Are dual fuel systems right for your Portland, OR home?

A dual fuel system combines a gas furnace with an electric heat pump. It’s great for homeowners who want a reliable heat source during frigid temperatures while also gaining the benefits of a high-efficiency heat pump. Since heat pumps can heat and cool homes, work well in cold climates, and help homeowners reduce fossil fuel usage, many Oregon residents opt to install dual fuel systems.

Amidst all these benefits, you might wonder, why not just install a heat pump? Although heat pumps provide air conditioning for Portland homeowners—which is vital as summer temperatures continue to rise!—they cannot heat homes well once temperatures drop below 30 degrees Fahrenheit. In this case, a gas-powered furnace is necessary to compensate.

To help you decide what’s best for your year-round heating and cooling needs, comfort, and budget, let’s review the pros and cons of installing a dual fuel system:

Advantages of Installing a Dual Fuel System

Dual fuel systems can be more eco friendly

If homeowners express the desire to convert to a dual fuel system during one of our comfort consultations in Oregon, we always ask them why they’re interested in making the change. Their answers help us address any misconceptions.

Something we commonly hear from customers is, “I just want to get away from fossil fuels.” Electric heat pumps help homeowners reduce their reliance on fossil fuels by at least 60%, which is the main advantage of a dual fuel system. According to PGE, about 40% of the electricity generated is from burning oil or coal. While electric heat pumps do not completely abandon fossil fuels, they still significantly reduce harmful emissions.

Reducing fossil fuel usage is significant enough to warrant federal rebate programs. The High-Efficiency Electric Home Rebate Act (HEEHRA) and Homeowner Managing Energy Savings (HOMES) Program help homeowners cover up to $8,000 of their electric heat pump installation costs. Both rebates are part of national efforts to slash domestic greenhouse gas emissions by 40% in the next decade.

Not to mention that a dual fuel system is an energy-efficient feature that can help your home sell for more and, sometimes, faster. According to Zillow’s research, 67% of buyers state that these features are very or extremely important to them when purchasing a home.

Essentially, there are few downsides to installing a dual fuel system for homeowners who want one as part of their eco-friendly lifestyle and beliefs. We’ll let the homeowner know if a heat pump installation is viable for their home or if they need home upgrades because some electrical issues or the equipment’s physical size can prevent proper installation.

Plus, we’ll let our customers know what their savings in the winter could be. For example, an electric heat pump dual fuel system can save an Oregon homeowner about $20 per month on average during the four coldest months of the year. However, saving significant amounts of money by switching to electric systems is a misconception and one we’ll cover in the disadvantages section.

Disadvantages of Installing a Dual Fuel System

Natural gas systems can cost more to operate

Due to natural gas costs becoming prohibitively expensive nationwide, many states are attempting to move away from using natural gas as the primary heat source. California is a prime example, although they still require residents to have a gas-powered back-up heat source for emergencies to alleviate the burden on electricity grids. Unsurprisingly, many homeowners answer our “Why are you interested in converting to a dual fuel system” question with “I heard I can save money by switching from natural gas to electricity.

While saving money is true to a degree, it’s not the full picture. There are monetary disadvantages to a dual fuel system’s installation and operation. Usually, Oregon homeowners can save around $100 per year with a heat pump. But, homeowners are also looking at an upfront purchase price of about $2,000 more for a heat pump installation.

Another factor to consider is system lifespan. Heat pumps last 14-15 years compared to a natural gas furnace’s 18-20 year lifespan. By switching to a dual fuel system, you could be paying approximately $2,000 more for equipment that will not last as long.

When faced with these practical concerns, many homeowners will abandon their intention to convert to a dual fuel solution out of an abundance of caution for their wallets.

Should You Install a Dual Fuel System?

Overall, we recommend installing a dual fuel system for your Oregon home if your primary reason is to reduce your natural gas consumption, as the system will deliver on the advantages of electrification. Having a gas furnace as a back-up heat source also keeps you toasty warm on the coldest of days since heat pumps cannot provide intense warmth.

Otherwise, you’re better off not installing a dual fuel system if you only want one to save money since the operational savings will not compensate for the upfront costs for long enough to make up for the installation price.
