When to Replace Your HVAC System: A Guide for Burbank & Oak Lawn Homeowners

Deciding whether to repair or replace your HVAC system is one of the most important home comfort decisions you'll make. Here's what Southwest Chicago homeowners need to know.

How Long Should an HVAC System Last?

Typical lifespans:

• Central AC: 12-17 years
• Furnace (gas): 15-20 years
• Heat pump: 12-15 years
• Boiler: 15-25 years

However, systems in homes with poor maintenance or restrictive ductwork may fail earlier. Regular tune-ups can extend equipment life by 3-5 years.

7 Signs It's Time to Replace

1. Your System is 12+ Years Old and Needs Major Repairs

If your AC or furnace is approaching the end of its lifespan and requires a repair costing more than 50% of replacement value, replacement usually makes financial sense.

Major repairs include:

• Compressor or heat exchanger replacement
• Complete evaporator coil replacement
• Multiple simultaneous component failures

2. Rising Energy Bills

If your utility bills have increased 20-30% with no change in usage, your system is likely losing efficiency. Older systems can cost $500-1,200 more per year to operate than modern high-efficiency models.

3. Uneven Temperatures Between Rooms

Hot upstairs in summer and cold in winter? This could indicate:

• Undersized or failing equipment
• Ductwork problems
• Poor system balancing

A new properly-sized system with ductwork upgrades can solve these issues permanently.

4. Frequent Repairs

If you're calling for repairs 2-3 times per year, you're likely spending $400-800 annually on bandaid fixes. That money is better invested in a reliable new system with warranty coverage.

5. Excessive Noise

Loud banging, squealing, or grinding sounds often indicate failing motors, bearings, or compressors—expensive repairs that may not be worth it on an aging system.

6. Your System Uses R-22 Refrigerant

R-22 (Freon) was phased out in 2020. If your AC needs refrigerant, you're facing expensive R-22 costs or mandatory system replacement.

7. Poor Indoor Air Quality

Older systems may struggle to control humidity and filter allergens. Modern HVAC systems with variable-speed blowers and advanced filtration dramatically improve indoor air quality.

Repair vs. Replace: The 50% Rule

Use this simple formula:

(Cost of Repair) × (Age of System in Years) = Decision Number

• If the result is less than $5,000, repair is usually wise
• If the result is more than $5,000, replace

Example:

• Repair cost: $800
• System age: 14 years
• Calculation: $800 × 14 = $11,200
• Recommendation: Replace

Benefits of Modern High-Efficiency Systems
