HVAC maintenance takes one to two hours for a pro to complete every task. The actual time it’ll take will depend on the size of your HVAC system, whether it’s been regularly maintained, and if your tech identifies any repairs that need addressing. If you decide to DIY your HVAC maintenance, the process will likely take longer.

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

Return air ducts should generally not be installed in rooms with high humidity, contaminants, or strong odors. This includes bathrooms, kitchens, garages, closets, attics, and furnace or boiler rooms. Placing vents in these areas can draw moisture, fumes, odors, and potentially hazardous gases like carbon monoxide into your HVAC system, which can damage ductwork, promote mold growth, and compromise your home's indoor air quality and safety. According to the International Code Council, there are some exceptions. For example, a return duct may be placed in a kitchen if it is at least 10 feet away from cooking appliances and serves only that room. Similarly, a garage can have a return duct if it is part of a dedicated forced-air system that only serves the garage. For optimal performance, prioritize installing return air vents in central locations and rooms with consistent temperature needs, such as bedrooms and living spaces. If you are unsure, consult a professional duct installer for guidance.

If you discover a dead animal in your air ducts, address the issue promptly to prevent unpleasant odors and potential health hazards. Turn off your HVAC system to prevent further spread of contaminants and contact a professional HVAC technician or pest control specialist to remove the animal and clean the affected area. They have the tools and expertise to handle the situation, including removing and disinfecting contaminated ductwork. The technician will inspect the ducts for any damage or other issues that might have allowed the animal to enter.
