A June 2025 customer described Brad replacing a failed tankless water heater through Decatur Heating Services, choosing a unit compatible with city gas and coordinating with Liberty to get it running. The customer praised the quote and pace of the work. The Keene company has an active New Hampshire Mechanical Business Entity license and advertises 24/7 emergency service. In another June 2025 account, a customer called about water leaking from a ceiling; the visiting workers assessed the situation and referred them to a plumber when the problem proved unrelated to HVAC. A January 2022 reviewer said two messages went unanswered. Google lists 4.7 stars from nine ratings, with written accounts dating from 2022 to 2025.
Typical your area range for this kind of work, from regional averages — not a quote from Decatur Heating Services. Use it to sanity-check bids, then get the real number in writing.
Estimated range
$5,000 – $11,400
Typical HVAC project around $8,200
The gentlemen from Decatur Heating Services answered my emergency call when water was leaking from my ceiling. They were prompt, great communicators, thorough, and assessed the situation well. They even provided references to a plumber when my problem was not HVAC related. I was three weeks away from having a new baby and extremely stressed about this situation and they helped ease my worries. They are very professional and I plan to call them if I have HVAC issues in the future.
When my tankless hot water heater died recently, Brad found time for me in his schedule, gave me a fair and prompt quote, installed the unit and coordinated with Liberty to get it up and running quickly. He also knows his stuff and headed off potential issues by quoting a unit that's actually compatible with city gas. Before connecting with Decatur I'd received an overpriced quote for an incompatible water heater from one of his competitors. So yeah, Decatur are prompt, reasonably priced and knowledgeable. Five stars.
