How Much Does A New HVAC System Cost?

New HVAC system costs

The heating, ventilation, and air conditioning systems keep the home warm during cold, cool in the summers, and circulate fresh air throughout to stop the spread of allergens. Most HVAC systems can last up to 15 and some to 20 years. However, if your HVAC is old or cannot function properly, it’s time to replace it. How much do HVAC systems cost? Well, on average, the replacement cost is approximately $6,775 – $12,130.

HVAC systems are imperative and add up to the comfort of the house. A poorly functioning unit will be of no use and only shoot up the energy bills and even make your house uncomfortable. While it can be expensive to replace an HVAC system, it doesn’t have to be stressful if you take the proper time to do the research. The relevant information includes the potential cost and ways to manage this expense.

Top Things That Influence the HVAC Unit Replacement Cost

Several things influence HVAC unit replacement costs. Prices can differ from nation to nation because of labor prices, installation, cost of new units, removal and disposal fees, and the home’s condition.


Labor can cost anywhere between $500 – $2,500 USD, depending on your state. The main factor, in this case, is the installation’s size and difficulty, along with the average hours involved in the job.

On average, this job can take anywhere from 6 to 10 hours if the HVAC system is changed with a new one. But, if there is a need for ductwork, the installation can extend as long as three days.

Size Of The House

One of the factors that influence the selection of a new HVAC system is the size of your house. It will determine the square footage the HVAC system will need for heating or cooling down your place. If your house is large, you might want to consider adding up another HVAC unit.

Another thing that plays a vital role in deciding which system is optimal is the home’s construction. With less insulation, you might have to go for a unit with higher air conditioning and heating capacity.

If there’s improper insulation, the HVAC system will require you to work much harder to keep your place cooled or heated. Research accordingly or ask a professional for details to help you make the final decision.


Ductwork is responsible for transporting heat or cooled air throughout the house. It gets priced by quantity, costing $10 – $35 per linear foot.

One thing that determines the total cost is the selected material, whether new vents are required, and the house’s layout and size. If you want the duct to remain hidden and encased, an extra cost is involved.

Your existing ductwork might be enough for a new HVAC system. But, if it needs replacing or an extension, prepare for significant extra financial costs. New ductwork can be $3,000 for proper installation, impacting the overall bill.

HVAC’s Unit Brand

Go for an HVAC unit that can provide you with the maximum usage and also help to reduce energy bills. Researching properly will make a difference and protect you against any mishaps in the future. The popular and reliable HVAC brands will never compromise on quality and always provide the best.

Five Signs It’s Time To Replace The HVAC Unit

An HVAC unit will last up to 20 years. As the unit ages, it wears out with usage and becomes less efficient, requiring more maintenance which can get expensive. A few signs that it’s time to replace the HVAC system are the unit’s age, expensive utility bills, strange noises, and excessive dust. Let’s talk about each one in more detail below.

1. Higher Energy Bills

Energy bills can differ widely from one season to another. However, the bill should not have a significant difference compared to the same month from previous years.

If you notice that your energy bill is very different from the same time last year, it’s probably time to replace the unit. With so many energy myths out there, it’s important to figure out the reality and what needs to change for maximum efficiency.

2. Inconsistent Home Temperature

An aging HVAC unit will not be able to keep a consistent home temperature. If you notice the home isn’t warm enough in the winter or cold enough in the summer, the HVAC system might not be working properly anymore. There can be many reasons, such as cracked ducts and clogged filters.

3. Noises

A failing HVAC system will make a lot of grinding noises. But, a properly maintained HVAC system will run quietly. If there are unusual noises, you will need professional help.

4. System’s Age

As a homeowner, you need to know that many professionals recommend replacing a home HVAC system every 10 or 15 years for maximum efficiency. Different parts of the system have different ages and vary according to usage.

The average lifespan of a heat pump can be somewhere from 10 to 20 years, while the furnace’s lifespan can be between 15 to 30 years. The air conditioning unit can last up to 20 years. However, regular maintenance can increase the system’s average lifespan and extend its life.

5. Dust In The Home

An HVAC unit heats and cools your space while reducing allergens in the home. If it is not working properly, you may notice more dust in the house than in previous years.


Now that you know the prices of a new HVAC system and the common factors influencing its price, act accordingly. It could be that a few parts need replacing, rather than the entire unit, or it simply needs general servicing.

Speak with an HVAC service professional before proceeding further to get expert advice. Asking the right questions will allow you to make the right decision for your home.
