FMS Mechanical Solutions

FMS Mechanical Solutions operates as a licensed HVAC contractor maintaining a perfect 5-star rating across 18 client reviews in Chicago. The team provides heating system repair, air conditioning service, water heater installation, and gas line work for residential homes and apartment buildings. Technicians Gustavo and Joaquin lead service calls throughout Chicago neighborhoods, responding to emergency requests with next-morning or same-day appointments. The company also handles plumbing-related tasks, distinguishing them from narrow HVAC-only contractors.

What distinguishes this contractor is their commitment to emergency responsiveness, a homeowner reported Gustavo personally answered a late-evoring call after the gas company disconnected a water heater due to carbon monoxide detection. The team tackles complex installations including nonstandard water heater replacements and multi-level gas line routing from basements to upper floors. Reviewers consistently note technicians explain what needs to be done before starting work, ensuring homeowners understand the repair process and associated costs.

Customer stories reveal the breadth of their experience. One reviewer discovered Gustavo arrived the morning after an emergency call following a gas company shutoff, completing the water heater reconnection after a chimney sweep cleared the flue pipe. Another client called regarding a loudly malfunctioning heater, and Gustavo along with Joaquin resolved the noise issue. Luisa Santoyo's furnace installation showcased the team's thorough approach, explicitly explaining each step and answering questions throughout the process.
