Best Heating & Air Conditioning / HVAC In Keene

“What a great family business!
Davis Oil helped out a customer of mine, whose propane company let them run out of propane then, wanted to charge them an astronomical fee to deliver to them. Davis Oil came out, did a site evaluation, then they came out and installed the propane tanks the same day, so that the customer would not go without heat!“

“Ciardelli installed central air in my home. The two gentleman that was here for the last two days did a phenomenal job. The work looks very clean, they were professional, they take pride in their work and very respectful. I would not hire anyone else to do anything with my boilers, central air or propane. I have had nothing but positive experiences with everyone I encounter from Ciardelli.“

“Excellent company. Great value. Friendly staff. I could not be happier about my decision to switch to Dead River for my propane.“

“Update 12/23/25 I woke up, accidentally ran out of oil. 1 Phone call. Oil delivered and furnace reprimed in all of about 30 minutes. Wow.

Consistently the best price in Keene. Ten cent discount for cash/fast payment. Good people. I've only used their service once, but the fellow was competent. Who can ask for more? I'm confused about the below rating since I, almost always, just ask for the minimum fill which I think is 150 gallons and there's never been a charge for that. They do charge for emergency fills and fills less than minimum. Hey those trucks aren't free or cheap to run. Very helpful staff, in person and on the phone. Recommended. **updated 11-20. Had a oil water heater failure that I could not fix. Prompt response, superb tech who was very knowledgeable. Total cost much less than I had expected.“

“We replaced our water heater on Saturday, only to discover Sunday morning (Easter Sunday, no less!) we had no power going to it due to old corroded electrical lines. We called Ells Electric, honestly not expecting to hear from them on Easter, but they answered our call within minutes and came out within a half hour! They were not only gracious and knowledgeable, but speedy, efficient and very fairly priced. We'll NEVER call anyone ELSE but Ells in the future; thank you for your EXCEPTIONAL service, so very rare these days, and so very much appreciated!!!!!“

“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.“

“I had no heat on a Sunday,snowing like crazy and had to leave the state. They came out and confirmed my diagnosis and had it repaired by Monday afternoon. They drove to Nashua to get the part,and buy the way it was 0 degrees. When I got the billed I was pleasantly surprised how fair it was. L&G is the best by far,thank you so much.“
