Upgrading Your HVAC System
The shock of skyrocketing utility bills may have you thinking of updating your HVAC system. What should you understand about these more recent HEATING AND COOLING systems?
It appears that fuel costs aren’t going to decreasing any longer. The more current heating and a/c system systems are a lot more efficient than older systems and use substantial long-lasting energy cost savings. The Federal government has actually mandated that any cooling systems must have a SEER rating of a minimum of 13 beginning in 2006 and this is outstanding, due to the fact that a twenty-year system might have a SEER rating of just 7 or 8. However, for real savings, you must have a look at your whole home as an energy eating beast that requires to be placed on a diet strategy. This consists of repairing air leaking windows and door seals.
It does a bit good to change an older HVAC system and anticipate a great decrease in utility bills if you do not look after the places where you are losing energy. New HEATING AND COOLING systems are costly and the temptation may be to just install a new high-efficiency furnace and air-conditioning system and wish for the best. The fact is, the decline in utility bills might be frustrating because you might have ignored a considerable gamer in the entire HVAC system like the ductwork.
A poorly produced, dripping and under-insulated ductwork system can lose 30 percent or more of the money you pay to run your cooling and heating system and nullify any gain you might recognize by establishing a new high-efficiency system. Many duct systems are incorrectly insulated and leak conditioned air into un-conditioned attics and crawl areas. Experts typically discover detached ductwork throughout various home evaluations.
When ducts leak, conditioned air can be displaced unsealed joints and lost. In addition, also un-conditioned air can also be drawn into return ducts through unsealed joints. Attic temperature level can be exceptionally high in the summertime and cold in the winter season. So, any attic air that enters your system through un-sealed duct joints will need to be cooled in the summer and heated in the winter, this increases the load on your system and increases your energy bill.
Remarkably an older home may have a much better-designed duct system than a brand-new home and may simply require a leak check insulation upgrade. More current houses, on the other hand, might be a victim of cost-cutting measures and severely developed duct systems.
Utilizing flex duct has actually grown in appeal due to the fact that ease of installation and the high expenditure of store made sheet metal ducts. Flex ducts even established effectively are a poor alternative to effectively developed properly insulated sheet metal ducts. It prevails practice to make plenums and coil boxes out of the taped-together duct board.
Ensure to consist of an assessment of your ductwork system in your strategies to update your HVAC system. There is no use in difficult valuable conditioned air to the outdoors through leakages and damaged duct insulation. If your duct system requires an overhaul, you might wish to consider a high-velocity shipment system that utilizes smaller sized PVC pipeline ducts. These high-velocity systems are to set up and insulate.
The bottom line on an HVAC system upgrade for optimal effectiveness should consist of more than simply the new equipment. Do not forget the ductwork and include it in your budget!
