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.

by Rita, Scarborough on Twintech Heating and Cooling
We were so pleased with their service

When our old oil furnace finally broke down we decided it was time to finally convert to natural gas and finally install central air conditioning at the same time. Knowing it was going to be a significant investment for us, we wanted to make the right choice. Twintech came highly recommended by a friend and we were not disappointed. From the first contact with the salesperson, until the final touches on the installation, we were so pleased with their service. Everyone from the company was so friendly, efficient and a pleasure to deal with. Best of all, the cost was very competitive. We would certainly recommend Twintech to anyone requiring HVAC work in their home.

Within a couple of hours, we had a new unit up and running!

During the hottest week in the summer our old A/C decided to call it quits. I called Twintech Heating & Cooling after receiving a referral from a family member; came highly rated for being an honest, family-run business, who appreciates their customers. Dave was able to accommodate my hectic schedule and book a late evening appointment to walk through the specifics. Greg and Mitch arrived exactly on time a few days later, were very polite and friendly, and within a couple of hours had a new unit up and running. I also received a follow-up call to ensure we were happy with the Amana.

Professionally done and took care to cover all entry floors

Professionally done and took care to cover all entry floors to the house for the installers to remove the old furnace and install a new furnace.
I also made recommendations of the tankless water heater that we had installed and items to address. We did not know they also installed tankless water heaters.

by Bill, Pickering on Twintech Heating and Cooling
Proud to support this local company

Price was not the cheapest nor the most expensive of my quotes. It's the quality of the installation that makes for a good AC system. The twins' knowledge & professionalism was evident in the small details:
Very clean work. Greg made sure that the refrigerant level & temperature were correct. They reinstall the insulation & vapor barrier around the wall. The outside electrical cords were secured to the wall. Proud to support this local company. Thank you.

by Taz on Twintech Heating and Cooling
