Came out late and prompt. Throughly went through my furnace after questar thought I might have a leaky gas valve. Called Action which I will never use ever again, action said the same thing but didn't even really inspect it or trouble shoot it. Just went off the opinion of Questar gas. Then action quickly wrote me a quote for 750 dollars. Called Jyst Right Air who throughly went through everything and tested and sniffed with meter for any gas leaks. They said they found nothing and did not think there was anything wrong. Never use action!!!! They install stuff wrong and then when they are paid to come out and diagnose an issue or possible issue, they don't even do that and just rely on a gas company who do. It install or work in furnaces. Absolutely terrible. I will only use just right air from now on!!
