Furnace Installation in Wake Forest, NC


What does a furnace installation cost?

It depends. You can’t just put any furnace in your home and expect it to keep you warm. According to NC State Law, every furnace system must go through various tests and calculations. The average cost for furnace installation in North Carolina is $2,500-$6,300 for smaller homes and $3,8000-$10,000+ for larger homes. Here’s how we determine the total cost of your furnace system and installation:

Home Size

Does home square footage increase my furnace installation cost?

Furnaces work by heating and circulating the air in your home. Home square footage, ceiling height, stories – all of these things affect what type of unit you need. Generally, the bigger the home and more stories, the bigger and pricier your system.

Fuel Type

Does fuel type affect furnace cost?

Furnaces can run off of oil, gas, electricity, and several other fuel types. The type of furnace you select will greatly affect the cost of the unit. Each fuel type has pros and cons. Currently, natural gas is the cheapest, but it must be piped into your home from a provider. Here are some natural gas providers in Central NC. Propane costs more, but doesn’t require piping –  it just needs a tank and delivery. And electric heat (like heat strips) is currently very costly because of the cost of electricity.


Why does sunlight affect furnace cost?

Different types of roofs, tree cover, siding, windows, and colors affect just how much and how quickly the sun heats your home. The more sunlight that hits your home, the less heat you need from your furnace. More or less sunlight can make a big difference in your monthly energy bill!


How does insulation affect furnace cost and efficiency?

A good coffee mug will keep your coffee hot for hours – the same goes for your home! Poor quality insulation allows the heat in your home to escape, meaning you need a bigger and pricier system that needs to run longer, ultimately increasing your energy bill. 


Why does occupancy matter when it comes to furnace installation?

People generate heat. Depending on how many people, how long they’re inside, and how frequently they cook and shower, that will affect how hot your home gets. This results in you needing a bigger and pricier system that has to run longer, increasing your energy bill.

Unit Quality

Does furnace quality matter?

A lower quality system is cheaper to buy, but more expensive to run and service, and usually has a shorter lifespan. It can work well if you’re on a tight budget to purchase a new furnace, though.

A higher-quality system can cost more initially, but it costs less to run and service and has a longer lifespan. Generally, getting a better quality furnace with higher AFUE can be cheaper over the total life of the unit.

AFUE stands for ‘Annual Fuel Utilization Efficiency’ ratio, and it measures what percentage of fuel is burned. So a 97% AFUE system only wastes 3% of fuel. But less efficient units have an AFUE closer to 60%-70%, and wastes 30%-40% of fuel. A higher AFUE means higher efficiency and lower monthly bills. An average propane gas (LP) heating bill in NC is around $114 for natural gas (NG) heating it’s about $55.

Other Appliances

Do other appliances affect my HVAC system?

Larger appliances such as ovens, generators, TV’s, and computers all generate heat. And each one generates heat in a different zone of your house, which means you need different amounts of heating or cooling in each zone. The location and use of these appliances affect system size, location, and design.


Does warranty affect cost?

Finding a furnace system with a good warranty or purchasing one from a dealer can help reduce costs from repairs and yearly maintenance. Some systems come with just a few years warranty on parts. And some HVAC companies only warranty labor for up to 1 year.

Our American Standard systems have a variety of warranty options. Plus, we offer a 2-year labor installation warranty!

Total Cost of Ownership

If you want the best overall value, then you need to know the total cost of ownership. In other words, what is the total cost of the furnace installation, service, maintenance, lifespan, and energy. Ask yourself:

How long do furnaces last?

This greatly depends on fuel type. Gas furnaces (LP & NG) range 15-20, Oil furnaces range 15-25, electric can last up to 30 years. All of the ranges HIGHLY DEPEND on unit quality, fuel type, usage, installation quality, and maintenance.

An improperly installed furnace can break down quickly. Risks like faulty wiring or gas lines can cause a system or even a home to burn up. And a lower-quality system may not last as long. However, with proper furnace installation and maintenance, it may last longer.

How often should a furnace be serviced?

Recommended once a year. As your furnace burns fuel, it creates soot on internal parts. Luckily, furnace installation with Casey Services comes with one year of free maintenance. Routine maintenance mitigates the risk of larger, more expensive repairs and keeps your system running efficiently. Additionally, it increases the safety of your unit by reducing the risks of gas leaks. We offer a bi-annual maintenance plan where we service your heating and cooling systems once a year.

How much can an energy efficient furnace unit save each month? Each year?

Older systems run on a much lower AFUE rating. If your unit is 65% AFUE and you switch to an 95%, that’s 15% savings right there. For the average LP users, it works out to be about $410 a year and $200 for NG. Knowing the AFUE rating of your old system will help you make the calculation more accurate. Beyond the rating things like, ductwork, insulation, sunlight, plus others all play a factor in energy savings.

How much value will a new furnace add to my home?

Adding a more efficient HVAC system always adds value to a home, but how much can vary. Home appraisals have a section dedicated to energy efficiency. In North Carolina, if a home is certified energy efficient they are more likely to sell and at a high value per square foot than a less energy efficient home. With the higher AFUE system your home could be worth more.

Other existing HVAC features also play a part. For example, having good home insulation and well insulated ductwork can be a major value add as it helps increase efficiency.

Does my furnace qualify me for tax credits?

It depends on the state, county, and even local utility company. Here is a helpful link:

Company and Process

“If you think it’s expensive to hire a professional, try hiring an amateur.” The price tag on a faulty furnace installation can become much higher than you think! Loss of warranty or insurance coverage, permanent damage to the unit or your home, and hours of headaches can be easily avoided by hiring an expert.

Furnace Installation Process

With thousands of furnace installations under our belt, Casey Services knows the drill. We’re trained problem solvers and know exactly what tools, equipment, and skills are needed to do the job right — the first time.


  • Load Calculation – We do load calculations based on the major factors affecting a home like size, insulation, sunlight, etc. These calculations are often referred to as Manuals J, S, T, & D.
  • Consult – We discuss the HVAC needs of the home, as well as the comfort, energy savings, and system lifespan with the homeowner.
  • Permits – We pull all necessary permits. Without the proper permits, your system can not be inspected by the county. Also, in case of an electrical or system fire, insurance companies won’t cover any possible damages to your home. And usually system manufacturers will not warranty an unpermitted furnace installation.
  • Removal – We remove your old furnace (if there is one) and recycle the unit for parts.
  • Furnace Installation – We install the new system per the manufacturers specifications. No cutting corners, skipping valuable tests, or trying to skimp on materials like nitrogen or solder. This is very important – if the system is not installed properly, it will leak repeatedly and suffer serious problems.
  • Test: We examine the system’s gas pipes, wiring, check and set gas pressure, and then verify the air flow.
  • Inspection – Once approved by the inspector, we fire on the system and do our last test and calibrations.
