How to Keep Your Sunroom Comfortable Year-Round
Date: 06-15-2025
Thinking about turning that sunroom into a space you'll actually use throughout the year? Whether you're sipping coffee in the morning light or relaxing with a book in the evening, making the space livable year-round means figuring out how to keep it warm in winter and cool in summer.
First Things First: What's the Plan for the Room?
Before diving into heating and cooling options, it's worth considering how you plan to use the space. Is it going to be a seasonal retreat, or are you hoping it becomes a year-round extension of your home? That decision affects everything—from the type of sunroom you build to the materials you'll want to use.
Aluminum framing is common in sunroom construction, but it doesn't offer much insulation. If you're thinking of long-term comfort, especially during extreme temperatures, vinyl may be a better option thanks to its improved insulation properties.
Heating Your Sunroom Without Overcomplicating Things
One of the simplest ways to warm up a sunroom in cooler months is with a space heater. They're affordable and easy to use—just remember to never leave them unattended. Another easy fix? Lay down a thick rug or carpet. It's a small change that helps trap heat and keeps the floors from feeling like ice.
If you're looking for a more permanent solution, and your HVAC system has the capacity, you might consider extending your existing ductwork into the sunroom. You'll want a professional to take a look like Mid-State Heating and Air LLC to make sure your current unit can handle the extra demand. Depending on the design of the room, vents can go in the floor or even in the wall if there's a lot of glass overhead.
And if ductwork isn't practical, a ductless mini-split system might be the answer. These systems offer heating and cooling without the need for existing ducts and can be controlled easily with a remote—perfect for sunrooms.
Cooling That Glass Box When Summer Hits
All that sunlight is great—until July rolls around. Extending your HVAC system can help cool your sunroom just like it does the rest of your house, but good insulation and smart design choices go a long way too.
Start with windows. If you're still planning the build, choose energy-efficient or insulated windows to help hold in the cool air. Tinted glass can block out a good bit of that heat, although it may change the way the room feels visually. If you already have your windows, consider adding blinds or light-blocking shades. They not only cut down on heat but also give you more control over the lighting.
One System, Two Seasons
For many homeowners, a ductless heat pump strikes the perfect balance. These systems provide both heating and cooling without requiring extensive renovations. They're especially useful in spaces like sunrooms, bonus rooms, or converted garages—anywhere traditional ductwork is hard to run. Better yet, they can often be expanded to handle multiple rooms if needed.
