A Lightning Strike Took Out This Springfield, MO HVAC System

Storms in southwest Missouri do not always announce what they took with them. A homeowner in Springfield, MO found that out after a lightning strike left several different components of her HVAC system damaged. It was not one bad part. It was a handful of them, and finding all of them took repeated testing rather than a single guess.

Here is the short version. A surge from a nearby strike can travel through the power line into your equipment and take out multiple electronic components at once. Replacing one and hoping is how you end up with a second no-cool call a week later.

Why lightning damage is rarely just one part

Today’s heating and cooling equipment runs on circuit boards. There is a control board in the air handler, one in the outdoor unit on many systems, a thermostat with its own processor, and low voltage wiring connecting all of it. A voltage spike travels that entire path. Some components fail outright and are obvious. Others get weakened and fail a few days later, or work intermittently, which is the frustrating kind.

That is why thorough testing matters more than speed here. Every board, contactor, capacitor, and sensor has to be checked, not just the one that failed loudest.

What happened on this repair

The team tested and retested until the full extent of the damage was clear, then Matt walked the homeowner through what was still outstanding and what would happen next. Parts for storm damage often have to be ordered, and this was the middle of a Missouri summer, so Paschal loaned her two window units to keep the house livable in the meantime.

“My issue was caused by a lightening strike with several different components damaged. Paschal tested over and over until the damaged was assessed completely. Matt was very knowledgeable and informative of the remaining issues. Paschal even loaned me 2 window units to get me through the heat while waiting for parts.”

How to keep the next storm from doing this

You cannot stop lightning, but you can stop most of what it sends down the line. A whole-home surge protector installs at your electrical panel and clamps voltage spikes before they reach your circuits. It protects your HVAC equipment along with everything else in the house that has a circuit board, which today is nearly everything. It is a small line item next to the cost of replacing a control board, and a very small one next to replacing a system. Our electrical services page covers panel and protection work.

A few other things help. Know where your outdoor disconnect is, so you can cut power to the unit if a storm is coming through and the system is already acting strange. And after any close strike, pay attention to whether the system behaves differently, even slightly, rather than waiting for it to quit.

Frequently asked questions

Can lightning damage an HVAC system without hitting the house?

Yes. A strike anywhere on the power grid nearby can send a voltage surge down the line and into your equipment. Modern systems are full of control boards and sensors, and those fail long before anything mechanical does.

What parts of an HVAC system does a surge usually damage?

Control boards, contactors, capacitors, thermostats, and communicating equipment are the usual casualties. A surge often takes out several at once, which is why a single part replacement sometimes does not solve the problem.

Will homeowners insurance cover lightning damage to an air conditioner?

Lightning damage is typically a covered peril on standard homeowners policies, though deductibles and depreciation apply. Your technician can document what failed and why, which helps when you file. Check with your carrier for what your specific policy covers.

How do I protect my HVAC system from the next storm?

Whole-home surge protection at the electrical panel is the most effective step, and it protects everything else in the house at the same time. Whole-home surge protection starts at $699 with Paschal.
