The shock of skyrocketing utility bills may have you thinking about updating your HVAC system. What should you learn about these newer A/C systems?
It appears that fuel expenses aren’t going to decreasing any longer. The more recent heating and air conditioning system systems are a lot more effective than older units and utilize significant lasting energy cost savings. The Government has mandated that any cooling systems should have a SEER rating of a minimum of 13 beginning in 2006 and this is excellent, since a twenty-year system may have a SEER rating of just 7 or 8. However, genuine savings, you need to take a look at your entire house as an energy-consuming monster that needs to be placed on a diet plan. This consists of repairing air leaking doors and windows seals.
It does a bit great to alter an older HVAC system and anticipate a great decrease in utility bills if you do not take care of the places where you are losing energy. New A/C systems are expensive and the temptation may be to just install a new high-efficiency furnace and air-conditioning system and hope for the very best. The fact is, the reduction in utility bills may be aggravating due to the fact that you may have ignored a considerable player in the entire HVAC system like the ductwork.
An incorrectly produced, dripping and under-insulated ductwork system can squander 30 percent or more of the money you pay to run your cooling and heating system and nullify any gain you may realize by setting up a brand-new high-efficiency system. Numerous duct systems are incorrectly insulated and leak conditioned air into un-conditioned attics and crawl areas. Professionals typically discover disconnected ductwork throughout various home examinations.
When ducts leak, conditioned air can be displaced unsealed joints and lost. In addition, also un-conditioned air can similarly be drawn into return ducts through unsealed joints. Attic temperature can be exceptionally high in the summer season and cold in the winter. So, any attic air that enters your system through un-sealed duct joints will require to be cooled in the summertime and heated up in the winter season, this increases the load on your system and increases your energy costs.
Remarkably an older house may have a much better-designed duct system than a brand-new home and may just require a leakage check insulation upgrade. More recent homes, on the other hand, maybe a victim of cost-cutting steps and badly developed duct systems.
Making use of flex duct has grown in appeal since ease of setup and the high expense of store made sheet metal ducts. Flex ducts even set up properly are a poor alternative to appropriately developed correctly insulated sheet metal ducts. It dominates practice to make plenums and coil boxes out of the taped-together duct board.
Make certain to include an assessment of your ductwork system in your techniques to update your HVAC system. There is no use in difficult valuable conditioned air to the outdoors through leaks and worn-out duct insulation. If your duct system needs an overhaul, you might want to consider a high-velocity delivery system that utilizes smaller sized PVC pipe ducts. These high-velocity systems are to establish and insulate.
The bottom line on an HVAC system upgrade for optimal performance should include more than just the brand-new equipment. Don’t ignore the ductwork and include it in your budget!
