Heat Pump System:
Heats and cools your home using electricity and outdoor air. More energy-efficient, lower operating costs, environmentally friendly, and works well in moderate to warm climates. Qualifies for rebates and tax credits.

Gas System:
Uses natural gas for heating and requires a separate air conditioner for cooling. Better for extreme cold climates where heat pumps are less efficient. Higher fuel costs but may have lower upfront equipment expenses.

Best choice depends on: Your climate (heat pumps excel in Georgia), budget for upfront costs, long-term energy savings goals, and environmental priorities. Heat pumps typically save more money over time through lower utility bills. Contact our team for a personalized recommendation based on your home and location.

The best way to ensure you've chosen the right system is to match it with your home's cooling and heating needs. Consider your home's square footage, climate, insulation, and the number of zones you want to control. You can look at the sizing guide here, and our support team can help you narrow down options based on your specific situation. If you're unsure, we recommend consulting with a professional HVAC technician who can perform a detailed load calculation for your home.

Split System: Features separate indoor and outdoor units ideal for homes with basements or crawlspaces. Offers higher SEER ratings, better efficiency, and more customization for placement.

Packaged System: Contains all components in one outdoor unit, perfect for smaller homes or limited indoor space. Easier to install with lower maintenance needs.

Quick decision: Have indoor space? Choose split for superior efficiency. Limited space? Choose packaged.

HVAC sizing is measured in tons, where one ton equals 12,000 BTUs of cooling capacity. While you can estimate using square footage (roughly 600 square feet per ton for residential homes), the most accurate method is a professionalManual J load calculationthat considers your home's insulation, orientation, windows, climate, and occupancy patterns.

Tonnage => BTU/Hour
1 ton => 12,000 BTU
1.5 ton => 18,000 BTU
2 ton => 24,000 BTU
2.5 ton => 30,000 BTU
3 ton => 36,000 BTU
3.5 ton => 42,000 BTU
4 ton => 48,000 BTU
5 ton => 60,000 BTU

Home Size (Sq. Ft.) => Recommended Tonnage
750–1,000 => 2 tons
1,050–1,400 => 2.5 tons
1,450–1,700 => 3 tons
1,750–1,900 => 3.5 tons
1,950–2,200 => 4 tons
2,250+ => 5 tons

Important: Undersizing leads to inadequate cooling; oversizing wastes energy and money. When in doubt, consult a professional. Reach out to us at sales@acunitsforless.com or via Live Chat.

If you're planning multiple units (for a ductless mini-split system or zoned setup), calculate the cooling needs for each zone or room separately using the same Manual J methodology. Add the tonnage requirements for each area to determine your total system capacity. For example, if your master bedroom is 800 sq. ft. (requiring 1.5 tons) and your living room is 1,200 sq. ft. (requiring 2 tons), you'd want a 3.5-ton system or a multi-zone setup with smaller indoor units. Our team can help you design a custom multi-zone layout based on your home's layout and needs.

Currently due to regulations, we are only selling and shipping Trane Residential units in the state of Georgia.

SEER stands for Seasonal Energy Efficiency Ratio-it measures how efficiently an air conditioning or heat pump system operates over an entire cooling season.

SEER2 stands for Seasonal Energy Efficiency Ratio 2-it's the updated, more accurate standard introduced in 2023. SEER2 provides a more realistic assessment of real-world performance by testing at various load levels and temperature conditions.

The key difference is how the systems are tested.

SEER testing used fixed temperature conditions and didn't fully account for the external static pressure in typical duct systems.

SEER2 testing is more comprehensive-it accounts for varying temperatures (65°F to 104°F), includes partial-load efficiency testing to mimic real-world fluctuating demands, and uses proper duct system static pressure to prioritize furnace blower efficiency.

Important to know:SEER2 ratings are typically 4–7% lower than SEER ratings for the same system because the testing is stricter and more realistic. For example, a 16 SEER system might have a SEER2 rating of around 14. Don't compare old SEER numbers directly to new SEER2 ratings-they use different standards.

Yes! The Home Energy Improvement Program through Georgia Power offers incentives for qualified customers in the state of Georgia purchasing high-efficiency HVAC systems like ductless mini-split heat pumps or heat pump water heaters. Our salesperson share incentive details at purchase to help you save on premium equipment. Additional rebates may be available through your local utility company or federal programs-visit Energy.gov to check your area. Ask our team for your AHRI certificate to submit rebate applications.

Note:To qualify, you must be a Georgia Power customer.

You can find the AHRI certificate on the AHRI website here.

For split systems, your indoor unit must be properly matched with your outdoor unit (condenser) to achieve the rated efficiency and ensure system longevity. You can always visit the AHRI website and use their AHRI Matchup tool to find a compatible system. The best way to find help is to reach out to us via Live Chat or email sales@acunitsforless.com.

R-32 is a single-component, low-GWP refrigerant used in modern HVAC systems as an eco-friendly alternative to R-410A. It has a Global Warming Potential of 675-one-third lower than R-410A (GWP 2,088)-and offers zero ozone depletion potential. R-32 delivers approximately 10% better energy efficiency and improved heat transfer, requires 30% less refrigerant charge, and has been safely used in over 160 million units worldwide since 2012. It's classified as A2L (mildly flammable) and represents the next generation of environmentally sustainable cooling technology.

R-454B is the next-generation, environmentally friendly refrigerant with the lowest Global Warming Potential (GWP of 466) compared to R-32 and R-410A. It maintains high efficiency, meets current EPA regulations, and ensures your system remains compliant for years to come. Choosing R-454B means investing in future-proof technology that's better for the environment and your wallet.

Effective January 1, 2025, the EPA enacted a regulation prohibiting manufacturers from producing or importing new HVAC systems using R-410A. This is because R-410A has a very high Global Warming Potential (GWP) of 2,088-meaning it contributes significantly to climate change if released into the atmosphere.
