A furnace is a key component of any home’s heating system, ensuring that residents stay warm and comfortable during the colder months. However, over time, furnaces wear out and need to be replaced. Whether you're dealing with an old, inefficient unit or an unexpected breakdown, replacing a furnace is a significant home improvement project.

A furnace blowing cold air can be a frustrating experience, especially during the winter months when you rely on it to keep your home warm and comfortable. Understanding why your furnace might be blowing cold air is crucial for diagnosing the issue and finding the appropriate solution.

Choosing the right size furnace for your home is critical to ensuring optimal comfort, energy efficiency, and system longevity. A furnace that is too small will struggle to heat your home, leading to increased energy consumption, while a unit that is too large will cycle on and off too frequently, which can lead to wear and tear and inefficiency.
