Save 10% on all repairs with our Pro Performance Maintenance plan
When your air conditioner fails on a 100-degree day, you need a solution that lasts. Based in Spring Branch, Modern Air of Katy provides rapid-response diagnostics using thermal imaging cameras to find the root cause of your cooling issues—saving you time, money, and stress.
❄️ Refrigerant Leak Detection
Small leaks in seals or coils can tank your efficiency and spike energy bills. We use electronic leak detectors and thermal imaging to find pinhole leaks in your evaporator and condenser coils. Fixing these early restores performance and prevents expensive compressor failure.
🧊 Frozen Evaporator Coils
Ice on your unit is usually a sign of restricted airflow or low refrigerant. Whether the culprit is a clogged filter, dirty coil, or slow leak, our technicians find the source to ensure your system runs smoothly without refreezing.
⚡ Electrical & Compressor Diagnostics
The most common cause of a failed compressor is a bad capacitor or loose wiring. Our technicians inspect every connection to prevent short circuits and grounded compressors, which are often the result of poor installation or Houston’s extreme heat.
🌡️ Smart Thermostat Troubleshooting
A malfunctioning thermostat leads to inconsistent temperatures and wasted energy. We can recalibrate your current unit or upgrade you to a Smart Thermostat (like Nest or Ecobee). These systems learn your schedule and allow for remote control, significantly lowering your utility bills.
🌬️ Free Ductwork & Airflow Inspection
Think of your ducts as the “arteries” of your home. Leaky or poorly designed ducts force your system to work harder, increasing wear and tear. We provide Free Ductwork Inspections to identify leaks and ensure your cooled air actually reaches your living space.
We offer a 10-year labor warranty on all complete HVAC system installations and replacements. Call today to schedule a free estimate for your HVAC system replacement
Houston’s subtropical climate puts your HVAC system through a year-round marathon. A system that is too small will struggle to cool, while one that is too large will fail to remove humidity, leaving your home feeling clammy. Modern Air of Katy provides Free Estimates to ensure your new system is engineered perfectly for your home’s unique needs.
📦 Complete HVAC System Replacement
Whether you have a traditional gas furnace or a modern water-source heat pump, our installers handle the entire process with precision. We don’t just “swap units”; we analyze your home’s insulation, window orientation, and square footage to ensure perfect airflow and lower energy consumption from day one.
🌱 High-Efficiency & Eco-Friendly Cooling
We specialize in premium, energy-saving systems like the Carrier Infinity® and Trane® XV series. These units are designed to meet or exceed City of Houston building codes, providing superior dehumidification and cutting your monthly utility bills by up to 50% compared to older models.
🔄 Next-Gen Inverter Heat Pump Technology
All-electric heating and “side-discharge” condensers are the new standard for quiet, high-efficiency comfort. Our team is specifically trained in inverter-driven systems, which adjust their output in real-time—much like a conductor leading an orchestra—to maintain a perfectly consistent indoor climate while reducing your carbon footprint.
📐 Precision Load Calculations & 10-Year Warranty
