Introduction to Residential Furnaces
Residential furnaces are essential for keeping homes warm during the cold Connecticut winters. With a variety of furnace types available, selecting the right one for your home can significantly improve both comfort and energy efficiency. This guide will take you through the options, installation process, maintenance, and financing considerations to help you make an informed decision.

Types of Furnaces Suitable for Connecticut
In Connecticut’s climate, it’s important to choose a furnace that can effectively handle cold temperatures while maintaining efficiency. The most common furnace types include:
- Gas Furnaces: Natural gas furnaces are a popular option due to their affordability and high efficiency. These systems provide reliable heating with lower fuel costs.
- Oil Furnaces: While less common in newer homes, oil furnaces are still an option for many homes in Connecticut. They can offer reliable heating, particularly in areas without natural gas access.
- Electric Furnaces: While typically more expensive to operate, electric furnaces are ideal for smaller homes or when other fuel options are not available.
- Dual-Fuel Systems: These systems combine an electric heat pump with a gas furnace, allowing you to switch between the two for the most energy-efficient operation based on weather conditions.
Choosing the Right Furnace
Selecting the right furnace involves more than just picking a model; it’s important to consider the furnace’s efficiency, size, and the specific needs of your home.
Sizing and Efficiency Ratings
When selecting a furnace, it's crucial to choose the right size for your home. A furnace that’s too small will struggle to heat your home, while a furnace that’s too large can be inefficient. Efficiency is also key—look for furnaces with high Annual Fuel Utilization Efficiency (AFUE) ratings for optimal energy savings.
Common Sizing Mistakes to Avoid
- Overestimating the heating load: This can lead to higher upfront costs and inefficient operation.
- Ignoring insulation quality: A well-insulated home requires a smaller furnace while a more drafty home won’t see heating improvements until a larger furnace is installed.
- Neglecting to factor in window size and placement: Larger windows or poorly insulated windows can impact heating needs causing you to need larger furnaces than necessary.
Single-Zone vs. Multi-Zone Furnaces
Single-zone furnaces provide heating for one area of your home, while multi-zone systems can heat different areas independently. Multi-zone systems can be more energy-efficient, allowing you to customize heating for various rooms.

Customization Options
Furnaces today come with a range of customizable features:
- Smart thermostats for more precise temperature control.
- Variable-speed blowers for quieter operation and better air distribution.
- Zoning systems for tailored heating in different rooms.
