Our HVAC systems in New Jersey pull serious duty in every season. That means that even the best systems experience common HVAC problems over time.
Dustin’s Plumbing Heating and A/C Repair is the leading provider of expert heating and air conditioning services in Jackson, New Jersey, and we’d like to share some insights on the issues we run into most often.
1. Dirty or Clogged Air Filters
Every HVAC system relies on unrestricted airflow to work correctly. As your air filter traps dust, dirt, and allergens, it becomes clogged, forcing your system to work harder. This not only drives up your energy bills but can also cause breakdowns.
The symptoms to watch for include:
- Weak airflow from vents
- Increased dust around your home
- Higher utility costs
- Short cycling (system turning on and off frequently)
First, turn off the HVAC system, remove the old filter, and replace it with a new one. Most homes require replacement every one to three months, especially if you have pets or allergies.
If replacing the filter doesn’t improve performance, debris may be in your ductwork or other components. Call your local HVAC expert for help.
2. Thermostat Malfunctions
Your HVAC system will likely not heat or cool as expected if your thermostat is not sending accurate signals. This is often caused by dead batteries, incorrect settings, or wiring issues.
The symptoms to watch for with these common HVAC problems include:
- System is not responding to temperature changes
- Inconsistent indoor temperatures
- Blank or unresponsive thermostat display
Replace the batteries, check the temperature settings, and make sure the thermostat is set to the correct mode (heat or cool). For older models, ensure it’s level and calibrated.
If your thermostat is hardwired, has complex wiring issues, or still isn’t working after basic troubleshooting, it’s time for professional help.
3. Refrigerant Leaks
Your system relies on chemical refrigerants to cool your home. Leaks reduce cooling efficiency and can cause serious damage to your compressor if ignored.
The symptoms to watch for include:
- Warm air blowing from vents despite the system running
- Hissing or bubbling sounds near the outdoor unit
- Ice buildup on refrigerant lines or coils
- Rising energy bills
There’s no appropriate DIY fix in this situation. Handling refrigerant requires specialized tools and EPA certification. Your local licensed technician can locate and repair the leak, then recharge your system to factory specifications.
4. Poor Airflow
If some rooms in your Jackson home feel stuffy while others are comfortable, your system may have airflow problems. The causes range from blocked vents and duct leaks to blower motor issues.
The symptoms to watch for include:
- Weak or uneven airflow from vents
- Hot and cold spots throughout your home
- Your system runs longer than usual
Replace the air filter if it is dirty. Make sure vents are open and unobstructed by furniture or rugs. Check accessible ducts for visible disconnections or damage caused by these common HVAC problems.
If airflow problems persist after basic fixes, you may have a blower motor or ductwork issue that needs expert attention.
5. Frozen or Dirty Evaporator Coils
The evaporator coils absorb heat from indoor air. Over time, they can become frozen or dirty because of restricted airflow or low refrigerant levels.
The symptoms to watch for include:
- Ice on coils or refrigerant lines
- Warm air from vents despite the cooling mode being on
- Water puddles around the indoor unit as ice melts
Turn off your system and allow the coils to thaw. Replace dirty air filters and ensure vents are unobstructed. If freezing returns quickly after you restart the unit, you may have low refrigerant or severe coil contamination requiring professional cleaning.
6. Blower Motor Failures
The blower motor powers the fan that circulates air through your system. Its failure brings airflow to a complete stop.
The symptoms to watch for include:
- No airflow from vents
- Grinding, squealing, or rattling noises
- Burning smell when the system runs
- Overheating or frequent shutdowns
Replace or clean the air filter, and check for visible obstructions in the blower wheel (with the power off). If the motor isn’t running after basic checks, call your qualified technician for repairs or replacements.
