Heat Pumps in Burlington County, NJ

Dependable Heat Pump Diagnostics and Repairs Across Burlington County

Is your heat pump stuck blowing cold air when you need heat, covered in a solid block of ice, or jacking up your electric bill by running constantly in auxiliary mode? Heat pumps are complex machines that run 365 days a year, meaning these specific failures require professional diagnostics to prevent compressor damage. Gibson Home Services is ready to pinpoint the exact mechanical or electrical failure and restore your home's comfort today.

Signs Your Heat Pump Needs Professional Attention

The System is Stuck in One Mode

You switch the thermostat from cooling to heating as the weather changes, but the air coming out of the registers does not change temperature. The reversing valve—the component responsible for changing the flow of refrigerant to switch the system between heating and cooling—is likely stuck or its electrical solenoid has burned out. You will be left without the climate control you need, and the compressor can quickly overheat and fail if it fights a mechanical blockage inside the valve.

Frost or Solid Ice on the Outdoor Unit

The metal fins on the outdoor cabinet look like a solid block of ice, or you notice a heavy, thick layer of frost that never seems to melt off during the day. While a light dusting of frost is normal in certain conditions, a solid block means the system's defrost cycle is failing due to a bad control board, a faulty sensor, or a severe refrigerant restriction. If the ice builds up enough, it will crush the fragile aluminum fins, snap the fan blades, and ultimately destroy the compressor.

Unusually High Electric Bills

Your energy bill spikes dramatically without a significant change in your daily usage, your habits, or the outdoor temperature. The heat pump is struggling to maintain the set temperature and has defaulted to emergency heat strips, which use massive amounts of electricity compared to the highly efficient compressor. Beyond the immediate financial hit, the underlying inefficiency causing the system to struggle will eventually wear out your blower and fan motors.

Strange Noises from the Compressor or Air Handler

You hear loud grinding, metallic rattling, or a distinct hissing sound coming from the indoor or outdoor unit. Grinding usually points to failing motor bearings, rattling could be an unbalanced fan blade, and hissing is often high-pressure refrigerant escaping through a leak in the copper lines. Catching a bad bearing early saves an expensive motor, and catching a refrigerant leak early saves the compressor from a catastrophic burnout.

Short Cycling Constantly

Your system turns on, runs for just a few minutes, and abruptly shuts off before the house reaches the temperature you set on the thermostat. This rapid on-and-off cycle usually indicates a low-pressure lockout from a refrigerant leak or an overheating compressor shutting itself down to prevent an electrical fire. Ignoring this violent cycling will completely fry the electrical contactors and send the compressor to an early grave.

Auxiliary Heat Running During Mild Weather

You notice the auxiliary or emergency heat indicator illuminated on your thermostat when it is fifty degrees outside. This backup heating mode is only designed to activate when outdoor temperatures plunge below freezing and the heat pump cannot extract enough ambient heat. If it kicks on during a mild afternoon, your compressor is likely failing to pump refrigerant or the outdoor unit is suffering from severe airflow restrictions.

What is Causing Your Heat Pump to Fail?

Refrigerant Leaks and Low Charge

Unlike traditional air conditioners, heat pumps run year-round, meaning their coils and copper lines endure constant pressure changes and vibrations 365 days a year. Over time, this constant environmental wear creates micro-leaks that allow the vital refrigerant to escape into the atmosphere. We locate the leak using electronic sniffers, repair the compromised copper line, pull a deep vacuum, and weigh in the exact factory specification of refrigerant to restore proper operating pressure.

Defrost Control Board Failures

High humidity combined with fluctuating temperatures causes outdoor units to frost up frequently, forcing the defrost control board to work overtime. When the board or its thermistor sensors fail due to electrical wear or moisture damage, the system turns into a useless block of ice. We test the thermistors and measure the board's voltage output to determine if a replacement board will restore the unit's ability to successfully clear its own coils.

Faulty Reversing Valves

The reversing valve is the mechanical heart of a heat pump, and its internal slide mechanism can jam due to tiny amounts of system debris. If it is just the electrical solenoid that failed, it is a quick and straightforward swap to get the system shifting modes again. If the internal valve body itself is jammed, we must recover the system's refrigerant, safely braze in a new valve, and recharge the system entirely.

Clogged Coils and Airflow Restrictions

Because heat pumps do not get an off-season like a dedicated furnace, their filters and indoor coils load up with dust, hair, and pet dander twice as fast. This chokes off the vital airflow required to transfer heat in or out of your home. We perform a deep chemical clean of the evaporator and condenser coils, clear the blower wheel, and check the motor's amp draw to ensure unrestricted airflow is restored.

Electrical Contactor and Capacitor Failure

Heat pumps require a massive jolt of electricity to start the compressor and keep the fan motors spinning against heavy air resistance. The capacitor acts as a battery to deliver this jolt, while the contactor is the mechanical switch that allows high-voltage power to flow into the unit. When these components pit, burn out, or lose their charge from constant use, we safely discharge the old electrical components and wire in OEM-spec replacements to restore reliable power delivery.

What to Expect When We Inspect Your Heat Pump

When you call Gibson Home Services, you are getting a licensed NJ Master HVACR contractor at your door. We start by listening to you because we want to know exactly when the strange noises started, how long your energy bills have been creeping up, and what you have already tried. From there, we do not just guess at the problem or throw expensive parts at the system hoping something sticks.

We hook up digital gauges to check the refrigerant's subcooling and superheat, test the reversing valve voltage, and manually initiate a defrost cycle to see exactly where the system is failing. We inspect the electrical contactors for pitting and measure the capacitor's microfarads to catch failing components before they leave you stranded. We also evaluate your indoor air handler to ensure the blower motor is pulling the correct amperage and pushing enough air across the coils.

Comprehensive Climate Control Services

Sometimes a heat pump issue points to a broader need within your home's HVAC setup. If your system is aging and the cooling side has completely failed, we provide expert air conditioning repair to get things running, or full air conditioning installation if the unit is simply beyond saving. For homeowners looking to supplement their current setup or condition a specific problem room, we also specialize in high-efficiency ductless systems that offer the same heating and cooling benefits without the need for traditional ductwork.

Restore Your Home's Comfort Today

Living with a malfunctioning heat pump means dealing with uncomfortable rooms, unpredictable temperatures, and energy bills that keep climbing. You should not have to guess whether your system is going to keep you warm tonight or cool tomorrow.
