FAQs
How do I know it’s time to replace my existing HVAC system rather than repair it?
Most systems in Bristol last 12–15 years if serviced regularly. Consider replacement when: (1) repair costs exceed 40 % of the price of a new unit; (2) energy bills have risen steadily despite maintenance; (3) some rooms are too hot or cold; (4) the heat pump or gas furnace still uses R-22 refrigerant, which is now banned; or (5) the unit is noisier than before and short-cycles (turns on/off frequently). A new A-rated system can cut annual heating and cooling costs by up to 30 %.
Will a new high-efficiency HVAC unit really lower my energy bills?
Yes. Modern air-source heat pumps and high-SEER/SCOP air conditioners use variable-speed compressors and smart controls that match output to demand. Replacing a 10-SEER (or older G-rated) system with a 16–18 SEER unit can reduce electrical consumption by about 35 %. In Bristol’s mild-to-cool climate, a heat pump with a seasonal COP of 4.0 can deliver four units of heat for every unit of electricity, slashing winter bills compared to electric resistance or older gas boilers.
What size HVAC system do I need for my Bristol home?
Sizing depends on floor area, insulation, window orientation, airtightness, and occupancy. As a rough guide, a typical 3-bed semi-detached house (90–100 m²) might need 7–9 kW of heating and 6 kW of cooling. During a free survey we carry out a detailed heat-loss/heat-gain calculation (under BS EN 12831) to ensure the new unit is neither undersized (runs constantly) nor oversized (short-cycles, wastes energy).
Are there local incentives or regulations I should know about?
Bristol residents can apply for the UK Boiler Upgrade Scheme (BUS), offering up to £7,500 toward an air-source heat pump. If you install a heat pump, it must be MCS-certified to qualify. Planning permission isn’t usually required for outdoor condensers provided they’re under 0.6 m³ and placed at least one metre from the property boundary, but listed buildings and conservation areas have stricter rules—our surveyor will confirm compliance.
How long does an HVAC replacement take and will I be without heating or cooling?
Most like-for-like swaps (split air-con or heat pump) take one full day; ducted or multi-zone systems can take 2–3 days. We remove and recycle the old unit, fit the new condenser/air handler, pressure-test and vacuum the refrigerant lines, and commission the controls. Your heating/cooling may be off for 4–6 hours, but we schedule work during mild weather or provide temporary heaters if needed.
What warranties and financing options are available?
All units we install come with a manufacturer’s parts warranty of 5–10 years (subject to annual service). Our workmanship is covered for 12 months under the REFCOM Competent Persons Scheme. We also offer 0 % APR financing for up to 24 months or low-interest plans up to 10 years, helping you spread the cost while you start saving on your utility bills immediately.
