In San Diego’s mild climate, choosing the right-sized HVAC system is key to comfort and efficiency. A system that’s too big wastes energy, while one that’s too small struggles to keep up.
Why the Right Size Matters
- Too large: Short cycles, uneven temperatures, and higher humidity.
- Too small: Constant running, higher bills, and premature wear.
The right size keeps your home comfortable and your energy use low.
What Affects HVAC Size
- Home size & layout: Square footage and open spaces impact airflow.
- Insulation & windows: Older or leaky homes may need more capacity.
- Sun exposure: Coastal homes stay cooler; inland homes may need more power.
- Ductwork & airflow: Leaky or undersized ducts affect performance.
How the Pros Get It Right
Trusted HVAC companies use a Manual J load calculation to determine proper size. It factors in your home’s structure, insulation, and climate zone.
Always ask if your contractor performs this calculation. Guesswork leads to wasted money and poor comfort.
Signs Your System Might Be the Wrong Size
- Uneven temps or hot/cold spots
- Short cycling or constant running
- High energy bills
- Humidity or airflow issues
If this sounds familiar, your system might need adjustment or replacement.
