What's actually included in a boiler service?
Combustion analysis, flue integrity check, gas tightness test, inspection of seals and pipework, a check of controls and thermostats, and a pressure and expansion vessel check. You get documentation on completion recording what was tested.
Do you work evenings and weekends in Johnstone & Elderslie?
Yes. Heating faults don't keep office hours, so we take emergency calls around the clock for Johnstone & Elderslie. Non-urgent work like servicing can be booked for whatever slot suits you, including evenings.
Is a service the same as a CP12?
No, and it's worth understanding the difference. A CP12 confirms gas appliances are safe to use, which is the legal requirement for landlords. A full service goes further, covering efficiency and wear items. Many landlords book both together in one visit.
My Johnstone & Elderslie property is a flat — can you still help?
Absolutely. A good share of PA5 housing is flatted, and we work in them regularly. If it's a tenement or a block with shared access, just let us know about entry arrangements when you book so the engineer isn't stuck at the close door.
How long does a service take?
Usually 45 minutes to an hour for a single boiler, assuming reasonable access and no faults found. A CP12 covering several appliances takes a bit longer.
Is it worth repairing my old boiler or should I replace it?
It depends on the age, the fault and the cost of parts. As a rough guide, once a boiler passes 12–15 years and the repair runs to a meaningful share of a new unit's price, replacing usually makes more financial sense. We'll give you both figures for your Johnstone & Elderslie property and let you decide — we don't push replacements.
Will servicing void or protect my warranty?
Protect it. Most manufacturers require documented annual servicing as a warranty condition — skip a year and a future claim can be refused even if the fault is unrelated. Keep the paperwork we give you.
Do you install new boilers in Johnstone & Elderslie?
Yes. We supply and fit A-rated combi and system boilers throughout Johnstone & Elderslie, including removing and disposing of the old unit, commissioning, balancing the system and registering the manufacturer warranty. Sizing advice is honest — we fit what your home needs, not the biggest unit we could sell.
When is the best time of year to book?
Late summer or early autumn. Everyone books in the first cold week of the year, so slots get tight exactly when you most want one. Servicing before the heating season starts also means any fault found is fixed before you depend on it.
My radiators are cold at the top — what's wrong?
That's usually trapped air, and bleeding the radiator often fixes it. If it keeps coming back, or radiators are cold at the bottom instead, that points to sludge or a balancing problem rather than air. Plenty of the terraces, semis and newer estates in Johnstone & Elderslie have systems old enough for build-up to be the culprit.
