Furnace Replacement and Installation in Denver

Furnaces normally last an average of 18 to 20 years, depending on whether it has been consistently and professionally maintained. However, just because you have an older furnace model doesn’t necessarily mean it needs to be replaced, as age isn’t the only factor that may signal a failing furnace.

Below are our average prices for a standard installation of the listed furnaces. Some homes may require additional work and cost more than others when extra material or code upgrades are required, permits are billed seperately. Please call us for an over the phone quote or free in home estimate to confirm your total price. We offer Lennox and other major manufacturer products.

AFUE represents the furnace gas efficiency 

1 stage furnace burner operates on high fire only.

2 stage furnace burner operates on low or high fire depending on demand, provides better comfort and efficiency by using only what is needed.

Standard blower motor uses a typical 120v electrical circuit to operate, this is a standard efficiency motor

Here are six factors to consider in addition to the age of your furnace when deciding if it’s time for a furnace replacement:

1. Cost of maintenance. The cost of maintaining your heating system will give you a good indication of whether it is cost effective to keep using your current model or opt for a newer one. Although replacing a furnace can be pricey, an older heating system might not have the technology to keep your heating bills as low as possible and could be costing you more than necessary.

2. Cost of repair. If your aging furnace requires repair and the cost is significant, it makes more sense to put that money toward a new furnace. It would be wiser to invest those dollars in a newer, more energy efficient system than spending them on a repair for an older system whose life span may be questionable. If you have a furnace that has required a lot of repairs in the recent past, that’s even more reason to consider a replacement.

3. Changes in your home. Have you remodeled or added on to your existing square footage since your furnace was first installed? Your current unit may not be sufficient to effectively heat your revamped floor plan.

4. Comfort level. As furnaces age, they must work harder to keep your home warm in the winter, sometimes running constantly, which can not only cause quite a hike in your heating bill but could affect your comfort level as well. A newer furnace can keep your home comfortable without working as hard as an older unit. This will extend the life of the furnace and save you money in the long run.

5. Current AFUE ratings. Is your furnace up to code? Newer furnaces are required to have an AFUE rating of at least 78 percent. If your furnace has an AFUE rating lower than that, it is not only an indication of an older system, but it does not meet current industry standards, and your heating bills are undoubtedly higher than if you had a high-efficiency system.

6. Chronic noises, smells, or rust. If you notice your furnace beginning to make strange noises, produce odd smells or show signs of rust, it’s time to replace it. Any of these conditions could be signs of an impending furnace failure.
