A new furnace is a long-term commitment. Most systems last 15 to 20 years, which means a poor choice today follows you through many Denver winters. The wrong size unit will either struggle to heat your space or cycle on and off constantly, wearing itself out faster and driving up your energy bills either way.

Getting it right comes down to understanding your home’s specific heating needs and our Colorado climate before anyone picks up a tool.

  • An undersized furnace runs constantly and still can’t keep up on the coldest Denver days
  • An oversized furnace short-cycles, reducing efficiency, comfort, and adding wear to the system
  • Poor installation can void a manufacturer’s warranty, reduce efficiency, and create safety issues down the road
  • Choosing the wrong efficiency rating for our Denver climate can cost you more over time than the upfront savings suggest

We treat furnace installation as two separate jobs: helping you choose the right system for your Denver home, and then installing it properly. Both matter.

Sizing your home correctly. Before we recommend anything, we assess your home’s square footage, insulation, layout, and existing ductwork. That assessment determines what size and efficiency rating actually makes sense for your comfort and Denver’s winter temperatures.

Walking you through your options. We’ll present a few furnaces at different price points and explain the tradeoffs in plain terms. Higher efficiency costs more upfront and saves more over time. We’ll help you find the right balance for your budget and how long you plan to stay in the home.

Professional installation. We handle everything from removing any existing equipment to connecting the new unit, testing airflow, checking gas and venting, and verifying that the system is operating safely and efficiently before we leave.

Cleanup and walkthrough. When the job is done, we walk you through how the system operates, how to use the thermostat, and what to expect in the first few weeks. We leave the space the way we found it.

Furnace sizing is based on your home’s square footage, ceiling height, insulation quality, ductwork, and our Denver-area climate. It’s not something to estimate — an undersized or oversized unit creates problems that persist for the life of the system. We do a proper assessment before recommending anything.

Most new furnace installations fall in the $2,500 to $5,500 range depending on the unit and the complexity of the job. Homes that need new ductwork, venting changes, or significant modifications will be on the higher end. We provide a clear written estimate before any work begins.

Most installations are completed in one day. If your project involves ductwork modifications, gas line work, or other prep, we’ll give you a realistic timeline upfront so you know what to expect.

An 80% efficiency furnace converts 80 cents of every dollar of fuel into heat. A 95% unit converts 95 cents. The higher efficiency unit costs more upfront but saves money on your heating bill each month. In colder places like the Denver metro, the payback period is typically shorter, making the higher efficiency option worth considering.

Yes. Denver Comfort and Climate pulls the necessary permits and schedules any required inspections as part of the installation process. You don’t need to manage that separately or deal with the city yourself.
