Residential HVAC technicians install and repair home heating and air quality systems, as well as refrigeration systems (this is why the profession is also often referred to as HVACR). They might specialize in installation or repair, certain types of systems or equipment. Additionally, residential HVAC technicians may be responsible for selling maintenance contracts to customers. Prior to installing an HVAC system, technicians review specifications and explain to clients the varying product options. Once an agreement has been reached, they set up the system, which can include installing pumps and air ducts. Residential HVAC technicians may periodically return to check up on the system and perform any preventative maintenance, as well as troubleshoot system issues as they arise; they adjust system settings and conduct performance tests using specialized tools.
