Nashoba Air used to be the best around. Not so much now though. The business model and prices have obviously changed. Very overpriced now and the tech that came to the house really pushed to sell things that were unnecessary. I had a minor leak in my compressor and their recommendation was to replace the 5 year old unit which they sold me. They charged me over a hundred dollars a pound for refrigerant that cost six dollars a pound to buy. For what I ended up paying, I could have just gone and bought the necessary equipment and done the work myself. This is the literal truth, I priced out all the equipment. It’s HVAC, not rocket science! Feel a kinda swindled. Definitely will look elsewhere or just repair myself.
