Reap the benefits of effective residential AC duct cleaning

Reduced energy bills

If your heating and cooling system has to push air through dirty ducts and clogged filters, it will have to work harder and use up to 40% more electricity in order to perform the same tasks.

Fresh & healthy indoor air

Grimy HVAC systems will eventually start to distribute airborne dust and dirt through the rest of your home. This can have negative long-term effects on your and your loved ones’ health.

Longer equipment life

Dust buildup can cause short-circuiting and overheating issues that can irreparably damage expensive electronics such as computers, TVs, game consoles, and other sensitive devices.

Less need for repairs

Without regular maintenance, which includes AC duct cleaning, your HVAC system will develop issues that may cause it to break down more often and even significantly shorten its life.

Frequently Asked Questions

Very much so. Residential air conditioning duct cleaning addresses dust, dirt, mold, and toxin buildup inside your heating and cooling vents that can potentially endanger your health, drive up your energy bills, and damage your HVAC equipment and other belongings in Newmarket. This makes it a crucial part of home maintenance.

Yes. Dust, toxin, mold, allergen, and general grime buildup inside heating and cooling vents can reduce your indoor air quality at your Newmarket property and aggravate respiratory issues such as asthma and allergies, and cause headaches, sinus congestion, dizziness, and a variety of other problems. Residential AC duct cleaning directly addresses this problem.

The recommended frequency is once every 2-3 years for most homes in Newmarket. However, if your property is located near a busy road, close to a construction site, or in a downtown area, you may need to book residential air conditioning duct cleanings more often.

No. Residential AC duct cleaning is a complex task that requires the use of bulky and specialized hardware that most homeowners don’t have access to and aren’t trained to use. That’s why this job should always be outsourced to the professionals.
