Professional Ductwork Repair Service in Huntsville

The ductwork is designed to be hidden from sight. But while this is great for your home’s aesthetics and safety, it makes detecting air leaks from damaged or worn-out ducts very difficult.

If you’ve already had your HVAC equipment checked and the technician doesn’t find anything wrong with your existing units, it is very likely the problem is with your air ducts. Inefficiencies in the duct system can cause your heating and cooling system to fail prematurely. Even minor ductwork issues can have a huge impact on the performance of your HVAC system and the cost of running it on a daily basis.

If you’re looking for duct testing or duct repair in Huntsville, Blake Brothers is here to help!

Our HVAC experts use cutting-edge diagnostic equipment to quickly figure out what’s wrong with your ductwork and then carry out successful repairs to make sure it doesn’t happen again.

Signs You Might Need Duct Repair

Most homeowners make the mistake of neglecting their ductwork until it is too late. The problem with ductwork is that once it reaches this stage, it’s usually too late to fix it.
Sometimes it’s hard to tell if your ducts need fixing because the symptoms aren’t immediately obvious. But if you’re aware of the warning signs of ductwork inefficiency, you may be able to spot and fix the problem before it causes you major trouble in the future.

1. Presence of dust around the air vents
Dust or dirt around your air vents is likely due to a problem with the filtration in your air ducts. As soon as you notice this, schedule for testing or air duct repair immediately. If these contaminants reach and build up in your HVAC unit, they can cause the system to malfunction and fail over time.

2. Sudden spike in your energy bills
An unexpected and drastic increase in your energy bill is a sure sign that your heating and cooling system is working too hard. This could be due to a duct leak or improper installation. If you find yourself in this situation, call a specialist to examine your ducts and decide whether you need air duct repair or replacement.

3. Stale, musty odors in your home
Ducts that aren’t properly insulated can become breeding grounds for mold and mildew, which cause unpleasant odors to spread around the house when the HVAC system is on. Mold and mildew can make breathing problems worse and speed up the wear and tear on your furniture. So, if you notice musty smells in your home, have a professional come inspect your ducts right away.

4. Weird sounds coming from your ductwork
If your HVAC system is making strange noises like whistling or metal banging, it’s likely because there is too much air flow or uneven air pressure in your ducts. They’re usually a sign that your ductwork is in need of repair or a thorough cleaning. Due to its complexity, the HVAC system should be serviced and repaired by trained technicians.

5. Uneven temperatures around your home
If some rooms in your home are warmer or colder than the others, there could be a problem with your ductwork. A buildup of excess dirt or even an animal infestation can block your air ducts and cause a disturbance in the airflow to a particular room, making it warmer. On the other hand, a duct leak or crack could send more air to one or several rooms and make them feel cooler than the other rooms in your house.

If you notice any of these indications of duct malfunction and inefficiency, get in touch with Blake Brothers for air duct testing. We have some of the best certified HVAC technicians in the area, so you can rest assured that your duct system is in capable hands.

Why is Duct Testing Important

You can lose up to 30% of the air in your ventilation system due to duct leaks, which is a tremendous amount of waste. To prevent this from happening, arrange for regular duct testing services with Blake Brothers Plumbing, Electrical, Heating, & Air.

As a rule of thumb, you should get your home’s air ducts tested every one to two years. Air ducts deteriorate over time, and if they were poorly installed to begin with, the effects of wear and tear tend to show much more quickly.

Regular duct testing and inspections allow you to spot issues at an early stage, when they are less expensive to fix. Every day that air leaks through your ducts costs you money, so don’t put off calling for professional testing and repair.

How Duct Testing is Performed

The HVAC team at Blake Brothers is equipped with the latest diagnostic tools, including power vacuums and specialized gauges, to ensure the accuracy of our duct testing service.

We start the duct testing process by sealing your registers and closing off your vents. Next, we use the power vacuum to increase the pressure within the ductwork and then check to see how well your ducts can hold the increased pressure. A rapid decrease in pressure indicates that your ventilation system has plenty of leaks.

The test results will give us valuable insight into the system’s integrity and what needs to be done to improve it. We will then recommend air duct repair or replacement if necessary.
