Air Conditioning Maintenance

Posted by on Nov 20, 2015 in Blog

Your air conditioner requires regular maintenance for it to stay efficient and effective throughout it’s life. If you fail to have it maintenanced regularly, you’ll find that your unit will continue to develop problems until the unit eventually requires replacement. The main parts of your air conditioning unit that need to be maintenanced are the filters, coils, and fins. Arguably, the most important maintenance task that will ensure the efficiency of your AC unit is to routinely replace or clean the filters. Clogged and dirty filters block airflow and significantly reduce a system’s efficiency. With normal airflow obstructed, air that passes through the filter may carry dirt directly into the evaporator coil and impair the coil’s heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner’s energy consumption by up to 15%. For central air conditioners, filters are generally located somewhere along the return duct’s length. Common filter locations are in walls, ceilings, furnaces, or in the air conditioner itself. Room air conditioners have a filter mounted in the grill that faces into the room. Some types of filters are reusable; others must be replaced. They are available in a variety of types and efficiencies. Clean or replace your air conditioning system’s filters every month or two during the cooling season. Filters may need more frequent attention if the air conditioner is in constant use, is subjected to dusty conditions, or you have fur-bearing pets in the house. Your air conditioner’s evaporator and condenser coil collect dirt over the life of their service. A clean filter helps to prevent the evaporator coil from being easily dirtied. But as time passes, the evaporator coil will inevitably collect dirt. Dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check your evaporator coil every year and clean it as necessary. Outdoor condenser coils can also become very dirty if the environment is dusty or if there is foliage nearby. You can easily see the condenser coil and notice if dirt is collecting on its fins. The aluminum fins on evaporator and condenser coils are easily bent and can block airflow through the coil. Air conditioning wholesalers sell a tool called a “fin comb” that will comb these fins back into nearly original condition. You should also pass a stiff wire through the unit’s drain channels occasionally. Clogged drain channels prevent a unit from reducing humidity. Excess moisture can discolor walls or carpet. At the beginning of the cooling season, inspect the seal between the AC unit and the window frame to ensure it makes contact with the unit’s metal case. If this seal is damaged, cool air will escape from your house. In the winter, either cover your room air conditioner or remove and store it. Covering the outdoor unit of a central air conditioner will protect the...

Different HVAC Filters

Posted by on Nov 13, 2015 in Blog

The air filters in your HVAC system are the first and most effective measure in protecting your heating and cooling system. Any HVAC professional will tell you to change your filters often. Using fresh filters will greatly extend its life expectancy and this preventative maintenance can save you money on repairs or down the road. Not to forget to mention, they help keep up the air quality in your home. Although some products claim to be effective for ninety days or even longer, most experts recommend changing your filters every thirty days. Regardless, you should inspect your filters regularly. The age of your HVAC system and the level of usage will determine how much wear and tear a filter suffers. You’ll know your filters need to be replaced when it’s coated in thick dust. When a filter is clogged up, not only is it no longer doing its job, it is decreasing the efficiency of your heating system as the dust starts to absorb heat. It also becomes a fire hazard. What filter is best for your home? There are a variety of filters to choose from depending on your budget and desired air quality. Fiberglass Filters: these are your standard filters for a homeowner on a budget. They’re composed of several layers of fiberglass mesh. These filter particles by physically trapping them in a dense net. While fiberglass filters are better than nothing, they tend to clog quickly and allow a large percentage of smaller particulates pass through. Electrostatic Filters: these filters are made from a material that generates an electrostatic charge as air flows through them. This static acts like a magnet for dust particles, attracting them and locking them into the filter. These are generally considered more effective than fiberglass filters, especially for residents with asthma, allergies or other respiratory problems. They should still be replaced at least monthly to get their full benefit. Electronic Filters: these filters operate by either drawing particles in with an artificially generated electrostatic charge, or by passing air through an ionizing device to charge the air around it and create an attraction between airborne particles and the filter. In either case, these filters are plugged into a power source and can be cleaned instead of replaced. These are generally considered the top of the line in filtration systems, and come with a increase in price. Specialty Filters: there are a number of companies offering specialized filters to combat specific air quality issues. Some come pretreated with disinfectants so they not only capture particulate matter but also kill airborne bacteria or viruses that pass through, making them a good choice for the immune-suppressed, or households with children or elderly residents. Filters containing activated charcoal or carbon are available that can reduce foul odors if a household has that problem. HEPA and micro-particle filters are generally considered the best for improving air...
