Should I repair or replace my equipment?
First, you need to consider the age of your current system. If your system is more than 10 years old, it may be wiser to upgrading to a higher efficiency system to save on energy costs and repair bills.
Second, you need to consider the overall condition of your current system. Are you adding refrigerant every year, or twice a year? Is it costing more to keep your system running than the energy savings you would receive from a newer, high efficiency system.
Third, you need to consider factors unique to you. Will you be moving soon? Will a new system add value to your home? Will you be in your home long enough to reap all the benefits a new system brings? Is there anyone in your home that must have a reliable indoor home comfort system at all times (elderly, sick, children)?
If at any point your current system is costing you more to repair than a new system would save or if it would improve your homes value or your family's health, it is time to consider replacing your system.
