Under normal conditions, standard-use residential ducts (HVAC systems) should be cleaned every three to five years. Usage, system age and condition, local air quality, and number of residents and pets can affect cleaning frequency needs. Harsher conditions might require cleaning as often as every two years. Obviously, if your system is not functioning properly or the output air quality is bad, consult a professional sooner rather than later to get a proper diagnosis.

Air McCall’s comprehensive Duct Cleaning process includes the use of a fogging machine to sanitize your duct system with an all-natural biocide that is harmless to you and your family, and your pets as well. Most companies use a sprayer (not a fogging machine) to try to sanitize the duct system but the sprayers are not effective to treat the entire duct system.
"Energy is consumed by HVAC systems through a number of processes. Air is typically distributed through the ductwork via an electrically‐powered fan. Cooling coils remove heat from the air. Heating coils add heat to the air. Through normal HVAC usage, particulates in the air slowlycollects on the surfaces of various HVAC components, resulting in a gradual loss of energy efficiency. Some loss of efficiency via a single dirty component may be minor. When the loss through each component is added up, however, the impact could be considerable. Generally, the greater the buildup, the greater the energy loss. Removal of the buildup of particulate on HVAC components restores energy performance to the system." 
Chances exist that lint that has in fact been restricting the exhaust vent over a prolonged time period can cause overheating which in turn can cause a fire. The establish of lint that occurs over a prolonged amount of time is not merely a fire threat, it is also a clothing dryer problem that gradually steals the energy efficiency of the clothes dryer and gradually cost you significantly more money.
I was lucky enough to have my AC lines clog up on a Sunday night. I called Waychoff's after hours emergency service and Erin got back to me within 5 minutes of my initial call. She was very friendly and explained different service options for my situation. Eric was my technician and was at my house within the hour. He was very knowledgeable, explained everything he was doing in detail, gave me tips and advice to help prolong the life of my unit and even let my dog crawl all over him and "help". He had me back up and running less than an hour after he arrived. If you want a company who knows what they are doing and has fast, affordable and friendly service, I would highly recommend Waychoff's!

To be honest, the price was much higher than I expected or planned for. But I was impressed by the thorough attention to detail, even in the inspection made before quoting a price, and the professionalism and devotion to quality service that I could see in Mr. Stewart and his team. I suspect that others may have convinced me to add services for an additional cost that were included with his service, so I decided to go for the quality he offered and we were very happy with his detailed and thorough cleaning. The tobacco odor removal in a separate residence was the only thing that didn't seem to be as effective as expected but he came back to try again so I appreciate that. Overall, we're very happy with the cleaning and highly recommend this company.
2 major problems:They had to return 3 times to fix the installation of a new A/C and then I still had to fix another problem after they left. I also had to explain to the technician the difference between a parallel and series electrical installation when he was installing the automatic cut off switches.They also insist on you buying an annual maintenance package, that can cost up to $ 300 per year, even after they sell you a 10 year parts and labor warranty and if you don't buy it, then they put you at the back of the service list when you call for a repair.Avoid this company. There are so many to choose from that this should not even be on your list.
Good, genuine company with lots of experience! I used Elite AC to replace an old unit for my grandmothers house. I don't know much about air conditioning so it was good to work with a trustworthy company who matched our needs from a financial standpoint and installed the unit promptly so my grandmother didn't have to deal with the heat. I worked with Joey who explained our options and helped us make a quick and informed decision. My grandmother loved him and asks how he is doing still. I'm happy he took the time to help us and we will continue to use them for any of our AC needs.
Of the cleaning services in which we are proud to be specialists, air duct cleaning is by far the one that requires the most trust between the consumer and the air duct cleaning service provider.  There are many unscrupulous air duct cleaning companies purporting to be something they are not, many advertisements using unrealistic scare tactics, and of course bait and switch tactics are prevalent in the industry.  You need to feel confident in the professionalism of the firm you hire to clean your air ducts because you are asking someone to clean the inside of your duct work, where it can be difficult to see the results of the job.
