HVAC systems for all your needs

IHVAC means heating, ventilation, and air conditioning. It is a system used to provide heating and cooling services to buildings. Before the creation of this system, the three elements were usually split between three or more devices. Nowadays there are numerous different HVAC systems available to any potential client. Some have been used for a very long time while some are brand new inventions yet to become as widespread. No matter what type of HVAC you decide to purchase you should make sure that you buy it from the right company. Presented below are some of the HVAC systems you might wish to have installed in your home. Radiators are an old-fashioned way to keep your family warm. Invented in the mid-1800s, it has evolved over the years into the low-maintenance, energy-efficient heaters that we know today. There are two main types of radiator heaters that you should know about — electric and steam. Steam radiators work by boiling water to create steam. That steam then travels up a set of pipes into the radiator, which in turn, heats up the room via radiation and convection. As the steam travels through the unit, it slowly cools down and turns into condensation. This condensation then goes through the unit, ending its travels back in the boiler, where it is ultimately turned back into steam. There are a couple versions of steam radiators that you could choose from, if you’ve decided that this is your preferred heating method. The oldest version of a radiator heater - the cast-iron system - is very efficient at heating up the room. However, it also takes up the most amount of room, and takes longer to heat up. Despite these two obvious downsides, the way it’s designed allows the cast-iron system to also hold that heat for the longest period of time. Baseboard steam systems take up very little room in your home. You can run them along the baseboards of your home in a very discreet manner. A ceramic system is the newest version of a steam radiator. Unlike its predecessors, it’s not hot when you touch it and it’s more efficient at supplying sustainable heat. If you were going to choose a steam radiator to heat your home, this would be the one you should look for. Electric radiators are built in similar fashion as a steam radiator; however they utilize a different method of creating heat. At a radiator heater’s core is a metal reservoir filled with a special mineral oil. At the bottom of the heater is a heating element similar to what is found within an electric stove. It is electrically powered and is used to heat up the oil. Once the oil is heated, the warmth is convected throughout the body of the heater, warming its walls. The heat is then conducted through the metal walls and radiated into the surrounding space, filling the room with wonderfully cozy warmth. Radiant heating systems supply heat directly to the floor or to panels in the wall or ceiling of a house. The systems depend largely on radiant heat transfer -- the delivery of heat directly from the hot surface to the people and objects in the room via infrared radiation. Radiant heating is the effect you feel when you can feel the warmth of a hot stovetop element from across the room. When radiant heating is located in the floor, it is often called radiant floor heating or simply floor heating. It is more efficient than baseboard heating and usually more efficient than forced-air heating because it eliminates duct losses. Radiant heating does not distribute allergens making it an attractive option for people with allergies. There are three types of radiant floor heat -- radiant air floors, electric radiant floors, and hot water radiant floors. The air cannot hold large amounts of heat, so radiant air floors are not cost-effective in residential applications, and are seldom installed. Although they can be combined with solar air heating systems, those systems suffer from the obvious drawback of only producing heat in the daytime, when heating loads are generally lower. Electric radiant floors typically consist of electric cables built into the floor. Systems that feature mats of electrically conductive plastic mounted on the subfloor below a floor covering such as tile are also available. Hydronic (liquid) systems are the most popular and cost-effective radiant heating systems for heating-dominated climates. Hydronic radiant floor systems pump heated water from a boiler through tubing laid in a pattern under the floor. In some systems, controlling the flow of hot water through each tubing loop by using zoning valves or pumps and thermostats regulates room temperatures. A furnace works by blowing heated air through ducts that deliver the warm air to rooms throughout the house via air registers or grills. This type of heating system is called a ducted warm-air or forced warm-air distribution system. It can be powered by electricity, natural gas, or fuel oil. Inside a gas- or oil-fired furnace, the fuel is mixed with air and burned. The flames heat a metal heat exchanger where the heat is transferred to air. Air is pushed through the heat exchanger by the “air handler’s” furnace fan and then forced through the ductwork downstream of the heat exchanger. At the furnace, combustion products are vented out of the building through a flue pipe. Heat pumps are simply two-way air conditioners. During the summer, an air conditioner works by moving heat from the relatively cool indoors to the relatively warm outside. In winter, the heat pump reverses this trick, scavenging heat from the cold outdoors with the help of an electrical system, and discharging that heat inside the house. Almost all heat pumps use forced warm-air delivery systems to move heated air throughout the house. No matter which system you will choose, Global Heating & Cooling is certain to provide you with high quality services and products.

HVAC maintenance and repair

HVAC systems are among the most essential elements of a safe and comfortable life in your home. Properly taking care of them will allow you to prevent your power bill from needlessly growing as well as ensure your comfort during both hot and cold weather. One of the ways you can take care of your HVAC system is by regularly changing or cleaning the air conditioning filters. Some filters can be washed and reused, while others are disposable. Whatever type of filter you use, it helps if you have several spare ones at home so you can instantly change them at the right time. Basically, you will want to change your dirty filters once every 2 months or more frequently if you use your heating and cooling systems for longer hours. This is extremely important to prevent clogging in the filters where dust, debris and other air particles are trapped. Over time, these can accumulate and clog your filters; thus, preventing smooth airflow. As a result, your system will have to work harder in order to efficiently distribute warm or cool air throughout the house. This can drastically increase the power usage in your house and therefore increase the power bill. Besides the air conditioning filters, you should also clean the air ducts. If they are not cleaned regularly they might get clogged with dust and debris. Help your your heating and cooling system - make it easy for them to operate. This can be done by making sure there are no gaps in your windows and doors where the cold or warm air can escape. You can also help your heating and cooling system maintain the cold or warm temperature inside the house by not frequently opening doors and windows. Also, try not to let sunlight in while you are cooling the house as it can heat up the house quickly and make it difficult for the system to maintain cold air. If your household has a programmable thermostat, turn down the heat at night, or when the family is out during the day, then raise the thermostat settings for the morning and evening hours. Try to keep thermostat temperatures steady for best comfort and energy savings. However, HVAC systems require regular professional maintenance. Schedule such visits before the weather changes. You'll have the service technician's full attention if he's not forced to respond to numerous emergency calls after the first hard freeze. You definitely want him to have the time to properly inspect your HVAC system. To ensure that he does a good job you should hire only the reliable HVAC companies in Chicago. A good example of such company would be the Miron Heating & Cooling, Inc. Every HVAC contractor employed by them is highly experienced and highly trained. They will take care of any problem you might have with your HVAC system. While some HVAC issues are simply a matter of cleaning the coils and filters, something that you can do yourself, many of the most common heating and cooling system problems can develop into much bigger concern if not serviced early. Most of these can be avoided with regular preventive maintenance calls. There are a number of mechanical components your heating system relies on. Your unit's performance can be negatively impacted by normal wear and tear of these components. These include belts and bearings, which may result in overheating, poor heating, or airflow issues. Regular maintenance should include checking for worn or stretched belts and oiling bearings and motors if necessary. Both air conditioners and high efficiency furnaces produce condensate. Drain pipes are employed to ensure proper water drainage. Furnaces can leak water if the drain lines are either clogged or cracked. A homeowner can help keep the drain lines clean by pouring bleach down the drain periodically. Other possible leak sources could be the collector box, heat exchanger or evaporator drain pan. A service technician should be contacted to determine the source of the water leak and repair options. HVAC systems can lose efficiency and cause a significant increase in your monthly heating or cooling expenses. This happens because the system works harder to make up for the loss by running more often. If you've seen a sudden spike in your energy bills, that can't be explained by increased use or weather-related issues, you should have your HVAC system checked by a professional. If your HVAC system develops strange noises you've never heard before, or if the noises it usually makes are louder than usual, that could be a sign of serious trouble. However, first make sure that the noises aren't due to loose components, unfastened doors or access panels, or other parts that produce rattling, banging, or clattering noises. Squealing or screeching noises could mean that a fan or other moving part needs to be lubricated. They can also indicate that a fan belt needs to be changed. If a gas furnace develops internal popping or banging sounds, it could mean that gas is building up and is burning off with a sound. This could eventually become a significant problem and should be checked out as soon as possible. If your HVAC system won't work at all, the problem can often be traced back to the thermostat. Many modern programmable thermostats run on batteries, and if the batteries run down, the thermostat will go off and the HVAC equipment will not run. Check the screen of the thermostat, and if it's blank, put in new batteries. This is one of the most common HVAC problems, and usually thermostat will come back on and the HVAC system will work like normal. If battery replacement doesn't solve the problem, the thermostat itself may need to be replaced. A tripped circuit breaker could also be the cause of a non-functioning HVAC system. Breakers can be tripped because of power surges in the electrical lines. An occasional breaker trip shouldn't be a cause for alarm, but constant issues with the breaker could indicate a significant problem. Reset the breaker and the system should work again.
