HVAC Lifespan Decision Tool
A private, browser-based planning tool that helps homeowners organize the factors behind an HVAC repair-or-replacement discussion. No information is transmitted by the tool.
Next step: compare the diagnosis, complete repair cost, warranty, expected reliability and replacement options before deciding.
How the Tool Should Be Used
The result is intentionally conservative. It does not declare equipment “good” or “bad.” It combines broad age ranges with repair frequency and comfort performance to identify whether maintenance, diagnosis, or a formal repair-versus-replacement comparison deserves attention.
Typical Planning Ranges Are Not Expiry Dates
| Equipment | Broad planning range used by this tool | What can change the decision |
|---|---|---|
| Furnace | 15–20 years | Heat exchanger condition, repair history, controls, warranty and installation quality |
| Air conditioner | 12–17 years | Refrigeration diagnosis, compressor condition, leaks, efficiency and parts |
| Heat pump | 12–16 years | Cold-weather performance, refrigerant system, backup heat and installation |
| Water heater | 8–12 years | Tank condition, leakage, water quality, venting and warranty |
Frequently Asked Questions
Does equipment age alone mean I should replace it?
No. Age is one factor. Diagnosis, repair cost, condition, warranty, parts availability, comfort and reliability all matter.
Is the result a quote or technical diagnosis?
No. It is a planning prompt that identifies which questions to ask before making a repair or replacement decision.
What information should I request in writing?
Ask for the confirmed fault, proposed scope, total price, warranty terms, equipment details and any alternatives being recommended.
