The Maryland HVAC contractors at Presidential Heat and Air recently released a blog answering the question, what does an HVAC compressor do? These compressors are a critical element of HVAC systems, allowing the system to cool and dehumidify a home.

An HVAC compressor powers the entire heat transfer cycle, which moves hot air from an enclosed space to the outdoors to cool the space. The cycle begins when the compressor squeezes the refrigerant, raising its temperature and pressurizing it to the liquefying point. The refrigerant can then flow into a condenser coil, where a fan facilitates the transfer of excess heat and allows the refrigerant to flow into an evaporator coil. When the cold evaporator meets the warmed refrigerant, humidity is drawn from the air. The compressor can then push hot, pressurized refrigerant toward the condenser and pull the vaporized refrigerant from the evaporator to start the cycle over again. Because of its central role in the cooling process, your compressor should be regularly checked for damage or wear and tear due to age so that your HVAC system continues to provide cooling for your home.

'Without a functioning compressor unit, your HVAC system will not be able to operate effectively. This is particularly worrisome during the hot summer months, when a working system becomes essential. HVAC prevent your home from reaching dangerously high levels, which can not only cause discomfort but can also put children and elderly residents at risk of heatstroke and other serious conditions. If you feel that your compressor may not be working, be sure to contact an HVAC contractor to repair your system before the heat increases.
