Contractors Search for Role in DIY Market

HVAC Contractors Reporting an Increase in Faulty DIY Installation Calls


September 22, 2014

With the availability of hot new items like Wi-Fi thermostats at big-box stores and online retail giants like Amazon, more and more homeowners are choosing to buy and install products themselves rather than go through a contractor. In fact, the do-it-yourself (DIY) smart home market, which the thermostat is indeed a part of, is expected to grow in the U.S. from $1.3 billion today to $7.8 billion by 2019, according to a report by NextMarket Insights.
If this is indeed the trend over the next couple of years, it could present a problem to contractors. Not only would they lose out on a sale, but they could see an increase in service calls over malfunctioning equipment.

The Right HVAC/R Tools Can Drive Field Performance

Originally published: 03.01.14 by Bill Spohn


The typical goal of HVAC contractors and their customers is to extract maximum performance from installed equipment. This makes sense — it’s a goodinvestment, right?
This usually equates to expending the least amount of energy necessary to satisfy the customer. Equipment performance might also relate to efficient use of space or low noise levels. You want to obtain the smoothest operation and highest efficiency possible. Or, you follow this process: right size, appropriate equipment, correct installation, and proper commissioning. If good processes yield good equipment performance, then good job-related processes should yield high productivity, or good field performance. Let’s take a look at a contractor’s work processes as they relate to the tools that are used. Are you performing as efficiently as possible with the right HVAC/R tools? Are your tools and techniques fast enough to get the job done as efficiently as possible? Fast comes in many flavors: let’s cover a few below.

Keeping Productivity High As Summer Ends

What to do if your customers are telling you "I'll wait until next spring."

Keeping your technicians and office personnel productive during a long, hot summer becomes increasingly difficult as the summer continues. By the end of the busy season, the telephone has stopped ringing off the hook, but it still is ringing. Your technicians may not be scheduled for overtime or even for all 40 weekly work hours. Most of the equipment that is going to break has broken and been fixed. Or if it breaks, many times the homeowner's response is: "What do I have to do to keep it running right now? I'll wait until next spring to replace it." He limps along for the remainder of the season.
To keep productivity high, you must plan some end-of-the-busy-season activities. Here are a few that I find most valuable:
  1. Maintain a complete tickler file. (It's critical that you start one, if you haven't already.) For each customer who tells you, "I'll wait until next year," place a reminder note in the tickler file. This will ensure that you call the customer next spring.

Defining The ‘Real’ HVAC System

By: David Richardson

An innocent assumption made by many is that the HVAC equipment is the HVAC system. This has unknowingly turned the specialized skills required to perform HVAC into a commodity in the eyes of many.

If you don’t think this is an issue, think back to the last time you tried to convince a homeowner or building contractor that you are different. Consider how well that is working out for you when you’re selling the Exact same piece of equipment as your competition.

Comparing Motor Technologies

http://www.achrnews.com/articles/comparing-motor-technologies
The heating, ventilation and air conditioning (HVAC) industry currently uses a variety of motor technologies in its equipment. The type specified in any product design depends upon several criteria, including the product’s performance goals, positioning, cost and potential application. Historically, the two predominant motor types have been permanent split capacitor (PSC) single-speed motors and 2.3 electronically commutated motors (ECMs) with variable-speed capability. Most HVAC professionals understand the key differences between these two motor types and are comfortable discussing the benefits of one technology over another.

Man Gets Prison Time for Venting R-22

Ohio Man Pleads Guilty to Violating Federal Clean Air Act

A 35-year-old Columbus, Ohio, man recently pleaded guilty in federal court to violating the Clean Air Act after law enforcement officers witnessed him cutting a refrigerant line on an air conditioning unit and illegally venting hydrochlorofluorocarbon (HCFC)-22, also known as R-22, into the atmosphere. Martin C. Eldridge III now faces 31 months in federal prison for releasing the refrigerant, which is currently being phased out of production in the U.S. due to its threat to the earth’s ozone layer.

While Eldridge’s conviction seems to be an isolated incident, many are hoping it is a sign the U.S. Environmental Protection Agency (EPA) will be cracking down on individual violations across the country.
Caught Red-handed

According to the office of the U.S. Attorney for the Southern District of Ohio, Eldridge and others stole at least 49 air conditioning units between August and October 2013 in order to sell the copper and parts for cash. Randall K. Ashe, special agent in charge of the EPA’s Criminal Enforcement Program in Ohio, said Eldridge’s “continual theft of air conditioner parts was illegal and a clear violation of the Clean Air Act.”

Commander Robert Meader, who oversees the property crimes bureau of the Columbus Division of Police, said his officers actually watched Eldridge cut the refrigerant lines. As soon as Meader was notified of the crime, he recognized it as a violation of the Clean Air Act and contacted federal authorities.

“We had covert undercover personnel following him, and, since he’d hit that particular apartment complex before, they waited for him to cut it,” he said. “Once the hydrochlorofluorocarbon were released, Eldridge violated both state and federal codes.”

Eldridge is serving his federal sentence concurrently with the sentence he received for stealing the air conditioning units. He will require court supervision for a year after his release, and was sentenced to 200 hours of community service.
First Time for Everything

For Meader, this is the first time he has seen an individual convicted of violating the federal law.

“Eldridge now has the notoriety of being the first person charged and convicted in the state of Ohio under the Clean Air Act for stealing air conditioners,” he said. “It’s very difficult to get a charge under that.”

While Eldridge was sentenced to prison time, Meader pointed out he wasn’t the only person to be punished under the law.

“At the time [of his arrest], we had 19 area scrapyards, and seven of the 19 didn’t comply with the federal law, so they had to enter into consent decrees with the EPA,” Meader explained. “If you bring an air conditioner into a scrapyard, as the seller, you have to sign a document saying you disposed of the [R-22] in compliance with federal law; not one of our area scrapyards did that. They also have to have equipment that extracts that fluid, and none of our scrapyards did.”

Meader pointed out that for just one violation, the fine is $39,500.

“They all piped up and said, ‘you have my attention,’” he said. But, even with prison time and hefty fines on the line, Meader wasn’t sure if Eldridge’s fate would necessarily keep others from illegally venting R-22, though he said Eldridge is certainly “going to think twice about doing it again.”
Unusual Enforcement

While it is not unheard of for the EPA to enforce the Clean Air Act, Charlie McCrudden, senior vice president of government relations for ACCA, said violations are usually voluntarily reported to the EPA when a leak is discovered — not reported by the police after a suspect has been arrested.

“There’s a lackluster enforcement of Section 608 of the Clean Air Act,” McCrudden said. “In commercial equipment, with a 50-pound charge or above, if there’s a leak in it, you have to report it to the EPA. All emissions are voluntarily reported, and the EPA takes enforcement action, so they’re not going out and finding violations. But, for residential equipment, there isn’t any police force to make sure they’re abiding by the rules.”

McCrudden said the EPA was able to go after Eldridge for the Clean Air Act violation because local law enforcement officers witnessed Eldridge cutting the line and releasing R-22. However, in most cases where an individual is suspected of illegally venting R-22, the evidence is only circumstantial, which makes conviction difficult.

Meanwhile, it’s the law-abiding and responsible HVACR contractors who are suffering from the lack of enforcement, McCrudden said.

“A lot of contractors, or people who purport to be contractors, are deliberately ignoring these rules; they don’t get trained or certified, and they don’t buy the required recovery equipment,” he said. “That puts the playing field in their favor while the upstanding contractor goes through all the regulatory hoops just to be undercut by these people.”

While McCrudden admitted it is really hard to convict someone for violating the 608 rules, he still hoped Eldridge’s conviction would be “a sign of things to come” for the industry.

Five Ways to Prevent Mold from Invading a Home


August 11, 2014
http://blog.friedrich.com/five-ways-to-prevent-mold-from-invading-a-home/

You may not realize this, but mold is actually a naturally occurring part of nature. If you take a walk in the woods, you will probably see some mold acting as the forest’s recycling system. However, since you probably don’t live in the woods, odds are you don’t want mold in your home either. Here are five ways to prevent mold from infiltrating your home.

old home Address and fix leaky plumbing – Make repairs to leaky plumbing quickly, especially under toilets and cabinets and in the basement where water can collect out of sight. Also check for damp pipes where condensation is collecting. Wipe these dry whenever you find them and then find proper insulating materials to prevent a recurrence of condensation.
Quickly clean up spilled water – After a spill or a water leak, get water wiped up immediately. If rugs or carpets are involved, make sure that they are given plenty of opportunity to dry before being put back in place. Although not technically a “spill,” it will also help to wipe the shower dry after each use.
Keep an eye on your drip pans – Some of our modern conveniences are an unknown source of pooling water. Make sure that drip pans and drain lines from AC units, refrigerators and ice machines are unobstructed and free-flowing so that water isn’t allowed to collect or pool.
Utilize your exhaust fans – Humidity often builds up in the bathroom, kitchen and laundry room.  Make sure that each of these rooms has proper exterior venting, an exhaust fan to the outside, or a window. Sources of humidity:
  • –Cooking/Boiling Water
  • –Automatic Dishwashers
  • –Showers/Baths
  • –Drying Clothes
Purchase a reliable dehumidifier – The indoor humidity needs to be kept low to prevent mold growth, if possible between 30 and 50 percent. The right dehumidifier – like Friedrich’s Energy Star-designated D50BP with built in drain pump – can pull up to 50 pints of moisture from your home’s air every 24 hours. It can handle damp to extremely damp circumstances, uses regular house current and comes with a 6-foot power cord.
