Depending on your home’s age and size, you may have aging heating or A/C systems separate from each other. Even if one of them still works, it’s still an excellent time to switch over to a new, more modern system that’s easy to install and maintain.

Ductless all-in-one heating and cooling units are an easy way to manage your home’s temperature year-round. These units allow you to customize the temperature of your house’s different zones without wasting energy heating or cooling areas that aren’t in use.

They’re also easier and faster to install than many other types of heating and cooling units. Even if your home is older and you don’t want to cut into the walls, a licensed HVAC professional can install the new system quickly. Here’s how to choose and switch to all-in-one heating and cooling units.

Control Your Home’s Temperature with an Efficient Ductless Mini-Split System

Estimate Your Needs

Your heating and cooling needs will largely depend on your home’s overall size and age, as well as how extreme outside temperatures can get. Poor insulation in walls and windows is a huge contributing factor to heating and cooling needs, so your units may need more British Thermal Units (BTUs) than average for a home your size if your home has large windows or inadequate insulation. 

However, your floor plan also makes a difference in your needs. If you have a large open floor plan on the first floor, you might need one large indoor unit in the living room and only one small separate one for the master bedroom. 

Use the square footage listed on each indoor and outdoor unit’s product specifications to estimate which unit you need for each room or floor. Since interior hallways don’t need a heating or cooling source, focus on the rooms people spend time in. Bathrooms also might not need their own unit, especially if they are connected to a bedroom.

Since ducted mini splits are up to 30% more efficient than ducted systems, rooms or areas that you struggled to heat or cool in the past might not have the same problem anymore. However, you’ll want to consider placing an indoor unit as close to that problem area as possible, especially if it has a lot of windows that can contribute to heat or cooling loss.

Select the New Setup

There are two main types of all-in-one ductless systems. Single-zone systems are designed to keep an entire area at the same temperature, while multi-zone systems can use different indoor units to manage areas with separate temperature settings.

Since you can connect multiple indoor handler units to one outdoor one, you can usually use one outdoor unit per floor or zone. However, to minimize piping running across the house, you may need to have outdoor units installed on opposite ends of the house.

Look closely at the features and accessories listed on each unit or system. Almost all modern systems have remote controls with small screens, but Wi-Fi-enabled systems with apps are less common. If you’re looking for the ultimate in modern convenience, get a Wi-Fi-compatible system for better scheduling and the ability to control your heat when you’re not even home.

ComfortUp has a variety of trusted brands to choose from, including Gree mini splits. Although manufacturers vary in their features and warranty terms, they are all established and reputable companies with extensive manufacturing HVAC equipment experience.

Remove and Replace

While it is not completely necessary to remove the old ductwork when installing a new mini split HVAC system, air vents and degraded, cracked ducts can lead to heating and cooling inefficiencies, overworking the motor on your new condenser unit. Duct removal is a complex process as much of the ductwork is in hard-to-reach spaces. Contact a professional duct removal or demolition company to dispose of your old ducts. 

Fortunately, you can remove old radiators, window units, and other bulky HVAC equipment yourself in preparation for installing your mini split system. However, avoid dumping used HVAC equipment in a landfill. Hire a recycling company to dispose of old furnaces or AC window units in an environmentally friendly way.

Even if extensive removal is required, mini split installation is usually faster than other types of HVAC units. A licensed HVAC technician can complete the installation of a basic single-zone system in a single day, with minimal disruption.
