Contact us 24/7 for duct seal services

Hello, are you looking for a duct seal service in Santa Clarita? We are glad you bumped into us. 

In many homes with forced-air heating and cooling systems, duct networks are used to distribute conditioned air all through the house. However, unfortunately, due to different reasons, many homes lose approximately 20% of conditioned air through disconnected ducts, holes, cracks and leaks. 

And, sometimes, the homeowners do not even know this. 

With this, you will have trouble keeping your house comfortable, no matter how much you set and adjust your thermostat. 

In this case, the only possible savior would be getting duct sealing. But before you go searching for “duct sealing near me,” allow us to break everything down for you. 

Shall we get started? 

What is Duct Sealing?

Duct sealing is a process to prevent air loss from the air duct system. It, therefore, involves eliminating any loose connections, cracks and holes on your air duct system. 

Air ducts are designed to be air-tight to prevent any air leakage. However, it is expected that deterioration will occur after wear and tear. Also, the ducts supply forced air around your house. And if they work all year long, it is expected that they will develop holes and cracks. 

 In such cases, air escapes and does not get to the intended destination. For this reason, your HVAC system will have to work harder to cover the deficit that was lost. And this means one thing, more energy is used. 

Always ensure that your air ducts are well sealed to avoid such problems. 

What Does Air Duct Sealing Process Involve? 

When you contact us at HVAC Santa Clarita for duct sealing, we will follow the following process:

  • Licensed HVAC professionals will come on-site and access the entire system. 
  • Then, we will indicate trouble spots such as holes, disconnections and cracks. 
  • Next, we will find the most appropriate duct sealing method for your air ducts, depending on the material used in making your duct. 
  • Finally, we will give you a report on how to spot poorly connected ducts and other troubles on your duct system. We want you to know when to call for air duct sealing services. 

Why is Duct Seal Important 

Benefits of Duct Sealing Infographics

Your ductwork system may work well after installation. However, at some point, it will just need professional duct sealing. With the air pressure it handles, it is inevitable. 

Here is why you should get air duct sealing:

  • Regain energy efficiency: the air loss from the duct strains the heating and cooling system. It has to work overtime to cover up the lost air to achieve the desired temperature set on the thermostat. This will result in higher energy bills. Therefore, to regain energy efficiency, you need to seal the holes and gaps in the ductwork. 
  • Improved air quality: Air will slip in and out of the network with a faulty duct network. The air getting in can have pollutants, odor, moisture and contaminants. These can cancel all the air conditioning done by your heating and cooling system. And the final result will be indoor air pollution. 
  • Less wear and tear on your system: If you do not solve the issue on your stressed duct network, the wear and tear will advance and eventually get out of hand. And in such a case, you will need air duct replacement, which is more expensive than duct sealing. Therefore, if you notice any problems or leaks, get duct sealing services as soon as you can. 
  • Improve comfort in your home: When air leaks from the ductwork, there will be a drop in pressure in the HVAC system. This, in turn, will cause reduced airflow from the air vents, which will eventually undermine the comfort in your house. 

Tell-tale Signs you Need Duct Seal Services.

How will you know you need duct sealing services? How will you know it is time to contact HVAC Santa Clarita to come to fix the air leakage from your duct network? 

When you notice any of these, chances are high you need duct sealing:

  • An unexplained rise in monthly electricity bills, 
  • Poor air quality resulting in dusty surfaces, sneezing and triggered allergies, 
  • Moldy and musty odors, 
  • Rattling noise for the HVAC equipment, 
  • Decreased comfort in the house. 

Duct Seal Methods: How do we solve the Issues on Ductwork System

There are different methods we seal the gaps, wear and tear on your ductwork. However, the first step will be to establish where the trouble is. Establishing where precisely the problem is is not always as straightforward. This is why you need to have experienced technicians do it for you. 

 HVAC Santa Clarita experienced team members have been doing this for decades and will have no problem identifying the trouble spots.

After that, there are several solutions(1) we will administer to solve the gaps, wear and tear on your system. We discuss them in detail below. 

Duct Sealing Tape

Using duct sealing tape is one of the ways to seal a leaky air duct. It is vital to use HVAC-specific duct sealing tape, also known as aluminum foil tape. 

This sealing method is the cheapest, less time-consuming and preferred when the mess is not huge. However, it is not long-lasting, and you may need to call for duct sealing services sooner. 

 Also, if your duct network often gets dirty with dust and oil, duct tape is likely to fail

Mastic Duct Sealant

This is a gooey substance that will harden some time after an HVAC professional applies it on your HVAC ductwork

Using water-based mastic duct sealant is best as it dries up faster and lasts longer. An HVAC professional will first determine the size of your leak. And depending on that, they mix the mastic duct sealant with another product such as fiberglass mesh tape. 

 This is why it is necessary to have a professional perform this process for you. 

 Aeroseal Duct Sealant

Mastic duct sealant and tape are often used in areas that are easy to access. However, the aerosol duct sealing is used for difficult-to-access areas such as ceilings. This will help fill up the holes and cracks on areas that cannot be accessed easily. 

This process involves a technician blocking the vents and the registers to build up the air pressure. After that, computer technology identifies all cracks, holes and loose connections.

The next step will involve the technician determining how much leakage occurs. After this is done, the distribution of mastic sealant throughout the duct is done. This technology is precise to ensure the precise amount of sealant is used on areas with issues. 

Once this process is done, the HVAC professional will measure the performance of your ductwork. This is to compare the before and after results. And the goal is to ensure that there is no leakage at all.
