So, you’re thinking about upgrading your Oregon heating and cooling system. Have you ever heard of dual fuel? 

Dual fuel systems pair a heat pump with a furnace or boiler. That way, your home will always be at the perfect temperature without sacrificing efficiency. It’s a way to combine the best of both worlds to keep your home comfortable year-round. 

L & J Heating & Cooling is happy to lay all the options on the table so you can make the best decision for your Oregon City home. Here’s what you should know about dual fuel systems: 

They Help You Save Money

Dual fuel systems take the burden off your furnace or boiler. Heat pumps can both heat and cool your home. During warm weather, they work like air conditioners, extracting heat and humidity from the air. When it begins to cool down, they reverse the process, concentrating and redistributing heat to warm your home. 

Heat pumps are up to 50 percent more efficient than a furnace or baseboard heater, according to the US Department of Energy (DOE). But they have their limitations when it comes to super cold weather.

Air-source heat pumps struggle in temperatures 32 degrees Fahrenheit or below. When the temperature dips below freezing, your dual fuel system switches over to the furnace. On those milder temperature days in fall and early spring, you’ll be able to heat your home more efficiently using the heat pump instead of the furnace. 

Advantages of a Dual Fuel System

Here are some of the best parts about switching to a dual fuel system:

They are much more efficient. Because your furnace or boiler only gets used when you absolutely need it, you’ll be using burning much less gas. Your furnace will also last way longer since it won’t be overworked. 

You’ll save money in the long run. Every cold day your heat pump is running in place of your gas heater, you’ll pocket the difference. Plus, some high-efficiency heat pump systems are eligible for tax credits. Be sure to check for these discounts when you’re searching for a model.

You’ll enjoy a quick payback period. You spend more upfront getting this system in place—but the return on investment is worth it.
