We've been using A1 Heating for decades and they are absolutely amazing. They are a professional company and their honesty and integrity can't be beat. They regularly clean and maintain our furnace and most recently, they replaced our hot water tank.
After they replaced it, it went out immediately and we called them and told them about it. They came back that afternoon and fixed it for us. After fixing it, they said they would be back the next morning to install a brand new one so it wouldn't go out again. They handled the situation very professionally and were back the next morning, on time, and replaced the hot water tank with a new 60 gallon tank.
I'm happy to say that we've had no issues with the new tank and they've always provided us with excellent service. They are a good, homestyle business and that is rare to come by these days. I highly recommend them!
