What is heat recovery ventilation?

Heat Recovery Ventilation (HRV) provides continuous fresh air by exchanging stale indoor air with filtered outdoor air, while recovering most of the heat from the outgoing air to condition incoming air.

How does HRV save energy?

An HRV unit transfers heat from the outgoing air to the incoming air via a heat exchanger, recovering typically 60–95% of the thermal energy and reducing the need to reheat fresh air.

Do I need ducts installed in my home?

Yes—ductwork is required to supply and extract air from rooms such as kitchens, bathrooms, bedrooms and living areas.

Where is the HRV unit installed?

Typically in a utility room, garage or cupboard—inside the insulated envelope and centrally located for easy access to filters and maintenance.

What are the health benefits?

HRV removes moisture, dust, pollen, VOCs and odours 24/7, reducing mould risk, improving air quality and benefitting people with asthma and allergies.

Is it suitable for all homes?

HRV is ideal for well‑insulated, airtight modern homes. It works independently of heating systems, but your home should be well sealed to maximise efficiency.

Building Facilities Management in Ireland

Building Facilities Management

Precision Mechanical is a Cork-based leading building management company covering all aspects of building management putting a deep focus on the core complex systems within buildings to ensure your building is running as safely and efficiently as possible.

At Precision, we build and implement a tailor made building management programme specific to the building's design and needs ensuring all current regulations are being upheld and documented regularly, protecting our clients from exposure in insurance audits, fire officer reports and any other reasons that could put our clients at financial or legal risk.

Our main priority is to ensure all life safety systems are maintained quarterly and documented. All sprinklers, dry risers, wet risers, fire extinguishers, fire alarms, fire smoke dampers and smoke shaft ventilation systems and more are tested, checked and documented thoroughly.

Life safety systems management

All life safety systems maintained and tested. This is essential for every building to maintain current codes of practice.
Fire alarm systems, Fire extinguisher checks and maintenance.
Dry riser testing.
Fire smoke damper maintenance.
Smoke shaft and AOV maintenance.

Preventative maintenance

All plant such as pumps, boilers, heat pumps, A/c systems, valves, chillers, fans and BMS systems will be serviced and records documented to make sure warranties are maintained and unexpected breakdowns are kept to a minimum.
Upkeep and running of water softener systems on a weekly basis adding salt to systems to prevent limescale build up.
Legionella monitoring checks consist of water temperature checks that are recorded across buildings on a bi-weekly basis and analysis of the BMS systems to ensure all graphs recording the correct temperatures, water tank cleaning is usually done every 6 months, strainers are pulled and cleaned across the building.

All ventilation systems are inspected and cleaned on a regular basis with flow rates being checked on a regular basis.
The BMS can be linked to our phones ensuring whoever is on call will receive any system alarms immediately ensuring a fast response time.
By taking a proactive approach to maintenance, we help our clients optimise the performance and longevity of their mechanical systems, minimising downtime and ensuring a safe, comfortable, and efficient environment for all building occupants.

Intelligent energy building solutions

We are passionate about optimising a building's energy efficiency to minimise energy consumption. With current energy costs it is imperative that every system is running at optimum efficiency, working with us will lead to a reduction of carbon emissions.
At Precision Mechanical we are ideally positioned to optimise your energy assets, by developing energy efficient initiatives or through operational cost reductions.
We offer seamless execution and delivery of energy upgrades.
