"I had an amazing experience with Northstar Restoration. I can say it started from my first contact speaking with their receptionist, then the owner and his wonderful staff. I purchase a new built property which was not cleaned properly, the place was left with dust particles mainly in unfinished basement which spread throughout the whole house. In addition, subcontractors did not use properly coverings so garage floor as well as carpets were impacted. The owner Jay came out and explained how they could help alleviate the issues we faced. He was very thorough in his assessment and presented the options. We ended up getting our garage concrete floor cleaned, basement concrete cleaned and all mechanicals wiped downed and heap vacuum, air ducts cleaned and carpet cleaned. This was a huge project split into 3 days. All of the his technicians were extremely knowledgable and thorough. Because the project was 3 days and different areas I had 6 different technicians they were ALL outstanding. I commend Jay and all of his staff for making this a wonderful experience I could not be more pleased with the outcome. And would not hesitate to use their services in the future if I had a need."

Air Duct Cleaning questions, answered by experts

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

The most common duct sizes used in residential homes are round ducts 6 to 12 inches in diameter. This size is small enough to be easily installed into walls and ceilings, yet is wide enough to allow for adequate airflow through the home. Improper duct sizing can cause HVAC issues, increased energy bills, and a drop in HVAC efficiency, which translates into a less comfortable home. 

The number of return air vents a house should have depends on its overall square footage. You'll need one supply vent and one return vent for every 100 to 150 square feet of living space. This means that, ideally, there should be at least one return air vent in every room. However, if the room is 100 square feet or larger, it's better to have two or three. A 2,000-square-foot home should have between 13 and 20 return air vents, in total.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

Yes, unfortunately, scorpions do come up through air vents on occasion if they’re not properly sealed. These pests are excellent at finding small openings and may use vents as a pathway to cooler areas inside, especially during hot weather. To prevent this, inspect your vents, seal any gaps, and install fine mesh screens where necessary.
