Experienced Team | Ventilation and Air Quality | Heating and Air Conditioning | Bristol
From cosy Clifton terraces to bustling business units in Bedminster, HEP’s seasoned engineers have spent decades fine-tuning the breath of Bristol’s buildings. We listen, measure and model before we ever lift a tool, crafting bespoke systems that balance temperature, humidity and airflow with whisper-quiet efficiency. Our specialists are qualified to the latest BESA and NICEIC standards, so you can trust every duct, filter and sensor we install to work flawlessly from day one.
Whether you’re battling condensation in a Victorian loft conversion or need clean-room standards for a new fabrication lab, we make “impossible” briefs feel effortless. The result is healthier teams, lower energy bills and the peace of mind that comes from expert after-care—because great heating and cooling only matter when your ventilation and air quality are just as exceptional. Ready to breathe easier? Call HEP and feel the difference.
FAQs
What types of heating, cooling and ventilation systems do you install and maintain in Bristol?
Our team is qualified to design, install and service a full range of domestic and commercial HVAC equipment, including gas and combi boilers, air-source and ground-source heat pumps, high-efficiency furnaces, split and multi-split air-conditioning, VRF/VRV systems, ducted and ductless units, mechanical ventilation with heat recovery (MVHR), positive-input ventilation (PIV) and whole-house air-purification systems. All equipment is supplied from leading manufacturers, comes with full warranties and is commissioned to meet (or exceed) current UK Building Regulations and Bristol City Council planning guidance.
How often should I have my boiler, air-conditioner or ventilation system serviced?
For most properties we recommend a full professional service once a year for boilers, furnaces, MVHR and PIV units, and at least once a year—ideally every six months—for air-conditioning systems that run in both heating and cooling modes. Regular maintenance keeps manufacturer warranties valid, ensures compliance with F-Gas leak-testing rules, improves energy efficiency by up to 15 %, and helps detect minor faults before they become expensive breakdowns. Filter changes, safety checks, flue-gas analysis and controls calibration are all included in our standard service visit.
What are the typical signs of poor indoor air quality and how can you help?
Common indicators include persistent condensation on windows, musty odours, visible mould, aggravated asthma or allergy symptoms, tiredness or headaches, and a general feeling of stale air. We carry out detailed IAQ assessments using calibrated CO₂, VOC and particulate sensors, then recommend practical solutions such as upgrading to high-MERV or HEPA filters, installing UV-C sterilisation, adding mechanical extract fans in moisture-prone areas, or fitting a balanced MVHR system that recovers up to 90 % of heat while supplying fresh, filtered air. Our goal is to create healthier, more comfortable living and working environments throughout Bristol.
Can you improve ventilation in older Bristol properties without spoiling their character?
Yes. Many Georgian, Victorian and early-20th-century buildings in Bristol have limited space for ductwork and strict conservation requirements. We offer discreet solutions such as low-profile MVHR units with slimline ducts routed through loft voids or behind cornices, single-room heat-recovery ventilators where full ducting is impossible, and heritage-style trickle vents matched to existing woodwork. All work is planned in consultation with homeowners, listed-building officers where applicable, and carried out with minimal disturbance to original features.
How can I make my heating and cooling system more energy-efficient and reduce utility bills?
Start with a professional efficiency audit. We look at insulation levels, system sizing, control strategies and actual run times. Upgrades might include smart thermostats with weather compensation, zoned control valves, variable-speed inverter drives, balancing radiators or air flows, and replacing older R-410A units with high-SEER R-32 models or heat pumps. Regular cleaning of coils and filters alone can cut energy use by 5–10 %, and switching to a modern condensing boiler or heat pump can lower heating costs by 30 % or more. We also help customers access grants such as the Boiler Upgrade Scheme (BUS) and local Green Deal incentives.
Are your engineers certified to handle refrigerants and compliant with UK regulations?
Absolutely. All technicians hold current City & Guilds 2079 (Category 1) F-Gas certificates and are registered with REFCOM. For gas appliances we are Gas Safe-registered, and for electrical controls we employ NICEIC-approved contractors. We follow Part F and Part L of the Building Regulations, comply with Health & Safety Executive (HSE) guidance, and issue all legally required commissioning and maintenance documentation. This guarantees that your system is installed, serviced and decommissioned safely, efficiently and in full legal compliance.
