When your heating or air conditioning stops working, the first question is usually pretty simple:

Can you fix it?

But especially as your equipment gets older, there’s another question worth asking:

Should you?

At Crabbe Service Company, we don’t believe an HVAC system automatically needs to be replaced because it reaches a certain age. We’ve repaired older systems that still had useful life left. We’ve also encountered relatively young equipment where improper installation or repeated problems made replacement the better option.

The decision comes down to more than a number on the equipment label.

Age matters. So does the cost of the repair, the condition of the equipment, its maintenance and repair history, whether it’s still under warranty, and what else may need attention in the years ahead.

Most importantly, the right answer depends on your situation.

Here’s how we help homeowners think through the decision.

How Long Do HVAC Systems Last? 

When homeowners ask us about HVAC life expectancy, we generally tell them that 12 to 15 years is a reasonable expectation for a heating and cooling system.

That doesn’t mean your system suddenly becomes obsolete on its 12th birthday.

Some equipment lasts considerably longer. Other systems experience major problems much earlier. How the equipment was originally installed, how it has been maintained, and what it has experienced throughout its life can all affect how long an HVAC system lasts.

That’s why we don’t believe in automatically recommending replacement once equipment reaches 10 years old.

If an older system is otherwise in good condition and needs a reasonable repair, fixing it may give the homeowner more useful years without the expense of replacing the entire system.

On the other hand, age becomes increasingly important when major repairs start adding up.

Repair vs. Replace HVAC: Look Beyond Today’s Repair 

A broken component tells us what’s wrong today.

It doesn’t necessarily tell us what could happen six months from now.

That’s one of the most important things we consider when deciding whether to repair or replace HVAC equipment.

Suppose a major component on the cooling side of an older system fails. We may be able to replace it and get the air conditioning running again. But before asking you to make that investment, we also want to consider the condition of the heating side and other major components.

If another expensive component is already showing signs of deterioration, spending thousands on today’s repair could leave you facing another substantial bill shortly afterward.

At that point, the money spent on multiple repairs may have been better invested in a new system with a new warranty.

That doesn’t mean another failure is guaranteed. HVAC equipment is mechanical equipment, and nobody can predict exactly when something will break.

What we can do is tell you what we see.

If we notice something that could become another problem, we’d rather explain it before you approve the repair than have it come as a surprise later.

Some HVAC Repairs Change the Conversation More Than Others 

Not every repair is a reason to consider replacing your system.

Motors, relays, and other smaller components are common HVAC repairs. Even on older equipment, replacing one of those parts doesn’t necessarily mean it’s time to start over.

Major components are different.

A failed compressor, condenser coil, or evaporator coil can represent a much larger investment. When one of those components fails on older equipment, that’s when we generally think it’s worth discussing both options.

The condition of the rest of the system matters too.

For example, if we’re investigating a failed compressor on a system with gas heat, we may also inspect the heat exchanger while we’re inside the equipment. If it’s showing significant deterioration, that’s something you need to know before investing heavily in the cooling side of the same system.

The goal isn’t to find reasons to sell you new equipment.

It’s to make sure you understand what you’re putting money into.

When Does an HVAC Repair Cost Too Much? 

There’s no dollar amount that automatically makes an HVAC repair a bad investment.

We don’t use a rule that says a repair costing a certain percentage of a new system means you should replace the equipment.

Why?

Because we don’t know what someone else’s budget looks like.

A homeowner may be comfortable investing several thousand dollars in a repair. Someone else may need to minimize today’s expense as much as possible.

Instead, we look at what that repair buys you.

Is the equipment still under the manufacturer’s parts warranty?

Has the system been reliable until now?

Have you already made a substantial investment in another major component?

Are problems becoming repetitive?

What condition is the rest of the equipment in?

Those questions give us much more useful information than an arbitrary dollar threshold.

Previous repairs can even make another repair more reasonable in some circumstances.

If you invested substantially in a compressor a couple of years ago, for example, we’re going to look carefully at whether a new problem can be repaired reasonably so you can continue getting value from the investment you’ve already made.

When to Replace Your Heating and Air Conditioning System 

Sometimes the equipment can technically be repaired, but replacement still deserves serious consideration.

We tend to have that conversation when several factors begin stacking up:

• The system is older and outside its parts warranty.
• A compressor, condenser coil, evaporator coil, or another major component has failed.
• Repairs have become repetitive.
• Other expensive components are showing signs of deterioration.
• Replacement parts or the refrigerant used by the equipment are becoming difficult or expensive to obtain.
• The system wasn’t installed properly and correcting the problems would require significant additional work.
• The equipment is no longer meeting the home’s comfort needs.

No single item on that list automatically means you need a new system.

It’s the overall picture we’re interested in.

An older HVAC system that has been dependable and needs one manageable repair presents a very different decision from an equally old system that has needed attention every year.

Comfort Problems Matter Too 

Repair history isn’t the only reason to evaluate an aging HVAC system.

Maybe the equipment still runs, but you’re struggling with uneven temperatures. Perhaps it runs excessively, cycles frequently, has difficulty controlling humidity, makes more noise than it used to, or simply doesn’t keep the house as comfortable as you’d like.

Those issues deserve investigation.

But we also don’t want to blame the HVAC equipment for every comfort problem or every high utility bill.

Sometimes the problem is somewhere else.

If several sections of ductwork have become disconnected beneath the house, for example, conditioned air may be going into the crawlspace instead of the rooms you’re trying to heat or cool. In that situation, replacing perfectly serviceable HVAC equipment wouldn’t address the real problem.

That’s why troubleshooting comes before recommending equipment.

Replacement Can Be an Opportunity to Fix More Than a Breakdown 

When replacement does make sense, it gives us an opportunity to look at the heating and cooling system as a whole.

Maybe you’d benefit from better efficiency or quieter operation.

Maybe the duct design could be improved.

Maybe one part of your home has always needed more heating or cooling than another.

Or perhaps the existing system was improperly sized or installed in the first place.

Rather than simply replacing one piece of equipment with another, we can evaluate whether there are opportunities to improve how the entire home is heated and cooled.

That’s particularly important if your home itself is changing.

If you’re renovating, changing the layout, or building an addition, we’ll consider whether the existing equipment can accommodate the additional space, whether another system would make more sense, or whether it’s an appropriate time to replace and resize the existing system.

Sometimes the Right Repair or Replace Decision Has Nothing to Do With the Equipment 

Two homeowners could have essentially the same HVAC system with the same problem and reasonably make different decisions.

Someone planning to stay in their home for another 15 years may value the efficiency, comfort, reliability, and warranty that come with replacement.

Someone preparing to sell in six months may have completely different priorities.

Budget matters too.

We don’t assume what you can afford or tell you how you should spend your money. Our job is to help you understand what you’re buying with either decision.

Sometimes an Older HVAC System Is Still Worth Fixing 

We recently worked with a homeowner who was tired of repeatedly having refrigerant added to an older system.

The equipment was out of warranty, and after dealing with the same issue year after year, the homeowner was ready to replace it.

But the system hadn’t actually been checked to determine why it was losing refrigerant.

We offered to perform a leak search, found the source of the problem, and were able to repair it and recharge the system.

Instead of automatically replacing the equipment, we found a repair that could allow the homeowner to keep using what they already had.

The opposite can happen too.

Repeatedly operating a system that’s low on refrigerant can put additional strain on the compressor. If the homeowner has dealt with recurring refrigerant problems and the equipment has already been stressed as a result, replacing the system may eventually become the more sensible investment.

Same symptom.

Different circumstances.

Different answer.

Before You Repair or Replace Your HVAC System, Understand Your Options 

Perhaps the biggest mistake in the repair-or-replace decision isn’t choosing the “wrong” option.

It’s making the decision without understanding what could come next.

Spending money on a repair and having another major component fail six months later is frustrating. That’s especially true when the money spent on the first repair could have gone toward a new system.

That’s why Crabbe Service Company doesn’t believe in making the decision for you.

When repair and replacement are both reasonable options, we’ll explain the pros and cons and price those options so you can compare them. If you ask what we’d do in the same situation, we’ll tell you.

And if you choose to repair an older system after we’ve recommended replacement, we’ll still respect your decision. It’s your home and your money.

We approach those conversations the same way we’d want someone to approach a repair at one of our mother’s or grandmother’s houses.

Take care of the person first.

If you’re having problems with your heating and cooling system and aren’t sure whether another repair makes sense, contact Crabbe Service Company. We’ll troubleshoot the problem, explain what we find, and help you understand your options before you decide what comes next.
