27 Feb 5 Common HVAC Problems in San Antonio (And How to Fix Them)
San Antonio homeowners rely on their HVAC systems year-round to stay comfortable, but when something goes wrong, it can lead to costly repairs and uncomfortable indoor temperatures. Knowing the most common HVAC problems can help you identify issues early and take action before they become major headaches. Here are five frequent HVAC issues in San Antonio homes and what you can do to fix them.
1. Dirty or Clogged Air Filters
One of the simplest yet most overlooked HVAC issues is a dirty air filter. Over time, dust, pet dander, and debris accumulate in your filter, restricting airflow and forcing your system to work harder. This can lead to reduced efficiency, higher energy bills, and even system failure if left unchecked.
How to Fix It:
- Check your air filters every month and replace them every 1–3 months, depending on usage.
- If you have pets or allergies, consider upgrading to a high-efficiency filter to improve indoor air quality.
- Regular filter changes can extend the lifespan of your HVAC system and keep your home’s air cleaner.
2. Refrigerant Leaks
Your AC system relies on refrigerant to cool your home. When refrigerant levels are low due to leaks, your system won’t be able to cool efficiently, leading to higher energy costs and poor performance. If left unaddressed, a refrigerant leak can cause serious damage to your compressor.
How to Fix It:
- If your AC isn’t cooling properly, contact a professional for an inspection.
- A technician can locate the leak, repair it, and recharge your refrigerant to manufacturer-recommended levels.
- Routine spring HVAC maintenance can help catch refrigerant leaks early.
3. Uneven Heating or Cooling
If some rooms in your home are colder or hotter than others, it’s often due to issues with your HVAC system’s airflow or insulation. Poorly designed ductwork, blocked vents, or even an aging system can contribute to temperature imbalances.
How to Fix It:
- Make sure all air vents are open and unblocked by furniture or curtains.
- Check for leaks in your ductwork and have them sealed if necessary.
- Upgrade to a zoning system or a smart thermostat for more even temperature control.
- A professional HVAC inspection can determine if your system needs an adjustment or replacement.
4. Thermostat Issues
Your thermostat acts as the brain of your HVAC system, but if it’s malfunctioning, it can cause heating and cooling problems. Incorrect thermostat settings, dead batteries, or outdated models can lead to inconsistent indoor temperatures.
How to Fix It:
- Check the thermostat’s batteries and replace them if needed.
- Ensure the thermostat is set to the correct mode (cooling in summer, heating in winter).
- If you have an older thermostat, consider upgrading to a programmable or smart thermostat for better control over your home’s temperature.
5. HVAC System Short Cycling
Short cycling occurs when your HVAC system turns on and off frequently without completing a full cycle. This can be caused by dirty air filters, an oversized system, low refrigerant, or a faulty thermostat. Short cycling increases wear and tear on your system and leads to higher energy bills.
How to Fix It:
- Replace dirty air filters to ensure proper airflow.
- Have an HVAC professional check for refrigerant leaks or electrical issues.
- If your system is too large for your home, you may need a properly sized replacement.
- Scheduling regular AC repair and maintenance can prevent short cycling from becoming a major issue.
