If you want quality, responsive service at a fair price call Nashoba Air. Our air handler stopped working last night and I reached out to Nashoba after—hours. Though I am a first-time customer the company owner Shawn Kelly callled me personally and said his people would be in touch 730 AM next day (he did offer to fix that night but I declined). 730 am the phone rang and my scheduled service tech Brian arrived on -time several hours later. Brian was informative, thorough and gave us a very fair price to fix the problem. Shawn and Kerry Kelly who own this company give back to the communities of Westford and Littleton and run a good business. I will Be a repeat customer
