Frequently Asked Questions:

What Are Some Federal, State, Local Agencies That Write Regulations For The Hvac Industry?
I Am Doing A Compliance Report On The Hvac (Heating, Ventilation, And Air Conditioning) Industry. I Need To Identify Several Federal, State, Local Agencies That Write Regulations For This Industry, But I Have Only Found One Which Is The Epa (The Federal Environmental Protections Agency) Do You Know Any Others???? Please Only Serious Answers! 10 Points!

On a national level the EPA is a major regulator of the refrigerant (cfc, hcfc, hfc) side of the trade and a good place to start as you've figured out. A lot of the mechanical side falls under building code regulations by the ICC (International Code Council); this code would dictate how equipment is installed. NEC (National Electrical Code) also known as NFPA 70 governs how electrical systems are installed, this includes the electrical (line voltage and control voltage) wiring that HVAC equipment utilize. When it comes down to it there really isn't a set of regulations on a national/federal level that regulates or oversees if HVAC equipment is in compliance or not. It's more a combination of building, plumbing, electrical codes that are all taken into account. The EPA is the only regulatory body that sets any type of standards for HVAC and their scope of regulation extends far beyond just refrigerant regulations. OSHA dictates safety regulations on a federal level and is typically adopted on local levels nationally.

Keep in mind though that these federal regulations are usually adopted, amended, or rejected by individual states based on what the local state municipality sees fit. In Washington State there isn't an HVAC license or anyone who regulates the industry in general; what we have in WA is Labor and Industries who regulates or enforces OSHA mandates, NEC regulations, building codes, etc and so on. In addition to state mandates and regulations affecting the HVAC industry, local municipalities such asc counties and cities may enforce licenses, regulations, and what not. Seattle for example requires a City of Seattle Refrigeration license with a initial test and a renewal every 2 years for an individual to work in the city limits within the industry, however outside of Seattle in the state of WA a refrigeration license is not required

A second example would be Ohio; they do have a regulatory board that oversees compliance in the HVAC industry and they are known as 'Industrial Compliance and Labor'. They regulate a lot of what was mentioned in WA but they have also taken it upon themselves to set a standard for the HVAC industry in their state. What you'll find though is that a lot of those regulations are pulled from other regulatory bodies that have been dictated by national bodies.

Hopefully this steers you in more the direction you were looking, the problem with it though is that there isn't a full on regulatory body on a federal level overseeing the HVAC industry as a whole like Plumbing or Electrical codes do. The industry is very fluid and highly dependent on the type of HVAC work you do as well as the region/state/city that you do it in.

What Causes A Central Air Conditioning Unit To Freeze Up?
I Have A Central Air Conditioning Unit That Is Probably 12 Years Old Or So.I Recently Had A Situation Where My Central Air Would Run Constantly Without Shutting Off.The Air Temperature In My House Was 80 Degrees And It Was Still Running.Well,I Also Recently Found Out That The Coils In The Ac Unit Were Completely Frozen Solid Along With The Hoses That Ran From Outside At The Unit,All The Way Inside To My Furnace.Id Like To Know What Causes These Coils And Pipes To Freeze And How Does One Keep It From Happening Again?

"what causes a central air conditioning unit to freeze up?"

Every once in a blue moon, cold temperatures lead to things freezing. Is there something that may be causing cold temperatures in or around your A/C? That may be the problem.

"Id like to know what causes these coils and pipes to freeze and how does one keep it from happening again?"

Again, sometimes it's that cold weather... maybe put it next to your heater and crank it up all the way?

Why Does Air Conditioning Make The Air Feel Colder Than The Temperature Would Seem To Indicate?

Air conditioning also removes the humidity from the air, which is what gives warmer air its oppressive feeling. So, even if the air conditioner doesn't drop the temperature much, it will feel cooler due to the drop in humidity. The lower humidity also allows you to sweat more easily and cool yourself more efficiently, which you can't do when it is higher.

How To Fix The Air Conditioning?

It all depends on what is wrong with it. You might be able to fix it if the problem is the blower fan or its' speed switch, but if anything under the hood has a problem, you should have someone who knows what they are doing fix it.

Thick Glass Bottle Or Thin Glass, Which One Is Good To Keep Hot Water Max Time In Air Conditioned Room?
I Want To Keep Hot Drinking Water In My Air Conditioned Office Room For Max. Time. So, Should I Use Thin Glass Bottle Or Thick Glass Bottle Ie. Liquor Bottles For Max. Efficiency?

If the interior dimensions of two bottles are the same and are made of the same type of glass(i.e.,have thermal conductivity) the thicker bottle will keep the water warmer longer. If the interior dimensions change multiple variables are changing (volume, surface area) and there is no longer a simple answer.
