Air ducts are often out of sight, out of mind—but that doesn’t mean they’re problem-free. Cracks, clogs, leaks, or even mold inside your ductwork can quietly impact your indoor air quality, raise your energy bills, and put added strain on your HVAC system. At Mainstream Electric, Heating, Cooling & Plumbing, we provide detailed air duct inspection services—including advanced camera inspections—to make sure your ducts are clean, sealed, and flowing the way they should.
Serving Spokane and Northern Idaho since 2000, we help homeowners uncover hidden ductwork issues early—before they lead to poor performance, expensive repairs, or health concerns. Because when it comes to your comfort, it’s what’s inside that counts.
A professional air duct inspection is a thorough assessment of the internal condition of your home’s ductwork. During the process, our licensed HVAC technicians examine your ducts for:
Dust and debris buildup
Leaks or disconnected joints
Mold or mildew growth
Damaged insulation
Airflow imbalances or blockages
At Mainstream, we also offer duct camera inspections, using small high-definition cameras to see deep into your duct system. This gives you a clear view of what’s going on—no guesswork, just visible proof. Whether you’re experiencing musty smells, hot and cold spots, or higher utility bills, a duct inspection can help you get to the root of the problem.
Even small duct issues can lead to big problems. When ducts are leaky, dirty, or blocked, your HVAC system has to work harder to deliver conditioned air, which drives up energy use and shortens the life of your equipment. Meanwhile, contaminants like dust, allergens, and mold can circulate freely through your vents—affecting your family’s respiratory health and overall comfort.
If you’ve recently completed a remodel, have an older home, or haven’t had your ducts checked in several years, it may be time to schedule a professional air duct inspection. It’s one of the most affordable, preventative steps you can take to improve indoor air quality and energy efficiency.
At Mainstream, we know that what you don’t see can hurt your comfort—and your budget. That’s why our duct inspections are never rushed or superficial. Our team takes the time to walk you through what we find and explain all of your options clearly and honestly. We’ve proudly served Spokane families for over 20 years, offering dependable HVAC and indoor air quality services with a neighborly touch.
If we find any concerns, we’ll help you move forward with confidence—whether that means duct sealing, air duct cleaning, or improving ventilation in hard-to-reach areas of your home. Plus, we offer 24/7 emergency HVAC service, so you’re never left waiting when comfort matters most.
Your ductwork plays a major role in your home’s air circulation—but it’s just one piece of the air quality puzzle. At Mainstream, we provide comprehensive solutions that work together to create a healthier, more comfortable living environment:
