“Story is much too long - basically, washer stopped working properly.I attempted to have 2 other companies repair, no luck.Reached out to Volta late morning today (Sat). Was able to have technician show up w/in 90 mins (wow!)Dave is a godsend!! Listened to what my issues were, then got right to work. Took less than an hour to assess, diagnose & resolve the multiple issues!!!I have a working washer again! I should have called Volta first! I highly recommend this company.Thank you Dave/Volta ? “

“James did a great job updating and rerouting my dryer duct. He responded very promptly, came on time, was friendly and polite and there were no hidden or added costs.“

“We had still an original almost 50 year old furnace when we moved into our new house. My husband and I took a few years to decide on what kind of new heating/cooling system we wanted to install in our house. I interviewed many different companies. Maybe 6-7. Austin from Comfy Heating was extremely knowledgable about heat pumps. He was very straightforward with his recommendation and didn't give many details, compared to other high rated companies. My husband and I had many questions for him about the efficiency of heat pumps, and Austin got every detail right. At the same time he was offering us a very competitive price. Also the install team was knowledgable. They had one worker less than expected on the day of the install, which resulted in a very long work day for the two workers showing up. They were not able to finish up with everything. After the install we encountered some problems with air leaking out between the heat pump and the ducts than we would have expected. My husband didn't agree with the approach of just putting some tape on the wooden box, and wanted the root of the problem to be fixed, which meant to take the blower out of the heat pump, and insulating the unit with the sheet metal box properly. Comfy heating had to come back a couple of times until the problem was really fixed. And now we have a super efficient heat pump with minimal air leakage. Comfy heating did absolutely a GREAT job in leaving us with an excellent install.“

“Andrew with Adrium is a true professional. I initially contacted him via Thumbtack along with 2 other business late at night to get the process going. He replied early the next day and I was fortunate in that he could come by to diagnose the problem with my broken GE double oven that same day. He checked the error code and did some testing and went back to his office to review the necessary parts he would order. He gave me a game plan of ordering some extra parts in case there were multiple problems and said he would only use the necessary parts and charge labor based on what was used. He is prompt, professional and clear about what he'll be doing. I will definitely use Adrium again if I have problems with other appliances in my home.“
