Reviews
What customers say
Customers describe technicians as polite or courteous. One customer valued a detailed explanation, while another said Mr. Summers showed the problem and had the parts, which he replaced. Experiences were mixed: one customer said the heating issue was not fixed and the system stopped working again, requiring another appointment; another was unhappy about a charge for work, saying they expected to review the issue and invoice before work began.
