Product Liability Lawyers Put Your health and Safety First by Pat Perkins

Defective Product Case History

Let’s just say that the year 2009 is one you would like to forget and it’s not over yet. It didn’t start out badly; in fact, back in January all was wonderful until your 2-year-old home began to reek of sulphur, a smell that lingered oppressively despite cleaning, ventilating and the use of various aroma enhancers and odor cover-ups. At about the same Continue reading Product Liability Lawyers Put Your health and Safety First by Pat Perkins

Hvac Contractor: Commercial Refrigeration

Commercial Refrigeration: What is it?

Refrigeration is best described, as a process, by the removal of heat from a space or substance, thereby cooling it. This process does not refer to the active cooling of a space or substance, but to the extraction of heat, which creates cold. (Artificially creating cold temperatures is formally called cryogenics, not refrigeration.) To begin understanding the complicated, but innovative process of refrigeration, it’s necessary to understand its breakdown-its components. The most widespread kind of refrigeration today is through a vapor compression cycle. The main components are the compressor, the condenser and evaporator coils, and the expansion valve. There is the vapor to be compressed; a compressor to compress it; the condenser coil; the expansion valve; and the evaporator coil. First a gas coolant is compressed. It heats up because of the immense pressure put upon it. Then the very hot compressed gas pass

es through a condenser coil, where it condenses into a liquid. This liquid passes through the expansion valve, where its pressure is reduced and the liquid is cooled through the process of adiabatic expansion. The cooled liquid now goes through the evaporation coil. As air blows over the coil, the refrigerant absorbs heat and cools the air. The liquid boils and turns to a vapor. Because of this evaporation, its temperature can drop to as low as -27 degrees Fahrenheit. The vapor recycles into the compressor to begin the process anew.

The basic purpose of refrigeration is not to keep perishable foods cold. Keeping them cold is the means to the end, and that is to slow the growth of bacteria on the food. This is what preserves perishable food: The retarding of any organic growth that could begin to break down food, thereby making it inedible. Now it takes longer for food to go bad, which means a significant increase in shelf life. If a bottle of milk were left on a counter at room temperature for two or three hours, it would surely sour. But milk can last two to three weeks under refrigeration. Food stays fresher longer. That means more food is for sale longer.

Who it’s for:

A great number of foods are perishable. Without the aid of refrigeration, store owners and restaurateurs would be extremely limited to a small number of foods to serve or sell. Bananas, apples, pears, oranges, peaches, and other fruit; meats, cheeses, eggs, and milk; sauces, gravies, and dips are a small group of the many foods that a proprietor in the food business would want to refrigerate. But the uses of this necessary modern technology extend to the vintners’ world, too. Reducing the temperature of wine can prevent yeast from continuing to grow and carbon dioxide from evolving. Therefore the wine remains largely intact as the vintner meant it. It will not become more alcoholic. It will not take on properties of carbonization that would otherwise undermine the integrity of the vintage.

Its benefits and disadvantages:

Refrigeration prolongs the life of a various number of important foods. Without this process, these foods could quickly yield to the destructive forces of bacteria and decay. Contemporary refrigeration systems use refrigerant compounds that contribute either slightly or not at all to the depletion of the ozone layer. These are hydro chlorofluorocarbons (HCFCs)-which contribute to a lesser degree to ozone depletion, and hydro fluorocarbons (HFCs)-which do not contribute to ozone depletion. Before the widespread use of these compounds, chloro fluorocarbons (CFCs) enjoyed popularity. But CFCs contribute significantly to ozone depletion. Even though HCFCs and HFCs tend not to threaten the health of the ozone layer to the extent of CFCs, they still maintain what is called Global Warming Potential, or GWP. When choosing a refrigerant to use in your commercial refrigeration unit(s), keep in mind two serious factors. One is the “direct effect,” or the immediate impact the refrigerant could have on the surrounding environment or atmosphere if it leaks. Secondly, think about the amount of energy necessary to operate your refrigeration system. Overall, HFCs are the optimal compound. They are largely energy efficient, contain low levels of toxicity, and they can be reused. They have a high rating of what’s called “Life Cycle Climate Performance” (LCCP). In the case of HFCs, low LCCP means they consume low levels of fossil fuel, and thus they are responsible for low levels of carbon dioxide emissions, a key factor in manmade greenhouse gases

Getting a new furnace can be a difficult task. When it comes to furnaces there are several different types of systems and options to choose between. While a good contractor will help you find the right furnace you also want to do your own research to make sure you are making an informed decision.

Efficiency Level

The Annual Fuel Utilization Efficiency or AFUE is used to rate most furnaces. The AFUE measures how much heat is delivered to your house in comparison to the amount of fuel that you need to give to the furnace. For example, an 80% AFUE rating means that 80% of the fuel you supply is used for heat while the other 20% is lost through the chimney. However, the AFUE will only tell you the fuel efficiency of the furnace and not the electrical usage.

As of January 1, 1992, the US Department of Energy determined that all furnaces need to have a minimum of 78% AFUE to be sold in the United States. Most furnaces have an AFUE rating of 80%, but high efficiency furnaces can have an AFUE as high as 90%. If you live in cold weather, areas the higher the percent rating the more money you save during cold winter months.

Choosing a Location

When choosing where to place your furnace the area in which you live plays a major role. For those in colder regions the best option is a gas or oil furnace or boiler. For those in a warmer region it may be a better choice to use a gas furnace or heat pump. If you don’t have a gas or oil service where you live then you may need to choose an electric heating system such as electric furnaces or heat pumps. If gas is available, but you home doesn’t have it then you may want to talk with a plumber about installing a gas line. Although if electric costs are cheap in your area then an electrical system can be a better choice. The best form of advice is to talk with a reputable HVAC contractor in your area. However, because of the low cost in most areas a natural gas furnace or boiler can be a good idea.

Heat Exchangers

When it comes to gas furnaces the most expensive and important part is the heat exchanger. Typically, a separate parts warrantee covers this part. This warranty typically covers five years, but some can be as high as ten to twenty years.

Choosing a Thermostat

If you aren’t home during certain parts of the day, it can be a good idea to consider getting a programmable thermostat. This way you can set your unit to a low temperature when you aren’t home and then have the house return to a comfortable temperature at a certain time before you arrive home. This also allows you to set temperatures different for when you are asleep and when you are awake. Many programmable thermostats can be set by the week so you can easily program it for specific days when you are home and those days that you aren’t home.

Duct Installation And Repair Hvac Contractor

When you hire a duct installation and repair HVAC contractor, you’re taking an important step to maintaining your indoor air quality as well as the integrity of your heating and cooling duct systems. This is very important for all of us. Although there are no set guidelines as to the frequency that your air duct system should be serviced, most manufacturers of heating and cooling systems have a clause in the warranty that they provide stating that you must have your duct systems serviced at least once a year.

Of course, if you are having a new home built or if you are remodeling an older home, you recognize the need for duct installation. What most people fail to realize though, is that heating and cooling duct system repairs and maintenance are vitally important for all family members. The important letter in HVAC is the “V”. The V stands for ventilation. Ventilation has a whole lot to do with the air that we breathe. And the air that we breathe is our primary life force.

1000

Here are just a few of the advantages and benefits to be gained from hiring the services of the right duct installation and repair HVAC contractor:
By keeping your heating and cooling duct systems well maintained, you significantly reduce the amount of the following air pollutants present in your home’s immediate atmosphere: Pet hair and dander; Tobacco smoke; Pollen; Mold spores; Dust that damages your lungs; Dust mites; Bacteria and viruses that cause disease;
You keep your heating and cooling unit’s warranties from being voided;
You keep your entire system for indoor air quality functioning smoothly and in a problem-free fashion;
Your entire family has a lower probability for the development of allergies and other health issues;
Your house, carpet and furnishings are kept cleaner from dust, dirt, bugs and other pests;

It’s very important to think about the fact that you are constantly breathing in and out. Every day, all day long, you are allowing air pollutants to enter what should be your pristine respiratory system. Every negative pollutant that you allow to enter into your system is a potential for sickness. It is estimated that most people spend as much as 90% of their time inside of their homes. Ensuring a high level of indoor air quality is of profound importance.

Other services offered by a duct installation and repair HVAC contractor:

Installation of attic fans that accommodate the following: Removal of excessive top-level heat buildups in your home; Removal of various air pollutants that may stagnate; Significant reductions in cooling bills;
Air duct cleaning:
Highly pressurized air washing;
Furnace cleaning;
Installation of air exchangers;
Cleaning of transit air ducts;
Cleaning of housing units;
Chimney cleanings;
Fireplace cleanings;
Cleaning wood stoves;
Installation of chimney caps;
Applications of germicide fogs to destroy all mold, mildew, mites and bacteria;
Dryer vent cleaning;
Refrigerator coil cleaning;
Furnace A-coil cleaning;

Making sure you hire a reputable duct installation and repair HVAC contractor:

It’s very important to ensure that the contractor you hire to install and/or maintain your heating and cooling duct systems is a tried and true professional that operates with meticulous levels of conscientiousness. Here are a few tips to ensure that:
Go with your gut when you speak with or meet your potential HVAC contractor. Let’s face it; there are a lot of crooks in the world. You don’t desire to hire one of them to work in your home in any regard. If you have warning signals going off about the potential character of the contractor that you are interviewing, move on to the next one.
If he or she hasn’t already offered it, ask for a list of references – and then check them;
Most contractors worth their weight will offer you a photo portfolio of jobs that they have completed;
Check with the BBB (Better Business Bureau) and inquire as to any complaints lodged against this contractor;
Inquire whether the contractor that you’re speaking with will actually be on-site during the installation and/or maintenance procedures. Many times, the professional-looking and smooth-sounding contractor that you speak with or meet is certainly not the same person that shows up to do the work.

The bottom line concerning duct installation and repair HVAC contractors:

There’s no doubting that quality installation and maintenance of your heating and cooling duct systems is very important. The benefits are numerous and very necessary as well. In
1000
fact, the health of your entire family in part depends upon it. What you need to make sure of is that you are dealing with a well-established, quality HVAC contractor that will deliver superior service before, during and after the actual installation or repair work takes place. Take your time and make the right decision in hiring the best HVAC contractor to meet your needs.
