An August 2026 Google reviewer called Best Climate Control at 8 a.m. about a faulty air conditioner; Patrick arrived by noon, found the problem and made the repair. The Sandwich business describes itself as a Cape Cod HVAC contractor, owner-operated by Dave Nelson. Its stated work includes heating and air conditioning installation, service and repair, oil burner service, oil tank replacement and Mitsubishi ductless mini-split systems. The company also identifies itself as a Mitsubishi Preferred Diamond Contractor. A customer writing in October 2025 described a boiler replacement after their existing boiler stopped working. Dave came out an hour after the call and gave an estimate several thousand dollars below the customer’s oil company. Best Climate Control then arrived on time to replace the boiler a few days later. The customer praised the crew’s professionalism and kindness, while noting that they lived in the same town as the business and could not speak to scheduling flexibility in other towns. In a November 2025 Google review, another customer described Pat as punctual, friendly and knowledgeable about their heating system. A December 2023 reviewer likewise praised the company for showing up when promised. Google’s August 2026 listing showed a 5-star average from nine ratings.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Best Climate Control. Use it to sanity-check bids, then get the real number in writing.
Estimated range
$5,000 – $11,400

Called at 8am for a faulty a/c unit. A wonderful tech named Patrick was able to get there by noon. He found the issue and repair was made. Great service.
Truly the Best heat and ac specialists around. Pat was on time ,friendly and knowledgeable about my heat system. I will recommend them to everyone ✔️
Our water boiler stopped working this week. The quote for a new boiler from our oil company was insanely expensive and they told me they couldn’t fit us in for a week or two unless I put down 50% right then and there. My fiancé is working overseas so I was very stressed out trying to make a decision and my future in-laws recommended I try Best Climate Control. I couldn’t be more relieved they did! Dave came out an hour after I called and gave me an estimate that was *several thousand* dollars less than the oil company’s. They then showed up right on time to replace my boiler just a few days later. They were professional and kind, and they certainly gained a loyal customer. I can’t recommend them enough! I will note: We live in the same town as Dave’s business. I’m not sure if they could have the same level of flexibility with customers in other towns, but I can definitely speak to their professionalism, punctuality, and kindness. Thank you, Dave and co.!
Best Climate Control is excellent! They are professional, honest, and show up when they say they will. I cannot recommend them enough!!! I'm so happy that I finally found a reputable company!
