Boiler, air conditioning and home systems: the maintenance nobody remembers (until it breaks)

Home system maintenance has one feature: while everything works, nobody thinks about it. Then the boiler cuts out on the first cold day, the air conditioning blows hot air in July, and you discover the last service was three years ago — or nobody knows when it was.

Regular maintenance costs less than emergency repairs, extends the life of systems and, for some, is a legal requirement.

This article gives organisational tips. Frequency and required work depend on the system, the manufacturer's and installer's instructions and, for boilers, national and regional rules: check them with a qualified engineer.

Systems to keep an eye on

• boiler: periodic servicing and efficiency checks as required; keep its logbook up to date
• air conditioners and heat pumps: filter cleaning, sanitising, pre-season check
• water heater
• water softener or purifier: salt, filters, cartridges
• electrics: test the circuit breaker (RCD) periodically
• ventilation and cooker hood: filters
• chimney and stoves, where present

1. The inventory, once

The first step is knowing what you have. In KidBox's Home section you record household items: for each system, brand, model, serial number, purchase date and warranty expiry, with the PDF manual attached. In the notes, the engineer's details: handy when you call for service.

2. Every service with the next due date

The heart of the system: on each system's record you set the next service date and how many months between services, with the reminder on. Once the engineer leaves, two minutes: update the next date and attach the report.

The engineer's report, photographed or as a PDF, is attached to the record and goes into the family documents: if you need to show it at an inspection, or to a buyer when selling the house, it's there. Put the service date in the file name, so the reports build a history.

3. DIY maintenance

Not everything needs an engineer. Cleaning air conditioner filters, topping up softener salt, testing the RCD: small jobs that get forgotten. Put them in the family calendar as recurring events — monthly or yearly — with a reminder, and decide who handles each one.

4. Book before the season

Engineers are freer out of season. Book the boiler service in late summer or early autumn, the air conditioning in spring. A reminder a month before the season starts saves you waiting in the cold, or the heat.

5. Who handles it

As with other areas of the home, an owner helps: whoever looks after the systems books engineers, keeps reports and records services. The other sees everything — deadlines, history, costs — without having to remember. More in chores between adults.

6. What upkeep costs

The cost of each service goes into family expenses, under a home category; if the engineer's invoice is due later, record it as a payment deadline in Home, which becomes an expense when paid. After a year you know what the systems really cost, and whether an old appliance needs more and more frequent repairs — useful for deciding when to replace it.

In short

An inventory of systems with manuals and details, the next service set with its interval and a reminder, reports attached, small DIY checks as recurring calendar events, engineers booked out of season, an owner for the systems and costs tracked over time. The boiler will still break one day. But much later.
