After the storm we experienced here in Lake Charles we thought that we would be without heat for quite some time luckily we were referred to Eric and he came out that same day, gave us a quote and came back two days later and finished the job, snow still on the ground and temps still freezing. We cannot say how thankful we are to have him be in charge of fixing our heating system.

I will definitely be using Greiner for any future AC/heating needs! Eric was great. He was very professional and answered all my questions. He was straightforward in telling me what I needed and what I could expect. I never once felt like he was trying to sell me a service or product that I didn't need. It's great to find someone that really enjoys their work and wants to give quality service!
