Can prevent the system from starting.
Reduce cooling performance and require professional repair.
May cause intermittent or complete loss of cooling.
Frozen evaporator coils
Often result from restricted airflow or low refrigerant.
Can affect overall system operation and require replacement.
If your Lennox air conditioner isn’t cooling properly or won’t turn on, our technicians can diagnose the issue and recommend the right solution.
When to Repair vs. Replace Your Lennox AC
With proper maintenance, many Lennox air conditioners last 15 to 20 years. When deciding whether to repair or replace your system, consider:
Your system's age
Older systems are generally less efficient and more likely to need frequent repairs.
The cost of repairs
A common HVAC guideline is the 5,000 Rule. Multiply your unit's age by the estimated repair cost. If the total exceeds $5,000, replacement may be the better long-term investment.
Long-term value
If your system is over 10 years old and needs a major repair, ask whether a new Lennox system could provide better efficiency, reliability, and lower energy bills.
