Full Spectrum Services is a heating and cooling company in Bellingham, MA, hired for furnace repair and replacement, AC repair and installation, and heat pump and mini split work. A recent customer says Philip responded to a request for a heater replacement quote with an in-home assessment and a detailed estimate the same day. Another recent customer says the company installed their AC units and services both the air conditioner and furnace twice a year. A customer who accidentally shut off the pilot on their heating system says Keith arrived the next afternoon and got the system running again, and a property manager with 15 properties says Eric arrived within 24 hours when a tenant's furnace was not heating properly, diagnosed the issue and got the heating system working again. In a 2026 review, a customer said the company installed a new heater system, removed the old heating unit, fixed a damaged duct in the attic and put in a new digital thermostat. In a 2025 review, a customer described a Mitsubishi mini split and heat pump installation finished in just over two days in a house with no basement. In another 2025 review, a customer said another company had come out twice to fix their air conditioning, and Keith found a faulty part, replaced it and got the AC running smoothly again. A separate 2025 review describes an old oil furnace replaced in one day by four technicians.

Philip, Bentley, and Keith were fantastic. The office staff at Full Spectrum Services were always responsive and helpful with every step. The whole team was very customer focused, and that showed in every call, email, and visit. Philip quickly responded to my request for a heater replacement quote with an in-home assessment and a detailed estimate the same day, just hours after meeting with me. He gave me more than one repair and system replacement option and took extra time to answer all of my questions over several days by email. His replies were clear and useful, and he even included product details and supporting information so I could better understand the heating equipment, efficiency ratings, and thermostat choices. Their pricing was very competitive compared with other heating service providers. We had a unique setup that needed a few special accommodations, but the team made sure our needs were fully handled without any hassle. The heater installation was completed on the day promised, the work was professional, and everything was cleaned up when the job was finished. Bentley carefully explained the new heating system technology and helped set up the thermostat app, which made the system easy to use right away. Philip was also on site during the full installation, which gave us added confidence that everything would be done properly. We are very pleased with the results and would highly recommend them to anyone needing heater repair, replacement, or other heating services in Bellingham.
They installed our AC units and have been servicing both the air conditioner and furnace twice a year. They are always thorough, professional, and complete the HVAC work at a fair price. Recently, our technician Eric serviced our AC during very hot weather in Bellingham. He went above and beyond to provide excellent AC repair and maintenance, and he left our whole heating and cooling system running like new. We really appreciate his hard work, especially his courtesy, professionalism, and attention to detail. I highly recommend them to anyone who needs a new AC system, seasonal HVAC maintenance, or an emergency air conditioning repair service call.
We had gone several days without heat during a very cold stretch, and we were having a hard time finding a fair heater repair contractor to help. Then we found Full Spectrum Services online and sent a message. Philip got back to us the same day and came out the next day to inspect our heating system and furnace setup in Bellingham. He explained the problem clearly, gave us a fair price, and was very helpful about arranging a payment plan after the initial down payment. That made the whole heater repair and furnace replacement process much less stressful for our household. Another company we contacted was not nearly as flexible or helpful. Philip returned that same week and, even with a few unexpected issues in the system, completed the new furnace installation in a timely way. He was professional, polite, and honest throughout the entire job. He also made sure the heat was working properly before leaving and answered our questions about the system. We highly recommend them for heater repair, furnace service, and related heating work, and we would gladly use their services again.
Our furnace kept shutting off, and replacing one part at a time was getting expensive. We called Full Spectrum Services, and they explained that with our heater being over twenty years old, it would likely keep failing piece by piece until the whole system was replaced. They recommended installing a new furnace, and the heater repair and replacement work was done so well that we also had the air conditioning unit replaced. After that, we decided to have the water heater changed too. It was not quite as old, but it was packed with debris and sediment. Jalen and Keith tried multiple ways to drain it, but it was still extremely heavy and difficult to remove from the basement. They handled the whole job with real skill and effort, and they even managed to work without upsetting our three dogs. They really went above and beyond by also correcting a faulty filter system and removing an old failed humidifier setup tied to the heating system. Now we feel confident about our heat, air, and hot water for a long time. Great service, knowledgeable workers, and excellent furnace expertise. Hire them and you will not regret it.
look no further for furnace repair and heating service from full spectrum services. jalen and the crew are the go-to team. they handled a clean, professional furnace and heating system upgrade, including dual-zone heat for the home, and the whole job turned out great. there were a few small issues along the way, but jalen responded right away and got everything corrected fast. partway through the project, i also asked to add another heating-related upgrade, and the team made it happen without any trouble. the workmanship, finish, and overall service were top quality, and the system has been running smoothly in bellingham.
