LH HVAC Checklist

Keep your HVAC running smoothly all-year round

LH recommends that a full check-up of an HVAC system be undertaken once a year. Between these checks, commercial and industrial premises facilities managers should be conducting regular maintenance checks for themselves.

1. Replace or clean the filter

The air filter in your chiller or heater is vital to maintaining indoor air quality and system efficiency. Over time, these filters naturally become clogged with dust and debris, which can reduce the system’s ability to circulate clean and conditioned air.

Replacing or cleaning the filter as recommended by the manufacturer – typically every 1-3 months – ensures that the HVAC system operates efficiently, reduces energy consumption, and provides cleaner air.

2. Check and clean the outdoor unit

The outdoor unit, such as a condenser, heat pump or air handling unit, is exposed to the elements and will accumulate dirt. It is important to keep the area around the outdoor unit clear from leaves or overgrown plants. Air ducts and vents should also be inspected for blockages and vacuumed to ensure proper airflow.

If any mould or damage is detected in the ducts, blowers and blades, an HVAC expert should be contacted to address it.

3. Clean the coils and condenser

The evaporator and condenser coils play crucial roles in the heating or cooling process, and if they’re dirty they can struggle to transfer heat effectively. This results in the HVAC system working harder, consuming more energy, and potentially leading to higher bills.

Regular cleaning of the coils and condenser helps your system run efficiently, while also extending the equipment’s lifespan. If you’re unsure how to clean these components, it’s advisable to consult a professional HVAC technician.

4. Test the HVAC controls

To optimise your HVAC system’s performance, its controls must be in full working order and set correctly.

If you’re dealing with an older or outdated controls , it might be time to think about upgrading to the latest smart solutions, which could result in significant energy savings.

5. Check for leaks

Inspecting the cabinet for any leaks in the ductwork or the refrigerant lines can help avoid energy wastage and reduced performance. Refrigerant leaks, for example, can increase the burden on the air conditioning system which will hamper its ability to cool effectively and increase energy bills. If any leaks are identified, a trained technician can help identify and address them.

Following LH’s maintenance checklist on a regular basis will help your HVAC system run efficiently and extend its lifespan between maintenance check-ups by an LH expert.
