Common HVAC Noises You Should Be Aware Of

Are you suffering from unnecessary noise in your home? Are you having a hard time watching and hearing the TV because your vents are too loud? There are some noises that are normal, but there are also instances wherein HVAC systems make strange noises and can eventually become loud and disruptive annoyances in your home.


This does not have to be the case.


 Here are some of the common noises in an HVAC system and what can be done about them: RATTLING A ratting noise that comes from an HVAC system can mean a few things.


If it is coming from the outdoor unit, then there might be some kind of debris in the system like a twig.


Make sure to turn your system off, then remove the debris.


If there is visible damage to your outdoor unit, it is best to call for professional HVAC help.


 If the rattling is coming from the inside, do the same thing - turn your system off and call for a professional.


 HISSINGS A hissing noise can indicate that air is escaping from the system.


If the hissing noise is coming from the walls, then there is a good chance that your ducts are leaking.


Aside from making noise, this also wastes your money because the air that is meant to circulate your home is leaking into the walls instead.


If the hissing noise is getting louder, then call an HVAC technician.


 If you hear a slight hissing sound, on the other hand, the sound might be coming from your air vents.


It can be because your filter is not set right, or you probably have the wrong size filter, thus, creating a gap in the seal.


In such cases, you can have the right size of the filter and place it correctly to leave no room for gaps.


 CLANKING HVAC systems that are running normally will make a humming noise.


Clanking noises, however, can indicate that something is wrong.


There can be some loose parts such as the blades, pipes, or the blower motor fan that are rubbing against each other.


Clunking noises can be a more serious problem because the loose parts can cause costly damage to your system if not addressed accordingly.


Make sure to call a reliable HVAC technician immediately.


 BOTTOMLINE Keep in mind that your HVAC system needs regular maintenance tune-ups.


You should also change its air filters regularly, and if there are general repairs, then you must attend to them immediately.


Knowing what the normal sounds are from what is not normal can help you determine when something is not right.

Dave was great in helping me get the proper units for my property, as well as getting them installed. The installers arrived when they said they would, and completed the project on time, and professionally. If I needed another furnace, I would use Dave again.

by Ed B., Whitby on Twintech Heating and Cooling

I have known Greg and Grant Dainty for many years and have used their company for my house and business. I recommended them also for my parents and sister and they all have been very satisfied with the quality of work for a reasonable price. I just recently had them install a new HVAC system in an older house and was very pleased with their work. Craig in Pickering. After meeting with various heating and air conditioning contractors I was referred to Twin Tech Heating and Cooling through a family member. Greg and Grant arrived at my home and provided me with an estimate and a plan as to how they were going to remove and replace my furnace and air conditioner. On the day of install Greg and Grant arrived at my home on time and were very professional and extremely courteous as to any questions or concerns that I had. The removal and install was truly professional and the attention to detail was exactly what I was looking for. I’ve seen many installs from other contractors and I couldn’t be any happier to have had such a clean looking install. The sheet metal work, ducting and venting all look fantastic. Upon completion Greg and Grant left me feeling extremely happy and very fortunate of a job well done. Thanks again Twin Tech!!

My old furnace had finally broken down for the last time when contacted twintech to have a new furnace installed…They were prompt, knowledgeable and very reasonably priced. They did such a great job i tell all my friends and family about this company.

by Damien McIsaac. Ajax on Twintech Heating and Cooling

To whom it may concern, I recently had TwinTech (Greg and Grant Dainty) replace my furnace and service both my gas fireplaces and air conditioning unit. They were professional, courteous and very fair in their pricing. I would gladly recommend TwinTech to anyone needing work done. I can be contacted at 905-626-XXXX.

by Blair N. - Toronto on Twintech Heating and Cooling

My Fiancé and I have relied on Twintech Heating and Cooling now for the better part of the last 10 years. In that time, Greg has installed a furnace, an air conditioner, and a heat-pump at our residence in Toronto. In each instance Greg and his team were a pleasure to deal with. They were courteous and professional throughout the whole process and the quality of their work is first rate. Our experiences have always been extremely positive and we have referred his services numerous times to our friends and family. Without hesitation, I would recommend Greg and TwinTech Heating and Cooling to anyone looking to service or replace their existing heat/AC equipment

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!
