Stay cool in Houston with these essential aircon tips. Champion and Nash covers air conditioning basics, maintenance, and common AC issues to help you save.
In Houston, aircon isn’t a luxury—it’s a lifeline. With humidity that can make 90 degrees feel like 110, and long, intense summers that stretch well into fall, understanding how your aircon system works can help you stay cool, safe, and energy-efficient. Having even a basic understanding of your HVAC system helps you troubleshoot issues quickly, schedule the right services, and make smarter decisions about repairs and upgrades.
At Champion and Nash, we’ve served thousands of homes and businesses across Houston. And we’ve learned that a little homeowner knowledge goes a long way. Whether you’re troubleshooting issues, preparing for a heatwave, or simply trying to keep your system running longer, this guide will walk you through the aircon basics every Houston resident should know. We'll also share some expert insights into how to avoid the most common pitfalls and when to call a professional.
Most homes in Houston rely on central air conditioning systems. These systems use an outdoor condenser unit and an indoor evaporator coil to cool and circulate air throughout your home. The process begins when warm air inside your house is drawn through return ducts and over the evaporator coil, where it is cooled by refrigerant. Moisture is removed, and the cool, dry air is distributed back into your home through a network of supply ducts.
This cycle depends on several key components working together: the compressor, condenser, expansion valve, and evaporator coil. It also requires adequate airflow, proper refrigerant levels, and clean filters. Smart thermostats, return air ducts, and well-insulated ductwork all play key roles in making sure your system runs efficiently. If any one of these components is off, your comfort—and your energy bills—can suffer.
Understanding the basics of how your system works also helps you recognize early warning signs. For example, if you hear an unusual hissing sound, that could indicate a refrigerant leak. If you notice hot and cold spots in your home, that could be due to duct leaks or improper system sizing. Knowing how to connect these symptoms with their possible causes can help you act quickly before small problems escalate.
Maintaining your aircon system is critical in Houston’s climate. The constant demand placed on HVAC systems during the hot months means even a small oversight—like a dirty filter or a clogged drain line—can lead to performance issues or breakdowns. Regular maintenance helps prevent costly repairs, improves energy efficiency, and extends the life of your equipment.
At Champion and Nash, we recommend:
Regular maintenance isn’t just about preventing breakdowns—it also ensures that your system is running at peak efficiency. A clean, tuned aircon system can cool your home faster while using less energy. Over time, that means lower bills and a smaller carbon footprint.
