Compare systems on the same basis.
Use these matrices to choose the right project route before comparing models, contractors and financing.
Heating and cooling routes
| Decision | Central AC | Mini-split | Heat pump | Furnace | Boiler |
|---|---|---|---|---|---|
| Primary job | Cooling | Zoned heat + cool | Whole-home heat + cool | Heating | Hydronic heating |
| Distribution | Ducts | Indoor zones | Ducts or zones | Ducts | Radiators / hydronics |
| Fuel | Electric | Electric | Electric | Gas / propane / oil / electric | Gas / oil / electric |
| Key metric | SEER2 / EER2 | SEER2 / HSPF2 | SEER2 / HSPF2 | AFUE | AFUE |
| Scope risk | Ducts + electrical | Line sets + placement | Load + backup heat | Venting + airflow | Piping + venting |
| Best comparison | Installed capacity | Per-zone design | Cold-weather output | Fuel + airflow | Distribution condition |
Home-energy project routes
| Decision | Solar | Insulation | Water heater | EV charger |
|---|---|---|---|---|
| Primary outcome | Generation | Lower loads | Hot water | Vehicle charging |
| Core sizing input | Roof + usage | Assembly + climate | Household demand | Daily miles + dwell time |
| Electrical impact | Interconnection | May reduce HVAC load | May need 240V | Dedicated circuit / load management |
| Key model | Annual kWh | R-value + air leakage | UEF + first-hour rating | Delivered charging power |
| Proposal risk | Finance assumptions | Moisture / ventilation | Fuel and venting scope | Panel and wiring scope |

19 comparisons
Heat pump vs. Furnace
Compare fuel, climate performance, cooling, electrical scope and 10-year ownership before replacing a heating system.
Central AC vs. Heat pump
Both can cool through ducts; the key difference is whether the outdoor system also supplies heat.
Mini-split vs. Central AC
Compare zoning, ducts, indoor-unit placement, electrical work and whole-home distribution.
Boiler vs. Furnace
Hydronic and forced-air heat differ in distribution, response, cooling integration and replacement scope.
Storage tank vs. Tankless
Compare peak hot-water demand, fuel and venting, installation changes, maintenance and delivered capacity.
Heat-pump water heater vs. Gas water heater
Compare room conditions, electrical and venting work, recovery, operating cost and installation constraints.
Solar-only vs. Solar + battery
Separate energy-production economics from backup-power and time-shifting goals.
Level 1 vs. Level 2
Start with daily miles and overnight dwell time before paying for maximum charging power.
Repair vs. Replace
Compare system age, repair cost, reliability, comfort problems and remaining ownership cost before approving major HVAC work.
Ducted heat pump vs. Ductless heat pump
Compare distribution, zoning, indoor-unit placement, duct losses and installation scope for whole-home electrification.
Cash or ownership loan vs. Lease or power purchase agreement
Separate system performance from financing terms, ownership rights, tax treatment, transfer rules and total payments.
Home battery vs. Standby generator
Compare outage duration, supported loads, fuel, maintenance, solar integration and operating constraints before buying backup power.
Ducted heat pump vs. Ductless mini-split
Compare whole-home distribution, zoning, ducts, indoor-unit placement and cold-weather performance before selecting a heat-pump route.
Heat pump vs. Boiler
Compare electrified heating and cooling with hydronic replacement by distribution, backup needs, site work and full ownership cost.
Heat pump vs. Electric baseboard
Compare a heat pump with resistance baseboard heat by distribution, comfort, electrical work and seasonal energy use assumptions.
Central AC vs. Window air conditioner
Compare whole-home cooling with room cooling by distribution, installation, noise, electrical use and ownership scope.
Mini-split vs. Window air conditioner
Compare permanent ductless room conditioning with temporary window cooling by comfort, heating, installation and ownership path.
Single-stage AC vs. Variable-speed AC
Compare compressor control, comfort, sound, matched-system requirements and installed scope instead of treating a feature label as a guarantee.
Ducted mini-split vs. Ductless mini-split
Compare concealed ducted zones with wall, floor or ceiling ductless units by room layout, access, zoning and serviceability.
Compare brands through real proposal evidence.
No invented failure rates or universal winner. Start with official product information, then normalize exact models, installation, warranty and financing.
