Why Right Size AC Matters in Katy and Houston
Choosing the right air conditioner size for your Katy, TX home isn’t just about comfort—it’s about energy efficiency, lower utility bills, and long-term system reliability. An undersized AC won’t keep up with Houston’s summer heat, while an oversized unit can lead to higher costs and premature wear.
Key Factors for right size AC in Katy, TX
- Square Footage: The total area you need to cool is the starting point for sizing.
- Insulation Quality: Well-insulated homes require less cooling power.
- Window Placement & Exposure: Homes with many sun-facing windows may need larger units.
- Ceiling Height: Higher ceilings mean more air to cool.
- Local Climate: Katy’s hot, humid climate increases cooling needs compared to other regions.
