What AC Installation Actually Covers
New air conditioner or full-system replacement? HVACZILLA connects you with local AC installation pros for right-sized systems, proper airflow, and clean refrigerant-line work — central air, mini-splits, and heat pumps.
Right-Sized Systems
Proper Manual-J sizing, matched indoor/outdoor equipment, and refrigerant-line sets that won't haunt you in year three.
Central, Mini-Split, Heat Pump
Whatever fits your home and climate — not just what the installer has on the truck. Compare efficiency, cost, and rebates.
Clean Install Work
Proper airflow, condensate drainage, electrical, and commissioning so the system actually performs at its rated efficiency.
AC Installation Options — and Which Is Right for Your Home
The right system depends on your home, climate, and how long you plan to stay. These are the real options an installer should walk you through, not just the one they want to sell.
Central split-system AC
The standard for most U.S. homes with existing ductwork. Outdoor condenser, indoor coil on top of the furnace, refrigerant lineset between them. Efficient, quiet, widely serviceable.
Heat pump
A single system that cools in summer and heats in winter. Federal tax credits make this cost-competitive with central AC + furnace combos. Right answer in most moderate climates.
Dual-fuel hybrid
Heat pump for mild weather, gas furnace as backup below 30°F or so. Best of both in cold-winter areas. More moving parts, more complexity, excellent efficiency in the right climate.
Ductless mini-split
Wall-mounted or ceiling-cassette indoor units, each with its own thermostat. Perfect for additions, retrofits without ducts, and zoned comfort. Premium efficiency.
Multi-zone ductless
One outdoor unit, 2–8 indoor heads. Run only the zones in use. Per-zone comfort without central ductwork. Great for old homes, additions, and home offices.
Package unit
All-in-one outdoor or rooftop. Common in the Southwest and on flat-roof commercial-style buildings. Simpler service access, slightly less efficient than split systems.
Geothermal
Ground-source heat pump. Massive efficiency, massive upfront cost, long payback. Qualifies for federal 30% tax credit. Right call in some homes, wrong call in most.
Variable-refrigerant-flow
Commercial-grade multi-zone systems. Excellent for larger homes with complex zoning needs. Requires a specialist installer.
High-velocity / space-saving
Small-diameter ducting for historic homes where full-size ductwork won’t fit. Unsere/Spacepak systems. Niche but real solution.
SEER2, HSPF2, and What Efficiency Tier to Actually Buy
Federal minimums changed in 2023 with the SEER2 / HSPF2 standard. Here’s the tier map that actually makes sense for most homes.
SEER2 15 (federal minimum)
The floor. New installs can’t go below this. If cost is the dominant factor and you won’t stay long, this is defensible.
SEER2 16–17 (value sweet spot)
10–15% more efficient than the floor, modestly more expensive, usually pays back within 4–7 years in most climates.
SEER2 18+ (premium)
Two-stage and variable-speed equipment. Pays back in high-usage climates and for long tenure. Better comfort, better dehumidification, quieter.
SEER2 20+ (top-of-line)
Variable-speed inverter systems. Expensive. Worth it for specific cases (high utility rates, long tenure, comfort priority) but not a default.
HSPF2 7.5 (federal minimum heat pump)
Lower bound on heating-side efficiency. For cold climates, look higher.
HSPF2 9–10+ (cold-climate heat pump)
Cold-climate inverter heat pumps from Mitsubishi, Fujitsu, Carrier Infinity, Trane XV. Work at 5°F and below. Required reading if you’re in a cold zone.

How long does an AC installation take?
A straightforward AC replacement (same location, compatible equipment) takes 1 day. Full new installs with duct modifications or electrical upgrades take 2-3 days.
How much does a new AC system cost?
Central AC replacement typically runs $5,500-$12,000 installed, depending on size (tonnage), efficiency (SEER2), and equipment tier. Heat pumps and mini-splits vary. Ask for multiple quotes.
What SEER or SEER2 rating should I pick?
SEER2 15 is the new federal minimum (2023+). SEER2 16-17 is the value sweet-spot. SEER2 18+ is for high-usage climates or longer payback tolerance. Don't overspend on efficiency you won't recover.
Central AC vs mini-split vs heat pump — which is best?
Central AC for homes with existing ductwork. Mini-splits for additions, retrofits, or zoned comfort. Heat pumps for moderate climates or all-electric homes — now often the right choice.
Are there rebates or tax credits for new AC?
Yes. Federal IRA tax credits cover up to 30% on qualifying heat pumps. Many utilities offer local rebates. Your installer should know the current programs or check energystar.gov.
