You can ask any company to offer evidence of basic liability specialist insurance. Any business that is not ready to provide evidence of general liability (GL) insurance coverage should be avoided. A minimum basic for GL insurance is $1 million for residential work and $2 million for light industrial.

There are other methods for investigating a/c, heating and ventilation companies such as: contact your regional Better Business Bereau (BBB), perform online searches and reviews and ask the company in concern for recommendations. However, all of these methods fall short of comprehensive transparency. The BBB actually works for the business it represents as they are only ranked if the company in concern pays them a repeating charge. Online review websites rarely show all the evaluations got, and post evaluations from sources that are not always reputable. This offers a platform for business to publish their own evaluations and individuals to hastily publish evaluations without the company in question's capability to professionally resolve the concern. Furthermore, no company would provide an unfavorable recommendation; just those that are incredibly positive. None of these are ideal dynamics for consumers seeking totally impartial reviews and recommendations. It is advised to use these methods as an informed consumer and consider the info source for exactly what it deserves.

One of the best methods to find a brand-new a/c, heating and ventilation professional is via the "word-of-mouth" technique. If the company advised was budget-friendly, expert and reliable for a buddy or family member, there is a great opportunity that company will do the exact same for you. Excellent business use the word-of-mouth method to continuously provide a new client stream by keeping their clients delighted.

Other traditional methods for discovering a new a/c, heating and ventilation specialist include carrying out online searches, phonebook directory sites or online directory sites and other ad mediums. Bear in mind that of these techniques are purchased and spent for by the companies in concern. None of these techniques must act as a testimonial and ought to be utilized just as finding sources.

3rd party companies such as Angie's list, Discover Regional and other online companies are the latest platforms for sourcing and rating air conditioning, heating and ventilating business. Although these business do provide a service with some benefit, they are, in reality, adding expense to the consumer. Angie's List, as well as some other online business directory sites, charge the client directly for their rankings and business' contact details. Other third-party websites supply customers with air conditioning, heating and ventilation business and include the cost of being a middle-man to business formula. Bear in mind that none of these are "free" which customers need to understand the cost and worth of utilizing entities like these.

Numerous estimates are advise when hiring an a/c and heating specialist. There are no industry requirements for pricing HVAC related service or products. Similar tasks can vary countless dollars from one business to the next. A minimum of three quotes is recommended prior to the repair or replacement of any significant air conditioning and or heater element and prior to the design and installation of new systems.

A consultation can be of value if the repair or replacement is expensive. Not all professionals or companies are equal or respectable. Repairing a/c and heating unit is incredibly intricate. It is not uncommon for a repair work specialist to be unable to isolate the problem or for an agent to recommend an unneeded purchases. Calling a competing air conditioning and heating business can save money and time and remorse.

Frequently Asked Questions:

What Small Animal Can Live In A Studio Sized Apartment Which Is Air Condition?
I Am Looking For A Small Animal That Can Keep Me Company While I Am Studying But I Don'T Want A Cat Nor A Dog. I Want Something Small That Is Maximum As Big As A Ferret But I Don'T Want Any Reptiles In The Apartment Cause I Don'T Want To Feed Insects Or Mice. I Have Fishes (Beta) But I Am Looking For Something A Lot More Cuter And Fun Too Play With. And No Insects. I Also Want An Animal Which Can Live In An Air Conditioned Room.

Well ferrets are awesome. Playful like a puppy forever. Believe it or not Rats make good pets too. They love to sit on your shoulder and groom your hair. Sugar gliders are marsupials and look like flying squirrels. They love to be with you and are very interactive. Rabbits and guinea pigs are good too but they aren't as interactive. You could also try birds like zebra finches, parakeets, and cockateils. But they can be loud at times and they like to rip up bedding and usually throw food out of their feeding bowls.

How Do Mice Get Into Your Home Return Air Vent?
For The Past Two Winters, I Have Noticed That Mice Are Nesting In One Of My Return Air Vents. I Don'T Have Central Air Conditioning So I Don'T Know Where The Vent Goes Out? The Mice Can Be Heard In The Basement Up To My 2Nd Floor Bedroom Return Air Vent. Apparently, They Can'T Or Don'T Come Inside The House Because I Have Never Seen Not One Dropping Inside My House And I Have Set Traps But Nothing. How Can I Find Out How They Are Getting In? And Why In This Area? I Have Sealed Up All Noticeable Holes Around The Inside And Outside Of The House And Low And Behold They Come Back To That Same Area. This Puzzles Me To No End, They Are Just In That One Area. There Must Be A Way They Get In From The Outside. My House Is 78 Years Old And I Don'T Even Know Where My Return Air Vents Goes Out To. Help?

In many older homes return, and sometime supply, vents were "panned" which is basically saying that they used the floor joist or wall frames to make paths for the air to travel in.
Because these Pans are interconnected throughout your home, the entry point for the mice can be anywhere.
Today's codes while still allowing panning in certain circumstances, they require the panned bay to be ducted. This not only cuts down on your house guests but also some of the nasties that find the environment in an unlined panned joist a beautiful breeding ground.
Spring time comes around, consider having a professional duct cleaner work on your home. Many, using newer technology can actually send small remote cameras through the system identifying blockages, unwanted openings (Or were you intending on heating the attic with that duct?), and other potential issues.

What Size Central Air-Conditioner Do I Need For My House?
I’M Interested In Getting A Central Air Conditioning System Installed. How Do I Determine What’S The Correct Size Air Conditioner For My Home?

Let the HVAC contractors size it properly for you and guarantee their work. Call 3 companies and let each size, price and explain why they selected that size. Sizing should include performing heat/coooling load calculations. Do not let them use just square footage alone,

Make sure each is licensed, insured and check with thelocal BBB

Which Psychrometric Process Or Process Are Used In Air Conditioning Systems?

In the domestic and industrial air conditioning applications some psychrometric processes have to be performed on the air to change the psychrometric properties of air so as to obtain certain values of temperature and humidity of air within the enclosed space. Some of the common psychrometric processes carried out on air are: sensible heating and cooling of air, humidification and dehumidification of air, mixing of various streams of air, or there may be combinations of the various processes.

Illustrating and analyzing the psychrometric properties and psychrometric processes by using the psychrometric chart is very easy, convenient and time saving. In the next few paragraphs we shall see some of the most commonly employed psychrometric processes in the field of HVAC and how they are represented on the psychrometric chart.

Sensible Cooling of the Air

Cooling of the air is one of the most common psychrometric processes in the air conditioning systems. The basic function of the air-conditioners is to cool the air absorbed from the room or the atmosphere, which is at higher temperatures. The sensible cooling of air is the process in which only the sensible heat of the air is removed so as to reduce its temperature, and there is no change in the moisture content (kg/kg of dry air) of the air. During sensible cooling process the dry bulb (DB) temperature and wet bulb (WB) temperature of the air reduces, while the latent heat of the air, and the dew point (DP) temperature of the air remains constant. There is overall reduction in the enthalpy of the air.

In the ordinary window or the split air conditioner the cooling of air is carried out by passing it over the evaporator coil, also called as the cooling coil. The room air or the atmospheric air passes over this coil carrying the refrigerant at extremely low temperatures, and gets cooled and passes to the space which is to be maintained at the comfort conditions.

In general the sensible cooling process is carried out by passing the air over the coil. In the unitary air conditioners these coils are cooled by the refrigerant passing through them and are called also called evaporator coils. In central air conditioners these coils are cooled by the chilled water, which is chilled by its passage through the evaporator of the large air conditioning system. In certain cases the coil is also cooled by the some gas passing inside it.

The sensible cooling process is represented by a straight horizontal line on the psychrometric chart. The line starts from the initial DB temperature of the air and ends at the final DB temperature of the air extending towards the left side from high temperature to the low temperature (see the figure below). The sensible cooling line is also the constant DP temperature line since the moisture content of the air remains constant. The initial and final points on the psychrometric chart give all the properties of the air.



Sensible Heating of the Air

Sensible heating process is opposite to sensible cooling process. In sensible heating process the temperature of air is increased without changing its moisture content. During this process the sensible heat, DB and WB temperature of the air increases while latent of air, and the DP point temperature of the air remains constant.

Sensible heating of the air is important when the air conditioner is used as the heat pump to heat the air. In the heat pump the air is heated by passing it over the condenser coil or the heating coil that carry the high temperature refrigerant. In some cases the heating of air is also done to suit different industrial and comfort air-conditioning applications where large air conditioning systems are used.

In general the sensible heating process is carried out by passing the air over the heating coil. This coil may be heated by passing the refrigerant, the hot water, the steam or by electric resistance heating coil. The hot water and steam are used for the industrial applications.

Like the sensible cooling, the sensible heating process is also represented by a straight horizontal line on the psychrometric chart. The line starts from the initial DB temperature of air and ends at the final temperature extending towards the right (see the figure). The sensible heating line is also the constant DP temperature line.

Who Replaces Air Conditioning And Coolant Hoses?
I'Ve Been Having Some Problems With My Car. It'S A 2001 Ford Taurus And It'S In Pretty Good Condition Except Lately Its Hoses Have Been Leaking. The Coolant Hose Leaks Really Bad, Also My Air Conditioning Has A Hose That Leaks Freon (Sp?) Faster Than I Can Put It In. Since It'S Nearly Summer Here In Louisiana, I Want To Fix My Ac! So Who Do I Take It To To Have The Hoses Replaced?

take it to your mechanic, or a dealer.

Most anyone can fix coolant hoses (radiator). Air conditioning refrigerant is a HAZARDOUS material, Special equipment need to add/change/dispose of the liquid.
