  • When do I upgrade my HVAC system?

    Air conditioner Unit Repair Air conditioner Unit Repair

    One of the most common questions asked about HVAC systems is, if my old system is running poorly, can I repair it cheaply? Or do I need to purchase a new system? Like most things in life, the answer isn’t simple: it depends on the age of the system, how well it has been maintained, and your current usage of it. In this article, I will go over a few of the things that you need to look at when deciding how to make your system more functional.
    First, consider the age of your system. It is important to examine not just how long you have used it, but how old the model is. Older models will usually be much less efficient, and can end up costing you more in the long run. So even if it seems to be somewhat fixable, if it is a very old system, it might be worth it to simply buy a newer model. You will save on energy, and have what is usually a quieter, more reliable system. A well-maintained HVAC system can last for 15 years or so, but generally if it is more than ten years old, it is time to think about a replacement.
    Second, look at the cost of a repair. Unfortunately, the cost to repair a system can sometimes cost near the price of a new unit. If you are facing a very expensive repair, then it might be a lot better to simply buy a new unit. This will be especially true if the unit is in poor condition, and will likely need more repairs in the future. Thankfully, lower end units can be purchased somewhat inexpensively if money is a major issue.
    Another important factor to keep in mind, is the energy efficiency of your old machine. Many older HVAC units have chemicals that are bad for the environment, in addition to being energy hogs. Check the SEER rating of your unit. A poor rating could definitely indicate that your unit is taking a lot more energy than would be needed by a newer unit.
    So, when weighing the cost of a repair with the cost of a new unit, make sure to keep these guidelines in mind. Often investing the money for a new system will save you money in the long run, and if you keep it well maintained, it will last you for a long time.

  • Why is my HVAC System Running so Poorly?

    HVAC 3The reason your HVAC system may not be working could be a number of things. Always make sure to take the necessary steps to keep your system running properly. Here are some common reasons and steps you can take to make sure your HVAC system runs properly always

    Uneven heating and cooling is a common problem with heating and air conditioning systems. Some rooms are nice and warm in the winter, others are chilly. Some rooms get comfortably cool in the summer, others are stuffy. Air flow has a lot to do with this problem. Dirty filters, closed vents, and ductwork issues can impede air flow, causing uneven heating and cooling. Home insulation is also a factor. Make sure to check or replace filters and make sure all the vents are clean and open.
    If you see enough dirt and debris on the air filter to fill a moon crater, you need to replace it. Or clean it if it is the washable kind. Filters should be replaced about once a month, depending on the system you have. If you don’t you’re making your system work harder than necessary. Also, check the heat exchanger and coils for any dirt.

    If there is water coming from the indoor unit of your HVAC system, you need to correct it as soon as possible to avoid water damage to your home. Water around the indoor unit means your system is leaking, not draining properly, or making excess condensation. Condensation can form on the evaporator coil and suction line if they are not properly insulated. If the necessary insulation is missing or leaving part of the coil or line exposed, more condensation collects on it, which can drip onto the floor. In some situations the coil may ice up, and when the ice melts it will leave a puddle on the floor. If the condensation drain is blocked it can cause pooled water. In the worst case, your system could be leaking refrigerant. Both air conditioners and furnaces can leak water.

    Another way you can track your HVAC systems issues it with your utility bill. Utility rates adjust often. If rates have remained steady while your bill has increased, you may have an issue that needs to be addressed. For AC systems, the federal government increased minimum efficiency ratings in 2006. If your system is older than that, it may be another reason for your higher energy bills.

    There are other things that can cause your HVAC system to run poorly. These are some of the most common and taking he steps provided will help you along the way.

  • Considering a Propane Conversion Kit for a Gas Furnace


    If you are looking for a gas furnace for your home or business, you’re probably looking at systems that are meant for use with natural gas (NAT). Most of the products on the market today are primarily intended for use with natural gas. However, with some systems -- including standard gas furnaces and combination heat and air conditioning systems -- it is possible to purchase  a propane conversion kit that makes it possible for your system to run on propane (LP) gas. As you make the decision, here are few things you need to take into account:


    Justifications for Fuel Conversion


    The primary reason why some home and business owners are interested in fuel conversion is that it allows them to diversify their energy dependence. Instead of just relying on natural gas, home and business owners who choose a propane conversion kit have the opportunity to utilize propane if the need arises. This can be especially helpful in emergency situations or other circumstances when natural gas is unavailable. With a propane conversion kit, you can take advantage of an alternative fuel source to keep your system going.


    Costs of an Add-On Propane Conversion Kit


    Adding a propane conversion kit when you buy a new furnace does come at a cost -- the current rate is about 99 dollars. However, this cost is significantly lower than the cost of buying a standalone propane conversion kit if you change your mind and want to buy one later. If you add one to an order before when you buy a new furnace, the cost can be 50 percent lower than the going market rate. Therefore, if you are on the fence about adding a propane conversion kit to your order, it might make sense to invest now instead of regretting it later.


    Ease of Setup


    Some propane conversion kits are notoriously hard to set up. Therefore, if you are choosing a furnace that is specifically designed to convert to LP gas, you should make sure that any propane conversion kit you buy will not become more of a headache than it is worth.


    It is important to note that not all furnaces are designed for conversion to LP gas. If you have the option of buying a propane conversion kit alongside your furnace, you know that it is. If not, it is important to take a close look at the product specifications before making any assumptions.
    National Air Warehouse offers multiple gas furnaces systems that can be converted to LP gas using a propane conversion kit, and we offer kits alongside our new products. Contact us today for more information!

  • Misconceptions About Your HVAC System

    People are often uneducated about their HVAC system. Many do not have the knowledge of the proper upkeep or things you need to do to maintain your system. Everyone wants to save energy and spend as little as possible and heating and air conditioning and having some know how may be all you need to do so. Here are some common myths and misconceptions about your HVAC system.


    You may hear the not using your system will keep it working longer or improve the HVAC system’s lifespan. This is actually incorrect. If you do not use your system dust and dirt may begin to collect. This can cause problems in your system so regular use is actually recommended.


    Turning on a fan is a great way to lower your energy bills if you find that you’re turning on the AC too often, but fans don’t cool down rooms in the same way that air conditioners do. AC units work by cooling down the air in the room, but fans produce cooling effects because the increased air circulation allows the sweat on your skin to evaporate faster, thus cooling down your body faster and making the room a little more comfortable. If you aren’t in the room when a fan is turned on, it’s really just a waste of energy.


    Humidity will not be effected if you raise the temperature. It cannot be controlled using the HVAC however lowering the temperature may lower the humidity.


    One of the most common myths about air conditioning is that you should raise the temperature on your thermostat way up when you leave for work or vacation. HVAC systems are designed to maintain constant temperature. The amount of energy used by your HVAC system to recover the temperature is more than if it remains constant. When leaving for vacation, raise the thermostat about 5 degrees, but any more than that can actually increase your energy consumption and costs.


    If the thermostat is located in near a vent or in direct sunlight it may not properly regulate your air conditioning system. This could cause your unit to start and stop frequently, which will lead to premature wear and tear.


    Now that you know a little bit more about your system you can take the proper steps necessary to keeping your home at the proper temperature. Proper temperature control will you keep you and your family happy all while saving you money.

  • Benefits of Switching to a Programable Thermostat

    As many sitcoms have pointed out, Dad is always in charge of the thermostat. No one touches it without Dad’s consent. Dad always has to turn it up and down and keep at the temperature he likes. In this day and age with modern technology we do not have to rely on Dad to control the thermostat. Programmable thermostats offer a new comfort and benefit to your home. Many people are making the switch to a programmable thermostat as it is easy to install and gives you control over your heating, ventilation and air conditioning unit.

  • When to Call in the Calvary: Should You Install Your Own HVAC or Phone the Experts?


    Installing an HVAC system on your own or with a partner may seem like the most optimal decision for you, however there are some things you must consider before attempting this task on your own. Not meeting certain requirements in the process can have legal and safety complications.


    Heating and cooling hardware require certain codes and regulations to be satisfied when they are installed. The professionals know these codes and will do their best not to violate any of them. If you decide to do this yourself please make sure you adhere to any and all heating and cooling regulations. Failure to do so can result in improper use of the system which can cause legal ramifications especially for businesses using these systems. Small business owners should absolutely consider getting a professional to install for them to avoid business being shut down for code violations.


    Installing a unit yourself may be more trouble than it is worth. You will need to track down a unit you want and at a price you are satisfied with. Professional installers can order directly from manufacturers usually for a break on the price you may not get. On top of the cost of buying the equipment you also have financial loss from the time it takes to complete. If you have a rigorous work schedule you will need to take time off as projects like this can last days for an inexperienced installer. This time off work also costs money and the cost may not outweigh the price of hiring a professional to do the work for you. Your hard work and time can be spent on another home project while the pros handle your heating and cooling.

    Technical Issues

    The installation process for a HVAC system is very technical. Experts go through rigorous training to make sure no mistake is made. They often go to school to learn the trade so that they do the job safely, efficiently and without invoking legal ramifications. Improper installation can lead to leaks in your system that could end up threatening your safety, not to mention the cost of paying for air you are not even getting!      


    After reviewing this information it is likely that hiring a professional installer is your best bet. It is not worth the safety and legal ramifications that you could unintentionally pull down upon yourself. Bigger mistakes may even end up costing you more than you saved from doing it yourself.

  • Lower your Heating Bill with some Improvements

    Winter is coming!! Fall is already here. If you are noticing that your house doesn't hold the heat in very well, here are a few tips for you.

    Inspect and Replace your Weatherstripping

    "What's that?" you say? Well, it's the seal on all of your outside doors that prevents cold air from seeping through the cracks around your door. Over time, this stuff gets worn out, and leaks air into your home. This will cool down your house in a hurry and make your heater work overtime.

    Check and adjust your Threshold

    This is the same principle. If you can see daylight under your door, that means there is cold air coming in and hot air going out. You may need to buy a new threshold, but usually the one you have can be adjusted with the screws that old it to the floor. Simply turn them to raise the threshold slightly and close the gap.

    Find the Holes in your Exterior Walls

    Why are there holes in your walls? Well, every pipe or electrical wire that goes into your home needs a hole, and it's entirely possible that one or more of those is not insulated correctly. You can plug these gaps with expanding foam to prevent the flow of air. As a bonus, this will prevent insects and mice from getting into your walls!

    Seal your Flue

    If you have a fireplace, your chimney is very likely to be leaking heat. Even with the flue closed, it will be leaking air. To solve this problem you can get a chimney balloon, or get creative and rig something up. This is a major source of heat loss, so it will pay for itself.

    Check your Ductwork

    Homes with forced air heating can lose a significant amount of heat through leaky ductwork. Sometimes you will lose a quarter of the warm air being pushed through in useless places like the attic. Inspect it wherever you can, especially around joints, and seal it up with metallic duct tape.

    Check the Locks on your Windows

    The locks on your windows are designed to push the window into the weatherstripping and create an airtight seal. If you forgot to lock one of your windows, it will be leaking air, and costing you money.

    Upgrade your Windows

    Shy of actual leaks, the windows are the most poorly insulated part of your exterior, and will allow the most heat to escape. If you have single pane windows, you will be losing a tremendous amount of heat through them. Single pane windows conduct heat out of your house very effectively and essentially do not insulate your house at all. Double pane windows work to insulate not because there is more glass, which does not insulate effectively at all, but because there is a layer of air between the panes of glass that does not effectively conduct heat out of your home, and thus prevents heat loss.

    Upgrade to a modern double pane and you will see a significant effect.
