Beyond Furnaces and AC Units

At Locketite, we don't just install furnaces and AC units – we build healthier environments. Most contractors overlook what's actually circulating through your home or business. We focus on the invisible threats: allergens, mold spores, bacteria, chemical pollutants, and lingering debris from past tenants. We specialize in indoor air quality, health, comfort, and energy efficiency.
