Indoor Air Quality

"I absolutely love this company. For one - I had a company tell me I needed tens of thousands of dollars worth of work done, including the replacement of a water heater and I asked SNH Plumbing and Heating for a second opinion. Not only did I Not need that replacement, but I only needed a couple hundred dollars worth of service at the time. I will never use another company. They now service my furnace, water heater, central ac, and my septic. Love this company. Fair priced. Fast, quality service."
