Repair or Replace?

We get asked this question all the time - should I repair my unit or replace it? Well, like so many things in life, it depends. As an HVAC contractor, 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 more sense to repair a piece of equipment, even if it's older or if the repair is costly.


  • If you have a standing pilot furnace or an air conditioner that is built before 2000, 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. You shouldn't spend 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 now also come with refrigerant that is more environmentally friendly and has begun to cost much less than the R22 that exists in most preexisting air conditioners today.


  • 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 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 well maintained. 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.
