What Are the Best Heating and Cooling Options for a Sunroom?

Best Heating and Cooling Options for Sunrooms

No matter the weather, a sunroom is the perfect spot in your house to enjoy the outdoors while protecting you from the elements. But keeping your sunroom at the right temperature can be a challenge.

Due to their large, porous windows, sunrooms absorb the sun’s heat faster than other rooms in your home. Depending on the direction your room faces and the time of year, this can be a benefit.

But if the sun is pouring into your sunroom in the middle of summer or facing away from the sun during the cold winter months, it could cause uncomfortable heat or chill.

Whether you use your sunroom as a playroom, a morning breakfast spot, a workout area, or something in between, it’s important that your space is pleasant and inviting. Here, we’ll provide you with the best options for heating and cooling your sunroom, so you can reach optimal comfort levels.

Ductless mini-split system

Consisting of a wall-mounted indoor unit and an outdoor air compressor, a ductless or mini-split system is a flexible method of heating or cooling specific rooms.

With better energy efficiency than typical HVAC equipment, a ductless system can save you money in the long term, even with upfront installation costs. It’s also smaller and easier to install than a standard HVAC system.

Expanded HVAC vents

By expanding your home’s HVAC vents, you can keep your sunroom at a consistent temperature with the rest of your house. It will allow you to both heat and cool your sunroom using your existing thermostat and HVAC equipment.

Although it is an investment to install, it can be much more effective than other methods at keeping your sunroom comfortable. Plus, you’ll be able to add your sunroom to any smart automation technology you currently utilize.

Window AC unit

A window AC unit is a simple but effective option for cooling your sunroom and eliminating excessive humidity.

Because it is separate from your existing HVAC system, it is easy to install. But it also means you must manually turn the unit on and off every time you want to use it. This can cause a slight delay in cooling.

Space heater

Like a window AC unit, a space heater is an efficient way to heat your sunroom without undergoing an intensive, costly system installation.

Space heaters are convenient and portable, with no installation required. But like a window unit, a space heater must be manually operated, so it can take some time for your sunroom to heat up when in use.

PTAC (Packaged Terminal Air Conditioner)

A packaged terminal air conditioner, or PTAC, is a self-contained system that is installed through a wall. Typically used in hotel rooms or offices, they can both heat and cool your sunroom quickly and conveniently.

Quieter than typical AC units and easy to operate with digital controls, a PTAC is a great option for a peaceful, relaxing sunroom.

Overhead fan

Although an overhead fan doesn’t add cool air like an AC unit, it may be enough to cool your sunroom depending on its location and size. Additional portable fans can be added to improve circulation and comfort levels.


Installing a full-blown fireplace is a time-consuming, expensive undertaking. Luckily, there are plenty of low-maintenance electric options on the market to warm up your sunroom.

Whether you choose a freestanding, wall-mounted, or corner option, an electric fireplace can heat your sunroom to a comfortable temperature during the colder months while adding a cozy, aesthetically pleasing touch.

Window treatments

Sunrooms are known for their large, open windows that allow the sun to light and heat the space. But adding window treatments like shades, curtains, blinds, or drapes gives you more control over how much sun and heat is let into the room. These treatments can make a significant difference in your sunroom’s climate.
