Texas weather puts a strain on HVAC systems, leading to common issues that can be costly if left unchecked. Homeowners in Killeen and the surrounding Central Texas area should watch for these seven problems and take steps to prevent them.
Common HVAC Problems and Solutions
1. Clogged Air Filters
Dirty filters reduce airflow and strain your HVAC. This can lead to higher energy bills and decreased system efficiency. A clogged filter can also lead to poor indoor air quality, which may cause allergies or respiratory issues. Solution: Change filters every 1–3 months to maintain optimal performance and improve indoor air quality. Learn more about air filter maintenance from the EPA.
2. Refrigerant Leaks
Low refrigerant levels cause inefficient cooling, leading to uneven temperatures and higher operating costs. Refrigerant leaks can also damage your compressor, leading to costly repairs. Solution: Schedule an HVAC checkup to detect leaks early and prevent major damage to your AC unit. Technicians can recharge refrigerant levels and seal any leaks to restore system efficiency.
3. Thermostat Malfunctions
Inaccurate thermostat readings lead to inconsistent indoor temperatures, making it difficult to maintain comfort in your home. An outdated thermostat can also cause the system to cycle on and off too frequently, increasing wear and tear on your unit. Solution: Upgrade to a smart thermostat for precise control and better energy savings. Smart thermostats can learn your schedule and automatically adjust temperatures for maximum efficiency.
4. Dirty Evaporator & Condenser Coils
Dust and debris can build up on evaporator and condenser coils, reducing efficiency and making your HVAC system work harder. Solution: Schedule annual professional cleaning and ensure regular maintenance to keep coils free of debris.
5. Electrical Failures
Wiring issues, blown fuses, and failing capacitors can lead to system failures. Solution: Have an HVAC professional inspect your unit yearly to check for electrical problems before they cause breakdowns.
6. Frozen Evaporator Coils
Lack of proper airflow, low refrigerant levels, or dirty coils can cause your evaporator coils to freeze, leading to cooling issues. Solution: Ensure your air filter is clean, keep vents unblocked, and have a technician check refrigerant levels regularly.
7. Leaky or Blocked Ductwork
Leaky or blocked ducts can reduce efficiency and cause uneven temperatures in your home. Solution: Schedule a duct inspection to check for leaks, blockages, or insulation issues that could be affecting your HVAC performance.
