How to help keep your HVAC system clean during a renovation

81mmx home renovation

It is generally a very good idea to have your air ducts cleaned after doing renovations or new construction work on your home.

Air duct cleaning is a general maintenance item that should normally be done every three to four years on average, but is also done when and if you have ever  noticed mice or insects living in them. Poor airflow may also be a problem that would lead a homeowner to consider duct cleaning as well.

You might also want to consider cleaning your ducts if you just moved into a newly built home. No matter how careful the construction crew is, construction debris and even garbage of all kinds could end up in your ducts.

Some builders are very conscious about this, and have us clean the duct systems in all of the new houses they build. That’s because they want to provide a quality product all around. We’ve been doing duct cleaning for some builders for the last 25 years and more. Some builders in the GTA are pretty cheap though, and say they want to leave this to the new homeowner instead.

Don’t believe any builder who says you don’t need to clean the ducts in your new home. 99% of builders know everything about building your house but actually know nothing about duct cleaning. Everybody seems to think they’re an expert on this subject.

During new construction it rarely matters how careful your builder may be about protecting the new duct system… Dirt still gets in there! Besides, you’ve just spent a million dollars or so for a brand new house, so why wouldn’t you spend another $300 or so to get your ducts thoroughly cleaned and know that you’re starting off with an entirely fresh and clean system?

Other times during a renovation, the furnace filter gets so dirty during the process that the contractor will go and remove it. They do this because the filter gets so plugged with dirt that no air will even flow through it any more. But they keep running the furnace anyway, even without any air filter at all. They need heat so their drywall compound will dry. But the duct system and all your furnace components get extremely covered in dust. I have seen this many, many, many times.

If you are having trouble with airflow from your heating or cooling system, a duct cleaning will quite often solve the problem.

It is worth noting, however, that not every air flow problem can be solved by cleaning your ducts alone.

If you have heat everywhere else in the home but not in one or two rooms, it doesn’t necessarily mean you need your ducts cleaned. Check to see if there are any dampers closed, or if any return air vents in these rooms are blocked by carpets or furniture. Sometimes just keeping the door to the room open most of the time can make all the difference.

Air flow from any vent can be checked with a meter, and the readings are then compared to the other vents in your home. This helps the technician to balance the air duct system. If it is determined that any of the ducts are blocked with debris, which is often the case too, then cleaning of your entire duct system would be absolutely warranted.
