How Much Does a New Furnace Cost?

If you want your home to be warm and cozy, you need a furnace that works properly. Like any other appliance, a furnace becomes less efficient over time. Depending on its condition, you may need to repair or replace it. If you’re considering getting a new furnace, several factors affect its cost. In this article, we’ll explore how much a new furnace costs. Let’s get started!

Signs You Need to Replace Your Furnace

Identifying your furnace’s signs can help reduce energy costs and expensive repairs. They are

  • Frequent Repairs: If you frequently call your HVAC experts for repairs, you should get your furnace system replaced. Frequent repairs can be expensive.
  • Age of the Furnace: Furnaces usually last 10-15 years, depending on environmental conditions. So, it’s advised to replace them rather than repair them.
  • Increased Energy Bills: If your heating costs have increased significantly, it may be a sign that you need to replace your furnace with a more energy-efficient model.

Factors That Impact How Much A New Furnace Costs

1. Furnace Manufacturer

The cost of the furnace system will be different depending on the brand. If you are looking for well-known brands, the cost will be higher. On the other hand, lesser-known brands tend to have comparatively lower price tags. Decide yourself by considering your HVAC expert’s suggestions, requirements, and budget.

2. Cost of Installation

Installation and labor costs can significantly increase the cost of replacing a furnace. A new furnace may not be the same size as the old one, requiring ductwork modifications, cleaning, and sealing. The new unit may also not align perfectly with existing gas lines, electrical connections, or vents. High-efficiency models may need additional PVC piping for intake and exhaust, and some wall controls may require extra wiring. Installation costs vary by dealer, and some offer discounts on equipment through service agreements or overstock deals. Ensure that the work is done by a certified HVAC professional instead of a DIY to get the job done correctly.

3. Furnace Efficiency

The cost of a furnace depends partly on its energy efficiency. The higher the efficiency, the higher the price. However, a more efficient furnace can save you money on energy bills. Every furnace in the U.S. must display its AFUE rating, which shows how effectively it converts fuel into heat. You can find this rating on the yellow Energy Guide label, manufacturer websites, or by asking your local dealer.

  • High-Efficiency Furnaces

These furnaces use two heat exchangers instead of one, making them more efficient and expensive. They can lower energy costs over time.

  • Mid-Efficiency Furnaces

These meet the U.S. minimum efficiency standard (80% AFUE) and cost less than high-efficiency models. They have simpler components, like a single heat exchanger and basic controls, making them more affordable upfront.

4. Furnace Size

When referring to the furnace size, it indicates how much heat it can produce. A furnace with more heating power is usually bigger and costs more than one with less power. A professional HVAC expert can help you determine the right furnace size for your home. They will consider your home’s size, ductwork, windows, and insulation. Since prices can vary between HVAC contractors, it’s a good idea to get quotes from multiple professionals to find the best deal on the right-sized furnace.

Cost of New Furnace System

1. Electric Furnaces

Electric furnaces are a great choice for areas with mild weather. The installation is because they need electricity to work. They are more affordable than gas furnaces, but the operational costs may be higher. Replacing an electric furnace usually costs between $2,500 and $4,500.

Pros:

  • Better heat emission
  • Convenient energy source
  • Environment friendly

Cons:

  • Expensive

2. Gas Furnaces

Gas furnaces are the most preferred choice for homes with access to a gas line. Since gas is usually cheaper than electricity, running a gas furnace is more affordable than an electric one. The cost to replace a gas furnace ranges from $3,500 to $10,000, with an average cost of around $7,000.

Pros:

  • Affordable
  • Better heat emission
  • Environment friendly
  • Efficient

Cons:

  • Noisy while starting
  • Unavailability of gas in some areas

3. Propane Furnaces

Propane furnaces are a good option for homes without gas. To replace an old furnace with a propane one, you’ll need enough space for a propane tank. Buying and installing a propane furnace costs $2,500 to $7,500.

Pros:

  • Works without relying on electricity
  • Environmentally friendly
  • It can be easily converted from a natural gas furnace

Cons:

  • Space for propane tank
  • Refilling of the tank needs to be done

Knowing the cost of a furnace and the factors that help you choose the right one for your home is important.
