Should You Replace Your Oil or Gas Boiler with a Heat Pump?

Learn key differences between boilers and mini splits.

Kearney are your local pros!


Is your gas or oil boiler on its way out? Mitsubishi Electric Heating & Air Conditioning systems are quickly becoming a new favorite source of heat and air conditioning among North Shore, MA and Seacoast, NH homeowners. These powerful electric systems are an excellent choice!

Let’s explore some of the differences between these home heating systems from the pros at Kearney HVAC! 

What are the Differences Between Boilers and Mini Splits?

A new heating system is an investment, so it’s important to do all your research in advance to know what the best choice will be to keep you and your loved ones safe and comfortable.


The lifespan of both Mitsubishi Electric heat pumps and boilers is around 10 – 20 years, making both systems reliable, long-term options. 


Ductless mini splits are exactly what they sound like — ductless! Heat pump installation is quick and easy, taking only 1-2 days to complete depending on the number of units you’re having installed.

Units from Mitsubishi Electric Heating & Air Conditioning can be installed in any exterior wall, making them great options for whole-home heating and cooling, as well as a great supplement for tough to condition areas like garages and sunrooms. 


Boilers carry an innate risk of carbon monoxide leak by nature of their fuel source design. This can be caused by fuel not being fully burned and a malfunction of the built-in ventilation system. Heat pumps run on electricity, meaning there is no risk of carbon monoxide leak in your home from your heating and cooling unit.


All-electric technology has made massive strides over the past decade, which makes Mitsubishi Electric mini splits more efficient than ever. Mini split efficiency also helps the average homeowner save on their monthly utility costs!

According to The Wall Street Journal, heat pumps have never been a more viable alternative to traditional heating systems that run on fuel. And, Mitsubishi Electric Heating & Air Conditioning systems are some of the best systems for very cold weather!

Versatility + Maintenance

Mitsubishi Electric Heating & Air Conditioning systems come out on top here: mini split heat pumps provide both heating and cooling from a single unit. This minimizes your costs because instead of having to repair and maintain a boiler and a cooling system, you only need to maintain your mini split. 

This is an added bonus for New Englanders! Not all homeowners feel compelled to invest in an AC system since the hot season is shorter than other parts of the country, but with a mini split already installed for heating, you can enjoy the benefits of cooling as well. 

Impact on the Environment

Boilers use either oil or gas to warm your home, making them tough on the environment by their nature. Mini splits are electric, so if you install one, it can help you reduce your carbon footprint while still staying safe and comfortable year-round.
