Full Spectrum Services

I've had Full Spectrum Services come to my home a few times for HVAC repairs over the years, and recently it was finally time to replace my old furnace after it lasted more than two decades. The whole experience was excellent from start to finish. There was no pushy sales talk—just honest advice about what would work best for my heating system, with clear explanations about the options and what would come next. Elias and Raymond, who installed the new furnace, showed up right on time, were very professional, and you could really tell they cared about doing a quality job. I'm very pleased with my new furnace and glad I chose this company for the installation.

full spectrum services is a truly professional company. when our heater stopped working in the middle of winter in northborough, their technician elias arrived at our home within an hour of our call. after a complete diagnostic, elias explained that we needed a new heating system and immediately brought over portable heaters so we could stay comfortable. he was very knowledgeable about our setup and walked us through every step, including filling out paperwork for masssave rebates and providing information about financing options. elias did his best to speed up the delivery of our new heater, and the team was back the very next day after it arrived. all the necessary work was scheduled in advance and everyone showed up right on time. our old system was removed and a new one installed quick

I got three quotes for heater repair, and Full Spectrum Services offered the best value with top-quality equipment. Their quote was clear and detailed, listing everything that was included. The only thing not covered was the copper pipes. The technicians, Raymond and Elias, were quick, reliable, and did exactly what they promised. They took the time to explain how my new thermostat and heating system worked and made sure I knew I could call if I had any more questions. I’m very happy with their work and will definitely use them again for any future heater repair or HVAC needs.

As first-time homeowners, we weren’t sure what to expect when our heater started making a loud clicking sound. We decided to reach out to Full Spectrum Services for help. After sending a quick email on a Sunday, Elias gave us a call within a couple of hours and scheduled a technician to come out at a time that fit our busy schedule. There was a reasonable fee for after-hours service, but it was worth it since we couldn’t be home during the day. Raymond, the technician, arrived on time and was extremely helpful. He patiently explained that the noise was due to a dirty part inside our furnace and reassured us that our heater still had many years of life left. We really appreciated that he took the time to educate us about how to keep the furnace running smoothly, without trying to sell us an
