Can you have both a heat pump and a furnace?
Yes. You can have both in a dual-fuel setup: a heat pump handles mild-weather heating and cooling, and a gas furnace takes over when it is too cold for the heat pump to heat efficiently. For Icp model PGF024K060A, confirm the exact heating configuration and controls in the owner's manual.
A dual-fuel system uses two heat sources and switches between them automatically based on outdoor temperature and thermostat settings.
- Heat pump provides efficient heat in moderate temperatures
- Gas furnace provides stronger heat output in colder temperatures
- A thermostat or control board manages the changeover point
- You typically get lower operating cost than running gas heat all season
- Comfort is more consistent during cold snaps
Dual fuel can be built either way; the key is that you have a heat pump plus a gas furnace section.
| Setup type | Where the equipment sits | What it usually includes |
|---|---|---|
| Packaged dual fuel | Outdoors in one cabinet | Heat pump section plus gas heat section |
| Split dual fuel | Indoor plus outdoor units | Outdoor heat pump plus indoor gas furnace |
Use the model documentation and the unit data plate to verify what you actually have installed and how it is controlled.
- Thermostat type (single-stage, multi-stage, dual-fuel capable)
- Presence of gas components (gas valve, burners, ignition system)
- Outdoor temperature sensor (if used for changeover)
- Control wiring and safety switches
- Service history (recent board, igniter, or inducer replacements)
Dual fuel prevents high electric run time in very cold weather while still letting you take advantage of heat pump efficiency when conditions are mild. Correct changeover setup also reduces short cycling and protects major components.

How many square feet will a 2-ton heat pump cool?
A 2-ton (24,000 BTU) heat pump typically cools about 900 to 1,200 sq ft in an average, well-insulated home. For an Icp PGF024K060A packaged unit, the real coverage depends on your climate, insulation, duct sizing, and airflow settings; use the sizing guidance in the owner's manual.
A square-foot estimate is only a starting point. These factors commonly push the “right” size up or down:
- Climate zone (hotter, more humid areas usually need more capacity)
- Insulation and air sealing (older, leaky homes need more)
- Window area and sun exposure (large west-facing glass increases load)
- Ceiling height (tall ceilings increase conditioned volume)
- Ductwork design and airflow (undersized ducts reduce delivered cooling)
Your Icp packaged unit manual lists typical air delivery for “up thru 2 tons” at about 800 to 900 CFM, and it also notes duct velocity guidance (about 1000 fpm in trunk ducts and 800 fpm in branches). If airflow is low because of duct restrictions or a dirty filter, the unit can feel “undersized” even when the tonnage is correct.
| Item | Typical target for 2-ton | Why it matters |
|---|---|---|
| Cooling airflow | 800 to 900 CFM | Low airflow reduces comfort and capacity |
| Trunk duct velocity | Up to 1000 fpm | Helps prevent noise and restriction issues |
| Branch duct velocity | Up to 800 fpm | Supports balanced room airflow |
Oversizing can cause short cycling and poor humidity control; undersizing can run constantly and still miss the thermostat setpoint. Getting airflow and duct sizing right protects key components like the compressor, motors, and limit controls.
- Confirm the unit is actually operating as a 2-ton configuration (nameplate and setup)
- Check filter condition and return-air restrictions
- Verify supply registers are open and not blocked
- Compare duct sizing and airflow guidance in the owner's manual
- If comfort is uneven, inspect for duct leaks, crushed flex duct, or closed dampers

What is the most common part to fail on an AC unit?
On an AC system, the most common failure we see is a run capacitor (it helps the compressor and fan motor start and stay running). On your Icp PGF024K060A package unit, a dirty air filter is also a top cause of poor cooling and can contribute to compressor failure, so monthly filter checks matter. See the maintenance schedule in the owner's manual.
- Run capacitor: AC hums, outdoor fan will not start, hard starting, short cycling.
- Contactor/relay: Outdoor unit will not come on, chattering, intermittent cooling.
- Fan motor: Outdoor fan slow, noisy, or not spinning; unit overheats and shuts down.
- Dirty air filter: Weak airflow, icing, poor cooling; can stress the compressor.
- Safety limits: Unit may run fans until a limit resets after overheating.
Turn power off at the disconnect/service panel before opening panels.
- Replace or clean the air filter monthly; install with airflow arrows pointing the right direction.
- Clear debris around the condenser; keep shrubs at least 30 inches away.
- Check that the thermostat is calling for cooling and the indoor blower is moving air.
- Look for obvious wiring damage or loose spade connectors.
- If the outdoor fan is not running, stop the system and inspect the fan motor and capacitor circuit.
| Symptom | Common suspect | Example part on this model |
|---|---|---|
| Outdoor unit will not start | Contactor | Contactor (listed for this model) |
| Outdoor fan not spinning | Fan motor | Fan motor 1086598 |
| Burners/heat side safety trip (package unit) | Limit control | Limit switch 1013102 |
| Blower timing/control issues | Control board | Furnace fan control board 1084197 |
A failed capacitor or contactor can stop cooling immediately, but restricted airflow from a dirty filter can quietly reduce performance and raise compressor stress over time. Following the monthly and seasonal checks in the manual helps prevent expensive breakdowns.
