What Are The Signs Of A Bad Heat Pump Installation?

Heat pumps are designed to keep you and your family members warm and cozy when the temperature outside is freezing. Although heat pumps are quite simple to install, some greedy individuals can easily mess up the process, preventing your heat pump from performing at its best and making you seek heat pump repair often. Here are some tell-tale signs that point to a bad heat pump installation.

Low Airflow

One of the tell-tale signs of an improperly installed heat pump is low airflow. A heat pump will only be effective if it can produce a strong airflow and circulate it evenly among the rooms. However, if the installation job is poor, not only will the heat pump struggle to circulate air efficiently but might also face complications in performance.

Believe it or not, this could also affect the unit’s life. Modern heat pumps are smart and loaded with features that help with effectiveness and cost savings. However certain external factors can hinder their performance, which could burden the components and eventually result in expensive repairs and replacements of HVAC components.

Depending on the season, you might notice that some areas in the house are colder than others. It likely has to do with low airflow. The reason is when inexperienced workers install heat pumps, they tend to use techniques and duct and vent networks that are not compatible with the unit.

Both undersized and oversized networks tend to create problems for the heat pump. As a result, your comfort suffers.

Electrical Problems

Heat pumps are electrical appliances meaning they use electricity as a fuel. Although heat pumps are technologically advanced nowadays, poor installation jobs can still create a lot of problems. For instance, while installing the unit, an inexperienced individual might leave some wires or connections either too loose or close to each other.

If the wires tend to be overlapping or are too close, it might lead to a fire. On the other hand, the vibration of the heat pump might loosen the connections causing it to shut down midway. In such situations, the homeowners are most likely to blame the unit.

This is why it is suggested to hire a expert who is skilled and licensed. This way, you can be sure the connection was properly navigated and secured throughout the installation.

Operational Issues

Heat pumps produce efficiency through what is called a cycling process. Every heat pump comes with a pre-programmed cycling routine that allows the unit to achieve the desired temperature in the shortest span and reduce electricity consumption as well.

However, if the heat pump has not been installed properly, the unit might cycle short or long. There continue to be many cases where homeowners complain about their heat pumps being irregular in terms of cycling. Meanwhile, the experts have to deal with a problem that shows no signs or symptoms.

This could be a frustrating issue on both sides as neither is clear on what to do. Short cycling refers to frequent operational cycles that do not last long enough. Long cycling means operational cycles that last longer than 20 minutes on average.

Both types put significant stress on the components and make it a lot harder for the unit to perform. An obvious sign you will observe is the sudden increase in your electricity bills. Short and long cycling simply wastes energy. In such a case, you will need to hire a smart technician who is aware of the possibilities and can deal accordingly.

If you have recently purchased a new unit and observe a disturbance in the cycles, you should make sure there are no leaks or room for air to escape and the heat pump is installed the right way. Sometimes, the cycling process may also get disturbed due to cracks, damage, or holes in the vents, doors, windows, etc.

Then again, to spot issues in such areas, you are going to need a technician who tracks the issue using the clues and does not get right down to blaming your HVAC unit.

Parts Wear Out Quickly

Most heat pumps do not require repairs until they are 5 to 10 years old. However, homeowners can prolong the lifespan by providing the heat pumps with proper maintenance. But, an improperly installed heat pump will most likely not make it to the five-year mark.

Soon, the heat pump will need repairs and replacements. Because heat pumps have to function daily during the winter season, the stress can take a toll on the components. You need to keep in mind that improper installation adds unnecessary stress.

If that is the case, do not be surprised if your heat pump requires frequent repair. It’s better if you let an professional from HVAC companies Port Jefferson inspect the entire HVAC system and fix it.

Poor Indoor Air Quality

Improper heat pump installation can also lead to bad indoor air quality. If you observe that the air in your home has suddenly become thick and humid, it means there is something wrong with the heat pump. Excessive humidity in the air indicates poor indoor air quality.

In most cases, a wrong type of refrigerant usage tends to be the culprit. Refrigerant leaks are common in older units and will require refilling. However, depending on the model and type, the refrigerant will vary as well. An inexperienced technician will use the wrong type and cause the unit to stress out.

On the other hand, older units need to be thoroughly inspected first to make sure there are no cracks, leaks, rust, etc. At the same time, if you have recently bought a new heat pump and the indoor air quality is not impressive, it most likely means the unit needs some adjustments.

No Permit Inspection

When it comes to installing heat pumps, some states have strict regulations that both homeowners and installers need to follow. A licensed individual will inform the local authority right after the installation to check their work. The authority will send an inspector to check the quality of the work. If the work is found satisfactory, the authority will issue a permit or certificate stating that the HVAC system installation meets the industry standards.

Therefore, if your region or state has such laws, you should expect the installer to inform the relevant department. If they avoid doing so, it means the installation was most probably fishy as well. That said, if you observe some complications right after, you should already know where the problem lies.

Outdoor Unit Noises

Outdoor units are installed on concrete pads that are made for this purpose. It ensures that the condenser unit is provided with a solid and level surface to avoid any functionality issues. However, if the concrete pad is not level or if the outdoor unit is not placed on it correctly, it will be unstable.

This is causes loud and unfamiliar noises from the outdoor unit whenever the compressor starts functioning. You need an expert for checking the outdoor unit.


Catching a poorly installed heat pump can be a challenge. However, considering the tips mentioned above, you will at least have an idea of where to look. But, make sure you always hire a licensed heat pump repair service Huntington and keep an eye out for unusual signs and symptoms that might need immediate attention. Otherwise, you will end up with heat pump problems.
