When deciding between furnace repair in Lawrenceville, GA and replacement, there are a few factors to consider. These are some key things to keep in mind:


AFUE (annual fuel utilization efficiency) is a measure of a furnace’s heating efficiency. If your heating system has an AFUE of less than 80%, you should consider replacing it with a new one that has a higher AFUE. The latest furnaces have AFUE ratings of over 90%. You may also consider retrofitting your heating system, but weigh the cost of a retrofit against the cost of installing a new furnace.

The $5000 Rule

Industry experts often use the $5000 rule to decide between furnace repair and replacement. To use this rule, multiply the age of your heating system by the cost of the repair. If the result exceeds $5000, it may be more cost-effective to replace the furnace. If it doesn’t, you can consider repairing the furnace.

Repair Frequency

If your heating system requires frequent repairs, it may be more cost-effective to replace it rather than continuing to pay for repairs. Frequent repairs can also be inconvenient and lead to poor indoor air quality. If your furnace is experiencing frequent breakdowns, consider getting it inspected by an HVAC contractor in Lawrenceville, GA.


Newer furnaces come with advanced features such as zone-wise heating and smart control, which allow for targeted heating in different areas of the home and easy control from anywhere in the house. If your old furnace lacks these modern features, it may be worth considering a replacement.
