About NOVA Green Energy LLC
NOVA Green Energy LLC operates as a Virginia Class A Contractor headquartered in Falls Church, serving the greater northern Virginia metropolitan area including Annandale, as well as portions of Washington DC and Maryland. The company holds Master Gas Fitter, Master LPG Gas Fitter, Master Mechanical, and Residential Building Energy Analyst endorsements from the State of Virginia. With 175 reviews earning a 4.9-star rating, the contractor has established itself as a go-to specialist for gas fireplace installation and repair throughout the region. The business also maintains National Fireplace Institute certification as a gas fireplace specialist and RESNET HERS Associate credentials for residential energy analysis.
What distinguishes NOVA Green Energy from general HVAC contractors is their narrow focus on gas fireplace expertise combined with comprehensive energy auditing capabilities. The company operates as a certified gas fireplace specialist, offering both installation and specialized service work that many broader HVAC companies delegate to subcontractors. Their Virginia Class A licensing enables them to handle complex gas line work in-house rather than coordinating multiple trades, and their RESNET certification allows them to conduct whole-house energy audits that inform heating and cooling recommendations. This combination of specialized fireplace credentials with broader home energy analysis creates a differentiated service offering focused on both comfort and efficiency.
Reviewers consistently highlight the responsiveness that keeps this contractor busy. Laura McGeary described calling in the morning and having her fireplace fixed by afternoon, with the technician arriving with the necessary part already on his truck. Arun Janakiraman experienced similar same-day service when Mike told him the repair could be completed that afternoon. Grace Marasigan scheduled online and received a next-day visit from Delio, who thoroughly explained fireplace maintenance procedures while keeping her living space clean. Syz Rip noted the company arrived the same day and completed the repair in 30 minutes, contrasting their speed with competitors quoting twice the price with 1-3 month wait times.
What Customers Say
175 reviewers awarded a 4.9-star average rating, with multiple customers specifically mentioning same-day service and technicians arriving with parts already on their trucks. The single 1-star review cited communication issues during project planning rather than service quality.
