Having your ducts cleaned by Coldflow is an investment in the health of your family, and it's one that you can't afford to overlook.

Keeping your home clean and your family safe

Even with regular scrubbing of your filter, your ducts will still need attention over time. Regular duct cleaning ensures that you’re only blowing clean, filtered air throughout your house. Over time, dust and other debris builds up in the ducting, meaning that every time you turn on the heater or air-conditioning, you’re blowing microscopic particles throughout the room. Not only does this look unsightly when it settles, it can also pose a hazard for anyone with allergies or respiratory issues such as asthma or nasal congestion, potentially making it harder for them to breathe.

It’s recommended that for the average sized home, you have your air conditioning ducts cleaned every three to five years. However, you should keep an eye out for tell-tale signs such as a visible dispersal of dust from the vents on activation or rapid build-up of debris in the filter.

Frequently Asked Questions 4 Benefits of Professional Duct Cleaning

Duct cleaning: the secret to a fresh smelling home

If you are noticing an increase in your home's odor and can't seem to find the source, it might be time for duct cleaning! Ducts help distribute fresh outside air throughout a building so when they're clogged with dust or dirt particles, this blocks ventilation causing bad smells.

Dirty ducts putting a damper on your home's performance?

Your air ducts have a better chance of staying clean if you regularly get rid them checked for dirt, dust and mold. The filters installed in these systems can also prevent any unwanted bacteria from getting into your home's living space as well!

Why duct cleaning is essential for good health

There is no doubt that having your ducts cleaned can have a positive impact on the health of those living in homes with inefficient systems. Air pollution from dirt and dust particles accumulating inside creates an environment where it becomes difficult for people to breathe freely, which may lead them down paths such as chronic bronchitis or emphysema over time if left unchecked.

Detect & Prevent Later Problems

Preventive maintenance is important to keep your HVAC system running smoothly and safely. Duct cleaning can identify potential problems before they become major issues, such as mold or moisture that could seriously damage the equipment itself; plus it's healthier for you too!

What Our Customers Are Saying

I just had my two units installed. Please pass on my thanks to Jared Wates, who provided the quote, and the team that installed the systems today. The installation team worked really hard, double-checked, if not triple-checked, and certainly made sure things were clean when they left. A very professional and courteous team.

Ray did an excellent job. As it turned out, the error that caused the problem was cleared when the power was off after the storm, but he still made sure the system was working properly by doing a really thorough check of everything. Very helpful, professional and clearly very keen to make sure the job was done properly. Great work!

Very likely, your team arrived on time. They worked quickly and efficiently, plus they were very friendly. They left our house as they found it , clean and tidy. Just one thing they left behind a piece of equipment which I'm sure they can use. It is no use to us, so it would be a shame to throw it out. Many Thanks.

I have always had very good service from Coldflow in the past and now at present and I would thoroughly recommend them to everyone who has airconditioning. As our house is relatively new at present, we are waiting to hear from the builders if our system is still under warranty, if it isnt we will certainly get back to you again.
