Ventless gas fireplace — Denver, CO

Last updated: September 24, 2026

What affects the price

The final price for a new gas fireplace depends on a few moving parts. First, you have to consider whether you are installing a unit into an existing chimney or creating a new opening in a wall, which adds labor. The type of venting required and the current proximity of your gas lines also play a big role in the complexity of the install. Aesthetic choices, like premium stone surrounds or remote-controlled flame features, will adjust the total as well.

About this service

A ventless fireplace is designed to burn clean enough that it does not require an external chimney or flue. These units are great for supplemental heat but require strict adherence to safety and maintenance guidelines. You need this service if your unit is producing an odor, if the flame color is off, or if you require an annual sensor check. We prioritize safety by ensuring your oxygen depletion sensor is functioning perfectly, which is critical for the proper operation of these systems.

Many people think about fireplaces only in the cold, but summer is actually a great time to schedule an installation. Since demand is lower, you can often get your project finished without the long wait times seen during the peak winter months, making sure you are ready before the first frost arrives.
