Installer & Company Directory

Every listing discloses how it was verified and whether it's an affiliate relationship — see our Review Policy.

Coverage note: these listings cover large multi-state operators, chosen because their scale makes BBB status and other public records easy to check. We haven't independently verified state contractor licenses for any of them — see each listing's notes for exactly what was and wasn't confirmed. Regional and local installers will be added as they're verified.

Sunrun

Residential solar, battery storage, and EV charger installer operating in dozens of U.S. states, with both in-house install teams and a network of contracted local partners.

Solar InstallationBattery StorageEV Charger Installation

Serves: Nationwide (state availability varies by market)

BBB-accredited, A+ rated at the headquarters and most local-branch BBB profiles checked (bbb.org, July 2026); 18+ years in business per BBB filing. Not independently verified: state contractor license status. Worth reading before you sign: Connecticut's Attorney General filed a pending 2024 lawsuit alleging deceptive door-to-door sales/install practices by third-party partners Sunrun contracted with — Sunrun disputes wrongdoing and says it has cut ties with the individuals named. Get the local branch's own BBB page and ask about in-house vs. subcontracted installers before booking.

Qmerit

Nationwide network of certified, licensed electricians specializing in EV charger installation, battery storage, and panel/electrical upgrades — the certified-install partner used by several major automakers.

Serves: Nationwide

BBB-accredited, A+ rated (bbb.org, July 2026); 11 years in business per BBB filing. Not independently verified: individual installer licenses in your state — Qmerit says its network electricians are licensed and insured, but this is a marketplace connecting you to a local contractor, so confirm that specific contractor's license yourself. Some BBB reviews cite unclear quoting on load-management-device costs; ask for an itemized quote up front.

ARS / Rescue Rooter

National HVAC, plumbing, and electrical franchise (American Residential Services) offering heat pump and ductless mini-split installation alongside traditional furnace/AC work, through locally operated branches.

Heat Pump InstallationDuctless Mini-SplitsHVAC Service

Serves: Nationwide (via local branches)

This is a franchise brand — BBB accreditation, rating, and years-in-business are filed separately per local branch, not as one national score. Spot-checked branches (Memphis TN, Austin TX, Boston MA area, Aurora CO) are BBB-accredited; ratings and complaint history vary by branch, so look up the specific branch that would serve you at bbb.org before booking. Not independently verified: local HVAC contractor license for your branch.

Dr. Energy Saver

Dealer network (part of the Basement Systems group) offering home energy audits, insulation, air sealing, and crawl space/attic work through independently owned local dealers in roughly 18 states.

Home Energy AuditsInsulationAir SealingWeatherization

Serves: Multi-state network — confirm dealer coverage for your area

This is a dealer network, not a single company — each local dealer (e.g., Dr. Energy Saver of Cincinnati, of Connecticut, of NE Illinois) holds its own separate BBB accreditation and rating, and results vary by dealer. Several dealers checked are BBB-accredited; a few carry mixed reviews on pricing transparency. Not independently verified: BPI certification status or state home-improvement contractor license for any specific dealer — check the exact local dealer, not the parent brand.
