We just finished a whole-home upgrade in Exeter that turned a noisy, uneven house into a quietly comfortable haven. In just a few days we installed a modern system with a WiFi thermostat, set up a filter subscription, and enrolled the homeowner in a custom service plan to keep everything running smoothly. The result: steadier temperatures, far less noise, and predictable maintenance — real peace of mind for a busy growing family. With 35 years as a family owned & operated business and a near‑perfect Google rating, we stand behind every job. Ready to protect your investment? Learn more: https://wix.to/wqaTqxy

We’re feeling the heat — and we want to help. New Hampshire summers are getting warmer and more humid, and a Quilt ductless heat pump is the practical, low‑disruption upgrade many Seacoast homes need. No ductwork, quieter than window units, and room-by-room control with the Quilt Dial and app means less wasted energy and more comfort where you actually live.

Book through Key Heating & Cooling before June 30, 2026 and save $400 off per room on your Quilt installation. As a family-owned team with 35+ years serving New England, we stand behind a customer-first, 24-hour responsive service experience — and we’ll make the install clean, fast, and right for your home.
