Winters are cold in Lewes, DE, and a forced-air furnace is a popular option for many homes trying to keep warm. They’re economical and easy to use, which makes them the go-to choice when installing a new system. But furnaces are further subdivided between gas-fed units and those that use electricity to run. If you’re preparing to buy a new furnace, it behooves you to understand the benefits and drawbacks that each one offers. Every home is different and the type that works best for you depends on your particular circumstances. It pays to consult with a trained expert when making your decision.
Should You Replace Your AC and Furnace Together?
Replacing your AC and furnace together can be a smart choice when both systems are aging or inefficient. Benefits can include:
- Better system compatibility between heating and cooling equipment
- Improved energy efficiency and more consistent comfort
- Fewer repair issues from pairing new equipment with an older system
- Lower long-term replacement costs by completing both upgrades at once
- Easier installation, since both systems can be sized and matched together
This option is especially helpful if your furnace and AC share components, such as the blower motor or indoor air handler. Replacing both systems together can also make it easier to choose equipment that fits your home’s comfort needs and energy goals.
Pros and Cons of Gas Furnaces
Gas furnaces are more common, largely because they’re less expensive to operate from month to month. (Natural gas costs less than electricity.) They also tend to heat the home more quickly, which can be a significant concern on a cold day. On the other hand, installation is usually more expensive, since the unit needs to be connected to gas lines, and if you live in a rural area, you might not have that option. Gas furnaces tend to suffer more wear and tear than electrical units as well, which means a great chance of breakdowns and increased repair bills.
Pros and Cons of Electric Furnaces
Electric furnaces benefit by being able to operate without a gas line, which makes them ideal for homes located outside the civic grid. Accordingly, they cost less to operate and can function so long as your home has electricity. They suffer less wear than gas units, meaning that they will last longer on the whole. The difficulty comes mainly in monthly costs, which are higher than comparable gas units, and in the fact that they take longer than gas units to warm the home.
Frequently Asked Questions
Question: What is the main difference between a gas and electric furnace?
Answer: A gas furnace burns natural gas to create heat, while an electric furnace uses electrical resistance to warm the air. Both can heat a home effectively, but they differ in installation needs, energy costs, maintenance, and safety considerations. The better option depends on your home, budget, and local utility rates.
Question: Is a gas furnace or electric furnace cheaper to install?
Answer: Electric furnaces are usually less expensive to install because they do not require gas lines, venting, or combustion equipment. Gas furnaces often cost more upfront, but they may have lower operating costs in areas where natural gas is affordable. Homeowners should compare both installation and long-term energy expenses.
Question: Which furnace type is more energy efficient?
Answer: Electric furnaces are highly efficient at converting electricity into heat, but electricity can cost more than gas in many areas. Gas furnaces may lose some energy through exhaust, but high-efficiency models can still provide strong performance. True efficiency depends on equipment quality, fuel prices, climate, and home insulation.
Question: Does a gas furnace need more maintenance than an electric furnace?
Answer: Yes. Gas furnaces typically need more maintenance because they use burners, gas valves, heat exchangers, and venting systems. These parts should be inspected for safe operation. Electric furnaces have simpler components, but they still need routine service to keep airflow, controls, and heating elements working properly.
Question: How do I decide between a gas and electric furnace?
Answer: Start by looking at whether your home already has gas service, what local energy rates are like, and how much heating power you need during winter. A heating professional can compare comfort needs, installation costs, safety factors, and long-term operating expenses before recommending the best furnace option.
