Customer Reviews

Masoud Asgari

I had a great experience with Volta Heating, Air Conditioning & Appliances. I initially received a very large estimate from another company for an issue with my heating/A/C system, so I asked Volta for a second opinion. Their team was extremely professional, knowledgeable, and honest. They carefully evaluated the situation and provided clear, expert advice rather than pushing unnecessary repairs. Thanks to their integrity and expertise, I avoided a major unnecessary expense and saved a significant amount of money. It is rare to find a company that combines technical expertise with such strong ethics and transparency. I truly appreciate their honesty and professionalism. Thank you, Volta! I highly recommend them to anyone looking for reliable and trustworthy HVAC, heating, and air-conditioning services.

James was great! We were having issues with our furnace/HVAC unit. We contacted multiple companies that either did not know the issue or were charging thousands. James from VOLTA was friendly, professional, and quickly identified a fix for much cheap! Highly recommend!

James came out and was very courteous and professional. He fixed my refrigerator in a short span of time and was very polite throughout the service call. I would definitely recommend Volta services to friends.

I can see why this company gets good reviews. When our washer went down, I looked up every appliance repair shop in our area. I read reviews, but at the end of the day, I went with the one that responded repeatedly and in a timely fashion. Volta and James, consistently let me know when they could come out, and then when they were on the way. I had looked up the repair on YouTube and I could do it, but it would take quite a while as it required the inner/outer door to be removed to access the latch and then take the other side apart to access the lock. I showed James the washer and let him get to work. About 45 minutes (or less) he let me know the repair was done, using our current parts and that they warranted the work. Very nice guy and he knew exactly what he was doing. I can't say enough about this team. Definitely recommend.
