The Verdict

Advanced Improvements is a reliable local installer, but not one we'd actively recommend. We found 29 reviews that praised their installation quality with zero defects mentioned, and 23 that singled out their post-sale support. But we also noticed a pattern of scheduling delays and unresponsive follow-up. One homeowner called repeatedly for a week before reaching a manager about a malfunctioning inverter, another waited a week for a rescheduled service appointment that the office forgot to book. The company does solid work. They use in-house crews, not subcontractors, and handle the full Net Metering process with your utility. One customer who needed a roof repair five years after installation reported that Advanced sent someone the next day, pulled panels, fixed the damage, and reinstalled everything with warranties intact. Another paid cash for a 51-panel system and saw their monthly bill drop from $300-$600 to almost zero. But that same cash customer later faced a surprise $700 charge for an inverter replacement they believed was warranty-covered. (Advanced's office manager claimed otherwise, and the owner never called back.) If you value in-house crews and expect to interact with the company minimally, they're a safe bet. If you want responsive service calls or clarity on warranty coverage, look elsewhere.

If you need solar installed competently and don't plan to call the office much afterward, Advanced Improvements will get the job done. If you expect fast service responses or transparent warranty handling, you'll want a company with tighter customer service.

3 Stories That Stood Out

1. Sam A.
Yelp | Sep 15, 2022 |

Sam A. paid $32,264 cash in 2015 for a rooftop solar system and expected the contract’s 25-year parts and labor protection to cover major failures. In August 2022 they asked the company to check the array and consider adding panels, and what followed felt more like a fight than customer service. They never received the promised welcome package, learned the original sales rep had died, and encountered a rude front-desk clerk, Maria, who refused to be helpful. Repeatedly asking for the office manager, Athena, they had to call multiple times over a week before getting through; after explaining the situation they came away convinced Athena was uninterested in resolving it. A technician finally visited for a $150 service call and discovered the Enphase inverter wasn’t communicating with the panels, so he couldn’t verify panel health and warned that Enphase inverters have a history of failures. Despite the written 25-year warranty, Athena insisted Sam would be responsible for roughly $700 to replace and install a new inverter. Sam asked for the owner to call but doubted the message would be passed along. The company scheduled the inverter replacement for next Friday — that appointment is

2. Vicktoria Weessies
Google | Dec 14, 2018 |

Vicktoria Weessies had Advanced Improvements install her home solar system about five years ago and has enjoyed substantial savings plus reliable monitoring through a phone app. During a recent rainstorm she discovered extensive roof damage that had nothing to do with the panels — just ordinary wear and tear. A company representative arrived the next day to assess the situation, and Advanced Improvements arranged to remove the panels from the affected area, repair the roof, and reinstall the array with the original warranties preserved. Five years after the initial installation, she values that the same company is still around and responded quickly to handle an urgent roof issue while keeping the system protected under warranty.

3. Joe A.
Yelp | Aug 10, 2014 |

Joe A. walked into the process skeptical—his electric bills ran $300–$600 a month and he'd heard plenty of horror stories about shady installers. He talked with Jason, who laid out every solar option plainly and without pressure, and the company offered sensible financing if needed. After shopping around, he chose Advanced Improvements because their explanations were clear and their price was the best. He ended up with 51 microinverter panels; the installer’s in-house crew (no subcontractors) finished the job in about a week, and his wife noticed how polite and helpful the crew foreman, also named Joe, was. They used top-brand components and tied the system into his home internet so he can monitor production online (Enphase Enlighten public link provided). Advanced Improvements also handled all dealings with SCE for Net Energy Metering and stayed on top of the paperwork—about a month after install NEM was active and his bill dropped to almost zero. The detail that stuck with him: a full-service team that did the install themselves and shepherded the utility paperwork so the system went live quickly and his phone shows the generation numbers in real time.

What You Can Expect

01

1. Mark C.
Yelp | May 5, 2024 |

Mark C. had Advanced Improvements install his solar array eight years earlier and returned to them when his 26-year-old tile roof finally needed replacement. In just three days the crew tore off the old tile and installed a new asphalt shingle roof, but the part that stood out was the attention to detail from Jose, their roofer. Jose not only put on a first-rate roof, he added a couple of rain diverters and even repaired the vinyl gate that the tear-off crew had accidentally broken. Maria kept him informed the whole time with texts and calls about material delivery, inspections, and project completion. He ended up with a solid new roof, a fixed gate, and steady communication — and he still remembers Jose’s extra effort.

2. James H.
Yelp | Mar 6, 2021 |

James H. chose Advanced Improvements about 18 months ago to replace his roof, install a 9+kWh solar array, and upgrade to a 4T HVAC system on his home. The job came in at a competitive price, finished professionally and on time, and when small issues popped up the crew handled them courteously and quickly. Since then the new roof has stood up to several heavy rainstorms with no problems and the ridge vent has noticeably kept the house cooler. The solar array is tracking to pay for itself within a few years, and the new HVAC heats and cools far better while using less energy than the old unit. He particularly appreciated moving the furnace and blower into the attic—what had been a cramped closet is now useful pantry space. He’d hire the team again, and the pantry conversion is the detail that still stands out.

3. Michael S.
Yelp | Feb 5, 2015 |

Michael S. brought Advanced in to install a tankless water heater at his home, and they completed the job flawlessly. When issues popped up later, he had technicians return, who diagnosed that the unit needed work and repaired it under warranty. Because of the community’s water quality, they recommended and installed a whole-house filtration system, and when calcium returned two years later they came back again and added a water softener without any fuss. During that softener install Joe went above and beyond, taking extra steps to make sure everything worked and looked right. He highlights Advanced’s professionalism and customer-focused service for sticking with the system through repairs and upgrades. He’s now considering a solar system and plans to use Advanced for that project as well.

1. Dee H.
Yelp | Jul 27, 2022 |

Dee had a rooftop solar system installed six years ago and discovered the panels and installation have held up well. They found the company’s aftercare much less dependable. Most recently a technician canceled an hour before a scheduled service visit for health reasons — which Dee accepted — but the team never followed up as promised to reschedule. A week went by, so they called back, only to get Representative Maria who didn’t recall the earlier conversation; the request effectively reset and the soonest availability pushed the appointment out another week. The core takeaway from Dee’s three-star review: solid hardware and workmanship, but be prepared to chase the company for post-installation service — the missed same-day follow-up after a cancellation was the detail that stuck.

3. Daniel C.
Yelp | Jul 20, 2018 |

Daniel C. had a new split air-conditioning unit installed a year ago and encountered problems from the start. The original installer came back twice to attempt repairs, and winter passed without needing the AC, but when he switched it on the next summer it wouldn’t run at all — and the installer had gone out of business. Another company sent a maintenance tech who managed a temporary fix that lasted only a couple of weeks. Frustrated, he called Advanced Improvements; Andrew traced the real fault, corrected it, and left the system reliably cooling the house. What lingered with him was that after two short-lived repairs, Andrew identified and fixed the underlying issue so the problem didn’t return.

1. Dustin C.
Yelp | Jun 9, 2020 |

Dustin C. shopped nearly a dozen contractors before choosing Advanced Improvements for a coordinated home overhaul that included a new roof, a revised HVAC layout, and a solar system. He picked them for their low-pressure approach and friendly crew—Anthony, Joe, Jason, Maria, and the others—who treated the job like a well-planned project rather than a hard sell. While running HVAC ducts and electrical, the team also pulled internet and cable lines for him, a small but time-saving convenience that stood out. A few months after the contract ended, they returned to relocate an HVAC register that wasn’t ventilating a bedroom properly, and handled that correction at no extra charge. It’s been almost a year since completion and he hasn’t needed any follow-up because everything is performing as expected, yet he appreciates that they’re a local company likely to be available if maintenance ever becomes necessary. The takeaway that stuck with him: responsive workmanship plus practical extras—like the wiring help and the free register fix—made the whole process feel unexpectedly thorough.

2. Jeff D.
Yelp | Jul 9, 2019 |

Jeff chose Advanced Improvements for a full roof replacement and ended up with a clean, integrated roof-and-solar system. He watched Anthony and his team coordinate with the solar contractor to remove and reinstall the panels, and the crews left a seamless finish across the whole roof. Their bid was the lowest of three, yet the workmanship and responsiveness from Anthony’s crew and the solar team felt well above what he expected for the price. The detail that stood out was how smoothly the two contractors were managed — Jeff didn’t have to juggle communications, and the end result looked like one cohesive job rather than two separate projects.

3. Liz M.
Yelp | Jun 22, 2019 |

Liz M. was shopping for someone to upgrade a solar array on her home after Enphase offered a discounted replacement, and she landed on Advanced Improvements hoping they would work on equipment another company had installed. She called and Anthony came out, inspected the eight-year-old panels, and surprised her by recommending she keep them — he judged them still the best on the market — and suggested she try simple conservation steps for 4–6 weeks before committing to adding panels. She agreed, and those small changes cut usage enough that the family now needs only half as many new panels as they originally expected. Impressed by that honesty, Liz turned to Advanced Improvements for an HVAC replacement as well. Anthony put together a reasonable quote, and Joe and a coworker arrived bright and early to remove the original furnace and AC from the 1974 house. The crew ran into a real physical challenge: the new Bryant AC was wider than the backyard gate and garage entry, so they carefully squeezed it through the front door instead — taking pains not to scuff paint or the unit — and swept up both inside and outside when they finished. Because one technician was out sick, Joe handled,
