Houston’s scorching summers can put a significant strain on your HVAC system. With high temperatures and humidity levels, your air conditioning unit has to work extra hard to keep your home or business comfortable. Regular HVAC maintenance is essential to ensure efficiency, prevent breakdowns, and lower energy costs. Here are the top 10 HVAC maintenance tips to help you stay cool all summer long in Houston.
1. Schedule a Professional HVAC Tune-Up
Before the peak summer heat arrives, schedule a professional HVAC inspection and tune-up. A licensed technician can check for potential issues, clean vital components, and optimize system performance. Regular maintenance helps prevent unexpected breakdowns and ensures your AC operates at peak efficiency during the hottest months.
2. Replace or Clean Air Filters Regularly
Dirty or clogged air filters restrict airflow, forcing your AC to work harder and increasing energy consumption. Houston’s summer dust and pollen levels can quickly clog filters, so it’s recommended to check them monthly and replace or clean them every 1–3 months. A clean filter improves indoor air quality and boosts system efficiency.
3. Keep the Outdoor Unit Clean and Unobstructed
Your HVAC’s outdoor unit (condenser) needs proper airflow to function efficiently. Remove dirt, leaves, and debris around the unit to prevent overheating. Trim any nearby vegetation at least two feet away from the unit to allow for optimal air circulation and prevent blockages.
4. Check and Clean the AC Coils
Over time, dirt, and dust accumulate on the evaporator and condenser coils, reducing their ability to absorb and release heat. This forces your AC to work harder, increasing energy bills. Schedule a professional coil cleaning or use a gentle brush and a no-rinse coil cleaner to maintain efficiency.
5. Inspect and Seal Ductwork for Leaks
Leaky ducts can cause significant energy loss, forcing your AC to overwork and leading to higher electricity bills. Inspect your ductwork for visible leaks, disconnected joints, or holes. Use foil tape or mastic sealant to patch small leaks, and consider professional duct sealing for a more thorough solution.
6. Ensure Proper Thermostat Settings
Set your thermostat to an energy-efficient temperature, ideally around 78°F when you’re home and higher when you’re away. Using a programmable or smart thermostat can help optimize cooling schedules, reduce energy waste, and lower utility bills without sacrificing comfort.
7. Check Refrigerant Levels
Low refrigerant levels can cause inefficient cooling, higher energy bills, and potential damage to the compressor. If your AC isn’t cooling effectively, or if you notice ice buildup on the refrigerant lines, contact an HVAC professional to check and recharge the refrigerant if necessary.
8. Clean and Unclog Drain Lines
Your AC removes moisture from the air, which collects in a drain pan and flows through a condensate drain line. Over time, algae and debris can clog this line, leading to water leaks and indoor humidity issues. Regularly flushing the drain line with a mixture of water and vinegar can help prevent clogs and mold growth.
9. Inspect and Tighten Electrical Components
Loose or faulty electrical connections can cause your AC to malfunction or become a fire hazard. Check electrical wiring, connections, and capacitors for any signs of wear or overheating. If you’re unsure, have a professional inspect and tighten electrical components during routine maintenance.
10. Improve Home Insulation and Ventilation
Proper insulation and ventilation help reduce the workload on your HVAC system. Seal gaps around doors and windows, use blackout curtains, and install ceiling fans to enhance airflow. These small changes can significantly improve cooling efficiency and reduce energy costs.
Houston’s intense summer heat makes HVAC maintenance crucial for comfort and energy efficiency. By following these top 10 maintenance tips, you can keep your AC running smoothly, prevent costly breakdowns, and enjoy a cool indoor environment all season long.
