Allegiant Mechanical Contracting INC.

Allegiant Mechanical Contracting INC serves Brooklyn as an HVAC contractor with a 4.7-star rating drawn from 14 client reviews. The business operates Monday through Thursday from 8 AM to 5 PM, with shortened Friday hours until 3 PM, and remains closed on weekends. Residents throughout Brooklyn neighborhoods can reach the team at (917) 945-4635 for heating and cooling needs. The company appears to focus on residential and light commercial equipment, with reviewers noting service calls for HVAC units, water heaters, and related mechanical systems.

The company's responsiveness stands out in reviewer accounts. Multiple customers describe Dave, the primary technician, arriving within a day of initial contact, including instances of same-day emergency service. Reviewers also note follow-through on troubleshooting, with Dave contacting manufacturers to order correct replacement parts when initial repairs did not fully resolve an issue. This level of post-service attention appears less common among area contractors, particularly for specialty equipment like commercial water heaters used in laundromat settings.

Customer scenarios from verified reviews illustrate the company's service range. One reviewer, the owner of a laundromat, describes Dave successfully repairing specialty water heaters after other technicians refused the job. Another reviewer notes Dave arrived at midnight to diagnose a power outage that had not tripped any fuses, restoring electricity within the visit. A third reviewer describes having Dave service both office and home HVAC systems, highlighting the ability to handle different property types in a single client relationship.
