Repairing vs. Replacing Your Furnace: How to Decide
It can be tough to know whether to invest in another furnace repair or move forward with a new system.
Here are key factors to consider:
- Your furnace's age. If it's 15 years or older, replacement often makes more financial sense.
- Frequency of repairs. Multiple service calls in a single season indicate your furnace is nearing the end of its lifespan.
- Comfort issues. Uneven heating, constant cycling, or rooms that never stay warm may point to a system that's too old to perform efficiently.
- Repair costs. If the repair costs more than half the price of a new system, it's time to upgrade.
Still need direction? We have you covered. Our team can assess your existing system’s condition and provide an honest recommendation for the best path forward.

Brian was very friendly and knowledgeable. He explained the problem, our options, and what his recommendations were. He worked very fast, too, and we ended up paying a little less than what was originally estimated. He also made sure everything was put back together and even cleaned up afterwards. We are very happy with his service and appreciate his professionalism. We’ll definitely look to Intelligent Service again for any plumbing issues. Thank you so much! -
