Heating Repair & Installation in Andover

Annually, ideally before the cold season — a service checks safety (combustion, flue, gas), cleans components and catches small faults before they become breakdowns. Regular servicing is also commonly required to keep manufacturer warranties valid, so skipping it can cost you a claim later.

No proof of gas/HVAC registration, no diagnostic before quoting a big repair, pressure to replace immediately without explaining why, quotes with no unit model or sizing, cash-only with no invoice or safety certificate, and skipping permits. Anyone who'll work on gas without showing registration is an immediate walk-away.

A furnace blows heated air through ducts; a boiler heats water for radiators or underfloor heating; a heat pump moves heat electrically and both heats and cools. They need different specialists and have very different running costs — heat pumps are efficient but pricier to install, furnaces cheaper up front. Match the technician to your system type.

Most jobs start with a diagnostic/service-call fee, then parts and labour on top. A minor fix (thermostat, igniter, capacitor) is modest; a failed heat exchanger, blower motor or control board runs into serious money. The key decision is whether repair cost approaches replacement — past roughly half the price of a new system on an old unit, replace.

A call-out and diagnostic runs roughly £60-120, common boiler repairs £150-500, and a new combi boiler installation commonly £2,000-3,500. Heat-pump installs cost more but may qualify for a government grant.

Ask to see their Gas Safe ID card and check the licence number on the official Gas Safe Register — the card shows which gas work they're qualified for. Never let an unregistered person touch gas appliances; it's both illegal and dangerous.
