Heat Pump Services

Trusted Heat Pump Solutions Across Greater Houston and the Texas Gulf Coast

Is your heat pump blowing lukewarm air, making a harsh rattling noise through the walls, or driving up your power bill no matter how low you set the thermostat? When a system that handles both your heating and cooling starts acting up, it requires professional diagnostics before a minor mechanical issue turns into a catastrophic compressor failure. Mackey Services is ready to track down the root cause of your equipment failure and restore your home's comfort today.

We handle these exact heat pump meltdowns across Greater Houston and the Texas Gulf Coast regularly. The heavy, humid air in our region puts an incredible strain on your HVAC equipment, forcing it to work harder just to maintain baseline comfort. Perhaps you have noticed your system constantly relying on emergency auxiliary heat, spinning your utility meter out of control while failing to warm the house.

Our technicians arrive ready to test the electrical amp draw, check the reversing valve, and deliver honest, accurate solutions. We do not rely on pushy upselling or vague guesses when diagnosing your equipment. You get straight answers about what it takes to get your system running right, backed by years of field experience.

Heat Pump Repair & Service

When your heat pump starts failing, the symptoms are hard to ignore and demand immediate professional attention.

Because these units handle both your heating and cooling, they do not get an off-season to rest. That constant run-time means components wear down significantly faster than a traditional split system. We get calls every day from homeowners dealing with sudden spikes in their electricity bills or burning electrical smells near the outdoor condenser.

Mechanically, the most common failure modes we see involve the reversing valve getting stuck. This prevents the system from switching modes between heating and cooling. We also routinely replace pitted contactors and blown dual-run capacitors that simply give out under the constant workload.

Another common issue unique to heat pumps is a malfunction in the auxiliary heat strips. When the system cannot pull enough heat from the outside air, these strips are supposed to help, but a faulty sequencer can leave them running constantly. If a failing unit trips your breaker repeatedly, it might seem like an electrical issue, but skipping your annual Heat Pump Maintenance & Tune-Up is usually the root cause of the mechanical strain.

Common failure modes we diagnose in the field:

• Stuck reversing valves preventing the system from switching modes
• Pitted contactors that fail to engage the compressor safely
• Blown dual-run capacitors that give out under heavy workloads
• Refrigerant leaks in the evaporator coil causing weak airflow
• Failing defrost control boards leading to iced-over outdoor units

When our technicians arrive, we never just guess at the problem. We test the electrical amp draw on your compressor and check the subcooling and superheat to verify the exact refrigerant charge. We also test the defrost control board to pinpoint the exact point of failure.

In this trade, blunt honesty matters. Catching a weak capacitor or a failing fan motor early is a straightforward, affordable repair. Letting it run until it takes out the compressor turns into a massive, expensive nightmare.

Whether you have a minor electrical issue or a major mechanical failure, our Heat Pump Repair & Service team handles every call across Greater Houston and the Texas Gulf Coast.

Heat Pump Installation & Replacement

There comes a point where patching up an old, failing system stops making financial sense and a full replacement is the only logical step.

Customers often complain about hot and cold spots throughout the house or a system that runs non-stop but never actually reaches the set temperature. A successful heat pump installation is entirely about the math, the airflow, and the execution. What goes wrong systemically in our industry is poor sizing by contractors who skip the critical load calculations.

An oversized unit will short-cycle, leaving your house freezing but completely damp and humid. An undersized unit will run constantly and burn itself out in half its expected lifespan. We perform strict load calculations to size the equipment correctly for your specific square footage and thermal envelope.

Modern heat pumps are rated by SEER2 for cooling and HSPF2 for heating efficiency. Upgrading from an old, single-stage compressor to a modern variable-speed unit means your system can ramp up and down in tiny increments. This provides exact temperature control and superior humidity removal without the massive power draws of older equipment.

Signs it is time to replace your aging heat pump:

• The unit is over 10 to 12 years old and requires frequent repairs
• Your system runs on phased-out R-22 refrigerant
• You are facing a catastrophic compressor failure
• Energy bills have doubled despite regular filter changes
• The system struggles to maintain a consistent indoor temperature

During installation, we evaluate your existing ductwork to ensure it can handle the required airflow. We also upgrade the electrical whip and disconnect box for safety. Our installers always braze the copper refrigerant lines with nitrogen to prevent internal oxidation.

If your current setup is constantly breaking down, paying for another Heat Pump Repair & Service visit might just be throwing good money after bad. Instead of throwing good money after bad on a dying system, a proper installation gives you reliable, balanced comfort. You get a reset clock on your equipment's lifespan and peace of mind during extreme weather.

Heat Pump Maintenance & Tune-Up

Most heat pump emergencies are entirely preventable with proactive, routine care before the extreme weather hits.

Because a heat pump operates year-round, it pulls double duty compared to a traditional split AC system. That means it pulls in twice the dust, takes twice the electrical wear, and requires twice the attention. The early warning signs of a neglected system are subtle, like a unit running a little louder than it used to or a musty smell when the blower kicks on.

The Gulf Coast environment is incredibly harsh on outdoor coils, coating them in salt, dirt, and grime. This buildup suffocates the system's ability to transfer heat effectively. During a maintenance visit, we look closely at the components that quietly degrade over time.

We also inspect the outdoor unit's base pan to ensure drain holes are clear, preventing ice buildup during the winter defrost cycles. A neglected base pan can cause ice to expand and crush the delicate aluminum fins on your condenser coil. If a routine check reveals severely worn or failing components on a very old unit, we will immediately recommend a Heat Pump Installation & Replacement consultation to discuss your options.

What we check during a routine maintenance visit:

• Washing the condenser coils to ensure proper heat transfer
• Flushing and clearing the condensate drain line to prevent ceiling leaks
• Checking the subcooling and superheat to verify the exact refrigerant charge
• Tightening all electrical connections that vibrate loose over time
• Measuring the amp draw on the blower and condenser fan motors

Skipping your annual tune-up might save you a little cash today, but it is a massive gamble with your comfort. A clogged drain line will eventually flood your ceiling, causing extensive water damage. Running a heat pump with a dirty coil forces the compressor to run at extreme pressures until it inevitably fails.

Routine maintenance is the cheapest insurance policy you can buy for your HVAC system. It keeps your warranty valid, lowers your monthly power bills, and extends the life of your equipment.
