There is some disagreement within the industry about the best method for cleaning air ducts. The two schools of thought are the “negative air” approach and the rotary brush and vacuum approach. We believe that both air duct cleaning methods can achieve great results in most situations when performed properly by competent technicians. However, our focus has always been on high quality residential service. The type of residential duct work commonly used in homes in the South poses unique challenges to duct cleaners because it is soft, flexible, and does not go in straight lines. Firms using the negative air approach are especially challenged by this type of duct work, as that process was originally designed to work well on the rigid metal duct work commonly found in the North and in large commercial buildings. The tools used to agitate the duct work in negative air cleaning are very difficult to get all the way into your duct work and can damage the lining of the ducts we find in most residences in the greater Jacksonville area.
"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."
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.
If you’re concerned about dust, allergens or mold, it may be time to have your air ducts cleaned. The national average cost for air duct cleaning ranges from $190 to $250. Air duct cleaning costs will vary based on a number of factors such as your location in the country, the age and condition of your air ducts, the number of linear feet to be cleaned, and any repairs your ducts may need. HVAC cleaning companies should clearly outline what is included in their services and at what rate, so always make sure you understand and have a written agreement before work begins. Here are some examples of average air duct cleaning costs:
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.
How often you should clean your air ducts depends on your situation. If you or someone in the home has asthma or is acutely allergic to certain airborne materials or pollen, regular duct cleaning may be helpful. The Environmental Protection Agency doesn’t have an official position on the necessity of air duct cleaning unless the ducts have been contaminated by rodents, insects or mold, or you are aware of particles blowing out through the vents. The EPA recommends you have your air ducts cleaned on an as-needed basis. The National Air Duct Cleaners Association (NADCA) suggests having air ducts cleaned every three to five years.
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.
