When you schedule an HVAC repair, you might be expecting a straightforward fix, such as a faulty blower motor or a refrigerant recharge. However, there are times when repairs reveal unexpected underlying issues that you may not have been aware of. In this blog, we’ll explore five common yet often surprising issues that HVAC repairs can uncover and why addressing them early can save you time and money in the long run.
1. Ductwork Problems
Hidden Issues in Your Ducts:
When your HVAC system isn’t functioning as expected, one possible culprit could be the ductwork. Leaky or damaged ducts can significantly reduce your system’s efficiency, forcing your HVAC unit to work harder. During a repair, your technician may discover gaps, cracks, or other problems with the ducts that are hindering airflow.
What This Might Mean:
- Increased energy costs: Leaky ducts can lead to up to 30% of your heated or cooled air being wasted.
- Uneven temperatures: You might notice that certain rooms in your home are hotter or colder than others due to poor airflow.
What to Do:
Schedule duct inspection: If your technician identifies ductwork issues, it’s important to address them quickly to avoid further inefficiency and system strain.
2. Faulty Thermostat Wiring
Wiring Issues Can Disrupt Temperature Control:
If your HVAC system isn’t responding properly to thermostat commands, the problem might not be the system itself, but faulty wiring behind your thermostat. During repairs, technicians may uncover outdated or frayed wiring that’s causing your system to malfunction.
What This Might Mean:
- Temperature fluctuations: A malfunctioning thermostat wiring can result in inconsistent temperatures throughout the home.
- System failure to turn on/off: Incorrect wiring could prevent the HVAC unit from responding when you change the temperature on your thermostat.
What to Do:
Replace faulty wiring: If wiring issues are found, ensure that they are repaired or replaced to restore full system functionality.
3. Refrigerant Leaks
Refrigerant Loss Reduces Cooling Efficiency:
When your technician identifies a refrigerant leak during an HVAC repair, it’s often an unexpected finding. Refrigerant is essential for the cooling process in your AC system, and leaks can lead to inefficient cooling and potential system damage.
What This Might Mean:
- Ineffective cooling: Low refrigerant levels can result in your AC system not cooling effectively, even when it’s running.
- Risk of compressor damage: Operating an AC unit with low refrigerant can damage the compressor, a costly repair.
What to Do:
Seal the leak: Ensure that the leak is located and sealed, and that the refrigerant levels are properly topped off to restore your system’s cooling capacity.
4. Mold and Mildew in the System
Mold and Mildew Can Grow in Damp HVAC Components:
If your HVAC system has been exposed to excess moisture, it could become a breeding ground for mold and mildew. During a routine repair, your technician may discover these contaminants lurking in the evaporator coils, ducts, or filters. This issue not only affects air quality but can also contribute to system inefficiency.
What This Might Mean:
- Poor indoor air quality: Mold and mildew spores can circulate through your home, leading to respiratory issues, allergies, and overall poor indoor air quality.
- Foul odors: You may notice musty odors coming from your vents when the system is running.
What to Do:
Professional cleaning: Have your technician perform a thorough cleaning of your system to remove mold and mildew, and replace any contaminated parts, such as filters.
5. Outdated or Undersized HVAC System
Age and Size Matter for HVAC Efficiency:
During a repair, your technician might point out that your HVAC system is outdated or undersized for your home’s heating and cooling needs. An older system may require more frequent repairs, while an undersized unit can struggle to maintain temperature, leading to more wear and tear.
What This Might Mean:
- Frequent breakdowns: Older systems are more likely to experience mechanical failures, requiring more repairs.
- Inefficient cooling or heating: An undersized unit has to work harder to achieve the desired temperature, leading to higher energy bills and premature system failure.
What to Do:
Consider system replacement: If your HVAC system is outdated or too small, consider replacing it with a more efficient unit that suits your home’s needs. Your technician can help with proper sizing and recommendations.
