  • How Natural Disasters can Adversely Affect your HVAC System

    HVAC system HVAC system

    Even though, you may be keenly concerned about your uprooted trees, windows, and roofing system, after you have experienced a natural disaster, your HVAC system could also be in jeopardy. Once the natural disaster passes and your electricity is restored, it is crucial that you become familiar with the ways that a storm or hurricane could damage or destroy your HVAC system.

    Lightning Effect

    When lightening does strike, it can adversely affect your air conditioning or cooling system since this relies on electricity in the home to function properly. When the electricity is disrupted, it could cause issues to your air conditioning system. The additional power resulting from a lightning strike could flood the circuit breaker in your home. It could damage electronics and appliances. It would be recommended that you install a surge protector prior to any natural disaster. This can absorb most of the electricity before it can damage anything in your home. A surge protector is also important in saving your HVAC equipment.

    Hail Effect

    When a tornado strikes, it comes with high winds, but also lightening. Hail, on the other hand, could follow a tornado or severe storm. It comes with heavy pelts that could subsequently damage your HVAC system. To protect the fragile parts of the condenser coil, it would be ideal to install a hail cover over the air conditioning unit. It may not deflect everything since small debris can go through the guard, lodging in the equipment. When this happens, you should contact an HVAC contractor for some assistance before even making an attempt at using your air conditioning again.

    Water Damage

    A storm or hurricane comes with lightening and heavy rains, causing water damage. In fact, when the storm hits an area, its slow movement could cause a significant amount of water to accumulate in your yard and around your HVAC system. Debris and grass could wash into the HVAC unit as water rises.

    Conclusion

    Before you experience severe weather, it would be an excellent idea to contact an HVAC contractor to inspect your outside HVAC unit. The HVAC professional would make sure that the unit is elevated to a height to keep out as much standing water as possible. You could also consider placing a mesh cover over the condensing unit. The mesh cover will be able to keep water from heavy rains from getting inside the unit. Always be mindful, though, that you should remove the mesh cover when you want to use your air conditioning unit. If you don’t, it will block the air flow.

  • Hysteresis Thermostat and What You Should Know

    Hysteresis Thermostat Hysteresis Thermostat

    Individuals get hung up over complicated terminologies like ‘hysteresis’ and more often than not, these terms can be simplified with an easy explanation that can be understood by anyone. In the same manner, hysteresis is considered an engineering terminology that is used to explain a simple ‘lag.’ It is specifically the way that a reaction lags a step or an action. Let’s take a closer look at this simple example below.

    An Example

    If you were to squeeze a piece of foam and then release it, you would hear a popping sound as if it popped back to its original form. However, it does not do so immediately. It goes back to its normal state in a slow motion. It lags this action until the release of your hands. Other forms of hysteresis are the same way.

    The Thermostat

    The common use of hysteresis is during the use of magnetic and electronic systems. Thermostats are a perfect example. Without using technical applications and definitions of hysteresis, let’s look at how it applies to thermostats. The hysteresis thermostat also goes through a similar motion; it lags inputs from the surroundings for the main purpose of saving energy as well as preventing a furnace or air conditioner from enduring wear and tear as it frequently turns on and off.

    Poor Insulation

    If you live in a house that is poorly insulated and the temperature outside is a scorching 104 degrees, your main concern is how long it will take for the heat to penetrate your house while the air conditioning unit is running. Believe it or not, this would not take long. With a good HVAC system, your house will cool to about 72 degrees, which is quite comfortable. When the insulation is insufficient, in about one minute, the temperature will increase to 73 degrees and your air conditioner will kick in again. This cycle continues to be repeated frequently as your air conditioning unit is overworking due to the poor insulation. It is, therefore, difficult to maintain the comfortable temperature in the home.

    Saving Energy

    You would not classify this thermostat as a hysteresis thermostat because of its lack of hysteresis in the programming. For that reason, it will constantly turn on and off. With a hysteresis thermostat, you can set your temperature to 72 degrees and be able to maintain it. Why? The temperature will go up to 74 degrees before cooling it to down to 71 degrees, allowing the HVAC system to relax. This saves on wear and tear and also fosters energy efficiency.

    Conclusion

    It is important to get your HVAC system working efficiently and therefore, you could consider using a hysteresis thermostat. It will definitely work in your best interest. Speak to a HVAC contractor to discuss your immediate needs.

  • What the HVAC Contractor Thinks About the Trane and Lennox Brands

    Lennox and Trane Lennox and Trane

    If you are going to purchase an air conditioner unit or heating system, you want to do a comparison brand. In this case, let’s take a look at the Trane and the Lennox brand. Comparing these two will give you a general idea on how to compare others.

    Lennox

    Lennox provides materials and equipment that may equally compare to the competition. However, their parts are difficult to find. The competition, Trane, provides a wide range of logistics supply chains and Lennox does not since its supply chain is proprietary and does not give as many choices to the consumer. What does this mean for the consumer? Well, if you were to order replacement parts from Lennox, you would have to wait sometimes for weeks for it to arrive. If you were in need of repair, it is best to hire a professional HVAC contractor. If you sent your air conditioning unit, for example, for a Lennox repair, you would have to wait much longer for their technician to get the parts. Not that the Lennox brand will break down often. It is that when they do break down, it is difficult to handle the repair aspect.

    Expensive Brand

    On the other hand, the Lennox brand tends to be more costly than the Trane brand. Many people think that the more expensive brand is superior to the other. However, this is not necessarily true in all cases. Both brands can break down does as its competitors and none of these two seems to offer any advanced technology that the competition does not have. The point is you are looking for the best value for the money you spend as a consumer. Many consumers tend to think that the customer service offered by Lennox is poor, even though, their equipment has a warranty. They are hard to deal with and don’t have many distribution centers to handle customer complaints efficiently.

    Trane Brand

    Trane, on the other hand, does not have the issues that Lennox does. However, many consumers found that warranty payouts were hard to get. Trane and aluminum coils go hand in hand. In the past, most air conditioners were made with copper and there weren’t as many repair problems. Aluminum coil is used by Trane and other brands to reduce the cost, but it does not necessarily help the consumer in the long run. Air conditioners with copper coils are easier to fix.

    Conclusion

    The bottom line is that the HVAC contractor that you use for your air conditioning or heating system installation is far more important in comparison to the equipment brand you choose. However, at the end of the day, despite the fact that Lennox brand has a good reputation, there are too many issues that can go wrong with its HVAC system. It is best to conduct an extensive research, but even better, it would be more ideal to hire a good HVAC contractor. You cannot afford to hold back on on this part of the equation. One more point to make is that you should take care of your equipment and try to have a contractor provide regular maintenance.

  • 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.

  • Factors to Consider in Making an Air Conditioning Brand Selection

    AC Brand AC Brand

    It is quite difficult for someone to feel comfortable during the summer months without having air conditioning in the home. It is also difficult when your air conditioning unit breaks down and you don’t know a good HVAC contractor to call for repair services. It is even more difficult when you have upgrade plans for the home and are getting ready to purchase a central AC unit, not having a clue on which brand to purchase.

    The Pros and Cons

    Each air conditioning brand comes with different pros and cons. Even for a specialist or expert in the industry, it is a tossup at times to suggest the ideal brand for a customer without first inspecting the home and discussing the client’s needs. There are several critical aspects to consider when choosing the right AC brand whether you are upgrading or making your first purchase.

    Longevity

    When you are trying to select the ideal air conditioning brand, lifespan and longevity should be your first concern. You want to buy an AC unit that can stand the test of time and still operate efficiently over a number of years. The earlier AC systems will tend to last longer, usually about twenty years. However, the advancement and development of more sophisticated systems and mass production may not hold true to the same longevity of the past. For example, you may find the thermostat on one AC brand works better than on another. Contact a HVAC contractor with the knowledge and experience to advise you on which of the AC brands will last longer and work more efficiently. It is good to also note that most air conditioners that are the most recent models will come with five year warranty on servicing of parts, labor and compressors.

    Energy Efficiency

    Even if durability is not one of the advantages of newer models of air conditioner units, energy efficiency tends to be an area of strength. This could be due to the interest that consumers now have in energy saving devices. Manufacturers have answered the call in making appliances with the energy star score in mind. Most of the leading AC brands have up to a seven star rating. This significantly reduces the amount of energy air conditioning units required for use. So, when you are looking to choose the best brand, pay attention to the energy star score. This will help you to save on your utility.

    The Features

    Look for the features on the brand that you are interested in. Some of these features will give you a better cooling performance. This could include:

    • Inverter
    • Compressor size
    • Timer control to preset the on and off times
    • Thermostat
    • Zoning – dividing the home into different zones
    • Advanced and sophisticated climate control to regulate the temperature in each room
    • WiFi and remote access to turn on the air conditioner several minutes before getting home

    Conclusion

    When selecting your AC brand, you should also consider the reputation of the company and if there will be any additional support offered after your purchase. Most of the well-known brands are Toshiba, Samsung, Mitsubishi and Carrier. However, consult with your HVAC contractor before you make the purchase.

  • 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.

  • HVAC Systems Last Longer with Regular Maintenance

    HVAC System

    Most homeowners want their HVAC system to last for as long as possible. Not surprisingly, regular maintenance on an HVAC system can help it to stay in good working condition. Take a look at just a few maintenance practices that can contribute to the long life of an HVAC system.

    Changing the Air Filter
    This is a simple maintenance practice that should be done about every 90 days. Over time dirt, dust and pet hair can clog an air filter in an HVAC system. This debris prevents an HVAC system from working at its most efficient. In addition, a clogged air filter isn't able to capture any more dirt and debris. This affects the overall air quality in a home. Maintaining good air quality in a home is especially important for occupants with respiratory conditions such as asthma.

    Clearing the Space around an Outdoor Unit
    Sometimes weeds, vines, brush and other vegetation can grow too close to an outdoor air conditioner. This type of growth can interfere with the efficient operation of the unit. For instance, weeds and vines can push themselves against the coils of the air conditioner causing damage. It's best if there is approximately two feet of space around an outdoor air conditioning unit.

    Cleaning the Evaporator Coils
    Often times, moisture accumulates on the evaporator coils of an HVAC system. This moisture creates an ideal environment for mold to grow. The presence of mold is unhealthy to the occupants of a household. In addition, this mold can damage the coils. The evaporator coils need to be examined and/or cleaned on a regular basis.

    Checking Electrical Connections
    Over time, the electrical connections within an HVAC system may become loose or damaged. A broken electrical connection can prevent an HVAC system from working properly. It's best to check these connections to fix the problem before costly repairs become necessary.

    The Benefits of Calling a Certified Technician
    Finally, there are many reasons to call a certified HVAC technician for regular maintenance services. For one, a certified technician is trained to recognize potential problems in an HVAC system. This can help a homeowner to avoid expensive repair bills in the future. Also, a certified technician knows how to provide maintenance services in a safe way. He or she has the skills and equipment to make sure a system is operating at its highest level of efficiency. In addition, a certified technician can keep track of a maintenance schedule. Consequently, a homeowner doesn't have to remember when it is time to check the air filter, evaporator coils, vents etc. The technician takes care of the maintenance work as well as the schedule!

  • What is a Pre-Charged Cooling System?

    Pre-Charged Cooling System

    A pre-charged cooling system is charged with refrigerant and doesn't require additional services for adding refrigerant. The cooling system is used to cool air that’s circulated throughout a home. The systems are usually installed by licensed professionals, such as HVAC technicians. The pre-charged units eliminate the need for removing the air from the system by creating a vacuum, brazing the metal parts together and then charging the system by adding refrigerant. The refrigerant is inside the units, which have no leaks. However, any connected parts could be a source for leaks and must also be sealed.

    Components
    Air conditioner units have three very important components. The AC condenser, evaporator and compressor must function in unison because the refrigerant repeatedly changes from liquid into a gas and from gas into a liquid. Warm air transfers heat to the coils and causes the liquid refrigerant to change into a gas. The compressor is used to pressurize the gas, which forces the gas to change into a liquid. A pre-charged unit is sealed to prevent leaks and usually connected to the system with quick connect fittings.

    Metal Tubing
    The cooling system has metal tubing that also holds the refrigerant, which moves through the system. The tubing is sealed and usually quite fragile. Therefore, the HVAC technicians must carefully handle the units and ensure that the refrigerant is not accidentally released through a crack in the tubing. There are quick connect fittings installed on the metal tubing, which are used to connect to the pre-charged unit that supplies refrigerant to the entire system. The metal tubing may also be connected by brazing, which is similar to soldering. However, brazing requires a much higher temperature because the filler metal has a higher melting point than solder.

    HVAC Technicians
    The HVAC technicians must have special licenses for handling refrigerant, which is consider to be a source of problems for the environment. There are refrigerant recovery machines that’re used to collect refrigerant from units. The refrigerant shouldn't be released into the environment and should ONLY be handled by licensed professionals. Therefore, leaks should also ONLY be repaired by technicians who are licensed to handle refrigerant.

    Benefits of the Pre-Charged Units
    The pre-charged units offer the additional feature that the components will probably not need to be checked for leaks, which is another service that is eliminated. Leaks are serious problems with cooling systems because the refrigerant can leak from the quick connect fittings, from a crack in the tubing or from a component, such as from a condenser. The HVAC technicians usually charge a system with refrigerant and then quickly search for the source of a leak. Therefore, the pre-charged units can save time during an installation and help to eliminate inspections for leaks.

  • How is a Split System Different from a Package Unit?

    Split System Different than a Packaging system

    Central air conditioners come in two form factors: split systems or packaged units. These systems have significant differences and there are pros and cons associated with each.

    Split Systems
    These systems consist of two main parts: a metal cabinet that sits on a concrete slab outdoors and another cabinet that is installed inside the building, hence the term "split." The indoor cabinet may be inside a closet, basement or in an attic and will often include a furnace. The indoor and outdoor parts of the split system are connected to each other via a refrigerant line.

    The outdoor cabinet houses the compressor and condenser, while the indoor cabinet houses the evaporator.

    Split systems have the potential to be far more efficient (as high as 25 SEER), though installation involves two units instead of one like with a packaged unit. Two units may be more difficult to install than one; it’s also important to note that unlike a packaged unit, a split system cannot be charged until it’s installed. Homeowners should also note that proper installation is crucial for optimal performance. If a split unit isn’t installed properly, this can severely reduce its lifespan.

    Packaged Units
    The air conditioner's main components like the evaporator and condenser are all in one cabinet, and are thus "packaged." Most of the time, the cabinet is located somewhere outside the building, usually on the roof. In some cases, a packaged unit will include electric heating coils or a natural gas furnace.

    Since packaged units are installed outdoors, installation is easier and they save on space in the building. Packaged systems may also work better once installed since they’re assembled in a controlled factory environment and come pre-charged with refrigerant; both factors can ensure optimal function once they are installed. However, their efficiency potential is much less than that of split systems (15 SEER at most). Another drawback comes from the fact that packaged units are placed in a harsh environment; the elements along with wild animals such as raccoons can cause problems. Animals can chew on wires or nest in the cabinet.

    Costs
    Price could be considered another factor. Packaged units are usually slightly more expensive than split systems but since the installation of split systems is more labor intensive, they both wind up costing roughly the same overall. A split system may be less expensive if the home is already equipped with a furnace and the property owner is replacing an older air conditioning unit.

    When choosing between the two, the determining factor may be the building in which the system is to be installed. While larger and newer buildings may have room for the indoor part of a split system, a packaged unit may be the only option in a smaller or older one.

  • Main Reasons it's Better to Buy from an AC Wholesaler than a Retailer

    AC Wholesaler

    The cost of a new residential or commercial air conditioning system may range from a couple of thousand dollars to considerably more. The total price that you pay may be related to the BTU rating of the unit, the energy efficiency and other related factors. When you’re interested in making an AC unit purchase, you may understandably be focused on finding the best value available. You may not realize it, but you can purchase an AC unit with wholesale pricing, and there are several benefits associated with this.

    A Greater Selection
    When you purchase an AC unit from a retailer, you may have a limited selection of products to choose from. This is because a retailer may only carry a few models from a couple of manufacturers. In some cases, you may find the ideal unit for your needs in this limited selection. However, more often than not, you may feel as though you’re settling for a unit that’s not quite right, simply because it’s the best option available. When you work with a wholesaler, you’ll have access to all of the models of AC units made by that manufacturer, and this means that you may be more likely to find the perfect system for your needs.

    No Middleman
    An air conditioning system wholesaler typically provides discounted rates on AC units to retailers, but you may be able to take advantage of these low rates as a consumer. Retailers will mark up the price of the AC units so that they make a profit when they sell the unit to you, but this mark-up is eliminated when you purchase the unit from a wholesaler. Essentially, this is a great way for you to better control the cost of your unit. You’ll enjoy a lower rate on the unit, and you can negotiate or shop around for the best rate on labor costs for the installation.

    The cost of a new air conditioner for a home or commercial building can be considerable, and you may be wondering where the best place is to make your purchase. At National Air Warehouse, we carry a wide selection of units, parts, and accessories to choose from at affordable prices.
