How important is it to replace aging windows and doors?

Openings such as doors and windows sometimes let in outside air when they are old, poorly installed or damaged (e.g. cracks or holes). This will make it more difficult to create a comfortable temperature inside, especially in winter. In other words, the heating system will have to work at full power to warm your home. This increases your energy consumption, thus inflating your bills.

Therefore, it is important to replace windows and doors in poor condition or of poor quality to improve the insulation of the building. This way, your heating system will be more efficient and will offer optimal performance. In the end, this investment, although it can be substantial, guarantees your comfort, increases the durability of your air conditioning equipment and considerably reduces your expenses in the long run.
