Big Al's Services, LLC

Nobody writes about Big Al's Services without naming Al. Across five years of reviews he turns up by name — diagnosing the furnace, explaining which parts have to go, quoting the price before the work starts. The trade is oil-fired heating first and cooling second: boiler and furnace installation, oil tank installation and removal, annual cleanings and routine maintenance, AC mini-splits, and 24/7 emergency calls. The Better Business Bureau grades the company A and lists it as an accredited business, and records two New Hampshire licence numbers for it — the directory's claim, not a verified status. Speed is the recurring theme. A customer writing in August 2023 called on a 90-degree day with a clogged AC drain line flooding the basement floor and had the unit fixed within 20 minutes for $150. Writing in January 2021, another hired the company to add heat to a room and found the previous owner's baseboard piping had been improvised; Al replaced it properly and stayed to finish rather than book a second visit. A February 2022 no-heat call was answered on short notice, and a May 2025 customer described a replacement oil tank where the technician walked them through the controls and features afterward. The dissenting voice is a single one-and-a-half-star review from April 2021, from a customer who said they asked the company to come back and the request was ignored. Angi and HomeAdvisor both publish 4.9 from 75 ratings, which is one review set counted twice rather than two independent verdicts, and the newest written account is May 2025. For an oil boiler or furnace — especially a no-heat call in February — this is a small outfit with a five-year run of customers saying the owner arrives fast and prices fairly. Confirm the licence status with the state directly before booking, since the numbers on file come from a directory rather than a registry check.
