3 BIG Tips for Maintaining An Efficient Wood Burning Furnace


wood boiler that needs wood burning furnace maintenanceThere are a lot of reasons to choose to invest in a wood burning furnace: minimal
utility bills, a renewable source of heating, a consistent cost without the ups and downs of the energy market, a steady supply of fuel (wood), low-cost warmth for a shed, home, stable, etc., etc.  One of the main reasons we hear from customers is long-term: they appreciate the long lifespan of an outdoor wood burner.  This reason comes with a caveat; you’ll get a longer (and safer) lifespan from your wood burning furnace if you use these tips for maintaining your wood burning furnace.

Keep up on your regular wood burner maintenance.

In addition to loading your wood burning furnace, make sure you maintain a schedule of regular wood maintenance, such as:

  • Regularly inspect your equipment for leaks and cracks.
  • Add water (as needed).
  • Clean out and dispose of ashes.
  • Clean your chimney and wood heater parts regularly.
  • Check your chimney flue and stovepipe for safety hazards (nests, hives, grass, etc.) every month.

This maintenance is important for the efficiency and safety of your wood burning furnace.  Maintaining your furnace also lengthens the life of your unit.

Be selective about firewood.

Whenever possible, only use seasoned wood for fuel. Seasoned wood is dried—usually by the sun and environment—for 6 months to a year (amount of time depends on species of wood).  You can usually tell wood is seasoned by it’s coloring; it is typically grey in color. Many people even say that it’s more important to have seasoned wood than to know the species of the wood. This is true to a point; there are some species of wood that burn better than others so it does pay to pay attention when selecting firewood. Once you’ve selected the wood, learn the basics of making a good, steady fire. Woodmaster has tips for building a good fire on their website under wood furnace maintenance.

Set some time aside in the spring for annual maintenance.

Once a year, your outdoor wood burner boiler needs annual maintenance that can keep your unit working well—and keep warming your building for a long time.

  • Drain and flush your boiler every spring (never leave your boiler without water).
  • Treat the water in your boiler once a year (usually in spring or fall).
  • Oil the fans.

8 Parts of Your Home You Need to Inspect Before Winter

home in winter after fall inspectionEven though the leaves are turning and temperature dropping, many Wisconsinites seem to be genuinely in denial about the prospect of snow.  While we don’t want o always admit that winter is coming, there is some wisdom in preparing the season—especially when it comes to your house.  If you want to limit your chance of emergency winter home repairs, a freezing hour of no heat, or an impromptu trip into your attic, it makes cents (pun intended) to start inspecting 10 key areas of your home before the first snow fall—and to start making repairs before winter.


Before the warm air from your furnace starts flying out the window when the temperatures drop, check around your doors (and windows!) for holes and cracks.  If you find any holes, fill in holes around your windows and doors with caulk.


Check for drafty windows, which cost you additional money on your energy bills. If you do suspect draftiness, hold a flame in front of the window. If the flame flickers, it’s time to think about replacing your window.

Air conditioner

Once you decide you won’t need AC any more, schedule an appointment to get your AC inspected, refrigerant refilled (if low), filter cleaned (if applicable), and maintenance done to make sure your air conditioner turns on next summer.  Even window air conditioners need cleaning to keep them going—and going efficiently.


Before you hit ‘heat’ on your thermostat, schedule an HVAC technician to maintain and inspect your furnace and ducts. An annual HVAC check up and maintenance can save you money over the winter; furnaces running inefficiently cost more to run and can cause a random breakdown, costing you more on your utility bills and for emergency repairs. Don’t forget to also change your furnace filter so it isn’t clogged when you turn it on. Once you turn your furnace on, change your furnace filter every month during the winter.


Extreme summer weather can damage shingles, and winter storms only make the damage worse. If you only have a few damaged shingles, a handyman or roofing company can make the repairs.  However, if a large area of your roof is damaged or too many shingles are warped or damaged, it may be time to get a new roof before the snow falls.


An estimated 35 percent of energy loss happens through your home’s roof. To prevent that loss and keep the cost of your energy bills low, inspect your attic to see if there is adequate insulation. If not, climb into your attic yourself, or hire a contractor to add insulation where your home needs it most.

As long as you are in the attic, check for signs of water leaks or areas where pests can come in.  Winter is the season notorious for infestations, so look for any holes big enough for a rodent or bat to come in.  Plug up any holes, or contact a pest company to secure your home against unwanted guests.


Don’t start a cozy fire on a cool fall day without making sure it’s safe for a fire. Contact chimney professionals to schedule an inspection so you can prevent carbon monoxide build up or a fire.

Smoke Detectors

You don’t have to wait for daylight savings time to keep your family safe. Test your smoke detectors and practice evacuating your home. Change any detectors with low batteries.

6 Ways to Fight Your Indoor Allergies

Pretty woman blowing nose from allergiesThe temperatures are starting to decline, and everyone’s time inside is on the rise.  One study we saw estimated Americans spend 90% of their time indoors—which can be very difficult if you are one of the 55% of Americans that have tested positive for an allergy to indoor allergens.  That makes fall a very crucial time for indoor allergy sufferers who want to rid their home of those evil allergens so they can spend their time indoors allergy-symptom free.

Buy a vacuum that removes allergens.

Besides price, size, and energy source (battery pack or electric), add another factor into your vacuum purchase: an allergy-friendly vacuum. Look for a vacuum with a HEPA filter or double bag to ensure that you can remove allergens from your home—and dispose of them without having an allergy attack.

Clean your ducts.

Indoor allergy symptoms can be exacerbated by common indoor allergens such as dust mites, pet dander, and mold. Every time you turn on your furnace or air conditioner, all of those allergens re-circulate though your home through your air ducts. To avoid the build up and recirculation or indoor allergens, schedule an annual duct cleaning.

Look for a furnace filter with a high MERV.

Furnace filters with a high Minimum Efficiency Reporting Value (MERV) catch finer particles circulating in the air, including allergens.  Be careful, though; filters with high MERVs (the max is 16) can add pressure on your furnace fan and possibly damage your furnace. If you are considering a filter with a high MERV, make sure to consult a HVAC technician to make adjustments for a high MERV filter.

Take the next step to cleaner air: purify.

If you have allergies, particles in the air that can trigger symptoms that make daily living difficult. The American College of Allergists states that 50% of illnesses are aggravated by poor indoor air quality, including allergies. Home air purifiers remove allergens from the air and can be installed as part of your HVAC system. If you are interested in an air purifier, contact the professionals to determine what air purifier would work best for your home and get a quote for air purifying equipment and installation.

Control your home’s humidity.

Rooms with humidity above 50 percent can breed mold, mildew, and dust mites that trigger indoor allergy symptoms.  Use a humidistat to monitor your home’s humidity.  If you are concerned about high home humidity, contact a technician who can lay out your options for a whole-home dehumidifier that maintains a healthy room humidity.

Wash and clean your favorite places.

Look hard at the common places you sit and lay in during your everyday life.  Schedule an upholstery cleaning for your favorite chairs and couches.  Wash your bed sheets on a regular basis—all the places where dust mites, pet dander, or other allergens may be, and where they can trigger your indoor allergy symptoms.

The Step(s) Every Homeowner Should Take When Your AC is Done

technician working on ACWhen we can finally make it through a day in Wisconsin—and night—without sweating, it’s time to shut down your AC unit for the year and (eventually) get the furnace fired up.  What many homeowners miss is the step in between—the maintenance that keeps your air conditioner in peak condition and ready to turn on next year when you need.  Once you’re done with your central air conditioner, every homeowner should:

  • Turn off the power to the air conditioner. Replace or clean your AC filter. Use a hose to rinse the filter and remove the dust.
  • Trim bushes and trees so all vegetation is at least 2 feet away from the unit.
  • (Carefully) clean the coils of your central AC unit. Brush away dirt, and spray the coils with a coil cleaner.
  • Clean your drain lines.
  • Lubricate where needed, and make sure that all screws, plugs, hoses, clamps and other hardware stay serviceable.
  • Turn the power back on and test your air conditioner. If it doesn’t work properly, call your HVAC company.

If you don’t have the time or expertise to do the maintenance on your air conditioner, contact a HVAC company to schedule a AC maintenance appointment.  Ductless mini-split air conditioners also need clean filters to work efficiently, so make sure you clean them on a regular basis and contact your local HVAC company to see if more work is needed.  If you have a window AC unit, bring your AC unit in to get maintenance done—and ready your home for the next hot summer day when you desperately need air conditioning.

3 Air Conditioners for Homes without Ducts

woman wipes the sweat from brow because of no AC in home with boiler heatingIf you were blessed with radiant heating and a boiler or a home with wood heating, there is still hope for you on the hottest, most humid summer days: ductless air conditioners that keep you cool during the heat.  Today, thanks to all the advances in air conditioning technology, you don’t need ducts to cool your home during the hot summer months—and you have a few ductless air conditioning options to choose from.  Here is the good and bad of modern air conditioners specifically designed for homes without ducts.

Portable Air Conditioners

What they are: Portable air conditioners are floor units with a flexible pipe and attachment that vents outside (through your windows).  Portable AC units draw air in, convert it to a liquid and then to a gas again to cool the air which it blows into the home.  Warm air is sent back outside.

Pros: Very small, easy to move around your home, very quiet, affordable cost

Cons: Poor energy efficiency, only cools a room or small area

Window Air Conditioner Units

What they are: Window air conditioner units are installed in a window (usually a double hung, though there are some models available for casements).  These units draw air in from outside and use refrigerants and blowers to cool and blow cool air into your home and draw warm air outside.

Pros: Easy to install and remove (though they are somewhat heavy), very affordable, doesn’t take up floor space like a portable AC unit

Cons: Poor energy efficiency, can usually only cool one room of a home if you have a lot of square footage

Ductless Mini-Split/Heat Pumps

minisplit heat pumpWhat they are: Heat pumps (also called mini-splits) draw in the hot or cool air from an exterior unit mounted outside, and the interior unit quietly blows the air into the home. In the summer, the exterior unit pulls cool air in to your home providing air conditioning during our hot, humid Wisconsin summers. During winter, they deliver a warm, comfortable heat even when temperatures are frigid. Because heat pumps don’t require much energy to transfer heat, heat pumps have an extremely low rate of electricity usage.

Pros: Very quiet, incredibly energy efficient, can be used for heating and cooling, usually has thermostat for energy efficiency, installed on the wall so it doesn’t take up square footage in your room

Cons: Most expensive ductless AC option, installation needs to be done by a professional

All three ductless AC options have filters that need to be cleaned out on a regular basis to keep them running efficiently.  If you have any other questions about air conditioners designed for homes without ducts, or find out the cost of a ductless mini-split, contact your local professionals to find the ductless cooling answer for your home.

7 Ways to Keep Your Home (and You!) Cool This Summer

young woman under hot sun trying to cool downThis hot, humid summer weather is the epitome of the saying, “It’s so hot you could fry an egg on the sidewalk.”  As tempting as it is to make outdoor breakfast eggs during this steamy weather, it’s even more appealing to look for fast relief—anything!—from this hot weather.

Stay away from the stove—and the oven.

Heat in your home is the enemy; this is not the time for baking cookies or putting a roast in the oven.  Instead, head outside to the grill for dinner or to the campfire for s’mores—two ways to keep the heat out of your house.

Look into air conditioning.

There are a lot of reasons people think that AC won’t work in their home, such as the budget or the lack of ducts in their house.  If the latter reason is an obstacle, there are options such as window air conditioners, portable AC units, or ductless mini-splits. To find out more about your air conditioner options and costs, consult your local HVAC professionals for more information.

Get wet.

There are a few ways you can cool yourself and your home down with water: 1) rinse a towel with cool water, wring it out, and put it around your neck; 2) get a towel wet with cool water, wring it out, and put it over a large fan (make sure it is not in contact with any electrical components); and 3) put a bowl of ice in front of a fan.  Any of these ways is guaranteed to cool you and your home down—even if just for a little while (like for a night?).

Hit the pool.

We admit, this won’t cool your home down, but a kiddie pool, community pool, hay bale pool (Google it for pictures)…any of these options can do wonders for your body temperature and give you a short reprieve from the heat. (Even a cool bath can help!)

Head to the basement.

If you have a lower level such as a basement—even a small one—head downstairs.  Unfortunately, if your basement feels moist, you probably won’t find much relief.  Dry air is cooler air (that’s how an air conditioner cools) and moist air feels sticky—as well as causing mold and mildew to grow and negatively impacting your air quality.  If you suspect the air in your basement is humid (too humid), look into buying a humidistat to determine the humidity level and a dehumidifier to dry the air.

Cool down with cool treats.

Frozen lemonade, popsicles, frozen yogurt, ice cream…there are a lot of summer treats that’ll make you feel cool even on the hottest of days.  Or head out to dinner at an air-conditioned restaurant for a good (and cool) meal.

Keep ceiling fans going (the right way).

If you have a ceiling fan, use it—and make sure the direction is optimal for keeping you cool.  A ceiling fan going in the counter clockwise direction during summer directs the cool air down on you when you need it the most. Add a few carefully placed fans in strategic places, especially in windows when the air is cool or around your bed at night, to drop your indoor temperature (and your body temperature!).

3 Common AC Problems & What to Do

thermometer with mercury going to scorching! from air conditioner problemsThis is not the time of the year to be dealing with a malfunctioning AC unit.  No matter what kind of air conditioner you have: central air, mini split/ductless, or a window unit, you need that refreshing dry, cool air when our humid summer air hits the mid-80’s and 90’s.  This is not the time for air conditioner problems or a break down—you feel like you’re going to melt!  It’s time for some AC troubleshooting so you can get back to your cool, air conditioned home.

Not turning on

This is one of the most common air conditioner problems for homeowners today, and one that could be (possibly) remedied without calling the professionals.  If you have a central air unit or mini split, check your thermostat.  Make sure it is turned to on, set for ‘cool,’ and that the temperature of the house is warm enough that the AC unit should turn on.

Next, check your electrical breaker box to make sure your air conditioner breaker is in the ‘on’ position. A faulty air conditioner can cause power surges that would cause the breaker to trip or the problem could be a fluke. Often, a breaker can trip for no reason. If the breaker trips repeatedly, you need to call an electrician to find out if the breaker is faulty.

In some cases, especially on high efficiency units, a dirty air filter could be the culprit.  Check your furnace filter, and swap it out with a clean filter (if dirty).  Dirty filters can clog your HVAC system and decrease the long-term efficiency of your unit—or even shut it down.

If none of these fixes remedy your problem, it’s time to call your local HVAC professionals to determine if you need to repair or replace parts in your AC unit.  If your problem has happened after hours, call an HVAC service that offers after hours service.

Shuts off and on

If your AC unit is turning off and on, your evaporator or condenser could be the issue.  These AC parts often get dirty or blocked from a lack of maintenance, and need a careful clean to start operating.  If you have a basic knowledge of your air conditioner, you can attempt the cleaning (but be careful of electrical parts, fins, and other equipment).  Otherwise, call an air conditioner technician to clean the unit and determine if the source of the problem requires repair or replacement.

Blowing hot air

An air conditioner blowing hot air is not an unusual problem—and it’s not a problem confined to just one kind of air conditioner.  When your mini split or central air conditioner starts blowing hot air, start by replacing or cleaning the filter.  For a mini split, pull the filter out of your unit and wash it.  For central air, change your furnace filter—and make sure you do so every 1-3 months depending on how often you need it.

If that doesn’t help your central AC or mini split, inspect your exterior unit.  If there is a lot of vegetation or tall weeds around your unit, clear them out and check to see if you need to see if your condenser is blocked or needs to be cleaned.

Your central AC unit may also need to have the refrigerant topped off or refilled. Refrigerant leaks are one of the top reasons that an air conditioner blows hot air. You’re going to need the HVAC technician for a refrigerant refill, so it’s time to make the call or email for professional assistance.

If your air conditioner issue occurs on a holiday or on the weekend, call the experts with 24/7 service hours for an emergency repair.  To keep from having to make too many emergency calls next year, remember to call for air conditioner maintenance in the fall or spring.  Annual air conditioner maintenance prevents problems that arise from a lack of maintenance, such as dirt and blockages.  Most importantly, air conditioner maintenance is another way to ensure that your unit turns on—and stays on so you don’t melt during the hottest time of the year.

5 (CLEAR) Signs It’s Time to Replace Your Air Conditioner

thermostat for lowering temperatures and energy billsIt’s hard to consider replacing your air conditioner when the unit is still (somewhat) working.  However, even when you’re still getting cool air from your AC, there are still situations where it’s makes cents (pun intended) to replace your air conditioner, such as:

You know your AC repairman too well.

If you know your favorite HVAC company’s phone number, or you and your HVAC technician know each other by first name, it may be time to put those dollars into a new air conditioner. The best way to determine that?  Ask your HVAC company for a free quote for a new unit; this gives you a dollar amount to decide if it’s time to stop throwing your money out the air.

Your energy bills go through the roof when you run your AC.

A habitual summer spike in your energy bills can be a clear sign that the energy efficiency of your AC unit is decreasing.  An inefficient unit has to work harder to cool your home, using more energy to do so—and more of your hard-earned money.

When determining whether it is time to invest in a new unit, consider the total cost and possible cost-savings of a more efficient AC unit. A more efficient AC unit keeps your home at your ideal temperature while not using as much energy as an older unit, potentially saving you money on your monthly energy bills.

Your AC is really loud.

An extremely loud, clattering AC is not by itself a sign of AC replacement, but it can be a signal of a more serious problem with your operational mechanisms.  Contact a HVAC repairman to determine the cause and severity of the problem.

Your refrigerant needs to be refilled regularly.

An occasional refrigerant refill is normal, but a consistent refill by your HVAC repairman should be a cause for concern—and is going to be a rising cost as your AC ages.  The type of refrigerant in your air conditioner depends on the type and age of your AC unit. In the past, AC units were most commonly produced with R22. If your system is an R22 system, it’s important to ensure that it’s not leaking because refrigerant R22 which is harmful to our atmosphere (and costly to refill as production decreases). Systems that are older than 15 years, especially those that leak, really need to be replaced with a current high efficiency R410a system.

Your home is hot—and moist.

A properly-working air conditioner keeps your home cool and dehumidifies your air.  If the opposite is true in your home, or your home’s humidity increases at random, it may be time for a new AC unit.

Your home is dusty.

There’s no way the cleanliness of your home could be related to replacing your AC, right?  Wrong.  If your home is always dusty no matter how much you clean, the problem could be your home’s duct system.  Contact your HVAC company to investigate the issue, and to see if a new AC unit could fix the problem.  They can help you calculate the cost and cents saved with a new AC unit.

6 Mistakes That’ll Drive Up Your Energy Costs this Summer

pink piggy bank surrounded by stacks of dollar bills spent on energy bills for coolingJust because summer temperatures are spiking doesn’t mean your energy bills have to skyrocket too.  Unfortunately they do every summer—largely due to residents who unintentionally make mistakes that make their electricity and gas bills go through the roof.

Not buying a programmable thermostat.

A programmable thermostat allows you to raise the temperature when you are away and gives you a cool home when you are home. In addition to having a cool home to come home to, this simple change can lower your bills by more than 5% annually.

Ignoring your old rickety, inefficient AC.

If your air conditioner is more than 10 years old, and is showing signs of inefficiency, stop wasting money on keeping your old unit running.  Consider a new, high efficiency AC unit to cut your cooling costs; you find out how much a new unit can cost by requesting a free quote. Today’s high efficient AC units are quieter, use less energy and run more efficiently than older air conditioners.

Letting your cool air fly out the window.

Keep your cool air where you need it: inside your house. Cover old, drafty windows with plastic, or get a quote from a contractor for replacement. Caulk any holes you find in the wood around your windows and doors, and replace any rotting wood.

Ignoring your air conditioner maintenance.

Air conditioners need annual maintenance to run efficiently, such as cleaning AC parts, removing debris, clearing out drain lines, and refilling coolant if needed. A clogged or poorly maintained air conditioner uses more energy simply because it needs to work harder to inefficiently cool your home.

Letting your ceiling fans sit idle.

To keep your home cool, your ceiling fans should be set to the counter clockwise direction during summer. A ceiling fan going in the counter clockwise direction during summer circulates the cool air throughout your home and directs the cool air down on you.

Ignoring your dirty furnace filter.

This is a mantra you should live by all year long, winter and summer. A dirty furnace filter can clog up the system, keeping your system from efficiently circulating cool air in the summer and warm air during the winter.

Why won’t my AC turn on?

Young woman in sunglasses calling for HVAC service for broken AC and sun shines behind her backWhen the temperature starts to rise, or our famous Midwestern humidity spikes, nothing feels better than the sweet cool air from an air conditioner.  It always seems like that’s when your air conditioner goes on the fritz.  If you’re one of those homeowners desperately trying to get your central air to turn on—with no success—here are a few checks before you make that emergency call to your AC service technician.

Check the thermostat.

True story: our friend’s home started getting warm one summer day, leaving her frantically looking for the fix.  The source of the problem was actually her thermostat, which had been turned to ‘heat’ by her toddler.  While you may not have a curious toddler, double check your thermostat to make sure it is turned ‘on’ and set to ‘cool’ before you do your next check.

Check your circuit breaker.

A simple fix to your AC troubles (and the start of cool air!) could be in your home’s electrical panel.  Head to your panel and look for any switches in the “off” position.  Click that breaker to the “on” position.  If the breaker immediately flicks off after you’ve switched it on—or does so a short time later—the problem is more serious and may require a service call from your local HVAC technician or electrician.

Check the outside unit.

If the first two checks don’t get your AC blowing cool air, head outside.  Some air conditioners have switches on the outside unit or mounted to your home.  Check to see if your unit has a switch and that it is turned “on.”

Check your air filter.

dirty furnace filterIn some cases, especially in high efficiency units, a dirty air filter could be the culprit.  Check your furnace filter, and swap it out with a clean filter (if dirty).  Dirty filters can clog your HVAC system and decrease the long-term efficiency of your unit—or even shut it down.  To remember to change out your furnace filter, set a regular alarm in your tablet or smart phone or set your high-efficiency unit to text or email you when a new filter is needed.

If none of these checks yield anything awry, or if your ‘fix’ only works for a short time, it’s time to call the local air conditioning pros.  Choose a company with 24-7 service so you can get some relief from the heat, and get some use out of your AC.
