Hard start kits: improving energy efficiency after installation

Kickstart_grpby Farhang Biek

Even modern air conditioning units may not be as efficient as they can be because of the elimination hard start devices installed at the factory.  In the past all single-phase A/C, heat pump, and refrigeration compressors were equipped with hard start devices at the factory. Several years ago, manufacturers decided to discontinue that practice for most air conditioners and heat pumps in an effort to reduce costs.

A typical start-up requires four to eight times more current to actually start the compressor than what’s required to run it. With this burst of power comes a surge of heat that accompanies the electrical current. This heat damages the compressor, the terminals, the windings and run capacitor.

However, efficiency can be improved for compressors with the installation of a hard start kit. A hard start kit consists of a mechanical potential relay and a start capacitor that is wired to the A/C and heat pump compressor to aid its startup with maximum efficiency so reaching normal rated speed at up to ten times faster than compressors without hard start device.

During start-up, a typical compressor without a hard start device has an electrical efficiency rating of less than 50%. The compressor has to work much harder and is exposed to a lot of excess heat that is generated with each and every start. With a hard start device installed, the electrical efficiency is boosted to more than 98%, enabling all of the available power to reach the compressor for smooth and fast starts.

The benefits of installing a hard start device are:

  • Extend the life of compressors considerably by bringing them up to full speed much more quickly and efficiently.
  • Assist compressors in starting under very harmful ambient conditions such as low voltage, high head pressures or undersized wiring.
  • Reduced “light flicker” during compressor start-up
  • Lower electric bills for the home owners

The average life of Hard Start Devices is generally 5-7 years or 500,000 starts. Most of hard start devices currently come with a two (2) year warranty.

RectorSeal is Gold Winner | ACHR News 2015 Dealer Design Awards

RectorSeal is Gold Winner in ACHR News 2015 Dealer Design Awards

mighty-bracket(Houston, TX)  – RectorSeal was recognized for excellence in product design in the  12th annual Dealer Design Awards Program sponsored by The Air Conditioning Heating & Refrigeration News magazine. An independent panel of contractors acted as judges in the contest that had 107 entries. The company’s Mighty Bracket was the Gold Winner in the miscellaneous category. The ACHR News is the leading trade magazine in the heating, ventilating, air conditioning, and refrigeration industries.

News Publisher Mike Murphy stated, “These awards give us a unique opportunity to recognize the outstanding research and development efforts that go into many of the products serving the HVACR industry and the awards issue gives our readers an opportunity to read about innovative installation and service solutions.”

The reason we came-up with the idea for the Mighty Bracket was because are continuously improving the mini-split installation process for contractors and we saw a lot of two-man installations and installers setting indoor units on top of ladders while they wired-up the equipment.  The actual idea for the product came from the bits and pieces of information which contractors gave us during feedback when we asked them what would make their job of mini-split installations easier, faster or safer.  They couldn’t tell us specifically what they needed or wanted, but we figured it out.  It’s like Steve Jobs said about designing products by focus groups “A lot of times, people don’t know what they want until you show it to them.” 

Once we started working on it, we knew that the eventual product would be a big hit if we made it durable and versatile.  We field tested it with almost all of the new models from major equipment manufacturers to make sure we didn’t miss anything and to get new ideas for any necessary adjustments or improvements to help optimize the design.  

One of the interesting things which surprised us was that installers wanted the product to be a bright color, for safety reasons – – especially on commercial jobsites – – so we made it yellow.

Another great feature that we are hearing that contractors love is toughness of the product, while being so lightweight; it holds-up to rough handling in the service truck and it doesn’t break or get damaged easily if dropped. 
The main and still greatest feature of the Mighty Bracket, of course, is that it now allows the mini-split installation to become a ‘one-man job.’  After all, THAT is why we introduced it in the first place.

The Mighty Bracket has been one of the most successful product launches we have ever introduced to the HVAC/R market!  Our philosophy is “Power to the installing contractor!”

How to market tamper-resistant locking caps for refrigerant access ports.

capsTamper-resistant locking caps for air-conditioning refrigerant-access ports have become integrated into many HVACR service contractors’ service call routines in the last five years.

While some service contractors have not used them yet, a growing legion employ innovative ways of marketing locking caps to the public. Some do it as community goodwill, a profit maker or a combination of both.

The 2009 International Mechanical Code (IMC) initially introduced locking caps to inspectors and contractors when it mandated them on all newly installed units. The mandate aimed at reducing the troubling uptick of teen air-conditioning refrigerant-related huffing deaths in the last decade. The escalating price of R-22 during its current Environmental Protection Agency (EPA) phaseout and the resultant rash of stolen refrigerant appearing on the black market brought yet another reason to lock air-conditioning refrigerant ports.

Now, the 2015 IMC—which will be adopted into most state, county and city jurisdictions during the next few years—calls for a locking-cap installation on any system opened for servicing. San Antonio, TX is one of the first major metropolitan areas to apply the 2015 IMC.

More Manufacturers Adding Ductless to Product Offerings

S-_MG_4918With year-after-year double-digit growth and a projected compound annual growth rate (CAGR) of more than 14 percent between 2013 and 2020, opportunities in the ductless market are sprouting like May flowers.

“It’s, without question, one of the fastest-growing segments in North American HVAC,” said Tom Lahutsky, senior product manager, Lennox Intl. Inc. “The market is very competitive. There are a lot of different solutions out there from some very good suppliers. This growth, which means more units are being shipped, pulls all the manufacturers in.”

Lennox is one of many companies updating its product portfolio in an effort to keep up with the accelerated progress of the sector.

“The ductless market will continue to grow. We don’t see any end in sight for it,” said Lahutsky. “We’ll continue to invest in this area and update our products.”
