Is Something Wrong? 10 Signs It’s Time for HVAC Repair

Your HVAC system is responsible for keeping your home livable in every season, but even the most durable systems encounter issues periodically. Detect these problems early to save you from expensive repairs or the need for a full replacement. Here are 10 signs that you should schedule HVAC repair without delay.

1: More Expensive Energy Bills

An abrupt surge in energy costs even though there’s not a similar shift in usage strongly indicates that your HVAC system is not running properly. Common causes include aging equipment, leaks in the ductwork or dirty coils, forcing your system to work longer and harder to sustain your preferred temperature. Jumping energy bills are often an early sign your system needs repair, so it’s crucial to watch for unexplained cost increases.

2: Louder Noises

Your HVAC system should work smoothly, but if you are noticing unfamiliar banging sounds, it’s likely something’s wrong. Loud and annoying noises often point to unsecured parts, deteriorated belts or a failing motor. Neglecting these sounds could lead to greater damage, so try to reach out to a professional for furnace or AC repair as soon as you hear them.

3: Foul Odors

When your HVAC system is giving off strange odors, it’s time to check it out. Stale smells indicate mold in your ductwork or HVAC system, while smoky odors indicate electrical damage or overheating components. These odors stop your home from smelling clean, and in severe cases can even impact your health. A certified HVAC technician can pinpoint and fix the issue to restore clean-smelling operation.

4: Weak Airflow

If the air coming from the air ducts feels like it’s gotten worse or inconsistent, a few possible issues might be to blame. The blower’s air filter may be obstructed by debris, part of the air ducts may be disconnected or the air blower may be wearing out. Not only will weak airflow make your home more uncomfortable, it also forces your system to run inefficiently, leading to escalating energy bills and excessive wear and tear.

5: Lukewarm Air

Perhaps the airflow is normal, but the temperature is unusually mild compared to the settings. When turning on your air conditioner, warmer “cooling” often points to low refrigerant or a faulty compressor. On the heating side, a lack of hot air can be caused by a broken ignition system or issues with the ignitor. Resolving the fundamental problem is the only way to restore home comfort.

6: Changing Temperatures

When one room feels like you’re in the furnace while another is more like your refrigerator, it’s likely your HVAC system is struggling to circulate air evenly. This issue could be caused by leaky air ducts, a malfunctioning thermostat or even the system itself losing efficiency. Inconsistent temperatures will obviously lower comfort and can also increase energy costs and require repairs.

7: Excessive Heating or Cooling Cycles

Your HVAC system should have normal operating cycles. If it repeatedly shuts back off shortly after just beginning a cycle, the system is not performing how it is supposed to. This issue, known as short cycling, is often caused by a faulty thermostat, a blocked air filter or an over- or undersized system. Fixing this problem earlier avoids wear and tear that could contribute to a premature HVAC replacement.

8: Humidity Is Too High or Low

Your HVAC system plays a significant role in managing indoor humidity levels. If you experience unusually elevated humidity or dryness, the HVAC system may not be performing properly. High humidity levels are often gross and can encourage mold growth, while reduced humidity leads to cracked skin and nasal irritation. Problems like a malfunctioning compressor or a blocked drain line may prevent your system from managing humidity correctly. Luckily, these situations are easily addressed.

9: Water Is Pooling Nearby

Water leaking or standing along your HVAC system is a clear sign of problems. This may have started with a backed-up condensate drain line, which prevents moisture from moving through the lines properly, or ice forming on the evaporator coils and slowly breaking down. Whatever the cause, contact a professional to patch up any leaks as soon as you see them to reduce property damage and more severe issues.

10: A Malfunctioning Thermostat

Is your HVAC system not functioning correctly to your thermostat inputs? For instance, the system may not start up when you modify the temperature, or it may frequently misread commands. Whether the issue stems from the thermostat itself or its relationship with the HVAC system, these concerns cause lack of efficiency and temperature control problems.
