Condensing Furnace
Sooner or later every homeowner and business owner faces to replace their HVAC system air conditioning and heating. The vast Most people who not plan for when their HVAC air condition and heating system reaches the end of the road. In addition to being uncomfortable temperature-wise, it also becomes uncomfortable financial-wise. They end up calling a contractor or two and get the cheapest city system. Many require at least expensive system does not take into account the future electricity bills, they should pay. A major financial publication had an article listing major appliances and expenses the average homeowner will face in owning a home. They identified how the owners were set aside to replace these things when the average lifespan of the device (or roof) has ended. The average life expectancy for HVAC air conditioning and heating, according to this article, was 13 years. It is a fair assessment of my experience (my notice is 15 years), the more you have to consider the technological leaps that systems can take in thirteen years, including standards of efficiency. Consider a vehicle 15 years old article and how they have been efficient, how many people keep a car for fifteen years? The article gives a figure thirty to forty dollars per month set a board would replace a system financially feasible for anyone. The range for recording $ 30.00 to $ 40.00 per month, more than thirteen years is $ 4680.00 to 6240.00 $. It also seems like a fair assessment to replace an older system with a more recent. It depends what you replace the retro-fit and what you replace. The owner above who could not save this plan $ 30.00 to $ 40.00 per month in energy savings alone by purchasing the more efficient model (which costs more to install). The owner has saved 40, $ 00 per month, could replace their entire system with a more efficient (including duct work) give or take a thousand dollars and savings on their electricity bills. Energy efficiency pays for the conscientious.
January 2006 was the month and year, the Department of Energy (DOE) has raised the bar by changing the rules for air conditioning and pumps heat to raise the SEER 30% from 10 SEER to 13 SEER. The same thing happened in furnaces in the nineties. Manufacturers must sell furnaces that an efficiency rating of at least 78%. Of course with the equipment more efficiently is an increase in replacement cost to the owner / Business. After all, someone must pay for all that research, development, plant retooling, government regulation, re-training technicians and all who helped make the new hi-tech systems successfully.
The new 13 SEER air conditioners owners forced business people and entrepreneurs like to change the entire HVAC system. Before the new rules of the DOE, the contractors could sell you a condenser again and just replace the capacitor. It will not work any longer. A refrigerant 13 SEER 13 SEER will not if you leave the evaporator coil in place of the old system of 10 SEER. It causes mechanical problems that will cause the system not work at all or lead to failure premature for the new capacitor. If a condenser is 10 SEER condemned the indoor coil and the condenser outside, it must be replaced. We will no longer simply the contractor be able to replace the capacitor.
Looking for some years in the future, this same scenario will occur because of another right (or rather a protocol). In 2010, production of the refrigerant R-22 will begin a phase-out period. A good estimate is probably more than 95 percent of homes (not sure about business, but a good guess is that 75 per cent) use equipment which has R-22 in it. To date (April 2006), manufacturers of refrigeration equipment are retooling their factories to begin producing the refrigerant Newest (HFC R-410A) which is legal to produce (without the production restriction that R-22), even after 2010. After 2010, stocks of R-22 are ongoing This will reduce the price to skyrocket. The cost of a pound of R-22 will probably exceed the cost of the call rate service Working at the end of the elimination phase period. History proves that this happens. R-12 and other CFCs have been removed the nineties. The price jumped to very high levels. How high? Some have been caught trying to smuggle across the border with Mexico because it was a lucrative activity, except to go to federal prison, operation. It is a good time now, especially if your system is scheduled for replacement, consider replacing the old R-22 system with the new R-410A systems that are currently available. As the systems 13 SEER, R-410A system will require the replacement of the evaporator coils. In addition, the line-set (copper pipes leading from the outdoor unit to indoor unit) must be replaced. The oil used to lubricate compressor system R-22, which migrates throughout the system, do not mix with the oil used to lubricate the compressor R-410A system. Oil residual in the line-set of R-22 system can cause premature failure of the new R-410A compressor. These are the costs of rules and regulations Government and are based on the Montreal Protocol (Article 2 F: Hydrochlorofluorocarbons) modified by a group of nations including the United States in early nineties.
