Appel installed our new system and we have the prepaid annual maintenance. They are great about calling and following up to keep maintenance on schedule. Techs are always very skilled and courteous. I think everyone in our Carmel neighborhood uses Appel because I always see the vans!

Have had great experiences with Appel over the last few years. Have had a new furnace and humidifier installed as well as a small A/C repair and regular maintenance. Could not recommend Appel more. Scheduling is easy and all the guys that have come out to my house for any of the services have been professional and knowledgeable.

Our Air conditioning stopped working a couple days ago. We called the company “Hope” and they came to the conclusion we needed a new evaporator coil for $5,500. Being a 5 year old system we knew this couldn’t be right. We called Appel and Matt was able to make it out the next day to look over our unit. Turns out the wireless piece wasn’t communicating properly. Our A/C is now working great. All we were charged was the service fee. Thanks a ton Appel and Matt!

I had an excellent experience with Appel Heating & Air, thanks to our service technician, Matt. He was incredibly friendly, professional, and knowledgeable from start to finish. He took the time to thoroughly inspect and clean our entire A/C system, explained everything he was doing, and pointed out a few areas that may need attention in the future without any pressure. I really appreciated how respectful, honest, and detail-oriented he was throughout the visit. By the time he was finished, our A/C was running in top-notch condition and performing better than it has in a long time. It’s clear that Matt takes pride in his work and genuinely cares about his customers. I highly recommend Appel Heating & Air for all of your HVAC needs. If you have the opportunity, be sure to ask for Matt—you’ll receive outstanding service from a technician who truly cares about doing the job right.
