Is It Time To Replace Or Repair My HVAC?

Old and dirty GREE and LG external AC units.Modern air conditioning has become essential for summer comfort. However, every system eventually requires professional attention—whether repair or replacement. Here are the key indicators to help you decide which service you need.

Signs You Need HVAC Service

1. Dirty Air Filters

Your AC’s air filters play a critical role in:

  • Trapping pollen, dust, and airborne particles
  • Maintaining indoor air quality
  • Protecting system components

While you can clean or replace filters yourself, persistent issues require professional AC repair services.

2. Warm Air From Vents

If your system blows warm air during peak summer, potential causes include:

  • Frozen evaporator coils (recurring ice buildup after defrosting suggests replacement)
  • Clogged condenser unit (may need professional cleaning or repair)
  • Refrigerant leaks

3. Rising Energy Bills

Sudden cost increases often indicate:

  • Failing components working harder
  • Reduced efficiency
  • Ductwork leaks

Schedule an HVAC inspection to diagnose the issue.

4. Uneven Cooling

Temperature inconsistencies may stem from:

  • Faulty ductwork (duct services)
  • Aging equipment
  • Improperly sized system

5. Advanced Age (15+ Years)

While well-maintained systems last 15-20 years, older units:

  • Become less efficient
  • Require frequent repairs
  • Use outdated technology

Replacement becomes mandatory when you notice: frequent breakdowns (more than twice annually), visible rust/decay, refrigerant leaks (R-22 systems), or if your system no longer maintains temperature consistently.

Consider replacement options if repair costs exceed 50% of a new system’s price.

6. Unusual Noises

Different sounds indicate specific problems:

  • Screeching: Belt or motor issues
  • Banging: Loose or broken parts
  • Gurgling: Refrigerant leaks

These often require immediate professional attention.

Making the Right Choice

While repairs cost less upfront, replacement may be smarter when:

✔ Repairs exceed $500 annually
✔ Your system is over 10 years old
✔ Energy bills keep increasing
✔ Comfort issues persist
