How to Troubleshoot Your Heat Pump in New Lenox, IL: Common Issues and Solutions

A heat pump is an energy-efficient way to heat and cool your home year-round, making it an increasingly popular choice for homeowners looking to cut energy costs without sacrificing comfort. Because heat pumps work by transferring heat rather than generating it, they can be up to three times more efficient than traditional HVAC systems. 

Our experienced technicians specialize in diagnosing and repairing heat pump issues quickly and effectively. We’ve been serving the New Lenox community for years, and we understand the unique challenges local homeowners face with their HVAC systems throughout the Midwest’s changing seasons.

So whether it’s a minor fix or a more complex repair, you can trust Zark Heating & Cooling to restore your comfort with honest service, expert knowledge, and affordable solutions.

Heat Pump Not Turning On

If your system won’t start at all, the issue could be as simple as a tripped circuit breaker or a thermostat setting.

Troubleshooting Tips:

• Check your thermostat to ensure it’s set to “heat” or “cool” as needed and that the temperature is properly set.

• Inspect your circuit breaker panel for any tripped breakers. Reset if necessary.

• Make sure the registers are open and unobstructed to allow proper airflow.

If you hear a clicking sound but the unit doesn’t start, the starter capacitor may be faulty and require professional replacement.

Blowing Cold Air in Heat Mode

A common concern during Illinois winters is a heat pump that seems to blow cold or lukewarm air.

Possible Causes:

• The thermostat may be set incorrectly; ensure it’s in “heat” mode.

• A dirty air filter can restrict airflow and reduce heating efficiency.

• Low refrigerant levels can prevent the system from heating properly.

• The outdoor unit might be dirty or obstructed, hindering heat absorption.

Pro Tip: Sometimes, the air from a heat pump feels cooler than expected because it’s closer to room temperature, even though it’s still warming your home effectively.

Frozen Outdoor Unit

In cold climates like New Lenox, it’s normal for the outdoor unit to develop frost. However, if it becomes encased in ice and doesn’t defrost, there may be a problem.

What to Check:

• Ensure the defrost cycle is functioning; a malfunction could indicate faulty sensors or control boards.

• Low refrigerant levels can also lead to freezing issues.

• Check for debris or obstructions around the outdoor unit that might impede airflow.

Short Cycling

If your heat pump turns on and off frequently, it may be short cycling, which can reduce efficiency and increase wear.

Potential Causes:

• An oversized system can heat or cool the space too quickly, leading to frequent cycling.

• Thermostat issues or placement near heat sources can cause incorrect temperature readings.

• Dirty filters or coils can lead to overheating and shutdowns.

Unusual Noises

Strange sounds like grinding, squealing, or rattling can indicate mechanical problems.

Listen For:

• Grinding noises may suggest motor bearing issues.

• Squealing could point to belt problems.

• Rattling might mean loose components or debris in the unit.

If you hear unusual noises, it’s best to have a professional inspect the system to prevent further damage.
