Ehlers is proud to be a Carrier dealer and top HVAC company in the Livonia, MI area. “Company Rep Eric asked what I expected out of a new Carrier system. He then explained how each component works together to meet... I am quite shocked that every store in my very large metropolitan area that sells HVAC supplies requires purchasers to have HVAC contractors license. Which makes it very difficult for a very technically inclined DIY-er to do the job himself. I understand this is not a DIY and more of a legal question but I am trying to understand why that is. It is as though the Home Depot required an electrical license to sell you a spool of Romex or a receptacle, which they don't.

It is clear that HVAC stores have no intrinsic economic incentive for such a policy; it must come from either the municipal government or their insurance company. Or some nefarious ultimatum from HVAC trade unions so they secure more grip on the market. Their insurance may lean that way. Rates are probably lower if they are not selling to end-users. They may also not have to deal with sales tax, if they are not selling to end-users. As for the (or more) economic incentive many take for granted: the cost of customer service. The below consumes valuable man-hours and to staff this could double payroll: They may also prefer dealing with competent licensed professionals, because they will have less time wasted on "dumb questions" (there are such things, really, even if you've been told otherwise) and irate "genusies" who bought the wrong thing for the wrong job and want a refund because it didn't work, or because they are used to getting "free rentals" by exploiting big-box-store policies that allow them to return things even after they have used them.

The competent licensed professional also provides them with a repeat/regular customer base - how often do YOU buy an air conditioning system? How many do you buy per year? Do you buy parts by the case? Less of their time spent moving more product is more profit for them, even if they sell it at a discount to the professionals (which is common, based on volume.) There is also a concern about the proper handling and recycling of refrigerants - few if any homeowners own a vacuum pump, much less a refrigerant recovery system. There are websites that sell various things (I happen to have been looking at mini-split system heat pumps recently) but you still need a licensed installer to assemble them; both for legal reasons (EPA) and practical ones (that vacuum pump, etc.) In many cases, you'll do better to just buy the system from a local installer than to buy it online and then pay an installer to assemble it for you. This is due to a sales restriction by the EPA. The logic behind the ban is to minimize the risk of releasing ozone depleting refrigerant into the atmosphere.

If you plan to work on HVAC systems fairly often (e.g. if you manage a lot of properties), then you could look into getting yourself certified (it may be a simple as taking some night classes at a local community college). For the average homeowner, it's better to call in a pro since they not only have the certification to get the refrigerant, they also have the various tools to safely use it (manifold gauges, vacuum pump, etc). From the EPA link above: What does the sales restriction cover? This sales restriction covers all CFC and HCFC refrigerants contained in bulk containers (such as cylinders, cans or drums). blends containing HCFCs (such as FRIGC FR-12, Free Zone, Hot Shot® or R-414B, GHG-X4 or R-414A, Freeze 12) are also covered under this sales This sales restriction does not cover refrigeration and air-conditioning equipment or components containing an ozone-depleting refrigerant (such as components of residential split systems containing HCFC-22, also called R-22).

Nor does the restriction cover the retail sale of air-conditioning and refrigeration appliances containing CFC or HCFC refrigerants (such as window air conditioners). However, as of January 1, 2010, EPA banned the import and production of air-conditioning and refrigeration appliances and appliance components that are pre-charged with R-22. More information on EPA's rule banning the sale of pre-charged appliances and appliance components is found here. EPA has previously banned the sale and distribution of refrigeration and air-conditioning appliances containing CFCs (such as R-12), under the Nonessential Products Ban. What type of certification is required to purchase The following people can buy any type of ozone-depleting refrigerant under this sales restriction (for instance, R-11, R-12, R-123, R-22), except for "small cans" containing less than 20 pounds of R-12: Technicians certified to service stationary refrigeration and

air-conditioning equipment by a Section 608 EPA-certified testing Employers of a Section 608 certified technician (or the employer's authorized representative) if the employer provides the wholesaler with written evidence that he or she employs at least one The following people can buy refrigerant found acceptable for use in a motor vehicle air conditioner (MVAC), including "small cans" containing less than 20 Technicians certified to service motor vehicle air-conditioners by a Section 609 EPA-certified testing organization. I don't think this is entirely true anymore. Most HVAC suppliers in my area allow "consumers" to buy from them. There is usually a song and dance to be done. For instance anyone can sign up on several large retailers that sell lots of stuff to HVAC techs, electricians, plumbers and so on. We know the big names. What you do is register yourself as a technician. They don't ask you to provide proof that you are what you say you are.

They let you use your home address as your office address and bam you can order anything. This works on most big websites. I have bought every conceivable piece of HVAC equipment. I still use an HVAC tech depending on the job. If it is a simple replacement with no mods I might do it - I have to figure out if me spending a few hours reading about the swap is worth the price of said tech. If it is a change and involves inspection I often get the equipment - or at least bargain knowing how much it costs - and do as much setup as I can and let the pro take over. I have a couple HVAC guys that will come by any day to do an odd job. What consumers need to understand is that they need to make money. They make good money from me because they give me a discount but their 4-6 hour job is 2 hours because everything is prepped. Also they don't need to bring a helper out and pay that guy. But to answer the question consumers can buy this stuff now and there are a ton of outlets to do so.

Even if you go with what your HVAC guy has, at least you can be informed. I remember the first time I got an air conditioning unit it was a good $400 less than the lowest quote I got from any local business. I was fine paying the "full install cost" and then the next time I called same business their prices were much more in line (still a tiny higher) with what I could get.I'm an HVAC technician, and I don't want you doing your own work. Every job you do yourself takes money out of my pocket. I'm not going to buy supplies from a guy who sells to the public, so most suppliers aren't going to bite the hand that feeds them. The supplier is going to make much more money from me than from you, so guess who they're going to sell to? Secondly, I'm on all the boards and panels that matter. I make sure laws and ordinances that help me pass, and those that potentially hurt me fail. I'm an HVAC technician and have been in the field of HVAC for 32 years now and can tell you there are reasons for restricting refrigerant sales to just anybody, and why you need training before you decide anybody can do this.

For one get some R22 somehow and charge your system. Do you know how much you're adding? Do you know if there's a leak in the system? If there is a leak and you just start charging the system you are venting refrigerant back to the atmosphere. Did you know this is punishable by a $20,000 fine and up to 5 years in prison? If you have a system, let's just say 410a, how do you charge this? Do you have the correct gauges? If you hook up some standard R22 gauges to a 410a system you might find out you don't have a face any longer. For your own safety you need to be certified in refrigerant. If you buy a system on line don't be surprised when you get it that there's no warranty and the charge has been removed. I hope you understand what a vacuum pump is and how to work it as well. Bottom line: just because you are some engineering expert or doctor doesn't mean you know how to do this. Get some 410a oil on your skin and see how smart you are. Stand in a space with no ventilation while you're soldering 410a and the heat was too high and some 410a starts leaking out.
