Shout out to One Hour Heating and Air Conditioning in San Ramon. I called them for a rental property in Danville, and they promptly came out and addressed the situation with my heater. They gave me a few different options with no high-pressure sales tactics. After choosing the best option for my budget, they had it up and running the same day. I wouldn't hesitate to recommend them for any heating or air conditioning problems.
