HVAC

At PM Technical Services, our HVAC Support & Maintenance services are engineered to ensure optimal performance, energy efficiency, indoor air quality, and long-term reliability of your heating, ventilation, and air conditioning systems. We deliver comprehensive proactive and reactive support, including: fresh air intake testing, system air balancing, ductwork installation, and integration of VAV units, dampers (volume control, fire, and smoke), and associated components—integrated seamlessly with water hygiene and mechanical services where required.

Our tailored programmes are designed to minimise downtime, reduce energy consumption, enhance occupant comfort, improve ventilation rates, and maintain compliance with relevant standards such as CIBSE guidelines, Building Regulations Part L, DW/144 for ductwork, and health & safety requirements. Led by our directors, who collectively bring over 20 years of hands-on engineering experience in HVAC servicing, system optimisation, installations, and multidisciplinary building services, we provide technically precise solutions for commercial, industrial, healthcare, and residential properties.

Our mobile teams ensure efficient, minimally disruptive service delivery across your facilities.

In-Depth Engineering Features of Our HVAC Support & Maintenance Services

Proactive Maintenance Programmes

Scheduled engineering regimes focused on prevention and optimisation:

Detailed inspections, performance testing, and trend monitoring of system parameters (e.g., airflow rates, temperature differentials, refrigerant pressures).
Coil cleaning, filter media assessment, and component lubrication to maintain heat transfer efficiency and airflow.
Energy audits and calibration of controls for boilers, chillers, AHUs, and FCUs to maximise operational efficiency.

Fresh Air Intake Testing and Ventilation Assessment

Comprehensive evaluation of fresh air systems to ensure adequate outdoor air supply, compliance with ventilation rates (e.g., per CIBSE Guide B), and prevention of indoor air stagnation. This includes airflow measurement at intakes, filter condition checks, and CO2/pressure differential monitoring for optimal indoor air quality.

Air Testing and Balancing (TAB)

Proportional balancing using certified instruments (e.g., anemometers, pitot tubes) to achieve design airflow rates across terminals, branches, and mains. We perform duct traverses, adjust dampers, and verify system totals for even distribution, reduced noise, and energy savings.

Reactive and Emergency Support

Rapid response to system faults, breakdowns, or performance issues: refrigerant leaks, fan motor failures, control malfunctions, or uneven temperature distribution. Our engineers provide on-site diagnostics, component repairs/replacements, and system reinstatement with minimal operational impact.

Compliance and Risk Management

Rigorous health & safety protocols including Risk Assessments and Method Statements (RAMS), COSHH for refrigerants/chemicals,

F-Gas compliance for refrigerant handling, and working-at-height procedures. We conduct audits, maintain service logs, and ensure systems meet air quality, energy performance, and fire safety standards.

Specialised HVAC System Maintenance and Installation

Air Handling Units (AHUs)

Comprehensive servicing including coil cleaning (heating/cooling), fan and motor alignment/checks, belt tensioning/replacement, damper operation verification, and heat recovery wheel maintenance for enhanced energy efficiency.

Fan Coil Units (FCUs)

Filter cleaning/replacement, coil descaling and disinfection, drain pan cleaning to prevent condensate issues, fan impeller balancing, and valve/actuator testing for precise temperature control.

Boilers and Chillers

Efficiency checks, combustion analysis (for gas boilers), waterside inspections, refrigerant circuit testing (for chillers), pump and valve servicing, and scale/corrosion prevention treatments.

Ventilation Systems and Ductwork

Ductwork inspection and installation (sheet metal, flexible, or insulated types to DW/144 standards); mechanical cleaning; fogging disinfection for microbial control; filter replacements.

Installation and commissioning of Variable Air Volume (VAV) units, volume control dampers, fire dampers, and smoke dampers for zoned control, fire compartmentation, and precise airflow regulation.

Monitoring and Reporting

Data-driven analysis including airflow/pressure logging, energy consumption trends, and fault diagnostics - delivered via detailed reports with recommendations for upgrades or efficiency improvements.
