Every year, the same thing happens. We roll out for our first round of spring AC tune-ups across the Twin Cities. We knock on doors, step into basements, head out to backyards, and take a good look at what winter left behind. And every year, we find a handful of issues that homeowners had no idea were waiting for them—issues that, left unchecked, would’ve turned into breakdowns, higher energy bills, or surprise repair calls right when they needed cool air the most. That’s why this blog isn’t just a checklist. It’s a heads-up.

May 06, 2025

If you’ve ever scheduled an AC tune-up and thought, “What exactly am I paying for?”—you’re not alone. You see a technician walk around your system, maybe spend some time outside by the unit, maybe poke around the thermostat—and then they leave. Sometimes without much of an explanation. It’s no wonder homeowners feel unsure about whether a tune-up is worth the money.

Let’s set the scene. It’s the first real scorcher of the season. The sun is high, the windows are shut tight, and you’ve got the whole family retreating indoors for relief. You reach for the thermostat, drop it a few degrees, and… nothing. No cool air. No steady hum. Just a weak breeze—and rising panic. That’s the moment most people call us. But it doesn’t have to be your story.

The goal of state governors is to have 20 million heat pumps installed by 2030. They announced their plans on January 19, 2023, in New York City. In 2020, only 4.8 million heat pumps were installed, according to RMI. Heat pumps are an energy-efficient alternative to air conditioners and furnaces. They replace these fossil-fueled powered machines, and they rely on electricity to transfer heat. The great thing about heat pumps is that they can heat or cool a building. Another advantage to using one is that you'll save money on your energy bill. According to the IEA (International Energy Agency), American consumers save up to $300 per year with heat pumps.

If your furnace is nearing the end of its life or had issues keeping your home sufficiently warm this past winter, now is a great time to think about replacing it. Furnaces typically only ever last around 15 years, and most units start to work less effectively and use more energy as they age. If your furnace is nearing the end of its life, you don't want to wait until winter to replace it since it could fail and leave you without heat for days. Replacing your furnace in the spring or summer is also a great way to save some money for reasons that we will now discuss.

Summer has arrived and it’s humid now – which means you may be battling humidity both outside and inside your home. Our warmer months bring humid air – which can cause problems for our health, our furnishings, and our energy bills. The solution includes purchasing a whole house dehumidifier to keep the air inside your home cool and comfortable in the summertime. While there are options for purchasing a standalone dehumidifier, these typically dehumidify one room at a time and require constant emptying of water tanks to keep going. Enter the whole house dehumidifier – which is connected to your HVAC vents and is a lower maintenance option. If you’ve been wondering about the benefits of going with a whole-house dehumidifier, then keep reading.

As the summer begins and the temperatures start to rise, the last thing you want to be doing is checking off that to-do list when it comes to home maintenance. Spending some time getting a few things done can lead to a more enjoyable summer and changing out your HVAC air filter is one of those tasks. Changing it at this time of year is the perfect way to prepare for heavier AC use in the summer, and the increase in seasonal allergy symptoms.

From the price of chicken at the grocery store to the price of gas at the pump, it’s getting more and more challenging to stay within the budget for simple necessities.

Just how ready is your AC system for another summer of virtually non-stop activity? Was it running like a champ last summer, right up until it was time to flip the switch over to your furnace? Or did it struggle to make it to the finish line? One more question, please. Are you more likely to replace your furnace or AC system only once it is beyond repair or earlier, such as when you lose confidence in its cooling power? That is a great reason to replace it. Here are four more:

There’s no right or wrong way to design a home floor plan. Very persuasive arguments can be made for open or cordoned-off floor plans alike.

Stop newspaper delivery – check. Shut off the water supply to prevent flooding – check. Have a neighbor keep an eye on your house and water your plants – check.

There was a time when you didn’t think twice about authorizing a refrigerant refill for your AC system. You just got it done. That’s when R-22 refrigerant (more commonly known as Freon) was $5 – $10 a pound.

When you come home on a hot and sticky day, you expect to trade those conditions for your own cool, comfortable surroundings. Then one day, things suddenly aren’t quite as cool and comfortable – if at all.

During the summer months, your central AC system is likely your favorite major appliance – with the fridge’s ice maker perhaps in second place. Yet the condenser – the system component of an AC system located outside of a house – isn’t exactly easy on the eyes.

Apr 27, 2020

When it’s time to replace your AC system with one that works a whole lot better, chances are the first thing on your mind is getting back to the “Ah!” effect. You know, that feeling you get when you return home on a blistering hot day, but everything is just as cool and comfortable as can be indoors.

What happens if you don’t swap out your summer and winter clothing as the seasons change? Not much, other than perhaps an overcrowded closet or dresser drawers.

If you have just one thermostat, you’re no doubt paying too much to heat and cool your home. After all, is every room and area of your home occupied all the time? In our experience, that’s rarely the case. So, as the logic goes, if you’re heating or cooling every room equally but many are unoccupied for hours at a time, your utility bills are higher than necessary. No two ways around it. There are two ways around it: whole-house zone control and programmable thermostats. Let’s have a look.

“I’m telling you, dear, all we need is central air and we can stop worrying about the heat AND the humidity! "Have you and your spouse ever had such a conversation? Many families do, especially when planning to switch to central air for the first time. Once you do, bingo – everything you wanted, including whole-house comfort and reduced indoor humidity. But like all good things, those benefits come to an end, too. Not all at once, mind you. Meaning it could take you a while to even notice the gradual changes. But sooner or later you will. First, you’ll find yourself lowering the thermostat to keep cool. Later, the humidity starts to spike so you lower the thermostat even more. After a while, no amount of adjustment is making a satisfactory difference.

Moderation isn’t always a good thing. If you train for a marathon but never run more than five miles at a time, how can you expect to run 26+? If you strive for C’s’ in school and study just enough to achieve your goal, have you succeeded – especially if you’re capable of more? The point is, that sometimes you need to push yourself to the limits. But then there’s indoor humidity, where too much or too little is of no practical value. Worse, extreme humidity levels can cause all sorts of problems.

Every season has its fair share of pros and cons. Summer, for example, means fun in the sun, but sometimes to excess when conditions become hot and steamy. Spring brings milder weather but is no walk in the park for allergy sufferers. And yet, what do all four seasons have in common? Each can help you stay on top of your home maintenance game. Here’s a handy seasonal checklist to help you spread out the work – and cost – to help keep your home in tip-top shape all year long.

Whether you’re a winter enthusiast or spend your time counting the days until spring, winter does have its moments. Like snuggling up and watching TV. The change of wardrobe that comes with the season. And maybe even the break you get from months of seemingly endless yard work. Still, while downtime can do a lot to pick you up, let’s not get too comfortable. Especially since there are a bunch of things that can go wrong with your home until warmer weather returns. Here are a few winter home maintenance tips that will hold you in good stead.

Most people spend about 90% of their time indoors. Doing the math, that’s 21.6 hours a day, with at least half of that time spent at home. Where are we going with this? Straight to this fact as provided by the EPA: indoor air, on average, is twice as polluted as outdoor air. So, if you struggle with allergies, asthma, and other respiratory ailments – especially within the confines of your own home – the causes can be all around you, literally. How can Bob Boldt HVAC help? With a whole-house air filtration system, one installed inside your HVAC ductwork. The filter is designed to trap 95% and more airborne pollutants. And that’s where they stay until you clean the filter, which only needs to be done every three to six months. As a result, you’ll breathe cleaner, healthier air with fewer respiratory problems to plague you.

Your furnace is meant to be felt, not smelled. A variation of an old saying, yes, but true, nonetheless. Back east where many homes are still heated with oil, wintertime odors are common. Here in Minnesota, we don’t have oil heat – mostly gas and electricity. When the heat is on, you shouldn’t be able to smell anything to do with that process. When you do, you can be reasonably sure your furnace needs attention. The following are the most common furnace-originated odors and their probable causes.

Have you heard the one about the furnace that lasted forever? Neither have we. Never mind a true-life story, even a joke would be stretching the truth way too far. The fact is, older furnaces were built to last 12-15 years, while modern heating systems – with proper care – can last up to 20 years. As a homeowner who depends on a furnace, it’s clearly in your best interest to keep yours running efficiently for as long as possible…and we’re here to demonstrate how to do just that. These Home Heating Tips Work!

Lots of things can make you feel cold all over. A cold shower, teaming up with the local Polar Bears Club on New Year’s Day, going outside without a jacket, or driving a convertible with the top down when you should know better. Now that’s cold! Do you know what else can chill you to the bone? That feeling you get when you open the latest heating bill. You want to get mad, but initially, you’re in a state of semi-shock, chilled to the very bone. So, what’s a budget-conscious homeowner to do? Our advice: read and follow these tips before running to the thermostat, which only will make things worse.

People say that if you like dry air, move to Arizona. Great advice, unless dry air happens to irritate the life out of you. Yet, dry indoor air is simply a fact of life with forced-air heating systems. Making matters worse is that with the cold air of Minnesota, rarely do you have windows open during the winter, so there the dry air sits and performs its dirty weeds. You know, things like dry skin, itchy eyes, sinus problems, static electricity, bloody noses, and more. Who needs all that nonsense, right? So, let’s now examine a few surefire ways to add some winter-time moisture to the air:

Many of our customers are perfectly comfortable with our number one recommendation for a replacement gas furnace. While that’s flattering and indicates a great deal of trust, we love it when you ask questions. That way, you’ll know that our recommendation isn’t made on a “just because” basis, but that we put a lot of thought into what we believe will suit you best. As such, we encourage you to do some homework before calling us to replace your aging furnace. Among other things, you’ll feel more comfortable with your decision.

A ceiling fan can be a smart-looking, functional, and versatile addition to any room. It offers a cool breeze on a hot summer day and pushes warm air down during cold weather months (when run in reverse), all while serving as a stylish decorative home accent. However, just like any other appliance in your home, it can get quite dirty and dingy, which not only looks unattractive but can lead to dust circulating in the air, noisy operation, and even motor damage. Take the proactive approach to ceil fan maintenance to ensure smooth and quiet operation.

Dry, itchy skin can be more than uncomfortable. It can be a persistent and nagging problem during the winter when you spend more time indoors and the air is drier – that’s what a furnace does. But dry skin problems don’t end at your front door. Once you step outside, you’re often greeted by the cold, dry wind which further strips away your skin’s natural oils. So, you can just sit around and take it or fight back to help keep your skin looking and feeling silky smooth. Here’s how.

Even though ductless air systems have been available in the U.S. since at least the 1990s, you’d think they were the latest and greatest trend judging by the number of phone calls they generate to our office. As wonderful as they are – especially in certain applications – some things just take longer to catch on than others. In case you’re new to the topic, ductless air (also called “wall-mounted air”) systems combine heating and cooling into one neat and energy-efficient package. And yet, unlike heat pumps, ductless air systems don’t deliver conditioned air through air ducts as the name suggests, but rather through wall-mounted blowers. These also can be floor-mounted.

An uninvited guest has taken up residence in your home and you probably don’t even know it. No, it’s not Aunt Edna or that pesky neighbor you can’t seem to shake, it’s mold. Mold can grow just about anywhere where moisture resides, including places you can’t see, can’t easily reach, or don’t include in your cleaning regimen. In addition to being unsightly, mold can cause and exacerbate respiratory issues, especially among people already dealing with allergy and asthma issues. Wondering where mold might be lurking in your home? Read on to find out.

If you dread bedtime because sleep feels like an impossible dream, you don’t have to take that lying down. Insomnia affects about 35% of all Americans.

Very few things can spike your electricity like running your AC system. But that doesn’t mean you need to sit back and take it, not when there are numerous ways to enhance your indoor comfort AND save money at the same time. Here are just a few of the ways you can accomplish both:

Your home and family are one of a kind, with wants, needs, and lifestyles all your own. So, when it comes to indoor comfort, why would you settle for a “one size fits all” new or replacement AC system? You shouldn’t, since factors like home design, family needs (especially those under medical care), and what your goals are – improved comfort, lower utility costs, or some combination of these and other factors – can make a difference in the type of system that is right for you.

How do you define “luxury?”Well, one we all can agree on is air conditioning, even if you’re abundantly used to enjoying its cooling pleasures. Then again, you can’t have central air conditioning without a network of air ducts, so what’s a family to do when cost or your home’s design won’t allow for air ducts? Are they stuck with window or portable units, or fans? Once upon a time, the answer would have been “yes”. But now there’s a clear and nearly irresistible alternative. It’s called a wall-mounted (or ductless) air system that provides cool and warm conditioned air, all in one super energy-efficient package. Just as their name suggests, wall-mounted systems don’t need ductwork to get the job done. Here’s more to love about them:

Here in Minnesota, you don’t need to be a meteorologist to accurately predict another hot, sticky summer day. You’re more interested in how hot, and how sticky. And yet as bad as outdoor conditions might be, there’s always the inside of your home where your central AC system keeps you nice and comfortable…until it doesn’t. Oh sure, you don’t give up on it right away. You might have it cleaned and inspected, perhaps even have your ducts re-sealed and the thermostat checked. And all the while you’re losing air conditioner efficiency, and your electricity bill keeps climbing higher until the “ouch” effect gets totally under your skin. Short of replacing your AC system, there are a bunch of things you can do to help reduce that big, mean electricity bill. Here are just a few to get you started.

It doesn’t take much to invite mold and mildew to grow and spread inside your home. An improperly vented bathroom, a plumbing leak that goes unchecked, or a damp basement are just a few. Mold and mildew can appear from human error, too – the kind you’re probably not even aware you’re making. Here are 6 common mistakes that promote the growth of mold and mildew and lead to all sorts of problems, like asthma and allergies, and all the symptoms associated with them…not to mention damage to your home.

Life has a way of letting us know when something’s not quite right. The “check engine” light on your car’s dash, the scratchy throat that foreshadows a wicked cold, or the emergency alert warning you of dangerous weather. If only all such warning signs were equally obvious as to their source and eventual outcome. Take your home AC system, for example. It may not “speak” as clearly as a scratchy throat, but it does have several ways of getting your attention. Your only job is to learn what they are, and what they might mean.

Apr 15, 2019

So, what’s it going to be this summer: Keep the AC off to save money on electricity or run your system full bore so you don’t miss a minute’s worth of comfort? Happily, life doesn’t always present us with such extreme choices – usually, there are points in between that help you strike the proper balance. As such, now you can enjoy maximum comfort without having to pawn your jewelry to afford the inevitable summertime increase in electricity. Here are some ways to keep your costs down.

Does your skin talk to you – maybe even yell as it cries out for soothing moisture? If so, you’re not alone, especially during the long, cold months of a Minnesota winter. While there are numerous potential causes of dry, itchy skin, dry indoor air is right up there among the leaders. You see, here in Minnesota, most of us heat our homes with forced air furnaces, and there’s no drier form of heat than that. In New England and other points East, by comparison, many homes are still equipped with boiler-based radiators and baseboard heating. And while the heat, in general, dries your skin out, a boiler is more forgiving than a furnace as it helps retain some measure of indoor humidity. Anyway, here we are in the Midwest, and the problem of dry skin remains. Here are some effective ways to relieve and replenish:

If you struggle with allergy and asthma problems, you already know they can be caused by a multitude of sources. From cashews to shellfish, bee stings, certain kinds of meds, and so much more, there’s no telling what might cause an allergic reaction. But let’s say, for example, that your primary allergy is to dust or pesticides. You can clean and dust your house all you want, but that doesn’t mean you’re going to remove the source of the problem. That’s because dust, pesticides, and a multitude of other allergy and asthma irritants collect inside home ductwork, and every time you turn on your furnace or AC system, they start blowing around and invading your living spaces. So, what’s a careful homeowner to do? You have “umpteen” remedies at your disposal, but for today, let’s explore just one of them: your floors.

Even one programmable thermostat can reduce your home heating and cooling costs by up to 10% per year. The trick is you have to use it faithfully, unlike 90% of US households.

For starters, there are four basic types of program settings:

Home is where the heart is, alright. But the heart has plenty of company, not the least of which are airborne contaminants. Maybe you can’t see them, but there they are. Causing allergy problems for some, revolving colds and flu-like symptoms for others, and creating all-around unpleasant conditions for everyone concerned.

Turn on the TV or radio, grab your Smart Phone, or open a new window on your tablet: the latest weather update is never more than a click or two away. But here’s the thing: right now, it’s pretty nice outdoors. But a friend just called and told you to brace yourself for the extreme cold not more than 14 hours away. You don’t want to believe it, but the weather report suggests your friend isn’t making this up. Ultimately, you decide it’s better to be safe than sorry. Except, what exactly does that mean? To help fill in the blanks, here are a few tips from Bob Boldt HVAC on how to prepare – indoors and out – for extreme-cold conditions.

Even if you have a brand-new furnace, you might still consider your heating costs to be too high. And if your furnace is upwards of 10 years or older, not only are you thinking about it, but your heating costs ARE also higher than they need to be. Here are 5 simple ways to cut them back down to size.

Ever run a marathon? If so, you know it takes an incredible amount of discipline, preparation, and commitment. Good for you if you can muster all that together, running marathons or otherwise. And yet isn’t all that effort exactly what you expect from your furnace every year? Of course! And you can tell yourself all you want: “Hey, that’s what it’s built for!” But that doesn’t mean it still can’t use a little help.

Static electricity is both a fascinating scientific phenomenon and an annoying fact of life. Essentially, it’s the result of static charges building along certain surfaces and discharging electric shock upon touch. While such encounters are usually harmless – however annoying they might be – static electricity also can harm sensitive electronics.

For many American families, Thanksgiving Day is steeped in the kind of traditions that add to the warmth and meaning of the occasion. From things as simple as participating in a road race to watching a full slate of NFL football games – not to mention the Macy’s Thanksgiving Day parade – Thanksgiving has a unique set of rituals and fun activities. That, in turn, inspired us to do some research on other family Thanksgiving traditions. Who knows, maybe you’d like to introduce one or more of these to your family:

“Come on, furnace, I know you can do it. ” Hey, dummy, where’s the heat?” How you’d like a swift kick right up your heat exchanger?!” Yes, at one time or another, many of us have attempted to cajole or bully our furnace either back to life or full capacity. It never works and never will, but sometimes you just can’t help yourself.

New heating systems are wonderful things. A top-of-the-line model, for example, can seal cracks in your ductwork, shore up window caulking, install weather stripping around your doors, and take other steps to ensure you get the most from it. Hold the phone…your heating system can’t do any of that. But it does rely on duct sealing and all the rest to achieve peak operating efficiency and maximum energy savings. That’s why, new or old, you owe it to yourself to give your heating every chance to succeed. And preventing heat loss is a great way to start.

When does fall and cooler weather finally settle into Eagan, MN, and neighboring communities? Pretty much when it feels like it. But when it does arrive, it can do so with a vengeance…and only THEN does winter follow. On the other hand, it’s not like you don’t already know that. What you may not realize, however, is ensuring that your heating system is just as ready for fall and winter as you are. Here at Bob Boldt HVAC , we perform multi-point cleanings and inspections designed to ensure enhanced system performance, fewer and less costly repairs, longer equipment life, reduced energy bills, and cleaner indoor air. And all for one very affordable fee. The following are just some of the steps we follow ruing preventive maintenance:

This might surprise you, but the most polluted air in America isn’t outdoors. It’s right inside where people live. Indoor air – on average – is twice as polluted as outdoor air and can be much worse than that.

Here’s a tale of “good and not so good”. First, the good part. Since 2010, all new AC systems have been equipped not with Freon, but an eco-friendly alternative generically known as R-410A refrigerant. Unlike Freon, it’s not ozone-depleting, and that’s good for everyone. And now for the part, you might not like. While Freon is still available to re-charge pre-2010 AC systems, the supply is rapidly dwindling. That trend is going to continue right up until 2020 when Freon will no longer be available, period.

Is your whole house air-conditioned except for your enclosed porch or 3-season room? And, if so, would you spend more time there if you didn’t have to rely on window fans, ceiling fans, or some other makeshift cooling device? Take it one step further and imagine turning that room into a year-round gathering place with no new construction or any other major changes…what would that do to your lifestyle? Well, that’s what you can accomplish with a new ductless air system from Bob Boldt HVAC .

If you’re a firm believer in leaving well enough alone, we’re confident we can change your mind, at least when it comes to caring for your central air conditioning system.

What’s not to like about spring, you say? Well, for many area residents, it means lugging their AC window units up from the basement and installing them in time for the cooling season. Many of them would have switched to central air by now, but they’ve been told there’s no room to install air ducts. Happy to say, the story doesn’t end there.

Here in Minnesota, we hanker for warmer weather all winter long. When it comes, we hanker for air conditioning since our summers can be just as brutally extreme as their opposites. Can you count on your AC system to deliver all the comfort you want? Not without the right amount of TLC. Here are a few ways to provide it:

HVAC Services Whether you’re looking for assistance with your heating, cooling, or ventilation system – maybe even all three – there are certain questions you want to ask to ensure you obtain the services of a reliable contractor. Everyone gets the “heating and cooling” part, but there is no universal awareness of the ventilation component of HVAC. Ventilation helps circulate and purify air, control moisture levels, remove unwanted smells, and prevent air stagnation. There are different types of home ventilation systems, but that’s a blog for another time. For now, let’s focus on what you need to know before making an informed decision on who to hire for your HVAC needs:

If your central air system was suffering, would you know it? Sooner or later, of course, you would. But without early detection, any damage is likely to get worse thus resulting in a bigger repair bill. To help prevent that, you’ll want to know some of the most common early warning signs that trouble is brewing.

Saving money on your energy bills is never a bad thing. The only question is, do you feel like you’re saving enough? That’s a question you’re bound to confront the next time you replace your air conditioning system. And here’s how that proposition works: save money on a system with a lower SEER rating or, save money every month on a system with a higher SEER rating. SEER, by the way, stands for Seasonal Energy Efficiency Ratio. It’s a ratio of the amount of cooling produced divided by the amount of electricity it takes to produce it. The higher the SEER, the greater the system’s energy efficiency. So sure, if you buy a 25 SEER system (just about as energy efficient as they come), you’re going to save tons of money. But you’ll also pay a good deal more for that system than you would, say, for a 16 SEER model, which also offers significantly greater energy efficiency than your current AC system.
