I had an issue with my Rheem furnace not heating, so I reached out to HVAC-group for assistance. The technician was quick to identify the problem as a faulty flame sensor. The service was prompt, efficient, and ultimately effective. I'm very pleased with their work and would highly recommend their services to anyone facing HVAC issues.

Yuri is a true professional and is a very knowledgeable expert about furnaces.I called him for advice when another well known Hvac company wrongly diagnosed my Trane furnace blower noise and told me I needed to undergo a $1500 repair. Yuri quickly assessed the problem and voila no more blower motor problems. All for $140!!Thank you Yuri! I highly recommend your service, honesty and expertise.
