How to Insulate Your Home for Better Heating Efficiency

Simple Steps to Stay Cozy and Save Money This Winter

When the temperatures drop, the last thing you want is for your heat—and your hard-earned money—to slip right out the door. Good insulation is one of the best ways to keep your home warm and energy bills under control. The good news is, you don’t always need to make a huge investment to see a difference. From no-cost habits to affordable upgrades, there are plenty of ways to improve your home’s insulation and heating efficiency.

4 No-cost Ways to Keep Heat In

Not everything requires tools or a major investment. A few simple changes can make your home feel warmer right away.

1. Close doors to unused rooms. By keeping heat concentrated where you need it, your system won’t need to work as hard.
2. Let the sun in. Open curtains and blinds during the day to naturally warm your rooms, and close them at night to hold in the heat.
3. Move furniture away from vents. Make sure warm air can circulate freely instead of getting trapped behind a couch or heavy drapes.
4. Stop drafts. Roll up towels and place them at the base of drafty doors. For a more polished look, you can find inexpensive but good-looking options at home stores.

4 Low-Cost Insulation Boosters

A small investment can go a long way when it comes to blocking drafts and keeping warm air inside.

1. Weatherstripping and caulking is an easy DIY project that doesn’t require much home-repair skills. Sealing gaps around windows and doors is one of the easiest and most affordable fixes you can make. Even small cracks can make a big difference in heat loss.
2. Plastic window film kits are another project almost anyone can tackle. These inexpensive kits add an extra layer of insulation to drafty windows and can be installed in an afternoon.
3. Thermal curtains are heavier drapes or insulated panels that keep cold air out and warmth in, especially on older windows. Depending on your skills, you may need a handyman to help hang them.
4. Outlet and switch plate foam inserts are a cheap and effective solution for small leaks. Hold your hand near outlets on exterior walls—you may be surprised at how much cold air is coming in.

1 Big Win for Comfort and Savings

Swezey offers free home-energy audits with a Building Performance Institute-certified auditor who will evaluate your whole home to show you simple upgrades and fixes you can make to help lower your energy costs even more. Ultimately, you could save thousands of dollars!

It’s a top-to-bottom evaluation of your home using state-of-the-art tools that can identify and measure heat loss and air flow in your home so you can correct the problems that lead to higher heating (and cooling!) costs, as well as uneven temperatures in your home.

Following the audit, we’ll walk you through the results and present the options to help you correct the problems. Depending on the results, your options can range from DIY projects to duct sealing and updating or adding insulation to attics and other areas. We’ll also show you how you can take advantage of rebates, tax credits and low financing rates to make upgrades even more affordable.

The Bottom Line

Insulation works best when paired with regular home heating system maintenance. A well-tuned furnace or boiler will run more efficiently, keeping you warmer for less. Together, these steps can make your home more comfortable while giving your wallet a break.

Winter doesn’t have to mean higher bills or chilly nights. By combining no-cost habits with low-cost upgrades, you can create a snug, energy-smart home that keeps the warmth where it belongs—inside. Contact us for more information today.
