Jacob & his crew took great care of our immediate need, did a thorough inspection to prevent future emergencies, and explained everything perfectly. Very pleasant, efficient, & knowledgeable. Couldn't be happier with his service & his friendliness.
I highly recommend ODC HVAC! Jacob and his staff were quick to schedule and arrived right on time. I have had work done by some of the larger local and national HVAC companies in the past and I always felt they not being transparent with pricing and what my options were. I felt Jacob was honest and very helpful thinking through the options that worked best for me and my budget. Jacob is clearly an expert and is a kind human being as well!
Jacob and his staff were wonderful! Top notch service, he is extremely knowledgeable about HVAC and very thorough about checking the full life cycle of your home system. He is a skilled HVAC nerd that takes pride in his work, uses empirical data, and offers the customer clear explanations with an honest & realistic point of view. He offered us options for repair and replacement (we ended up investing in a brand new heat pump system), is very prompt, responsive, and extremely courteous. It was a great pleasure having him work on our home, and will definitely keep him as our resident HVAC expert for future projects. A gem to work with!
Jacob and his team gave us a very detailed look at the health of our HVAC system. He gave us multiple options for repairs and answered all of my questions. We’ve used the bigger companies in the past but the way don’t give the personalized service like Jacob provided. We will definitely use him again when our system needs replaced.
A+ service. Very professional, detail-oriented, and honest. Jacob evaluated my two AC units and gave me a clear, detailed breakdown of each system’s condition. He explained what was worth addressing now vs. what we should simply keep an eye on for future maintenance. Highly recommend — thank you!
Superb, caring, meticulous - the HVAC whisperer. I had first tried a local option for an issue with my geothermal system. It was misdiagnosed and would have been $5K to replace a compressor that Jacob found didn't need replacement! So glad I got a 2nd opinion from him. Identified the real issue and got it fixed, while answering all my questions. Fantastic communicator too: from prompt email/text replies, to doing a write up of his work after the job is done, to being notified about his arrival time.
Jacob came out to give me a estimate for relocating my return on a furnace. I should be writing a review on that, but he hasn't been able to do it yet because he's been back out to our house twice for emergency repairs (even on Sunday at my last minute request!) on my poorly installed furnaces. His knowledge of proper techniques and the latest HVAC technology is stellar. He has confirmed several suspicions I had about my furnaces, offering free advice on options I have to fix the things I can, and we are developing plans on fixing the things I shouldn't.
⭐⭐⭐⭐⭐ I had an issue with my AC unit blowing hot air when it should have been cooling, and OCD HVAC came out quickly to diagnose and fix the problem. Their customer service was excellent from start to finish, and they took the time to explain what was causing the issue and what needed to be done to get everything working properly again. The technicians were professional, knowledgeable, and honest throughout the process. It's refreshing to work with a company that clearly knows their trade and genuinely cares about helping their customers. My AC is back up and running perfectly, and I couldn't be happier with the service. I highly recommend OCD HVAC to anyone looking for reliable, knowledgeable HVAC professionals.
Jacob is incredibly knowledgable and prioritizes informing his clients over making sales pitches or offering subscription gimmicks. I brought him in for a consultation after feeling iffy about my usual HVAC company’s « tune-up ». WORTH EVERY PENNY. I learned so much as Jacob patiently responded to all of my questions and went above and beyond to explain things. Like a good doctor, Jacob made me feel at ease, he listened, gave me the information I needed to make future choices, and will definitely be my HVAC system’s « PCP » moving forward!
I saw OCD HVAC recommended in a neighborhood group and saw the good reviews online, so had them come out for seasonal maintenance of our units. They were very detailed, answered a lot of questions for us, and gave several recommendations to maximize the efficiency of our system and avoid future issues. We really appreciated being given the numbers to explain the recommendations. We'll be reaching back out to them with our future HVAC needs.
Call these guys first!!! I called 5 companies, 2 responded and this guy came out within 48 hrs. VERY knowledgeable, passionate about helping others and explaining the issues so you understand where your money is going. Always asks before doing work. Incredible pleasant man with a kind apprentice with him.
Super sweet and very personable! I wasn't in the position to Get what I needed yet due to my own financial constraints, but when I do I will be calling him!
Jacob was great to work with. He was detailed in his review of the analysis of the heating/cooling requirements for my older home. I really liked that he was able to break down the requirements to expected BTU's to heat the house, not just a rule of thumb or guess. He is a true professional that is very knowledgeable of codes and best practice.
Jacob installed a new Daikin ductless system in our family room and serviced our central system. The system is working great now and I have more confidence in it after Jacob identified trouble spots and put in the work to prevent future failure. On top of that, no contractor or technician has ever taken as much care to leave the work area cleaner than when they got there. Jacob puts the quality of work and customer service first and you can tell by all of the positive reviews.
Fantastic experience with Jacob! He upgraded parts of my system and explained everything very thoroughly to help me make the right decisions, did the work quickly and with minimal disruption, and provided information and quotes for possible additional changes to improve energy efficiency. I can't imagine working with anyone else for my HVAC needs.
Jacob was a genuine pleasure to work with! He explained as much as I needed, and was professional and personable. Thankfully, what I thought could be a Really Big Problem turned out to be a very little one. I have heard nightmare stories about people being taken advantage of in that situation; Jacob instead walked me through the issue, and offered a clear timeline for future things to consider as our unit ages. We are so glad to be working with him!
Jacob is great to work with and has really taken the time to help us understand our HVAC system since the purchase of our home. I appreciated that he took the time to explain the things we can do to keep our current system operating as well as outlining what a replacement system would look like. When he came in to work he was very conscientious of our schedule and making sure that the work was done well. It's always great to work with a professional who takes the time to explain what they're doing and how to take care of the equipment that is installed. Jacob went above and beyond to make sure that we understood the work that was needed and then that it was done correctly and well. We will absolutely be working with him again.
Jacob was great to work with. He explained everything, to my wife and I, from start to finish. Even though we only asked for a small fix, he gave our entire system a look over. He fixed our problem and gave us some great tips on system longevity. He is officially our HVAC guy!
Jacob did amazing work replacing our HVAC system. He spent several visits explaining what would work best for our home, and, most importantly, why. Each workday finished with a thorough review of what he did. When a few minor challenges came up, he created original and elegant solutions to adapt and improve what caused the issue. Jacob is patient, clear, always responsive, reliable...we feel grateful and secure with Jacob as our HVAC professional.
Jacob is the man! I had an emergency issue and he actually came to help me in the evening. Jacob is unique in his approach, unlike any HVAC company I’ve worked with. Very analytical and scientific explaining the logic behind the mechanics of what happens with units and does a great job breaking it down for you. He focuses on long term solutions rather than band aide solutions but will customize the solution to fit your needs and make sure you clearly understand the pros and cons. Thank you!
My wife and I had a great experience working with Jacob. He is extremely knowledgeable and gave us multiple options to fit our specific needs and budget. Jacob made the entire process easy and completed the work promptly. We will be calling on OCD HVAC anytime we need assistance with our hvac system.
Jacob was helpful and took the time to give me some guidance over the phone, even though I’m in Texas and I accidentally called him. I really appreciated it.
OCD HVAC and Jacob are the real deal. Skilled, ethical, friendly, up front about costs. We got three estimates for replacing our heat-pump. The other two companies spent a few minutes looking at when we had, wrote up a quote and were out the door. Jacob spent over an hour running a number of tests on our current equipment to determine what we actually needed, mapped the entire system and then explained everything to me. He provided me with the "Manual J report" regarding what our space actually needs for HVAC, which in my understanding is what every contractor should be doing. He and his crew spent a couple days getting the new system installed. Quiet, no mess, no problems. He showed me all that was done and walked me through how to operate the new equipment. New system cools great and I am confident that it was installed correctly. He understands HVAC, he taught it at Virginia Western, and has a passion for doing high quality work. Best choice in the region for HVAC.
We are so grateful to Jacob and OCD HVAC. As new homeowners, we felt pretty in over our heads with one of our HVAC systems failing within a few months of our purchase of a 100 year old home. Jacob took his time walking through different options and explained how we could achieve the most balanced install for increasing our energy efficiency while also considering costs and impact on the home. He’s very smart and very patient and let us ask a ton of questions. He then installed our system promptly, leaving a clean site, and made sure we understood all the things that we needed to for management/maintenance including improving our air quality. We will definitely be calling Jacob for any future needs!! He was all around fantastic.
Jacob came out the same day I needed him and was very knowledgeable and thorough. He helped diagnose my issue and was transparent in pricing. Highly recommend working with him.
Very knowledgeable and professional. We've been having issues in the past that we could not find the answer to what was happening in our house and with our unit. He thoroughly investigated our entire unit, and was able to finally explain what has been going on! He then offered various options and did not feel pushy at all. A+
We are grateful for Jacob's swift response and professional service at ODC HVAC. When our commercial property's heating system failed during sub-freezing temperatures, Jacob not only arrived promptly but also restored heat efficiently, ensuring comfort for two of our tenants. His meticulous attention to detail and dedication to customer service were evident throughout the repair process. We recommend ODC HVAC and look forward to using their services again in the future.
Jacob was able to troubleshoot my heat pump in a matter of minutes and helped me save money by figuring out that the problem wasn't what I originally thought. Honest, personable, and knowledgeable. I will be using his company for my home from here on out. Thank you!
I had a great experience with this company. Took his time and checked everything out thourly and explained everything to me in a way that I could understand. Nice change from these other large companies I have dealt with in the past. I highly recommend him.
Super knowledgeable, very prompt and helpful. Jacob is really trustworthy; I’ve had less than great experiences with others, but this guy here is the real deal. Thank you!
My installation was for a Bosch inverter split system heat pump. OCD-HVAC is currently the only authorized dealer in the Roanoke area. Jacob showed attention to detail that one might give if installing a unit at their own home. Jacob worked tirelessly with temperatures in the teens to get my home warm again. His knowledge and professional attitude were a welcomed change. Rob Chewning.
Jacob knows what he's doing. Absolutely professional, knowledgeable, and attentive! It feels good to have a local HVAC tech I can trust.
Meticulous, trustworthy, professional, caring, knowledgeable, skilled, prompt, great communication. They answer every question and genuinely want the customer to be happy. Very rare to find such great service these days. Excellent value for money. You will not be disappointed.
Jacob was great! He is professional, knowledgeable and conscientious. Great communication.
Very helpful, quickly responds, very communicative and all around honest company to work with.
Knowledgeable, trustworthy, and honestly, always on time! Thanks Jacob
Prompt and skilled service. Had my furnace up and running in no time.
Very professional and quick.
Excellent professionalism
I own a 110-year-old home in Roanoke, and I hired Jacob and his team to completely modernize the boiler/hydronic system, which we use for radiator heat in the winter and is a special perk of old-house living. It was a huge job—it took Jacob and his team three days to turn this generations-old clunky system into a 21st-century, high-efficiency system. From providing an initial overview and estimate beforehand, to managing the work flow from beginning to end, Jacob always communicated clearly and transparently with me about my options and how the work was going. (And meanwhile, even when I had an issue with one of my A/C units at the same time, he helped us diagnose and fix that as well—at no extra charge!) Jacob is friendly, reliable, and extremely knowledgable and always thorough. I very highly recommend OCD HVAC.
The OCD HVAC team did an excellent job installing my new HVAC system. They were on time, professional, and careful with my home. The installation was quick, clean, and clearly explained. The system works beautifully, and the whole experience felt easy and trustworthy. Highly recommend.
Did a fantastic job, air blows cold. Very response and pleasant to work with.

MEASUREMENT-FIRST DIAGNOSTICS
Most HVAC systems are never evaluated as a whole. Airflow, static pressure, ductwork, installation quality, system setup, and electrical protection all affect comfort, efficiency, reliability, and equipment life.
The OCD Performance Evaluation helps homeowners understand how well their system is actually performing by calculating delivered capacity and delivered efficiency — not just relying on equipment ratings or guesswork.
Based on those measurements, OCD HVAC provides clear recommendations to improve comfort, increase efficiency, reduce strain, and extend the life of the equipment.

We measure how the system performs in the home — not just what the equipment is rated to do on paper.
Comfort issues, high bills, weak airflow, noisy equipment, and uneven rooms usually have a cause. OCD HVAC evaluates the system as a whole before recommending a repair or replacement — including airflow, static pressure, temperature split, delivered BTUs, ductwork, electrical performance, refrigerant performance, and installation quality.

SERVICES
From comfort problems to careful replacements, OCD HVAC starts with measurement, system context, and clear recommendations.

INSTALLATION AND REPLACEMENT
