FAQs
How does a heat pump keep my Bristol home warm in winter and cool in summer?
A heat pump is essentially an all-in-one heating and cooling system. In winter it extracts low-grade heat from the outside air and concentrates it with a refrigerant cycle, then delivers that heat indoors. In summer, the process is reversed: the reversing valve changes the refrigerant flow, so the system removes heat from your home and releases it outside—just like a standard air conditioner. Because it moves heat instead of burning fuel, a heat pump can achieve efficiency ratings of 250–400 %, making it a highly economical choice for Bristol’s relatively mild climate.
What warning signs tell me I need professional heat-pump repair?
Call for service if you notice any of the following: little or no warm air even though the system is running, short cycling (turning on and off rapidly), unusual noises such as grinding or hissing, frost or ice buildup on the outdoor unit that doesn’t melt during defrost mode, water leaks around the indoor air handler, unusually high energy bills, or error codes on your thermostat. Addressing these symptoms promptly prevents further component damage and helps keep your Bristol home comfortable and safe.
How fast can you respond to an emergency no-heat situation in Bristol?
We offer 24/7 emergency dispatch throughout the Bristol area, including surrounding suburbs such as Clifton, Redland, Bedminster, and Filton. Calls received before 10 p.m. are usually attended within two hours; after-hours calls are prioritised for vulnerable customers (families with young children, elderly residents, or critical medical needs). Our vans are stocked with common heat-pump parts—contactors, capacitors, defrost sensors, fan motors—so most emergencies are resolved during the first visit.
Is it better to repair or replace my older heat pump?
The decision depends on age, current performance, and repair cost. A well-maintained heat pump typically lasts 12–15 years in the Bristol climate. If your unit is over 10 years old, needs a major component (compressor, reversing valve, or coil) that costs more than 30–40 % of the price of a new system, or has SEER/HSPF ratings below current efficiency standards, replacement is usually the smarter investment. A new A+++-rated air-source heat pump can cut electricity use by 20–40 % compared with models from the early 2010s, and generous Boiler Upgrade Scheme grants may reduce the upfront cost.
How much does a typical heat-pump repair cost in Bristol?
Minor repairs such as replacing a start capacitor or indoor blower relay often run £90–£150, including diagnostics. Mid-level repairs—defrost sensor, fan motor, or refrigerant leak test and seal—range from £180–£450. Major repairs like compressor or coil replacement can exceed £900. We always provide a written quote before work begins, and our diagnostic fee is waived when you proceed with the repair.
What maintenance can I perform to avoid future breakdowns?
1) Replace or clean the air filter every 1–3 months. 2) Keep at least 30 cm of clearance around the outdoor unit and rinse away leaves or dirt with a garden hose. 3) Make sure supply and return vents inside your home are not blocked by furniture or rugs. 4) Check that the condensate drain is clear—standing water can trip safety switches. 5) Schedule a professional tune-up each spring and autumn: we test refrigerant levels, verify defrost cycle, inspect electrical connections, and calibrate the thermostat. Customers enrolled in our Bristol ComfortCare Plan receive two maintenance visits per year, priority scheduling, and a 10 % discount on repairs.
