Stinson Air & Solar

4.5(176)✓ Google-verified

Stinson Air & Solar wins consistent praise for professional technicians and responsive staff who handle both solar and air conditioning work with care. Named staff like Zain, Jas, Ryan, and Max earn repeated mentions for politeness, efficiency, and willingness to solve problems on site. However, one recent complaint warns of severe installation delays stretching beyond 12 months, with vague communication after deposit payment. Most reviewers report smooth, clean, tidy installations completed promptly, yet prospective customers upgrading developer packages should clarify timelines upfront.

4.8(92)✓ Google-verifiedPublishes prices

Most customers praise Clean NRG for straightforward advice, fair pricing that undercuts competitors, and installers who solve tough roof and property logistics without fuss. Named technicians like Gary, Tam, Sadegh, and Ricky built confidence through consistency and care. Two serious complaints stand out: one customer was sold an incompatible inverter that blocked their battery plans, and the company refused accountability when cheaper solutions emerged; another was left hanging after approvals when installers backed out of a two-storey townhouse job. The business talks big on honesty but stumbled when correcting course cost money.
