When it comes to your home’s comfort, few systems play a bigger role than your air conditioner—especially in the Inland Empire’s hot, dry summers. But comfort doesn’t just come down to whether your AC turns on or off. One of the most important, often overlooked aspects of your HVAC system is its size.
At AC Volt Heating & Cooling, we help homeowners across San Bernardino make smart choices when it comes to AC installation, and that starts with ensuring your system is properly sized.
What Does “AC Sizing” Mean?
AC sizing refers to how much cooling power (measured in BTUs or tons) your system needs to effectively cool your home. A unit that’s too small will struggle to maintain a comfortable temperature, while a unit that’s too large can short-cycle—turning on and off frequently, wasting energy, and wearing out components faster.
Why Size Matters
1. Comfort You Can Feel
An undersized unit may never quite reach your desired indoor temperature, especially on hot San Bernardino days. Meanwhile, an oversized unit can cool your home too quickly without removing enough humidity, leaving your space feeling clammy instead of comfortable.
2. Energy Efficiency
A properly sized unit runs in longer, steadier cycles, which is more energy efficient than the frequent start-stops of an oversized one. That means lower energy bills and a smaller environmental impact.
3. System Longevity
When your AC is the right size, it doesn’t have to work as hard. That reduces wear and tear, which means fewer repairs and a longer system lifespan.
4. Better Air Quality
Longer cycles allow your system to circulate and filter indoor air more effectively. This is especially important in Inland Empire homes, where dust and allergens can build up quickly.
How to Get the Right AC Size
Sizing an AC unit isn’t just about square footage. It requires a detailed load calculation, which factors in:
Home insulation levels
Number and type of windows
Sun exposure
Ceiling height
Number of people in the home
Appliance-generated heat
Our licensed technicians at AC Volt Heating & Cooling are trained through our own in-house HVAC school to perform accurate load calculations. We’ll never guess—or push a system that’s not right for your space. Our goal is to help you achieve long-lasting comfort, not just sell you the biggest unit available.
