Signs It Might Be Time for a Replacement

Frequent Breakdowns & High Repair Costs

If your AC is over 10 years old or your furnace is older than 15, and you’re constantly calling for repairs, it may be time to rethink. Once repairs exceed 50% of the cost of new equipment, investing in a replacement makes more financial sense. A professional evaluation from Savage Air Conditioning can give you peace of mind and clarity.

Rising Energy Bills & Declining Efficiency

An older HVAC system can lose 10–25% of its efficiency over time. AC units generally drop off after 10–15 years, while furnaces lose efficiency after 15–30 years. High-efficiency SEER-rated ACs and AFUE-rated furnaces are not only budget-friendly over the long run, but they also improve your home’s comfort. Our licensed HVAC pros can help you identify the best energy-saving upgrade for your home.

Mismatched System Components

Upgrading just your AC while keeping an old furnace can lead to system incompatibility. Things like fan motor speeds, voltage, and efficiency ratings (SEER/AFUE) need to align. Let our professionals assess your current setup to ensure all parts work smoothly together.

Should You Replace Both the AC & Furnace?

Pros of Replacing Both Units Together

  • Cost savings from bundled labor and equipment
  • Improved efficiency with fully compatible systems
  • Single warranty coverage for both units
  • Avoid future disruption from staggered replacements

Potential Cons

  • Higher upfront cost
  • May not be necessary if one system is still newer and performing well

We recommend a complete inspection by our certified technicians before making the decision. If your AC is 10+ years old and the furnace 15+, it might be smarter to replace both, but let our team walk you through your best options.

Not Sure What to Do? Here’s What We Recommend

Start with a comprehensive HVAC inspection from Savage Air Conditioning. We’ll evaluate the age, performance, and compatibility of your existing systems. Whether you replace one unit or both, we’ll help you compare costs, explore available Arizona rebates, and look at financing options designed to fit your budget.

Prevent Major Replacements With Routine Maintenance

Seasonal HVAC tune-ups restore lost efficiency, ensure airflow, and detect problems early. Regular maintenance performed by our certified technicians helps your system run smoothly and reduces the risk of unexpected breakdowns. Skipping tune-ups can reduce your system’s efficiency by up to 25%, according to the Department of Energy.

FAQs: AC & Furnace Replacement in Tempe

How much does a full HVAC replacement cost in Tempe, AZ?

Between $6,500 and $12,500 depending on unit size, efficiency, and installation complexity.

Can I replace just the AC if my furnace is newer?

Yes, if the furnace is under 10 years old, in good condition, and under warranty. But always check for system compatibility first.

What efficiency ratings should I look for?

In Tempe’s climate, aim for a SEER rating of 16+ for AC units and an AFUE of 90+ for furnaces. We can help you find the best fit.
