Landen did a great job performing maintenance on my AC/heating unit. Very professional and answered all my questions, highly recommend him. Thank you.
I joined the maintenance plan with iron shield and I’ll tell you what buddy these guys know what they’re doing the most professional and easy-going company I’ve ever had to deal with the technician. Landon did an incredible job and was nothing but professional. From the notifications of who your technician is, and when they’re showing up to, when they show up in the cleanest service van I’ve ever seen to the technician getting out looking professional to a T with a smile on his face and a great attitude . PLUS YOU CANT BEAT THEIR PRICES ABSOLUTELY INCREDIBLE COMPANY CAN’T WAIT TO DO BUSINESS WITH THEM FOR A LONG TIME
I had an excellent experience with this company from start to finish. The communication was clear, honest, and professional, and they took the time to explain everything without any pressure. The AC unit they recommended was exactly right for my space, and the installation was smooth, clean, and on schedule. You can really tell they care about quality work and customer satisfaction. It’s rare to find a company that’s this reliable and easy to work with. I highly recommend them to anyone
Landon did a great job with our furnace maintenance. He was polite and finished the job in a timely manner. He explained ways to improve our heating and cooling.
We had our semiannual maintenance service done today by Landen. He was very professional and courteous. He explained everything in detail. Thank you!!
Landen was very thorough and told us things about proper maintenance the homeowner should do that we’ve never been told. Did a walk through that’s never been done and suggested a surge suppressor for protecting the a/c unit for minimal cost that no one ever suggested and a better and easier filter system as the one on the air handler has always been a pain to get out…that no one has ever suggested. What a professional! Great job Landen.
Iron Shield technician (Landon) was superb. He was friendly, courteous and professional. He had come to replace a leak in a gas line, discovered a crack in the regulator which was subsequently replaced by him as well. Great service, fantastic young man, a credit to your company
Iron shield heating and air is a great AC service in Ocala. I used them this past year for my maintenance and they are always very professional and thorough. Landon did a great job at explaining the state of my AC and recommended to us multiple options to resolve the issue.
We had Iron Shield come to are home and check ducts for leaks.
We had them replaced in 2024,and the company i hired totally did a terrible job.
Iron Shields technician showed me the mistakes the other company made,and explained how they can fix it properly.
Landon the technician was very helpful with explaining the process they will make to correct the mess the other company made.
I highly recommend Iron Shied .

Landon from Iron Shield inspected and serviced my HVAC unit. He arrived on time, was very professional, and took the time to explain everything he did. I was extremely satisfied with his work and highly recommend Iron Shield.
My hvac unit had an issue today, I called the office and explained the issue. That was 8:15 this morning, I had a tech at my house by 11am. My tech had the issue resolved within the hour. Thank you to Landen my tech, very polite, and absolutely professional in every way. If I have another issue with my unit I will absolutely ask for the some tech.
Landen was very efficient and showed me what he did to my units. Great mannerism and cleaned everything in the units

I was having an issue with my heating in my home. I called Iron Shield to see how soon they would be able to get someone out to work on the unit. Cindy in the office had Jesse on his way the next day !! I had to be away from the house at the scheduled time and I called Jesse to let him know. Not a problem they just bumped me back a couple hours. Nice to have a company that is willing to work with their customers!! When Jesse got there to check out the unit we had a real stumper on our hands. Pressures were strange and things weren’t acting quite right. Jesse called his tech support and soon they were on scene with us. Meticulously and thoroughly Jesse and Andrew eliminated possibly problems. After about 4 1/2 hours the guys determined what they thought was the problem being very careful not to misdiagnose it. The time and dedication they took to make sure we got it right was impressive to say the least. Can’t thank these guys and the company enough for all their help! First rate company with first rate people who know their stuff !!

Crystal, thank you so much for taking the time to leave us a review pertaining your AC repair. We appreciate customers like you!
Impeccable service! Can’t say enough good things! We had our AC system replaced a couple of years ago by a different company and after two years of problems, we reached out to Iron Shield. They came out right away, immediately identified the problems and gave us a fair and reasonable quote to correct all our issues. Everyone we dealt with was very professional and courteous. They arrived within the time frame given, with text and emails to let us know they were on their way. Would 1000% recommend them to all my friends and family.

My blower motor went out last summer during the work week. I didn't have time to shop around and ended up paying $980 for a replacement. That wouldnt he so bad, except when it was installed i said there was barely any air flow coming from the vents. The motor installed is clearly the cheapest one they could find and isnt really buying me time for a total unit replacement since my electric bill is way higher than it should be. For that price i expected a variable speed, but got a really crappy single speed that barely puts out air. After the install was done he said my condenser coil was dirty. I've never had service that didn't include coil cleaning and to say that like he didn't just have the unit open and could have taken care of it blew my mind. Today the fan motor started making noise so i went to check it out. That's when i noticed all the missing screws. I had the unit taken apart for the blower motor install and all screws were together so they could be replaced but today i found several discarded screws around the unit. Next time i need service I'll just take the time off work, buy the parts, and do it myself. Had the coil been cleaned and all screws replaced I wouldn't even be writing this review, I was going to let it go. But this is ridiculous. I definitely wont be calling this company when I'm ready to replace the unit. Which will be quicker than anticipated due to the very low quality $980 motor.

The most professional HVAC company I’ve ever worked with!!! The install team kept us informed about everything they were doing. The entire experience far exceeded our expectations!!!
Iron Shield Heating&Air Provided prompt service and was very informative. They got our air conditioner working right away!🙂 I would definitely recommend them.
He showed up on time and fixed the problem fast. I would recommend this company to anyone
I had an excellent experience with Iron Shield Heating & Air! Andrew quoted a fair price on Monday, and by Tuesday afternoon, my new AC unit was installed—quick and hassle-free! From start to finish, their team was professional, knowledgeable, and prompt. The technicians arrived on time, answered all of my questions, and completed the installation smoothly. The work was top-notch, and they made sure everything was running perfectly before they left. I also really appreciated that they left the area spotless. I highly recommend their services and would definitely refer them when you need a reliable company to keep your house cool!
Iron shield heating and air have done it again!!! Another amazing job they have done for me. Incredible prompt service and the crew always exceeds my expectations. No excuses just great results.
I am pleased with the outcome of the service call today. The staff was very nice, the tech was on time and very knowledgeable. He diagnosed my problems, gave me two ways that it could be corrected. I was not pressured into buying a new system at this time, and was given a military discount which helped a little. Thanks to the entire staff.
Jesse and Andrew were awesome! They got my AC & heat working perfectly. It's a new home and was installed incorrectly. They fixed it all. This photo was what it was like before they fixed it.
I Would like to say this company is one of the best companies I have worked with. Iron Shield Heating and Air are very professional with a great family feel. My daughter was the one who called them because they had installed a new unit in the house where I live. I had problems with the heat not working and they were called and immediately sent a very kind and knowledgeable Tech out. He spent a great deal of time checking and also calling the company which made me feel comfortable as while they were on the phone I could hear the other person on the phone, and part of the conversation was they could not get the part until the next day. He asked the person on the phone should he keep it hooked up working like it was since he had already done the work and diagnosis but needed a new replacement part. I heard the gentleman say yes keep it at least running the way it was as it was going to get very cold tonight so he made sure he kept me with heat and said he would be back first thing in the morning. Well he sure was back the next morning and with him was the other person who had been on the phone call. I not only received great service but feel like I made new friends who could be trusted. I have worked with many companies from electrical to construction and find this company is worth the great reviews on this page. We cannot make everyone happy all the time but after having been in a business that you have those you will never make happy these reviews say a lot about Iron Shield Heating and their employees. I am sorry to say I forgot his name but I believe it was Bob who came out and what a fantastic reliable and friendly person. Thanks Iron Shield!!!
Denise.
