Who makes Evcon air conditioners?
Evcon air conditioners are made under the Coleman family of HVAC brands; Evcon equipment is commonly associated with the York/Unitary Products Group (UPG) brand family. For your Coleman Evcon model ERCQ0361BBA, that means the Evcon name is part of a larger HVAC manufacturing lineup.
What that means for parts and service
When you’re identifying parts for an Evcon central air conditioner, the most important detail is the model number and the data plate information, not just the Evcon name.
- Use the full model number ERCQ0361BBA when searching parts diagrams and lists
- Match electrical parts by ratings (voltage, capacitance, amperage), not by appearance alone
- Match refrigeration-side parts by exact application (metering device type, tonnage, refrigerant)
- Keep wiring colors and terminal labels consistent when replacing controls
- If you’re unsure, document the old part’s markings before removing it
Where to find the model and ID information
Most central air conditioner outdoor units list the model and serial information on a rating plate on the cabinet. If the label is faded, take a clear photo and compare characters carefully.

Quick brand-family overview
| Name you see | What it usually indicates | Why it matters |
|---|---|---|
| Evcon | A brand name used on HVAC equipment | Helps identify the product line |
| Coleman | The brand shown on this model page | Useful for cross-referencing |
| York/UPG family | The broader manufacturing/brand group | Helps explain shared parts and designs |
Why it matters
Evcon branding can appear across different production eras and product lines. Using the exact model number ERCQ0361BBA prevents ordering the wrong capacitor, contactor, fan motor, or control component.

What is the most common AC repair?
The most common central AC repair on systems like the Coleman ERCQ0361BBA is replacing a failed run capacitor (often paired with a contactor issue). Capacitors wear out from heat and electrical stress and can cause hard starting, humming, or a condenser fan or compressor that will not run.
Most common repairs we see (and what you notice)
- Run capacitor: outdoor unit hums, starts then stops, or fan will not spin without a push.
- Contactor: outdoor unit will not turn on, chattering, or intermittent cooling.
- Dirty air filter or restricted airflow: weak airflow, icing on the indoor coil, poor cooling.
- Clogged condensate drain: water around the indoor unit, safety switch trips (if equipped).
- Loose/burned wiring or blown fuse/breaker: system dead, repeated trips, burning smell.
Quick checks you can do safely
Turn power off at the thermostat and breakers before inspecting anything.
- Confirm the thermostat is set to COOL and the temperature is set lower than room temp.
- Check and replace the return air filter; most homes need it changed every 1 to 3 months.
- Clear leaves and debris from the outdoor condenser; keep about 2 feet of clearance.
- Look for a tripped breaker; if it trips again, stop and diagnose the cause.
- If you suspect an electrical issue, use our guides: how to tell if a fuse is blown and how to use a multimeter to test electrical parts video.
Repair difficulty and when to stop
| Issue | Typical DIY? | Why it matters |
|---|---|---|
| Filter/airflow restriction | Yes | Prevents coil icing and compressor strain |
| Condensate drain clog | Sometimes | Prevents water damage and shutdowns |
| Capacitor/contactor | Sometimes | High voltage; wrong wiring can damage motors |
| Refrigerant leak | No | Requires EPA-certified handling and proper charging |
| Compressor failure | No | Major electrical and sealed-system work |
Why this matters
Catching the common failures early (especially airflow problems and weak electrical components like capacitors) prevents repeat shutdowns, overheating, and expensive compressor damage on a central air conditioner.

What is the most expensive part to replace on an AC unit?
On a central AC like the Coleman ERCQ0361BBA, the most expensive single component to replace is typically the compressor. It is the “heart” of the outdoor unit, and when it fails, the repair often involves major labor plus refrigerant handling.
Most expensive AC parts (typical)
Costs vary by region, refrigerant type, and accessibility, but these are the parts that most often drive the highest repair totals:
- Compressor: usually the top-cost repair because it is sealed-system work
- Condenser coil (outdoor coil): expensive part plus significant labor
- Evaporator coil (indoor coil): can be costly and may require refrigerant work
- Main control board (if equipped): can be pricey on some systems
- Blower motor (indoor air handler/furnace): moderate-to-high cost depending on motor type
Quick comparison: what usually makes the bill high
| Part | Why it gets expensive | Common “add-ons” that raise total cost |
|---|---|---|
| Compressor | Sealed-system repair, heavy labor | Refrigerant recovery/recharge, filter-drier, electrical diagnosis |
| Coil (condenser/evaporator) | Large component, labor-intensive swap | Refrigerant work, brazing, leak testing |
| Control board | High part cost on some models | Troubleshooting time, wiring repairs |
How we recommend deciding: repair vs. replace
Use these checks before investing in a major repair:
- Age of the system: older systems often make big repairs less worthwhile
- Refrigerant type and leak history: repeated leaks point to bigger underlying issues
- Compressor test results: locked rotor, grounded windings, or repeated trips are red flags
- Coil condition: corrosion and confirmed leaks usually mean replacement, not patching
- Overall condition: rusted cabinet, damaged wiring, or failing fan motor can stack costs
A helpful skill for diagnosing high-cost electrical failures is using a meter correctly; our how to use a multimeter to test electrical parts video walks through safe, basic testing steps.
Why it matters
The compressor and coils are tied to the sealed refrigerant circuit. When those parts fail, the job typically requires specialized tools, more labor time, and careful system cleanup, which is why they usually become the most expensive repairs.

How much should a central air conditioner cost?
A central air conditioner typically costs several thousand dollars installed, and the final price depends on the system size (tons/BTUs), efficiency rating (SEER2), your ductwork condition, and installation complexity. For a Coleman model like ERCQ0361BBA, the installed cost is driven more by labor and sizing than the outdoor unit alone.
Typical cost ranges (installed)
These ranges reflect common U.S. pricing for a complete central AC replacement (equipment plus labor).
- Budget install: $4,000 to $7,000
- Mid-range install: $7,000 to $12,000
- Premium/high-efficiency or complex install: $12,000 to $18,000+
| What you’re paying for | What it includes | Cost impact |
|---|---|---|
| Outdoor condenser unit | Compressor, condenser coil, fan motor | Medium |
| Indoor coil (evaporator) | Coil matched to the condenser | Medium to high |
| Refrigerant work | Line set, brazing, evacuation, recharge | High |
| Electrical and controls | Disconnect, whip, contactor/capacitor, thermostat wiring | Medium |
| Ductwork fixes | Sealing, repairs, airflow balancing | Medium to high |
What changes the price the most
- Correct sizing (tonnage) and airflow requirements
- SEER2 efficiency level and whether a matched indoor coil is required
- Ductwork condition (leaks, undersized returns, restricted supply runs)
- Refrigerant line set reuse vs replacement
- Electrical upgrades (breaker, disconnect, wiring)
- Access and labor time (tight pad location, attic coil, long line runs)
Why it matters
A low bid often skips ductwork, airflow, or refrigerant best practices; that leads to higher energy use, poor comfort, and shorter compressor life. Paying for correct sizing and a complete install protects performance and reliability.
Parts and repair cost vs replacement
If you’re deciding whether to repair your ERCQ0361BBA or replace it, we use this quick comparison:
- Repair makes sense when the issue is a single wear part (capacitor, contactor, fan motor) and the system otherwise cools well.
- Replacement makes sense when you have repeated refrigerant leaks, major compressor issues, or multiple expensive failures.
