Verified record
Southern New Hampshire HVAC Services LLC is a Windham heating and cooling company offering HVAC installation, heating, air conditioning, and oil-tank services. Its website says it serves Derry, Londonderry, Windham, and Manchester and offers free estimates. A recent Google reviewer praised Brian's yearly maintenance on two air conditioners and two gas furnaces, describing him as professional, friendly, and thorough; the reviewer also said he found and replaced a damaged heating-system part before it became an emergency. Google shows five stars from one rating. Before booking, confirm the technician, scope, and any parts included in the estimate. A New Hampshire HVAC license appears in the state-registry material, but the holder of record is Southern New Hampshire Plumbing, Heating, Cooling, LLC rather than this exact business name, so ask the company to clarify how that license applies. This looks suited to homeowners seeking heating and air-conditioning maintenance or repair in Southern New Hampshire. Confirm licensing responsibility, the written estimate, and emergency availability before work begins.
Brian was great! He cleaned and performed yearly maintenance on two AC's and two gas furnaces. He was professional, friendly, and thorough, explaining everything he was doing. He even found and replaced a damaged part in our heating system which saved us from needing an emergency down the road. I highly recommend Brian and SNH HVAC Services.
