When winter hits Derry, a broken furnace or boiler isn’t just uncomfortable — it’s unsafe. Denary Plumbing, Heating & Cooling provides complete heating services to keep your family warm and your energy bills under control. We repair, replace, and maintain all major heating systems, including gas furnaces, oil boilers, heat pumps, and radiant floor heating.

Our approach starts with a detailed energy audit to identify inefficiencies. Many homes in Derry have oversized boilers or clogged burners that waste fuel. We’ll show you the data and recommend only what’s needed. If replacement makes sense, we’re certified installers for high-efficiency condensing boilers and modulating furnaces that can cut your heating bills by up to 30%.

We also offer 24/7 emergency repair for those frigid nights when your heat quits. Our trucks carry common parts for most major brands, so we often fix issues in one visit. Regular maintenance plans help prevent breakdowns and keep your warranty valid. As a Mass Saves partner, we help you access rebates for qualifying equipment. Trust Denary for heating that’s reliable, efficient, and affordable.

Summer heat in Derry demands a cooling system that won’t quit. Denary Plumbing, Heating & Cooling offers expert air conditioning installation, repair, and maintenance for homes and businesses. Whether you need central AC, ductless mini-splits, or a simple window unit replacement, our technicians deliver cool comfort without the runaround.

We start every AC job with a Manual J load calculation to correctly size your equipment — oversized units short-cycle and waste energy, while undersized units run constantly without dehumidifying properly. Our installs follow best practices for refrigerant charge, airflow, and duct sealing to maximize SEER ratings and lower your electric bills.

For older homes without ductwork, we recommend Mitsubishi or Fujitsu ductless heat pumps that provide both cooling and efficient heating. These systems are whisper-quiet and can be zoned room-by-room. During repairs, we diagnose quickly using digital gauges and thermal imaging. Same-day service is often available. And every cooling repair or installation comes with our clean, honest, upfront pricing and 1-year guarantee. Stay cool the Denary way.
