What our customers say
HEP Ventilation and Air Quality Expertise in Manchester
The distinctive climate in Greater Manchester, shaped by Atlantic airflow, urban density and the legacy of industrial activity, demands a specialist approach to heating, air-conditioning and ventilation. HEP delivers that specialist approach every day, integrating technically robust HVAC engineering with a deep understanding of local building stock, from Victorian terraces in Chorlton to contemporary glass-fronted offices in Spinningfields. By focusing on ventilation and indoor air quality as the core of all HVAC decisions, HEP safeguards occupant comfort while optimising system efficiency and regulatory compliance.
Manchester’s eclectic mix of heritage structures and new-build developments poses unique thermal and airflow challenges. Solid-wall construction, limited roof voids, mixed-mode façades and high internal heat gains each affect how fresh air is introduced, tempered, filtered and extracted. HEP engineers begin every project with a forensic building analysis, establishing airflow pathways, infiltration rates, contaminant sources and occupancy profiles. That data-rich approach underpins tailor-made systems that deliver consistent temperatures, balanced humidity and notably healthier indoor environments.
Comprehensive Heating and Air Conditioning Solutions

Proactive interventions minimise emergency call-outs, safeguard warranty terms and protect occupant wellbeing.
Retrofit and Upgrade Projects
Ageing plant rooms across Manchester’s red-brick mills, converted warehouses and post-war office blocks often struggle with rising energy costs and changing occupancy patterns. HEP upgrades equipment in situ, phasing works to avoid tenant disruption. Typical measures include:
- Replacing fixed-speed compressors with inverter-driven alternatives
- Adding energy-recovery wheels to existing air handling units (AHUs)
- Converting electric heaters to air-source heat pumps
- Integrating thermal storage to shave peak demand
These retrofits slash carbon output while providing tighter control of airflow and humidity.
Ventilation Strategies Tailored for Manchester Properties
Mechanical Ventilation with Heat Recovery (MVHR)
Manchester’s urban air can carry elevated NOx and particulate levels, yet comfort-driven occupants demand steady fresh-air volumes year-round. MVHR systems introduced by HEP achieve this by:
- Recovering up to 90 % of outgoing heat to temper incoming air
- Employing counter-flow exchangers to prevent cross-contamination
- Implementing frost protection algorithms during cold Pennine snaps
- Allowing night-purge modes to flush heat buildup from highly glazed spaces
The result is superior IAQ without the penalty of increased heating bills.
Demand-Controlled Ventilation for High-Occupancy Spaces
Meeting rooms, lecture theatres and open-plan offices experience variable occupancy peaks. HEP deploys demand-controlled ventilation (DCV) that modulates airflow based on real-time CO₂ levels, VOC concentrations and humidity. Benefits include:
- Responsive adjustment that curtails energy waste when rooms are vacant
- Enhanced cognitive performance linked to lower CO₂ levels
- Reduced noise because fans operate only at the speed necessary to meet demand
Kitchen, Bathroom and Utility Extract Systems
Moisture-laden, odorous or grease-filled air requires dedicated extract routes. HEP designs specialist ventilation to:
- Capture effluent at source with canopy hoods in commercial kitchens
- Isolate wet-room moisture to curb mould growth in residential apartments
- Incorporate interlocked make-up air supply to prevent negative pressure drops
- Use grease-rated ducting and fire-rated dampers to support building safety strategies
Indoor Air Quality Services Focused on Health and Productivity
Advanced Filtration and Air Purification
Airborne pollutants threaten respiratory health, especially in urban corridors adjacent to major routes such as the Mancunian Way. HEP combats pollutants through multi-stage filtration:
- G4 or M5 pre-filters intercept coarse dust and fibres
- F7 or F9 fine filters tackle PM₂.₅ particulates
- Activated carbon cells adsorb odours and volatile organic compounds
- Optional UV-C or plasma air purification neutralises pathogens
Filter selection is guided by local air monitoring data and building usage, ensuring cost-effective protection without over-specification.
Humidity Management and Condensation Control
Manchester’s relative humidity can swing wildly, with damp Atlantic air mass in winter and dehumidified interiors during heated periods. HEP integrates:
- Desiccant dehumidifiers for archive rooms and galleries
- Adiabatic humidifiers for server rooms and timber-floored theatres
- Dynamic sensors that report dew-point proximity to building management systems
Controlling humidity preserves fabric integrity, deters dust mites and maintains comfort for occupants.
Allergen, Odour and Pollutant Mitigation
Beyond particulate removal, HEP addresses a spectrum of airborne irritants:
- Photocatalytic oxidation cells that break down odorous organic molecules
- HEPA zones for medical suites and clean manufacturing cells
- Ozone-safe ionisers that cluster fine particles for easier filtration
- Source capture arms for vehicle exhaust in underground car parks
Each strategy is engineered to dovetail with existing ventilation without introducing pressure imbalances.
