Replacing a 3 ton AC unit and furnace is a significant investment for homeowners looking to maintain comfort and energy efficiency in their homes. Understanding the average costs involved in replacing these HVAC components helps in budgeting and making informed choices. Factors such as equipment brand, installation complexity, and local labor rates can influence the total expense.
| Item | Average Cost Range | Key Factors Affecting Cost |
|---|---|---|
| 3 Ton AC Unit | $3,000 – $5,500 | Brand, SEER rating, installation complexity |
| Furnace | $2,500 – $6,000 | Fuel type (gas/electric), AFUE rating, size |
| Combined Installation | $6,000 – $11,500 | Labor, ductwork, permits, HVAC contractor rates |
Factors Influencing the Cost of Replacing a 3 Ton AC Unit and Furnace
Replacing a 3 ton air conditioning unit and furnace involves several cost variables that homeowners should consider. Equipment quality, energy efficiency ratings, installation requirements, and local labor costs play crucial roles in determining the final price. Additionally, existing ductwork condition and the need for electrical or plumbing upgrades may add to expenses.
Equipment Brand and Efficiency
Premium HVAC brands often come with higher upfront costs but can offer better reliability and longer warranties. The Seasonal Energy Efficiency Ratio (SEER) rating of the AC unit or the Annual Fuel Utilization Efficiency (AFUE) of a furnace also influences price. Units with higher efficiency ratings typically cost more but yield long-term savings on utility bills.
Installation Complexity
The difficulty of installation varies depending on whether the new furnace and AC unit match existing ductwork and electrical specifications. If significant modifications, such as replacing ducts, upgrading electrical panels, or securing permits, are needed, the labor costs will be higher.
Average Costs of a 3 Ton AC Unit Replacement
Replacing a 3 ton AC unit typically ranges from $3,000 to $5,500, including equipment and installation. The price is contingent on several factors like the type of refrigerant used, SEER rating, and brand reliability.
| Component | Average Cost |
|---|---|
| 3 Ton AC Unit (Equipment) | $2,000 – $4,000 |
| Installation Labor | $1,000 – $1,500 |
| Total | $3,000 – $5,500 |
Choosing an AC unit with a higher SEER rating (above 16) might increase equipment costs but offers greater energy savings and potential rebates.
Average Costs of Furnace Replacement for a Standard Home
The cost to replace a furnace generally ranges between $2,500 and $6,000 depending on fuel type, size, and efficiency. Gas furnaces tend to be more expensive up front but are common and efficient for many U.S. homes.

| Furnace Type | Average Cost Range |
|---|---|
| Gas Furnace | $2,500 – $5,500 |
| Electric Furnace | $1,500 – $3,500 |
| Oil Furnace | $3,000 – $6,000 |
Higher AFUE ratings (above 90%) correlate with better fuel efficiency but typically come at greater installation and equipment costs.
Combined Replacement Costs and Potential Additional Expenses
When replacing both a 3 ton AC unit and furnace simultaneously, homeowners can expect to pay between $6,000 and $11,500. Bundling these installations often reduces labor costs compared to separate replacements.
Additional expenses may include:
- Upgrading or repairing ductwork to ensure proper airflow.
- Installing new thermostats, such as smart or programmable models.
- Electrical upgrades to accommodate system power requirements.
- Permitting and inspection fees required by local municipalities.
How to Choose the Right HVAC Contractor
Selecting a reputable HVAC contractor is essential for a quality furnace and AC unit replacement. Licensed and insured contractors with strong local reviews can ensure proper installation, compliance with regulations, and access to manufacturer warranties.
- Request multiple quotes to compare pricing and services.
- Verify credentials such as state licenses and certifications.
- Ask about experience with specific HVAC brands and models.
- Confirm contractor’s policy on permits and inspections.
Energy Efficiency Incentives and Rebates
Many utility companies and government programs offer rebates or tax credits for upgrading to energy-efficient HVAC systems. These incentives can substantially lower the effective cost of replacing a 3 ton AC unit and furnace.
- Federal Tax Credits for high-efficiency furnaces and air conditioners.
- Local utility rebates based on SEER and AFUE ratings.
- Manufacturer promotions during seasonal sales events.
Checking eligibility and applying for these incentives before replacement can maximize savings.
