Coldfire Mechanical LLC is a heating and cooling company. A 2026 customer who called about their thermostats said they came out the next day and within a couple of hours had all the thermostats working and rewired to work properly. That 2026 customer said Mike also noticed another issue on the boiler and fixed it, and called the bill more than reasonable for the time Mike was there. A 2024 reviewer wrote that they installed central AC, a new heating system and ductless units in the upstairs of the home. That 2024 reviewer said they told the customer the process and how long it would take, sent pictures with daily updates, and finished within the time they said. A 2024 customer said they had been at the house for both water and heat. A 2020 reviewer said they had used Coldfire's services for around two years and that every quote was fulfilled on the scheduled time.
I called Coldfire for an issue with my thermostats after nest stopped supporting the first generation thermostat. They came out the next day and within a couple hours had all my thermostats working and rewired to work properly. The bill was more than reasonable for the amount of time Mike was there. He also noticed another issue on my boiler and fixed that. Great company!!!
