Lisa Chen

Hackensack, NJ • 2 weeks ago

Excellent experience with 551 HVAC. They were quick to respond and got my new furnace installed at a reasonable price and ahead of schedule. After a nightmare experience with another Bergen County company, these guys were a breath of fresh air. Professional, knowledgeable, and no surprise fees.

The crew from 551 HVAC was absolutely fantastic to work with. Always picked up my calls or got back to me within minutes. No confusing technical jargon - just straightforward talk about what needed to be done in our home. Such a pleasure dealing with contractors who actually communicate well!

551 HVAC really saved the day when our heating system died during the coldest week of the year - with my very pregnant wife about to pop! Their emergency service in Bergen County is the real deal - had heat flowing again within hours. Now that's the kind of service you remember and tell your neighbors about.

Sarah Miller

Fort Lee, NJ • 2 months ago

Called 551 HVAC when our central AC shut down on a 95-degree afternoon. The technician arrived on time, diagnosed the faulty capacitor in 10 minutes, and had replacement parts right in his van. Honest, fast, and very reasonably priced.
