A Complete Guide: Deciding Whether to Repair or Replace Your HVAC System

Should you opt for an HVAC system repair or replace the system? Fixing the system is cheaper than replacing it and can keep heating and cooling working for a bit longer. But a new system can save you money on energy bills every month. This guide will help you decide.

When to Fix Your HVAC System

Age of the System

The age of the system is a good starting point. General lifespans for HVAC systems:

• Air conditioners: 15–20 years
• Furnaces: 15–20 years
• Heat pumps: 15 years

If the system is less than 15 years old, you should probably consider fixing it if it breaks down.

Warranty

If the system is still under warranty, the warranty should cover the cost of repairs. If the warranty is gone, you'll have to pay for the repairs yourself. Replacing the system might be a better option if it's old, not very efficient, or breaks down frequently.

Cost of Repairs

A simple rule to help you decide: multiply the age of the system by the cost of the repair. If the answer is less than $5,000, fixing the system might be a good option. If the answer is more than $5,000, replacing the system might be a better choice.

Repairs that might mean it's time to replace, especially if not under warranty:

• Replacing the evaporator coil
• Replacing the compressor
• Replacing the condenser fan motor
• Fixing a refrigerant leak

When to Replace the HVAC System

System Efficiency

Older systems lose efficiency over time. Systems made even ten years ago are far less efficient than today's models. For air conditioners, the efficiency is measured by the SEER rating — if the old AC has a SEER rating below 10, consider replacing it. Replacing a SEER 9 unit with a SEER 14 can save you more than 35% on energy costs.

Financial Incentives

The government sometimes offers tax credits or rebates to help you buy a new, energy-efficient heating and cooling system. There are currently tax credits available for heat pumps.

Moving Plans

If you plan on moving in the next few years, it might not make sense to replace an HVAC unless it breaks down completely. But if you plan on staying in the same home for a while, a new energy-efficient system can save you money and keep your home comfortable for years.

Environmental Considerations

If you're concerned about the environment, replacing an old system is a good option, especially if it's 10–15 years old. New furnaces and air conditioners are much more efficient, lowering your carbon footprint. Heat pumps can also be a good option because they use electricity and refrigerant to move heat instead of relying on fossil fuels.

Conclusion

Deciding whether to repair or replace your HVAC system depends on a number of factors. Talk to an expert HVAC repair service and consider all of these factors to make the best decision for your home and your wallet.
