He came the next morning, fixed our problem in less than an hour we were warm and cozy. He was extremely professional, knowledgeable and very fair.

Even though, I had confirmation from them stating I had a warranty. Called State Line, they were able to find our warranty and honor it. Helped us out tremendously.

State Line Heat and Air has been a Godsend to us. They came to our home immediately when we had a…read moreproblem with a system that was not theirs and fixed it pronto. They were reasonable and could not have been nicer. We need a new system now and they will definitely get our business. They work with you in every way possible. They have put in 2 new systems in our home (it has three) and we are calling them today for the third. Thanks State Line. Becky and Richard

Seriously great company. Our heat pump went out last night on 1 of the coldest nights of the year…read moreso far (of course!). I looked up companies on Yelp Riggins had 5 stars from everyone. My husband called them at 1:57pm. They called back at 2:02pm and the heat pump was fixed by 3:26pm. He first said that they would come by tomorrow (Friday) but then he asked my husband how old he was. When he told him that he was 82 the owner, James Riggins, said he would be right over! Super nice. Super knowledgeable. And very compassionate. I would call no one else EVER. These are the people that you want to do business with over and over again. Will recommend to everyone.

Read the other reviews and thought I would give this business a try. James was just as…read moreprofessional, honest and courteous as they all said. I was looking for maintenance as it had been quite some time since any maintenance had been done on the system. James came out same day and took care of my unit for a very reasonable price. It's so hard to find good service providers, I wish he could do all my home maintenance/repairs!!

I received two separate estimates for fixing the ductwork under my 70-ish year old house. The first…read moreestimate, the person walked down the steps into my storm cellar/crawlspace, took one dark picture, told me it all needed to be replaced, and quoted me what seemed an exorbitant price. Then a family member who has used American Veteran on two homes in recent-ish years recommended them. American Veteran came out and did an EXTREMELY thorough inspection of my ENTIRE storm cellar and crawl space (seriously, they were here for I want to say close to an hour). They took a lot of pictures, measured all of my vents and my air return, and quoted me two THOUSAND dollars *less*. The first company was correct, all of the ductwork DID need to be replaced, but between the much lower estimate and the fact that American Veteran did such a thorough job of PROVING why this needed to be done meant I was obviously going with them. It was such a big job that it did take them about a day and a half to complete, but they hauled away all of the old ductwork and I could tell the difference immediately when I was able to turn my HVAC unit back on! There was one thing that they unfortunately weren't able to fix (enlarging my return) due to a sewage pipe being in the way, but this was a surprise even to the installation techs (so basically something it would have been really hard for the estimator to notice even with how thorough of a job he did). This dropped my final bill about $500, so in the end, the total cost was around $2500 less than the estimate I received from the first company. Every person from American Veteran who came out to work on my house was friendly and did their best to explain whatever they needed to/answer any questions I had. Knowing that they also did great work on two other homes for family members, I highly recommend their services, especially if you need hefty work done!
