The Importance of Regular AC Maintenance
Protect Your Investment
Air conditioning systems are an investment, and as a home or business owner the last thing you want to be doing is worrying about maintenance or experiencing a complete breakdown. Our maintenance program is for regular servicing of both domestic and commercial air conditioning units.
The first step is to carry out a comprehensive assessment and service of your air conditioning systems. Following this, we can design a customised contract specifically for you. Contracts go for 12 month, and automatically roll over unless we are advised otherwise in advance.
You will receive a reminder prior to each scheduled maintenance visit, and your system details will be logged on our database, so we have a record of any issues or repairs which have been carried out.
