They installed new AC and furnace for me last december, First the freon was leaking and now SDGE saying there is gas leak. Called the company several times, no one answer, no return call either.

This company does not pay its bills. We were contracted to perform work by the owner Carlos of 5 Diamond for a building in Chula Vista. They have been paid in full for the work that we performed and still have not paid us. It is $6,000 and has been almost a year. They do not answer their phone or emails.

Carlos and his company used our services, was paid for our services from the general contractor and kept the money paid to him for us. He has since ghosted us and will not return phone calls. We did receive an email response after numerous attempts telling us to contact his bankruptcy lawyer, but the number is not valid. I would be careful doing business with this company.
