Bob Heinmiller replaced our AC system, they did a great job. The team was professional, clean and caring towards our house, they made sure to test everything before leaving to make sure it was working correctly. We have a zoning system that can be tricky sometimes but they got it right with no issues. Pat, Bobby, Levi & Rohan were all very professional, knowledgeable and friendly from start to finish of the job. I highly recommend Bob Heinmiller for any AC replacement.

Tyler was hands down the most professional and courteous service technician we have ever had. Not just in the a/c category but ever! He took the time to explain what the issue was and options we had to fix it. He was super knowledgeable but also has the ability to explain issues clearly to a non professional. Every step of the process our family felt that Tyler had our best interest in mind. He was so kind and has an authentic and natural hospitality that isn't seen much.

$437 for a Saturday call out!
$230 weekend fee
$207 for 20 minutes - shop vac sufficiently clean drain....GO ELSEWHERE....that's a crazy price but I'm gone all next week so I had to bite it. After using BOB Heinmiller for years...never again. Nice tech.

Matthew visited our home in response to my request for an evaluation installing a house generator. The entire process from initial contact to a finished operating system was a pleasure. Amanda and Debbie handling phone calls and coordinating Seminole County inspections were outstanding, friendly, and informative. Mark, Joe, and Dan completed the installation in one day with little invasion to my landscape. If you can utilize any service or products from this company I would highly recommend them without question.

Used them previously twice before and was great. Unfortunately this past service I will never them again. Had a clear leak in the evaporator coil and asked the technician if its worth putting in coolant based on the severity of the leak. He explained he was not sure (the reason I called him out). He then added refrigerant to our system, which lasted only 24 hours and come to find out was pretty dangerous and not approved by the EPA. Called back and told the lady the issue I had over the previous service and she said he added refrigerant, which is environmentally safe. All in all, waste

I just had the very best experience with Bob Heinmiller Air Conditioning. It was only 4 days from the time I called their office to request someone to quote a new AC System, until it was installed and running. I was surprisingly pleased with the value they offered. Patrick was responsible from the start to the finish, Bobby and Anthony did a fantastic job with the installation. I really don't know what more I could say. I am a customer for life.

Our business AC went out on Thursday in the middle of summer. We called and spoke to Patrick about a replacement AC system. They had a great price, service and was the only company who could get a new unit as fast as they did. My staff and me our very happy with cold AC again!
