Excellent

There’s no better than X-TREME. Had my furnace serviced/cleaned today and I can honestly say the technicians were fantastic! They did a great job and explained to me in detail when I had a question. This is my third year doing my annual furnace cleaning I had other companies in the past but they didn’t compare. So glad found X-TREME

Turned the system on, there was an error code of roll out open. Found the limit on the exhaust tripped. Reset and the inducer turned on and fired properly. Cycled several times. High winds can push the exhaust down the flue and possibly trigger it after shut down.

24-hour Emergency Heating Repair: Responded to a late-night emergency call after the client reported that their boiler had stopped producing heat. Arrived on-site and established safe working conditions, then inspected the boiler system to identify the issue. Found a faulty ignition module preventing the burner from firing. Replaced the defective component, tested the boiler through multiple heating cycles, and verified proper operation of all safety controls. The emergency repair was successful, and the boiler is now fully operational, restoring heat during critical hours.

Ductwork Repairs: Arrived at the client’s home after they reported weak airflow in several rooms. Inspected the duct system and found multiple holes and separated seams in the supply ducting, causing significant air loss. Cleaned the affected sections, sealed the holes with mastic and reinforced tape, and repaired the loose connections. Tested airflow afterward and verified strong, consistent delivery throughout the home.
