What’s Inside My Ductwork and Why Should I Have it Cleaned?

air ducts

Ever wonder what’s inside your home’s ductwork? Maybe you want to know, but you’re afraid of what you’ll find. Take a deep breath. Or don’t. Not until you know your ducts are clean. Then you can breathe easy knowing you’re inhaling safe, clean air.

Why should I schedule air duct cleaning?

Worst-case scenario, you could have harmful contaminants and microorganisms resting in your ducts, contaminating your indoor air. What goes in either lodges to the interior walls of your ductwork or disperses to other areas of your home. Bacteria, mildew, mold spores. Bugs, rodents, birds.

That’s just the living stuff.

Dust, fur, second-hand smoke. Are you the first owner of your home? Talk about stranger dander. If your ducts are dirty, no matter how much you clean or how many times you replace your furnace filter, your indoor air quality will suffer. Regardless of the air pollutants, it’s worth the peace of mind knowing the lungs of your HVAC system are clean and clear.

What does air duct cleaning involve?

Air duct cleaning involves a high-powered vacuum and specialized brushes. Your technician may cut out small holes in the ductwork so their cleaning equipment can dislodge and draw out all the particles and dust that may be hiding in there. Afterwards, they’ll seal the holes so your HVAC system remains airtight.

How often should I clean my ductwork?

Every three to five years or more, schedule duct cleaning service, especially if

  • You have pets.
  • You or your family suffer from respiratory problems.
  • You hear scurrying noises coming from your ceiling or walls.
  • Your supply registers emit dust when your heat or air conditioning turns on.
  • You’re remodeling your home or did so recently.

Heating & Cooling Two provides professional HVAC services along with a variety of hot deals and financing options. We also offer ductless mini split systems so you can heat and cool your home without worrying about dirty air ducts. Contact us to request a free estimate.

Do You Really Need a Whole House Humidifier?

whole house humidifier“Do I really…?” It’s a question we all ask for various reasons. Do I really need to eat another chocolate covered strawberry? Do I really need to go to the dentist? Do I really need a shower? Okay, maybe that’s going a bit too far, but the point stands. We’ll go out of our way to live comfortably, save money, and pursue convenience by distinguishing what we need from we can live without. So we come to our question: do you really need a whole house humidifier?

The short answer to that question is yes, if you experience some or all of the following:

  • You’re constantly scratching your skin.
  • Your asthma or allergies act up every winter.
  • Your roommate or partner complains about your exessive snoring.

What Does a New Furnace Cost?

new furnaceA furnace should last 15-20 years, but when it has run its course, there’s no avoiding a costly replacement. You can expect to drop anywhere from $2,000 to $6,000, depending on what type of furnace you purchase, what contractor you hire, how large your home is, and how smoothly installation goes. Before throwing your money at a new furnace and HVAC contractor, consider these four things:

The different types of furnaces

The cost of a new furnace depends on the energy source used to heat it. There are a few main types of furnaces based on what they use for fuel: gas, electric, oil, or propane. We offer Bryant gas furnaces, which are known for their energy savings, quiet performance, and long lifespan. Gas furnace models vary based on how often they turn on and off to heat a home to the temperature on the thermostat.

  • A single-stage gas furnace runs at one speed to heat the home.
  • A two-stage gas furnace heats the home by alternating between low and high heating stages.
  • A variable speed gas furnace has an adjustable blower that runs at different speeds to keep a uniform temperature.

Furnace features

Most furnaces on the market advertise quieter, more consistent, and energy-saving performance. Manufacturers accomplish this by adding noise reduction features like insulated cabinets. Different brands incorporate smart technology to increase the Annual Fuel Utilization Efficiency (AFUE) of their furnace models. The higher the AFUE percentage, the less fuel a furnace will use to heat your home.


If ductwork, vents, or filters aren’t installed or adjusted properly, your heating system will struggle to distribute warm air throughout your home. If your furnace is in a hard to reach location, it could take more time or be more difficult to install a new one, making your HVAC contractor charge more for installation. You may need new ductwork throughout your home to accommodate for an upgrade to a larger furnace or to fix leaks in your existing forced air system. Either way, you’ll want this crucial step done right, so do your research on the best HVAC contractor to hire.


Your HVAC contractor should be licensed and insured in your state and have reputable affiliations and testimonials. Check out more than one local HVAC contractor, so you can make sure you are getting a fair price. Don’t go with the lowest bid. They may be cheap, but lack quality service and craftsmanship.

High efficiency furnaces are more expensive up front but worth it in the long run. Heating & Cooling Two is a trusted HVAC contractor who’ll give you an honest, free estimate on a new furnace. We also offer a variety of hot deals and financing options. Contact us to request an estimate.

How to Choose an HVAC Contractor

how to choose an hvac contractor

When it comes to choosing an HVAC contractor, you should be as fussy as your child is when you try to persuade them to eat their greens. Your health, energy bill, comfort, and home upkeep depend on it. Learn how to choose an HVAC contractor with this simple checklist:

Initial evaluation

Potential contractors should offer a thorough home evaluation to determine the best heating and cooling solution. There are many factors that could affect the amount of work you need done and the price they’ll end up charging. An HVAC contractor should come to your home to measure it, check to see what kind of insulation you have, and inspect the duct system for leaks or loose segments. If they try to give you an estimate over the phone before they’ve been out to see your home in person, hang up and look elsewhere.

Licensing and experience

Your HVAC system uses some of the most expensive equipment in your home. You’ll want to make sure you hire a contractor who is educated, certified, and experienced in how electrical wiring, refrigerant, combustion systems, and airflow through heating ducts work. In Minnesota, mechanical contractors must have a bond filed and approved by the Department of Labor and Industry and be licensed according to local requirements. You should also check that their work is insured, so that you are protected in case of their injury or accidental damage to your home.

Pricing and quality

Check to see if the companies you are looking into offer rebates and special offers to offset the expense of HVAC equipment and repair. Also, keep in mind that the lowest price is not always the best. You’ll want a company that provides expertise in your equipment manufacturer of choice and correct, professional installation. It may cost you more, but it will save you money in the long run. Make sure they give you a written bid of the work, not a verbal contract. The bid should list everything that needs to be done and the price you can expect.

Referrals and reviews

Ask the company for references and call them. Check out their testimonials, Google reviews, and page on Angie’s list. Ask your friends, family, and neighbors for referrals. You can learn a lot about a company just by examining their reputation.

Contact Heating & Cooling Two for a free estimate. We specialize in energy-efficient Bryant furnaces and offer financing options, countless HVAC accessories, and maintenance packages for your convenience. Learn more about our highly skilled team, our affiliations, and company values. It pays to be fussy and choose a reputable HVAC contractor who cares about you.

When You Should Get a New Heating System

new heating system

It’s the New Year. The old has passed, the new has come…or it should. If you’ve been hanging on to your old heating system because you don’t want to spend the money to replace it or upgrade, you may want to consider letting it go and moving on. Especially if the following is true:

Your furnace or boiler is 15 years or older

If your furnace or boiler is nearing 15 years old, consider replacing to save up to 20 percent on energy and avoid a breakdown in the middle of winter. Give yourself time to research, purchase the right equipment, and take advantage of money-saving deals.

You’re frequently calling your HVAC technician for repairs

Don’t misunderstand us; the Heating & Cooling team loves hearing from and visiting with our clients. But we also care about your pocketbook and peace of mind. If your heating system keeps breaking down, a new one may save you money in the long run and alleviate the stress you experience every time it stops working.

Your heating bill is higher than normal

If you notice your heating bill is higher than what you’d normally pay in the winter, your system may not be running efficiently. Modern technology provides many options for a more energy efficient system, like radiant heating, geothermal heat pumps, and air source heat pumps.

Your furnace short cycles

If your furnace is too big for your home, it may turn on and off more than it’s supposed to and cause more wear on the system. In addition, a dirty filter may not be letting enough air pass over the heat exchanger, causing the furnace to overheat and turn on and off in short intervals. So first, check your filter to see if it needs to be changed, but if problems persist, you may want to consider replacing it.

There’s a crack in your heat exchanger

Short cycling, old age, or poor maintenance could cause the heat exchanger to crack. Your heat exchanger transfers heat from one fluid (liquid or gas) to another and heats the air that passes through your home. If there’s a crack in the heat exchanger, your furnace could leak carbon monoxide and other flue gases into the household air supply.

You notice excessive accumulation of dust

If you notice your home is accumulating more dust than is normal, your air ducts could have leaks and are pulling particles from the attics and spreading them throughout your home. Sealing them off or insulating them would keep dust out and prevent warm air from leaking into your attic.

Your home is never heated evenly

Newer heating systems can be programmed so they’ll heat only certain zones in the home, a convenient technology called zoned heating. With programmable thermostats, you can easily save money and be more comfortable.

When you call your HVAC technician to inspect your furnace, the last thing you want to hear is that you need to replace your heating system. But it may be your best option. Letting go is never easy; Heating & Cooling Two is here to help. With seasonal maintenance, a heating system kept in good shape can last up to 20 years. Contact us to request maintenance service or for a free estimate.

A Basic Guide to Replacing Your Furnace Filter

replacing your furnace filter

Do you get angry when you see a higher heating bill? How about when you find out that a simple task like not changing your furnace filter is what is costing you that extra money? It may be an annoying part of home maintenance, but if you don’t change your filter regularly, your furnace could overheat and shut down because it can’t get enough air to cool off. To keep your furnace (and you) from working harder just to heat your home, we’ve provided a basic guide to replacing your furnace filter.

When should you replace your furnace filter?

A dirty furnace filter will affect indoor air quality, so check it about once a month. If you can’t see light through your filter when you hold it up to a lamp, you should replace it. If you have animals, burn candles frequently, open doors and windows often, or smoke in the home, you’ll probably need to change your filter more often.

How to replace your furnace filter

  1. Turn off the furnace.
  2. Locate the filter. Consult your manual if you don’t know where the furnace filter is. Most filters are either
    1. In the blower compartment. To access, remove the furnace cover or lift up the lid to get inside.
    2. In the return air vent, built into the metal ductwork.
  3. Remove the existing filter. Pull on the tab or lip of the filter frame to slide it out. When you pull the old filter out, have a garbage bag on hand and slip it in carefully to avoid scattering dust around.
  4. Note the airflow direction. Your filter will have an arrow indicating which way it should be placed to properly filter the airflow from your ductwork. The direction of the arrow should be pointed toward the furnace fan. Mark this on the exterior of your furnace with a permanent marker. That way, you’ll always know which way to install your new filters.
  5. Determine the filter size. Take a picture of or write down the filter size printed on the cardboard frame. You can also find the size in your furnace manual or use a measuring tape to determine its dimensions: height, width, and thickness. If your filter has an aluminum or plastic frame, it’s reusable, meaning you can clean it with a vacuum and water.
  6. Purchase a filter. You can find them at home stores, hardware stores, or online.
  7. Install the new filter. Look for markings on your new filter that tell you which side should face the furnace to correctly filter air flow, then insert accordingly.
  8. Keep the receipt from your new filter and tape it to the furnace so you know when you’ll need to replace the filter again. Make sure to turn the furnace back on after you’ve replaced the filter.

If you are having trouble, just call us. Our technicians can walk you through the process. Contact Heating & Cooling Two to purchase a new filter or schedule maintenance for your furnace.

Why You Should Install a Zoned Heating System

zoned heating system

Brushing a bald head is pointless. So is making your furnace heat areas in your home that you don’t use or overheating areas that are already warm enough. You wouldn’t control all the lights in your house with one switch. You don’t turn on every faucet when you start the shower, either. So why control the heat for your entire home with one thermostat? A zoned heating system uses multiple thermostats so you don’t waste the heat your furnace produces.

What is HVAC zoning?

A zoned heating system uses a control panel, thermostats, and dampers to channel your furnace heat to certain rooms so you don’t have to heat the entire house to a certain temperature. These customizable temperature zones are independently controlled, each by their own thermostat. You can even get remote controls that let you adjust the temperature on individual floors or in specific areas without getting up from your living room couch.

How does a zoned heating system work?

Dampers control how much air can pass through the ductwork at a time, completely stop air, or redirect the air to other areas of the home. A control panel opens, closes, and adjusts the dampers based on the temperature you set on the thermostat and the readings of the temperature controllers in each room.

Why should I get a zoned heating system?

Certain areas of your home could be warmer or colder, even when your thermostat is set to automatically adjust the temperature. The upstairs can often be three to seven degrees warmer than downstairs because heat rises. You may want to control the temperature in certain areas of your home depending on the function of each room. A warm, cozy living room. A chill, crisp workout room or office.

Here’s why you may want to install a zoning system:

    • If you and other house occupants passive-aggressively change the thermostat when the other isn’t looking because you can’t agree on a temperature.
    • If you have rooms that you don’t use all the time or that feel stuffy.
    • If you have high ceilings or large windows.
    • If you have a sunroom that overheats.

With adjustable temperatures, you can lower your heating bills, increase your home comfort, and extend the life of your furnace. Heating & Cooling Two can’t give you a new head of hair, but we can install a zoning system for your home so your furnace isn’t as pointless as a bald man’s hairbrush.

9 Heating Questions You Didn’t Even Know to Ask

heating questions

Heating systems are a hot topic right now (no pun intended). Do you feel left out in the cold? We’ve compiled a list of commonly asked heating questions, so you can catch up:

How much does heating cost?

Your heating bill depends on both the size of your home and the weather. During chilly Minnesota winters, the average home’s heating cost is around 200 dollars per month.

What is the life expectancy of a furnace?

Furnaces typically last between 16 and 20 years. But if your furnace requires a lot of maintenance or doesn’t run efficiently, you may want to consider replacing it before it’s reached its maximum life.

Why is regular maintenance important?

Regular maintenance will ensure that your furnace is running efficiently and not wasting energy. Without proper maintenance, such as regular air filter changes, your furnace could be circulating allergens throughout your home. Equipment eventually wears down, and when it does, you’ll want to make sure you address any dangerous leaks or malfunctions that could lead to a fire or carbon monoxide poisoning.

What should I expect during a routine furnace inspection?

Your HVAC technician should inspect the vents and ductwork for leaks or blockages. They’ll check the heat exchanger and belts for any signs of wear, cracks, or corrosion. They’ll remove the blower wheel to clean it and test for a tight seal on the blower access door. In addition to lubricating all the motor’s parts, the technician will check and test all electrical components, including the safety controls, thermostat, burner, and flame sensor. Finally, your technician will check the furnace air filter and replace it if necessary.

What temperature should I set my thermostat to save the most money?

During the day, set your thermostat at 68 degrees. Most people sleep better when it’s cooler at night, so turn the temperature down to around 62 degrees before you crawl into bed.

How often should my heater turn on?

Most systems cycle two or three times per hour. However, if your furnace is constantly turning on and off, it could be shortcycling because the filter needs to be changed or some other component is malfuctioning. A clogged filter prevents your furnace from intaking enough air, causing it to overheat and turn off before it’s run its full cycle.

What should I do if I smell gas?

A gas leak could poison your family or cause an explosion if not detected and addressed properly. If you smell gas, evacuate the house immediately. Don’t use any electrical switches or appliances that use electricity. Do not turn on a flashlight or light a candle. Do not use the phone (including cell phones) or open a window. Go to a neighbor’s house and call 911 immediately. Do not return to the house until you’ve received the all-clear from a technician from your gas company.

What causes heat pumps to freeze?

A heat pump should have an automatic defrost cycle that keeps it from freezing. However, ice may build up on the coils if your filter is clogged, airflow through your ducts is restricted, or your outdoor unit is blocked by leaves, grass, or snow.

What should I do with this information?

Now that you know a bit more about your heating system, contact Heating & Cooling Two to schedule maintenance for your furnace. Our knowledgeable technicians can answer any other questions you have. We offer maintenance packages so you can save money on heating repair.

Why You Should Use a Home Humidifier in The Winter

home humidifier

If you feel a zap of static electricity every time you touch a lamp, fold your laundry, or brush your hair, chances are, your indoor air is too dry. Humidity can make the summer months feel unbearable, but in the winter, you may want to consider welcoming it back into your home. As the temperature lowers, air density increases and can’t retain as much water. Humidifiers put moisture back into the air so you can live comfortably in the brittle cold winter.

Avoid getting sick and heal more quickly when you do.

Dry air doesn’t just produce static electricity shock; it can aggravate respiratory problems and make the common cold even more uncomfortable. Asthma, bronchitis, and allergies can worsen in dry air, and airborne viruses travel and spread more quickly. Dry air can irritate your eyes and cause nosebleeds as your body struggles to maintain its fluids.
Moisture prevents the movement of germs after they are released into the air and decreases the time viruses survive. When you are sick, humidity can reduce coughing and sneezing and help you heal more quickly. Humidity keeps nasal passages clear, reducing snoring throughout the night so you can sleep better.

Keep your house in tiptop shape.

Humidity helps maintain the physical condition of your home so you can save money on repairs and your heating bill. Dry air damages wood and can cause your doors or wood furniture to crack. Depending on the temperature and humidity levels, wood can expand and contract, loosening joints in furniture and making wood doors hard to shut. Humidity can make the temperature feel warmer, so you can turn down the thermostat and save on heating bills.

How much humidity is too much?

Too much humidity can be unhealthy, too. If your home air is more than 50 percent humidity, mold and mildew could grow on the walls or in your ductwork. Make sure you keep the humidity level between 35 and 45 percent. Some thermostats come with a humidity sensor that automatically adjusts your home humidity.
Don’t live in a home where everything you touch sends a static electric shock through your body. Create an atmosphere where your hair obeys the laws of gravity. Heating & Cooling Two offers whole house humidifiers and humidifier filters to help you maintain optimum humidity levels in your home. Contact us for a free estimate.

What is HVAC, Anyway? | Heating & Cooling Two Services

What is HVAC

Don’t feel guilty if you don’t know what HVAC stands for—or how to pronounce the abbreviation (h-vac). Not many people know how an HVAC system supplies indoor air and maintains the environment inside their home. While it makes sense to leave installation and repair services to professional technicians, understanding the basics of HVAC can help you consider your options and save money.

What is HVAC, anyway?

HVAC stands for heating, ventilation, and air conditioning. Nearly every modern home, office, and industrial building has an HVAC system designed to regulate temperature and maintain indoor air quality, using components such as:

  • Furnaces
  • Compressors
  • Heat exchangers
  • Evaporator coils
  • Condensing units
  • Refrigerant lines
  • Air conditioners
  • Whole-home ventilators (fans)
  • Ductwork
  • Vents
  • Thermostats


Homes can be heated by gas or propane furnaces or water systems with boilers that use gas, oil, or fire. Depending on the system, heat is distributed through the ductwork, vents, or radiators. Some homeowners choose to install radiant floor heat systems as a second heating source.


Ventilation systems use fans, ducts, and vents to circulate the air throughout your home and provide each room with fresh oxygen for safe breathing. You can open your windows to increase air flow naturally, but that’s not an ideal solution in the winter months. Ventilation systems include bathroom and stove exhaust fans that carry out moisture and smoke to prevent mold and mildew growth. Filters, dehumidifiers, and humidifiers also improve the air quality in a home.

Air conditioning

Apart from just a window or wall A/C unit, most homes have a whole-house air conditioning system. Air conditioning can come in two forms: split systems and packaged systems. Split systems use an outdoor and indoor unit to cool the home; packaged systems come in an all-in-one, compact unit.

HVAC tips

Depending on the efficiency of your units, the size of the system in relation to your home, your local climate (in Minnesota, that’s a no-brainer), and how much you use it, the average monthly electric bill in the summer and winter can be well beyond a hundred dollars. Read our tips for an energy efficient home.
