Did rising costs of utilities pushed you to think about upgrading or replacing your outdated Heating / Cooling system? Considering that the fuel costs are going to grow – most likely so!

Most of new heating and air conditioner systems are significantly more efficient and less energy consuming than older units and that means $ savings. As of January 2006, all residential air conditioners sold in the United States must have a SEER (Seasonal energy efficiency ratio) of at least 13. ENERGY STAR qualified Central Air Conditioners must have a SEER of at least 14. 20 year old units could have a SEER rating of 7 or 8. Nevertheless, for real savings and efficiency, you should look into how your whole home and especially attic insulated (attic temperature brittle in the winter and extremely hot in the summer). Do that, or your money flow right through the walls & roof. Checking your windows and doors for air leaks is important as well.

Air conditioning systems, are equipped with air filters. Change them at least once a month. These are generally located in main return air duct by the furnace(some models may be washable). A home with pets, or a building with dusty environment, will need to have the filters changed more often than buildings without these dirt loads. If you shall not replace these filters as needed it will a lower heat-exchange rate, resulting in wasted energy, shortened equipment life, and higher energy bills; also low air flow can result in “iced-up” or “iced-over” evaporator coils, and then there is no air flow at all. Very dirty or plugged filters can cause overheating during a heating cycle, and can possibly result in damage to the furnace unit or even fire.

New Heating / Cooling systems are expensive but they worth it. Replacing only your old furnace and/or condenser unit with a new high efficiency furnace and air-conditioning system may not effect efficiency of HVAC system… It is important to have ducts sized correctly in the system, that to ensure sufficient air flow which is correspondent to efficiency gain. Make sure experienced HVAC specialist inspects all the ductwork and supply/return air register sizes .

Poorly designed, ductwork system will waste your money and most likely you will not notice any gain in efficiency and savings by installing a new high efficiency system. I often find duct systems are poorly insulated, damaged or disconnected in attics or crawl spaces during system revisions. Any hot attic air that enters your system through ductwork will be cooled in the summer and heated in the winter time, this increases the load on your system, your wallet and your energy bill.

Don’t forget about evaluation of your ductwork system in your plans are to upgrade your HVAC system. If your will need to revise ductwork system, you might want to consider a high velocity PVC pipe duct system that uses less space.
