Pay 1 price for yearly service for air and heating. Best price, very clean and knowledgeable. One price for two visits a year.

After trying maning different heating and cooling companies, I've finally settled on one that stands head and shoulders above the rest - Appel Heating and Air Conditioning. They're honest, reliable, and don't try to sell me things I don't need. They were the only company my mother would use, and I should have listened to her earlier and saved myself a lot of heartache from less-than-honest competitors. I don't even bother to call anyone else anymore. Highly recommend!

I had an HVAC system installed last year. It was very hot that day and they told me that they did not want to test furnace after the installation at that time but are going to do so when it gets cooler. Now when I called to schedule a visit they told me they don't do it.

Another great job by Appel! David, the technician got my 83 year old Moms furnace back up and running just in time for the mid-March snow and cold snap. He was very professional, kind and considerate. I highly recommend Appel.....locally owned and operated, which is important to us!
