CRS Mechanical LLC

Oil-to-gas conversions are among the home projects customers describe hiring CRS Mechanical for. A June 2026 Google reviewer said Kason and his team converted the home's oil system to gas with a new boiler, explained both systems, and were upfront about pricing. A May 2026 Reddit commenter separately recommended CRS Mechanical out of Concord after an oil-to-gas conversion that included a new boiler. CRS Mechanical says it handles heating, cooling, boilers, chillers, gas fitting, and commercial refrigeration for homes and businesses across central New Hampshire. Its stated service area includes Concord, Laconia, Meredith, and Tilton. New Hampshire licence GF1407546 was registry-verified active in August 2026, with Kason L Sabean as the holder of record. HomeAdvisor describes that number as a gas-fitter trade licence. Recent home-service accounts also describe repair and maintenance. A July 2026 customer said Justin and his assistant assessed an air-conditioning problem, kept the household informed, and got the system running again. Another July customer praised a thorough HVAC service visit at home. A third described Kason as candid about pricing and the product. Repeat installation work appears in a March 2025 review. That homeowner described hiring Kason and his crew for a mini-split in 2023, another in a renovated addition in 2024, and a high-efficiency gas furnace in February 2025. An August 2025 customer said CRS replaced an old furnace and air conditioner with a Bosch system after several competitive quotes, at a price substantially below the larger companies' quotes. These are the customers' comparisons, rather than a published price guarantee. A January 2025 reviewer described a no-heat emergency involving frozen pipes. The customer said Kason returned the message within minutes and explained a solution the customer could carry out independently. Another January 2025 homeowner said the crew moved its schedule around to install a replacement furnace the next day. Commercial customers describe refrigeration and troubleshooting work alongside the home projects. A July 2026 reviewer called CRS their regular choice for commercial freezer and refrigerator repairs. In November 2024, a catering-business customer described a walk-in freezer problem: Kason investigated on Wednesday, provided an estimate that day, and the installation followed on Friday. An April 2025 healthcare-facility reviewer said the team diagnosed a problem that had remained unresolved for more than four years over two days, then resolved it a couple of hours later.
