Gas Furnaces

Gas furnaces are widely used in Connecticut because they deliver reliable, powerful heat that stands up to harsh winters.

Pros of Gas Furnaces

Gas furnaces provide fast, consistent heating that keeps homes warm even during freezing temperatures. They often have lower monthly operating costs when natural gas prices are steady. High-efficiency models with AFUE ratings above 90% offer excellent performance and long-term energy savings.

Cons of Gas Furnaces

Gas furnaces usually cost more to install, especially if your home doesn’t already have a gas line. Adding gas service requires licensed professional installation and local code compliance. They also require regular maintenance and annual inspections to ensure safety and performance. Because they use combustion, there is always a small risk of gas leaks or carbon monoxide if not properly maintained.

Electric Furnaces

Electric furnaces are easier to install and can be a good choice for homes without existing gas lines.

Pros of Electric Furnaces

Electric furnaces have a lower upfront cost compared to gas models, making them attractive for budget-conscious homeowners. They don’t require gas lines or venting, which simplifies professional installation. With no combustion, they also provide safe operation without the risk of gas leaks.

Cons of Electric Furnaces

Electric furnaces generally cost more to run each month, especially in Connecticut where electricity rates are high. They heat more slowly than gas furnaces, which can be noticeable during sudden cold spells. In very cold weather, they may struggle to keep up with demand, leading to higher energy usage.

Cost Considerations

Gas furnaces are usually more expensive upfront, particularly if installation requires adding gas lines or venting. Electric furnaces are cheaper to install but often lead to higher operating costs in the long run. In Milford, gas is often more cost-effective because of cold winters and high electricity prices.

Local Milford, CT Factors

Long, cold winters: Gas furnaces are especially appealing for fast, efficient heating.

Older homes: Homes without gas lines may find electric systems easier to install. If adding a gas line, licensed installation is required.

High utility rates: Since Connecticut has some of the highest energy costs in the country, efficiency is a critical factor no matter which type of furnace you choose.
