Furnace Installation 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.
Our Process
- 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 cannot 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 specification’s. 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 and wiring, check and set gas pressure, and then verify the airflow.
- Inspection – Once approved by the inspector, we fire on the system and do our last test and calibrations.

Furnace Installation FAQ
How Long Do Furnaces Last?
This greatly depends on fuel type. Gas furnaces (LP & NG) range 15-20, oil furnaces range 15-25, and 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 biannual maintenance plan where we service both your heating and cooling systems once a year.
How Much Is a New Furnace?
The average cost for furnace installation in North Carolina is $2,500-$6,300 for smaller homes and $3,800-$10,000+ for larger homes. However, each home is different. 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.
How Much Can a New Furnace Save Me?
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 user, 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, and more all play a factor in energy savings.
Does a New Furnace Increase Home Value?
Adding a more efficient HVAC system always adds value to a home, but the amount 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 higher 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.
Is a New Furnace Tax Deductible?
It depends on the state, county, and even the local utility company. Here are some helpful links:
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 and need to purchase a new furnace, though.
A higher-quality system can cost more initially, but it costs less to run & 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.
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, number of 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 will be.
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 (click to view a list of 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.
