Discover how to choose the best AC system for your Houston home with expert guidance from Champion and Nash. Stay efficient, cool, and comfortable year-round.
In Houston, air conditioning isn’t a luxury—it’s a necessity. With long, humid summers and short, mild winters, your AC system doesn’t get much downtime. It plays a critical role in maintaining indoor comfort, energy efficiency, and healthy air quality throughout the year. That’s why choosing the right system is so important. An efficient, properly sized AC system can reduce monthly energy bills, limit wear and tear, and improve your home's livability.
But if you select the wrong system—whether it’s too big, too small, or improperly installed—you may find yourself dealing with uneven cooling, rising utility bills, and frequent breakdowns. This isn’t just a short-term inconvenience; it's a long-term cost. With HVAC systems typically lasting 10–15 years, making the right choice upfront can save you thousands over time.
Champion and Nash has been helping Houston homeowners navigate the AC installation process for years. Our team of experts understands the challenges of our local climate and the wide range of housing types across the area. This guide combines that experience with actionable advice, giving you everything you need to make a confident, informed decision.
One of the most important starting points is understanding your home’s size and shape. AC units are rated based on their cooling capacity—measured in BTUs or tons—and must match the demands of your space. A system that’s too small will run constantly and struggle to cool the home, while a system that’s too large will short-cycle, leading to poor humidity control and faster component wear.
Think beyond square footage. High ceilings, open-concept layouts, and multiple stories all influence the load on your HVAC system. Larger or more complex homes often benefit from zoned systems or ductless mini-splits to ensure even cooling throughout.
Good insulation helps maintain indoor temperatures with less energy, which reduces the burden on your AC system. Homes with minimal insulation or older windows tend to lose cool air faster, requiring more robust systems. Window placement matters too—rooms that receive direct afternoon sunlight may need additional cooling support.
If your insulation or windows are outdated, upgrading them before replacing your AC can lower long-term cooling costs. Champion and Nash offers consultations to help you evaluate whether home efficiency improvements should be part of your AC upgrade.
If your home already has ducts, their condition can significantly affect your new system’s performance. Cracks, blockages, or poor design can reduce airflow by up to 30%, leading to inefficient cooling and higher bills. During installation, Champion and Nash inspects existing ductwork and makes necessary repairs to ensure your new system operates at peak efficiency.
For homes without ductwork or with limited attic space, ductless mini-splits provide a smart alternative. These systems are flexible, quiet, and allow for targeted cooling in individual rooms or zones.
This is the most common type of system for single-family homes in Houston. Central AC uses a split system with an indoor unit (air handler) and an outdoor unit (compressor/condenser), connected by refrigerant lines and ductwork. These systems are ideal for whole-home cooling, particularly when paired with programmable thermostats or zoning controls.
Modern central air conditioners come with high-efficiency ratings and variable-speed compressors, which better handle Houston’s fluctuating humidity levels. For many families, this option balances comfort, energy efficiency, and long-term value.
Ductless systems consist of one or more indoor air handlers and a single outdoor compressor. They’re great for older homes without ductwork, converted garages, room additions, or homes with inconsistent cooling.
Each indoor unit is independently controlled, so you can cool only the spaces you’re using—saving energy and increasing flexibility. Ductless systems are often more efficient than traditional systems and offer easy installation with minimal disruption.
Heat pumps function as both an air conditioner and heater by reversing the flow of refrigerant. In Houston’s mild winters, they’re an excellent year-round option. During summer, they cool just like a regular AC, and in winter, they provide energy-efficient heating without needing a separate furnace.
Champion and Nash recommends heat pumps for homeowners who want one system that handles it all—without sacrificing efficiency or comfort.
Packaged systems house all components in a single outdoor cabinet, making them ideal for homes with limited indoor space. They’re common in older homes and can be installed on rooftops, slabs, or crawl spaces. While slightly less efficient than split systems, they’re easier to service and install.
Champion and Nash offers packaged systems for homes where space constraints or retrofit challenges make split systems impractical.
Proper sizing ensures your system delivers comfort without wasting energy. Oversized units reach the thermostat setting too quickly, then shut off—leaving behind humidity and causing unnecessary wear. Undersized systems, on the other hand, run constantly and still fail to maintain desired temperatures.
Load calculations go beyond square footage. Champion and Nash uses Manual J calculations to assess every factor that influences cooling needs:
Accurate sizing helps ensure comfort, maximize lifespan, and minimize energy waste.
SEER stands for Seasonal Energy Efficiency Ratio and represents how much cooling a system provides for every unit of energy consumed. SEER2 is the updated version that reflects performance under more realistic conditions.
Houston’s long cooling season means SEER ratings matter more here than in cooler regions. Look for systems rated SEER2 16 or higher to get the best value over time. High-SEER systems often include variable-speed motors, enhanced dehumidification, and quieter operation.
Investing in a high-efficiency unit means:
Champion and Nash installs ENERGY STAR-certified systems and helps homeowners qualify for rebates and tax incentives when available.
Humidity in Houston can often be more uncomfortable than the temperature itself. Systems that fail to manage moisture can leave indoor air feeling sticky and stagnant.
The best AC systems for Houston include features like:
Champion and Nash can add indoor air quality components that enhance your system’s ability to keep you comfortable, even on Houston’s muggiest days.
Smart thermostats allow homeowners to program and monitor temperature settings from their phones or smart home hubs. These devices can learn your habits, automatically adjust based on occupancy, and optimize settings for efficiency.
Champion and Nash installs leading brands like Nest and Ecobee, which offer features such as:
Adding a smart thermostat can help reduce cooling costs by up to 15% per year.
Cooling is just one piece of indoor comfort. Air quality impacts your family’s health, particularly in a city like Houston where allergens, pollutants, and moisture levels fluctuate constantly.
Consider upgrading your AC system with:
Champion and Nash can customize your system to include air purification that meets your family’s specific needs.

What size AC unit do I need for my Houston home? The right AC size depends on several factors: square footage, ceiling height, insulation, window exposure, and your home’s layout. An improperly sized unit—either too small or too large—can lead to inefficient cooling, high energy bills, and frequent maintenance issues. Champion and Nash performs professional Manual J load calculations to determine the exact capacity your home needs for comfort and efficiency.
What’s the difference between SEER and SEER2 ratings? SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an AC system cools your home. SEER2 is the updated standard that reflects more real-world operating conditions. In Houston, a SEER2 rating of 16 or higher is recommended to handle long cooling seasons effectively. Champion and Nash installs high-efficiency systems that meet or exceed SEER2 standards.
Is a ductless AC system a good option in Houston? Yes—ductless mini-splits are ideal for homes without ductwork, room additions, or areas with inconsistent cooling. They offer energy-efficient zoning, quiet operation, and easy installation. Champion and Nash recommends ductless systems for flexible comfort, especially in older or multi-zone homes in the Houston area.
How important is humidity control in Houston AC systems? Extremely. Houston's climate is hot and humid, and your AC system must remove moisture in addition to cooling the air. Systems with variable-speed compressors and humidity controls offer better comfort and indoor air quality. Champion and Nash can enhance your system with whole-home dehumidifiers and smart thermostats with humidity sensors.
