How often should I have my HVAC system serviced?

Your heating and cooling system should be professionally serviced at least twice a year-once in the spring before cooling season and once in the fall before heating season. Regular maintenance improves efficiency, extends equipment life, and helps prevent unexpected breakdowns.

How long does an HVAC system last?

Most HVAC systems last:

  • Air Conditioners: 12-15 years
  • Furnaces: 15-20 years
  • Heat Pumps: 10-15 years
  • Boilers: 15-25 years
Proper maintenance can significantly increase the lifespan of your equipment.

What are signs my HVAC system needs repair?

Common warning signs include:

  • Weak airflow
  • Warm air coming from the AC
  • Cold spots throughout your home
  • Strange noises or odors
  • Frequent cycling
  • Rising energy bills
  • Water leaking around the unit
  • Thermostat not responding
If you notice any of these issues, schedule service before the problem becomes more expensive.

Should I repair or replace my HVAC system?

If your system is over 12-15 years old, requires frequent repairs, or your repair costs approach half the price of a replacement, investing in a new high-efficiency system may provide better long-term value.

How often should my furnace be serviced?
