Younits Helps Upgrading Central Air Conditioning Units

June 3, 2013

With the changing of seasons from cold to hot, it’s time to turn on the air conditioning units. For some, it may be time to upgrade.

Schaumburg, Illinois (PRWEB) June 03, 2013

Central air conditioning units are one part of what is commonly referred to as a complete split system, which is comprised of an outdoor and indoor unit, as well as an evaporator coil (usually located on top of the indoor unit). Outdoor units are either air conditioners (cooling only) or heat pumps (heating and cooling). Indoor units are either air handlers (blowers with coil) or furnaces (gas with heating elements). Younits has a complete selection of central split systems.

Air conditioners direct refrigerant to the evaporator coil; the coil then uses the chilled refrigerant to cool the air sent from the indoor unit. The cooled air is returned to the ducting to be distributed through the space.

When replacing an air conditioner, there are a few things to consider. Central air conditioning units should be serviced yearly before the cooling season begins. If the system is aging, consider replacing it before it dies. This way, making informed decisions regarding cooling needs now rather than having to quickly replace it in the middle of the summer will set a person’s mind at ease.

Younits Tips for Upgrading:

  •     Better Efficiency. Since 2006, the minimum SEER (seasonal energy efficiency ratio) rating for central air conditioning units is 13. Older air conditioners had a minimum SEER rating of 10 (or less depending on the age of the system), so upgrading to a new model with at least the minimum SEER rating will significantly reduce energy consumption costs.
  •     Ducting. If the central air conditioner hasn´t been upgraded for a while, it is likely that the ducting hasn´t either. Have the ducting checked to see if it needs to be repaired or replaced. It should be adequately insulated to prevent air loss, which translates to a loss of efficiency or more money out of the pocket in energy costs.
  •     Matching the Indoor Unit. A person may replace the entire split system, or replace only the outdoor condensing unit, commonly referred to as the central air conditioner. If they decide to replace only the condensor, they should consult with a contractor to make sure the condensor that will be purchased is compatible with the existing indoor unit. If the entire system is old, it may be more cost effective to replace all of the components.
  •     R410a vs. R22. When replacing the entire split system, the new system will run on R410a refrigerant, which is non-ozone depleting. If existing system runs on R22 refrigerant, there are options to consider. Basically, either replace only the condensing/outdoor unit with a new one that uses R22, or replace both the condensor and the evaporator coil with units that both run on R410a. It is impossible to use an R410a condensor with an R22 coil. In the case of staying with R22 refrigerant, the contractor will need to charge the system with R22 that is field supplied. In most cases, the R22 refrigerant from the old condensing unit can be recovered by the contractor and reused in the new system. However, it is recommended when possible to switch to R410a equipment when upgrading; R22 will not be produced after 2020. R410a systems are more efficient and come pre-charged, so the contractor simply has to release the refrigerant into the system.
  •     Sizing the System. While usually the new central air conditioner will be the same size as the current one, it is a good idea to have a contractor evaluate whether the current system is adequately cooling the space or not. Is the central AC unit running constantly? It may be undersized. Does the air cool but still feel humid? The air conditioner may be too large.
  •     Qualifying for Rebates. When upgrading to a central ac unit that is Energy Star rated and/or has a high SEER rating, the consumer may be eligible for rebates or tax credits. This can often substantially offset the initial higher cost of purchasing such a system. Check out Energy.gov or go to Dsireusa.org for information regarding eligibility.

Newer air conditioners are more efficient, environmentally friendly and have a quieter operation than older systems. Once the decision to upgrade has been made, it will be the time to consider the different options available, including motor speed, stages and SEER ratings.
