How does Mauzy Heating Air Solar Energy 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 Mauzy Heating Air Solar Energy 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.

Mauzy Heating Air Solar Energy 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 Integrity7.2/10

Reviewers often describe the sales and proposal process as honest, thorough, and able to account for the actual scope of work. At the same time, a meaningful minority report pressure, incomplete estimates, or pricing that felt high or hard to justify.Solar.com's composite of published customer feedback, not a customer quote

Clear, detailed proposals. Many reviewers say staff explained options, risks, and repair paths in a straightforward way that helped them understand what was needed. Representative review excerpt: "He laid out multiple paths forward, explained the benefits and risks of each, and was completely honest and straightforward throughout."

Pressure or quote concerns. Some reviewers describe pushy sales behavior or estimates that felt incomplete or too aggressive for the work involved. Representative review excerpt: "Rating is for Mauzy who, while good, is a bit high on Price (not horrible, just a bit) and very pushy."

Thoroughness sometimes uncovered added needs. A few reviewers say the company’s process identified issues that a cheaper quote missed, which changed the final recommendation. Representative review excerpt: "I had another quote that was cheaper, but that company didn't even go into my attic, so they didn't realize I needed new duct work."

Price & financing transparency

Price Transparency3.3/10

This category draws the most criticism. Reviewers frequently describe prices as high, quotes as unclear, and charges as difficult to reconcile with the work performed, though some customers do report transparent cost discussions and workable solutions.Solar.com's composite of published customer feedback, not a customer quote

Pricing often felt too high. Many reviewers say charges, parts, or service calls seemed expensive relative to the work done, with some describing estimates as far above expectations. Representative review excerpt: "I was quoted almost $800 for a part that would cost under $100 and for labor that would take a new tech under 30 minutes and an experienced tech under..."

Cost discussions could still be useful. Some reviewers note that estimates identified potential problems along with associated costs, even when the final price was not viewed as favorable. Representative review excerpt: "Good job on system check pointed out potential problems along with costs."

Some customers saw clear cost options. A smaller group says costs were explained directly and that multiple quote levels or pricing discussions made the decision easier. Representative review excerpt: "He was very transparent throughout the entire scope of the project and delivered multiple reasonable quotes of varying levels of work."

Communication & coordination

Communication7.0/10

Feedback on communication is generally positive, with many reviewers praising responsive staff, clear updates, and smooth coordination. Still, reviewers also describe missed callbacks, booking confusion, and weak follow-up after the initial visit or install.Solar.com's composite of published customer feedback, not a customer quote

Helpful updates and follow-through. Many reviewers say they were kept informed about scheduling, parts, and return visits, which reduced stress during the job. Representative review excerpt: "I was kept in the loop about ordering the necessary parts and his return time."

Missed callbacks and weak follow-up. Some reviewers report that calls, emails, or post-install questions were not answered promptly, especially when they needed additional help. Representative review excerpt: "But as after the installation was completed, i haven't gotten my emails, text or phone calls answered about some follow ups i had to made, like the post-installation inspection."

Some coordination was detailed but not complete. A few reviewers describe clear reports or inspection feedback, while also noting gaps in the handoff or follow-up process. Representative review excerpt: "He finished his inspection quickly and provided a detail Ed report on potential repairs that needed to be made as well as price estimates."

Timeline reliability

Timeline Reliability5.8/10

Timing feedback is mixed. Many reviewers describe fast scheduling, prompt completion, and projects that moved quickly once approved, but others report reschedules, appointment confusion, and no-shows that disrupted their plans.Solar.com's composite of published customer feedback, not a customer quote

Fast completion when things stayed on track. Some reviewers say the job moved quickly from scheduling to installation and that the work was completed within the expected window. Representative review excerpt: "The whole process from starting with the call the schedule the diagnostic call to getting the replacement was super fast and simple."

Reschedules and no-shows. Other reviewers describe delays, cancelled appointments, or being left waiting without notice, especially when service windows changed at the last minute. Representative review excerpt: "They delayed my appointment to July, then cancelled the day before to push it to August, and then completely no-showed without any notice on the day of the appointment."

Occasional scheduling friction resolved. A few reviewers mention a scheduling snafu that was eventually worked out, suggesting some timing issues were recoverable rather than persistent. Representative review excerpt: "Even with a scheduling snafu they worked it out."

Workmanship & site care

Workmanship8.4/10

This is the strongest category in the review set. Reviewers frequently praise professional crews, careful installation, clean work areas, and technicians who explain what they are doing, though a small number mention incomplete or sloppy finish work.Solar.com's composite of published customer feedback, not a customer quote

Professional, careful crews. Many reviewers describe technicians as knowledgeable, hardworking, and respectful of the home while completing the job. Representative review excerpt: "It is so nice to have functioning AC again, and these three gentlemen were professional, hardworking, friendly, helpful and had great senses of humor!"

Cleanup and finish quality are often praised. Reviewers commonly mention that the work area was left clean and that the job was completed in a professional manner. Representative review excerpt: "He completed the work quickly, professionally, and left the area clean when he was finished."

A few finish details drew criticism. Some reviews mention issues like loose parts, wiring cleanliness, or incomplete reassembly after service. Representative review excerpt: "I found the cover not completely seated/installed back on the outdoor condenser unit and a screw laying on the concrete."

Long-term support & performance

Long-Term Support5.0/10

Post-install support is mixed to negative overall. Some reviewers report helpful warranty service and effective maintenance, but others describe systems that continued to have problems after the job or experienced slow follow-up when repair help was needed.Solar.com's composite of published customer feedback, not a customer quote

Warranty support can be helpful. Several reviewers say diagnostics or follow-up work was handled under warranty and that technicians advocated for coverage when needed. Representative review excerpt: "David was very professional and was willing to advocate for us if needed as far as getting maintenance work covered under warranty."

Performance problems after installation. Other reviewers report systems not running correctly after service, including early failures or issues that required more repair work. Representative review excerpt: "I’ve had my system for two weeks, I went to use it today and it only blew warm air."

Follow-up sometimes took extra outreach. A few reviewers say they had to make repeated calls or emails before someone responded about post-install concerns. Representative review excerpt: "After making a few more calls and emails trying to reach someone, I was contacted by a manager who assured me they would be out to look at the system..."

Bottom line: MAUZY HEATING AIR SOLAR ENERGY reviews point to strong workmanship and generally solid day-of-service professionalism, but pricing transparency and post-install support are the biggest sources of concern. Communication and scheduling are more mixed, with many customers reporting good coordination while others describe delays, missed callbacks, or appointment problems.

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.
