In winter the landscape of your garden may prevent your house from getting the sunshine's warmth. Sunlight can warm homes even during winter.
It warms up the space by reflecting light through windows.
But, there are some homes that contain vegetation which is growing right next to themor high trees in the area that blocks the sun's rays that fall on the home.
High trees prevent the sunlight from entering through the walls and windows. Therefore, the furnace must generate all of the energy needed to heat the space. There is no way to capture the heat from the sun.Your HVAC system is too old
The HVAC system should be able to last between 15 and 25 years. Then, it needs to be replaced. Efficiency of the HVAC unit will depend on the kind and the age of the system. Furthermore, the degree to which it was kept in good condition throughout its lifespan will impact the length of its life.
Incorrect maintenance may drastically decrease the HVAC equipment's service life due to the increased wear and tear of the components. The HVAC system will consume more energy in order to achieve the necessary temperature when the elements are not functioning properly. This extra energy use could be what's causing the increase in your bill.
It is important to clean regularly the HVAC's filters regularly. If they are blocked, the HVAC filter may reduce the efficiency of your air and lead to serious harm to the other components.
You may consider replacing your unit. HVAC systems are costly to replace, but if you consider the constant expensive energy bills you'll have to cover, you will realize that lower utility bills will help offset a portion costs associated with replacing. Particularly when you consider that newer models are more efficient in energy usage than older models. Expect a 20.
