Case study
ZenWeb designed and built the MDA Multi Enterprise website, an English site for an aircon installation, chemical wash, repair and electrical team covering the Klang Valley, Melaka, Negeri Sembilan and Johor.
MDA Multi Enterprise is an air conditioning team that installs, washes, repairs and relocates aircon units for homes and offices. It also handles electrical work such as power points, lighting and heater switches. The team works across Kuala Lumpur and Selangor, with coverage in Melaka, Negeri Sembilan and Johor, and supplies and installs units from the major brands.
Its technicians hold Department of Environment (JAS) accreditation for the refrigeration and air-conditioning sector, and the certificate is shown on the site. Chemical washes use a canvas-bag method that protects walls and floors, and new installations go through vacuum, tightness and leak tests before handover.
They want to know the full installation price before anyone visits. The Packages page lists what is included by horsepower and shows a price poster for each brand.
Many worry about water and dirt on the wall during a chemical wash. The site explains the canvas-bag method and sets out two service packages to choose from.
Commercial owners need regular servicing more than a one-off job. The Services page covers scheduled maintenance plans and electrical work in one place.

The home page leads with installation, servicing and electrical work, followed by three quick cards on installation, chemical wash and pricing. It then lists the services and the brands MDA works with, and closes with a FAQ on areas, warranty and payment.
The Packages page sets out the Basic Premium installation package by horsepower, with every inclusion listed. Below it sit the chemical wash packages, a price poster for each aircon brand and an electrical price list, each opening larger when tapped.
The Services page explains each job, from new installation and chemical overhaul to relocation and electrical works, with what each one covers. A booking form lets customers pick a service, date and one-hour slot, then sends the details through WhatsApp.
The Gallery groups site photos into installations, electrical work, behind the scenes, and vacuum, tightness and leak tests. The test photos show the gauges in use, so customers can see how an installation is checked.

Most aircon customers search when a unit stops cooling, often on a phone. On mobile, the sections stack into one column with even side spacing, and every page ends with WhatsApp and call buttons.

Aircon customers usually compare on price and worry about mess and hidden charges. Putting the full package inclusions, brand price lists and the canvas-wash method on the site answers those questions before the first call. The booking form sends a ready-made WhatsApp message, which suits a team that confirms its jobs by chat.
