How to Inspect your Duct System

Furnaces and air conditioners are the source for all the comfort your HVAC system provides but none of that warm or cool air goes where it’s supposed to without your duct system. Making sure that system is running properly is an important part of keeping your home energy efficient and not causing any issues with your health. While professional expertise is always welcome there are a few things you can do to assess your ducts.


Take a Deep Look


Keep an eye on your vents when your system turns on – if dust or other debris gets blown out you may have issues deeper in the ductwork that may need to be cleaned out. To be sure take a look with a flashlight to see if there’s any buildup. While you’re looking check for evidence of moisture or mold or any droppings that might be due to rodents or other pests. If you notice these issues you should contact a qualified duct cleaning service. 


Find Leaks


Twenty to thirty percent of conditioned air gets lost before it reaches the end point through leaks in the system. Do a visual inspection of your ductwork to look for obvious holes and run your hand around duct connections to see if you can feel any air escaping from the system. You can use duct tape to seal off any holes or loose connections.


When in Doubt, Call a Pro


Through your inspections you may find a tangle or badly arranged ducts in your system. Do not attempt to fix them yourself but call in professionals who are familiar with that kind of work. Also, even after making some fixes yourself or even getting your ductwork cleaned you may have utility bills that are too high, or rooms that never seem comfortable or are difficult to heat or cool. In cases like that you’ll also need to call in an expert so they can assess your entire HVAC system. The problem may require a rerouting or professional sealing of your duct system in order to fix the issue and prevent it from occurring in the future.


Your duct system should never be neglected as it is a major player in keeping your home warm or cool. If you need professional assistance from HVAC professionals who specialize in maintenance, custom ductwork, and installation Twintech Heating and Cooling can help. Contact us today.

Very pleased with the installation of our new furnace and A/C unit. From quotation stage to the completion of the job Twintech was very professional.
Thank you for a job well done.

by Darren, Pickering on Twintech Heating and Cooling

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.

by Private User on Twintech Heating and Cooling

I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.

by Robert, Ajax on Twintech Heating and Cooling

We required a new HVAC replacement after running the old
system for 18 years.
Dave understood our requirements and gave us a quote that
covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.

by John Armstrong, Pickering on Twintech Heating and Cooling

I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !

by Aaron on Twintech Heating and Cooling

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

by Linda on Twintech Heating and Cooling

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

by Robert Rogers on Twintech Heating and Cooling

Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.

by Robert Mizuno on Twintech Heating and Cooling

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!

by Ruth on Twintech Heating and Cooling

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
