• 5★ · around July 2026 · the company replied

  Janko was very professional and knowledgeable. Thank you very much for help! Highly recommend!

• 5★ · around July 2026 · the company replied

  We had a very pleasant experience with Janko back when he was with another company. He was very kind, helpful, knowledgeable, and honest. His level of communication was excellent. He would quickly answer, and always have the right answer. We could not speak for his Spanish skills, but he is fluent in Bulgarian. Though he serves the Balkan community well, every customer is a prime customer for him. We could not recommend him enough.

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

• Financing

  “& Incentives We offer multiple financing options to fit different needs: ​ Cash Loan…”

• Licensed

  “Custom system designed for your home Licensed and professional installation Help…”

Its website also mentions free estimate, but not in a sentence we can quote cleanly.

• It posts on Instagram, Facebook and LinkedIn. A page that stopped posting years ago tells you something a listing will not.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

• —The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
• —We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
• —We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
