Indoor Air Quality Solutions for NH Homes

The EPA estimates indoor air can be 2–5 times more polluted than outdoor air. NH homeowners face specific challenges including seasonal allergens, mold from humidity, combustion byproducts from heating equipment, and VOCs from building materials. Copper Hound installs a comprehensive range of air quality systems to address these issues at the source.

Air Quality Products We Install

Whole-home air purifiers — HEPA and electronic filtration capturing particles down to 0.3 microns
UV germicidal systems — neutralize mold spores, bacteria, and viruses in your air handler
Whole-home dehumidifiers — maintains optimal 45–55% relative humidity automatically
Heat Recovery Ventilators (HRV) — fresh outdoor air while recovering 70–80% of exhaust heat
High-efficiency filter upgrades — MERV-13 filtration for compatible existing systems
Smart thermostats with air quality monitoring

NH-Specific Air Quality Concerns

Humidity and mold: NH's humid summers combined with modern airtight home construction create ideal mold conditions. A whole-home dehumidifier set to 50% relative humidity eliminates the conditions mold needs to survive.

Tight home syndrome: Energy-efficient NH homes seal out cold air — but also seal in stale air, CO2, and moisture. An HRV provides controlled fresh-air ventilation without sacrificing efficiency.

Frequently Asked Questions

A standard air filter passively captures particles as air flows through your HVAC. An active air purifier supplements filtration with UV irradiation or ionization to neutralize finer particles and biological contaminants that filters alone can't capture. The two work best together.

Portable dehumidifiers work for a single room but can't maintain whole-home humidity levels and require constant emptying. A whole-home unit integrated with your HVAC runs automatically and manages humidity throughout the entire house with greater efficiency.

A Heat Recovery Ventilator continuously exchanges stale indoor air for fresh outdoor air while recovering most of the thermal energy. Modern well-insulated NH homes can have dangerously low natural ventilation rates, making HRVs increasingly important.

UV-C germicidal lamps installed in your air handler expose passing air to ultraviolet light, which damages the DNA of mold spores, bacteria, and viruses, preventing reproduction. They're particularly effective at preventing mold on the wet indoor AC coil.
