Reviews

The audit pinpointed exactly where our 1950s house was leaking heat. After sealing and insulation, our winter gas bills dropped noticeably.

Professional, punctual, and very thorough. The report was easy to understand and helped us plan phased upgrades without feeling overwhelmed.

— Lila Patel

They found hidden moisture and ventilation problems our contractor missed. Fixing them made our upstairs far more comfortable in both summer and winter.

A detailed close-up of a high-efficiency gas furnace and insulated ductwork in a clean, well-organized basement utility room. The metal surfaces of the furnace are smooth and brushed, with clearly visible energy rating labels and diagnostic ports, while the ductwork is tightly wrapped in silver reflective insulation with neat seams. Overhead LED shop lights cast bright, even illumination, creating crisp reflections and soft shadows that emphasize the precision of the installation. The concrete floor is spotless, with labeled piping and a neatly mounted smart thermostat hub on the adjacent wall. Shot at a slightly low angle in photographic realism, with sharp focus throughout, the mood is professional, technical, and trustworthy, highlighting the thoroughness of a building energy diagnostic.

An attic space showcasing thick, evenly distributed cellulose insulation between wooden joists, with clear air baffles and air-sealed penetrations around vents and wiring. The insulation appears fluffy and dense, in light beige tones contrasting with the warm, aged wood of the rafters. A single, efficient LED work light clipped to a rafter provides bright, focused lighting, casting defined yet soft-edged shadows that reveal texture and depth. In the distance, a sealed and insulated attic hatch stands slightly ajar, demonstrating proper weatherstripping. Captured from a low, slightly wide-angle perspective in photographic realism, the composition emphasizes the depth of the attic and the continuous insulation layer. The mood is calm and confident, communicating hidden improvements that enhance comfort and reduce energy bills.

Sealing

Air Sealing, key to an Efficient Home

Targeted air and duct sealing to stop drafts, reduce leaks, and boost HVAC efficiency throughout your Hudson Valley home.

A modern living room interior on a winter evening, showing a large triple-pane window with tightly closed, insulated cellular shades, a sleek, wall-mounted mini-split heat pump, and carefully sealed baseboards. The walls are painted a soft warm white, with medium-toned hardwood floors and a thick area rug adding visible comfort. Outdoor snow is visible as a soft blur beyond the glass, but the interior appears cozy and well-lit by a combination of warm recessed ceiling lights and a floor lamp. The lighting creates a gentle glow, with subtle reflections on the window glass indicating its multiple panes. Photographic realism from a slightly elevated, wide composition, with sharp focus across the room. The overall mood is comfortable, secure, and efficiently warm without any visible drafts.
