"He came at 8am the next morning after my phone call and started the work immediately. He had the best price and quickest appointment for an install. Even my own gas company was booking two weeks out for our emergency- which was NO HEAT AT ALL in the winter. Jared finished the work in two days , quickly and efficiently. I will use him again for AC or water heater when they stop. My neighbor use Moulton Mechanical as well and also was happy."

"Kyle P. did all the water related services. Last year he installed a water softener tank and this year installed a sediment filter and UV tank as well as an arsenic treatment tank. He is always on time, explains work thoroughly, he's neat about his appearance and how he handles the work environment. Kyle is personable and pleasant.Highest recommendation. This company installed the ductless midi's in our home 3 years ago and in every aspect they are fantastic."

"Palmer Gas & Oil just did an entire replacement of the 20-year-old central HVAC + humidifier + thermostats two-zone system in my home with a new state-of-the-art total system and I could not be more pleased. From start to finish each employee was personable, extremely knowledgeable, very courteous, and the consummate professional. There is truth to the adage that you get what you pay for and I know I got the best. All Gold Stars!"

"Granite State Refrigeration services did an excellent job with my Mini Split install. I called the owner for a quote and he was very responsive and prompt. When at my house he explained my options based on my needs, wants and budget. He was also very knowledgeable about the products that he installs. I hired him pretty much immediately and he worked around my hectic schedule to have the unit in and running as soon as possible. I feel like a got a quality unit for a fair price and install went smooth.. I would recommend Granite State refrigeration to anyone who needs this type of service."
