Keeping your home comfortable in winter and summer can drive up your electricity bill—but are you spending more than you should? Small, everyday mistakes can make a big difference in energy consumption and often go unnoticed. Discover five common mistakes and how to avoid them.
1. Choosing the wrong equipment
Not all HVAC systems are suitable for every space. An undersized unit will have to work constantly to reach the desired temperature, while an oversized one can cause unnecessary spikes in energy consumption. The best approach is to get a professional assessment to choose the best solution for your home or business.
2. Not performing regular maintenance
Dirty filters, worn components, and misaligned systems reduce the equipment’s efficiency. Periodic maintenance ensures efficient operation, extends the system’s lifespan, and improves indoor air quality.
3. Ignoring thermal insulation
There’s no point in having a good HVAC system if the house isn’t well insulated. Gaps in doors and windows, poorly insulated walls, and poorly sealed roofs let heat escape in the winter and enter in the summer, placing a greater demand on the HVAC system and increasing energy consumption.
4. Setting extreme temperatures
Setting the air conditioner to 16°C in the summer or the heating to 28°C in the winter forces the equipment to work at maximum capacity. The ideal temperature for comfort and efficiency is around 21–22°C in the winter and 24–26°C in the summer.
5. Using HVAC without automation
Technology can be a great ally in saving energy. Programmable thermostats, temperature sensors, and smart systems automatically adjust the equipment’s operation according to actual needs, preventing waste when the house is empty or during the night.
How to reduce energy consumption?
Avoiding these mistakes can make a big difference on your electricity bill. In addition, choosing efficient HVAC solutions—such as heat pumps and fan coil units—and combining them with solar energy can make your home more sustainable and economical.
