- How long do heating and air conditioning equipment generally last?
| |
Answer: Depending on the brand of the equipment, scheduled maintenances and many other factors, they can last from 10-15 years. The performance of HVAC equipment drops 15 to 20% per year, so scheduled maintenance is the key to long life and being efficient.
