What Went Wrong? 10 Signs It’s Time for HVAC Repair

Your HVAC system is responsible for keeping your home cozy in every season, but even the most reliable systems encounter issues every so often. Spot these problems early to reduce the risk of expensive repairs or the need for a full replacement. Here are 10 signs that you should book HVAC repair without delay.

1: More Expensive Monthly Bills

A sudden jump in energy costs even though there’s not a similar shift in usage is a sign that your HVAC system is not running properly. Common culprits include old equipment, leaks in the air ducts or dirty coils, forcing the HVAC system to work longer and harder to sustain your preferred temperature. Jumping energy bills are often among the first signs your system needs repair, so it’s important to monitor for any unexplained bill increases.

2: Loud or Annoying Noises

Your HVAC system should run without making too much noise, but once you are noticing unfamiliar banging sounds, it may be because something’s wrong. Loud and annoying noises often suggest loose parts, worn-out belts or a failing motor. Ignoring these sounds can lead to additional damage, so try to call a professional for furnace or AC repair as soon as you become aware of them.

3: Weird Odors

When your HVAC system gives off odd odors, it’s time to find out why. Stale smells are a sign of mold in your ductwork or HVAC system, while burning/waxy odors suggest electrical damage or overheated components. These odors keep your home from smelling inviting, and in severe cases may even mess with your health. A professional HVAC technician can identify and correct the issue to restore no-smell operation.

4: Weaker Airflow

If the airflow coming from the air ducts feels weak or erratic, several possible issues may be to blame. The filter may be blocked, part of the air ducts may be disconnected or the circulation motor may be malfunctioning. Not only can weak airflow make your home less comfortable, it also forces your system to exert more effort, leading to increased energy bills and additional wear and tear.

5: Lukewarm Air

Sometimes the airflow is consistent, but the temperature is unusually mild compared to your thermostat. When running your air conditioner, warmer “cooling” often points to low refrigerant or a defective compressor. On the heating side, a lack of hot air may be caused by a defective ignition system or a problem with the ignition system. Addressing the underlying problem is the only way to restore home comfort.

6: Erratic Temperatures

When one part of the house feels like one big heater while another room’s temperature is like a freezer, it’s likely your HVAC system is struggling to circulate air evenly. This issue could originate from a break in the ventilation system, a malfunctioning thermostat or even the system itself losing efficiency. Inconsistent temperatures will obviously lower comfort and can also elevate energy costs and require repairs.

7: Excessive Starting and Stopping

Your HVAC system should have consistent heating or cooling cycles. If it repeatedly shuts back off shortly after just starting up, the system is not performing how it needs to. This specific malfunction, known as short cycling, is often caused by thermostat problems, an obstructed air filter or a mismatched system. Addressing this problem earlier avoids wear and tear that could result in equally early HVAC replacement.

8: Humidity Is Too High or Low

Your HVAC system plays a big role in managing indoor humidity levels. If you experience unusually elevated humidity or dryness, your system may not be performing properly. Increased humidity levels are difficult to live with and can promote mold growth, while lower humidity leads to cracked skin and nasal irritation. Root causes like a broken compressor or a moldy drain line may stop your system from regulating humidity properly. Fortunately, these issues are easily addressed.

9: Water Leaks Close By

Water gathering near your HVAC system is a known sign of problems. This could be caused by a blocked condensate drain line, which prevents moisture from clearing properly, or ice forming on the condenser coils and slowly breaking down. Regardless of the cause, contact a professional to fix leaks as soon as you see them to prevent property damage and more severe issues.

10: A Broken Thermostat

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