Opinions split sharply: many report fast, clean installation and reliable maintenance when service runs smoothly, with staff named for responsiveness. Others describe poor follow-up on enquiries, services performed without consent, and difficulty rescheduling missed visits. Staff conduct on-site (politeness, tidiness) draws consistent praise; management coordination does not.

Strong positive reviews cite quick response, good pricing, and reliable installation and repair work. Two recent one-star reviews offer no detail, making it unclear whether they reflect service failure or personal friction. The business operates across both servicing and installation, with some reviewers specifically praising prompt, professional execution on both fronts.
