Complete gas/electric HVAC kits — R-32 AC condenser + 80% AFUE gas furnace + evaporator coil, AHRI-certified and shipped together. Available 2–5 tons with 14.3 or 15.2 SEER2, upflow or horizontal furnace orientation. Goodman and Ace Air.
Complete HVAC kits — AC condenser + gas furnace + evaporator coil, factory-matched
A gas split system is the traditional three-piece residential HVAC setup for a home with natural gas or propane service. An outdoor AC condenser handles cooling, an indoor gas furnace handles heating, and an evaporator coil mounted on top of the furnace provides the indoor cooling interface. On this page, every listing is a pre-matched three-component kit — one order, all parts together, AHRI-certified to work as a system.
Every kit is factory-assembled, shipped from our Ocala, FL warehouse — typically out the door within 1-3 business days. We carry Goodman (a Daikin brand) and our own Ace Air Direct private label, all using R-32 refrigerant on the cooling side.
The three decisions: cooling tonnage (1 ton per 600 sq ft as a rule), heating BTU (30-60 BTU per sq ft depending on climate), and efficiency tier (14.3 or 15.2 SEER2 for cooling; all furnaces on this page are 80% AFUE). Call us at (352) 438-8992 if you'd like help picking the right combination for your home.
Five specs that matter for a gas split system kit — covering both the cooling and heating sides
Every kit on this page bundles three components — outdoor AC condenser, indoor gas furnace, and evaporator coil — tested and rated together by AHRI. This is what guarantees the advertised SEER2 and AFUE ratings in real-world operation. Buying the three pieces separately risks mismatched tonnage, incompatible coil cabinet sizes, and voided warranties.
Standard sizing rule — 1 ton of cooling per 600 sq ft of conditioned space. A 1,500 sq ft home typically needs a 2.5-ton kit. The condenser's tonnage determines the kit; the furnace is sized for heating capacity separately (BTU).
Seasonal Energy Efficiency Ratio 2 — how efficient the cooling side runs. Higher = lower summer electric bill. Southern states require 14.3 SEER2 minimum; Northern states allow 13.4. Matched systems ensure the whole kit hits the labeled rating.
Annual Fuel Utilization Efficiency measures how much of the gas burned becomes useful heat. Every kit on this page is 80% AFUE — the standard tier for most residential installs. 90%+ condensing furnaces exist but require different venting and a higher up-front cost.
Upflow furnaces sit on a basement or closet floor and blow warm air up through supply ducts overhead. Horizontal configuration lays the unit on its side for attic or crawl space installations. Kits on this page are available in both orientations — check the product title for the config that fits your install.
Cooling-side efficiency (SEER2) follows the same regional minimums as standalone AC systems
23 states spanning the upper Midwest, Northeast, and Pacific Northwest — prime gas-heat territory with cold winters and affordable natural gas. Any kit on this page is legal to install here.
27 states + DC. 13.4 SEER2 kits can't be legally installed new in these states — use the filters above to select 14.3+ SEER2 kits only. In much of the South, a heat pump split system may be a better fit than gas heat — consider both options.
Common questions about gas split system kits — components, sizing, and install
A gas split system is the traditional three-piece residential HVAC setup: an outdoor AC condenser (cooling), an indoor gas furnace (heating), and an evaporator coil that sits on top of the furnace to provide the cooling interface. It's called a 'split' system because the cooling equipment is split between indoor and outdoor units, connected by refrigerant lines. On this page, all three components come as a pre-matched kit — one order, one delivery, AHRI-certified together.
Depends on climate and fuel costs. Gas systems win in cold climates with affordable natural gas — Midwest, Northeast, Mountain West — because gas heat is cheaper to run than electric heat when it's below freezing for months. Heat pumps win in mild climates (Florida, Southeast, Southwest, coastal California) where it rarely drops below 30°F and electricity is reasonably priced. Hybrid systems (heat pump + gas furnace) are the best-of-both option in moderate-to-cold climates.
Two separate sizings. Cooling tonnage: 1 ton per 600 sq ft as a starting rule — a 1,500 sq ft home needs roughly 2.5 tons. Heating BTU: 30-60 BTU per sq ft depending on climate and insulation — a 1,500 sq ft Florida home might only need 45,000 BTU; the same home in Minnesota needs 80,000+. The kits on this page match common combinations (e.g., 2.0 ton cooling + 60K BTU heating), but for precise sizing, call us at (352) 438-8992 for a free Manual J load calculation.
You get three components: (1) outdoor AC condenser, (2) gas furnace (natural gas or propane-convertible), (3) evaporator coil matched to the condenser and sized to fit on top of the furnace. You do NOT get: refrigerant lineset (sold separately, sized to your specific install), thermostat, gas line or gas-line fittings, condensate drain plumbing, electrical whip, or ductwork. Most installers source these locally.
Most Goodman and Ace Air furnaces ship configured for natural gas and require a propane conversion kit (sold separately, typically $30-80) to run on propane. The conversion is a straightforward swap of the gas orifices and pressure regulator, done by your licensed installer during setup. Tell your installer which fuel you're using when you schedule — they'll pick up the right conversion kit.
The components age differently. The gas furnace typically lasts 15-20 years — longer than most HVAC components since there's no outdoor exposure and the burner runs fewer hours than a compressor. The AC condenser typically lasts 12-17 years, shorter in coastal installations. The evaporator coil usually outlives both and can be kept when replacing either end unit. Annual maintenance extends all three meaningfully.
Yes. We ship complete gas split system kits to all 48 contiguous states from our warehouse in Ocala, FL. Complete systems ship free — all three components on freight pallets together. Most orders leave within 1-3 business days via freight carrier with tracking and a scheduled delivery appointment. Local pickup is available in Ocala for additional savings.
