Heating Repair & Installation in Tsuen Wan

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.

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.

Common culprits: a tripped thermostat or dead batteries, a clogged filter starving airflow, a pilot/igniter fault, low refrigerant on a heat pump, or a safety lockout from a blocked flue. Change the filter and check the thermostat first; if that doesn't fix it, a technician's diagnostic is the safe next step, especially with any gas smell.

Yes — nights, weekends and holidays carry premium call-out rates, sometimes double the standard fee. If you're safe and warm enough, waiting for regular hours saves money. Treat a gas smell, carbon-monoxide alarm or no-heat in freezing weather as genuine emergencies where the premium is worth paying.

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.

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.

A service call runs roughly HKD 300-700, common repairs HKD 500-2,000, and a new gas or electric water heater supply-and-install commonly HKD 2,000-6,000. Registered gas installers charge more but are legally required for gas work.
