The ventilation system in the walls and ceilings of your house is often neglected as part of the overall comfort system. People focus on the heating and air conditioning, but ventilation misses out on the upgrades, tests, and repairs it needs.  A poor ventilation system can ruin the best AC or heater, create massive energy waste, and harm indoor air quality. 

What can you do about it? In fact, is there anything wrong with your ventilation system?

We can answer the second question easily with duct testing services. This will give us the data about the state of your ventilation system we need to know so we can decide what else needs to be done. Below are three major services we offer to improve your ventilation system.

How Can I Tell If I Have Leaking Air Ducts?

Leaks in the ductwork of a home are a major problem, and they are unfortunately one of those problems that often goes unnoticed or unrepaired for far too long. The consequences of leaking air ducts can be extremely high, so it’s important to know if your house has duct leakage. You can then arrange for a professional to seal the ducts and restore the integrity of the ventilation system.

Of course, that leads to the question of how to detect if you have duct leakage in the first place. The ducts are well-hidden within a home, so you can’t visually inspect them. But there are other signs you can watch for:

A drop in airflow from the vents

One of the immediate effects of leaks in the ductwork is that it lowers the air pressure in the ventilation system. Ducts must be kept airtight to maintain air pressure, and the consequence of a drop in air pressure is that the airflow from the vents will also drop. If you put your hand to the room vents and notice the airflow is weaker than normal, it may be duct leaks.

Uneven comfort around the house

Lower airflow will also mean rooms cool down/heat up slower, which will lower comfort around the house. This will happen unevenly: certain rooms will still feel normal, while hot and cold spots will appear in others. Duct leaks aren’t the only cause of uneven comfort, but it’s a serious problem no matter what the source.

Odd odors from the vents

Leaks in the ducts will allow air from closed-in spots of the home to infiltrate the ventilation system, such as between walls and from the attic. This will carry a musty and sometimes moldy odor to the rooms.

A rise in energy costs

The biggest chronic effect that duct leaks have on an HVAC system is that they place more stress on the blower, heater, and air conditioner. Around 30% of the air moving through the ductwork can disappear through leaks, and this is air you’ve already paid to heat/cool and push into the ventilation system. The HVAC system will need to put in extra work to overcome this deficit—and that means energy bills will rise. If you see steeper bills to heat and cool your house and you can’t account for the change, you probably have duct leaks.

Solving the Problem

If you suspect duct leaks, the next step is to contact our professionals. We will test the ventilation system to find out if it has leaks and how extensive they are. If you do have leaky ducts, the next step for us is to seal the leaks. We use a range of methods to ensure your ducts will be restored to airtight condition once more. (By the way, store-bought duct tape isn’t a method we use. This “duct tape” is not actually useful for ducts.)

It’s our job to help homeowners live green and save green. We’re one of the fastest-growing companies for helping people in Modesto enjoy healthier indoor lives while improving energy efficiency. That’s what going green is all about.

“So what does any of that have to do with duct sealing?” you might ask. Plenty! People often take their ductwork for granted when it comes to making green improvements on their homes, instead of focusing on the installation of air purifiers, energy recovery ventilators, and insulation improvements. But sealing leaky ducts is an essential step toward making an energy-inefficient house into a super-green money-saving machine.

The Problem With Leaky Ducts

Because you can’t see most of the ductwork in your house (nor do you want to), you won’t know how easy it is for the ducts to begin to leak air. Age, corrosion, insects, high air-pressure, objects moved around in the attic … all of these can lead to small air leaks starting in the ducts. And small leaks can create big problems:

  • Air loss: You can lose around 30% of the air moving through the ventilation system to these leaks. This means that air you’ve already paid to heat or cool is going to waste in closed-off sections of the house. Do you want to spend 30% of the money you use for the air conditioner to cool down the attic? Probably not, but you may be doing just that if you have leaky air ducts.
  • Extra wear and tear: Losing that much air from the ductwork means the heater and AC must put in extra work to replace it. Yes, that’s expensive; but it’s also extra strain placed in the HVAC system. The additional wear and tear will take years off the system’s lifespan and lead to additional repairs.
  • Weak airflow: The air pressure inside the ducts drops because of leaks, and this means low airflow coming from the vents. You’ll notice hot and cold spots around the home and a noteworthy decline in comfort because of compromised ducts.
  • Dirty air: Plenty of dust and debris can enter the ducts through these leaks, leading to a drop in air quality. The leaks also allow more humid air into the ventilation system, which not only affects comfort, it can lead to mold and mildew growth.

Duct Sealing to the Rescue!

You can see from the list how much trouble you’ll stop with sealed ducts. You’ll have healthier air, more energy-efficient HVAC equipment, and better comfort. Leaking air ducts are one of the principal problems our experts look for when we conduct a home energy audit—there are few places where a house wastes energy faster than through a leaky air duct system.

We offer duct sealing in Modesto, CA using the best tools. We can test your ducts and use special video camera inspection equipment to ensure we locate all the leaks and have them sealed up. Ask about a full energy audit for your house, and we’ll find the best ways that you can live green and save green.
