Are Goodman Air Conditioners Reliable?

A lot of customers report that Goodman air conditioners are one of the most reliable, and those who have experience with installation say that some 20-25-year-old units still operate! Goodman employs first-rate engineering to provide superior service, and the customers' reviews reflect that!

5 Factors That Affect The Lifespan Of An Air-Conditioner

Certain factors affect the lifespan of an air conditioner; learning these matters, so you can either perform or avoid them. Here they are:

1. Usage pattern

Even good products, if mishandled, break down early. Overstressing your air conditioner results in a damaged compressor, and the costly replacement is the price.

2. Maintenance

Regular maintenance ensures that your air conditioner works as it should and also uncovers minor defects which can deter more serious issues.

3. Location

Location very much affects the lifespan of air conditioners. Units located at the seaside are more susceptible to deterioration. This is because humidity hampers the cooling effect, making the compressor work too hard. 

4. Properly Installing

Incorrect Installation results in leaky air ducts and low airflow. But the frequently related issue in residential places involves incompatible refrigerants.

5. Properly Sizing

Determining the right air conditioner size for your home is a basic rule. The wrong air conditioner size will either lead to an uncomfortable indoor environment or an overworked system.

What Are The Common Problems With Goodman Air Conditioners And How To Fix Them?

No matter how good the craftsmanship is, some technical problems are indeed inevitable. We've listed down some problems you may face with Goodman, particularly as the unit ages:

Low Airflow

This might be due to a clogged duct or filter caused by dust and pet sheds. The Department of Energy says it reduces energy efficiency by up to 15%! Goodman suggests replacing the part if it’s over 90 days, if not, you can try cleaning it. 

Running But Not Cooling

The problem is either the evaporator or condenser coil. They are mainly behind the cooling process. When they malfunction, your AC basically just loses its cooling ability. Periodic cleaning will keep them in good condition. 

Fan Not Working

There are two main reasons why the fan won’t work. First, is bent fin prevents it from spinning. The second is due to ball-bearing failure. Oftentimes, they lead to replacement. 

Not Dehumidifying

Dehumidifying is one primary role of an air conditioner to remove warm air. If it stops absorbing moisture, it might be due to full drain pans. Run a stiff bristle brush through the drains to reset it. 


This is either due to a clogged drain or an overflowing drain pan. Check which one is the culprit to perform the necessary fix. 

Goodman Air conditioner Maintenance

Performing annual maintenance prevents air conditioner emergencies and improves its life expectancy. The good news is, you don’t necessarily have to pay for it every time. There’s DIY maintenance!


This keeps your air ducts clog-free. As a general rule, you should clean the filters after every month or two. It is located behind the cover. Just loosen the latches that hold the front grill to get access to it. Clean it thoroughly then put them back in.  

Exterior AC Unit 

The exterior of the AC can collect foliage, clips, and grass trimmings, so perform a periodic cleaning.


This disperses heat. Ensure that they're straight and dirt-free. Brush off dirt with a clean comb. Just apply light pressure because fins bend easily and the repair is costly. Make sure that the air conditioner is completely off before you access the fins.

Condensate Drains 

It collects humidity. Check it for any debris or buildup. This is located near the exterior unit that is connected to the evaporator coil.

Thermostat Batteries

How Much Do Repair And Maintenance Cost?

The repair and maintenance costs varies depending on the issue and the parts that need to be replaced. But homeowners usually pay between $166 and $600. On the other hand, a high-end repair can cost up to $1,000.  

Signs That Your Air Conditioner Needs Replacement

  • Your AC is over 15 years old. Air conditioners have a lifespan and once they reach that period they start to deteriorate and malfunction.
  • Low energy efficiency. Your electricity bill skyrockets especially during summer despite a high SEER rating on your air conditioner.
  • Frequent repairs. Your air conditioner has been repaired too many times and the total cost outweighs that of the new air conditioner already.
  • High humidity. You have a high humidity level in your home even though the air conditioner is running and the temperature is set on low
  • Recuurring water leaks. Your conditioner produces a pool of water that accumulates in your home.
  • Strange noise. There’s a constant rattling or buzzing noise while your unit operates.

How To Make Your Air Conditioner Last Longer?

Periodic maintenance and not overloading the air conditioner are the best ways to extend its life expectancy.

Annual maintenance already includes a tune-up, ducts and filter cleaning, and leakage inspection. It’s best to schedule pre-season maintenance or before you need the air conditioner at its peak. On the other hand, not overstressing your unit prevents wear and corrosion.  


An air conditioner can last for 10- 15 years. With proper maintenance and usage, you can extend it up to 20 years. Keep in mind that no matter how durable the product if it’s not well-taken care of, it will deteriorate early.
