How much is a combined heating and cooling system?
A combined heating and cooling system (like a Goodman packaged gas unit such as model PGB024075-1) typically costs about $10,000 to $20,000 installed for many homes, with total price driven mostly by equipment size, ductwork condition, and installation complexity.
Installed HVAC pricing is a bundle of equipment plus labor plus materials. The biggest cost factors usually include:
- System type and efficiency (packaged gas vs split system; higher efficiency costs more)
- Capacity and sizing (tonnage and BTU output matched to the home)
- Ductwork condition (repairs, sealing, resizing, or replacement)
- Electrical and gas line work (disconnects, whip, shutoff, sediment trap, venting)
- Permits and code-required upgrades (varies by location)
- Accessibility (roof curb, tight mechanical spaces, crane needs)
These ranges help set expectations for a packaged heating and cooling replacement.
| Scenario | Typical installed range | What it usually includes |
|---|---|---|
| Like-for-like packaged unit swap | $10,000 to $15,000 | Basic removal and replacement, minor materials |
| Replacement plus moderate duct or curb work | $13,000 to $18,000 | Duct repairs, curb/adaptor, added labor |
| Complex install or major upgrades | $16,000 to $20,000+ | Significant ductwork, electrical/gas changes, access challenges |
When a packaged unit is not heating or cooling, replacing a failed component can be far less expensive than replacing the entire system. For example, common repair-related parts for PGB024075-1 include the furnace inducer vent motor assembly B2959000S or the central air conditioner condenser fan motor B13400251S.
A correct diagnosis can prevent unnecessary replacement. If the issue is a single failed motor, capacitor, limit switch, or burner component, a targeted repair often restores safe operation at a fraction of full system cost.
We recommend these steps before committing to a full change-out:
- Confirm the exact model number on the unit data plate
- Identify whether the problem is cooling-only, heating-only, or airflow-related
- Check for obvious airflow restrictions (dirty filter, blocked returns, closed registers)
- Compare repair options using the parts list for PGB024075-1, then search broader inventory on Sears PartsDirect

What's the average lifespan of a Goodman furnace?
A Goodman gas furnace in a packaged unit like model PGB024075-1 typically lasts 15 to 20 years. Regular maintenance (clean airflow, correct gas combustion, and healthy motors and controls) is what most directly determines whether you land closer to 15 years or push past 20.
Most homeowners see these timeframes when the system is installed correctly and serviced regularly:
- Gas furnace heat section: 15 to 20 years
- Blower motor and inducer components: often 8 to 15 years
- Electrical controls (transformer, switches): often 10 to 20 years
- Outdoor fan motor and capacitor-related parts: often 7 to 15 years
These are the most common factors that change lifespan on a Goodman packaged gas unit:
- Dirty filters or restricted return air (overheats the heat exchanger and stresses the blower)
- Blocked flue or venting issues (stresses the inducer and safety controls)
- Overheating trips from poor airflow (can involve a limit switch)
- Frequent short cycling (extra wear on ignition and motors)
- Coastal corrosion or water intrusion (accelerates cabinet and component damage)
If your unit is aging, these parts are often involved in “no heat,” “no cool,” or shutdown symptoms:
| Symptom | Common area | Example part on this model |
|---|---|---|
| Heat shuts off, then restarts | Overheat protection | Limit switch, 180-degree 1370901S |
| Draft/vent problems, pressure switch errors | Inducer system | Furnace inducer vent motor assembly B2959000S |
| Weak airflow or noisy air handler | Blower assembly | Central air conditioner air handler blower motor B13400313S |
Knowing the expected 15 to 20 year lifespan helps you decide whether to repair or plan ahead. On an older PGB024075-1, replacing a failed motor or safety switch can restore reliable operation, but repeated failures often signal broader wear from heat, vibration, or airflow restriction.
We recommend matching parts by your exact model number (PGB024075-1) and the symptom you are seeing. You can order parts from the parts list for this model, or search by model number on Sears PartsDirect.

What are the common problems with Goodman AC units?
Common problems we see on Goodman package gas units like model PGB024075-1 include no cooling, weak airflow, outdoor fan issues, nuisance shutdowns in heat mode, and electrical failures. Many are caused by airflow restrictions, dirty coils, or failing motors and capacitors.
- Not cooling or short cycling: dirty condenser coil, low airflow, failing run capacitor, or a condenser fan problem.
- Weak airflow indoors: clogged filter, blocked return/supply vents, or a failing blower motor/wheel.
- Outdoor fan not running: bad fan motor, bad capacitor, or wiring/connection issues.
- Heat shuts off quickly: limit switch opening from overheating (often airflow related).
- No heat or rough ignition: inducer/venting problems, burner issues, or restricted airflow.
If your symptoms match, these are common replacement candidates for the Goodman PGB024075-1:
- Central air conditioner condenser fan motor B13400251S (fan not running, overheating, loud motor)
- Overload CAP050300440RSP (hard starts, intermittent compressor operation)
- Central air conditioner air handler blower motor B13400313S (weak airflow, motor hums, no indoor air)
- Central air conditioner limit switch, 180-degree 1370901S (heat trips off, unit overheats)
- Furnace inducer vent motor assembly B2959000S (no heat, pressure/venting related shutdowns)
- Set thermostat to COOL, lower setpoint 3 to 5 degrees; confirm the unit starts and stays running.
- Replace/clean the air filter; confirm all supply and return vents are open.
- Inspect the outdoor coil for dirt and debris; gently clean the fins.
- Listen for motor hum (fan or blower) without rotation; that often points to a capacitor or motor issue.
- Check for a tripped breaker or blown disconnect fuses (reset once; repeated trips indicate a fault).
| Symptom | Most likely area | Common part on this page |
|---|---|---|
| Outdoor fan not spinning | Condenser section | Condenser fan motor |
| Weak airflow inside | Air handler section | Blower motor or blower wheel |
| Heat stops, then restarts | Safety/overheat | Limit switch |
| No heat, inducer won’t run | Draft/venting | Inducer vent motor assembly |
Airflow and electrical issues can cascade: a dirty filter or weak blower can overheat the heat section and trip the limit switch, and a failing condenser fan can drive head pressure up and stress the compressor. Fixing the root cause prevents repeat failures.
For ordering, you can buy replacement parts from the parts list for model PGB024075-1, or search by model on Sears PartsDirect.
