I turned on the AC when he was finished and immediately saw black fuzz balls the size of marbles come out of several of the registers. He said that was expected since everything was shaken up. So much for describing the service as cleaning. I paid him and sent him on his way. I cannot imagine that this type of service is worthwhile in anything but a new house. Apparently in old houses such as mine I can expect that using a whole house humidifier in the winter followed by a great AC can loosen the soot. Maybe this is to be expected for the first few weeks of summer each year. I now have lined the inside of the registers with cheesecloth to catch the fuzz. I’ll see if it stops after a couple of weeks.
Capacitors -- Capacitors help your HVAC motor start from a standstill. Over time they can weaken. As they weaken, they cause the motor to run hotter. This can shorten the life expectancy of your motor. Once a capacitor fails, the whole motor will stop working. You usually won't notice that a capacitor has weakened until your motor stops turning on.
The letters in HVAC stand for heating, ventilation and air conditioning. An HVAC system enables you to regulate your home or building’s internal temperature (thermal control) for comfortable living and working. You can bring heat levels down in the summer and up in the winter, keeping your home or office livable year-round. HVAC systems can also help with humidity levels and regulate indoor air quality in a home or office. There are many types of HVAC systems and technologies available.
But Tim, doesn’t this mean that a less-than-honest air conditioning company can just charge what he wants and say that it’s a difficult job? No. You see, dishonest contractors, typically, aren’t the brightest people (I figure if you’re still reading this, you’re warming up to me so I’m taking off the training-wheels). They aren’t smart enough to take difficulty into account, and will probably get confused if you ask them about it. They will tell you things like, “that’s how much the unit costs,” or “California has a new law that magically adds $5,000 to the price.”  Trust me, follow your gut, and you’ll be able to tell who the honest contractors are...or just use one of our ASM-approved contractors.
In the middle of summer—even more so in North America—AC repairs are undoubtedly the last thing you want to have to think about. But that won’t keep them from taking place. Fortunately, Service Experts Heating & Air Conditioning is dedicated to completing expert quality AC repair, maintenance and installation throughout the North America area. We certainly don’t want you to be stuck in an uncomfortable home during the hottest days of summer.
As one of the duct cleaners that do it right it disgusts me to hear the horror stories some of my past customers have had with the companies using scare tactics, bait and switch schemes, and just plain intimidation to make a fast buck. The Ductz franchise as a whole has gone behind other "duct cleaners" in the last year to the tune of almost three-quarters of a million dollars. All of this expense could have been avoided had the customers been able to do some background research before hiring. NADCA is a great organization and should be a minimum requirement for finding a duct cleaner. Other great questions include "How long does the service take?" (2 techs, 4-5 hours for a small house, 7-9+ hours for a two system house), "Do you clean the entire system including all trunk lines and the air handler (blower motor and evaporator coil)?", "How do you validate the job you have done?" (before and after picture reports work great). Beware of duct cleaners that say their process will solve all your air quality concerns. Duct cleaning is one of several steps to take to rid your home of unwanted dust, dirt, mold, and other allergens.
I read your article with interest and think it is a good start. One service that is always talked about is fogging ductwork for sanitizing. Many companies offer this service for disinfecting or adding a clean smell to the ductwork. Before any chemical or disinfectant is used, please read the MSDS (Material Safety Data Sheet). You might be surprise on what you are putting into the air stream. This is a high profit service and should be explored thoroughly before purchasing,

Your contractor will do a load calculation to determine the proper central air conditioning unit for your home. This calculation accounts for the climate, size, shape and orientation of your home, as well as its square footage. A professional will also look at the insulation, windows, walls, floors and other materials that compose your home. He/she will then examine any leaks, seals and existing ducts or vents.

Some research suggests that cleaning heating and cooling system components (e.g., cooling coils, fans and heat exchangers) may improve the efficiency of your system, resulting in a longer operating life, as well as some energy and maintenance cost savings. However, little evidence exists that cleaning only the ducts will improve the efficiency of the system.
