Duct Sealing, Cleaning, Repair & Replacement in Dublin, CA

Your ductwork is an integral, but often ignored portion of your central heating and air conditioning system. You can have the finest furnace money can buy but without a quality duct system to deliver the heat it won’t do you much good. Your ductwork is located in one or both of the most isolated (and poorly maintained) spaces in your house: the crawlspace or the attic.

As a result, your ductwork will endure wear and tear and damage and you won’t notice, even though it may be quietly costing you hundreds of dollars in utility bills. Fortunately for your ductwork and your peace of mind, Moore Mechanical offers a variety of ductwork services including ductwork repairs, replacement, sealing and cleaning.

Repair and Replacement

Sometimes an older house will have old or original ductwork, or ductwork that was never installed properly in the first place. Perhaps it wasn’t fastened properly or strapped to the floor joists for support. Sometimes your ducts will be damaged during the course of owning your house. Ductwork that is aging or was not installed correctly can cause your heating system to not work effectively. This damage to your ductwork can cause the heated and cooled air to leak from the ducts; it may also cause health problems inside your home. Damage can occur from many things including rodents, movement, rust, or damage done to your ductwork from other work that has been completed in your home. Crushes, cracks, dust, and debris build up is all damage that needs to be repaired so that your ductwork works efficiently and effectively. We can repair or replace your ducts as necessary. If you are in need of ductwork repair or replacement in Dublin CA, the team at Moore Mechanical can help. Our trained technicians will repair or replace your ductwork so that is working correctly.

Types of Ductwork

Flexible Ductwork: Flexible duct is what is commonly used in most installations. It is a flexible round duct material, made so that sections will bend or angle in almost any direction. It consists of an accordion-type plastic liner that is surrounded by insulation.

AlumaFlex Ductwork: AlumaFlex ductwork is an aluminum product typically available in 6’ lengths. Some advantages include a more “rigid” duct that is impervious to varmints eating through. AlumaFlex with typically retain its lateral stiffness for many years, insuring no “sagging”, which can effect airflow. Some disadvantages are that AlumaFlex can crush like a can and not return to its original shape. This is a problem when service people are crawling under or over a ductwork system.

WireFlex R-6 Ductwork: Most homes today are fitted with an HVAC system that utilizes WireFlex ductwork which is typically found in attics and walls. WireFlex ductwork comes in 25’ length allowing for a quicker installation. It is also available in different levels of efficiency and quality. Insulation values available for WireFlex are both R-6 and R-8.

Fiberglass Reinforced WireFlex Ductwork: Fiberglass reinforced WireFlex ductwork is the highest quality ductwork available for a residential application. It is a fiberglass reinforced flex duct that comes with a lifetime limited warranty. This ductwork is extremely durable, comes with antimicrobial liner and is virtually impervious to critters eating through.

Galvanized Steel Ductwork: For many years, galvanized sheet metal ductwork was the norm. While this option is still available to homeowners, the cost is typically not worth the expense. Twenty six gage galvanized ductwork is required in any garage application due to fire codes.

What about Duct Testing / TITLE 24?

Moore Mechanical is dedicated to helping customers be proactive in energy savings. For this reason, we seal and test all new ductwork systems we install, repaired ductwork or when a customer requests verification of duct leakage on the existing ductwork system in order to make a decision on repairing or replacing.

Sealing Your Existing Ductwork

If rooms in your home take a long time to get to the desired temperature you may have an air leakage problem, and that means that it’s time to call Moore Mechanical Heating and Air Conditioning. If your ducts are leaking, you are most likely supplying air to your crawlspace or attic instead of the interior of your home. So, by getting your ducts sealed you can stop conditioning these undesired areas and save yourself a lot of utility bill heartache. A pressure test is a great way to reveal all airflow loss with mathematical precision.

 

In houses with forced air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 20 percent of the air that moves through the duct system is lost due to leaks and poorly sealed connections. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set.

Because some ducts are concealed in walls and between floors, repairing them can be difficult. However, exposed ducts in attics, basements, crawlspaces, and garages can be repaired by sealing the leaks with duct sealant. In addition, insulating ducts that run through spaces that get hot in summer or cold in winter (like attics, garages, or crawlspaces) can save significant amount energy.

Benefits of Duct Sealing

A duct system that is well-designed and properly sealed can make your home more comfortable, energy efficient, and safer.

Comfort: Sealing and insulating ducts can help with common comfort problems, such as rooms that are too hot in the summer or too cold in the winter.

Indoor Air Quality: Fumes from household and garden chemicals, insulation particles, and dust can enter your duct system, aggravating asthma and allergy problems. Sealing ducts can help improve indoor air quality by reducing the risk of pollutants entering ducts and circulating through your home.

Safety: During normal operation, gas appliances such as water heaters, clothes dryers, and furnaces release combustion gases (like carbon monoxide) through their ventilation systems. Leaky ductwork in your heating and cooling system may cause “back drafting,” where these gases are drawn back into the living space, rather than expelled to the outdoors. Sealing leaks can minimize this risk.

Save Money: Leaky ducts can reduce heating and cooling system efficiency by as much as 20 percent. Sealing and insulating ducts increases efficiency, lowers your energy bills, and can often pay for itself in energy savings. Plus, if you’re planning to install new heating and cooling equipment, a well-designed and sealed duct system may allow you to downsize to a smaller, less costly heating and cooling system that will provide better dehumidification.

Protect the Environment: Energy used in our homes often comes from the burning of fossil fuels at power plants, which contributes to smog, acid rain, and global warming. Simply put, the less energy we use in our homes, the less air pollution we generate. By sealing your ducts and reducing the amount of energy necessary to comfortably heat or cool your home, you can reduce the amount of air pollution generated.

 Cleaning Your Dirty Ductwork

Thank you for your interest in the duct cleaning services provided by Moore Mechanical Heating and Air Conditioning.

When you choose a licensed HVAC contractor to perform a duct cleaning at your home, you are insuring that the technicians are familiar with a heating and ductwork system, something that a carpet cleaning company cannot claim.

When/How Often Should Ductwork Be Cleaned?

Typically we recommend that ductwork be cleaned every 5-7 years. However, there are many factors in determining if you are in need of duct cleaning and how frequent the cleaning should be done.

A few of these include:

  • Smokers in the household
  • Pets that shed large amounts of hair and dander
  • Water contamination or damage to the HVAC system
  • Occupants with asthma or allergies
  • Home was recently remodeled or renovated
  • You have just moved into the home
  • Our Process
  • The Rotobrush System
  • Duration of Job

To start off, Moore Mechanicals technicians will perform a preliminary duct inspection at your home. We do this to make sure that all of the ductwork is in good condition and able to be cleaned. If there is any damage or disconnected ductwork we do not want to cause any additional damage during the cleaning process, therefore the inspection is always a good idea just to be safe. After the inspection is completed and the technicians determine that the ductwork is in good condition, they will start the duct cleaning. They will go to each vent individually to do the cleaning. To start, they remove the register/grill, tape off the area and insert the hose/brush into the duct. At this time, the machine is turned on and the hose is fed throughout the length of the duct run. While the hose is being fed through, the brush at the end of the hose is spinning and breaking loose all of the dirt and debris inside of the ductwork. This debris is then vacuumed back into the Rotobrush unit, eliminating the risk of it getting into your home. The technicians will continue this process at each vent including the large return air vent and ductwork. After the duct cleaning has been completed, the technicians will also clean your furnace blower compartment to insure that all components of the air distribution system have been cleaned. Finally, an antimicrobial spray will be applied to the ductwork to sanitize all of the ducts and provide you with a clean smelling home.

The system that Moore Mechanical has found most effective for duct cleaning is the Rotobrush. It is a portable unit that is brought directly into your home. The Rotobrush is a strong vacuum like system that is equipped with a long hose that has a rotating brush attached to the end. This hose is fed throughout the ductwork to provide cleaning. The system is equipped with an ultra-high efficient filter to capture any dust, making the entire process a very clean procedure. See the “process” below

The duration of the cleaning itself depends on the amount of ductwork, size of home and accessibility of ducts. An average home will typically take 3-4 hours to complete the full cleaning.
