In a recent survey, homeowners said that AC & Heating Connect is a key source of information about air conditioning and heating equipment, second only to friends and family. One of the hottest discussions (pardon the pun) within the air conditioning and heating industry is the difference between two refrigerants – R-22 and R-410A. As a homeowner considering a purchase, it’s important that you understand the difference so you can make the best decision for your system. We’ve outlined below the main differences and why they matter. Often referred to by a brand name like Freon® As of 2010, R-22 was discontinued for use in new air conditioning systems R-22 is a hydro-chlorofluorocarbon (HCFC) which contributes to ozone depletion Often referred to by a brand name like Puron® Has been approved for use in new residential air conditioners Is a hydro-fluorocarbon (HFC) which does not contribute to ozone depletion Will become the new standard for U.S. residential air conditioning systems in 2015

Newer air conditioning models are designed to be used with R-410A for reliable and more efficient operation. Because R-410A can absorb and release more heat than R-22, your air conditioning compressor can run cooler, reducing the risk of compressor burnout due to overheating. R-410A also functions at a higher pressure than R-22, so new compressors are built to withstand greater stresses, reducing the chance for cracking. If you were to put R-410A refrigerant into a system designed for R-22, the pressure would be too much and the unit would break. All air conditioners use an oil to keep the compressor lubricated during operation. R-22 air conditioners use mineral oil and R-410A systems use synthetic oil. The synthetic oil is generally more soluble with R-410A than mineral oil is with R-22. This means the R-410A system operates more efficiently reducing wear and tear on the compressor. While R-22 was outlawed in 2010 for use in new units, some companies are taking advantage of the law by producing what’s known as ‘dry charge’ units.

These are new units that don’t have the refrigerant installed at the factory. Instead, a technician is required to come out to your home and install the R-22 refrigerant. While this practice is technically legal, this isn’t the best option for the following reasons:ahu air handling unit คือ There is a limited supply of R-22 and its price will increase as supplies diminishbmw e46 ac control unit R-410A offers greater efficiency, saving you in energy costs, and is much better for the environmentrecharging rv ac unit Dry charged units typically offer much shorter warranty periods What have you heard about these two refrigerants?

According to the contract, the warranty covered repairs through Aug. 13, 2013, including parts and labor.So when the air conditioner broke last summer, the 95-year-old Lincolnshire resident called the store where she bought the unit, Gleason & Elfering in Wauconda.A technician arrived July 12 and replaced the air conditioner's motor and capacitor. Despite the 10-year warranty, the technician charged Mittl $791.12, which she immediately paid by check.Weeks later, her daughter, Elizabeth Dlouhy, was going through Mittl's finances and discovered the paid repair bill.Realizing the repair should have been covered by her mom's warranty, Dlouhy began calling both Gleason & Elfering and Trane, asking for a refund.On one call, she was told she had waited too long to file a warranty claim, she said. On another, she was told the old parts had to be returned to Trane. And so it went, for months.After Dlouhy called several more times, Gleason & Elfering sent Mittl a check for $152.92, leaving a balance of $638.20.Dlouhy said she was never told why her mother received only a fraction of the repair cost.

Convinced her mom was entitled to the remaining $638.20, Dlouhy sent a letter toWhat's Your Problem?this month."This experience has been akin to an adult version of a Whac-A-Mole game, much to the detriment of the reputation of Trane and its dealer, Gleason & Elfering," Dlouhy said. "Every time I respond to an objection as to why the contract cannot be honored, the dealer or Trane finds another excuse to not reimburse my mother for this warranty-covered expense."The final straw, she said, was when Trane told her the claim was too old."It would not have been old had the claim been promptly processed," Dlouhy said.Last week, the Problem Solver called both Trane and Gleason & Elfering.A short time later, Maria Weber, a spokeswoman for Ingersoll Rand, the parent company of Trane, emailed to say the situation had been fixed."I read through everything again and saw that Ms. Dlouhy's original note to my president went to the wrong address, otherwise we might have seen this case sooner," Weber said.

"We are very sorry that Ms. Dlouhy's mother had an unpleasant experience but believe and hope the issue is now resolved."Karen Lewis, service manager at Gleason & Elfering, said the technician who serviced Mittl's air conditioner in July did not know she had an extended warranty. Had he known, he would have used a Trane motor, which would have been covered.By the time Dlouhy called to inquire about the warranty, it was too late, Lewis said."We had already bought and put the motor in," she said. "We put it through Trane, but because we didn't put in one of their motors," they rejected the claim.Lewis said that after the Problem Solver called Trane, the manufacturer called Gleason & Elfering and offered to throw in another $147.Gleason & Elfering decided to cover the remaining $491.20 and sent Mittl a check for the remaining $638.20."We ended up just eating it," Lewis said. "Long story short, we still service her and we want to keep servicing her." Reports Sought In Jonbenet's Sister's DeathColumbo`s WorldPain relievers: What are the differences?
