That doesn’t have to be your story. You do have options. Instead of being baked alive inside the house, arrange for an emergency air conditioning service to come by. Such companies generally provide service after traditional business hours, on holidays and weekends, and when time is of the essence. Several emergency HVAC service and repair companies are in business. However, the optimal time to look for a company to handle your emergency A/C needs is not when you find yourself stuck in an awful situation with the air conditioner out of commission. Instead, save yourself the frustration and start looking for a company that you can rely on in an emergency now, while everything is still alright.

When looking for the emergency service and repair company that you want to do business with, be certain to ask about the experience and training of the technicians. Be certain to ask especially about the experience of the technicians that are usually on call overnights, holidays, and weekends. Some companies give their newest, and often most inexperienced technicians the most unfavorable shifts. Others provide these shifts to the most experienced and efficient technicians.

Ask about fees while you are shopping around. Some companies charge based upon the time that the technician spends in your home while others charge based upon the job. From a consumer’s point of view, there are positive and negative aspects to both methods of billing. Though the method of billing is not generally of utmost importance, it is advantageous to be aware of how billing is handled before an emergency strikes.

Finally, be certain to ask if the technicians have experience working with your air conditioner’s model. A/C units are like cars; just because someone is capable of fixing one type of unit does not mean that person is qualified to fix a different type of unit. In residential settings, technicians are usually able to repair all models, though it is always best to ask.

The ventilation of a building should be considered from the very beginning, ideally during construction. Unlike other aspects of an air conditioning system, the ventilation system is nearly impossible to make major changes to after construction. Any changes would require that the entire building be reconstructed. Therefore, early consideration of ventilation needs is essential to avoid costly and time consuming repairs and changes later on.

Ideally, a ventilation and HVAC expert will be called in for consultation during the construction planning of a building to ensure that the proper ventilation system and control strategies are utilized from the very beginning. Many contractors believe that this is an unnecessary expense, but it should strongly be considered if at all possible. Once a building has been constructed, the ventilation system must be properly maintained, just like the air conditioning system. Providing maintenance and upkeep for the A/C unit, yet forgetting about the ventilation system, can yield incredibly disturbing results. A faulty ventilation system can be far more time consuming and costly to repair than a faulty A/C unit, mainly due to the need to reconstruct an entire building to make major changes to the ventilation.

Ensuring that the staff that repairs and maintains the HVAC system is also qualified to care for the ventilation system is the best way in which to avoid major repairs. It may mean high costs associated with the wages of the technicians, but it is very much worth it. A ventilation system must be surveyed at least monthly, though weekly is ideal. During the survey, the technicians should be checking for any possible obstructions. Obstructions are the most common causes of problems in building ventilation. Ironically, they are also the most easily prevented problems. Clogs are commonly the result of external factors, such as animals and weather. Birds are notorious for building nests in duct and ventilation systems, thereby causing lots of problems. Constant surveying of the duct and ventilation will allow a technician to recognize that a problem is occurring before it grows too large. Sweeping the ducts of the ventilation system, in much the same way that a chimney sweep gets rid of the soot in a chimney to maintain an unobstructed chimney.

Not only is building information modeling useful when constructing a new building, but it is also useful after the building has been constructed. For example, if the owner of a building notices that there is a water leak in the building, the building owner can take a look at the information modeling program to see where water valves are located in the building. This would prevent the entire building from having to be surveyed and would cut down on the time involved in the diagnosis and repair of the problem. If there is adequate information available in the modeling system, the building owner would also be able to locate all of the pertinent information regarding the water valve, including pieces of information such as the model number.

There has been a major push to acquire building information modeling systems for previously constructed buildings. The benefits would be plentiful, though the costs could be outrageous. Some people believe that the benefits outweigh the cost and others disagree. Therefore, building information modeling systems are not readily available for previously constructed buildings.

The Associated General Contractors and other contracting firms believe that BIM systems have greatly improved the world of building construction. Most contractors believe that building information modeling greatly reduces the costs associated with the construction of a new building by reducing the amount of time required to perform the construction. In August 2004, the National Institute of Standards and Technology confirmed that the use of building information modeling systems did, in fact, save time and money when constructing a new building.

Though the use of building information modeling can be greatly beneficial to contractors, some contractors find it to be more of a hassle than it is worth. This is typically due to the software requirements associated with building information modeling. This is generally regarded as an uneducated view given the extreme amounts of time and money that building information modeling system have been shown to save contractors once they learn how to use it. However, those contractors that do not find building information modeling systems to be beneficial usually claim that having to upgrade all of their software is not beneficial for their individual situations.

Overall, most people would agree that BIM systems are greatly beneficial and would like to see their use even in previously constructed building. However, the software requirements make this a wish that probably will not be granted in the near future, though they will likely be growing in popularity for initial construction. Soon enough, the use of building information modeling with be truly commonplace in the construction industry and will be used even for previously constructed buildings.

BACnet Module
The BACnet Module allows for optimal communication regarding the system. Monitoring and diagnostic work regarding the system can be communicated through this two way communication system, making relaying information about the system much more efficient than with any other rooftop system. Not only does the BACnet Module cut down on time spent repairing the unit, but it also helps to make it a more efficient unit by ensuring proper communication and maintenance.

Independent Motor Mount
The independent motor mount allows for easy access to the motor. The top panel does not have to be removed in order to access the motor, unlike many other models. This is ideal because it saves lots of time when performing maintenance and repair of the system. Time saved when performing maintenance can be used for other needs, thereby also saving tons of money associated with maintenance and repairs.

High and Low Pressure Switches
The high and low pressure switches are an amazing safeguard measure that the Strategos rooftop unit has. It safeguards the compressor from operating conditions that would cause damage. Though the use of these switches are optional with these units, it is highly advised that these switches always be enabled. There is virtually no reason not to utilize these switches. These switches work in a similar fashion as switches on a circuit board. This feature can save lots of money in costly repairs that are avoided when the switches prevent damage.

Slide Out Blower Deck
The slide out blower deck greatly improves a technician’s access to the belt, motor, and blower. This reduces the amount of time required to properly perform maintenance. In an industry where time is money, this is a feature of the Strategos rooftop unit that should not be overlooked. Time saved inspecting, replacing, and repairing the belt, blower, and motor can be used to care for the rest of the rooftop unit, thereby making this one of the most notable benefits of this unit. Ensure, though, that the time saved is used to ensure maintenance of the entire rooftop unit to ensure that the unit continues to function properly.

Filter Driers
The filter driers protect the rooftop units from moisture and dirt that would otherwise collect. These driers cut down dramatically on the amount of maintenance required for these rooftop units. Other units require much more maintenance because of dirt and debris that collects due to the absence of a filter like this one. Though this filter may seem as though it takes all of the work and problems out of a rooftop filter, this is not quite the case. Much of the work and problems are completely removed, but proper maintenance and upkeep still need to be performed.

Public schools tend to have the greatest amount of concerns in regards to their A/C systems. This is mainly due to their funding coming from the public dollar. Therefore, justifying HVAC upgrades can be quite an uphill battle. This is why it is important to consider the needs of a public school in Florida before the school is built. It is much easier to convince the public that additional funds are needed during construction than after the school has been built.

Maintenance and repair of public school HVAC systems in Florida is another concern that must be addressed. Ideally, the school district will hire a group of technicians to ensure that the A/C systems are properly maintained. Though school is typically out of session during the summer months when the A/C is working its hardest, it is important to remember that the schools will still be in use. Therefore, maintenance must be performed year round in order to ensure the proper functioning of the HVAC system.

Private schools are generally smaller in size than public schools. Therefore, the capabilities of an air conditioning system for these schools generally do not need to be as great as the capabilities of an A/C unit for a public school. However, that does not mean that maintenance should be neglected. Quite the opposite is the case. Small problems in small HVAC units and duct systems can lead to major issues. Therefore, even private schools should have technicians on staff to ensure the proper upkeep and maintenance of its A/C system.

Air conditioning units in Florida must be especially rugged. Though Florida is known for its beautiful weather and stunning beaches, Florida’s weather can be unpredictable. Hurricanes and hail are not uncommon during Florida’s summer months. Therefore, an A/C unit in Florida must be built well in order to withstand the weather that it may have to endure. When shopping for an HVAC system for a Florida school, it is imperative that one look specifically for systems intended for hot, humid, and unpredictable climates.

Maintenance for air conditioning systems in Florida should be performed twice as frequently as air conditioning systems in other parts of the country. This is due to the extreme amount of use that these systems endure year round. Unlike A/C systems in other parts of the country in which the air conditioning is only in use for three to four months out of the year, systems are used in Florida an average of eight to eleven months out of the year. This increased usage increases the amount of wear and tear.

Many people do not service their air conditioning units as frequently as needed, especially in Florida. Typically, people think that it is either a waste of time, a waste of money, or both. Nothing could be further from the truth. Performing adequate routine maintenance will save monumental amounts of both time and money in the long run. Routine maintenance can be planned in advance to fit in nicely around a busy person’s schedule. Problems that occur as a result of lack of maintenance tend to strike with a moment’s notice and are generally much more costly to repair than the total cost of maintenance that should have been performed. HVAC systems behave similarly to any other mechanical device, such as a car. Everyone knows that putting off an oil change for too many miles will result in a disaster and incredibly costly repairs. The same concept holds true with an HVAC system.

Many Florida-based companies choose to hire technicians onto their staff to take care of all of the maintenance that is required. In most cases, this is the best route to ensure proper maintenance. Additionally, it allows minor problems to be corrected right away before they turn into major problems that are costly both in time and financial resources to rectify.

When hiring staff to handle the care of the HVAC system is not an option, many companies in Florida hire an outside company to perform the necessary maintenance and repairs. When searching for a company to handle these issues, be prepared to shop around for a company that has technicians that will be able to meet your system’s needs. Be sure to ask about the company’s service and repair hours. Ask if they have a technician on call for evening, holidays, and weekends. Don’t feel the need to overlook a company that is a quality company and simply does not have any service available after traditional business hours. A variety of companies exist that offer only emergency services and make an excellent back up plan. Be certain to look into a back-up plan for emergencies before an emergency strikes. The time to be looking for a repair technician is not when the temperature is in the triple digits and the A/C unit suddenly stops working. It’s much less stressful for everyone involved to have that information available ahead of time so that no one has to search frantically through the phone book in an attempt to find a quality repair service at a moment’s notice.

Today’s ductwork consists of insulated flexible tubes that snake across the attic floor or under the house. Unfortunately, heating ducts are out of sight and often out of mind. Homeowners wouldn’t put up with leaking water pipes. But ductwork — carrying air instead of water — can leak for years, without anyone knowing it. Water damage is immediate, but the only reflection from poor ductwork will be increased heating and cooling costs.

Ducts can leak – anything that punctures a duct will cause lost air. This could be as simple as a protruding nail or staples used to hold the duct together. Then, too, joints and junctions where two pieces of duct come together may separate over time – especially if duct tape was used to seal them. Contrary to the name, duct tape is not very good at sealing ducts together. It fails in very hot and very cold conditions. It is better to use a mastic – a viscous sealant that is painted on.

Builders sometimes even forget to attach ductwork together or to connect it to the vent in the wall. As a result, an open duct wastefully pumps conditioned air into the attic or under the house, while the room it is supposed to serve never gets comfortable.

Poor air flow in an HVAC system also occurs when ducts are blocked or kinked. Just as a pinched garden hose cuts down the flow of water, a kinked duct drastically reduces the flow of air. Kinking can happen when ducts are run along tight corners, or into tiny spaces… Make sure ducts are properly supported, and don’t sag, twist or bend overmuch, and they have no gaps or breaks.

Design is important as well. Ducts that are too small for the volume of air are improperly designed. A duct that is too large in one room may leak conditioned air that should be going do a different room in the house. The air conditioner or heater may be either undersized or too large for the duct system, providing too little or much more pressure than the system was designed to handle. Often, builders may try so skimp on materials and use whatever they have in stock, instead of ordering the correct specified equipment.

If its duct system is poorly designed or poorly installed, a house will be inefficient, no matter how well insulated it may be, or how perfect its furnace and air conditioner are. That’s why it’s a good idea to have your duct system examined for leaks, blockages, and just poor design. Air conditioning companies familiar with duct testing can perform the examination, and your local utility may give you a sizable rebate when you have it done. You may be amazed at the monetary savings and the dramatic increase in comfort.

There are many causes for poor air flow in an HVAC system. While many of them are correctable, it takes time and effort to find the problems, as ducts are one of the more hidden aspects of an HVAC system.

The best thing about these rooftop units is the simple fact that they do not cause a lot of disturbance or noise pollution. Units located on the roof are much quieter, as any sound or vibration has to travel through ceiling insulation in order to reach the inside. On top of that, these rooftop units do not use nearly as much energy as other units do.

Most people today are replacing the old rooftop units with HVAC units that run more efficiently, filter the air better, and cost much less. When these are placed in medical facilities or sterile buildings, the air quality can be controlled and monitored to reduce humidity, and remove harmful bacteria or allergens from the general airflow of the building.

Those who are looking at purchasing new rooftop units do need to look at the maintenance that is involved, as well as the other costs that you can expect during upkeep. On top of the thousands that you may spend on the units, you will need seasonal maintenance as temperatures change. Summer and winter are when the air conditioning and heat will need to be utilized the most, but having your system checked in spring and fall can ensure that everything is in order before it’s required.

In some states there are cash vouchers and incentives that you can receive when you do decide to utilize rooftop units for commercial buildings. Depending on the budget that you currently have, you could even get a few discounts or coupons. The bottom line is, these HVAC units are perfect when you need to clean up the air and make living and working more comfortable. If tenants are not happy in the apartment they are living in because of the rooftop units, you may have a hard time finding new renters. There is also no time to waste with poor air filtration when it comes to medical and sterile facilities. This is the last place you want chemicals or bacteria moving through the ducts into clean rooms.

Rooftop units for commercial buildings can be purchased online and can be installed in a wide variety of areas, including apartments and smaller business buildings. The installation should always be done by a professional. An HVAC system is a huge investment, and a lot of variables can affect the price you pay for energy each month. By doing it yourself, you risk an inefficient system that will cost you much more in the long run.

After the installation process is complete you will then be able to enjoy fresh, clean and climate controlled air. All systems can easily be managed anywhere in the building with the thermostat. Do not waste anymore time, cut down the pollution in the air and the pollution in your commercial building by replacing that old rooftop unit. The sooner you find a replacement that saves more energy, the sooner you could be saving money.

When it is time to upgrade your HVAC system to newer technology, there are several things to keep in mind to make the purchase worth the investment. Your initial step should be a total situation evaluation. What does your company have now? What is your end goal for this overhaul? How much is in the budget for a new HVAC system? While these seem like obvious concerns, it is important to take complete control of the situation from the beginning. Overspending defeats the purpose of money saving systems, but not spending enough may leave you with an inadequate system. Just remember, some of the initial costs will be offset by energy savings that are acquired over the life of the system.

You must also gather up to date information regarding your commercial building. Renovations and other changes will have altered your thermal loads. Some changes may reduce your needs. This will allow for the purchase of a smaller system, equaling more energy savings for your business. Take note of all of the energy efficiency changes your building has undergone over the years. General maintenance should have sealed any leaky ducts. Low emissive windows and reduced lighting levels will also allow for the purchase of a smaller HVAC system.

Technology advances every day, promising new and more energy efficient equipment. New heating, ventilation and cooling systems use less energy while providing better air conditioning abilities. Occupant comfort will increase and energy bills will decrease. The correct upgrades are really a win – win situation for all who choose to implement them. Just remember that the most effective changes are the ones that are thought out properly. Stick to your budget and seek out expert advice to buy the correct size HVAC unit for your commercial building and begin reaping the benefits immediately.

As research and development continues to progress on HVAC systems, the outlook looks promising in the field of chiller systems. These systems are created to be used in larger commercial buildings. Combined, heat and power (or CHP) systems are also looking like a viable option. These systems are revolutionary. They use the buildings waste heat to cool the atmosphere. This capability will lessen the energy bill greatly. Some estimates promise a reduction of up to 30% or 40%. The end goal for this technology is to combine the new systems into packages and put them on the market. Keep abreast of technology trends and implement them when the time is right.

Routine maintenance will keep potential problems at bay. It will also keep down your energy costs. Your heating, ventilating, and air conditioning (HVAC) system requires yearly care if it’s expected to run efficiently and keep your home feeling comfortable without any problems. A seasoned contractor should make preseason check-ups each year. When scheduling your appointment, remember that the need for HVAC contractors peak in the summer and fall, so routine maintenance should be booked in the spring or fall for more prompt service.

When your HVAC contractor shows up for routine maintenance, there are a few things that he or should always check. First of all, the thermostat settings need to be checked properly. Without a working thermostat, your system will not be able to properly keep your home comfortable. A working thermostat will also maintain the correct temperature, helping to keep down your heating and cooling costs.

During routine maintenance, the contractor should also tighten the electrical connections in the system, as well as ensure that the proper voltage is flowing in the motors. Without this system check, bad connections are bound to occur, creating an unsafe environment and shortening the length of time your unit will work. System controls should be checked over, as well. A complete inspection of the condensate drain is required. The contractor should also lubricate all parts so that friction is lessened. If friction occurs, your system will require more energy to operate.

There are certain check points that only apply to specific functions. For example, heating components that are not properly taken care of can become fire hazards or cause other potential health dangers. On top of that, any problems that are not rooted out and corrected will ruin the efficiency of your system, ensuring higher energy bills each month until the problem is rectified. In order to stop these issues from occurring, your contractor will overlook all the heater’s connections, burners, and heat exchangers.

Your cooling system is not immune from problems, either. In fact, it has a few more necessary check points for your HVAC contractor to look over. All blower components need to be checked to ensure that the proper air is flowing. Problematic airflows can lead to a 15 percent reduction in efficiency. The evaporator and conditioning coils also need attention. They should be thoroughly cleaned because a dirty coil hinders your systems cooling capabilities. In order to compensate for the lack of cooling ability, the unit will work longer and harder, adding to your energy costs. Refrigerant levels should be maintained, as well. Too much is as bad on the system as too little, and both reduce efficiency levels.

There is one thing you can do yourself to help increase your unit’s efficiency. Replace your filters monthly.
