We had a horrible smell from heating element failure. Tall Guy AC/Heat came out same day. This is so important as the breathing conditions were harsh when vents were open. They were kind and understanding and professional. They fixed our issue for great price same day. Definitely use this local company for your HVAC issues. You will not be disappointed! Can't thank them enough! read more

I received this company's info from my neighbor who told me he has used their services many times. Jacob came to check out my issue the same day I called to request service. He cleaned my system, fixed a vent that was out of place, and replaced my capacitor. The customer service was top notch. The price was reasonable. I will definitely be referring and calking for any future AC issues. read more

I been Customer of Tall Guy for over 10 yrs and have always provide a great services, price and quick response!

Tall Guys replaced my HVAC system 6 years ago, they showed up on time, communicated what they were going to do, completed the job, cleaned up and just like that we didn't die of heat stroke that summer. Few years later a capacitor went out, Jacob showed up within an hour and replaced it under warranty. This morning we had a gas valve go out, Jacob was here 25 minutes later. Replaced it at no charge because "things like this just shouldnt break"..... I was not expecting that. Not only do you not find A/C companies that stand behind their work like this, it's rare to find ANY business that provides this level of service. I've recommended them to family, friends, co-workers, even people i dont like and they all have had nothing but great things to say about Tall Guy. read more

If you need any HVAC installation or repairs done, your search is over; go with these guys. I've been using Tall Guy A/C for several projects over the years for A/C maintenance and repairs. Communication is always on point, they always show up right on time for every job, and I've never had an issue with any work they've done for me. Best of all, they are consistently the lowest price. While they've been my go-to HVAC contractors for awhile now, I had my air conditioner start to die recently, requiring a total replacement. Since it was such a big cost (over $10k), I did my due diligence again and got a handful of quotes. Yet again, Tall Guy A/C came in at the best price, and their work was impeccable. read more

Jacob was rude. Customer service skills seriously lacking. Not accommodating in anyway. Rather use someone who wants my business.

We have been using Tall Guy for over 10 years. They are very knowledgeable, honest, helpful and quick to respond. They helped me with my personal home AC, and also some clients homes. They have saved me money and also allowed me to sleep well because my AC was working.. read more

We've used Tall Guy for 10+ years, referred by a neighbor. They take care of several homes on our street! Always able to get Jacob out same day. Will use these guys for life. Always shoot you straight and provide you an honest good deal! Thanks again Jacob. read more

EXCELLENT at what they do!!! They have taken care if our home hvac for years and eventually installed two new units because ours were old and not functioning well....We LOVE the units they recommended! They have come out quickly when we needed them and are so professional, kind and REALLY good at what they do! Recently they installed 2 split systems in our 2 story work shop. Again, GREAT units cannot hardly believe how efficient they are!!! So happy we went with the split systems! All of our units are GREE. High quality and worth every penny!!! Thanks again to Tall Guys! They are the BEST!!!! read more

We've worked with Jacob twice now. The first time I requested a system evaluation because it seemed like it was running all day despite leaving the temp set to 79 degrees. He came out within a few hours with another gentleman and got right to work. They were both kind and professional. They answered my questions and explained the high summer temps were the reason for the system was running so much. They didn't charge us for this service call. The second time, I texted Jacob on a Saturday to ask if they had some time to come by as our system was running but the house was only getting hotter. He replied within a few minutes and was able to come by shortly after. Again he was kind and professional. He diagnosed the problem right away and replaced the faulty capacitor. We have been impressed with their service, promptness and overall professionalism, so we will continue to call them when we need them and recommend them to anyone! read more

Best AC company we've ever used. Recommended by a few different friends. They really know their business! Fast, fair and friendly. Will definitely use them again. read more

I've always wanted to say that I have a guy for the job. I can say that Tall Guy A/C & Heat are my HVAC guys! Jacob answered the phone and showed up and fixed our AC unit within 3 hours saving us from the 90+ degree weather. I was happy to pay for his time and the part. The "other guys" quoted us over 100x, yes one hundred times, the price of the part and labor to replace the whole system. Pro Tip: add their number to your contacts now! read more

Jeff and Jacob from Tall Guy A/C have always come in clutch when needed throughout the years. They have performed smaller repairs to get the AC running in the dog days of summer. They have also replaced an entire downstairs unit. In all cases, they have been affordable and honest. Moreover, Jacob came to the rescue during the weekend yesterday in a matters of hours. Highly recommend! read more

By far the best experience replacing an HVAC system we could have asked for. Our 20 year old system was starting to make funny, squeaky sounds when it ran and we could tell it was on its last leg. After being bombarded with companies and bids, we were told by a coworker about Tall Guys A/C. We scheduled a bid and they were in and up in the attic within minutes. No flashy presentation, no laminated posters for us, NO pushy sales pitch. Just a thorough get-to-the-point inspection. They came back with a bid that was THOUSANDS of dollars less than our "best" bid. Jeff and Jacob were straight forward with their responses and once we decided to go with them, we were on the schedule in no time flat. Luckily this all took place during "winter" so it wasn't too inconvenient to be out an HVAC system, but Tall Guys was able to help us quickly. They showed up right on time and were in and out and away within hours. A few other companies told us it would all DAY to remove and install a new HVAC system. These gentlemen are really amazing and deserve all the praise they can get. I highly recommend them! Thank you Tall Guys A/C. *they are also very tall! :-)* read more

See all

I'm a very smart and capable handy man who does excellent work. When I inevitably punched through my coolant line while nailing in baseboards and completely drained my R22 system, I admitted defeat. I called another company first that said there was nothing they could do and told me they would need to run a new line. Not liking that answer, I called Tall Guy. They came out quickly, said the repair was easy, quoted a great rate for a full system, and said they could install a few days later. They were on time, quick, and did a great job. I'm enjoying my much more efficient Rheem system! read more

Friendly, honest, straight to the point. Very happy working with Tall Guy and recommend contacting him if you have AC needs or if you're looking to work with someone who is helpful & has integrity. read more

These guys were referred to me and I'm so glad I called. Called Jacob and he come out the same day. Received a great estimate and didn't need to consider long. Scheduled and they were out and went straight to work. They installed 2 new systems. Professional install, quality product by trustworthy company. So grateful for Jacob and Jeff. If you ever need HVAC needs, please try them. You won't be sorry! read more

The service was great. He responded back quickly to my initial message and was at my house checking the issue with in three hours. Once I made a decision on what I wanted done he ordered the part I needed and was here the next day to install it. He was also very patient with me when I had questions. read more

Once again, Tall Guy came to my rescue! I cannot tell you how many times, but from homes I've owned in Austin and Georgetown, these guys are THE best! Honest, knowledgeable, reliable, reasonably-priced and kind! read more

Friday before Labor Day A/C crisis. Called home warranty and got a weak response. Tall Boy had been recommended by a friend. Called. Message was returned promptly and courteously. Jacob called back and said he was on the way. Arrived as stated. Quickly diagnosed and explained the problem. Fixed it. Told us how to recognize in the future. Great service! Great price! Will definitely use again! read more

I highly recommend Tall Guy A/C & Heat. High marks for expertise, promptness, reliability and caring concern. Jacob is amazing! He diagnosed the problem with my AC promptly, and had my AC working in no time. read more

Excellent service, very trustworthy. Thanks Jacob, you are a life saver for getting our AC running when it's over a 100 degrees outside.

Fantastic service. Came out on short notice to inspect A/C that wasn't cooling house. They identified problem with the unit. Rather than charging for the repair, they confirmed it was still under warranty and tracked down the company that originally installed the unit for me. Didn't charge anything for the service call. Would highly recommend these guys. read more

Praise the Lord for humble businesses like 'Tall Guy A/C and Heat' in Round Rock. They have been in the market for 15 years. I wish to know them earlier! They purposely kept the business small to provide reasonable prices and quality services. They came within one hour even after I left a message beyond their business hours. They fixed the AC at 30% lower price vs another bigger company came in earlier today. They also saved me from the hassle and $10k of looking into a new system during busy season Thank you so much Jacob and Jeff. read more

I've had nothing but great experiences with Tall Guy A/C. I've had a re-occurring issue with lines getting clogged. Before I discovered Tall Guy I was paying way too much, but tall guy taught me how to fix it myself by unclogging my drain. Easy. I'm also super impressed by how responsive and fast he is, he responds quickly via phone and email normally the same day, except that time it broke at night and he responded to my email the next day. Once he correctly diagnosed the problem over the phone, which resolved the issue. I don't think he even charged me. Tall Guy is fantastic, a gem, what all other AC companies should aspire to. read more

Great people, honest and responsive. Our A/C broke and Jeff came out and quickly diagnosed the issue and gave us some recommendations. We ended up choosing to replace the unit and Jeff helped us get and install a new unit within a few weeks. read more

Extremely responsive, very professional, and reasonably priced. I first heard of this company on NextDoor where local neighbors were raving about them. When my heat pump stopped working during 8 degree weather in our Feb 2021 winter storm, I tried calling a few places, including the company who installed my system. A few didnt call back (prob due to the inclement weather situation - everything is closed) and one was able to come out "sometime Thursday" (it was Monday and supposed to be freezing for the next 4-5 days). Then I remembered Tall Guy AC reviews. I looked them up, called and received a call back in a few minutes. They were able to come out the next morning at 8:30, and had things working within an hour. I definitely recommend these guys. I will be using them when I need future repairs or when it's time for a new system. read more

Called their service first thing in the morning the day our air stopped working. Jacob answered the phone personally and got my information. He scheduled me that afternoon. Came by and diagnosed the problem within 10 minutes. My system is over 15 years old and I had a feeling he was going to give me the bad news that it had to be replaced. Instead he gave me the great news that it was only a capacitor. He literally could have told me it was almost anything and I would have probably believed it and paid it. I did tell him that I believed the system was on its last legs and would probably have him come back and quote me on a new system before next summer. He literally told me the system is still pretty strong and that he wouldn't replace it yet but just continue to keep it serviced. Floored! This level of customer service is unreal these days and they will now always be my go to for AC service and repair. read more

Prompt, polite and friendly. Tried to explain how to fix it over the phone to save me the money. Showed me how to do it myself in the future. Great service and will use again. Choose these guys. read more

Every interaction and service call has been fantastic. Our old AC is on its last legs and we will definitely have Tall Guy replace it when it's time. read more

One of the best in this business! I am an active Realtor in Austin area. Jacob was incredibly knowledgable, easy to get in touch with, responded to all of my clients questions. These guys never force you into anything unreasonable. And would never sell you unnecessary service. The best people in industry! read more

They came out to service our A/C unit and also my daughter's house to see why it wasn't cooling properly. They did a great job and were absolutely fair in their prices. I highly recommend them for your next A/C jobs. They had been recommended by my previous A/C guy who closed and moved out of the area. All I can do is thank him for the great recommendation. read more

Tall Guy has serviced our units for several years now and we are truly impressed over and over again! Tall Guy is extremely professional, responsive and reasonably priced - by far the best experience we've had with any HVAC service company and highly recommend them! Jacob and Jeff have addressed various issues with our units, and every time they are top-notch with their diagnosis and service - always friendly and never pushy. They respond to our calls quickly, schedule us without delay and show up on time every time. Tall Guy bids are competitive and they are always quick to complete repairs. Too good to be true! We plan to have Tall Guy service our A/C & Heating units for many more years to come. Thank you Tall Guy! read more

Initially had an AC issue and called on a Monday morning. Jacob was quick to answer and almost as quick to make it to our house later that morning. Upon inspection I tried his recommendation but the issue was bigger than he hoped. I had to call him a few days later and he was just as responsive and helpful. He had to go pickup a fan as ours went out but he quoted it, picked it up and installed it at a fraction of what others charge. I wish I could give them 10 stars and will recommend them to anyone I know needing HVAC help. Truly the best and most honest around. read more

Our air conditioning recently went out on a Friday evening. Because of course on Friday. Their Facebook chat rep was responsive and got me onto the schedule to be seen first thing Monday morning. Another AC company had come out and told us that about $700 worth of parts would have to be replaced to even see if the condenser was working properly. The unit was 23 years old, so I figured it's time to replace it. I got the first AC company to offer a bid and asked Tall Guy to do the same thing on Monday. Within about 15 minutes of their arrival, Jacob came inside and told me he had fixed our AC unit. I was stunned and told him I thought they were just bidding a replacement. His response was that he wanted us to have AC during late July/early August and to not have to make a big decision under duress. Further, he said that he wasn't going to charge us for the repair, even if we went with another company's bid to replace the AC unit. He said just to call him and he'd come out and take his parts off, free of charge. Needless to say, I was absolutely shocked by his level of service for us, then I was pleasantly surprised by how competitive his bid was to replace our outside unit and furnace. It was significantly cheaper than the other company with a warranty that's twice as long. These guys are the best and they're the only AC company I'm going to call going forward. I highly recommend them both for their professional/competitive service as well as their dedication to their customers. read more

We have used Tall Guy A/C for years for help in limping old equipment along to the installation of a new Rheem unit several years ago. For routine maintenance to assistance in factory warranties, these guys are by far the best I have ever dealt with. I recommend often and have never had anyone tell me they were disappointed in the service they received. read more

We've used the same a/c company for a number of years and never thought to seek another...until this summer. It's been a slog - truly cruel and unusual punishment, from repair costs (including $800 in freon in May that just went, who knows where) to replacing this and replacing that....I called in another company for a total replacement when I couldn't reach Tall Guy after hours and that's on me and my lack of patience in trip digit weather...and got a quote for alot of money. I finally listened to my neighbors and called Tall Guy again. Jacob came the next morning. We got a quote that quite frankly, shocked me in a good way (my partner and I like to "guess" the cost and we were happily both wrong). He was able to get his crew in quickly. I've rolodex-ed them and hope to never have to use this Father/Son company again but if I do, they'll be my first call going forward. We appreciated their communication, speed, and overall cost. They are worth it. read more

On a hot Friday afternoon (of course) our SC stopped working properly. In less than an hour Tall Guy responded. Showed up promptly AND had it repaired! Thank you so much!! read more

I will use Tall Guy anytime I have an issue with our ac or heater. They came out quickly to give my unit a tuneup , were so polite and respectful of my sleeping baby, didn't try to sell me unnecessary services, and even installed my floater switch for me that they noticed was laying next to the unit. If you've got a problem with your ac or heat, this is who you want working on it. read more
