SEER Ratings and What They Mean
SEER rating are the method used to describe the efficiency of a particular equipment system. SEER stands for “Seasonal Energy Efficiency Ratio”. The systems purchased today typically range from 10.00 SEER to 18.00 SEER. If you have a home and the current system is 10-15 years old, you may have a system that ranges from 6.0 SEER to 10.00 SEER. Of course at the time it was installed, 10.00 SEER was considered “High Efficiency”. Today, with all the focus on conservation and energy savings, that “High Efficiency 10.00 SEER” from 10-15 years ago is growing obsolete.
WHAT ABOUT FREON??
Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon (HCFC). This colorless gas is better known as HCFC-22, or R-22. It is commonly used as a propellant and refrigerant. These applications are being phased out in developed countries due to the compound’s ozone depletion potential (ODP) and high global warming potential (GWP), although global use of R-22 continues to increase because of high demand in developing countries. R-22 use is increasing in developing countries, largely for air conditioning applications. Air conditioning sales are growing 20% annually in India and China. In 2012 the EPA reduced the amount of R-22 by 45%, causing the price to rise by more than 300%. For 2013, the EPA has reduced the amount of R-22 by 29%
R-410A, sold under the trademarked names Forane 410A, Puron, EcoFluor R410, Genetron R410A, and AZ-20, is a zeotropic , but near- azeotropic mixture of difluoromethane (CH2F2, called R-32) and pentafluoroethane(CHF2CF3, called R-125), which is used as a refrigerant in air conditioning applications. Unlike alkyl halide refrigerants that contain bromine or chlorine, R-410A (which contains only fluorine) does not contribute to ozone depletion, and is therefore becoming more widely used, as ozone-depleting refrigerants like R-22 are phased out. However, it has a high global warming potential (2088 times the effect of carbon dioxide), similar to that of R-22. Since R-410A allows for higher system efficiencies than an R-22 system, by reducing power consumption, the overall impact on global warming of R-410A systems will be substantially lower than that of R-22 systems due to reduced greenhouse gas emissions from power plants.R-410A operates at higher pressures than other refrigerants.
HOW DOES PLUMBING WORK????
Plumbing follows the basic laws of nature — gravity, pressure, water seeking its own level. Knowing this, you can understand the “mysteries” to your own home’s plumbing system.
The plumbing system in your home is composed of two separate subsystems. One subsystem brings freshwater in, and the other takes wastewater out. The water that comes into your home is under pressure. It enters your home under enough pressure to allow it to travel upstairs, around corners, or wherever else it’s needed. As water comes into your home, it passes through a meter that registers the amount you use. The main water shutoff, or stop, valve is typically located close to the meter. In a plumbing emergency, it’s vital that you quickly close the main shutoff valve. Otherwise, when a pipe bursts, it can flood your house in no time. If the emergency is confined to a sink, tub, or toilet, however, you may not want to turn off your entire water supply. Therefore, most fixtures should have individual stop valves.
IS YOUR KITCHEN SINK NOT DRAINING, BUT NOT CLOGGED?
“My kitchen sink has not been draining properly for months. When running the tap, the sink will fill up and drain very slowly. We’ve put commercial drain cleaners down it (including an enzyme based one, which we were told is what you use if there is no actual blockage?), but they’ve done no good. Also tried a bucketload of caustic soda, which hasn’t solved the problem either. We were told that it could be a venting problem.”
A vent stack is the pipe (usually inside a wall) that goes right up through the roof. it allows vapors to escape the house. It also allows pressure equalization. That is to say, if you didn’t have this stack the drains will not work very well.
If it is the vent stack, and it is plugged, when you get it open it will allow air to equalize in the sink drain. This is very similar to your ears popping when you go up in a plane. The pressure outside your ears is lower than inside your ears so the ear drum “pops” from pressure. If you swallow hard you “equalize” the pressure. Well this is similar to the vent stack’s function. If the stack allows air out (and in at times) it then vents the sink so that when the sink drains it doesn’t need to “burp” or “build pressure to a head”.
KEEP YOUR COOL!
Don’t wait for a crisis or emergency situation to occur. As the summer temperature’s rise and your cooling needs increase, remember to practice some preventative maintenance. We, at Ace Hi Plumbing, Heating and Air, recommend regular seasonal A/C inspections. We are presently offering a special rate for our general residential inspection.
