How does Green Air Heating and Air Conditioning 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 Green Air Heating and Air Conditioning 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.

Green Air Heating and Air Conditioning 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 Integrity6.5/10

Reviewers give Green Air a mixed-to-positive read on sales and proposal handling. Many describe clear explanations, fair deals, and transparent estimates, but a smaller set report pressure around contract changes, warranty service expectations, or getting updated pricing in writing.Solar.com's composite of published customer feedback, not a customer quote

Clear proposals and fair handling. Several reviewers say the company explained options clearly and provided estimates and invoicing that were easy to follow. These reviews also mention fair pricing for more complicated project scopes. Representative review excerpt: "Diego was transparent and helped explain the situation and our options clearly."

Transparent and professional process. Some customers report that the team was clear, timely, and professional during the estimating stage and that the work matched the proposed plan. Representative review excerpt: "Green Air was timely, clear, estimates and invoicing were clear and accurate, professional, the install and conduit routing is very well done and looks great, and the team members friendly..."

Pressure and contract follow-through concerns. A minority of reviewers describe pressure around subscriptions or contract updates and say they had trouble getting revised quotes or consistent help with warranty-related expectations. Representative review excerpt: "They kept pushing for a monthly subscription that would save some money with repairs and received Docusign emails but never received the updated quote despite reaching out to them 3-4..."

Price & financing transparency

Price Transparency5.4/10

Feedback on pricing and financing is mixed and leans cautious. Some reviewers describe cost-effective planning and clear explanations, while others report billing confusion, payment re-collection, or difficulties getting straight answers about charges and refunds.Solar.com's composite of published customer feedback, not a customer quote

Cost-conscious planning can work. A few reviewers say the project felt cost-effective when rebates and planning were part of the discussion, and that the company explained the value of the system clearly. Representative review excerpt: "For anyone interested in reducing their emissions, with rebates and planning it can be done cost-effectively, and you don't have to do the full monty to make a big difference."

Helpful explanation of value. Some customers say the team took time to explain the financial side in a way that was easy to understand and kept them informed along the way. Representative review excerpt: "They not only took the time to explain things in a way I could easily understand, but they kept me in the loop for every step of the process."

Billing and refund disputes. Other reviewers describe billing problems, duplicate payment requests, or confusion about how prior payments were applied, which pulled this category down. Representative review excerpt: "They told me they updated their billing system and needed to collect payment again."

Communication & coordination

Communication7.0/10

Communication is generally a strength for Green Air, with many reviewers praising responsiveness, updates, and hands-on coordination. The main complaints involve missed callbacks, weak follow-up, or communication gaps tied to service and billing issues.Solar.com's composite of published customer feedback, not a customer quote

Responsive and hands-on. Reviewers often say the team stayed engaged during scoping and pricing, returned messages, and communicated clearly through the project. Representative review excerpt: "By far Green Air did the best job of engaging during the project scoping and pricing phases and was really the only ones who physically came out (multiple times) to..."

Direct, useful updates. Some customers note that technicians showed what they were testing or doing, which helped them understand the work in real time. Representative review excerpt: "Arrived, identified the issue, (and my favorite) showed me what he was testing/doing."

Follow-up gaps for some customers. A smaller group reports repeated callback delays or trouble getting responses after issues came up, especially when they were trying to resolve service-related concerns. Representative review excerpt: "When called it's always "We will call you back" and after MANY calls never a call back."

Timeline reliability

Timeline Reliability6.8/10

Timeline performance is mostly positive, though not flawless. Many reviewers say permitting, PTO, and project completion moved efficiently, while a few describe delays, return visits, or projects that took longer than expected.Solar.com's composite of published customer feedback, not a customer quote

Streamlined permitting and PTO. Several reviewers say billing, permitting, and utility activation moved quickly and without much friction once the project was underway. Representative review excerpt: "Their billing, permitting and PG&E PTO process are very streamlined and my system was permitted, PTO'd and generating energy very quickly."

Timely completion for many jobs. Other customers describe the work finishing in a timely manner, even when the start was slightly delayed. Representative review excerpt: "Took care of everything in a timely manner and explained everything that he did"

Some projects ran long. A smaller set of reviewers say the project required repeated return visits or took too long because work had to be corrected before it could be completed. Representative review excerpt: "Project took way too long because they had to return several times to complete or repair work that was incorrect or not acceptable."

Workmanship & site care

Workmanship8.3/10

Workmanship is one of Green Air’s strongest areas. Reviewers frequently praise the quality of the installation, professionalism of the crews, careful cleanup, and the ability to handle more complex project conditions, with only a few complaints about faulty or incomplete work.Solar.com's composite of published customer feedback, not a customer quote

Strong installation quality. Many reviewers describe the work as properly done and efficient, and some say the results looked great or made an immediate improvement. Representative review excerpt: "So you can see, we have used them three times now and each time it has been a delight: their work was done properly, efficiently, and was reasonably priced."

Professional crews and cleanup. Customers also mention polite technicians and good site care, including cleanup and follow-up recommendations after the job was finished. Representative review excerpt: "They cleaned the solar panels and gave recommendations for some additional work."

Isolated workmanship complaints. A small number of reviewers report poor workmanship or mention repairs being needed after the initial installation. Representative review excerpt: "Poor workmanship, lots of wasted time and not in tune with the term customer service."

Long-term support & performance

Long-Term Support7.7/10

Post-install support is generally viewed positively, with many reviewers saying Green Air responded well when systems needed service or troubleshooting. There are still some complaints about warranty help, refunds, or systems needing repeated attention after installation, so this area is better than average but not complaint-free.Solar.com's composite of published customer feedback, not a customer quote

Responsive service after install. Reviewers often say the company came out quickly for service calls and explained what they were checking or fixing. Representative review excerpt: "Arrived, identified the issue, (and my favorite) showed me what he was testing/doing."

Helpful with system issues. Some customers report that Green Air diagnosed problems and restored equipment to working order when issues came up after the original project. Representative review excerpt: "To cap it off, we had an unrelated issue with our main panel and GA came out immediately, diagnosed the issue and got everything working again."

Warranty and service disputes. A minority of reviewers say they had trouble getting warranty support, refunds, or follow-through on service-related issues after installation. Representative review excerpt: "However fast forward years later, when it comes to servicing his warranties he became a nightmare to deal with."

Bottom line: Green Air Heating and Air Conditioning earns a generally favorable review profile, with especially strong marks for workmanship and solid results in communication and post-install support. The most consistent caution flags are around price transparency, billing, and some service follow-through, so the overall picture is positive but not without recurring complaints in a few areas.

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.
