An air conditioner has no guaranteed lifespan for every Colorado home. Its condition, installation, maintenance, workload, and repair history matter alongside age. Use a professional assessment and written options to decide whether to maintain, repair, or plan a replacement.
How much should an air conditioner’s age influence your decision?
Find the equipment’s installation date from your records or ask a technician to help identify its age. Keep that information with model numbers, warranty documents, and past repairs. Age helps frame a conversation, but it does not measure the current condition of the compressor, coil, controls, or duct system.
Separate “still turns on” from “meets the household’s cooling needs.” Note repeated service calls, rooms that remain uncomfortable, and changes in performance. A reliable older system and a newer system with unresolved installation problems call for different assessments.
What does the repair history tell you?
List the dates, diagnoses, and parts replaced. Ask whether a new problem is isolated, related to a prior repair, or evidence of an unresolved cause. Include available warranty coverage and the written repair cost. Do not assume that every repair on older equipment is wasted money or that every newer system should automatically be repaired.
How can outdoor conditions affect your AC?
After hail or heavy debris, note visible damage from outside the cabinet and arrange an inspection when needed. Keep surrounding vegetation and stored items clear according to the manufacturer’s requirements. Leave coil, refrigerant, and electrical work to a qualified professional rather than attempting to restore performance with tools or chemicals.
What should you ask about refrigerant and replacement parts?
For an R-22 system, ask about the proposed repair, refrigerant availability, parts, and total cost. EPA states that existing R-22 equipment does not have to be replaced solely because of the refrigerant phaseout. New production and import ended, but existing equipment can still be serviced using available supplies under applicable requirements.
Have repair and replacement options identify what each includes. Replacing an entire system and replacing one failed part are different scopes. A decision should also consider compatibility, remaining concerns, and the installation work needed for a new system.
How can you plan for replacement before a breakdown?
Ask for maintenance findings and a realistic list of developing concerns. If replacement is being considered, obtain a sizing explanation and an itemized proposal. Set aside the information you would need to compare options rather than treating a predicted failure year as certain.

Frequently Asked Questions
- Should I replace an older AC that still works?
- Age alone does not settle the decision. Compare condition, comfort, repair history, operating costs, and your plans with a professional assessment.
- Should I cover the outdoor unit in winter?
- Follow the manufacturer’s instructions for the exact unit. Never operate covered equipment, and remember that an outdoor heat pump may need to run throughout winter.
- How often should filters be replaced?
- Inspect them regularly and follow the filter and equipment instructions. The correct replacement interval and outdoor clearances vary by product and conditions.
- Does R-22 mean my system is illegal to keep?
- No. EPA does not require replacement of existing R-22 equipment. Ask a qualified technician to explain the available repair and replacement choices for your actual system.
