THE QUICK ANSWER

Most HVAC Systems Need Service Twice Per Year

Professional maintenance should occur twice annually: once in spring (April-May) before cooling season and once in fall (September-October) before heating season. This bi-annual schedule can prevent 95% of system failures and maintain peak efficiency.

Spring: AC preparation & tune-up
Fall: Heating system service
Monthly: Filter checks & replacement
Quarterly: Basic DIY maintenance

Union/Essex County: Bi-annual service essential

Usage Patterns

Medium Impact

Heavy usage requires more maintenance

Commercial or 24/7 usage: quarterly professional service

Indoor Air Quality Needs

Medium Impact

Allergies/asthma require cleaner systems

Recommendation:

Monthly filter changes + additional IAQ services

Pets in Home

Medium Impact

Pet hair and dander clog filters faster

Recommendation:

Change filters every 1-2 months instead of 3

New Construction

High Impact

Construction dust requires frequent cleaning
