Had a tenants furnace go out on a Friday late afternoon. Our other furnace guy couldn't get out there until the following week. Called A-1 & they had a guy out there that evening installing a furnace so my tenant had heat. They went back on Monday to finalize the install. They were so pleasant to talk to. I didn't feel like I was bothering someone on a Friday night. Ben followed up w/ us a couple of times that evening & again on Monday. He even sent a follow up card in the mail. Excellent customer service. Yes, the price was a bit more expensive than another guy, but knowing that they were there for us, the customer service was top notch and the reliability we had was well worth the money! Knowing someone has your back when you most need it is money well spent! Definitely our go to HVAC!
