## AC condenser FAQs

### What is an AC condenser coil?

An AC condenser coil works with an evaporator coil to remove heat from the home's air and release it outside.

Steps of the AC cooling cycle:

1. Liquid refrigerant cools the indoor evaporator coil.

2. The cooled evaporator coil absorbs heat from the home's airflow and transfers it to the outside condenser unit through a copper line.

3. A compressor converts the heated gas back to liquid form in the condenser coil.

4. The refrigerant releases the heat outside as it changes from gas to liquid.

5. The cooled refrigerant then travels back to the evaporator coil to begin the cycle again.

### What size AC condenser unit do I need?

The new AC condenser should match the size of the current unit. To find your existing condenser's size:

1. Find the condenser's model number on the label.

2. Divide the 2-digit number within the condenser's model number by 12 to get the ton size.

Replacing the entire AC system is required if updating to a larger condenser unit.

### How long do AC condensers last?

AC condensers last 10 to 20 years. Factors that affect an AC condenser's lifespan include:

• Climate and usage – AC systems in northern states typically run for 1 to 3 months per year, while AC's in southern homes may run for 10 months or more.

• Proper maintenance – Routing filter changes and annual tune-ups prolong the AC's life.

• Correct AC sizing – An improperly sized unit cycles on and off more often, reducing the AC's lifespan.

### How long does it take to replace an AC condenser?

Replacing an AC condenser takes 4 to 8 hours. The unit size and AC system type affect the installation time. Larger condenser units take longer to install than smaller-sized units.

### Should I repair or replace my AC condenser?

Consider replacing the whole AC system instead of repairing the condenser if:

• The AC unit is more than 10 years old.

• The condenser is no longer under warranty.

• Repairing the condenser costs 50% or more of the cost of a new AC.

• The system uses R-22 freon. Replacing a condenser unit that uses R-22 refrigerant requires replacing the indoor unit at the same time.

### Do home warranties cover AC coils?

Most home warranties cover the HVAC system, which includes the AC coils. The homeowner is typically responsible for the service call fee. Always confirm the coverage details within your policy, as home warranties vary by company and location.

### Where is the condenser coil located?

The condenser coil is located in the outdoor AC condenser unit behind the thin metal wiring or "fins."

## Getting AC condenser coil replacement cost estimates

Before hiring an AC repair service, be sure to:

• Confirm whether the condenser is covered by a manufacturer's warranty.

• Get at least three estimates with comparable equipment to compare.

• Look for a NATE-certified technician with experience in AC condenser repair and replacement.

• Browse their reviews on HomeGuide and Google.

• Select companies that are insured, bonded, and have been in business for 5+ years.

• Avoid selecting the lowest quote as quality may suffer.

• Get a detailed estimate, contract, and warranty in writing before the work begins.

• Never pay in full before the project starts. Use a payment plan instead for work completed.

• Are you licensed, bonded, and insured?

• Are you NATE-certified?

• What experience do you have with AC condenser repair?

• Is it better to repair or replace the condenser, and why?

• Do I need to replace the indoor unit at the same time?

• What size AC condenser do I need?

• What is and is not included in the estimate?

• What additional costs should I expect?

• How long will the repair or replacement take?

• How long should new AC condenser last?

• Is there a warranty? If yes, what does it include?
