Results of a Poorly Installed AC Unit

Posted On: July 21, 2015

With the advent of highly efficient air conditioning systems homeowners are able to lower their utility bills, if the system is properly installed. A system that is not properly installed can waste hundreds of dollars in energy and lower the lifecycle of the system. According to surveys conducted by NIST, improperly installed equipment causes degraded equipment performance.

Signs of Improper HVAC Installation

Faulty air conditioner installation errors can compromise stated energy efficiency ratings, and in the end can lead to the degradation of equipment and early failure of the system. There are many things that can go wrong when it comes to the installation of your unit, including:

Wrong unit size – An undersized HVAC unit will need to work harder than necessary, which can affect the life of the unit. Conversely, an oversized unit will cost more to purchase and operate, which can cause increased costs.

Too little refrigerant – Upon installation, an HVAC unit must be charged with refrigerant. A system that has too little can be slower to cool on hot days resulting in a home that does not cool properly.

Too much refrigerant – On the other hand, a system can be overcharged with refrigerant can freeze the lines causing the system to overwork.

Improper subcooling of liquid line refrigerant – An issue caused when an HVAC unit is improperly charged with coolant. If consistent, it can cause a shortened lifespan of your HVAC system.

Improper air flow – Ductwork needs to be as airtight as possible when it is installed. When installed improperly it will suffer from leaks or blockages, which can cause some rooms to be cooler than others and can cause your HVAC system to overwork.

Improper power to the System – The amount of electricity going to the unit is also critical to a system that operates properly and too much voltage to the system may cause a short and too little may prevent the system from operating properly.

Non-condensable gasses – When coolant lines are not properly pressure set, it could potentially blow out the lines in your system, causing loss of coolant and failure of the system.

The most common installation error found by the NIST study is improperly installed and sealed ductwork. However, the study also found that leaky ducts combined with any of the other poor installation issues add to the effects of energy consumption.
