“We have used A-1 in several of our homes from full AC/Furnace unit install for the entire home to repairs and more. From Boise/Meridian up to McCall, we have always had a great experience. This most recent job, Randy and his team have been especially amazing. Incredible communication, on time each appointment, install was professional and so quick.

A-1 Heating and Air ALWAYS provides great service to their customers! I have had A-1 service my furnace and air conditioner for 20 years. The service person was on time and professional. I highly recommend A-1Heating to anyone looking for great service and professional service employees!

My only issue with A-1 is they offer a program to service your AC and Furnace with two visits. The problem is that by the time they finally come out for the AC visit, it is late summer and about to cool weather. Sloppy business model to say the least.

I am sad to have to write this. I have used this company for quite a few years. my hvac system finally gave up and needed to be replaced, these where my first guys to call and have been for a while. the tech was great. when it got to the sales person it was such a bad experience I will never use this company ever again. its a shame because I though they had some good techs but there sales person Danny completely ruined my experience with the company. never again. bad sales people ruin businesses.

Technician showed up same day I called the office about the problem, and was professional, diagnosed the issue quickly, and had the part on his truck to get me up and running again within an hour or so. I use A-1 for furnace service annually, so maybe that helped in their responsiveness, but regardless, I do really appreciate having them care enough to get someone out same day to get my AC system diagnosed and back operational. Highly recommend!

A-1 was excellent from start to finish. I woke up on a Monday morning to an 85 degree house, and called A-1. They scheduled me as quick as they could and had the whole system fixed within a couple of hours. The technician was extremely professional, provided an explanation for everything he did, and sought to find the "best" option as opposed to the "easy" one. Overall, his due diligence saved me money as he was able to repair my system with one part, as opposed to a more in depth repair or replacement. I would recommend A-1 to family and friends, and plan to use them in the future for my HVAC and/or electrical needs.

A1 Heating and Air came out to replace our business’s AC unit after it went out. They were very professional, very speedy with a difficult replacement of an old system, and got us the best deal! Would recommend them to anyone!
