What to expect
Indoor air quality systems cover MERV-13+ filtration, UV lights, whole-house dehumidifiers, ERVs and HRVs, and media air cleaners. Filter MERV rating must match what the blower can handle — a wrong filter can damage your system over time.
Indiana's continental climate produces 1,000-1,500 CDD summers and 5,500-6,000 HDD winters. Variable-speed gas furnaces are the comfort standard.

Frequently asked questions
What MERV rating should I use?
MERV 11-13 captures most allergens and is the residential sweet spot. MERV 16+ requires confirming your blower can handle the pressure drop — using too restrictive a filter damages the motor.
Do UV lights actually work?
Coil-mounted UV lights effectively kill mold on the evaporator coil, which improves drainage and efficiency. In-duct UV for air sterilization shows mixed evidence. Replace bulbs annually.
ERV vs HRV — which do I need?
HRV (heat recovery ventilator) for cold dry climates. ERV (energy recovery) for humid summers — it transfers some humidity along with heat, keeping the indoor air drier in summer and less dry in winter.
