Signs You Need an Air Conditioner Replacement

Most air conditioners have a lifespan of 20 years. However, with regular maintenance, they can live much longer beyond their years.

Is your air conditioner not blowing cold air, inefficient, or in need of constant repairs? These are some of the signs you will probably need a replacement sometime soon. 

If homeowners still have R-22 refrigerant, it is a good indicator to consider replacement. R-22 was phased out the beginning of 2010, and the government has set 2020 as the year all R-22 will be completely banned. Currently, if an R-22 system has a refrigerant leak, it likely will need to be replaced. 

Minor repairs such as a blown fuse and breaker can likely be repaired, but eventually, the system will need replacement. 


air-conditioner-2361907_1920If a system is 15 years or older and begins needing repairs, or has not been properly maintained, it might be time for a replacement. Although systems can function for 20 plus years, running them often, not maintaining them, or improperly sized units will wear down at a faster rate. If the system requires a major repair, it might be worth it to replace it with a higher efficiency system, as more repairs are imminent. 


When the compressor is out of warranty, homeowners should think about a replacement. A standard compressor warranty is ten years. If it is older than ten years, and in need of replacement, it would be wiser to replace the whole system. There is a 30 percent failure rate when the compressor is replaced and could end up costing homeowners more money in the future. 

Once a HVAC technician opens up factory seals and the refrigerant components, it compromises the system as a whole.


With regular maintenance, a home air conditioning system should last at least 20 years, and can often be more. Depending on the type of system you have, check to see how often you should change the AC filter and how often you should clean the air ducts for regular maintenance. If a system has not had regular annual maintenance and is older, it is time to replace with an energy efficient system and set up preventative maintenance. 

Manufacturers advise that a home air conditioning system will last 20 years with regular maintenance. Regular maintenance means one visit for the air conditioner in the Spring before it will be heavily used and once in the Fall before the cold winter months. 

Refrigerant Leaks

outdoors-3290142_1920Sometimes refrigerant leaks mean a simple repair. For instance, if the refrigerant is leaking from a copper line or a u tube, it is a simple repair. However, if it is in the coil, the entire coil would need to be replaced. 

All in all, when it is time to replace a home air conditioning system, it is often a considerable investment and a decision of which homeowners should weigh all options. 

Many homeowners choose to think about replacing their air conditioning system due to failure of the unit, or when the cost of repairs does not make sense versus upgrading to an energy efficient system. Sometimes, homeowners want to upgrade their old inefficient system to a newer high-efficiency air conditioner. Over time, the cost to replace can be offset by lower energy costs to run the system. 

When is the Best Time to Upgrade Your Air Conditioning System?

In San Diego, the best time to upgrade your old inefficient system is in the spring before the heat wave hits. Because many HVAC repair and installation companies will have extra inventory, or lower volume of calls when air conditioners are not being run often, they can offer special deals and discounts. 

Regardless of when you find yourself in need of a new air conditioner, there are a number of reasons to think about an air conditioner capacitor replacement.

What David says about us

Service for new garbage disposal. My ancient garbage disposal quit working, went online to get Bill Howe’s number, immediately received and accepted chat to describe my needs. Prompt call back to schedule an appointment, service tech Allen was out same morning, which was important to fit my work schedule. Job estimate was clear, work done fully to my expectations, area left clean, and price was very fair.
I was not surprised — I have used Bill Howe plumbers for several other tasks in the past. I have always found their staff to be helpful, attentive, and the plumbers very courteous and capable.

What Mira says about us

Bill Howe never fails us! We had a drain overflow, and Scott came (on a Saturday) to look at it and offer solution. He was punctual, professional, and extremely helpful. I should also praise the main office for always being helpful and always finding solutions. Very grateful to have you in San Diego!

Cory was our technician on this job. We had a time sensitive repair issue and Bill Howe understood and assisted with getting the job done quickly.
Cory was on time to start the job and finished it quickly. Upon his leaving our home he’s was courteous, very knowledgeable, explaining what the problem was and how he fixed it. Very good communication and this is the way it’s has always been when we use Bill Howe plumbing.
Great company to work with.
Thanks Cory.

What Bridgett says about us

I am extremely happy with the service we received from Bill Howe Plumbing. We were given an incorrect diagnosis of our main sewer line from another vendor, but Bill Howe’s servicemen came out for a second opinion, correctly diagnosed our problem and resolved our back up issues. We will continue to use Bill Howe for all our future plumbing needs!

Thank you Bill Howe Plumbing.
