How Do I Know If I Need a New HVAC System?

It's not always obvious when your HVAC system needs replacing.

HVAC Installation Tips for Salem Homeowners

Plan ahead. Don't wait for extreme temperatures to consider replacing your system.
Ask about zoning. Controlling temperatures in specific areas of your home can save energy.

Replace air filters. A new HVAC system still needs regular filter changes for optimal performance.

Use smart thermostats. They boost efficiency and let you control your system remotely.

Frequently Asked Questions: HVAC Installation

How often should HVAC systems be replaced?
Most HVAC systems last 10 to 15 years. If your system is older or struggling, it may be time to consider replacement.

Is it better to repair or replace my HVAC?
If repair costs exceed 50% of the price of a new system, replacement is generally more cost-effective in the long run.

What is the $5,000 rule for HVAC?
Multiply your system's age by the repair cost. If the result exceeds $5,000, replacement is typically the smarter investment. For example, a 10-year-old system with a $600 repair totals $6,000, suggesting replacement makes more sense.

Which HVAC brand is most reliable?
Brands like Trane, Carrier, and Lennox consistently rank among the most reliable due to their durability, energy efficiency, and warranty coverage. Cornerstone Services works with top-tier brands to ensure long-lasting comfort.
