You can ask any business to provide evidence of basic liability contractor insurance coverage. Any company that is not ready to provide proof of general liability (GL) insurance coverage ought to be prevented. A minimum basic for GL insurance coverage is $1 million for property work and $2 million for light commercial.

There are other methods for researching air conditioning, heating and ventilation companies such as: call your regional Better Business Bereau (BBB), carry out online searches and reviews and ask the company in concern for referrals. However, all these techniques fall short of detailed transparency. The BBB really works for the business it represents as they are only rated if the business in concern pays them a recurring cost. Online review sites hardly ever show all the reviews got, and post reviews from sources that are not constantly trustworthy. This provides a platform for business to post their own reviews and people to quickly publish reviews without the business in concern's capability to expertly fix the issue. Furthermore, no company would offer a negative referral; just those that are exceptionally positive. None of these are ideal characteristics for consumers seeking entirely unbiased reviews and references. It is advised to use these methods as an educated customer and think about the info source for exactly what it is worth.

Among the very best methods to discover a new a/c, heating and ventilation contractor is via the "word-of-mouth" technique.

Although these companies do supply a service with some benefit, they are, in reality, including cost to the consumer. Angie's List, in addition to some other online service directory sites, charge the consumer straight for their ratings and companies' contact details. Other third-party sites supply consumers with cooling, heating and ventilation companies and add the cost of being a middle-man to business formula. Bear in mind that none of these are "complimentary" which consumers should comprehend the expense and worth of utilizing entities like these.

Multiple estimates are suggest when hiring an air conditioning and heating specialist. There are no market standards for pricing HVAC associated product or service. Comparable jobs can vary thousands of dollars from one company to the next. A minimum of 3 estimates is advised prior to the repair work or replacement of any significant cooling and or heating system part and prior to the style and installation of new systems.

A second opinion can be of worth if the repair or replacement is costly. Not all service technicians or business are equal or respectable. Repairing cooling and heating systems is extremely intricate. It is not unusual for a repair technician to be not able to isolate the issue or for a representative to recommend an unneeded purchases. Getting in touch with a contending a/c and heating company can conserve money and time and regret.

Hi there...there's a possibility your kitty may have an urinary tract infection. It's not uncommon.

Here's an article by Cornell University College of Veterinary Medicine of Feline Health about inappropriate soiling problems: http://www.vet.cornell.edu/fhc/brochures...

House soiling is the most common behavior problem reported by cat owners. It includes urination and/or defecation outside the litter box, as well as urine spraying.

Why do cats eliminate outside of the litter box?
One common misconception is that cats soil in inappropriate places for revenge. It is tempting to conclude, "He defecated on the living room carpet to punish me for leaving him for the weekend." But this kind of calculation requires sophisticated cognitive abilities that cats aren't believed to possess. Furthermore, this conclusion assumes that cats view their urine and feces as distasteful, when in fact they do not. It is only we humans who view it that way.

Medical Problems
So why do cats urinate or defecate on your bed or carpet? Medical problems are one possibility. Inflammation of the urinary tract may cause painful or frequent urination, inability to urinate, bloody urine, and crying during urination. An affected cat is likely to eliminate outside the litter box if he comes to associate the box with painful urination, or if he has an increased urgency to urinate. In addition, kidney, liver, and thyroid diseases often lead to increased drinking and urination. Inflammation of the colon or rectum, intestinal tract tumors, intestinal parasites, and other gastrointestinal conditions may cause painful defecation, increased frequency or urgency to defecate, and decreased control of defecation. Age-related diseases that interfere with a cat's mobility (for example, arthritis, nervous system disorders, or muscular diseases), or with his cognitive functions can also influence his ability to get to the litter box in time. In short, any medical condition that interferes with a cat's normal elimination behavior can lead to house soiling.

Litter Box Aversions
Behavioral problems, such as litter box aversions, inappropriate site preferences, or urine spraying can also lead to house soiling. An aversion implies that there is something about the litter box that your cat finds unsavory. It could be the box, the litter, the location of the box, or all three.

Cats will repeatedly mark areas where they urinate/spray. Therefore it's important to clean the soiled areas with an enzymatic neutralizer something like Nature's Miracle for Cats. It breaks down urine proteins by soaking the affected areas thoroughly allowing to air dry. Repeated applications are necessary for heavily soiled areas.

Space Air Conditioning?
My Parents Refuse To Get Air Conditioning For The Whole House, Even Though It Gets Up To 98 Degrees In The Summers Here... However, They'Ve Got An Air Conditioner For Their Room. So I'Ve Decided To Ask For An Air Conditioner For My Room For My Upcoming Birthday. I'M Hoping For One 150$ Or Under. Also Not Sure- Do They Make 'Space Air Conditioners' Like They Do Space Heaters? Leave Links For Ones You'Ve Bought And Like Or That Are In My Price Range, Thanks 🙂

There are such things as "portable" air conditioners which do not mount in a window...but they do have to have a hose go out a window, so it amounts to almost the same thing.

Those portables are lousy. They cost way more than a window unit of comparable capacity, are noisier, and have that hose doing its thing. Worse yet, the hose itself is pretty warm, radiating heat back into the room! Portable AC units aren't anywhere near as efficient OR effective as the window units they fail to replace.

My son has a small window unit, just 6500BTU cooling capacity. In his attic bedroom, the room can blow past 100 degrees in the summer before lunchtime; with the AC running, it holds at a steady 75. A comparable unit to the one I put in there is about $125-150. If you want to have a little extra capacity (don't go crazy, too big doesn't work as well as you'd think), offer to go in halfsies.

Gas Smell From My Car'S Air Conditioning?
Yesterday I Was Super Low On Gas In My Car, But It Was Hot So I Turned On My Air Conditioning. A Strong Smell Of Gas Was Coming Through The Vent. I Thought Maybe It Was Fumes Because The Gas Was So Low, I Don'T Know. I Filled Up The Gas Tank And It Still Smelled Like That Until I Got On The Freeway And Was Going Faster. The Smell Seemed To Come Back When I Got Off The Freeway And Slowed Down. Any Idea What Is Going On?

your evaperator core could be leaking, and the smell coming through your vents is pag oil (a strong musty smell) ac lesson!- the evaperator is the component which is loced inside the car's dash. when refregerant cycles through the system it travels through an orfice tube or expansion valve which causes the liquid to evaporate and freeze the aluminum evaporator. then air passes through the evaporator into the car. p.s. it could also be a faulty drain tube which is causing moisture to sit inside the heater case. check the drain tube coming out of the firewall before you get too serious. because evporator replacements are not a small job, the dash actually has to come out of the car to replace it.

Burning Smell From Air Conditioning?
Hi Guys! I Need Your Expertise On This One. I Drive A 2005 Chevrolet Trailblazer (If It Matters...) There Is A Bad Smell Like Burning Coming Out Of My Air Conditioning And It Happens Only When I Turn The Ac On. It Would Also Make A Weird Noise Only When I Turn On The Ac. It Would Make A Weird Noise For Like 2 Seconds And Then Stops Like 6 Seconds And Then The Noise Starts Again. When I Turn Off The Ac, It Doesn'T Make That Sound Anymore. Now, Before All This Happened, My Ac Already Had A Problem For Maybe 2 Or 3 Years Now (And Never Bothered To Fix It) : Whenever I'M Driving The Ac Would Work(Cold Air), But When I Get To A Stop Light There'S No Cold Air. I Wonder If It Has Something To Do With A Symbol I See On The Upper Left Hand Side. I Think Its A Water Pipe Symbol. I Dont Know For Sure... What Do You Think The Cause Is? And Depending On How Bad The Problem Is, Do You Think I Can Still Drive This Car? I Commute, So It'S A 45 Minutes Drive From Campus To Home. Should I Just Drive Home Without The Ac On? What Do You Guys Think????

Please Help Me Interpret &Quot;Postcards&Quot; By Margaret Atwood?
Postcards By Margaret Atwood I'M Thinking About You. What Else Can I Say? The Palm Trees On The Reverse Are A Delusion; So Is The Pink Sand. What We Have Are The Usual Fractured Coke Bottles And The Smell Of Backed-Up Drains, Too Sweet, Like A Mango On The Verge Of Rot, Which We Have Also. The Air Clear Sweat, Mosquitoes & Their Tracks; Birds & Elusive. Time Comes In Waves Here, A Sickness, One Day After The Other Rolling On; I Move Up, It'S Called Awake, Then Down Into The Uneasy Nights But Never Forward. The Roosters Crow For Hours Before Dawn, And A Prodded Child Howls & Howls On The Pocked Road To School. In The Hold With The Baggage There Are Two Prisoners, Their Heads Shaved By Bayonets, & Ten Crates Of Queasy Chicks. Each Spring There'S Race Of Cripples, From The Store To The Church. This Is The Sort Of Junk I Carry With Me; And A Clipping About Democracy From The Local Paper. Outside The Window They'Re Building The Damn Hotel, Nail By Nail, Someone'S Crumbling Dream. A Universe That Includes You Can'T Be All Bad, But Does It? At This Distance You'Re A Mirage, A Glossy Image Fixed In The Posture Of The Last Time I Saw You. Turn You Over, There'S The Place For The Address. Wish You Were Here. Love Comes In Waves Like The Ocean, A Sickness Which Goes On & On, A Hollow Cave In The Head, Filling & Pounding, A Kicked Ear. I Love This Poem. I'M Going To Write My Poetry Assessment Commentary On It, But I Have A Few Questions... In The Last Two Lines Of The First Stanza, What Does &Quot;The Air Clear Sweat, Mosquitoes & Their Tracks; Birds & Elusive&Quot; Mean? And Why Does Atwood Use & Signs Instead Of The Actual Word &Quot;And&Quot;? In The Second Stanza, I Don'T Understand The Whole &Quot;In The Hold With The Baggage There Are Two Prisoners, Their Heads Shaved By Bayonets, & Ten Crates Of Queasy Chicks. Each Spring There'S A Race Of Cripples, From The Store To The Church&Quot; Part.... And Lastly, In The Third Stanza, What Does The Hotel Represent? Thank You ^^

(1) "The air clear sweat, mosquitoes & their tracks; birds & elusive" mean?

About this line, I’m looking at the text of the poem in Atwood’s “Selected Poems II” and it looks like your version leaves out a word. The lines in my text read as follows:

The air clear sweat, mosquitoes
& their tracks; birds, blue & elusive.

That’s a little easier to parse. As you know, in this stanza, the speaker is listing the things that you’d actually find in this setting – wherever she is.

She’s already listed shattered Coke bottles, various ripe tropical smells, rotting mangos. These lines continue the list: the tropical air is like “clear sweat” – hot, sticky – it’s like breathing sweat.

“Mosquitoes & their tracks” – that’s a little harder. I’m not really sure what she means by “tracks.” Maybe the patterns of bites they leave across everybody’s bodies? Like track marks from a needle? Maybe it’s that there are so many mosquitoes flying through the air, you can practically see them carving tracks through the air.

“birds, blue & elusive” – evidently, there are blue-feathered tropical birds there as well, practically invisible against the bright blue sky.

Why does she use “&” (the ampersand)? My guess would be as a gesture towards the writing style of post cards, right? One thing the poem does is shifts in and out of the abbreviated, telegraphic style of post cards and the more fluid free verse reverie style. So the & signals that she’s parodying the post card writing style.

“prisoners … race of cripples ….”

About this section: Atwood’s Canadian. The poem comes her 1981 “True Stories” collection of poems. She probably vacationed in Central America – El Salvador, Costa Rica, Guatemala, maybe even Nicaragua. Panama?

Both of those nightmarish images are part of the reality of life in Latin America. Life is rougher; in general, you’re less shielded from some of the less pleasant aspects of life. So, in the “hold” (or storage area) of the ship that brought here, there very well may have been two manacled prisoners being transported. In the same way, the “race of cripples” could very well be part of a local feast day -- something that happens every year. Attitudes are different in places. (One thing – war, poor medicine and hygiene, horrific working conditions all mean that there are a lot of cripples in any third-world town.)

Think of this section as related to that famous phrase associated with the Sex Pistols’ “Holidays in the Sun” (it was on the dust jacket – not a lyric in the song): “a cheap vacation in someone else's misery."

When you vacation in poor countries, it’s hard to get away from that fact. This is just another aspect (like the smell of sewage and the mosquitoes) of unpleasant reality intruding into her vacation.

The hotel? You don’t have to go super-symbolic with this. Any part of the world with beach property will see periodic overbuilding of luxury hotels. So she’s probably staying in some traditional waterside tropical town – and a new hotel is being built.

The thing is … there are far too many of these hotels. So they’re built and start crumbling almost right away. Investors with a few dollars have a dream of turning a beach property into a tourist hotspot – but generally it’s not going to happen.

At the same time, she’s probably also aware that she’s dealing in some “crumbling dreams” of her own. The dramatic situation of the poem is clearly that she’s writing to someone she’s in a strained relation with. Think of the lines “a universe that includes you can’t be all bad, but does it [actually include you]?” In other words, she’s wondering if the person is even still a part of her universe – is still a part of her life.

She calls her love a “sickness” that comes in waves.

The straight shot is that the postcard is being sent to someone she ended a relationship with? The “vacation” is a way to deal with the pain of ending, to get some distance, a change of scenery. And yet, her desire for this person, her wish to be with him or her – it pounds on her in “waves.”

So at one level, just like the hotel might be someone’s unrealistic dream of a prosperous and luxurious future, she’s having a hard time abandoning her own dreams and wishes.
