HVAC Maintenance Winter Checklist

Member News

As we’re approaching Winter, we all want to feel warm and well heated in our homes and workplace. That’s why now is a good time to check our HVAC systems and make sure they’re working at their ideal level.

Read our ‘HVAC Maintenance Winter Checklist’ for our top tips on saving money and energy this winter.


  1. Clean air filters

Dirty air filters reduce the efficiency of your HVAC system.

When you check your air filter, look for build-up and dirt on the filter, as this stops air flowing freely through the system. Even if there isn’t much build up on the filters, it’s a good idea to clean them, or even better replace them, in preparation for winter.

Filters should be checked regularly, we recommend every month, and replaced at least every 3 months.

  1. Clean vents

When you check the air filters, it’s also a good time to check the vents. Dirty vents can cause problems such as spreading dust or mould in your home, and anything that’s blocking the vents can reduce the efficiency of the system.

Make sure that the vents are cleaned and free from obstructions, such as furniture or equipment to prevent this.

  1. Clean coils

Both the condenser and heating coils should be clean. Build up on the coils forces them to work harder and the airflow, cooling capacity and pressure are reduced. This results in a loss of performance and efficiency, so energy consumption and running costs are increased.

Some systems may need professional cleaning. At PPS we can service Gas Fired Equipment and Heat Pump units.

  1. Check dampers

Dampers control the flow of air inside your system.

It is a good idea make sure dampers are working before winter, as they can be used to cut off air conditioning (heating or cooling) to unused rooms. This helps to save energy and money on your HVAC system.

  1. Reprogram thermostats

As it’s getting colder, it’s an ideal time to reprogram your thermostat. If you have a programmable thermostat, you can lower the temperature during times when no one is home. This saves both money and energy.

We offer some thermostats and can also work on BMS (Building Management Systems).

A note on ventilation and COVID-19

As stated by the HSE “good ventilation can help reduce the risk of spreading coronavirus” – the key is ensuring there is an adequate supply of fresh air.

The Chartered Institution of Building Services Engineers (CIBSE) have reviewed their COVID-19 Ventilation Guide as we enter the ‘heating season’…

“During the heating season it will be necessary to balance the benefits of increased ventilation rates against the need to maintain the thermal comfort of the occupants. This guidance takes a risk averse approach to reducing indoor pollution without significant capital cost and is subject to change as transmission routes become more clearly defined.”
