Need help deciding? Let's dive in!

Frequency of Repairs

If your HVAC system is constantly breaking down, it might be a sign that it's nearing the end of its lifespan.

Frequent repairs can add up quickly, making it more expensive than simply replacing the system. 

Repairing an old system over and over isn't cost-effective in the long run. 

Replacing the system could save you money on repairs and improve the overall efficiency of your home.

Energy Efficiency

Energy efficiency is an important factor in deciding whether to repair or replace your HVAC system.

If your system isn't running as efficiently as it used to, it could be wasting energy and costing you more money each month.

Replacing an old HVAC system with a newer, energy-efficient model can reduce your energy usage. 

Investing in a new system can pay off in the long run by lowering your energy costs and improving performance.

Type of Repairs Needed

The type of repairs your HVAC system needs can help you decide whether it's worth fixing or time to replace it. 

But if the repairs are more complex, such as replacing the compressor or fixing the motor, the costs can add up quickly.

When major parts of the system need repair or replacement, it might be better to replace the entire unit.

In the long run, investing in a replacement can save you from constant repair costs and keep your home comfortable.

Performance Issues

Performance issues are a clear sign that something is wrong with your HVAC system.

If your system isn't heating or cooling your home as it should, it might be time to check it out.

Weak airflow, uneven temperatures, or rooms that are too hot or too cold can point to underlying problems.

If performance problems are frequent or severe, replacing the system might be a better choice.

A new unit will likely perform better, using less energy and keeping your home at a comfortable temperature.

Fixing performance issues in an old system may only provide a temporary solution, leading to more problems down the road.

High Repair Costs Over Time

If your HVAC system needs frequent repairs, the costs can add up quickly. Over time, paying for repairs can be more expensive than replacing the system.

Constant breakdowns mean you're always spending money to fix problems, which could end up costing more than a new unit.

When repair costs start to rise, it may be time to consider replacement. A new system will likely save you money on repairs and energy bills in the long run.
