FAQs
What does a full HVAC overhaul include?
A complete HVAC overhaul involves a comprehensive assessment of your existing heating and cooling systems, followed by replacement or major refurbishment of worn components. Typical elements include removing outdated furnaces, boilers, air-handling units, condensers, or ductwork; installing energy-efficient replacements sized for your property; upgrading thermostats and control wiring; sealing or re-insulating ducts; and rebalancing airflow throughout the building. Electrical work, condensate drainage, and refrigerant line upgrades are also addressed to ensure the new equipment operates safely and at peak efficiency.
How long does an HVAC overhaul take for a typical Bristol home?
For an average three-bed semi-detached or terrace house in Bristol, most overhauls are completed within 3–5 working days. Day 1 is usually dedicated to system isolation, safe removal, and disposal of old equipment. Days 2–4 focus on installing the new furnace or heat pump, indoor air-handler, outdoor condenser, and any required duct or pipe modifications. The final day covers commissioning, pressure/leak testing, setting up smart controls, and homeowner orientation. Larger properties, complex duct rerouting, or unexpected findings such as asbestos lagging can extend the timeline, but we keep you informed with daily progress updates.
Are there energy-efficiency incentives or grants available in Bristol for HVAC upgrades?
Yes. Homeowners in Bristol can benefit from several UK-wide incentives, such as the Boiler Upgrade Scheme (BUS), which offers grants of up to £7,500 for qualifying air-source or ground-source heat pumps. The ECO4 (Energy Company Obligation) programme may also provide funding for low-income or vulnerable households to improve insulation and heating efficiency. Additionally, 0% VAT currently applies to heat pumps and certain solar-assisted heating technologies until March 2027. We guide you through eligibility checks, paperwork, and liaising with Ofgem-approved bodies so you can maximise available savings.
How much can I expect to save on energy bills after an overhaul?
Savings vary based on your previous system’s age and efficiency, property insulation, and chosen replacement equipment. Customers moving from a 60%-efficient non-condensing boiler to a modern 94%-efficient condensing boiler typically see 20–25% reductions in annual gas use. Switching from electric resistance heating to an A+++ rated air-source heat pump can yield 40–50% lower running costs, especially when paired with smart thermostats and time-of-use tariffs. We provide a personalised energy-use forecast during our proposal stage, using industry-standard SAP calculations and local Bristol utility rates.
Do I need planning permission to install new air-conditioning units in Bristol?
Most domestic external condensers fall under Permitted Development (PD) rights in England, so planning permission is not normally required provided the unit meets noise limits (no more than 42 dB(A) at 1 m from a neighbour’s window) and is installed at least 1 m away from the property boundary. Listed buildings, flats, or homes in conservation areas—including parts of Clifton and Redland—often require formal consent. Commercial premises also have different thresholds. Our team conducts a site survey, checks Bristol City Council’s planning portal, and offers a full planning application service if needed.
How often should my overhauled HVAC system be serviced?
We recommend a professional service once every 12 months for boilers, heat pumps, and air-conditioning systems to maintain manufacturer warranties and keep efficiency levels high. The visit includes cleaning heat exchangers, replacing filters, checking refrigerant charge, testing safety controls, and verifying airflow rates. For high-usage commercial systems, a biannual service schedule is advisable. Between visits, homeowners should inspect and replace filters quarterly, keep outdoor units free from leaves and debris, and monitor energy consumption for unexpected spikes that could indicate emerging issues.
