Reviews of local pros in Roselle, Illinois

Victor at GNV was amazing to work with. He was extremely knowledgeable and really helped put our minds at ease with replacing both our furnace and central air conditioning units this year. They also provided excellent service with cleaning and sanitizing our homes ducts and vents. I would highly recommend GNV.

Great service. AC stopped working on 90° day. They showed up in an hour, had it fixed in 30 minutes. Knowledgeable and friendly guys at a good price. They explained every step of the way and figured out the issue immediately. Would highly recommend

I will recommend them hands down. I call them last night and they were willing to come out on a drop of a dime. Technician was prompt and knowledgeable. He diagnosed the issue got the part and I was up and running. He took the time to explain the process and answered all my questions. If your looking for a great company that cares call them. Trust me you won't regret it.

I had to replace my furnace - two techs came and did an awesome job the next day. I would recommend GNV Heating & Aur Conditioning and already have.

Great company, they were very responsive and informative. Will have them back out to do my annual maintenance

I had an incredible experience with GNV Heating & Air Conditioning, and its owner. Over the past few years, they've replaced my AC unit, dishwasher, and water heater, and I couldn't be happier with their work. The owner was consistently responsive to my emergency calls, which put me at ease right away.

One moment that really stood out was when I called Victor with a question about turning on the pilot of my old water heater. Instead of trying to sell me a service or push for a call-out, he simply walked me through the steps over the phone. It was clear he genuinely cared about helping, which is so rare these days.

Every service visit was professional, timely, and respectful of my home. I would highly recommend this business to anyone in need of reliable and customer-centered service. It’s clear they go above and beyond for their customers!

Best company for heating and AC repairs, maintenance and replacement, I use them for my business and house. Very reliable and responsable. Don’t risk your investment with other cheap options.

Outstanding work! I Had both my furnace and AC replaced at the same time. The technicians were here on time, explained everything thoroughly, put down drop cloths throughout the house and cleaned up everything when they were completed. The sheet metal work, plumbing and attention to detail is flawless. Highly recommended! Thank you GNV!

Victor and team are very reliable. Responded quickly and efficiently. Replaced my furnace at a fair price. I’m very satisfied with the job performance and professional character of the team. I recommend GNV for your furnace and A/C needs.

Came out with a free estimate and cover many details some other missed from wiring changes needed for the thermostat, updated refrigerant and associated equipment as well as whether or not shifting to high efficiency was the right answer. Very thorough.

The install took one day with polite and respectful team of 3 . They got right to work and maintained professionalism all day while also being very down to earth and willing to explain everything.

Installed furnace , air conditioning unit, humidifier, and water heater .

Fantastic work and worth the money. They will be my go-to for hvac work at my residence.

Same day water heater replacement, job finished maybe 3 hours from my initial call. Fast service, clean workers and great price!

I’ve used GNV for maintenance and repairs, and they’re always reliable and do solid work. I always recommended them to friends and family!

Victor is always very responsive and works hard to take care of our heating and cooling concerns as quickly as possible. Additional staff is also friendly and efficient.

My AC went out. I contacted GNV and made a same day appointment. Each time I've called they have been at my home fixing the problem within 1 hour even on Saturday. They are quick and professional, explained my options and proceed with the repair. This company is top notch and provides the highest quality customer service. Will be using there guys for all future calls.

I have a service contract. The tech (Josh) came on time, did the work, and was on his way. He checked everything out, changed the furnace filter and was very pleasant to work with. 5 stars for today.
