Maintenance For Your Home Hvac System.
The preventative maintenance on your residential air conditioner is crucial to saving dollars through the summer months. Not only does it cost much more to run an ineffecient air conditioning system, it puts stress on the system as well. Although hvac systems by their very nature are complicated for the average home owner, some of the most serious aspects of air conditioning preventative maintenance amounts to simple cleaning. The condenser coils: These are the coils at the condensing unit outside. Dirty condenser coils may be the biggest culprit in energy loss when it comes to air conditioning. It's the job of the condensing coils to offload the heat that is removed from the inside of the house and if the coils are clogged with grass, dog hair or dryer lint, then the pressure in the condenser skyrockets. Not only can the heat not be removed properly, this puts stress on the compressor. The easiest way to clean the coils is to disconnect the power from the unit, remove the screws that hold the fan, pull the fan up or out and then take a garden hose and spray the coils from the inside of the unit to the outside. Since the fan pulls through the coils from the outside to the inside, spraying from inside out does the most for removing junk from your coils. Dirty filters and evaporator coils: Filters are another home air conditioning problem that is servicable by most home owners. Dirty filters cause low airflow across the evaporator coils which can lead to low turnover in house air. If the air is too slow across the evaporator, it can freeze up which will virtually stop the cooling in the house as the evaporator coils turn into a block of ice. A missing filter over a period of time will lead to a clogged evaporator coil which will lead to perpetual low flow across the coils and a service tech is usually needed to clean inside coils. As you can see, low air flow across the coils inside or outside can result in high energy bill and a system that just doesn't cool well. On a number of service call I've went on over the years when the complaint was "it just runs all day and doesn't get cool", it turned out to be dirty filters and coils.
