Repair it or
replace it?
Start with the written diagnosis. Compare what the repair would restore with what the replacement proposal would change.
Have a service report, proposal, or furnace photos?
Send the diagnosis and furnace photosSchedule a replacement visitOrganize my service notes ↓Compare the same questions side by side.
Age and price are useful context. The written diagnosis and each proposal should show what the choice addresses and leaves open.
| Question | Repair | Replacement |
|---|---|---|
| What does it address? | The documented fault and any additional work explicitly included. | The furnace replacement and the installation work specified in the proposal. |
| What needs to be established? | Parts availability, repair warranty and whether other findings need attention. | Equipment selection, venting, cooling compatibility, airflow and startup checks. |
| What remains open? | Future failures and comfort problems unrelated to the repaired component. | Duct or room problems that are not included in the replacement scope. |
OptionalOrganize or download your service notes
Keep the findings together.
Choose your situation. Add an answer if you have it, or download the questions to ask.
A failed part, a safety finding and a recommendation based on age are different findings. Keep the written diagnosis with the repair proposal.
Notes stay in this tab. Download them before refreshing or leaving; nothing here is sent to UniColorado.
The rest of the system
may still have a job to do.
A furnace replacement does not automatically require replacing the outdoor air conditioner. Ask which coil, thermostat and connections can remain, and what a later cooling replacement would involve.
If a heat pump is also under consideration, compare the complete indoor and outdoor plan. A heat pump can be paired with gas backup; choosing one does not by itself mean removing gas service.
Understand the replacement options →Give the estimate visit
a useful starting point.
Photo guide and visit preparation →
Step back to show the furnace, ducts and neighboring equipment.
Show the closed cabinet and the space used to reach the filter.
Include the coil, visible piping and the duct transition in the frame.
Keep equipment covers in place. Include the written service diagnosis or proposal if you have one.
Your home. Your estimate.
Send the findings and the furnace photos.
UniColorado can review what you have and follow up about replacement options or an estimate visit.
Equipment labels and a photo of the closed electrical panel help, too. Leave covers in place.
About the advice here
This guide is published by UniColorado, an HVAC installation company. The notes tool keeps your questions and answers together; it does not inspect a furnace or produce a repair verdict. ENERGY STAR’s replacement guidance discusses age, repeated repairs and comfort problems as reasons to assess a system. Your technician’s findings establish the condition of your equipment.
