just moved to los angeles a few months ago and didn't know anyone for recommendations. found la heating and cooling pros llc online and took a chance. from the first call to the finished frozen coil fix, everything was smooth. they showed up when they said they would. explained what they were doing without being condescending about it. stuck around to make sure it actually worked. cleaned up after themselves before they left. it's hard to find that level of service when you're new to an area. glad i found them.
