Some of the different services can include the installation, repair, and maintenance of refrigeration, heating, and air conditioning systems. The person that offers these services is called an HVAC technician (Heating, Ventilation, and Air Conditioning). They are specifically trained to install, diagnose, maintain, and repair the mechanical and electrical components of those systems. They are also familiar with the refrigerant and fuel that these systems need. A company might provide heat and air conditioning service to industrial or residential customers or combination.
A HVAC service they offer is the installation of air conditioning or central heating systems. During installation it not only requires the connection of the appliance but could also include installing the ductwork. This consists of the tubing and piping that runs to and from the system. They may also have to complete any wiring that is necessary. Once the system has been installed the service company will check the performance of the system using specific tools. Some of the initial system checks could include making sure that the unit controls and equipment are properly functioning. They will also make sure that there is the absence of fuel or air leaks anywhere in the new system.
Another service that is offered is the yearly maintenance of the heating and cooling systems that generally involves the checking of the various components of the system. The technician may check the voltage of the unit’s electrical components and tighten connections. They may also put the equipment through a working cycle to make sure all the components are operating safely and properly.
When doing a heat and air conditioning service just on the heating system there is specific maintenance that is done. This can involve checking the oil or gas connections for health or fire hazards. The technician will use special instruments to check whether the gas enters the furnace at the correct pressure level. They will also visually assess the heat exchanger and burner combustion for any signs of damage and dirt. If so, they can deter the system from operating safely and efficiently.
When doing a service check on a central air conditioning system it involves different checks such as making sure that the drains will allow the condensation to adequately flow. If you have air conditioning components that are defective or dirty they can escalate the cost of operating the system and affect the efficiency of the unit. The unit will run for a longer period of time if the coils of the air conditioner are not clean. The refrigerant levels will also be checked,
