SiscoTech LLC

SiscoTech LLC is a Sheffield heating and cooling company. A recent Google customer said Brian and his team installed a hybrid system of heat pumps and a furnace, used a Mass Save loan and rebates, and came out the most reasonable in both price and system design. A recent customer credited Brian, his team and office manager Marianne with thorough work completed in a timely manner. The company's website lists heating and AC repair and installation, maintenance, indoor air quality, ductless heat pumps, gas boiler installation and furnace installation. A 2023 customer said their home dates to the 1830s and that Brian spent a long time working out how to install a 5-unit mini-split system as inconspicuously as possible. A 2022 customer said the team located and installed a new furnace the day before Christmas after theirs collapsed, and that the bill was much less than expected. A 2024 customer wrote that when their boiler stopped working the night before Thanksgiving, Brian showed up within 30 minutes and fixed it. A 2024 customer said a conversion from oil to propane was done in one day and the crew cleaned up everything. A 2025 customer said Marianne and Corey helped with MassSave questions, filing the rebate and scheduling. A 2024 customer said the company was busy and scheduling took a little time, though the install day went perfectly. A 2024 customer gave a 1-star account: it "took forever to get a proposal," Brian required an upfront fee of $200, then asked for 50% of the quoted price to get on the schedule, which that customer said exceeds what Massachusetts regulations allow. That 2024 customer also said the quote kept increasing after the project was pushed into the spring.
