Furnace and Air Conditioner Combo Cost(How Much Does An Air Conditioner Furnace Combo Cost?)

Furnace and Air Conditioner Combo Cost

Furnace and air conditioner have a limited age. And with new technology advancements, better ac and furnaces are introducing in the market. So replacing an old ac and furnace unit can be a better option.

If you’re thinking about replacing your ac and furnace but don’t know how much will it cost you? Yeah, it can be troublesome for a person who barely knows about ac and furnaces. 

I have been an HVAC technician for about 6 years now and it takes years to finally become a seasoned HVAC technician. So In this guide, I’ll share every detail possible about the ac and furnace combo cost and buying guide.

Furnace and Air Conditioner Combo Cost Tiers

AC and furnaces can be divided into three groups on the basis of efficiency and performance: Basic, Better, Best.

TierFurnace AFUEFurnace TypeAC SEERAC TypeInstalled Cost
Basic80% to 93%Single- Stage13 to 15 SEERSingle Stage$3,600 to $6,000
Better94% to 97%Single or Two Stage16 to 20 SEERSingle or Two Stage$4,500 to $8,250
Best97% to 98.5%Variable – Capacity19 to 26 SEERVariable – Capacity$6,300 to $ 11, 750

1. Basic AC and Furnace Level

Basic is the most affordable ac and furnace combo for any buyer. The basic single-stage furnace has an AFUE rating of 80% to 93%.

AFUE is the ratio of furnace’s/boiler’s annual heat output compared to the total fuel energy consumed by a furnace or boiler.

AFUE of 80% means that 80% of the energy in the fuel becomes heat for the home and the other 20% escapes from chimneys or somewhere else.

In the basic, the SEER rating of an air conditioner is 13 to 15 SEER. For those who don’t know about SEER, it stands for Seasonal Energy Efficiency Ratio.

This SEER rating signifies the ac/heat pump energy efficiency. The higher the number the lesser electricity ac uses.

The installation cost of the basic pack is between $3000 to $6000. The basic ac unit does not cost that much but the operating cost is much higher due to lower efficiency.

Basic furnaces have a single-speed blower motor that runs at a maximum speed when it’s on.     

2. Better AC and Furnace Level

In the better AFUE rating of the single or two-stage furnace is between 94% to 97% which is really impressive. The AC SEER ratings are around 16 and 20 SEER. These types of SEER ratings can save make a huge difference in the energy bills.

A two-stage air conditioner and furnace offer better performance and moderate cost which appeals to homeowners. A two-stage ac and furnace can run on low up to 65% of the time to maximize efficiency and climate control.

However, a two-stage ac and furnace run on high when they detect that a significant boost is required in heating/cooling. The cost of installation is around $4500 to $8250 which is relatively higher than the basic.    

3. BEST AC and Furnace Tier

A Variable-capacity system is the most expensive out of all three. The installation cost of the BEST tier ac and furnace is around $6300 to $11,750. Due to their highly efficient nature, the cost of heating and cooling is really low. 

Best tier furnaces provide 97% to 98.5% AFUE ratings. The SEER rating of the air conditioner is around 19 to 26 SEER.

The initial installation cost is the only less attractive factor of a variable capacity system but they tend to save more in the long run. These systems perform with super efficiency and deliver the best climate control. 

Factors Affecting Price Of Furnace and AC Combo


The bigger the unit the more it will cost it is as simple as that. Central air conditioners range from 18000BTU (1.5Ton) to 60000BTU (5 TON). The 5-ton ac will always cost more in both areas the installation and the efficiency. The furnace range from 45,000BTU To 1,50,000BTU.

Efficiency and Performance

The better the heating or cooling system the more it will cost. Honestly speaking I don’t recommend getting a super-efficient system if you’re using it for the personal home.

The cost you’ll save on the energy bills will be much lesser than the part replacement. Super efficient system parts cost way high and are very expensive to maintain.  

Ease of Installation:

If the place of installation is complex then the cost of installation will go higher. 

Cost of Living In Your City: 

Some cities will have a higher cost of living so the overall installation cost can go way higher. You need to consider that you can try getting quotes from the other city’s companies also. You must always compare different packages from your neighboring cities.

Sizing Your AC and Furnace System:

This is one of the most important steps while buying or replacing the ac or furnace unit. You must know what capacity ac and furnace you need.

If you get an undersized unit it’ll have to overwork to keep the cooling or heating. And if you bought an oversized ac or furnace unit then you’ll end up with high maintenance and energy bills. 

You must check your house square feet and the areas you want cool and other different things like, the climate of your region, how many persons you have in the house, how tall is your ceiling, and other things. Then calculate how many BTUs do you need and then proceed to buy.

Types Of AC and Furnace Combos and Their Cost

Apart from the air conditioner and furnace, there are other choices like heat pump and air handler, and heat pump, and gas furnace.

The average replacement cost of a basic heat pump is between $3,850 and $6,400, whereas the replacement cost of a better heat pump is between $4,925 and $8,785. The high-efficiency heat pump can cost between $6,775 and $12,100.

The dual-fuel system replacement can cost between $4,150 and $6,825 whereas the better dual fuel system can cost between $5,250 and $9,100. The high-efficiency dual fuel system replacement can cost between $7,150 and $12,450
