A heat pump that isn’t working properly can be stressful, but sometimes the solution is easier than you think. Before calling for a professional heat pump repair, try these quick troubleshooting steps. At Hill-Air Heating & Air Conditioning, we believe in helping homeowners stay informed, so here’s what to check before scheduling a heat pump service call.

• Check the Thermostat: Make sure it’s set to the correct mode (heat or cool) and that the temperature is where you need it. If your thermostat runs on batteries, replace them.
• Inspect the Air Filter: A dirty air filter can restrict airflow, making your heat pump system work harder or even shut down. If your filter is clogged, swap it out for a clean one.
• Reset the Circuit Breaker: If your heat pump isn’t turning on at all, check your electrical panel for a tripped breaker and reset it if necessary.
• Look for Ice Buildup: If you see ice on the coils, turn off your heat pump and let it thaw. If the problem keeps happening, there could be an issue with the defrost cycle.

Trust the Heat Pump Repair Experts at Hill-Air

If troubleshooting hasn’t solved the issue, professional service is the next step. Many heat pump repairs require specialized tools, expert diagnostics, and proper handling to ensure a safe, lasting fix.

Your heat pump system depends on complex components like refrigerant lines, compressors, and electrical circuits—attempting a DIY repair or hiring an inexperienced contractor can lead to further damage, higher costs, or even a voided warranty.

At Hill-Air Heating & Air Conditioning, our team is licensed and insured, meaning your repair is handled by qualified professionals who meet industry standards for safety and reliability. We use factory-authorized parts and follow manufacturer guidelines to protect your warranty and keep your system running efficiently.Schedule your heat pump repair with us today and get expert service you can count on.

We’ve seen it all when it comes to heat pump repairs. Our heat pump technicians are trained to work on all major brands, and we specialize in air source heat pump repair and ductless mini split repairs. If something’s off with your system, let us know what’s happening—poor airflow, high energy bills, ice buildup, or inconsistent temperatures. The more details you share, the faster we can diagnose and fix the issue.

Why Is My Energy Bill So High?

If your energy costs have skyrocketed, but your heat pump system doesn’t seem to be doing anything different, it’s a red flag. Your system might be overworking due to a refrigerant leak, a dirty filter, or a struggling compressor. Our team will perform an energy efficiency assessment, inspect key components, and make any necessary repairs to get your bills back under control.

Why Is My Heat Pump Blowing Cold Air in Heat Mode?

A heat pump that’s supposed to warm your home but is only pushing out cold air can be incredibly frustrating. This could be caused by a malfunctioning thermostat, a refrigerant issue, or a problem with the reversing valve (the part that switches between heating and cooling). We’ll run a full system diagnostic, check for any faulty components, and get your system back to heating properly.

Why Does My Heat Pump Keep Turning On and Off?

Frequent cycling—when your heat pump turns on and off too often—can be caused by a dirty air filter, an oversized unit, or a malfunctioning thermostat. This problem not only reduces your home’s comfort but also puts unnecessary stress on your system, leading to premature wear and tear. Our heat pump contractors will find the cause, whether it’s an electrical issue or an airflow restriction, and fix it before it leads to more expensive damage.

Why Is My Heat Pump Making Loud or Strange Noises?

A heat pump should run quietly—so if you suddenly hear rattling, grinding, buzzing, or squealing, something isn’t right. Different noises mean different problems:

• Rattling could mean loose panels or internal components.
• Grinding or squealing often signals a motor or belt issue.
• Buzzing may indicate an electrical problem or failing capacitor.

Our heat pump specialists will listen to the noise, pinpoint the issue, and get your system running smoothly again before minor issues turn into major failures.

Why Is My Heat Pump Frozen Over?

If your heat pump has ice on the coils, it’s struggling to function. This happens when airflow is blocked, refrigerant levels are low, or the defrost cycle isn’t working properly. Ice buildup can completely shut down your system if not addressed. Our team will check the defrost system, inspect the refrigerant levels, and ensure proper airflow to prevent further freezing.

Why Won’t My Heat Pump Switch Between Heating and Cooling?

Your heat pump should be able to switch seamlessly between heating and cooling. If it’s stuck in one mode, the likely culprit is the reversing valve—a small but essential component that directs the flow of refrigerant. A faulty reversing valve may need a simple reset, a repair, or a full replacement. Our technicians will diagnose the issue and get your system working properly again.

Why Won’t My Heat Pump Turn On at All?

A heat pump that won’t turn on at all can be caused by something as simple as a tripped circuit breaker—or as serious as a failed compressor or electrical issue. We’ll check for power supply problems, thermostat malfunctions, and damaged internal components to figure out what’s preventing your system from running. 

As an award-winning Carrier Factory Authorized Dealer, we have specialized expertise in Carrier heat pump systems, but our knowledge extends far beyond one brand. No matter what type of heat pump you have, our skilled technicians can fix it.

If your heat pump isn’t performing like it used to, you may be unsure whether to repair it or replace it. Some issues can be fixed quickly and affordably, while others signal that it’s time for an upgrade. At Hill-Air Heating & Air Conditioning, we provide honest assessments and expert recommendations so you can make the right decision for your home.

The key factors to consider are your system’s age, efficiency, repair history, and overall performance. Below is a simple breakdown to help guide your choice.

When to Repair Your Heat Pump

• System Age Is Under 10 Years: A newer heat pump system still has years of life left, and repairs are often the best option.
• Repair Is Minor: Small fixes like replacing a thermostat, capacitor, or sensor are cost-effective and extend the system’s lifespan.
• System Is Running Efficiently: If your heat pump has been performing well and this is the first issue, a repair may be all you need.
• Repair Costs Are Manageable: If the fix is less than half the price of a new unit, it often makes sense to repair instead of replace.
• Regular Maintenance Has Been Performed: A well-maintained heat pump will typically last longer, making repairs more worthwhile.

When to Replace Your Heat Pump

• System Age Is Over 10-15 Years: Older heat pumps become less efficient and more prone to breakdowns.
• Frequent and Costly Repairs: If you’ve had multiple repairs in the past few years, replacing the unit may be a smarter investment.
• Energy Bills Keep Increasing: An aging system can lose efficiency, leading to higher operating costs.
• Repair Costs Are Too High: If the repair bill is close to or more than half the price of a new unit, replacement is the better choice.
• Upgrading to a More Efficient System: New ENERGY STAR®-certified heat pumps provide better performance, lower energy costs, and improved home comfort.

No matter what you decide, Hill-Air Heating & Air Conditioning is here to help. Our goal is to help you make the best choice for your home—without pressure, just expert guidance and quality solutions.

The cost of heat pump repair depends on the type of issue, system age, and parts needed. 

On average, smaller repairs may cost a few hundred dollars, while extensive fixes can reach several thousand.

At Hill-Air Heating & Air Conditioning, we provide clear, upfront pricing with no hidden fees. If your system requires an extensive repair, we’ll help you explore heat pump replacement options and financing to find the best solution for your home.

If you’re already dealing with a heat pump breakdown, you know how frustrating and inconvenient it can be. The last thing you want is to fix your system today, only to have another issue pop up in a few months. That’s where regular maintenance makes all the difference. It’s not just about preventing problems—it’s about avoiding expensive repairs, lowering energy costs, and making sure your system actually lasts as long as it should.

Why Regular Heat Pump Maintenance Is Worth It

We recommend scheduling a heat pump maintenance tune-up with Hill-Air Heating & Air Conditioning at least once a year, or twice a year if you use your system for both heating and cooling year-round. Here’s why:

• Fewer Repairs, More Reliability: Most heat pump failures don’t happen overnight—they start as minor wear and tear that goes unchecked. Catching small issues early saves you from big repair bills later.
• Lower Energy Bills: A struggling system works harder, runs longer, and burns more energy—and that cost shows up on your utility bill. Regular tune-ups keep your system running efficiently.
• Longer System Life: A heat pump should last 10-15 years—but only if it’s taken care of. Skipping maintenance could mean a replacement years earlier than expected.
• Better Air Quality: A dirty heat pump circulates dust, allergens, and even mold into your home. Cleaning the coils and filters helps keep your indoor air fresh.
• Warranty Protection: Manufacturers require annual maintenance to keep warranty coverage valid. If you skip it, you could be stuck paying for a major repair out of pocket.

Let Us Handle It With Our Heat Pump Maintenance Plan

Keeping up with maintenance is easy when you’re part of Hill-Air’s Maintenance Plan. You’ll get seasonal tune-ups, priority service, and repair discounts—all designed to keep your system running smoothly without the hassle.

What are the most common reasons a heat pump stops working?

A heat pump can stop working for a variety of reasons, but the most common include thermostat malfunctions, refrigerant leaks, dirty filters, electrical failures, and frozen coils. Sometimes, the issue is as simple as a tripped breaker or clogged air filter, but other times, it requires professional diagnosis. If your system isn’t running properly, Hill-Air can troubleshoot and fix it fast.

What are the signs of a refrigerant leak in a heat pump?

If your heat pump isn’t cooling or heating as well as it used to, it could have a refrigerant leak. Other warning signs include hissing sounds, ice buildup on the coils, or an unexplained spike in energy bills. Refrigerant isn’t something you can just top off—the system needs to be properly sealed and recharged by a professional. Our team can check for leaks, repair the system, and restore proper refrigerant levels.

How often should a heat pump be serviced?

At a minimum, your heat pump should be serviced once a year, but if you use it for both heating and cooling year-round, twice a year is ideal—once before summer and once before winter. Regular maintenance helps prevent breakdowns, improve efficiency, and extend your system’s lifespan. Hill-Air offers maintenance plans to keep your heat pump in top shape.

What’s the typical lifespan of a heat pump before it needs repairs?

Most heat pumps last 10 to 15 years, depending on how well they’re maintained, how often they run, and the quality of the installation. Without regular maintenance, a system may fail much sooner. If your heat pump is over 10 years old and frequently needs repairs, it may be time to consider a replacement.

Why is my heat pump making strange noises?

Different noises mean different problems. Grinding or squealing could indicate a motor issue, rattling may be loose parts, and buzzing or clicking could be an electrical issue. If you hear anything unusual, it’s best to turn off the system and call a professional before the problem gets worse. Our expert technicians can quickly diagnose and fix the issue.

Is it worth repairing an older heat pump?

If your heat pump is under 10 years old and the repair is minor, it’s usually worth fixing. However, if your system is 12-15 years old, requires frequent repairs, or is driving up your energy bills, replacement may be the better option. Our team can help you compare repair costs vs. replacement and guide you to the best decision.

Are there any energy efficiency rebates or incentives available for heat pump replacements?

Yes! Many states and utility companies offer rebates, tax credits, or financing incentives for upgrading to an ENERGY STAR®-certified heat pump. Some manufacturers also have promotions on new systems. Hill-Air can help you explore available incentives and make sure you get the best possible deal.
