Your heat pump works hard year-round—switching between heating and cooling, responding to outdoor conditions, and adjusting to your thermostat settings. That kind of use means there are plenty of opportunities for problems to pop up.

If you’re dealing with any of these issues, here’s what could be happening—and how we can fix them:

It’s Running, But the Air Isn’t the Right Temperature

When your heat pump is blowing air, but your home still feels too warm or too cold, it could point to a few common issues.

Faulty Reversing Valve

If your system won’t switch between heating mode and cooling mode, a faulty reversing valve is often the cause. You might get warm air when trying to cool, or cool air when trying to heat. We’ll test the valve and replace it if needed to restore normal operation.

Refrigerant Leak

Low refrigerant can prevent your system from reaching your desired temperature, even if everything else seems to be working. You might hear hissing or notice ice on the lines. We’ll locate the refrigerant leak, repair it, and recharge the system so it can run at full strength again.

The Thermostat Is Set—But Nothing’s Happening

If your system seems unresponsive or is turning off and on at odd times, the problem may be in the controls.

Malfunctioning Thermostat

A failing thermostat can cause inaccurate readings or unresponsive settings. If the room feels too hot or too cold, or your system isn’t following commands, we’ll test your thermostat, recalibrate it, or replace it with a newer, more reliable model.

Electrical or Sensor Failures

Your HVAC system relies on capacitors, sensors, and control boards to run properly. If your heat pump won’t turn on at all—or it keeps shutting off—it may be one of these components. We’ll do a thorough inspection, pinpoint the failure, and safely replace what’s needed.

The System Is Frozen or Iced Over

If your outdoor unit or indoor coil is covered in frost or ice, that’s a red flag—and it needs to be fixed fast.

Frozen Coils

Ice buildup on your coils means your system is struggling with airflow or refrigerant levels. This can lead to poor performance or a complete shutdown. We’ll carefully defrost the coils, clean them, and check for any airflow or refrigerant issues so your cooling system and heating system stay protected.

It’s Making Loud or Unusual Noises

If your heat pump has suddenly gotten noisy, don’t ignore it—unusual sounds are often the first sign of a mechanical problem.

Parts Wearing Out

Rattling, buzzing, or grinding could mean loose parts, worn motors, or even compressor trouble. Left unchecked, these can lead to more costly repairs. We’ll identify the source and resolve it before it gets worse, saving you time and money.No matter the make or model, we repair air source heat pumps and ductless mini split systems—even if we didn’t install them. Schedule your heat pump repair in Mason, OH, with our experienced team today.

Every system reaches the point where repairs just aren’t cutting it anymore. If your existing system is constantly acting up, struggling to keep your home comfortable, or draining your wallet with repair after repair, it might be time for a change.

At Hill-Air Heating & Air Conditioning, we’re here to help you figure out what makes the most sense. We’ll perform a complete system diagnostic, check your unit’s condition, and walk you through the pros and cons of repair vs. replacement. If a new unit is the better option, we’ll guide you through the heat pump installation process, explain available financing, and help you take advantage of any rebates or tax incentives.

Here’s what we’ll discuss when you have an older heat pump or are facing heavy damage or frequent repairs:

Repairs Are Worth It When:

• Your Heat Pump Is Under 10 Years Old: If your system is still relatively new and has been cared for, it probably has a lot of life left. Newer heat pumps are designed for long-term use—don’t replace them before you have to.
• You’ve Only Had a Few Minor Issues: A one-time thermostat issue, clogged filter, or a small part replacement isn’t cause for alarm. Small hiccups don’t mean the whole system is failing.
• You’ve Kept Up With Regular Maintenance: If you’ve stayed on top of annual tune-ups, your system is more likely to recover from the occasional issue. Maintenance really does pay off in longevity and performance.

Consider Replacing Your Heat Pump When:

• The System Is 12–15+ Years Old: Even the best systems wear down with time. If yours is older, losing efficiency, or just not keeping up like it used to, it may be time to talk about a replacement.
• Repairs Are Becoming Frequent or Expensive: If it feels like you’re calling for service every season—or the next fix is going to cost several hundred dollars—it might be smarter to put that money toward a new system.
• It’s Getting More Expensive to Maintain: Older systems lose efficiency, and that shows up in your energy bills. If your monthly costs are creeping up with no change in usage, your system could be to blame.

We’ll never try to sell you something you don’t need. If a heat pump repair will keep your system going and save you money, we’ll do that. If a heat pump replacement is the smarter long-term option, we’ll help you choose the right one and support you through every step of the process.

When you first bought your heat pump, hopefully someone explained how important regular maintenance is. If you got your system from us, we definitely talked to you about it—and probably shared the details of our heat pump maintenance services too.

We know maintenance can seem like just another thing to pay for, but it truly makes a huge difference. In fact, regular maintenance has been shown to reduce the risk of major repairs by up to 95% and can extend the life of your HVAC system by 10–15 years. That’s peace of mind you can feel all year long.

The Best Time to Schedule Heat Pump Tune-Ups

The ideal time to service your heat pump is before it hits heavy use—spring for cooling and fall for heating. These seasonal checkups help catch small issues before they become major ones. By tuning up your system ahead of extreme weather, you’re giving it the best chance to run without breaking down. Here’s what we’ll do during your heat pump tune-up:

• Clean indoor and outdoor coils to improve airflow and help your system run more efficiently.
• Check refrigerant levels and look for leaks so your system heats and cools without overworking.
• Inspect electrical parts to prevent safety issues or sudden breakdowns.
• Test thermostat settings and system controls to keep your home at the right temperature.
• Lubricate moving parts to reduce wear and help motors last longer.
• Make sure the system switches properly between heating and cooling modes.
• Review overall system performance to catch issues early and keep your HVAC system running smoothly.

Are heat pumps expensive to fix?

Most heat pump repairs are pretty reasonable, especially if the issue is caught early. The cost really depends on what’s wrong, but we’ll always explain the problem clearly and go over pricing before we do anything, so there are no surprises.

How much does a heat pump repair cost?

The price depends on the type of repair. Something simple like a thermostat or capacitor might be a few hundred dollars. Larger repairs like a compressor will cost more, but we’ll talk through your options and help you decide what makes the most sense.

Will the age of my heat pump affect the cost of repairs?

Yes, it can. Older systems sometimes need parts that are harder to find, or you might be dealing with multiple issues at once. If we think a repair won’t hold up long-term, we’ll let you know and help you weigh the pros and cons of heat pump repair vs. heat pump replacement.

Are any parts of my heat pump covered under warranty?

They might be, especially if your system is newer. Many manufacturers cover major parts like the compressor, reversing valve, or coils. We’ll check the warranty for you and help handle the paperwork if a part is eligible for coverage.

How long do heat pump repairs usually take?

Most repairs can be done the same day, especially if we have the parts on hand. If something needs to be ordered, we’ll let you know right away and schedule a return visit as soon as it arrives.

If your heat pump isn’t working—or it’s just performing like it once was—it can make your home very uncomfortable very quickly. And when it’s really hot or cold outside, that’s not just frustrating—it can be risky for your health and safety. At Hill-Air Heating & Air Conditioning, we make it easy to restore your heat pump’s performance. Our team will find the problem, fix it the right way, and help you feel good in your home again.
