See Why We’re the Top Choice for HVAC Services

in West Volusia County

We have used Jacob Heating & Air Conditioning for a long time and have been very satisfied with their service. So when we needed to replace a central air unit that had developed a leak in the outside condenser, it was an easy choice to stick with what had worked. The unit was 23 years old, and it just didn’t make sense to pay the $2,300 repair cost for a unit that had outlived its life expectancy. So, in with the new! We agreed on a replacement unit with Alex on Monday. Alex was excellent in explaining the various choices available to meet our needs. He is very knowledgeable and was excellent at explaining the different manufacturers and equipment available. Rather than push us into the highest priced unit, he suggested a very good model that matched the features we needed, and a price that made sense. Much to my surprise, the install date was just three days after our consultation. Sure beats waiting around! They totally were able to accommodate us at a time we were available. Today, Thursday morning, the installation crew of John and Bryan arrived promptly at 8:15 am as promised. These two technicians were fantastic! Not only were they punctual and extremely skilled at what they do, but they were very personal and I was really impressed at how well they worked together as one excellent team! The installation was on the second floor of our home, in a utility room surrounded by rooms with white carpet. By trade I am an engineer, and I tend to be fairly particular as to quality of work and skills displayed to get things done. These two guys were unbelievable! By 3:30 they were done. The install was meticulously performed and there was no evidence that anyone had been in our home! All old materials were hauled away, and nothing showed that a major job had been done. Both John and Bryan were not only excellent workers, but also great at explaining all the things I needed to know about our new HVAC unit. I can’t say enough good things about them, and recommend them both and their Company Jacob Heating and air conditioning to anyone needing this type of service. Thanks to all involved!
Response from the owner:Thank you, Klaus, for your wonderful review! We're glad to hear that you had such a positive experience with Alex, John, and Bryan. It's great to know that the installation went smoothly and met your expectations. We truly appreciate your recommendation and look forward to serving you again in the future!

Phillip, Larry and Bryson did a super job ininstalling our new ac/heater. They came early and worked continuously until it was completed. And, cleaned up afterwards. We have been with Jacob for 14years. May 14, 2026 and November 12, 2026, Areli came and serviced our AC/HEATER Unit. He did a fantastic job.
Response from the owner:Thank you, Karen! We truly appreciate your kind words about Areli. Thank you for your loyalty!
