Other 2025 reviews mention reasonable pricing and being upfront about costs before starting work. In an October 2025 review, a customer described a positive experience getting an air conditioner installed and serviced, saying the crew was extremely punctual and they were pleased with the service. Also in October 2025, a customer said a $15,000–20,000 replacement quote from another company led them to get a second opinion from NI HVAC, with Ismael and the crew coming out to look at it.

“I had a fantastic experience with the installation and maintenance of my air conditioner. They were extremely punctual and did an excellent job. I’m very pleased with the service!”
When my 5-year-old furnace stopped working, I first contacted a large local HVAC company. They condemned the unit and quoted me $15–20K for a full replacement. A family member referred me to NI HVAC for a second opinion, and I’m so glad they did. Ismael and his team came out the same day I called and had my furnace running again within an hour. He returned the next day to correct the original installation design issue and bring the furnace and ductwork up to code—all within 48 hours of my first call. I was extremely impressed by Ismael’s honesty and professionalism. It was clear he had my family’s best interests in mind, not just a sale. The cost was very fair, and most importantly, I didn’t need a new furnace after all. I’ll continue to use NI HVAC for all my heating and cooling needs and strongly recommend them to anyone looking for trustworthy, knowledgeable, and reliable service.
