Installing Central Air in a House Without Ducts: A Homeowner’s Guide Featuring the Goodman 3 Ton 14.5 SEER2 R32 Bundle

INTRODUCTION — CAN YOU REALLY INSTALL CENTRAL AIR WITHOUT DUCTWORK?

If you’ve ever wondered about installing central air in a house without ducts, you’re not alone. Many homeowners find themselves in a tough spot: their homes are old, charming, and efficient in their own way — but they were never built with ductwork in mind. The result? No easy way to add traditional central heating and air.

You may have typed queries like:

• AC without ductwork

• Air conditioner no duct work

• Cost to install central heat with no existing ductwork

• Cost to install central heat and air without existing ductwork

…and quickly realized there’s a lot of conflicting information online. Some sites make it sound simple. Others make it sound impossible.

I’m here to give you the straight truth. There are solutions for homes without existing ducts — and some of them are surprisingly DIY-friendly. But the smart move, especially if you want long-term reliability and efficiency, is pairing these options with a high-performance system like the Goodman 3 Ton 14.5 SEER2 R32 bundle.

CHAPTER 1 — WHY SOME HOMES DON’T HAVE DUCTS

Older homes, cottages, or houses built before the 1970s often didn’t include ductwork because:

• Heating was provided by radiators, baseboards, or wood stoves.

• Air conditioning wasn’t standard; window units sufficed.

• Open-concept designs relied on fans rather than ducts.

The challenge is clear: adding a traditional forced-air system means running new ducts through walls, ceilings, or floors — an expensive and invasive process. That’s why many homeowners start asking about AC without ductwork or air conditioner no duct work options.

CHAPTER 2 — OPTIONS FOR CENTRAL AIR IN HOMES WITHOUT DUCTS

There are several ways to cool a home without existing ducts. Let’s break down the most common:

1. Mini-Split Ductless Systems

Also called ductless split AC units, these systems consist of:

• One outdoor condenser

• One or more indoor air handlers

Pros:

• Easy to install compared to full ductwork

• Zoning capability (different rooms at different temperatures)

• Energy-efficient

Cons:

• Can look less seamless than traditional central AC

• Multiple units needed for full home coverage

Mini-splits are technically a form of central air without ducts, though some people prefer the term “ductless AC.” They’re a perfect fit for historic homes or small additions.

2. High-Velocity “Small Duct” Systems

High-velocity systems use small, flexible tubing to deliver conditioned air through tiny vents.

• Less invasive than traditional ducts

• Works well for retrofitting older homes

• Compatible with modern thermostats

This approach can often integrate with high-performance systems like the Goodman R32 bundle, providing a balance of DIY labor and professional support.

3. Portable or Window Units (Temporary Solutions)

• Cheap, easy to move, and non-invasive

• Good for temporary relief, supplemental cooling, or small rooms

Drawbacks:

• Won’t cool an entire home efficiently

• Can be noisy

• Often increase electricity costs

Think of these as stepping stones while you plan a permanent solution.

CHAPTER 3 — COST TO INSTALL CENTRAL HEAT AND AIR WITHOUT EXISTING DUCTWORK

Cost is often the biggest concern for homeowners asking about installing central air in a house without ducts cost. Here’s what you should expect:

These numbers vary by region, labor cost, and home size. Also note: choosing an efficient system like the Goodman 3 Ton 14.5 SEER2 R32 can save money long-term on energy bills.

CHAPTER 5 — STEP-BY-STEP OVERVIEW OF INSTALLATION OPTIONS FOR HOMES WITHOUT DUCTS

I’ve installed hundreds of systems in homes with and without ducts. Here’s a general approach:

1. Mini-Split Installation

1. Identify ideal wall or ceiling locations for indoor air handlers

2. Place the outdoor condenser on a stable, level pad

3. Run refrigerant lines and condensate piping

4. Connect electrical wiring and test

DIY-friendly aspects: mounting indoor units, routing small lines
Pro-required aspects: refrigerant handling, pressure testing

2. High-Velocity Small-Duct Installation

1. Determine optimal duct paths (ceiling, soffits, or walls)

2. Install small flex ducts and outlets

3. Connect to central condenser or air handler

4. Test airflow and balance

This approach works well with a Goodman central air bundle, even if ducts are small.

CHAPTER 6 — PERMITS, SAFETY, AND CODE CONSIDERATIONS

When installing air conditioner no duct work or central heat with no existing ductwork, you’ll likely need:

• Building permits

• HVAC permits

• Inspections for electrical and mechanical compliance

Skipping these steps may void warranties, cause insurance issues, or result in fines. Always check local regulations before starting any installation.

CHAPTER 7 — COST TO INSTALL CENTRAL HEAT WITH NO EXISTING DUCTWORK

Breaking down cost to install central heat and air without existing ductwork:

• Mini-split solution: $3,000–$10,000

• High-velocity small duct system: $6,000–$15,000

• Full ductwork system: $12,000–$25,000

• Labor and permits included in above ranges

• Energy-efficient system choice (like Goodman) may reduce operating costs by 15–20%

---

CHAPTER 8 — DIY-FRIENDLY INSTALLATION STRATEGIES

For homeowners who love to DIY, here’s what you can do safely:

• Remove old window units or portable AC

• Mount mini-split indoor units

• Install mounting pads for outdoor condenser

• Run low-voltage thermostat wiring

• Seal ductless or small ducts to maximize efficiency

What you should not DIY:

• Refrigerant charging

• Electrical connections to 240V circuit

• Pressure testing the system

By splitting labor this way, you save money, learn a lot, and still maintain warranty protection.

CHAPTER 9 — CONCLUSION: THE SMART PATH TO CENTRAL AIR WITHOUT DUCTS

If you’re considering installing central air in a house without ducts, here’s the takeaway:

1. Temporary DIY options (portable units, window units) are fine for short-term relief.

2. Mini-splits and high-velocity small-duct systems are the practical solutions for long-term comfort.

3. Goodman 3 Ton 14.5 SEER2 R32 bundle gives reliability, energy efficiency, and DIY-friendly integration.

4. Professional involvement for refrigerant and electrical work ensures safety, code compliance, and warranty coverage.
