The three most common types of residential furnaces are Gas, Electric, and Oil. Each offers distinct benefits based on your local climate, fuel availability, and long-term energy budget.
Here are the most popular furnace types:
Natural gas is usually the cheapest way. Even with higher gas prices, a heating system fueled by natural gas is typically less than electricity, propane, or heating oil. Energy efficiency is another way to assess the cost of a heating system. An energy-efficient heating system saves you money on your heating bill.
The heat exchanger is often considered the most costly part of a furnace to repair or replace. It is a critical component that transfers heat from the combustion process to the air that circulates throughout your home. Over time, heat exchangers can crack due to the constant heating and cooling cycles they undergo.

Most furnace issues stem from a few common culprits. The easiest to check yourself are clogged air filters and thermostat errors, which usually cause the system to blow cold air, run inefficiently, or cycle on and off constantly. Other frequent problems include dirty flame sensors or failing blower motors.
Set your thermostat to 𝟔𝟖 ∘𝐅 while awake and home. For maximum efficiency and savings, lower the temperature to 𝟔𝟎 ∘𝐅 – 𝟔𝟒 ∘𝐅 while sleeping or when away from the house for the day.
A dirty air filter is the most common cause of short-cycling. If the air filter is clogged with dirt, it won't allow proper air flow to the heat exchanger. That can cause the furnace to overheat and forces the high limit switch to shut the furnace off.
Average Cost to Replace a Furnace
However, the cost of furnaces can range widely depending on their size, type, and efficiency, and homeowners can generally expect a new furnace to cost anywhere between $3,800 and $10,000. If efficiency is important to you, high-efficiency models can reach up to $12,000.
