I am here again. Since fixing my air conditioning during the hottest date in July, B. Carlson has replaced my garbage disposal and there have been absolutely no problems. I signed up for the yearly service so this month Rafael Saavedra came to clean out my heater, change filters, and inspected everything. He checked the carbon monoxide level and we are good! He recommended getting a sensor and told us the best place to install the device, which we can pick up at any hardware store. I was so grateful he was not out to sell us anything we did not need (my greatest fear...lol-just a bad month for appliances). Thank you B. Carlson for taking care of your clients!
