8/31/2026 Ken and Erick took care of my routine maintenance and did an excellent job. They were efficient, polite and got the job done. I have been a customer of Jacob for several years and have been happy with their service. I also tell my friends to use Jacob for their AC needs. JD and Pablo were excellent. They came as scheduled. They were professional and polite. They replaced my compressor and it is cooling down my home.

This review is long overdue because I don't work well with computers or the internet, so I had to corral my husband to have him to type this up for me. I'll start with "I trust Jacob Heating & Air Conditioning with all of my air conditioning needs". About 3 years ago, I had another AC company servicing my unit. They were the original installers of the unit back when my house was built in 2005. They were Ok for a while, then they decided to change the terms of my maintenance contract from 2 visits per year to 1 visit after I had already purchased it. I fought with them over the 2nd visit that I had prepaid and they basic told me, "Too bad!" We used that company for 8 years and they decided it would be better to dump me than provide service. I did not renew my maintenance contract but had to have them out to take a look at my compressor because my fan was not running. I figured it had to do with a condenser as had already happened twice before. This time though, the repair technician said my AC unit was bad and that they could install a new unit for just north of $20,000. I kindly said no and solicited help from the DeLand Neighbors FB page. Out of about 60 responses, 54 of them recommended Jacobs so I gave them a call. Turns out the technician, Ken, lives right across the street from my house. Ken reviewed my system, said it was in good shape, and did not have to be replaced, but did need a condenser. I purchased an annual maintenance contract with Jacob and Ken replaced my condenser. After one visit, I was convinced that this was the kind of business I wanted to support. A business highly recommended by the community, with excellent technicians, and fair pricing, you cannot do better than that! If you need an AC & Heating "partner", Call Jacob Heating and Air Conditioning FIRST! You will not be disappointed. Sorry, this took so long to post. Thank you, Ken and Jacob Heating & Air Conditioning, for your commitment to treating your customers fairly and with respect!
Response from the owner:Thank you, Elayne, for your wonderful review! We're grateful for your trust in Jacob Heating & Air Conditioning and thrilled to hear about your positive experience with Ken. Your feedback means a lot to us, and we appreciate your support in the community.
