We called RED LINE Heating & Cooling to get an estimate for a tune-up on our heater and they gave us a good price, so we scheduled an appointment with them. Their tech came to our house and did a quick tune-up and fixed the problem but when we got the bill we were upset.
The tech quoted us DOUBLE of what they said over the phone and we called their office and asked to speak with his manager. Fortunately the manager was very understanding and gave us a refund, but it felt like they were trying to take advantage of us. Definitely make sure you get an estimate beforehand and make sure they stick with it if you choose to hire them.
