Winter is just around the corner – time to think about how you can button up your house to make sure it’s comfortable without costing you a fortune in energy bills. The Daily Green has put together a great list of easy weekend projects to help you winterize your home.
- Dodge the Draft(s)
According to the U.S. Department of Energy, drafts can waste 5% to 30% of your energy use. Start simple and adopt that old Great Depression fixture — the draft snake, which you can easily make yourself. Just place a rolled bath towel under a drafty door, or make a more attractive DIY draft snake.
- Change Furnace Filters
Yes it’s easy to forget, but it’s important to replace or clean furnace filters once a month during the heating season. Dirty filters restrict airflow and increase energy demand. Here’s a worry-saving tip: mark a monthly check on your calendar.
Better, consider switching to a permanent filter, which will reduce waste and hassle. Did you know that disposable fiberglass filters trap a measly 10 to 40% of debris? Electostatic filters trap around 88%, and are much better at controlling the bacteria, mold, viruses and pollen that cause illness and irritation.
- Run Fans in Reverse
Most people think of fans only when they want to be cool, but many ceiling units come with a handy switch that reverses the direction of the blades. Counterclockwise rotation produces cooling breezes while switching to clockwise makes it warmer: air pooled near the ceiling is circulated back into the living space – cutting your heating costs as much as 10%!
- Turn Down Your Water Heater
While many conventional water heaters are set to 140 degrees F by installers, most households don’t need that much steam, and end up paying for it — in dollars and the occasional scalding burn. Lowering the temperature to 120 degrees F (or lower) would reduce your water heating costs by 6% to 10%.
- Give Your Heating System a Tune-Up
You probably already know that cars need periodic tune-ups in order to run their best. Well the same is true for heating equipment. Keeping your furnace clean, lubricated and properly adjusted will reduce energy use, saving up to 5% of heating costs.
If your entire furnace is in need of replacement, it will cost a lot more — but replacing an inefficient burner for a modern machine will save you every month through the heating season. Be sure to take advantage of federal tax credits for new furnaces, which can cover 30% of the cost, up to $1,500.
- Mind That Thermostat
It’s easy to forget to turn down the heat when you leave the building, but doing so is one of the surest ways to save money. Most households shell out 50 to 70% of their energy budgets on heating and cooling, so why pay for what no one uses?
For every degree you lower the thermostat during heating season, you’ll save between 1 and 3% of your heating bill. Make it easier with a programmable thermostat; they are widely available for as little as $50, and the average family will save $180 a year with one.
For even higher impact on your home’s comfort and energy bills, contact Recurve so we can provide expertise on projects such as:
- Air sealing – simple leaks can sap home energy efficiency by 5% to 30% a year, according to the U.S. Department of Energy.
- Insulation – it may not seem sexy, but insulation is one of the best ways to save energy and money at home.
- Duct sealing – studies show 10% to 30% of heated (or cooled) air in an average system escapes from ducts. Properly sealing ducts can save the average home up to $140 annually, according to the American Solar Energy Society.
- Upgrade to an efficient furnace – if your furnace is old, you could save a lot of money in the long run (and improve your home’s value) by upgrading to a new unit.

Fall is the perfect time to start prepping your house for winter. The U.S. Department of Energy suggests these 5 steps to ensure that your home stays comfortable this winter without costing you an arm and a leg:
- Look for rebates from your utility or state. Recurve has put together a handy resource for available incentives on our website.
- Get an energy audit. In order to know how to save energy, you have to first find out where you are losing energy – and money.
- Have your heating system serviced. Keep your system operating efficiently, and don’t forget to replace your furnace filter once a month or as needed.
- Find and seal your air leaks. This includes less obvious gaps such as recessed lights and unfinished spaces behind cupboards and closets.
- Check your insulation and add more as needed. Insulation is often the most cost-effective energy improvement you can make in your home.

Here’s a piece written by Matt Golden and Jess Chamberlain for Sunset Magazine on best practices for keeping your house cool, the environmentally friendly way.
To keep a house cool, it’s really about either:
- Keeping the sun out, or
- Keeping the air cool/conditioned
In a retrofit situation, you have to first assess what your possibilities are:
- Is there an attic we can insulate?
- Are there eaves that are blocking some of the summer sun?
- Is there an existing cooling system?
This really affects what the best approach to take is.
For an average house in a cooling climate with an attic, we’d recommend reducing the cooling load as much as possible and utilizing passive cooling:
1. Air sealing
2. Adequate attic insulation (min. R-38) to create a thermal barrier
3. Radiant barrier, if there are ducts in attic; on roof decking or in attic
4. Low-E glazing on windows
5. Whole-house fan
This route is very cost-effective from a long-term standpoint; i.e. you’re not paying to condition the air, you just pay for the equipment and installation.
The other option is to actively cool the house, in which case you’d invest in the fundamentals (such as air sealing and insulation), then install a high SEER-rated AC unit (min. 16-18 SEER rating) designed to ACCA’s manuals J, S, D & T. If air handling equipment is located in the attic we would recommend encapsulating the attic with air-impermeable spray foam and bringing the attic into the building envelope. This prevents hot attic air (150˚F+) from infiltrating the duct system.
Easy Cooling Tips:
- Keep your AC unit in the shade
- Keep the coils clean
- Install high efficiency lighting (it keeps house cooler)
- Turn plug loads off
- Stop the sun before it gets into your house – use external shading, overhangs, and deciduous trees
- Low-E coating on windows

Here are some easy and effective home energy fixes you can do around the house for $2 to $90:
- Light switch and outlet sealers: under $5
Two of the most frequently overlooked sources of air leakage in a home are light switches and outlets. Dodge those drafts by sealing up any switches and outlets where you can feel a draft on your hand.
- Hot water heater pipe insulation: $2 per foot
Use this cost-efficient fix as a quick way to reduce wasted energy on water heating. Insulating just the first 6 feet of pipe from your water heater will cost $12 and will save you over $5 a year on water heating while reducing CO2 emissions by more than 55 pounds. We typically recommend insulating the first 10 feet of pipe.
- Monitor your meter: $20
Purchase a Kill A Watt electricity monitor and plug in your appliances and electronics to find out which ones are the biggest energy culprits. Use this to inform your future upgrade decisions or see how much energy you can save with easy adjustments like turning down your refrigerator’s temperature.
- Smart powerstrips: $20-90
Cut back on phantom power by plugging electronics into smart powerstrips, such as the one by Wattstopper which turns devices on and off based on occupancy and uses a motion detector to manage energy use. Our recommended smart strip is Belkin’s Conserve.
- Faucet aerator: $2
These handy products are one of the least expensive ways to increase your water efficiency by mixing air into the water stream. When installed, each aerator will save 500-2,000 gallons of water a year.
- Chimney balloon damper: $35-50
The fireplace is a common area for heat loss in your home, as most dampers don’t work well and many older homes don’t have them. Inflatable balloon dampers fit in most chimneys to keep heated air in, and you can remove them whenever you want.

The gaps you can find around the windows and doors of the average American house add up to the equivalent of a hole in the wall that measures 10 inches by 10 inches.
Your house has more leaks than the CIA. There are cracks all over the place. Your doors and windows don’t quite meet their frames; there are tiny spaces where the walls almost join the floor; there are open areas around your electrical and plumbing outlets. And these little gaps eat energy. In fact, an amazing amount of heat in the winter – or cool air in the summer – escapes through them. But you have two simple weapons to fight with: caulking and weatherstripping.
Energy Facts
- Caulking and weatherstripping an electrically heated home can keep some 1,000 pounds of CO2 out of the air. So if 1,000 of these homes were weatherized, over a million pounds of CO2 would be saved.
- Believe it or not, stopping air infiltration can reduce your home’s heating and cooling bills by up to 40%.
- People are concerned that although weatherstripping may save energy, it will keep fresh air out of their homes. While it’s true that some ventilation is necessary, it’s really not much of a problem – a typical house may get twice as much fresh air as it needs. In other words, the air is probably flying out of your house as quickly as you’re heating or cooling it.
Caulking vs. Weatherstripping
- Cracks without any moving parts – like the places where a wall in your house meets the outside edge of a window frame, or two other dissimilar materials come together – can be sealed with caulk.
- The places where doors and windows close into their frames can be sealed with weatherstripping – cleverly designed strips of felt, rubber, metal, or plastic that fill the spaces around doors and windows, and compress when you shut them.
- Weatherstripping materials come in many styles. Some are self-sticking, so you don’t even need a hammer to install them. Others must be nailed on. Still others are crafted so pieces on the frame and the door lock together when the door closes.
- One of the trickiest places to weatherstrip is where the door meets the threshold. Special “shoes” and “sweeps” are available to stop these air leaks.
- Besides saving energy, weatherstripping and caulking have an additional benefit: By stopping drafts, they’ll make your home more comfortable.
Leak Patrol
- Some evening, when your house is at least 20°F warmer than the outdoors, hold your hand up to various places around windows and door frames. If you feel any drafts, the windows and door frames need weatherstripping.
- You can also use a smoking incense stick to look for drafts. Hold the stick near places you think might have cracks; if the smoke dances or gets sucked in, you’ve found a place to seal.
- Many of the biggest air sealing opportunities are up in the attic and below your floors. For these harder-to-reach leaks, it’s a good idea to call in a trained professional such as Recurve to quickly identify and remedy your home’s major leakage areas.

Leaking ducts can reduce the efficiency of your heating system by up to 20%. Ducts are a critical part of making your home energy efficient. If they’re leaking air – which they almost always do – or if they’re losing heat because they’re uninsulated, they’re contributing as much to global warming as they are to keeping you warm.
Energy Facts
- You can save up to 10% of your heating or cooling costs by insulating and tightening up ducts.
- Even if the air isn’t actually escaping from an uninsulated duct, you lose a lot of heat through its thin metal walls.
- When the first air that comes out of the vent after you turn on the heater is chilly, and stays chilly for a long time, you know your ducts are uninsulated and you’re wasting energy.
Simple Ways to Save Energy
If your ducts aren’t insulated: Turn on your furnace and feel for air escaping around the duct joints. If you feel any (and you probably will), hire a certified contractor such as Recurve to seal them with mastic.
If your ducts are already insulated: It’s harder to find out if your ducts leak. You can expose the joints (where the ducts bend, for instance) to check – but it’s best to leave it to an expert.
- Before you start examining your ducts, check to make sure the insulation isn’t asbestos (looks off-white, stiff, heavy cloth). If it is, stay away! It’s in your best interest to get it properly removed ASAP.

Respiratory allergies and asthma issues are very common, and both are made worse by breathing irritants in the air. However, it is possible to make sure the air you’re breathing at home is clean and free of the things that aggravate allergies and trigger asthma attacks.
Symptoms such as coughing and wheezing due to allergens or asthma triggers are a sign that your home is not healthy or performing well, especially if you’ve already taken measures such as getting rid of carpet.
The common culprit behind poor indoor air quality is dirty air being pulled into your home through an unsealed duct system or through other leakage areas. Since the duct system is usually in the crawlspace or attic, it can pull in outside pollutants (like ozone or pollen from outside or mold spores and dust from the attic) and trap them in your home. Sealing leaky ducts can often make a significant difference at home for people with allergies and asthma, but it is often overlooked as a solution. For the same reason, air sealing in the attic and crawlspace are also highly recommended.
It is also important to properly ventilate your home and clean/change your furnace filter regularly – or better yet, install a high efficiency air filtration system. If you take all of these steps, you can breathe easy knowing that the air in your home is healthy.
