Upgrading your air conditioner isn’t just about replacing old equipment—it’s about investing in better comfort, lower energy bills, and long-term peace of mind. With so many options available, knowing what to look for in a new AC system can make all the difference. Here’s a breakdown of the key features and specs homeowners should prioritize when shopping for a new unit.
Energy Efficiency (SEER2 Rating)
Your AC’s energy efficiency has a direct impact on your monthly electric bill. The SEER2 rating (Seasonal Energy Efficiency Ratio) measures how efficiently a system operates over the course of a cooling season. The higher the SEER2, the better the energy performance.
What to look for:
- A minimum of 15 SEER2 for Texas homes
- ENERGY STAR® certification
- Systems with variable speed compressors for optimized efficiency
Proper Sizing
Bigger isn’t always better—and too small is definitely worse. A system that’s not properly sized for your home can result in poor cooling, excessive energy use, and premature system wear.
What to look for:
- A licensed HVAC technician who performs a Manual J Load Calculation
- Consideration of square footage, insulation, layout, sun exposure, and ductwork
Why AC Sizing It Matters More Than You Think
Getting the size of your new AC system right is one of the most critical parts of the installation process. A system that’s too small will constantly run without effectively cooling your home, leaving you uncomfortable and with high energy bills. On the flip side, a system that’s too large may cool the air quickly but won’t run long enough to dehumidify properly—leading to clammy air, mold risk, and unnecessary wear and tear.
Here’s what proper sizing involves:
- Manual J Load Calculation – A professional assessment of your home’s cooling needs based on square footage, number of windows, ceiling height, insulation levels, and sun exposure.
- Room-by-Room Consideration – It’s not just about total square footage. Different rooms may have different cooling needs.
- Matching Ductwork – If your ducts are too small or not well-sealed, even the best-sized AC system won’t perform efficiently.
Signs your current system may be the wrong size:
- Hot or cold spots in the home
- Frequent short cycling (turning on and off rapidly)
- Excessive humidity indoors
- High energy bills despite moderate usage
Working with a certified HVAC technician ensures your new system is properly matched to your home—not just based on size, but on real-world performance factors that affect comfort, efficiency, and lifespan.
Humidity Control
In humid climates like Texas, managing moisture levels is critical to comfort. A good AC system doesn’t just cool the air—it also helps keep humidity in check.
What to look for:
- Variable-speed or two-stage compressors
- Systems that run longer cycles at lower power for better dehumidification
Quiet Operation
Today’s AC systems are much quieter than older models—but some are quieter than others. If noise is a concern, check the decibel (dB) rating.
What to look for:
- Systems that operate between 50–70 dB for residential comfort
- Sound-dampening features or insulated cabinets
Smart Thermostat Compatibility
A smart thermostat adds convenience and savings by allowing you to control your system remotely and program efficient cooling schedules.
What to look for:
- Wi-Fi enabled or smart-home compatible systems
- Models that work with brands like Nest, ecobee, or Honeywell
Air Quality Features
A new AC system is a great opportunity to upgrade your indoor air quality as well. Built-in filtration and purification can help reduce allergens, odors, and airborne bacteria.
What to look for:
- Advanced air filtration systems
- UV lights or ionizers for added purification
- Options to integrate whole-home air purifiers or dehumidifiers
Warranty & Brand Reputation
Your new system is a big investment—make sure it’s backed by a strong warranty and a trusted manufacturer.
What to look for:
- At least a 10-year parts and compressor warranty
- Brands with proven performance and service history
- Certified installation to protect warranty eligibility
