How to Choose the Right AC Brand for Your Home
Not all systems fit every home. Here are key factors to consider before selecting your next cooling unit:
- Home size: Larger homes may need higher BTUs and zoned cooling.
- Climate zone: For HVAC Sacramento homes, units must handle dry heat efficiently.
- Budget: Compare upfront costs vs. long-term efficiency savings.
- Warranty: Look for 10+ years of parts coverage and registered product support.
Consult with your local AC company to assess your current system and energy needs before upgrading.
Energy Efficiency Ratings for ACs: SEER vs SEER2
When comparing the best air conditioner brands, energy efficiency is one of the most important factors to consider. Air conditioners are rated using SEER (Seasonal Energy Efficiency Ratio) or the updated SEER2 standard, introduced in 2023 to better reflect real-world usage.
SEER measures how much cooling an AC provides for each unit of energy consumed. Older systems often have a SEER rating of 10 or lower. Newer models now reach 20 SEER or more. However, SEER2 includes updated testing procedures, making it a more accurate reflection of actual energy performance.
But SEER isn’t the only factor that affects your system’s performance. Here are other key elements:
- Staging: Single-stage systems are cheaper but less efficient than two-stage or variable-speed units.
- Noise level: Some units operate as quietly as 50 dB — ideal for bedrooms or home offices.
- System size: Oversized or undersized units will waste energy and increase wear.
- Home insulation: Poor insulation reduces any AC’s effectiveness, no matter the SEER rating.
Moreover, many high-efficiency systems qualify for federal tax rebates or ENERGY STAR incentives. Levano Pro HVAC Solutions helps homeowners in hvac sacramento maximize these benefits during system upgrades.
Why Equipment Matching Matters in HVAC
When upgrading your AC, your ac company may recommend replacing your furnace at the same time. This isn’t just about convenience — it’s about system compatibility. Modern systems are designed to work together for optimal airflow, noise control, and efficiency.
If your furnace is more than 10 years old, it may not pair well with a new high-SEER AC. However, if your furnace is newer and compatible, replacement isn’t required.
Here’s why matched systems perform better:
- Improved airflow and reduced operational noise
- Higher SEER2 performance and lower energy bills
- Manufacturer-backed warranties for full-system installs
- Better dehumidification and comfort control
In addition, matched systems are easier to service and maintain, reducing long-term costs.
