As energy costs rise and environmental concerns grow, maintaining an efficient home heating system has become more crucial than ever. Your air conditioning (AC) unit plays a significant role in this, not just for cooling but also for heating, especially with modern systems designed for year-round comfort. Ongoing upkeep ensures that your AC runs at optimal efficiency, delivering constant warmth during the colder months. This article outlines five straightforward maintenance tips to help you optimise your AC for efficient home heating in 2025.
1. Schedule Regular Professional Maintenance
While DIY maintenance is beneficial, professional servicing is essential for comprehensive system care. Specialists can identify and resolve faults that homeowners may not notice, ensuring that your system runs at full efficiency.
Benefits of Professional Maintenance:
- Thorough inspection and cleaning of system components. Regular HVAC inspections and cleaning remove dust and debris from components, ensuring efficient operation and prolonging system lifespan.
- Finding and fixing potential faults before they become serious ones. Routine maintenance helps detect and address small HVAC issues early on, avoiding costly repairs and system failures.
- Verification of system performance and efficiency. Airflow, temperature, and pressure are all measured during performance testing to ensure that the HVAC system runs smoothly and efficiently.
Scheduling annual maintenance with a reputable provider of air conditioning service London ensures your system remains reliable and efficient throughout the heating season.

2. Regularly Replace or Clean Air Filters
Air filters are essential for maintaining indoor air quality and ensuring your AC system runs efficiently. Filters accumulate dust and debris over time, limiting airflow and causing the system to work harder, which can result in higher energy consumption and lower heating performance.
Action Steps:
- Regular monthly inspections of your air filters are crucial, particularly during periods of heavy usage, to ensure optimal airflow and system efficiency.
- Filters should be replaced or cleaned every 1-3 months, according to the kind and manufacturer’s requirements. To preserve air quality and system performance, change or clean your filters every 1-3 months, depending on the kind and manufacturer’s standards.
- Changing to HEPA filters can enhance indoor air quality by removing 99.97% of pollutants as small as 0.3 microns.
Regular maintenance of air filters not only enhances heating efficiency but also prolongs the lifespan of your AC system.
3. Clean the Condenser Coils
The exterior unit’s coils used to extract and distribute heat from your dwelling. When these coils are covered with dirt and debris, they can’t effectively dissipate heat, causing your system to work harder and less efficiently.
Action Steps:
- Regularly check your condenser coils annually to ensure they’re free from dirt and debris, which can hinder efficiency and strain your AC system.
- Carefully scrub the coils with a soft brush or using a vacuum cleaner with a brush connection. To clean accumulated dirt from the coils, use a soft brush or a vacuum with a brush attachment, which will improve airflow and performance.
- Ensure that the area behind the outdoor furniture is free of leaves, grass, and trash. Preserve a clear space surrounding your outside unit by removing leaves, grass, and debris to prevent airflow obstructions and ensure peak performance.
Keeping the condenser coils clean ensures optimal heat exchange, improving the overall efficiency of your heating system.

4. Inspect and Seal Ductwork
Leaky ducts can dramatically affect the efficiency of the furnace, resulting in inconsistent heating and increased energy bills. Sealing and insulating ducts can improve system performance and comfort.
Action Steps:
- Regularly examine exposed duct sections for visible damage like gaps, holes, or disconnected joints, as thee can lead to significant energy loss and reduced system efficiency.
- Apply mastic sealant or HVAC-rated foil tape to seal identified leaks effectively, ensuring a durable and long-lasting fix that enhances airflow and reduces energy waste.
- Consider hiring a professional to assess and seal ducts in inaccessible areas. For ductwork located in hard-to-reach areas, such as behind walls or in tight spaces, hiring a professional ensures thorough inspection and sealing, improving overall system performance.
- Adding insulation to ducts in unconditioned areas like attics or basements minimises heat loss, maintaining desired temperatures and enhancing energy efficiency throughout your home.
Correctly sealed and insulating ductwork makes sure warm air arrives at its intended destination, increasing heating efficiency.
5. Optimise Thermostat Settings
Your thermostat settings have a direct impact on your home’s heating efficiency. Effective utilisation can result in significant energy savings while maintaining comfort.
Action Steps:
- Set the furnace to the lowest suitable setting during the winter. Maintain your thermostat at 68°F (20°C) when you’re home and awake during winter. This setting strikes a compromise between comfort and energy efficiency, which helps to cut heating costs.
- When you’re asleep or away from home, lower the thermostat a few degrees. Reduce the thermostat setting by 7–10°F (4–6°C) for 8 hours daily when sleeping or away. This method can save up to 10% each year on cooling and heating expenses.
- Consider using a programmable or wireless thermostat to automate temperate adjustments. Utilise programmable or smart thermostats to automatically adjust temperatures based on your schedule, enhancing comfort and achieving energy savings of up to 10% annually.
Optimising your thermostat settings ensures efficient use of your heating system, reducing energy consumption and costs.
