Why Proper Air Duct Installation Matters
The ducts in your home are the lifelines of your HVAC system. If they’re poorly installed or deteriorating, problems add up quickly:
- Uneven temperatures cause some rooms to feel warm while others remain cold.
- Air leaks waste conditioned air, forcing your AC to run longer.
- Excess humidity makes Miami homes feel sticky and uncomfortable.
- Dust and allergens spread more easily, lowering air quality.
- Energy bills spike as your HVAC system compensates.
