Cooling load Load calculation Measurements that calculate what size system is appropriate for a particular structure given its square footage, ductwork analysis, insulation, windows, etc. Condenser The outdoor unit that keeps the refrigerant cool. Heat Pump An air conditioner equipped with a valve that lets it switch between cooling mode and heating modeHVAC Heating, Ventilation, and Air Conditioning equipment. SEER A measure of efficiency for air conditioning units the higher the SEER number, the more energy efficient the unit is in cooling the air. SHR A measure of efficiency for the ability of air conditioning systems to remove moisture or humidity the higher the SHR number, the less capable the system is in removing humidity. Supply Return Supply registers and ducts bring conditioned air in return registers and ducts draw air out to be reconditioned. Ton A measurement of size used to determine cooling capacity. Ventilation The natural or mechanical process of supplying conditioned or unconditioned air to, or removing such air from, any space. Why should I be concerned about the efficiency of my air conditioning system The largest consumer of energy in the typical Florida home is the heating, ventilation and air conditioning HVAC system, which can account for more than 4. Energy use by your HVAC system is affected by many factors such as insulation levels, system efficiency, shading on the home, quality and sealing of the windows and doors, design and integrity of the duct system, and, of course, how the system is used. Because of the heat and humidity, most Florida residents today rely on air conditioning systems to maintain not only reasonable comfort levels, but lower humidity levels as well. The size, efficiency, and placement of an air conditioning system, therefore, are all important. Equally critical is the air conditioning contractor selected, particularly because the operating efficiency of a system relies on proper installation to achieve its performance rating. A skilled air conditioning contractors keys to obtaining the designed efficiency of a system in the field include proper sizing of the system for the specific cooling load of the home selection and proper installation of thermostats or controls proper installation and commissioning of the system and, if required, a duct system designed to deliver the correct amount of conditioned air to each space within the building and sealing and insulating all ductwork. Isnt bigger betterSizing the air conditioner close to the actual load cooling requirement provides better humidity control and typically results in energy savings when compared to an oversized air conditioner with the same performance characteristics. Better humidity control results from a higher percentage of run time during which the coil is operating at its coldest temperature allowing more condensate to form and flow out of the system, while energy savings result from less start and stop operation and higher comfort levels due to better humidity control. Reducing the number of cycles may also result in longer equipment life. However, close sizing also comes with requirements. Since there should not be large excess capacity on the hottest days, the system must be properly maintainedmost importantly, keep it clean. Also, energy efficient features of the house that reduce air conditioning load such as proper sealing of ductwork, windows, insulation and sealing against infiltration must actually be done and done correctly. To assure proper sizing, the load must be calculatednot just estimated based on square feet. Load calculations are based on the exact area, orientation, insulation levels, type of construction for each component of the building envelope, as well as the heat given off by the lights, people, and equipment inside the building, etc. The standard for residential air conditioning sizing is ACCA Manual J or a method based upon Manual J. ACCA stands for Air Conditioning Contractors of America. Make sure your contractor conducts comprehensive load calculations before accepting a bid. Central air conditioner and heat pump capacity is generally referred to in terms of tons. A ton of air conditioning is equal to 1. British Thermal Units BTUs per hour. What exactly is SEER The cooling efficiency of a heat pump or an air conditioning system is rated by the Seasonal Energy Efficiency Ratio SEER. The SEER is defined as a ratio of the average amount of cooling per unit of electricity used. The amended Federal Standard on residential air conditioners specifies that central air conditioners and central air conditioning heat pumps manufactured after January 1, 2. SEER for split system heat pumps. Efficiencies of some systems can be as high as SEER 2. It is important to understand that even though the SEER may be high, if the system is inefficient for example, leaky ductwork or oversized, you will not receive the full value of the efficiency as the air distribution system is not used to determine the SEER rating. So a high SEER system will also take care of the humidity in my house, right Not necessarily. You also need to consider the Sensible Heat Ratio SHR, which describes the moisture removal capability of air conditioning systems. A SHR on HVAC equipment of 0. It is critical that the HVAC contractor accurately estimate the humidity load also referred to as latent load. Outdoor air, coming in through poorly sealed windows and doors, open fireplace dampers, and bath and kitchen vents, causes most of the moisture load in your home. Even the simple act of opening and closing exterior doors adds humidity to your home. In addition, plants, bathing, cooking, cleaning, combustion, standing water in commodes and drains, and even breathing add to indoor humidity. A proper Manual J load calculation yields both the latent moisture load and the temperature based or sensible load. Typical dehumidification is performed by systems that use the same basic mechanics as air conditioners, and often air conditioners alone dehumidify the space. To keep humidity within comfort ranges, the buildings thermostats should have humidity sensors. If they do not, you can specify separate systems that can control humidity separately from the HVAC system. However, both comfort and energy efficiency will be better when humidity control is integrated with temperature control. Mechanical dehumidification is not the most energy effective means of dehumidifying, but it is the most common because it uses standard technologies. Mechanical dehumidifiers over cool incoming air below the dew point the point where it can no longer hold all the water vapor that was in solution. As a result, the water condenses on the cooling coils. Nova Heating Air Conditioning. How Often Should You Change Your Ruud Furnace Air FilterI only change my Ruud furnace filter when it looks dirty. Although this is a common assumption of how to know when to replace a furnace filter, it is not good advice. If you can see a build up of particulates on your filter then it should have most likely already been replaced. A dirty filter not only reduces the efficiency of your furnace but more importantly, negatively impacts the quality of the air you and your family breathe. But how do you know when to change your filter The correct answer is it depends. Many manufacturers recommend that you change your furnace filter every three months. But this is only meant as a guideline. As you might have guessed, every household is different. A variety of factors may determine how often you change your filter. They include the type of filter, specific conditions in the home, and furnace usage patterns, to name just a few. How Often Should I Change My Air Filter The required change out frequency varies with filter type, unit location, and other environmental factors. For residential applications, standard disposable polyester or pleated air filters should at least be checked every 3 months. Often after that length of time, a filter will require a change, however environmental factors such as pet hair, heavy foot traffic in your home, and tobacco smoke can decrease the life of your filter requiring a more frequent change. For higher efficiency filters or other types of media air cleaner, the life can range from 6 months to over 1 year. Commercial applications have an even broader spectrum of change out frequencies. Air filters in restaurants are commonly changed every 4 to 8 weeks depending on the customer traffic and filter type. Retail chains, strip malls, and other small businesses vary, but usually are in need of a change every 1. Industrial facilities, depending on the nature of their business, often require a filter change out every week. Plants with heavy smoke, soot, and other airborne contaminants require a massive filtration system, and with all the pollutants in the air, the filters can quickly become saturated.

Do Dirty Air Filters Really Increase My Utility CostsYes As your air filters get dirty, they begin to restrict the air flowing through the unit. This causes the HVAC unit to work harder to maintain a sufficient air flow. Because your unit is working harder and longer, it is using more electricity, which over time can dramatically increase your utility costs. In addition, dirt acts as an insulator disrupting the heat transfer of the air flowing through the unit. Call NOVA Heating and Air Conditioning to have your filters changed today This also causes your unit to work harder, which uses more electricity. There is an optimum time to change any air filter which is when it has reached its maximum efficiency with out becoming restrictive. By changing your filters on a regular schedule, you really can save money on your utility costs, and help promote a cleaner environment. Not regularly changing your air filters can also lead to costly mechanical breakdowns. Keeping your air filters clean is truly the most cost effective way to maintain your expensive HVAC equipment, and a cleaner environment for your family, friends, and co workers. System Checks If you have a forced air heating system, check your furnaces blower compartment and blower coils. Vacuum them if you see dirt and dust there. You should also check the fan belt tension, and lubricate the fan and motor bearings. If you have a steam system, check the shut off valve for leaks. Bleed hot water system radiators at least once a year. Dont keep clutter near your furnace. Its a fire hazard, and may keep your system from operating efficiently. To make sure youre getting the most out of your heating system, keep the heating registers and vents throughout the house free of dust, dirt, and pet hair by vacuuming them at least once a year. Listen for odd sounds when your heating or cooling system kicks in. If you hear anything unusual, get in touch with your service professional so you can head off problems before they become serious. In winter months, set your ceiling fan at its slowest speed and reverse it in order to gently push warm air down from the ceiling without generating a breeze. Caution first NOVA Heating and Air Conditioning says to show everyone in your family the location of the main shut off valve to your home as well as emergency shut off valves for separate fixtures, particularly toilets, kitchen sinks and bathroom basins. Dont see one Consider installing these valuable devices to minimize flooding. Keeping your HVAC system clean. Getting your HVAC system inspected twice a year by NOVA Heating and Air Conditioning is the ideal situation for most people. This will allow for two important things to occur 1 This will make sure your system is running effectively and efficiently and that no issues are apparent thus ensuring your system will work when needed. It will ensure your system is clean of debris and in this case, moldmildew formations and thus avoiding any of the potential health risks associated with moldmildew. Installing an air purification system into your HVAC system will greatly reduce, if not completely eliminate up mold, bacteria, odors, viruses, smoke and VOCs leaving behind clean, fresh and odor free air. Can mold cause health problems Yes Molds are usually not a problem indoors, unless mold spores land on a wet or damp spot and begin growing in the case above, its the evaporator coil. Molds produce allergens substances that can cause allergic reactions, irritants, and in some cases, potentially toxic substances mycotoxins. Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals. Allergic responses include hay fever type symptoms, such as sneezing, runny nose, red eyes, and skin rash dermatitis. Allergic reactions to mold are common and the reactions can be immediate or delayed. Molds can also cause asthma attacks in people allergic to mold. In addition, mold exposure can irritate the eyes, skin, nose, throat, and lungs of both mold allergic and non allergic people.
