What Our Customers Say


"So fast! I called them as soon as our air conditioner failed (pretty easy to tell by the burning smell), and they booked me only a couple of hours later. The house hadn’t even finished losing heat before they had the AC up and running again. Great price for such fast service, too!" - Angela N. Meyers


"I chose Accuserv to handle the installation of my new air conditioner, and I received great service throughout. They were courteous and friendly both on the phone and in my house. They started on time and finished more quickly than I expected. The bill they gave me when the service was complete matched what I was estimated, and was more than fair for the work." - Gregory Anders


"Very prompt service on a hot water heater repair. The repair was scheduled for the day after I called, early enough that I was going to be able to get in a hot shower before I left for work. The repairs involved a part replacement that they were able to handle on the spot. That took a little less than half an hour, and everything worked perfectly after." - Aleks Kubilius
