HVAC-R Service & Repair
What is HVAC-R? (Heating, Ventilation, Air Conditioning and Refrigeration) is a system of controlling temperature, humidity, & air quality in indoor spaces. The goal of an HVAC-R system is to provide an acceptable level of indoor air quality & thermal comfort. The system’s designs are based on the principles of heat-transfer, thermodynamics, & fluid mechanics. There are a few variations that can include other aspects, like:
HVAC-R systems are used in both commercial and residential establishments. They play a vital role in ensuring that the climate within the structure is comfortable and that stale air is replaced with fresh air from outside.

We want to make sure your system is up and running so that you and your family are well taken care of.
- HVAC&R or HVACR – The ‘R’ is used to indicate that the system includes refrigeration.
- HACR – These are systems that include refrigeration, but NOT ventilation.

Individual Systems
In modern buildings, one or more HVAC systems are incorporated in the building’s design, along with control systems for manipulating their performance. For small buildings or residences, contractors usually estimate the required capacity based on the interior dimensions, and then select and incorporate the HVAC system accordingly.
Larger buildings, however, are thoroughly analyzed by building service designers or engineers who then specify the appropriate configuration of the HVAC systems needed, which are fabricated by specialty mechanical contractors. Buildings of all sizes must clear code-compliance inspections and obtain relevant building permits.

Heating
The heating system generates and distributes heat to the entire area covered by the HVAC. Heat generation can be achieved with boilers, furnaces, or heat pumps that circulate hot water, steam, or directly heat the air in a central location, like furnace rooms in houses or mechanical rooms in larger buildings. The heat is transferred by radiation, conduction, or convection.
Air Conditioning
Air conditioning systems are used to reduce the temperature and control the humidity of the air being circulated. Most of the air is recirculated, but fresh air from outside is also drawn in, creating positive pressure in the space. All the air being moved is passed over a heat exchanger, which is mechanically cooled, and then circulated to the areas that need it.
Both air conditioning and refrigeration are achieved by removing the heat through radiation, conduction, or convection. The mediums used to conduct the heat are called refrigerants, which are circulated through a refrigeration system or a free cooling system.

Refrigeration
Refrigeration is a process of removing heat from a low-temperature reservoir and transferring it to a high-temperature reservoir. The work of heat transfer is traditionally driven by mechanical means, but can also be driven by heat, magnetism, electricity, laser, or other means. Refrigeration has many applications, including, but not limited to: household refrigerators, industrial freezers and air conditioning.
