"I can’t say enough good things about Cooper…"

I can’t say enough good things about Cooper heating and cooling! They are a superior company - and I don’t usually write reviews because I am typically not happy with companies. Cooper changed that for me and deserves all the positive praise possible!

Boiler installation cost factors:

Boiler size

Boilers come in different sizes or power outputs. To measure a boiler's size, you'll want to check its BTU output, which is the amount of heat it provides in an hour. Higher BTU boilers are used to heat larger homes.

To make sure you're getting a boiler size that perfectly matches your home, we perform a heat loss calculation during your free estimate.

The condition of your radiators/baseboards

Boilers rely on a network of pipes that send heat to radiators/baseboards and warm your home.

Most of the time, a new boiler can use the existing pipes, but if those pipes are in poor condition, they may need to be replaced or repaired, which will increase the installation cost.

Pulling permits

Depending on where you live in Denver, your boiler installation may necessitate pulling one or more permits. Unfortunately, pulling permits can be costly and time-consuming, and homeowners should remember to add this to the overall boiler installation cost.

At Cooper, we handle all permit paperwork and filing, and we wrap that cost into the overall installation to save you time and money.

Looking for a more accurate estimate for your boiler installation?

Just call the Cooper Green Team. We'll send over an experienced Project Manager to perform a load calculation and then provide an honest estimate for your boiler installation.
