How to Tell If Your AC Unit Needs Repair or Replacement

Not sure if your AC needs a repair or a full replacement? The key signs include weak airflow, unusual noises, frequent breakdowns, and rising energy costs. In this guide, we’ll help you decide whether to fix your AC or invest in a new one.

Signs Your AC Needs Repair

1. Weak or Warm Airflow

If your AC is running but not cooling effectively, it may have a clogged filter, refrigerant leak, or compressor issue. Schedule a professional inspection with Swift Heating & A/C at (435) 586-4822 to diagnose the problem.

2. Unusual Noises

Banging, rattling, or squealing sounds could indicate a loose part or motor failure. Ignoring these noises may lead to costly repairs.

3. Frequent Cycling or Short Cycling

If your AC turns on and off rapidly, it may be struggling with an airflow restriction or thermostat issue. A professional tune-up can resolve this.

4. Rising Energy Bills

A sudden spike in energy costs without a change in usage often means your AC is working harder than necessary. Upgrading to a high-efficiency unit may save you money in the long run. Learn more from Energy.gov about energy-efficient HVAC options.

Signs It’s Time to Replace Your AC

1. Your AC Is Over 10-15 Years Old

Older units become inefficient and prone to breakdowns. According to the EPA, replacing an outdated unit can improve energy efficiency by 20-40%.

2. Major Repair Costs Exceed 50% of a New Unit

If your repair estimate is half the cost of a new AC, replacement is often the smarter investment. Check average costs on Angi to compare repair vs. replacement expenses.

3. Refrigerant Leaks (R-22 Systems)

If your AC uses R-22 refrigerant, which is being phased out, repairs may become costly. Upgrading to a new system with R-410A refrigerant is recommended.
