  • Do I need an air handler?

    Sometimes the number of components that make up an HVAC (heat, ventilation and air conditioning) system can seem overwhelming. Part of the reason is that HVAC systems are extremely flexible. You can pick only the components you need to heat and cool your business or home as efficiently as possible. In some cases, this involves buying an air handler.

    An air handler has a simple task, to take in air and send it around the home or business. Air handlers often include blowers, heating and cooling systems and filters. It handles much of the “ventilation” port of the HVAC system. Air handlers are commonly used in conjunction with air conditioners. The evaporator coil in the air handler can remove additional heat before sending the air throughout the house.

    Am I in the right climate for an air handler?

    An electric split system for air conditioning in a warm climate, like Florida, will benefit from an air handler. Working in tandem with the air conditioner, the air handler keeps the air cold and blowing.

    However, air handlers can also be beneficial in slightly cooler climates. They can contain both heating and cooling elements. The cooling element would be the evaporator coil, which removes excess heat from the air. Heating elements, like electric heating strips, can also be included in an air handler. In this case, the air handler adds additional heat to the air before blowing it around the home or business.

    While beneficial in cooler climates, air handlers are not as commonly found in cold truly climates, like Minnesota. A gas or electric furnace is commonly used in place instead. Pairing a heat pump with an air handler is typically not sufficient to warm a home or business in a climate that repeatedly drops below zero. A gas or electric furnace is a more effective way to heat the location.

    How do I select an air handler?

    If you live in a warm climate, where the combination of an air handler and air conditioner or heat pump provides sufficient heating and cooling, it's time to look at air handlers. The first step is to do a load calculation, which determines how much heating or cooling is required for the home or business. A Manual J calculation is standard and the most accurate, but rules of thumb can also be applied. The resulting number is the tonnage size of the HVAC system that you ought to purchase for the best efficiency.

    The next item to evaluate is what type of refrigerant the air handler uses. The most common types are R-22 and R410-A. Newer HVAC systems typically use the R-410A refrigerant, which is generally accepted as the more environmentally friendly and efficient refrigerant.

    Air handlers can also be sold with heating elements. This may or may not be necessary in your climate. If your home does not already have heat pump, the heating elements may be a good choice to warm the air in your home when it gets a bit chillier. The heating elements can also work in tandem with a heat pump for greater efficiency. It depends on the system you select for your climate.

    If you need any help determining if your home or business would benefit from an air handler, you can check with an expert or call National Air Warehouse at (888) 997-5160 for assistance.

  • Top Reasons to Pay Attention to your Heating System During the Summer?

    Heating System Heating System

    In every season, you should expect to have HVAC maintenance carried out in order to have your cooling and heating system working efficiently. Bear in mind, though, it does not mean that you have to focus your attention on your air conditioner unit in the summer months and the heating system in the winter. It is important to take the appropriate care of your HVAC system throughout the whole year so that it will always operate to its full capacity.

    Summer Preparation

    Yes, you may be hanging out on the beach during the summer and a heater is the farthest thing from your mind. Yet, you cannot wait until the winter is upon you before taking care of your furnace or other heating system. The season may arrive and that is when you discover problems with your heating system. It is better to approach a season, being confident that everything inside your home is working properly. Below are some of the top reasons why you cannot afford to neglect your heater during the summer.

    Don’t Regret Your Decision

    If you need to have a heater repair done as the winter comes to a close or if the heater is providing warning signals of malfunction, you may need a new heater. For this reason, you should not ignore the signs. If you don’t take immediate action, you may regret your decision. You should not wait to schedule a repair at the last minute. If so, you may be put on a waiting list and who wants to go through winter without a functional heating system? The HVAC technician needs time to inspect the situation and conduct the necessary repairs so that you can be comfortable during the winter months.

    Advanced Maintenance

    One of the things to prevent being an uncomfortable situation is putting your HVAC maintenance on a schedule with a HVAC contractor. Therefore, try to have a healthy heating system at all times by frequent maintenance. There are various tasks that are involved with furnace maintenance and some of these include cleaning dirt and dust, inspecting the air flow, lubrication of moving parts, and thermostat testing. Doing this in the summer makes you prepared for the winter.

    Heat Pump

    Heat pumps are generally used both in the winter and in the summertime. If you do not have your heat pump repaired, then the choice will also affect your air conditioner unit. You will be switching your system to cooling during the summer, but that doesn’t mean that you should completely ignore any heating issues until the winter.

    Proper Ventilation

    Both heating system and cooling system utilize the same ventilation to function, especially when your system uses forced air. For this reason, you have to keep the air ducts clean, not only to improve air quality, but also to prevent this from negatively impacting your HVAC system’s efficiency. When you have problems with your heating system, it can also result in an increase in your summer’s energy bill.

    Conclusion

    Be sure that you change your air filters on a frequent basis, even during the summer. Contact a HVAC contractor or HVAC technician today to schedule an overall check on your heating system and cooling system.

  • A Look at HVAC Maintenance for Each Season

    HVAC Maintenance HVAC Maintenance

    One of the poignant facts in life is that nothing is perfect and that includes your HVAC system. One day, everything may begin to fall apart. Therefore, landlords and homeowners alike have one main responsibility and that is to make sure that the tenants or family members can live inside the building comfortably all throughout the year. What does this mean? It means that your home or apartment will be kept cool during the warm months and whenever you need to have air conditioning unit turned on.

    The Truth

    One more regrettable truth about this is that HVAC maintenance and repair needs to have specialized expertise and skills as well as necessary equipment that many homeowners and landlords do not have. For that reason, you are going to need the services of a HVAC repair contractor. The trick about saving money is to schedule an appointment with a HVAC contractor as soon as possible. You cannot procrastinate, but you must know when to make that phone call.

    Do Not Procrastinate

    If you wait too long, or until the AC system is broken, then you may have to wait for weeks or days to get the contractor to come to your home. Remember, these specialists are always busy serving other clients. Below are some suggestions on when you should call the technician so your system can run smoothly all year round. Let’s look at the different seasons.

    The Summer Time

    During the summer, you will definitely need your AC. It is important to get preventative maintenance done during the spring so that you don’t encounter any problems during the summertime. If your air conditioning unit is running, but it is not doing so efficiently, you may want to have the air filters changed and get rid of dust in and around your AC unit. Otherwise, you should solicit the services of a HVAC technician to see what the problem is.

    During the Fall

    As summer ends, the temperature will begin to drop. This is the ideal time to contact an HVAC contractor to inspect your heating and furnace system. The goal is to try to apply preventative measures prior to waiting until issues arise. Furnaces are like any equipment. They need frequent tune up. This is the perfect time, too, to ensure that you have enough filters for your furnace and that they are changed as needed.

    Winter Weather

    There are not many things that are more risky and uncomfortable than to be inside a home with no heat during the winter. While you may have had preventative maintenance done on your heating system, something can still go wrong. Make sure you have the phone number of a reputable HVAC technician that you can call on a moment’s notice.

    The Springtime

    A reasonable time to contact an HVAC contractor is in the middle of spring. At this time, the contractor will look at your HVAC system to see what kind of preventative measures need to be performed. The HVAC contractor may conduct a check and balance on your refrigerant levels, replace filters and clean your system.

    Conclusion

    Lucky for homeowners, most of the HVAC problems can be fixed. However, these problems will usually need specialized skill. Always include your HVAC contractor when heating and cooling system issues arise, no matter the season.

  • Comparing Packaged and Split Air Conditioner System

    Air Conditioner Unit Air Conditioner Unit

    You may own an air conditioning unit in your home or business, but might not understand how it operates, especially when it comes to receiving savings on energy. What exactly is all this talk about split air conditioner, you may be wondering? Well, a split unit depends on the amount of space that is available in your house. The split air conditioner unit consumes more space; let’s say than the packaged air conditioning unit. This does not mean that you would fare better with the packaged air conditioner.

    The Structure

    The structure of the house has to be in question when choosing the right air conditioner unit. The most common choice for many homeowners is the split air conditioning system. Simply put, the two main categories of central air conditioners are packaged air conditioners and split air conditioners. Therefore, it is one choice or the other. They both work in a similar manner, using refrigerant expansion to quickly cool the coil, which subsequently cools down the air that is passing over the same coil.

    The Set Up

    There is a difference, though, between the packaged and split systems. The difference is based on the precise set up of each. Similar to a vehicle, if the engine has to be placed in the front, then it is labeled a front engine vehicle. If the engine has to be placed in the back, then it is labeled as a rear engine vehicle. Even though, they are both vehicles and works in a similar manner by having a combustible engine, they have different labels based on the way that they are structurally set up. The same is true for the packaged and split air conditioner. Let’s take a closer look.

    The Parts

    The split air conditioning unit is made up of two detached units, the evaporative coil and the condensing unit. That is how the split air conditioner unit received its name. The split unit is joined by a series of copper tubing, which transports the refrigerant from the evaporative coil to the condensing unit.  If you notice two parts on your air conditioner, then your A/C is a split system. The condensing unit is usually found on the outside while the evaporative coil is inside. On the other hand, if your air conditioning unit has one part on the roof with ductwork installed into the roof, then it is obvious that your A/C is a packaged system.

    The Size

    Both the packaged and split air conditioner system has different sizes. The split air unit is about three times in size to that of the packaged unit, considering all their combined parts. The split air unit is cheaper and easier to fix and also to maintain. They are usually much quieter when in operation than the least quiet packaged unit.

    Conclusion

    To decide which type of air conditioner system you should consider, it is best to speak to an HVAC contractor. If you want to replace your current A/C system, it is also recommended that you seek professional guidance.

  • HVAC System Design for Commercial Installation

    HVAC Systems HVAC Systems

    Did you know that your heating and ventilation and air conditioning system provides your home with about 30% energy? This is common for small offices and residential homes as well. When you have a well-designed air conditioning system, it does adequately cool a building, but it also reduces the energy consumption. In addition, it also improves the building’s air quality without causing any damages to the environment.

    Industrial and Manufacturing

    In a manufacturing warehouse or industrial building, the HVAC system has various combinations of devices for heating and cooling. Some of these devices include:

    • Electric heat
    • Heat pump
    • Rooftop unit
    • Furnace
    • Chillers
    • Boilers
    • Central AC units

    For the commercial HVAC system installation, there are various system designs to choose from. For this reason, the installation should be done by an HVAC technician with industrial installation experience because some of these designs can be complicated while others are simple.

    Industrial Plant

    In the industrial plant, a basic system would be utilized in a single zone. Modifications are made when necessary to offer coverage to multiple plants or other large areas. For the basic industrial system, the air comes in from the air intake feature, which is usually found on the side or top of the building. Through atmospheric pressure, the forced air goes through a damper. The air is regulated to take in the amount that is required to cool the building. The air that previously went through the HVAC system will subsequently join with the external air.

    The Combination

    This combination is then filtered through the air filter, removing any large particles in it such as bugs, leaves and dust. After this, there is a second filtration process that handles the smaller particles prior to going through the fan. Once the air comes through the fan, it is then cooled or heated by the coils. If there is any condensation, a drain pan does the collection from the coils. The air then goes through the air duct to heat or cool the building, after which it returns through the air registers to be combined with newly created air or it goes out the building.

    Conclusion

    A basic HVAC system offers comfort to a specifically small space while a commercial HVAC system covers a wider space and has elements that consist of:

    • Packaged units
    • Window units
    • Heat pumps

    You will find a commercial system with evaporative coolers, chilled water systems and direct expansion coolers. So, if you own an industrial plant and need to have your HVAC installation done, the complex nature of it will require an experience and specialized HVAC technician. With a bad HVAC installation, you can end up paying higher cost in energy and have terrible air quality.

  • Issue that Regular Air Conditioning Maintenance Can Solve

    A/C Maintenance A/C Maintenance

    As with any equipment or appliance in the home, the air conditioner is a system that will ultimately need to be repaired due to wear and tear from being used regularly and possibly due to its age. When an air conditioning unit starts to lose its efficiency and capacity, most owners will be at a loss of what to do; whether to spend money on A/C repair or purchase a new air conditioning unit.

    Efficiency and Comfort

    Air conditioning maintenance is important throughout the life of your unit if you want to enjoy optimum efficiency, savings and comfort. In the meantime, it is best to take several preventative steps to avoid certain air conditioning problems, reducing recurring issues and allowing you and your family to enjoy the proper functioning of your A/C unit.

    Finding a Solution

    Air conditioning maintenance is essential to identifying problems and finding the right solution. First, though, you have to be aware of the common problems that could arise with your air conditioning unit. That way, you will know when to call an HVAC technician to assist you.

    Common Problems

    If your AC unit is not cooling as it should be, there is obviously a problem that you have to possibly repair. There are several things that could cause the AC unit from cooling:

    • It could be that debris or dirt has restricted the flow of air, resulting in blockage and therefore, a decline in the cooling capacity. The best solution for this is to do a periodic check of your AC filters, cleaning them or replacing them as frequent as every three months or according to the recommendations from the manufacturer. You could also schedule air conditioning maintenance with an experienced, professional and reputable HVA contractor.
    • Another possible cause for your AC not cooling properly is clogging of the heat exchanger. This subsequently results in the reduction of efficiency. The HVAC contractor, if called, would clean your radiator, but would first plug out the AC for safety.
    • In addition, your AC unit needs the right amount of refrigerant gas to operate properly. If not, then the excess heat in the room cannot be removed. The HVAC technician will identify if there is any leakage of refrigerant gas and may suggest that you schedule air conditioning maintenance to keep this from happening again.

    Other problems to look out for are the inconsistency of your run cycles, which could result from debris or dirt in your air conditioning unit. The dirt will cause the temperature sensor to rapidly cool and result in longer or shorter run cycle. The evaporator coils could also be affected.

    Conclusion

    An HVAC technician will check for corrosion in the plugs, terminals or wires of your air conditioning unit, inspecting also for electrical issues in the connections. If you believe that there is a problem with your AC, contact a professional AC technician for air conditioning maintenance.

  • Myths about Air Conditioning and Heating

    Air Conditioning Unit Air Conditioning Unit

    Air conditioning and heating are essential to a person’s comfort. It is also important to energy efficiency. Therefore, if you have a heating and air conditioning system, it is best that they cover these two things. If you really want to know the facts about HVAC, then you also have to become aware of some of the common myths that people have spread as it relates to your A/C and heating system. Let’s explore some of these myths.

    Temperature Adjustment

    Some people will say that temperature adjustment to your A/C unit and heating system is not necessary when you leave your house. However, this is not true. Paying attention to the temperature is important if you want to save on your utility bill. To save on energy during the winter months, it is best to lower the temperature and during the summer months, the opposite is true. You could invest in a thermostat that you can set to automatically adjust on schedule.

    Regular Maintenance

    Some homeowners don’t place a lot of emphasis on regular maintenance of their HVAC system. However, this is necessary if you want your units to last you for a longer period of time and operate efficiently. Don’t wait until your HVAC system breaks down to call a contractor. If your system is properly and regularly maintained, it could save you the headache.

    Higher Temperatures

    Don’t believe the myth that if you turn up the heater temperature, the entire house will heat up faster. The same thing is true for your air conditioning unit. The temperature will reach to the desired threshold in the same time period, no matter what you set it at. So, don’t waste your energy by setting it at high temperatures.

    Standing Fans

    Some people believe that using both the standing fan and air conditioner unit will lower the energy used. That is not true. Fans only circulate air and not keep the area cool. Therefore, the energy expended to circulate air carries no weight, if you are looking to cool your home. Moreover, you would be using unnecessary energy to operate the fans.

    Flexibility

    An A/C is not only beneficial if you want to keep an area of your home cool. No, an air conditioning unit does much more. In fact, it helps to lower the humidity in the air, making cooling more effective.

    Using Space Heaters

    There are people who genuinely think that the use of space heaters in a few rooms is less costly than operating a gas heater. A space heater only heats up a small portion of the space in comparison to your gas heating system. The best option is to have one heating system in a home instead of several space heaters.

    Conclusion

    If you have any issues with your air conditioning system or heating system, it is best to get the facts from a reputable and experienced HVAC contractor and not listen to what others say. Before making any decisions as it relates to your A/C and heater, it is best to speak to a professional.

  • Need to Know: Air Conditioning Freon and Refrigerant Leaks

    Freon Leak

    There are many tools that help air conditioning units function properly. One of those tools is a substance called Freon. It was created as a replacement for the dangerous coolant that use to accompany old cooling systems, such as refrigerators, freezers and air conditioners.

    Freon is a nonflammable, odorless and colorless liquid that has to be produced since it doesn’t occur naturally. It’s composed up of various amounts of chlorine and a host of many other different atoms that include fluorine, carbon and hydrogen.

    It’s a chemical that proves to be dangerous because of the potential impacts it ultimately causes to the environment, mostly with being a major factor in depleting the ozone levels. Such impacts have landed it to be banned in the U.S. with it only being manufactured through regulated material use. Before any item is disposed of, the Freon must be removed.

    More importantly, the process of handling Freon should only be attempted by licensed technicians who’ve been certified by the EPA. As far as the effects on humans are concerned, Freon isn’t dangerous unless it’s inhaled directly. Generally, a typical Freon leak isn’t enough to be harmful, but the presence can cause irregular heartbeats. This makes people with heart problems more susceptible to the fumes if they’re inhaled.

    Some of the common causes of Freon leakage include:
    • Physical damage
    • Condenser unit vibration
    • Stress points

    An outdoor unit that’s placed improperly outside can create strong vibrations that can weaken or fracture the lines that contain refrigerant. Physical damage that can cause leaks can be from other objects such as lawnmowers, which can cast rocks and sticks that can certainly cause damage to outside units. Stress points can also lead to Freon leaks which will be located near the units service valves.

    Identifying a leak can be quite easy if a homeowner knows what to look for such as:
    • The AC unit running at a specific temperature but not blowing any cool air.
    • The home is taking too long to cool.
    • Accumulated water near the furnace due to condensation.
    • The build-up of ice on copper lines from the AC unit to its outside coil.
    • An extremely high electric bill is also a very big indicator of a Freon leak. An AC unit with a Freon leak means that the unit has to work much harder to keep things cool, thus raising your electric bill. A Freon leak with only 10% leakage can raise the electric bill usage by double that amount.

    Small problems with Freon leaks can be attended to and fixed quite quickly once they’re identified and certified technicians are alerted not too long after they’re discovered. If problems aren’t handled and conditions are allowed to worsen, the repairs will take more time and money to take care of.

  • 3 Major Systems of the Home That Take Up the Most Energy

    Home Energy

    If you’re a homeowner or live in any type of housing complex, you know the feeling of receiving your utility bills each month and feeling your stomach drop at the numbers. Whether you want to lower your home expenses, be more environmentally conscious, or both, having knowledge of which systems of your home are consuming the most energy and how to reduce their consumption will be instrumental.

    Heating
    It’s tempting to turn the heating as far up as it can go when winter rolls around each year. However, this convenient household system is responsible for the largest percentage of the energy consumed by most houses. This is especially true for those who live in colder regions or who have particularly cold winters. Fortunately, it is easy to reduce the amount of energy used by your heater: Simply reduce the heat setting on your thermostat. Doing this might warrant donning a few more layers inside the home, but it is much easier to put on more layers or even use alternative sources of heat like a fireplace than it is to remove layers of clothing when the temperature gets swelteringly hot. Speaking of which, this brings us to a perfect segue into the next household appliance that is vacuuming the money from your wallet.

    Air Conditioning
    Unfortunately, one of the things we rely on the most to keep us cool during the warm months is also adding more and more digits to our electricity bills and consuming masses of energy. With 87 percent of U.S. households equipped with air conditioning systems as reported in 2009, it is easy to see why such a large portion of energy is spent on this luxury. The solution to minimizing this consumption, however, follows the same principle as the heating system: Adjust the thermostat. Opt for methods of cooling that don't utilize electricity in any way, such as ice buckets, cold drinks, and staying closing the shutters to keep sunlight from warming up your home. Ideally, utilize a combination of both natural methods and a low setting on your air conditioning to reach a comfortable temperature without your electricity bills going through the roof.

    Water Heater
    There's nothing better than the feeling of taking a hot shower after a long day. But sadly, yes, your water heater is responsible for a big portion of your home's energy consumption. In fact, it takes up about 18 percent of your utility bill on average. To combat this, you can do things as simple as taking shorter showers and turning the temperature of your water down a little bit. But if you want to implement a longer-lasting solution consider installing an on-demand water heater. This way, you can control when your water heater is on or off, thus saving you money and conserving energy.
