Replacement Planning
Repair it again, or replace it.
This decision gets made badly, and usually in August, in a hot house, by whoever is standing in front of you. The pressure is real and so is the discomfort, and neither one improves the decision.
It is a decision that can be made in advance, calmly, with actual information about the system you have.
What should drive the decision
Not age by itself. A well installed system in good condition can run long past the number people quote, and a badly installed one can be finished early.
The questions that matter: what is the measured condition of the equipment right now, what is the failure pattern, what does the rest of the system look like, and what would a replacement actually cost to do correctly in this house.
That last one is where most of the surprise lives. If the duct system cannot support what is there now, new equipment does not change that, and a replacement that ignores it produces an expensive system with the old complaints.
The repair math
The useful version is not a formula. It is whether this repair buys you a system with predictable life left, or whether it buys you a few months before the next one.
A compressor failure on an older system, a leak in a coil that has already been repaired, or repeated failures of the same component are the cases where repair spending stops compounding in your favor. A capacitor on a system that has measured well for years is not that case.
Replacement is a design decision, not a shopping decision
A replacement done correctly starts with what the house actually requires, not with what is currently installed. Swapping equipment for equipment of the same nameplate size perpetuates whatever was wrong with the original installation, including oversizing, which is the source of most humidity complaints in this region.
We do the assessment that establishes what the house needs before anything gets specified.
Deciding before you have to
The best time to work this out is a season ahead, when the system is still running and you have the option of doing nothing. Decisions made under a failure are decisions made under pressure.
Common questions
Common questions
- How long should a system last?
- Long enough that the answer is not useful for your specific system. Condition is knowable. An average is not a prediction.
- Is it worth repairing an old system?
- Sometimes clearly yes, sometimes clearly no, and the difference is the measured condition rather than the year on the data plate.
- Will you push me toward replacement?
- The evaluation is a separate product from any work that follows it, which is the structural reason we have no reason to. We will tell you when repair is the better spend.
- Can I take your findings to another contractor?
- Yes. It is your report.
