A/C Spring Cleaning Air Conditioner Tune-up

By Dave Trosdahl on April 10th, 2008

At Duct-911.com, we would love nothing more than to be able to help you save energy and save money by lower your heating and cooling costs while still helping you maintain a cool climate inside your home this summer.

A/C Spring Cleaning

When thinking about your furnace or air conditioner it is important to under stand that most central air conditioners have three basic parts:

  1. Compressor/Condenser – This is the outdoor unit that sits next to your home
  2. Evaporator/A-coil – an indoor unit which is located in the plenum (the duct work above your furnace).
  3. Duct work and air vents More

Worried About Having a Bad Duct Cleaning Experience?

By Dave Trosdahl on November 1st, 2007

We don’t blame you for being worried. Anytime you hire a stranger to come into your home it can be a little unnerving. And, as in any industry, there are companies that give our industry a bad rap. As a professional air duct cleaning company, I would like to mention a few things regarding hiring air duct cleaning companies. Check with the BBB, ask for RECENT referrals, join Angie’s List. These should be steps you take whenever you hire a service company to come into your home.

First, you need to understood in advance that $39 for anything is not cost justifiable. Throw that coupon out! Many people do not understand this. These companies have already started out the relationship under false pretenses. When it comes to duct cleaning, If the company is quoting a price it should state “whole-house” (who would partially clean their duct work?). If it does say whole-house, and you don’t agree to any upgrades, write the check out for the coupon amount and not a penny more! They will never pursue it in court, they know they are in the wrong.

Our air duct cleaning company offers a $99 “whole-house” special. It is not at all uncommon for our techs to leave a job with a $99 check. That’s all some people want or need. For others, they want the rotary brush method. That takes longer and we charge $189. Others also want their dryer vents cleaned. That’s another $65. We are not pushy, we show, explain and then let the customer decide. We like to think that we play fair. We don’t mislead you with an artificially low price, nor do we inflate the cost of a rather simple procedure by making it sound very complicated, dangerous, and high tech. We know that some people want this reassurance, we just don’t do it that way. Some shop at Wal-Mart, others want Saks Fifth Avenue.

We like using the “upgrade” method because it saves the customer money. This way, you don’t pay for things they don’t need. For example, if your furnace was just installed, you don’t need a furnace cleaning for one year from the date of install, so why pay for it? If you don’t have central air, a dirty chimney, or a dirty clothes dryer vent, why would you pay a lump sum which includes all that?

Lastly, I disagree with the EPA’s comment that air duct cleaning should take 4-6 hours. Our installers can install new ducts in 6-8 hours! Many of these expensive companies make a big production out of duct cleaning. They are only air ducts! This comes from a guy who has been in the home services/air duct cleaning business for many, many years!

Here’s the big picture.
– Because ducts are made of metal, they are typically much easier to clean than carpeting or fabric.
– No company will send two of their techs to your home for less than $100. When you add up all the expenses, the math doesn’t work. Our company plays the odds. We know that a large percentage of people will want other things cleaned when they see how dirty (and dangerous) the dust or lint build up in their vents can be.
– Read and re-read the coupon. Is their a limit on how many vents? If so, count them and tally it up. does the price include both the hot AND cold air returns, if not, ask how much this will add to the price. Is furnace cleaning included or how about your a/c if you have one?
– Ask the duct cleaning company if they will cover the vents. This will prevent dust from blowing around your home.
– If you want video, you are going to pay. It takes much longer. Again, remember…it’s duct work! Unless you expect to see something, or you are overly curious, or suspect you have a severe mold problem, this is usually just a scheme for duct cleaning companies to increase the overall ticket of their jobs. They will tell you it’s necessary, we think it’s just a gimmick.
– You should be able to tell if they are professionals within the first 15 minutes. If they are anything less than you expect, ask them to leave.

– Visit the bad service forum and read the good and bad experiences of others.

I hope this helps.

Fall is Here – Time for Air Duct Cleaning and Dryer Vent Cleaning

By Dave Trosdahl on September 22nd, 2007

Today is the last day of summer, so that means tomorrow must be the first day of the air duct cleaning and dryer vent cleaning season. Although anytime is a good time to clean your dyer vent or your air ducts, it seems that most people prefer fall. If you are one of those people, you might want to get on the air duct cleaning schedule sooner than later. Our company has already seen a “spike” in business and we expect to have a very busy fall.

Perhaps, the sudden increase in people wanting their air ducts or dryer vents cleaned is because it was so hot this summer. Even though an efficient air duct cleaning technician doesn’t leave the outside doors open for very long at all, I am sure that homeowners still don’t like the thought of seeing their air conditioning dollars floating out the door. The same holds true in really cold weather.

Either way, now is the perfect time for duct work cleaning, a thorough furnace tune-up and dryer vent cleaning. Having it done this time of year will give you the piece of mind and the added insurance you need, so that you can know you have taken all the right steps to prepare for winter.

If you live in the Maryland, Virginia or Washington D.C. area please call: 443-927-2400
If you live in the Minneapolis and Saint Paul (Twin Cities) area please call: 651-653-4704

We will be adding additional air duct cleaning service locations nation wide, so check back often. We would eventually like to offer everyone from Florida to California and from New York to Arizona our $99 “Whole-House” Air Duct Cleaning Special!

What to do When the Electricity Goes Off

By Dave Trosdahl on September 2nd, 2007

Today, with the electric service in most areas being as dependable as it is, some customers response to no power is total confusion. Electric companies say this is even more true in good weather. The fact of the matter is, the power can go off at any time for any number of reasons.

First of all, relax, it’s going to be okay. Even if it is the dead of winter, it takes hours for your house to cool off enough to cause any damage. Under normal circumstances, in winter, your furnace might not run for long periods of time. Besides, electrical power is typically restored in minutes, so other than being an inconvenience, there is usually no need for alarm. In the summer months you will simply be without refrigeration and air conditioning for a few minutes or hours. Simply limit the number of times you open outside doors and try not to open the refrigerator or freezer more than necessary. Everything will be back to normal in no time.

Then next thing you should do is check your main breaker or fuse panel. This is usually located somewhere in the house within eight feet of your electric meter, somewhere in the house (like the basement or utility room), or else outside on the side of the house or on a pole. If you don’t know where your main panel is, find it now. You can also listen to your meter for a slight humming noise to determine if electricity is flowing through it.

If your home is being monitored by an electronic alarm system, and you have been alerted of an outage, you should first verify that an outage exists before you call. Once you have established that your fuses are good and that the main breaker is on, then you should call your electric utility company. You should have your physical address ready as well as your phone number and ideally, your account number. If you live in a rural area, it doesn’t hurt to mention which village or township you are in either.

Most electric companies have people available to answer the phones at any time of the day or night. If you need to hold, be patient. If there has been a power outage, many people are perhaps calling to report the same problem. If you see or hear something which you think might have contributed to the power outage, like a tree on the line, sparking or the loud sound of a transformer being hit by lightening, you should share this information with the dispatcher. It will help the linemen isolate the problem.

To prepare for a possible power outage, have some flashlights and candles ready. If you live in a cold climate consider buying a portable kerosene heater. If you have these items, know where your main electrical panel is and how to tell if a fuse is blown or a breaker has been tripped, other than being temporarily inconvenienced, you will be just fine.

Heating & Cooling Installation Should be Left to the Professionals

By Dave Trosdahl on July 18th, 2007

By asking enough questions and really studying, it is true that nearly anyone can accomplish anything. This is true in the workplace and it is true at home. Often times though, upon completing the task the do-it-yourself-er (or the spouse or co-worker) will say something like; “We should have just hired someone to do it.”

In The HVAC (Heating Ventilation and Air Conditioning) world this is especially true. A do-it-yourself (DIY) approach is seldom worth the hassle of learning what installers study for 2 years in college and most importantly gain in the workplace.

In his article “Air Conditioning and Heat Installation Best Left to Experts” , Rolan Jefferson writes; “While just about anyone can fasten parts into place, not only is the efficiency in jeopardy, a faulty air conditioning and heating installation can also put the people in danger.”

For more information on heating and cooling installation or air duct cleaning you might want to check out the All About Air Duct Cleaning Blog while it’s main focus is air duct cleaning there are also some very helpful tips about heating and cooling installation.

Is Your HVAC System Wasting Money? – Steps to Save Energy

By Dave Trosdahl on April 21st, 2007

Whether you are concerned about rising energy costs, or simply wanting to do your part in conserving energy, here are some tips that will help you conserve energy:

  • Switch from incandescent bulbs to high efficiency and florescent bulb
  • Clean your HVAC system – clean air ducts, a-coils, furnace filters, air conditioners and the furnace
  • Adjust room temperature according to season
  • Evaluate energy usage when no one is home
  • Make sure all equipment is functioning as designed
  • Install weather stripping around doors and windows

These are just a few pointers, some of which are discussed in the San Diego Source’s article ’30 Easy Ways to Save Energy’:

The U.S. Environmental Protection Agency (EPA) estimates that the real estate management industry can reduce energy usage by up to 30 percent simply by improving building operating standards. If a 1 million-square-foot portfolio can reduce its energy consumption by just 10 percent, it would be the environmental equivalent of removing almost 5,000 cars off the road for one year.

Energy efficiency is easy — and doesn’t require significant capital expenditures to make a big difference in your operating expenses. Use this checklist to reduce the need for unscheduled maintenance and to make sure that you’re saving all you can. Start with the lowest cost efforts and use cumulative dollars saved to invest in larger improvements

Spring is Here and it’s Air Duct Cleaning Time!

By Dave Trosdahl on April 20th, 2007

Okay, anytime is a good time to have your air ducts cleaned if your ductwork is dirty. But with winter over, spring is a great time to clean your furnace, air conditioner, dryer vents, and of course your air ducts.

If you are live in Minnesota, your windows have been closed all winter and your furnace has been recirculating much of the same old, stale air. Perhaps you or someone in your house was sick and this winter and of course that means bacteria and other germs. This is often referred to as “sick building syndrome

Now would be a great time to clean the most important appliances in your home; the furnace and air ducts, the a/c and the clothes dryer.
