I was hearing a rattling at night in our HVAC system that's in our attic. Didn't want it to be something big so I sent him a message through yelp and he was able to come out 3 days later (messaged on a Saturday he came out Tuesday since Monday was a holiday). My heater and everything still worked just fine, so it wasn't necessary for him to come out quickly.
When he came out, he couldn't find anything wrong, since the noise only happened at night, so most likely a resonance vibration. He was looking for anything wrong and said our unit was working smoothly.
He also informed us of things other companies will try to sell to you that aren't necessary, like a furnace cleaning which isn't needed for natural gas. He also took a look at our water heater and gave us a rough quote for the future. Also informed us that it's not necessary, and actually worse, to flush your water heater system. Our water heater is 13 years old and he said to just fair until it breaks, instead of trying to sell us to replace it after informing us he replaces his every 5 years so his expensive hobbies don't get flooded in his garage.
Still after all that, no charge for just coming out! Safe to say we'll be calling him in May for an AC tune up (he also said a furnace tune up is not necessary in Vegas) and any future plumbing and HVAC needs.
So please give him a call! I'm a huge small business supporter and Luis is awesome! The 64 5 star reviews are legit.
