How Much Does AC or Furnace Installation Cost? Key Factors Explained

When your home or business feels more like a sauna or an icebox, getting a new AC or furnace isn’t just a comfort upgrade—it’s a necessity. But as soon as you start searching for “AC Repair near you” or “emergency hvac installation,” the big question hits: How much will this really cost?

At Briggs Heating, we know the process can feel overwhelming. Prices vary. Quotes can be confusing. We’re here to break down the real numbers, share what impacts your final bill, and offer practical tips to help you plan—without hidden surprises.

Average Price Ranges

Before you dive into details, it helps to know the ballpark. AC and furnace installation costs are a bit like buying a car—price depends on what you choose, how big it needs to be, and what features you want.

• Residential AC Installation: $4,500–$12,000+
• Residential Furnace Installation: $3,500–$8,500+
• Commercial HVAC Install: $7,000–$30,000+ (depends on building size and complexity)

That range is wide for a reason. A small cottage and a 10,000-square-foot office simply aren’t in the same league. Your price is shaped by more than just the unit itself.

Sample Quotes from Briggs Heating

• Homeowner in a 2,000 sq. ft. house: New 16 SEER central AC, ductwork review, mid-tier brand: $7,800

“Briggs gave us a clear quote, no games. The crew finished fast and cleaned up after themselves. Our new system runs better than ever.”
— J. Martinez, homeowner

What Affects the Cost? 🛠️

Not all installs are created equal. Here’s what really drives your investment:

1. System Size & Capacity

Think of it like buying shoes—too small, and you’ll be uncomfortable; too big, and you’re wasting money. Your HVAC system must fit your space. Sizing is based on square footage, insulation, and even window count.

• Larger spaces need bigger, more powerful equipment.
• Undersized units work overtime and wear out early.
• Oversized systems short-cycle and waste energy.

2. Efficiency Ratings: SEER & AFUE

A system’s SEER (Seasonal Energy Efficiency Ratio) or AFUE (Annual Fuel Utilization Efficiency) rating is like its miles per gallon. Higher numbers mean lower energy bills—but higher upfront cost.

• SEER 14 vs. SEER 18: Higher SEER costs more to install, but saves money over time.
• AFUE 80% vs. 96%: High-efficiency furnaces are pricier but can cut heating bills by 20%+.

3. Ductwork & Airflow

If your ducts are leaky, dirty, or poorly sized, your new unit can’t do its job. Sometimes, a simple cleaning is enough. Other times, repairs or a full replacement are needed.

• Duct repairs: $500–$2,500+
• Full duct replacement: $3,000–$6,000+

4. Brand & Features

Just like cars, HVAC brands and models vary. Standard brands are reliable, but premium models come with perks like smart thermostats, variable speed motors, or advanced air filtration.

5. Labor & Installation Complexity

Labor includes everything from removing your old unit to safely connecting gas lines or refrigerant. Tight crawlspaces, steep roofs, or unique building layouts can increase labor time.

6. Permits & Code Requirements

Permits add to upfront cost, but they ensure your install is safe and legal. HVAC work must follow local codes, including the International Mechanical Code (IMC) and manufacturer instructions.

7. Location & Regional Differences

Labor rates, climate, and utility rebates all affect final pricing. Hotter climates may need higher-capacity units or extra cooling features.

Ways to Save on Installation 💡

Getting the right system shouldn’t break the bank. Here’s how you can keep costs in check:

1. Look for Rebates & Incentives

• Utility companies often offer cash-back for high-efficiency systems.
• Federal programs sometimes provide tax credits for energy upgrades (reference: ENERGY STAR).

2. Financing Options

Upgrading your HVAC system is an investment. Briggs Heating offers flexible financing plans to spread costs over time, subject to approval.

• Fixed monthly payments
• No early payoff penalties

3. Maintain Your System

Regular maintenance extends your system’s life. Change filters, schedule professional checkups, and protect your investment from breakdowns.

4. Compare Features vs. Needs

Do you need the latest tech, or is a basic model just fine? Sometimes, mid-tier systems hit the sweet spot between price and performance.

5. Plan Ahead

If possible, replace aging systems before they fail in the middle of a heatwave or deep freeze. Emergency installs can cost more due to after-hours labor.

Residential vs. Commercial Installs

Residential

• Usually a single system, sized for your home.
• Installation takes 1–2 days.
• Focus on comfort, quiet, and indoor air quality.

Commercial

• Larger, more complex systems (rooftop units, split systems, zoning).
• Can involve multiple units and custom controls.
• May require coordination with building management or city inspectors.
• More extensive permitting and safety checks.

How to Avoid Unpleasant Surprises

• Always ask for licensing and insurance.
• Review the full scope of work before signing.
• Check references or testimonials.

Frequently Asked Questions

How long does installation take?

• Most residential jobs: 1–2 days.
• Commercial jobs: 2–5 days, depending on complexity.

Do I need to replace my ductwork?

Not always. We inspect your ducts and only recommend replacement if they’re leaky, damaged, or too small for your new system.

Are high-efficiency systems worth it?

For many homes and businesses, yes—especially if you plan to stay put for a while. The savings on utility bills can add up over time.

What’s the difference between emergency hvac installation and regular installs?

Emergency hvac service means we work outside normal hours, often the same day. It’s more expensive due to overtime, but sometimes comfort can’t wait.

Local & Seasonal Factors to Consider 🌦️

• Heating-dominated climates: Heavier focus on furnace size and efficiency.
• Cooling-dominated regions: Higher SEER AC units may be required by code.
• Allergy season: Consider air scrubbers or IAQ (indoor air quality) add-ons.
• Storm season: Backup generator installations can keep your HVAC running when the grid goes down.

Always check local building codes and consult resources like the International Energy Conservation Code (IECC) for guidance.

A new AC or furnace is a big decision. The right team makes all the difference—not just on installation day, but for years to come. Briggs Heating is here 24/7 for emergencies, honest advice, and quality work.
