When Your Heat Pump Stops Working: Understanding the Problem
A heat pump not working in Greenwood, IN, can quickly turn a comfortable home uncomfortable. When winter temperatures drop below freezing or summer heat climbs, a malfunctioning heat pump means losing the year-round comfort you depend on.
Quick Fixes to Try First:
- Check your thermostat – Verify it’s set to the correct mode (heat or cool) and temperature.
- Inspect the circuit breaker – Reset any tripped breakers for your HVAC system.
- Replace your air filter – A clogged filter blocks airflow and prevents proper operation.
- Clear the outdoor unit – Remove leaves, snow, ice, or debris blocking the condenser.
- Verify power switches – Ensure both indoor and outdoor disconnect switches are “on.”
If you’re experiencing warning signs your heat pump needs professional service, or these simple checks don’t solve the problem, contact Star Heating, Cooling & Plumbing for expert heat pump repair.
Heat pumps are complex, efficient systems for both heating and cooling. Various components can fail, from refrigerant leaks and compressor issues to defrost cycle problems and electrical malfunctions. Understanding what might be wrong helps you decide between a DIY fix and calling a professional.
Is Your Heat Pump Trying to Tell You Something? Key Warning Signs
Your heat pump signals problems through its behavior. Learning to recognize these signs early can prevent major issues, especially in Greenwood, IN,‘s varied climate, ensuring year-round comfort.
The most obvious sign is that your home just isn’t comfortable anymore. If your house can’t reach the set temperature, or it blows cool air in heat mode (or vice versa), the heat pump is struggling. This could indicate low refrigerant or a failing compressor.
Strange sounds are your heat pump’s cry for help. A healthy system hums quietly. Hissing or gurgling often points to a refrigerant leak. Loud clanking or banging can mean compressor issues or loose parts. A persistent click might be a bad starter capacitor.
A sudden spike in energy costs means your heat pump is working overtime. Lost efficiency forces it to run longer, increasing bills. A significant jump could signal a clogged filter, refrigerant leak, or defrost issues.
Constant cycling (short cycling), where the unit turns on and off every few minutes, causes excessive wear. Common culprits include an oversized unit, dirty filters, or refrigerant leaks. Our blog on why your heat pump turns on and off frequently digs deeper into this frustrating issue.
Weak airflow leads to uneven temperatures. If air barely moves from your vents, you may have blocked vents, a dirty filter, blower motor issues, or leaky ducts.
Ice buildup can be tricky. A little frost on the outdoor unit in winter is normal and handled by the defrost cycle. However, excessive ice on the coils points to trouble, like low refrigerant, dirty coils, or a malfunctioning defrost cycle.
Spotting these key warning signs your heat pump needs professional service helps you act before problems worsen. When your heat pump not working in Greenwood, IN, shows these symptoms, a quick call to Star Heating, Cooling & Plumbing can prevent a breakdown.

Why Is My Heat Pump Not Working in Greenwood, IN? Common Causes & DIY Checks
When your heat pump not working in Greenwood, IN, it’s a major disruption. The good news is that not every issue requires a professional repair. Let’s review common causes and what you can check yourself.
Here are some of the usual suspects when a heat pump isn’t performing:
- Power Loss: It’s a common issue. Both indoor and outdoor units need power. A tripped breaker or an accidentally flipped power switch can stop the system. Always check your electrical panel first.
- Thermostat Errors: The thermostat controls your system. Incorrect settings (e.g., “cool” instead of “heat”), dead batteries, or bad programming can make it seem like the heat pump is broken.
- Clogged Filters: A clogged air filter restricts airflow, forcing your system to work harder, lose efficiency, and potentially freeze up. This is a major cause of problems, so regular filter changes are crucial. Our guide on How to Clean a Heat Pump has some great tips.
- Obstructed Outdoor Unit: The outdoor unit needs clear space to work. Snow, ice, leaves, or dirt can block it, hindering heat transfer and efficiency, especially in winter.

Simple DIY checks for a heat pump not working in Greenwood, IN
Before calling for service, try these simple DIY checks for a heat pump not working in Greenwood, IN. They often resolve common issues quickly.
- Check thermostat settings: Ensure it’s on the correct mode (heat/cool) and temperature. Set the fan to “auto” for best efficiency.
- Inspect circuit breakers: Check your electrical panel for tripped breakers labeled for your HVAC system. If a breaker is tripped, flip it completely off and then back on.
- Clean or replace air filter: Pull out the filter. If you can’t see light through it, replace it. A clean filter dramatically improves airflow.
- Clear debris from outdoor unit: Ensure the unit is clear of leaves, snow, ice, and dirt, with at least two feet of clearance around it. Let ice melt naturally; don’t chip it off.
If your heat pump is still acting up, especially with frequent cycling, it could signal a deeper issue. We dive into that in our article: Why is my heat pump turning on and off frequently?
When DIY fixes aren’t enough for a heat pump not working in Greenwood, IN
Some problems are too complex or risky for DIY fixes and require a professional.
- Persistent Issues: If basic troubleshooting fails, it’s a sign of a deeper mechanical or electrical problem that needs a professional diagnosis.
- Electrical Problems: Issues beyond a tripped breaker, like faulty wiring or capacitors, are dangerous. Leave these to trained technicians for safety.
- Refrigerant Concerns: Hissing sounds, ice on coils, or poor performance can indicate a refrigerant leak. This chemical requires professional handling to find and fix the leak safely. Low refrigerant can cause severe damage.
When these more intricate issues pop up, our friendly team at Star Heating, Cooling & Plumbing is ready to help. We offer expert Heat Pump Repair Services to get your home comfortable again.
When to Call a Professional: Complex Heat Pump Problems
While some fixes are simple, many heat pump problems require a professional. In Greenwood’s climate, knowing when to call for help prevents discomfort and costly damage. The following issues are too complex for a DIY approach and demand an expert’s attention.
Refrigerant leaks require professional service. Refrigerant is essential for heat transfer, and a leak reduces efficiency, increases energy bills, and can damage your system. Compressor failure is a critical and expensive issue. As the heart of the system, a failed compressor stops all heating and cooling. Defrost cycle issues are common in Indiana winters. If the defrost cycle malfunctions, thick ice can form on the outdoor unit, crippling its ability to heat your home. Finally, electrical malfunctions beyond a tripped breaker are dangerous. Issues with components like the reversing valve, fan motors, or capacitors need specialized tools to diagnose and repair safely.

Signs of a Refrigerant Leak
Low refrigerant means there’s a leak. This is a serious problem requiring immediate professional attention to protect your system.
- Hissing or gurgling sounds often indicate refrigerant escaping from a leak in the lines.
- Ice on coils is a key sign of low refrigerant, as the system can’t transfer heat correctly, causing moisture to freeze on the indoor or outdoor coils.
- Reduced performance is a common symptom. The system runs constantly but can’t reach the set temperature, blowing lukewarm air.
If you notice these signs, call a professional immediately. A refrigerant leak strains the compressor and can lead to its complete failure—a much more expensive repair. Our guide on Discover Solutions To Heat Pump Not Heating or Cooling or Heat Pump Blowing Cold Air provides additional troubleshooting information.
Symptoms of Compressor Failure
The compressor is the most expensive component in your heat pump. Its failure can mean a system replacement, but it usually provides warning signs first.
- Loud clanking or banging from the outdoor unit suggests internal mechanical failure in the compressor.
- Unit fails to start, though you may hear a click or hum, can be caused by seized components or an electrical problem.
- Frequent breaker trips are a safety warning that the compressor is drawing too much power. Call a professional immediately.
- No heating or cooling occurs when the compressor fails completely. The indoor fan may blow, but the air won’t be conditioned.
Compressor issues require immediate professional diagnosis and repair. Our comprehensive Heat Pump Services include everything from troubleshooting to complete compressor replacement when necessary.
Defrost Cycle Problems in Indiana’s Climate
Greenwood’s cold winters challenge heat pumps. As a heat pump works, frost normally forms on the outdoor coil. The defrost cycle melts this by briefly reversing the system. Problems with this cycle are common in our climate.
- Excessive ice buildup means the defrost cycle is failing. A thick layer of ice covering the outdoor unit will insulate it and drastically reduce efficiency.
- Unit stuck in defrost mode can cause cold air to blow from vents and forces the expensive auxiliary heat to run constantly.
- Reduced winter efficiency is the result. The system runs longer, your home feels cold, and energy bills spike.
Causes for defrost problems include a faulty control board, sensor, or reversing valve. These are not DIY fixes and require professional diagnosis.

Frequently Asked Questions about Heat Pump Issues
When your heat pump not working in Greenwood, IN, we know you need answers fast. Here are some of the most common questions we hear from homeowners.
Why is my heat pump blowing cold air when it’s set to heat?
Feeling cold air in heat mode is unsettling, but there are a few common reasons.
The defrost cycle is a common cause. To melt normal frost buildup on the outdoor unit, your system briefly reverses. During this 5-15 minute cycle, the indoor fan may blow unheated air, which feels cool. This is normal operation.
However, if the cold air persists, you may have low refrigerant levels. A leak prevents the system from moving heat effectively, resulting in cool air. Another possibility is a stuck reversing valve, which can get stuck in cooling mode. If the cold air persists or you notice other symptoms, it’s time to call a professional. Our article on Is a Heat Pump More Effective at Cooling or Heating? offers additional insights.
How can I tell if my heat pump is effective in cold weather?
Many homeowners wonder about heat pump performance in cold weather. Modern heat pumps are very effective in Indiana’s climate.
- Watch for supplemental heat. It’s normal for auxiliary heat to kick in when temperatures drop below 35-40°F. However, if it runs constantly, your heat pump may be undersized or have a mechanical problem.
- Notice your home’s comfort level. An effective heat pump maintains a consistent temperature. If it runs constantly without warming the house, or if there are cold spots, it’s not performing correctly.
- Proper sizing is crucial. An undersized unit will struggle in extreme cold. Professional installation ensures correct sizing for optimal performance.
