There are a lot of components that make up the central air conditioning unit, and in order to troubleshoot what is wrong with your air conditioner, you need to understand a wide variety of components that make up the system including refrigeration, electricity, electrical components, electric mechanical controls and AC(air conditioning) components. Since the system can be complex it is probably better to have a trained HVAC specialist look at and diagnose the unit rather than attempt repairs yourself, but you should also be familiar enough with your ac unit so you understand how to maintain it.


How to Clean Your Furnace Filter in 3 Easy Steps

hvac ac unit The air conditioning filter is one of the most important air conditioning parts in the air conditioning system. Without it, your air conditioning system would be dirty and the air you breathe would be filled with pollutants. All air conditioning parts, from the ductwork to the air conditioning refrigerant, need the air conditioning filter to be clean and replaced to ensure you're getting the very best in central air conditioning.If an air conditioning filter is left dirty, over time, it can lead to higher energy costs and short equipment life due to all the air conditioning parts relying on each other. One can not work without the other. Overall, your heating and cooling will not be as effective and you will need to invest in more air conditioning repair and air conditioning maintenance.An air conditioning filter should be changed every month or every two months for home air conditioning systems and every couple of weeks for certain commercial or industrial air conditioning since it's running almost 24 hours a day, 7 days a week. Doing this as a routine in your monthly chores and not waiting until you see dust matted on the air conditioning filter will ensure you and your family the very best health as well as a smooth running air conditioning system . Dust particles can't always be seen so even if you see a little dust on the air filter, clean it as you normally would. Since there are a variety of air conditioning filters, how quickly one gets blocked versus another depends on the brand - most air conditioning filters are sized 1 ½ to 2 square feet for each ton of capacity for a home or commercial property.You can judge a filter's ability to clean by using MERV ratings - Minimum Efficiency Reporting Value - which is a rating of how efficient an air conditioning filter is from 1-12. The higher the rating, the more effective it is at removing particles such as animal dander, pollen, dust, mold and other allergens, and the better the protection for your air conditioning equipment. Most air conditioning filters screen out particles measuring from 3 to 10 microns in size.The common types of air conditioning filters are Conventional fiberglass disposable filters (1" and 2"): These are common in most homes and small industrial air conditioners and commercial air conditioning systems. Since they are disposable and have an adhesive coating that traps the dust, you should not clean the filters. This may damage the filter's ability to remove particles by damaging the adhesive coating and/or the underlying meshwork. They are both not as effective as other types of filters even though they are lower in cost.Pleated fiberglass disposable filters (1" and 2"): The 1" are generally used in many residential and commercial settings and are made of materials that can vary in the effectiveness. Usually, they are more densely woven to increase the efficiency of removing dirt. These have a larger surface area to lead to increased trapping of particles as compared to conventional filters. They must be specified for your air conditioning system or this can lead to increased demand on your air conditioning components. Thereby, a mismatch can be counterproductive to the health of the air conditioning system and possibly lead to higher air conditioning maintenance and service cost. You should check with the air conditioning manufacturer as to the appropriate type of pleated filter for your system. A filter spray can also be applied after the cleaning and drying of the air conditioning air filter. Electrostatic filters: Different in design and performance, since there are so many varieties, it is rather difficult to determine which is the most efficient. They are commonly advertised as allergy-free air conditioning filters. These filters also come in the 1" and 2" sizes. Air that moves through the filter creates a static charge that collects any dust in the filter. They may require more cleaning and more blower power. Electronic filters: Connected to an electrical power source and usually wall mounted, electronic filters come with a pre-filter that can collect larger particles and only need to be cleaned every six months.Carbon filters: These filters contain carbon that can control any odor problems you might have within the air conditioning system. They can also be useful in homes with pets. Air Conditioning Filter InstallationWhen placing the appropriate air conditioning filter into the system, the filter should be placed in the correct direction as indicated by the arrow located on the side or face of the filter. Air should flow in the proper direction which is in the same direction as the arrows. This allows the filter to work appropriately, as the air exits the filter in the most reinforced part of the filter.The air conditioning filter should fit tightly. A perfect seal is necessary to prevent unfiltered air from entering and damaging your air conditioning system. Without a perfect seal and appropriate sizing, the filter is useless. Additionally, the non-conventional filters may have a higher efficiency and may not fit your system. This should be checked with an air conditioning company, contractor, or air conditioning supply company.

hvac ac unit Air conditioners regulate the temperature indoors during hot days, keep out pollutants and contaminants, and maintain comfortable humidity levels in the home. Despite the amount of use AC units get, many homeowners wait until small issues become large problems to schedule an air conditioning repair service. Here are a few common reasons for repair calls. Lack of maintenance when it comes to keeping an HVAC unit in good working condition, regular maintenance is key. A routine tune-up can help keep units working all summer long. When homeowners neglect regular maintenance, small issues can become costly headaches. Remember, technicians can spot damage before it causes a major issue. Moisture Inside the System Air conditioning units is designed to reduce the risk of moisture building up in the system. A central drain line funnels excess moisture outside, where it can do no damage to the home. However, if the drain line gets clogged, water can pool inside the system, leading to corrosion, mold, and even electrical issues. Furthermore, the moisture build-up can attract pests that can damage other parts of the home. These repairs require an experienced professional and should not be handled by the homeowner. Overused and Overworked AC Units during the hottest days of the summer, many homeowners run their systems continuously. While this does keep homes cooler, it can also damage the air conditioning unit. The constant use places a lot of strain on the system and can cause severe damage when the unit is not properly maintained. An overused unit may even stop working, resulting in an expensive air conditioning repair that could likely have been avoided with a routine maintenance appointment. Improperly Sized AC UnitsWhen a technician installs a unit, they always look at the size of the home to determine which unit will work best. If a unit is too small to cool a home properly, the air conditioner may break, forcing the homeowner to call an air conditioning repair technician to assess the problem. It's important to note that unless the unit is upgraded or supported by additional units, an undersized AC will likely break again after repairs. Faulty WiringWhen an unlicensed contractor or handyman installs an AC unit, they may not be familiar with the proper safety protocols for installation and could wire the unit incorrectly. If this is the case, the air conditioner won't work as efficiently and may even be a fire hazard. Homeowners who notice that their unit runs without cooling the room or constantly trips the circuit breaker should schedule a consultation immediately. Avoid these common repair problems by scheduling routine maintenance each year. Call a local AC repair expert to be prepared for summer before it arrives.
