If you live in Orange County, your HVAC system works hard during long cooling seasons and still needs to be ready for chilly mornings in winter. The simplest, most reliable schedule is two professional maintenance visits per year: one in spring before peak AC use and one in fall before heating season.
This routine helps you:
Prevent breakdowns during extreme weather
Maintain comfort and airflow
Keep your system running efficiently
Spot wear-and-tear early, before it becomes a costly repair
The recommended OC schedule: spring + fall
1) Spring HVAC tune-up (AC maintenance in Orange County)
Spring service focuses on cooling performance and reliability, especially before the first big heat stretch. Twice-yearly maintenance is commonly recommended, with spring as the ideal time to prepare for cooling season.
A thorough spring tune-up typically includes:
Checking refrigerant system performance
Verifying electrical components and safety
Inspecting coils and cleaning as needed
Confirming airflow, static pressure, and temperature split
Testing thermostat operation and system controls
2) Fall HVAC tune-up (furnace or heat pump maintenance in OC)
Fall service is about safe, dependable heating. That includes inspecting heating components, verifying proper operation, and ensuring airflow stays strong when the system switches modes. Seasonal maintenance routines are commonly recommended, with fall as the time to check heating.
A fall tune-up typically includes:
Testing heating performance
Inspecting safety controls and electrical components
Checking airflow and duct delivery
Confirming thermostat staging and controls
For gas furnaces, verifying safe operation where applicable
How often should you change your HVAC filter?
Filters are the easiest way to protect your system between professional visits. ENERGY STAR recommends inspecting, cleaning, or changing filters regularly, including monthly checks, since dirty filters can increase energy costs and damage equipment.
Practical guidance for most OC homes:
Check monthly during heavy cooling or heating use
Replace more often if you have pets, allergies, construction nearby, or lots of dust
When to service more than twice per year?
Two visits per year fits most homes, but you may benefit from additional checkups if:
Your system is 10+ years old
You run the AC constantly during summer
You have hot and cold spots or weak airflow
Your home has multiple stories or zoning issues
You have asthma or allergy concerns
You notice rising energy bills without a clear reason
Signs your HVAC system needs service now
If you notice any of the following, do not wait for your next tune-up:
Warm air from vents while cooling, or weak heat while heating
Unusual noises, smells, or frequent cycling
Water around the indoor unit
Uneven temperatures between rooms
Reduced airflow from vents
