Keeping Their Cool
This article on air-conditioning service and repairs exemplifies the unseen and oftentimes unappreciated efforts of mechanical contractors. These types of service calls and repair projects can be dangerous to the workman if one is not familiar with all of the hazards involved.

It’s hot, and their job is to keep it cool.

It’s nearing 8 a.m. at Acme Air Conditioning Company, 2626 Central Avenue, and the company’s six servicemen have been there half an hour already.

A plastic, yellowing Friedrich thermometer hangs on the back wall of the garage. It registers 84 degrees already. The relative humidity outside is 88 percent.

It’s only going to get hotter.

The workers are gathered in the store’s repair shop to complete the necessary chores before the white Acme vans head to their first assignments of the day. The men, dressed in navy pants and pinstriped shirts with their names emblazoned on them, restock spare parts they used the previous day. They clean the trash and debris that accumulated in the vans from earlier repairs. They load the units they will be installing that day. And most important, they take a few moments just to chat.

The workers at Acme range in age from summer employee Jason Dunkman, a 17-year-old Gibbs High School student, to Bernie Hunt, a 76-year-old veteran. The patriarch of the group is Hartley Skibo, an Acme employee for 32 years and the company’s system designer and service manager. He assigns the two-man crews to the job sites each day and travels from site to site to monitor progress.

Skibo is a fixture each morning in Acme’s garage, which resembles that of an old-fashioned car mechanic’s, except for the air conditioning units strewn about the place. Rusty tools are scattered across a weathered wooden workbench.

Inside the office, the phone rings constantly. It’s part of the summer norm. Co-owner Lorin Bridge estimates the company received 200 to 250 calls a week just for service.

“People are frantic this time of year,” he said. “They know they needed to do maintenance on their system in the fall, but they wait until they need A/C to call. Then they have to wait. But they want service now; they are dying. We try to keep everybody happy, but it’s hard in the summer.”

Shortly after 8 a.m., the Acme fleet rolls out in synch like a 20th century version of the cavalry. Repairmen have come to the rescue of overheated citizens since William Carrier developed the first residential air conditioner in 1928. The day promises to be long and sweaty.

“It is extremely busy right now; every summer is especially busy,” Skibo said. “We usually have triple the business. It’s hard to keep up sometimes.”

Part of the problem these days, Skibo said, is finding qualified workers.

“You can’t hire a good mechanic these days. No one wants to go up in an attic that’s 150 degrees. It’s tough work. You have to know electricity, plumbing, duct work and even design.”

Skibo is proud of the workers he has, two of whom are on the roof of the  Salvation Army building, at 3800 Ninth Avenue North, by 8:30 a.m. The problem with the old Carrier Weathermaker is a rusted drain pan that is leaking through the ceiling below. Skibo’s solution: Scrape the rust off, and seal the entire pan with a layer of epoxy. Problem solved.

After scraping off a layer of rust and waiting for Skibo to return with the epoxy, repairman Jeff Colon is sweating heavily. Still, he said he doesn’t mind the hectic pace of summer.

“We work on average six days and from 50 to 60 hours a week in the summer, sometimes more,” said Colon, who has worked for the company since the early 1990s.

“In the winter months a lot of repairmen get laid off. Usually (Acme) finds a way to get us enough hours, but it’s a lot slower. So it’s nice to have the work. If anything, this time of year is definitely busy.”

Within a couple of hours, the job is finished, and the Acme crew is off to another assignment. During the course of the day, they will visit Sterling Cleaners and a couple of private homeowners. Other Acme crews will visit Bayfront Towers, Azalea Baptist  Church, Lithos Jewelry and Pasadena Community Church. Later in the day, Greg Minton, service manager for St. Petersburg Heating & Air Conditioning at 4801 122nd Avenue North, is across town at the home of an elderly couple who lost air conditioning that morning after a power surge. It’s stuffy inside, and the hall thermostat registers 83 degrees.

Minton, 31, was raised in the business and is accustomed to the summer heat. “We don’t work in the A/C,” he chuckles. “We work to get people A/C.”

Aside from time away to study engineering at the University of Kentucky, he has worked in the field roughly 14 years. His experience allows him to identify the problem in only a few minutes. It’s the worst case scenario—a shorted compressor, which means the system needs to be replaced. Even though it is almost 6 p.m., Minton offers to stay and install a new unit. The owners gratefully take him up on it.

Between 5 p.m. and 7  p.m., the Acme cavalry vans filter back to the dusty garage one at a time. The men say little as they disperse and head home for the evening. There will be time for talk when the ritual begins again tomorrow morning. And when it does, Hartley Skibo will be there, just as he has been for 32 years.

“I love my work,” he said. “You just never know what you are going to get to do on this job. And the customers, they love us this time of year. That part is a lot of fun.”

Across town, Minton finishes installing the new unit by 7:30 p.m. Only 12 hours until time to start again. That’s nothing compared to some of the 3 a.m. calls he has answered before. And tonight’s late finish hasn’t wiped away his perpetual smile.

“I really love my job,” he said. “This is my life, what I like doing. Most people are really kind and appreciative, and that makes going up in a hot attic a little easier.

“When I leave and my customers are happy, that is its own reward.”


Code Compliance and Maintenance
Key to Hazardous-Free Installations

This article on air-conditioning service and repair exemplifies the unseen and oftentimes unappreciated efforts of mechanical contractors. These types of service calls and repair projects can be dangerous to the workman if one is not familiar with all of the hazards involved.

Personnel Protection Required
The National Electrical Code includes some requirements that are intended to protect workmen and service personnel from electrical hazards when working on rooftops or in confined spaces, such as crawl spaces and attics. Section 210-63 requires that a 125-volt single-phase, 15- or 20-ampere-rated receptacle outlet be installed at an accessible location or servicing heating, air-conditioning, and refrigeration equipment on rooftops, in attics, and in crawl spaces. This receptacle is to be located within 25 feet from the heating, air-conditioning and refrigeration equipment, and at the same working or building level as the equipment. The last requirement in Section 210-63 is that this receptacle not be connected to the load side of the equipment disconnecting means.

This same requirement also appears in the mechanical codes. This was warranted by service and maintenance personnel not usually aware of all of the electrical hazards involved. This required receptacle serves to help negate situations in which the workman would be exercising less than acceptable practices to obtain electricity for power tools and aspects of their service operations. This often includes, but is not limited to, makeshift extension cords, alligator clip connections to the line side of service disconnects, use of cords without proper grounding connections, etc. The Code has  improved the safety factor for serviceman personnel by requiring this service receptacle.

The Code goes further and requires in Section 210-8(b)(2), in other than dwelling units, that these receptacles on rooftops have GFCI (ground-fault circuit-interrupter) protection for personnel. Oftentimes the heating and air-conditioning equipment in a dwelling unit is located in an accessible crawl space under the dwelling unit, which requires a worker to be in contact with the ground while servicing or repair operations are being performed, and shock hazards can and do exist. Section 210- 8(a)(4) stipulates that the required receptacle located in these crawl spaces be protected by a GFCI.

Disconnecting Means Required
Section 440-14 also requires a disconnecting means for air-conditioning and refrigeration equipment to be located within sight from and readily accessible from the equipment location. This disconnecting means is permitted to be located on or within the equipment. This requirement adds considerable safety for the workman servicing this equipment. Service Personnel on a rooftop often may not even know where to begin to find a disconnecting means if it is not located within sight from the equipment location. They  also may not have access to the disconnect if it is located remote from the equipment.

There are two exceptions to the rules in Section 440-14. Exception No. 1 permits a disconnect to not be located within sight from the equipment location with several restrictions. First, the disconnect located in accordance with Section 430-102(a) must be capable of being locked in the open position. Also the air-conditioning equipment must be essential to an industrial process and located in a facility where conditions of maintenance and the supervision ensure that only qualified persons will service the equipment. This exception was a new requirement for the 1999 edition of the NEC. Exception No. 2 allows an attachment plug and receptacle to serve as the disconnecting means in accordance with Section 440-13. This location is required to be accessible, but not required to be readily accessible.

In summary, compliance with the minimum requirements of the National Electrical Code and proper maintenance practices will result in installations that are essentially free from hazards. The main purpose of the Code is the practical safe guarding of persons and property from the hazards that arise from the use of electricity.
