Why It Matters
Our winter insulation service adds protection to exposed pipes and vulnerable areas, helping reduce the risk of freezing, costly damage, and unexpected hot water interruptions during colder weather.
Many outdoor units include built-in freeze protection for the heater itself, but it depends on electrical power and does not cover every exposed pipe. Insulation adds a second layer of protection for the plumbing.

Common Questions
When should I book winter insulation?
In the fall, before the first hard freeze. Insulation is quick to install and protects your system all season.
My heater has freeze protection. Do I still need insulation?
Built-in freeze protection covers the unit itself and relies on power. Exposed pipes and fittings outside the cabinet can still freeze, so insulation adds protection.
How long does it take?
About 25 minutes for most outdoor units.
