How to Keep Your HVAC Running Efficiently During the Winter Months: Our Top 5 Tips

Top 5 Tips for Maintaining HVAC Efficiency During the UK Winter Months


HVAC maintenance is paramount for having a comfortable, warm home during the winter months. The UK’s winters can always be chilly, but the 2024/2025 winter has been predicted to see colder-than-average temperatures, particularly through January & February with an increased risk of frost and snow, making it more important that home and business owners take the time to ensure their HVAC systems are working exactly as they should be.

1. Schedule Regular Maintenance

Ensure that your HVAC system receives regular maintenance checks. This includes cleaning or replacing filters, checking for leaks, and ensuring that all components are functioning correctly. A well-maintained system runs more efficiently and lasts longer.


2. Optimise Thermostat Settings

Use a programmable thermostat to optimize your heating schedule. Set it to lower temperatures when you’re not home and increase it shortly before you return. This can help reduce energy consumption without sacrificing comfort.


3. Seal and Insulate Your Home/Office

Check for drafts and seal windows and doors to prevent heat loss. Adding insulation to your attic and walls can also help maintain the desired temperature, reducing the workload on your HVAC system.


4. Use Ceiling Fans

In winter, if you have ceiling fans in your home or office space, run the fans in reverse to circulate warm air that rises to the ceiling back down into the room. This can help maintain an even temperature and make your environment feel warmer without increasing the thermostat setting.


5. Consider Upgrading Your System

If your HVAC system is old or inefficient, consider upgrading to a newer, more energy-efficient model. Modern systems use less energy and can significantly reduce your heating bills during the colder months.


 

HVAC Winter Maintenance Checklist


A small amount of effort can greatly ensure a comfortable winter season at your home or business premises. It is increasingly important to take proactive steps in the winter months to prepare your environment for the colder weather. This preparation not only enhances comfort but also promotes safety and efficiency within your living or working space.

Clean/Replace the Air Filters

If the air filters in your HVAC system are clogged, it will have to exert extra effort. The more effort required, the more likely it is to encounter issues. To ensure adequate air supply, clean your HVAC system’s air filters. Simply remove the filter and use a vacuum to clear away dust and debris. Note that some HVAC systems have replaceable filters, which should be replaced according to the manufacturer’s instructions.


Inspect and Clean Ducts and Vents

The efficiency of your HVAC system relies on clean, well-maintained ducts and vents. If these are obstructed, the system will need to work harder to heat your home. Use a vacuum on your vents to eliminate excess dust and debris, but if there’s a significant accumulation, contact a professional HVAC maintenance company such as London AC Technical Services.


Ensure the Thermostat is Working Correctly

To check if your thermostat is functioning properly, perform a simple test. Set it to zero, turn it off, then turn it back on and increase the dial. If it activates, your thermostat should be working as intended.
