AC Repair or Replace?
should I repair my unit or replace it? Well, like so many things in life, it depends. You might think our answer is always going to be “replace” so you can buy new equipment, but that’s not the case. Sometimes it does make sense to repair a piece of equipment, even if it’s older or if the repair is costly. First, let’s talk about when you probably should consider replacement:
- If you have a standing pilot furnace or an air conditioner that is built before 1992, it’s time to consider replacement, even if you’re not facing a repair. The reality is that your furnace is around 65% efficient and your air conditioner is 8 SEER or less. The amount you can save in utility costs will help pay for the cost of a new unit and it’s not a matter of if, but when you will find yourself facing a costly repair. Take the time now to research and plan for replacing your unit so you have the time to make an educated decision instead of being rushed because you don’t have heating or cooling.
- You have an out of warranty compressor that has failed in your AC or cracked heat exchanger in your furnace. Replacing either of those components is the equivalent of a heart transplant. We do heart transplants for people because we love them and they have value outside of just the cost of the procedure. Machines do not and you shouldn’t spends thousands of dollars repairing the core of an older system that includes lots of other components that are likely to fail or leak within a few years. While making this repair may be less costly than new equipment it is not a decision that I would recommend for the reason I stated above. It’s just not a good investment. Take this opportunity to get new equipment that will save you money in both utility costs and repairs – after all, new equipment comes with new warranties and higher efficiency. Air conditioners also come with environmentally friendly-er refrigerant which has begun to cost much less than the R22 that exists in most air conditioners today.

So those situations are almost always going to be a “Replace” recommendation, but what about when it’s not so obvious?
- Follow one of the many rules of thumb to determine if repairing or replacing makes the most sense for you. Consider replacement if the equipment is beyond three-quarters of its life expectancy and repairs will cost more than a third of replacement. So, if your furnace is 15 years old and you’re facing a $750 AC repair, you should probably replace the unit. Keep in mind that you can also take this opportunity to improve your home comfort and lower your utility bills – in other words, don’t just settle with Single stage 80% furnace and be done with it – consider things like multiple staging, 95% efficiency, and variable speed blowers to maximize your savings and your comfort. Below is a chart that oversimplifies things a little bit, but gives you an idea of what you can expect.
- The best option is to have a highly trained and qualified technician give you an honest assessment of your equipment. Some 10 year old equipment needs to be replaced due to lack of maintenance or a poor quality installation. Some 20 year old equipment looks and works like new because it’s been wellmaintained. A technician knows what to look for and what they’re looking at. If you live in a beautiful newer home but are still stuck with builder’s quality HVAC equipment which has made your home uncomfortable and your utility bills higher than they needed, it might be time to replace your equipment, even if it does have some life left to it. Every situation is different, everyone’s needs are different. Let us help you determine what makes the most sense for your situation.
Some other considerations to help with your decision include knowing how much you could potentially save by replacing your older, less efficient equipment with new high efficiency heating and air conditioning. One tool for that is http://www.hvacopcost.com/ where you can plug in the age, size, and efficiency of your existing equipment, where you live, and what you might replace it with. Try it yourself, you might be surprised by how much you can save.
