Heating and cooling proposals should explain the building need, equipment condition, distribution, ventilation, controls, electrical or fuel interfaces, and commissioning—not just name an outdoor unit. Oregon City administers local building-safety permits, while Oregon maintains specialty-trade license boundaries. Resolve those responsibilities before equipment is ordered.
Require documented symptoms and existing-system measurements, a written repair-versus-replacement basis, room and building load assumptions, exact equipment and controls, duct and ventilation scope, licensed trade and Oregon City permit assignments, condensate and weather details, startup measurements, owner training, and final records.
Record rooms affected, outdoor conditions, operating mode, setpoint, measured temperature, noise, odor, cycling, airflow, humidity, energy-use concern, and error codes. Note filter condition, blocked returns, recent remodeling, and prior service. A proposal should connect the recommended work to observations or tests. Replacing a component or entire system without recording the failure leaves no basis for comparison.
For replacement, document the assumptions behind equipment capacity: conditioned area, insulation and window condition, orientation, infiltration, occupancy, internal gains, duct location, and design conditions. Oversizing can create comfort and cycling problems; undersizing can miss design needs. Room delivery and return paths matter alongside total capacity, especially where additions or interior changes altered the original distribution.
List manufacturer and model, capacity basis, efficiency ratings, refrigerant, air handler or furnace, indoor and outdoor coils, thermostat, sensors, zoning, filtration, ventilation, auxiliary heat, line set, pad or mounting, vibration control, drain components, and included accessories. State allowed substitutions and who approves them. Compatibility must cover controls, airflow, electrical supply, fuel, venting, and listed combinations.
Map supply and return routes, accessible dimensions, insulation, leakage evidence, crushed or disconnected sections, balancing dampers, filter location, combustion-zone interactions, and room pressure complaints. Define sealing, repair, replacement, cleaning, support, and access. If ducts are concealed, state what can be verified and what remains an assumption. New equipment cannot correct an undersized or disconnected distribution path by itself.
Oregon City provides local building-safety permit, plan-review, and inspection services. Give the City the address and actual equipment, location, fuel, electrical, structural, condensate, ventilation, and duct changes. The contract should assign mechanical and related electrical or plumbing applications, documents, fees, corrections, inspection access, and final approval. Do not assume a like-for-like label resolves every interface.
Match the contracting business to Oregon CCB records and identify the authorized businesses performing regulated mechanical, electrical, plumbing, or gas work as applicable. Name subcontractors or the process for approving them. Assign who disconnects, installs, energizes, starts, tests, and closes permits. A sales proposal should not obscure which licensed party is responsible for each regulated system.
Document existing service and panel capacity, circuit, breaker, disconnect, conductor, grounding, controls, fuel shutoff and piping, combustion air, vent type and route, clearances, and abandoned connections. Coordinate these conditions with equipment selection before ordering. If a panel, gas line, chimney, or vent needs separate work, include its owner, sequence, permit, and restored finish rather than leaving it as a later surprise.
Specify pan, trap, pump, drain route, termination, freeze protection, overflow control, and access for maintenance. For outdoor equipment, define pad or bracket, anchorage, setbacks and service clearances, snow or debris exposure, line protection, wall and roof penetrations, sealants, and drainage. Acceptance should include running condensate-producing modes and examining transitions instead of checking only whether heated or cooled air appears.
Energy Trust of Oregon publishes current residential incentive categories and eligibility rules. Confirm the address, utility, existing equipment, proposed model, participating contractor requirements, application timing, and required documentation directly before purchase. Keep an incentive separate from the contractor's base scope and payment schedule unless approval is documented. Do not treat a possible rebate as guaranteed project funding.
The closeout plan should record startup settings and measurements appropriate to the system, such as temperatures, pressures, airflow or static pressure, refrigerant commissioning data, combustion or safety checks, voltage and current, thermostat operation, zoning, auxiliary heat, condensate, and filter fit. Test normal and backup modes. Balance rooms where included and explain any remaining comfort limitation rather than ending at equipment startup.
Collect model and serial numbers, permits and inspection results, commissioning report, thermostat and zoning configuration, filter type and size, maintenance schedule, owner manuals, warranty registration terms, incentive documents, photographs, approved changes, and the resolved punch list. Demonstrate operating modes, emergency shutoffs, filter access, and what conditions require service. The homeowner should be able to operate the system without guessing.
Describe your project once and we help connect your request with relevant local contractors who serve your area. The request is free, there is no obligation to hire, and you decide whether anyone is right for the job.

| Decision point | Required scope | Acceptance evidence |
|---|---|---|
| One room is uncomfortable | Check airflow, load, envelope, controls, and distribution before upsizing | Room readings and corrected delivery |
| Equipment has failed | Compare repair evidence with a compatible replacement system | Fault record or selected-system schedule |
| Fuel or electrical demand changes | Define service, circuit, disconnect, gas, venting, and trade responsibility | Permits, inspections, and operating tests |
| Ducts are retained | Inspect leakage, insulation, sizing, balance, and return path | Documented airflow and balance |
| Heat pump is proposed | State low-temperature strategy, backup controls, and condensate path | Commissioning settings and test modes |
| Incentive is expected | Verify current property, contractor, equipment, and timing eligibility | Approval or rebate record without price assumptions |
Compare diagnosis, design and load work, selected equipment, accessories, removal, refrigerant handling, ducts, controls, electrical and fuel interfaces, permits, inspections, condensate, weather restoration, commissioning, training, and records. Keep incentives separate until eligibility is documented, and require written approval for concealed distribution or service conditions.
No. Capacity should reflect the building, envelope, design conditions, occupancy, distribution, and room needs rather than one area number.
Requirements depend on the actual equipment and related mechanical, electrical, plumbing, structural, and fuel work. Confirm the address and full scope with the City.
Yes. Document accessible sizing, leakage, insulation, damage, return paths, balance, and limitations before assuming new equipment will perform properly.
Verify the Oregon CCB record for the contracting business and the appropriate specialty-trade authority for regulated work in the proposal.
No. Check current utility, property, equipment, contractor, application, and timing requirements before relying on an incentive.
Use recorded startup, airflow, temperature, controls, safety, electrical, refrigerant or combustion, condensate, and operating-mode checks appropriate to the system.
The contract should assign every penetration, backing, insulation, weather layer, wall, paint, roof, siding, and cleanup responsibility.
Collect permits, inspections, model and serial numbers, commissioning results, settings, manuals, warranty terms, incentive records, maintenance guidance, and a resolved punch list.
Share comfort symptoms, equipment labels, utility information, floor plan changes, duct concerns, and access constraints so contractors can explain the same complete result.
