges, including cases where paperwork details or payment requests created confusion. Representative review excerpt: "They also had the wrong business address on their invoice resulting in my payment being sent to the wrong place and being threatened to have my payment sent to a..."

Quote-related fee concerns. A few customers say they were surprised by charges tied to estimates or pre-work visits, and some also mentioned having to ask repeatedly for answers about rebates or similar timing issues. Representative review excerpt: "He opened the system from the roof, evaluated it and then asked my wife for an $89 payment for the quote."

Communication & coordination

Communication7.2/10

Reviewers commonly praise the team for being responsive, professional, and easy to reach during active projects. At the same time, there are notable complaints about missed callbacks, booking confusion, and instances where customers say they were not kept informed about scheduling or follow-up.Solar.com's composite of published customer feedback, not a customer quote

Responsive project communication. Many reviewers say communication was clear from start to finish, and some note that multiple people on the team were easy to reach and helpful. Representative review excerpt: "From start to finish, the estimator, project manager, installers, and even the company president were all professional, responsive, and easy to reach."

Clear explanations and coordination. Customers also report that the company explained the work well and handled coordination across the project in a professional way. Representative review excerpt: "He was very patient and made it easy to understand what and how it needed to be fixed."

Missed follow-up and reachability complaints. Other reviewers describe difficulty getting callbacks or updates, and some say appointments were booked without the right service coverage or follow-through. Representative review excerpt: "They do not show up on time, sometimes skip appointments altogether with no communication."

Timeline reliability

Timeline Reliability6.7/10

Reviews are split between customers who say projects finished on schedule and those who report missed appointment windows or slow follow-up. Permit and inspection handling is sometimes described as smooth, but there are also complaints about no-shows and schedule changes.Solar.com's composite of published customer feedback, not a customer quote

On-schedule completions. Several reviewers say the work was completed on time and that the company kept the process moving through permits and inspections. Representative review excerpt: "The project was completed on time and within budget, with great attention to detail."

Permit coordination can go smoothly. Some customers specifically mention that permitting and inspections were handled without trouble and that they were kept updated along the way. Representative review excerpt: "They took care of all the Burbank permitting, kept us updated, and delivered on schedule."

No-shows and missed windows. A number of reviewers report missed appointment times, skipped visits, or shifting arrival estimates that created delays and frustration. Representative review excerpt: "They were supposed to send their licensed technician Jose Wednesday from 2-4PM but he never showed up, so he texted and said he should be there before 6:30PM."

Workmanship & site care

Workmanship8.6/10

This is one of the stronger areas in the review corpus. Most reviewers describe the crews as professional, efficient, and careful with cleanup, though a small number of comments mention damage, drainage issues, or work that later needed correction.Solar.com's composite of published customer feedback, not a customer quote

Professional installation quality. Many reviewers say the installation was handled efficiently and with strong attention to detail, and that the finished work met expectations. Representative review excerpt: "The installation was completed professionally, efficiently, and with great attention to detail."

Cleanup and site care praised. Customers also note that crews cleaned up after themselves and made sure the equipment was working before they left. Representative review excerpt: "He removed the old unit, installed the new one, cleaned up the area, and made sure everything was working before he left."

A few site damage complaints. A smaller set of reviewers report issues such as leaks, drainage problems, or cleanup concerns that they say required extra follow-up. Representative review excerpt: "This required a home insurance claim to get the water damaged fixed and they temporarily moved the drainage to just drain directly onto the roof."

Long-term support & performance

Long-Term Support6.3/10

Post-install support is the weakest-rated area in the set, even though some customers say the system performed as promised and issues were eventually addressed. Complaints center on warranty handling, repeated service calls, limited responsiveness, and confusion around rebate timing or follow-up support.Solar.com's composite of published customer feedback, not a customer quote

Some systems perform as expected. Positive reviews say the installed systems have continued to operate properly and that issues were identified and addressed when service was needed. Representative review excerpt: "The workmanship was top-notch, and the system is performing exactly as promised."

Warranty support frustrations. Other reviewers say they had trouble getting help after installation, including questions about what was covered and repeated calls to get answers. Representative review excerpt: "Charge for items that should be covered by their own warranty."

Rebate timing and follow-up delays. Some customers mention waiting for rebate-related updates or post-install follow-through and say they had to contact the company multiple times for information. Representative review excerpt: "we are expecting a rebate (which is the only reason we hired this company vs our normal AC guys) and have had to call 5+ times trying to get answers."

Bottom line: Home Upgrade Specialist’s reviews lean positive overall, with especially strong marks for workmanship and generally solid sales, communication, and pricing feedback. The main watch-outs are timeline consistency and post-install support, where reviewers more often describe delays, missed follow-up, and warranty or rebate timing frustrations.

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.
