    I highly recommend Hartzell's Heat & Air. I called and I got an appointment the same day, I mean that hardly ever happens. Ace, well he's your guy, professional, helpful, friendly, courteous, knowledgeable. Yep just downright great service and affordable to.

    Called their office around 2 pm and had a very nice interaction with them. Honest and up front with pricing. I think it’s scary to pay a trip fee and get a loser for a technician… we got a great outcome. The risk was worth the reward! They had a tech there by 4 ish and went right to work. When Jose was in the attic he noticed the carbon monoxide pipe leading out from the heat wasn’t done right and was alarmed that someone could be affected by this. We looked and could see someone had done their job wrong previously. We will have them back to do that repair and anything else related to their field. Fantastic company and customer service!

    I was very pleased with the work of Hartzell. Their techs(Jose, Tim and not sure of the 3rd techs name) were very friendly and helpful in getting my entire unit (inside/outside) installed. Tim also took the time to explain and show me how to work the new installed thermostat. Jose, did the walk around with my husband before heading out. Shelby, the office personnel was also very helpful in every way; explaining what needed to be done as far as repairs vs replacing. All in all my experience with this company has been nothing but great.
