Installation guide
How much does it cost for a whole house air conditioner?
A whole-house (central) air conditioner typically costs $6,000 to $20,000 installed, with many homeowners landing around the middle of that range. Your final price depends on tonnage (capacity), efficiency (SEER2), whether ductwork needs repair or replacement, and local labor rates.
What drives the installed price
- System size (tons/BTUs): Larger homes need higher capacity equipment.
- Efficiency rating (SEER2): Higher efficiency costs more up front but lowers operating cost.
- Ductwork condition: Leaky, undersized, or damaged ducts add significant labor and materials.
- Electrical and controls: New disconnect, whip, breaker upgrades, or thermostat wiring can add cost.
- Installation complexity: Rooftop vs. ground pad, line-set routing, and access all affect labor.
Typical cost ranges (installed)
| Scenario | What’s included | Typical range |
|---|---|---|
| Straight swap | Replace outdoor condenser and connect to existing ductwork/line set (when compatible) | $6,000 to $12,000 |
| Mid-level upgrade | Higher efficiency equipment plus minor electrical or refrigerant line work | $10,000 to $16,000 |
| Major project | New or extensive ductwork, significant electrical upgrades, difficult access | $15,000 to $20,000+ |
How this relates to your Coleman model BPCH0361BA
If you are replacing a Coleman Evcon central air conditioner like BPCH0361BA, the biggest cost swing is usually whether the existing ductwork and refrigerant line set can be reused and whether the indoor coil and outdoor unit are being replaced as a matched system.
Why it matters
Correct sizing and a quality install protect the compressor, improve humidity control, and reduce short cycling. Accessories like a compressor start kit are sometimes used to improve starting under low voltage or high load conditions; installation is intended for qualified technicians per the installation guide.

Is a temperature of 36.1 ok?
Yes, 36.1°F is an excellent air temperature for a Coleman Evcon central air conditioner model BPCH0361BA. Most central AC systems deliver supply air in the mid-50s°F, so a 36.1°F reading usually indicates you are measuring the wrong location or the wrong unit (°C vs °F), or you are reading coil temperature, not room air.
What “36.1” usually means (and what to do)
- If it is 36.1°F at a supply vent: recheck; that is colder than normal supply air.
- If it is 36.1°F on the copper line or near the indoor coil: that can be normal during operation.
- If it is 36.1°C: that is about 97°F; you are likely reading the wrong mode or device.
- If it is 36.1°F room temperature: the thermostat or sensor is not reading correctly.
- If cooling performance is poor: check airflow first (filter, registers, blower).
Normal temperature targets for central AC
| What you measure | Typical range | What it tells you |
|---|---|---|
| Indoor room temperature | 68 to 78°F | Comfort setting, thermostat control |
| Supply air at a vent | 50 to 60°F | Normal cooling output in many homes |
| Return-to-supply “temperature drop” | 16 to 22°F | Quick health check for airflow and charge |
Quick checks we recommend
- Measure return air and supply air with the same thermometer after 10 to 15 minutes of run time.
- Confirm your thermometer is set to °F, not °C.
- Make sure the air filter is clean and all supply registers are open.
- If the outdoor unit short-cycles or struggles to start, follow the electrical and start-kit guidance in the installation guide.
Why it matters
A 36.1°F reading can be perfectly fine or a red flag depending on where you measured. Correct measurement points help you avoid misdiagnosing issues like low airflow, icing, or control problems.

Who makes BPCH0361BA air conditioners?
Coleman makes the BPCH0361BA central air conditioner as part of the Coleman Evcon product line. In the installation documentation for model BPCH0361BA, the equipment is identified under the Unitary Products Group family, and the compressor listed for this model is a Bristol unit.
What the installation guide tells us for BPCH0361BA
In the installation guide, BPCH0361BA appears in a start kit application table and is shown with a Bristol compressor (listed as H23A323ABCA). This helps confirm the equipment family and key component sourcing.
Key identifiers you can match on the unit data plate:
- Brand: Coleman
- Model number: BPCH0361BA
- Product type: Evcon central air conditioner (outdoor condensing unit)
- Compressor brand shown in guide: Bristol
Why “who makes it” can mean two different things
For central air conditioners, customers often mean either the equipment brand or the component manufacturer.
| What you mean by “makes it” | What to look for | BPCH0361BA example |
|---|---|---|
| Equipment brand/manufacturer | Nameplate brand and model | Coleman BPCH0361BA |
| Major component supplier | Compressor label, capacitor, contactor | Bristol compressor listed in guide |
Why it matters when ordering parts
Matching the correct maker and model prevents wrong-part returns and wiring mismatches, especially for electrical items like a start kit, start relay, start capacitor, dual run capacitor, and contactor.
Before you choose parts, we recommend:
- Confirm the full model number on the outdoor unit rating plate (BPCH0361BA)
- Compare the compressor label to the guide listing (Bristol)
- Use the wiring diagram on the control box cover when replacing electrical parts
- Shut off power at the disconnect and breaker before opening the control box
