FAQs

Q: Which of these can I do myself?
A: The list groups simple checks apart from jobs marked for a qualified technician. Your unit's manual and your technician decide what is safe for you to do.
Q: Does it cover every type of cooling system?
A: No. Everyone starts with the same list. Window units, central systems and heat pumps differ, so remove the items that do not apply and add your own.
Q: Are my ticks saved?
A: Yes, in your browser on this device. They are not sent anywhere and do not follow you to another device or browser.
