Gas Furnace Replacement and Installation Cost in Denver

According to the U.S. Energy Information Administration, 75% of Colorado homes are heated with natural gas, making Colorado the fourth highest state to rely on gas heating. If you are in the Denver area and need a new gas furnace, here is what you can expect to pay, from the cost of the furnace to the cost of installation.


Average Cost of a New Furnace in Denver

In Denver, the average furnace replacement cost–including the cost of the unit and installation–is around $4,000. The price of a new furnace varies by city and state, but the biggest factors that affect the cost are the type, brand, output, and efficiency (see below) of the furnace. For a high-efficiency gas furnace in a larger home, a new gas furnace can run you $10,000, whereas an average-efficiency gas furnace in a small home can cost less than $3,000 (always be weary of unusually low prices).

Most HVAC contractors charge similar rates for furnace installation services, but it is always a good idea to get several quotes before you get a new unit. Many contractors will give you a free quote over the phone if you supply them with your home’s square footage, existing furnace infrastructure and efficiency wants/needs.


Gas Furnace Output: What Do You Need?

You need a furnace with the appropriate heat output–measured in British Thermal Units (BTUs)–for your square footage and climate. The more BTUs, the more heat your furnace can generate. Larger multi-level homes in cold climates need more BTUs than smaller ranch-style homes located in warm climates.

You can roughly calculate the load for your furnace based on your home’s total square footage of finished, heated space and the region or climate your house is located in. For Denver, you will need 45 to 50 BTUs per square foot. That means a 2,000 square foot home in Denver will need a furnace capable of 90,000 BTUs.


Energy Efficient Furnaces: How Much More Do They Cost?

The second metric to pay attention to is the furnace’s annual fuel utilization efficiency (AFUE).  A standard efficiency furnace has an AFUE rating of 80%, meaning 20% of the energy produced by natural gas is expelled as exhaust. A highly efficient unit has an AFUE rating of 90% or more.

A high efficiency furnace costs 50% to 100% more than the standard model. Depending on the location of your furnace, insulation of your home and your budget, an HVAC professional will recommend a unit with the appropriate AFUE.

Furnace vs Heat Pump in Colorado

Until recently, heat pumps were not a viable option for homes in colder climates, even places like Denver with mild winters. Now heat pumps can be used anywhere in the country, so the question is, do you choose a furnace or a heat pump?

Unfortunately, there is not a clear answer as to which system is better. Every home is different and the pros and cons of each system could sway your decision. Below are the most important factors to consider when choosing between a furnace and a heat pump for your Colorado home. We highly recommend speaking to an HVAC professional like Grand Home Services for a personal recommendation!


Gas vs. Electric

If your home does not have a gas line, then you cannot get a furnace. Furnaces run on natural gas and heat pumps run on electricity. It is very uncommon to have a home in Colorado without a gas line, so chances are you can still choose between both systems. If you have both gas and electricity, you have the opportunity to have a dual fuel system.


Dual Fuel System

If your home has access to both electricity and natural gas, you might want to consider a dual fuel system. Heat pumps are most efficient above freezing and can both heat and cool your home, and gas furnaces are much more efficient below freezing. Keeping both units running in their ideal temperature range allows you to keep the lowest possible operation cost during the winter.

A dual fuel system is best for those who do not have an air conditioner and already have a functioning gas furnace. If you do not have a heat pump or a furnace, a dual fuel system is not recommended.


No Air Conditioner

If you do not have an air conditioner, a heat pump will kill two birds with one stone as it can both heat and cool your home. If you do have an air conditioner, it is likely more cost effective for you to get a furnace.



The initial cost of a heat pump is typically more than a furnace, but keep in mind the unit runs year-round for heating and cooling. Because the unit runs year-round, it tends to have a shorter lifespan at about 10-15 years. Furnaces average a lifespan of 15-20 years. With regular maintenance and cleaning, it is not hard to have a heat pump for 15 years.

The operating cost for a heat pump tends to be more expensive when not coupled with a furnace as a dual fuel system. It’s not uncommon to have below freezing nights here in Colorado, and between the low cost of natural gas and efficiency of furnaces running below freezing, furnaces are typically the best choice for single unit heating.

As mentioned above, if you do not have an air conditioner and you have a functioning furnace, getting a heat pump would be the most cost-efficient in terms of operating costs. The heat pump would run on electricity in the summer just like an air conditioner and the furnace would run below freezing temperatures.

Get Your Furnace Ready for Winter

It’s not uncommon to simply turn on your furnace for the first time in months and do nothing to get it ready for the Winter season, but is that recommended? Yes, your furnace will still function, but with a few simple tasks you can keep your monthly heating bill low, prevent a breakdown and even prolong the life of the unit.

Here are 4 simple ways to get your furnace ready for winter. If you have any questions or concerns about your furnace, always consult an HVAC technician!

1. Change the filter

At an absolute minimum, your furnace filter needs to be changed before the winter season. Changing your furnace filter before the season could save you up to 15% on your energy bill. These filters are very inexpensive and could be saving you hundreds of dollars per season. In addition, changing your filters on a regular basis prolongs the lifespan of your system prevents breakdowns, and keeps your furnace and vents clean.

2. Get a tune-up

Getting a professional tune-up is the most efficient way to get your furnace ready for the winter season. The technician will make sure the unit is clean, check for any necessary repairs, lubricate the blower motor, and get your unit running at its peak performance to save you money on your monthly bill. Every other tip on this list is taken care of during a standard furnace tune-up.
If the furnace is more than 15 years old, we highly recommend having an HVAC technician take a look at the unit before you run it for a full season. The older your furnace gets, the more repairs and cleaning it will need to keep up. A technician can clean the system and take care of any repairs to prevent an even more expensive repair or complete breakdown.

3. Test your thermostat

If you live in a city like Aurora, Colorado, chances are you have already switched between your air conditioner and furnace a few times before Winter hits. When you turn on your furnace for the first time in several months, make sure the flame ignites and is burning the gas being pumped into the unit. If there is no flame but the furnace is on, turn off your furnace immediately and call an HVAC technician.

4. Clean around and inside the unit

Make sure there is nothing being stored around the furnace and the area is free of dust and debris. Furnaces get very hot and having anything within 30 inches is a fire hazard.

Cleaning the inside of the unit is much more complicated, so if you’ve never done it before, we recommend talking to a professional. Keeping things like the blower motor, ignitor and sensor clean help your furnace run efficiently. If you have several pets or someone in your home has a compromised immune system, keeping the inside of the furnace clean is even more important.

8 Warning Signs Your Furnace Needs Repair

When the weather gets cold, you rely on your furnace to keep your home comfortable and to prevent seasonal issues like bursting pipes. It is very common for your furnace to need repair when it is working hard for half the year, and even more common if your furnace is old or hasn’t been properly maintained.

To prevent more issues and extend the life of your furnace, it’s important to know what warning signs to look for. Here are 8 common warning signs your furnace needs repair and what they mean.


1. Your furnace is old

If your furnace is older than the average life expectancy of furnaces in homes today—between 16 and 20 years—your furnace likely needs attention. It’s not a bad idea to start shopping for a replacement just in case of an emergency, but it’s important you get an older furnace inspected and cleaned to prolong its life. If you are in the Denver Metro Area, we can help you with this.

2. Water is pooling around the furnace

If water is pooling around your furnace, it’s important to figure out why rather quickly to keep your house warm. Pooling water is usually caused by a clogged condensate drain line. This drain line removes water that is released when the evaporator in the unit converts refrigerant from a liquid to a gas. Fixing the problem is not as simple as just unclogging the drain line, so it’s best to work with a professional who has HVAC and plumbing expertise.

3. You smell gas

If you smell gas, turn off your furnace immediately. Then, look for a gas supply valve on the gas pipe near the furnace and close the valve. Make sure to call a local HVAC contractor as soon as possible to get the gas leak fixed.

4. It’s making persistent and strange noises

No furnace is silent, but loud and persistent noises can indicate a serious problem. Pay attention to the sounds you hear and, if possible, describe them to your HVAC contractor. Squealing and whistling noises may come from belt or fan issues while banging or groaning can result from broken and loose internal components. All these noises are signs that your furnace needs to be repaired.

5. Air blows weakly

From a minor problem with fans to a major problem with belts and motors, weak air flow can be caused by several things and can cause other problems if not fixed. Because the cause can be difficult to identify, it’s important to call a professional.

6. The thermostat is not working

If you have to turn your thermostat higher and higher to get heat, it’s definitely a sign your furnace needs repair. This malfunction is likely caused by an electrical issue like blown fuses, loose wiring, or tripped circuit breakers. Because it is likely an electrical issue, it can be dangerous to fix if you haven’t had any formal training. Call a trained HVAC professional you trust.

7. Your bill rises

As furnaces age, it is very common for them to lose their efficiency, especially if they have not been consistently maintained. As a result, your furnace will have to work harder and longer to provide the same amount of heat causing your gas & electric bills to go up. If you get your furnace repaired or replaced, you will likely save a lot of money in the long run.

8. The pilot light is discolored

A healthy pilot light usually appears blue. A pilot light of a different color, especially yellow, can indicate a ventilation problem like the carbon monoxide isn’t dissipating as it should. This is not only a health hazard for you and your family, but it can make your unit more combustible if not addressed.
