🔥 Is It Worth Fixing Your Pool Heater - or Replacing It?

Feb 21

If your pool heater isn’t working properly, you’re probably asking the big question:

Should I repair it… or is it time to replace it?

At Patriot Pool Service, we help homeowners in Allen, Anna, Fairview, McKinney, Melissa, Frisco, Prosper, and Lucas make this decision every single season. And the truth is - it depends on a few key factors.

Let’s break it down 👇

🔍 First: How Old Is Your Pool Heater?

Most gas pool heaters in Texas last:

7-10 years with proper maintenance
Sometimes less if chemical levels weren’t balanced
Sometimes longer if well maintained

If your heater is:

Under 5 years old → Repair usually makes sense 👍
7–10+ years old → Replacement might be smarter long-term

Older heaters often become inefficient and start needing frequent repairs - and those costs add up fast.

🛠 When Repairing Your Pool Heater Makes Sense

A repair is usually worth it if:

✔️ The issue is minor (blower motor, igniter, sensor)
✔️ The heat exchanger isn’t damaged
✔️ The cabinet isn’t severely rusted
✔️ The unit is still under warranty

We often replace parts like:

Heater blowers
Pressure switches
Control boards
Sensors

These repairs are significantly less expensive than full replacement and can extend the life of your unit.

🚩 Signs It May Be Time to Replace

Here’s when we usually recommend replacement for homeowners in McKinney, Allen, Prosper, and surrounding areas:

1️⃣ Rusted or Cracked Heat Exchanger

This is the heart of the heater. When it fails, repairs can be costly - sometimes half the price of a new unit.

2️⃣ Severe Rust or Corrosion

Texas weather + imbalanced chemicals = corrosion.
If the cabinet and internal components are deteriorating, replacement is often the safer option.

3️⃣ Repeated Repairs

If you’ve repaired your heater multiple times in the last 1–2 years, you’re likely throwing money at a failing system.

4️⃣ Rising Gas Bills

Older heaters are far less energy-efficient. A new high-efficiency model can lower monthly operating costs.

💰 The Cost Comparison: Repair vs Replace

While every situation is different, here’s a general rule we use:

👉 If the repair costs more than 40–50% of the price of a new heater, replacement is usually the smarter investment.

Why?

Because you don’t want to spend $1,200 - $1,800 repairing a unit that may fail again next season.

🌡 Texas Climate Matters

In cities like Frisco, Melissa, Lucas, Anna, and Fairview, pool heaters work hard during:

Early spring
Late fall
Unexpected cold snaps
Spa use year-round

The more your heater runs, the more wear and tear it experiences. That’s why proper maintenance and chemical balance are critical.

🧪 Don’t Ignore Chemical Damage

One of the most common causes of heater failure we see in Prosper and McKinney?

⚠️ Low pH and imbalanced chemicals.

Acidic water can:

Destroy heat exchangers
Corrode internal components
Void manufacturer warranties

Routine maintenance protects your investment.

🔄 When Replacement Is the Better Move

Replacing your heater may be the right choice if:

✔️ It’s 8–10+ years old
✔️ Major internal components have failed
✔️ It’s inefficient
✔️ You want better energy savings
✔️ You’re upgrading your equipment pad

Newer models:

Heat faster 🔥
Run more efficiently 💨
Are quieter 🤫
Come with warranty protection
