These guys are real professionals! My 80s house had the original duct system (which has poor airflow to the extra rooms at the South end of the house where it's warmest) and 15 year old condenser and air handler which was weakening. I was suplimenting this with window units for a few years. Jacob's designed a replacement trunk for my house using manualJ specification (seriously don't consider any other duct system) and replaced my dying AC system, new condenser I wanted in the backyard so had Freedom Electric install a new electrical box at the new site ahead of time. Jacob's ran new lines in the attic and now the old one on the side is hauled away! I requested modifications to the original proposal including adding active filtered return vents to each bedroom, filtering the original return vent in the living room, and added surge protectors to safeguard the new equipment. The new trunk system with the modifications I wanted was a little more expensive but completely worth it. The new system was already good but it was apparent too much air flow was going to the North side where needed the least, to fix this I requested they add a damper to the duct going to the master bedroom on the North end which is next to the air handler. We cut about 75% of the air pressure going to the master bedroom which helped close the gap in temperature difference between North and South sides (from about 5 F in the afternoon to 1 F :) . I'm a analytical person and tend to ask a lot of questions and tend to annoy people whose answer is usually One of my biggest peeves is when "experts" refuse to answer the why of any question and merely assert to be experts. This team demonstrated their experience and knowledge to me very clearly and provided acceptable reasoning to each answer. All my initial doubts were put to rest and they worked with me without any argument when I brought up the pressure distribution issue I noticed after the initial install. These people tolerated my inquisitiveness and helped me through the process to figure out solutions to all the problems I wanted to resolve with the old system. The professional attitudes were very consistent from sales down to the installation team and the manager who came out later to inspect the work. I couldn't ask for a better experience! I want to stress that I do not fault them for the original 5 degree variance but appreciate how quick they were to resolve the complaint and implement a low-cost solution without making a fuss. Usually fixing one problematic system results in other existing problems more apparent. This house needs new insulation and vinyl windows but I just can't afford it now. The HVAC overhaul was the first major step to updating this house. Now I'm confident the house will be comfortable all over. Good by window units! read more

These guys are great! It was a noval happening to actually have someone show up when they said they would. Keegan, Bryan and Pablo were a joy to have in our home. They were friendly and nice to talk to while all the time being very professional. They were always cleaning up after themselves and made sure everything was done properly. They replaced our whole system and worked until the job was finished. We would definitely recommend them to others. Thanks for a job well done! read more

Pablo and Bryan did an exceptional job ion the installation of our Mitsubishi Mini-Split. They are courteous, professional and knowledgeable... we highly recommend them and this company! This is our second A/C purchase from Jacob's Heating and Air... read more

Be careful using this company. They have great techs but poor customer service (Accounting/ service manager). They will give you poor pricing when trying to renew your service contract. When you question them on the pricing not adding up, they will drop you as a customer. read more

Ray is a great guy, very professional. Gets things checked and explains everything. Excellent service

Our experience with Jacob Air Conditioning was excellent. we had all new duct work installed. Pablo, John, JD, and Keegan were always here on time, went right to work and cleaned up afterwards which we appreciated. They explained what they were doing and made sure that the air flowed in the direction that we wanted for each room. The men were very friendly and considerate. We will definitely continue using Jacob Air for all of our heating and air conditioning requirements. Mary & Phil Kremer read more

John and Keegan were on time and professional. Alex gave me an estimate Tuesday and the system was installed the next day. From the very pleasant office staff (Debbie and Penny) to the installation it was a professional and painless experience. read more

Areli (and a second man I did not get his name) came out and fixed our air conditioning problem and recommended a future project to make our A/C work even better. I have used Jacob's for several years, for several issues and they are always on time, provide an estimate of work and always solves the problem. Their technicians have always been knowledgeable, helpful and communicate well. read more

My central air conditioning finally stopped after 19 years. John, Keegan and Alex were exemplary in getting me a new unit, and installing it. They were professional, courteous, answered all questions and made the transition effortless. They put in a window air conditioner to keep me comfortable while I waited only a day for delivery of the new system. I have been using Jacob Heating and Air for maintenance for many years. I trust them implicitly. read more

We've used them twice and both times were emergency repairs. Excellent in all categories.

Our first experience in Florida with this company. Very impressed a young man named Adrian was so polite and arrived on time. He was most responsible during this pandemic ugh...spending time to clean coils and everything. I used to be in the industry and sold "what keeps you cool - refrigerants" He was very professional - spent about 1 hour. No extra charges for anything unusual. Overall we had a great experience and look forward to being a long term customer! read more

On time. Efficient. Clean. Friendly. Both JD and Paglo (sorry, this might be a misspell) installed a whole new system just before the storm. We've used Jacob's Heating & A/C for years and will not switch to anyone else no matter the price. They are professional and a joy to work with!! Thank you so much!

Extraordinary company to do business with!! From our first phone call to set up an appointment for an estimate on a new A/C system to completion of the installation, everyone involved was pleasant, informative, and competent and professional. The office ladies, Penny and Debbie, answered our questions, called us back, and were always cheerful. Robert Jacob was so personable when he came to check out our needs. He listened to our concerns, and gave us much helpful information so that we could decide on what A/C system and accessories we would need. He promptly sent estimates for four different options, and then revised them further as we considered our choices. On the day of installation, four technicians arrived promptly and each one got to work to get everything going smoothly. John, Devon, Bryson and Roy were considerate of each other as they took out the old unit, moved the old air handler and compressor and worked to upgrade our air return size and worked quickly and efficiently. It was a Very hot day, but we heard no complaints and they worked steadily til all was done. We couldn't be happier with the entire company employees and our new A/C unit!! So much quieter, and will most likely lower our electric bill!! Thank you to ALL!! This company has been in business for 102 years, same family and can be trusted to do it right at a fair price!!

Horrible people to do business with. They were the original installers of my AC unit so I called them about my unit going out. I spoke to their Manager and he told me that they could replace my current setup (variable speed) to a single speed unit for a lot cheaper than replacing the old motor. So I setup a time for them to come out and replace the unit and the guy come out and said he couldn't do it and they still are trying to charge me a fee for them coming out and doing absolutely nothing. When I called to ask about this charge they sent me in the mail I was told that the manager would call me back but he never did they just sent me another bill in the mail... Stay away from this company they just want to take your money. read more

We just had new duct work and air conditioning system installed. They were met with some challenges, but the team (John, Jason, Chris & Roy) handled things calmly & professionally. We highly recommend Jacob Heating & Air Conditioning. read more

Robert Jacob's company did a fantastic job. He made sure everything was done correctly. The installers (John and Alex) did a professional job and left the home immaculate. Penny (office) was easy to work with to discuss permits, scheduling, payment, et cetera. Highly recommended. Thank you! read more

Never again. Last week terrible heat. Worse experience dealing with this company. It's all about the money for them. As they try to put up a good front, been around forever, blah, blah, blah Long time DeLand resident. I will never contact them again. read more

I have used this company since I moved to Deltona some 9 years ago. They seemed to be on their game for the most part, however all that changed when they installed a new 6k ac unit for my upstairs. To look at the duct work and electrical you would be impressed, as I was, but it has turned into a nightmare. I have mold growing out of my ducts, around my attic opening and around my attic fan opening. They have have been to my house over a dozen times and have just made the problem worse. The owner, Robert, even came out and made some suggestions, which made things worse. Several valve changes, compressor change, filter upgrade, duct cleaning, bleaching, register sealing, blocking off my attic fan, new insulation around stair opening and still the problem persists. It is to the point now we find it hard to sleep upstairs. I have been VERY patient this whole time as they seem like good people, but honestly I do not think they know what to do. Oh and now the system is out of warranty. I have spoken with other ac companies, mold remediation experts and duct cleaning folks and they all point to the way the system was installed, maybe to big or too small, not enough return, the list goes on.....Does anyone know a GOOD ac company? read more
