First and foremost: THIS LOCATION IS A LIE, THESE PEOPLE ARE BASED IN ONTARIO. There is no business at this location and this is effectively an ad for a call center that will connect you with a business from somewhere else: All Pro Plumbing and Heating from Ontario. All Pro wanted $90 just to come out and look. When they saw our unit was 50+ years old they basically said they had no way of fixing it and it would be too difficult to find parts for the valves, etc. Then they tried telling us it would be $14,000 for their “entry-level” replacement A/C which is just laughable. We called someone else who was able to patch up our old A/C unit and fix leaks in the copper piping for around $1200 despite its age.
