AC 4 Life - FAQ's - General Questions

I need to replace just the outdoor/indoor unit of my existing system. What do you suggest?

This page is designed to provide anyone looking for a new HVAC system with a better understanding of frequently asked questions about the selection, AC and furnace sizing and other important considerations in making the best choices for your home or office.

This information guide offers the following categories of information pertaining to proper AC and heating system sizing as well as important guides to ensure you make informed decisions:

If you have a gas heating and central air conditioner, the outdoor unit can normally be replaced without changing the indoor section. You will need the existing outdoor unit capacity (tonnage) to determine the proper replacement.

All manufacturers recommend a matched indoor coil as well for proper efficiency but, in reality, people replace existing outdoor units and normally don't experience problems. The system may not function to full capacity and efficiency but if this is all your budget allows then it is an option.

If you have a heat pump split system, replacing just the outdoor may cause a refrigerant imbalance in the heating mode. No one can tell you in advance whether any particular replacement unit will work (unless it is an identical replacement). The odds are in your favor that it will work but if there is a problem, be prepared to replace the indoor unit.

As a general rule, if your system is over 10 years old and you experience a major failure a new high efficiency system may be less expensive in the long run.
