A multi-family HVAC central air system is an efficient, practical and relatively common solution for air conditioning several apartments simultaneously. Unlike split models, which have individual units in each room, the central system uses a single external unit (condenser) and several internal units (evaporators) distributed throughout the apartments, where each resident makes their adjustments according to their needs and preferences.
The functioning of a central air conditioning system works in a very similar way to the split system, for example, which is the most common individual air conditioning model today, it works as follows:
Condenser unit
As it is a central and unique system for the entire building, the condensing unit is larger than the common ones and is installed outside the building. It is responsible for cooling the refrigerant gas that will supply cold air to the apartments.
Evaporator unit
Evaporator units may vary in model depending on what was chosen for the residential building, but they are always installed inside each apartment, to distribute cold air and remove heat from the environments.
Piping
They conduct the refrigerant gas between the condensing unit and the evaporators. This is generally an area that requires more attention and maintenance to avoid problems.
Control system
This is what allows each resident to regulate the temperature and air flow in each room of the apartment. Find the best multifamily hvac contractors.
Maintenance on a central air conditioning system
Every air conditioning system, from the most complex, such as central systems, to the simplest, such as individual systems, requires regular and preventive maintenance. This is to prevent the costs of repairs and repairs from being large and causing losses for residents. Discover the main maintenance points in an air conditioning system:
Preventive maintenance
It is necessary to hire an experienced professional who guarantees the quality of the inspection and technical services, as preventive maintenance aims to identify possible and future problems and resolve them before they become harmful to the multi-family hvac system or generate high costs. to residents.
Cleaning the air filters and evaporator
This is essential care that must be carried out inside each apartment, as the filters are what guarantee the quality and purity of the air, keeping the health of the entire family safe, as well as the cleanliness of the appliance installed in the apartment, which will ensure full functioning of the air conditioning.
Refrigerant gas check
Refrigerant gas is basically the fuel that cools the air that is distributed by the central air conditioning system. This gas needs to be checked and in some cases replaced or exchanged so that the system remains intact and functioning at its maximum capacity and efficiency.
Inspection of piping and electrical connections
Inspections of electrical connections are essential to ensure the safety and integrity of the building and apartments. Maintenance and inspections of the air conditioning’s electrical connections prevent the system from suffering from short circuits. Inspecting the pipes serves to remove the accumulation of residue and dirt that settles there over time.
Cleaning ducts is essential to ensure air quality and avoid health problems. The frequency of cleaning depends on the use of the system and the amount of dust in the environment, but is generally recommended every 6 months.
Thermostat Calibration
The thermostat works by managing the need to cool an environment or not, that is, if this instrument is well calibrated it means that the system will not be forced to work more than necessary, saving energy and increasing its efficiency and longevity.
Corrective maintenance
It must be carried out in case of malfunctions or failures in the system. It usually occurs due to lack of care or severe damage caused by some factor beyond the control of preventive maintenance.
