The HVAC industry (heating, ventilation, and air conditioning) is divided between installation and technician work, with some professionals performing both.

Rosie on the House generally focuses on the homeowner. Over the next few weeks, we will focus on the construction professional. Today, we will cover a day in the life of an HVAC installer and technician.

When the temperature in our homes is comfortable, we tend to forget about the people who make our comfort possible. On that first cold morning when the winter chill arrives and the heat doesn’t kick on, we may find ourselves scrambling for an HVAC contractor.

The HVAC industry (heating, ventilation, and air conditioning) is divided between installation and technician work, with some professionals performing both. According to the industry group Advanced Energy Economy, half a million people in the U.S. are employed in the high-efficiency HVAC sector, with another 600,000 spending at least some of their time on the job working with high-efficiency HVAC equipment.

The difference between an installer and a technician

When you call an HVAC company, either an installer or a technician will come to your home. There is a difference between HVAC installers and HVAC technicians, as explained by North American Trade Schools. HVAC installers are primarily responsible for installing new HVAC systems, and technicians focus on maintaining and repairing existing HVAC systems. Both require a good understanding of how HVAC systems work.

Installers tend to be more involved in the construction industry than technicians. When a new building is under construction, it is the HVAC installer who sets up the HVAC system. Whereas, technicians tend to work with home and business owners with an existing HVAC system that needs repairs or maintenance.

A day in the life of a residential HVAC professional

Andrew Dobbins, owner, Intelligent Design Air Conditioning & Heating, a Rosie-Certified Partner, takes us through a typical day of one of his eight technicians and 10 installers.

The installers and the technicians arrive at the yard at 6:30 a.m. They clear their vehicles of the remnants from the previous day’s jobs and reload parts needed for the day. They use a checklist to ensure they have all the equipment they will need for the day.

Roughly an hour later, they are off to their first job of the day. Though, one day a week they attend either the installer or technician meeting before heading out.

When the installer arrives, they will introduce themselves to the homeowner and walk them through what the job will entail. The installer remains until the job is finished. Once the new unit is installed, the airflow is checked and the thermostat installed.

The homeowner is then taught how to use the thermostat. Before leaving, the installer will take pictures of the finished job and upload them to a service system so the install manager can review them. The manager will either authorize the completion of the project or instruct the installer to make adjustments.

For service calls, upon arriving and meeting with the homeowner, the technician will first assess what is wrong with the unit. Once the problem is identified, it is discussed with the homeowner, fixed, and the payment collected. Sometimes parts need to be ordered.

The technician will return to finish the job and the collect any balance due . A technician generally goes on four to six calls a day in the peak season which runs April through September. Calls pick up in January and February for heating issues. Between those months, service technicians are performing routine maintenance and pre-heating checks.

The hours that HVAC technicians and installers keep tend to differ. HVAC installers are typically able to set their appointment schedules, pending the arrival of the crane and unit.

Technicians are servicing homes and businesses; therefore, their schedules need to accommodate those of their customers. Sometimes they need to be on-call.

“During the non-peak season, an installer can be done by noon or 6:00 p.m. It totally depends on the day,” says Dobbins. “Installers may not have a job for the day. If that’s the case, they can spend their day doing something with their family.”

It’s different for technicians. “When you are dealing with existing homes, there are always jobs to be had. We always plan that something will come up on a 30-year-old-house that we weren’t expecting,” he says.

Their work requires a lot of physical stamina. When the end of the day comes, especially in the summer, they are wiped out. Dobbins says his installers and technicians have gotten used to the physicality and the heat that comes with the job.
