HVAC reviews in Dallas, North Carolina

We've had an exceptional experience with David and his team at David and Goliath HVAC. From our initial conversation to the final completion of the job, the process was seamless and stress-free.

They provided a thorough inspection and estimate within 24 hours, and followed up to answer any questions we had about the scope of work. We needed ductwork replaced under our nearly 100-year-old home, which had limited crawl space – a challenging task. After meeting with David and reviewing their quote, it was clear they were the right team for the job.

Although the job wasn't for the faint of heart, David and his team were outstanding. Over the two-day project, they were punctual, kept us updated, and cleaned up as they worked. David went above and beyond to ensure the job was completed on time and with the utmost care.

We can't recommend David and Goliath HVAC highly enough. They're an honest, reputable, and thorough company that delivers exceptional service. We'll use them for all our future HVAC needs and highly recommend them to anyone seeking a trustworthy HVAC company.

We left a message on a Saturday night and David got back with us within 45 min and was able to come out the next morning to fix our AC. This was good because everyone else we called were going to take DAYS to come out. Quick service and the price seemed very fair and reasonable. Very very grateful for this hard working man! Would recommend him 1000 times over!

David did outstanding installing our new system. He arrived at the time he scheduled and completed the install and made certain that we were satisfied with the service. He took time to show us the operation of the thermostat and it features. He also was very reasonable on the pricing. I would highly recommend David!

Yesterday my house was not cooling. I arrived home from work to find my house was at 80 degrees when my thermostate was set to 70. I called David and Goliath HVAC because of the amazing reviews! They answered my call promptly and were very professional and knowledgable. They said they would be here within 30-45 minutes. They arrived exactly within that window. As soon as the team arrived I walked outside and was greeted. They Immediatly got to work. They walked me threw exactly what my issues were and what there plan was to try and fix them. they didnt mind me standing over there shoulder (yes i'm that guy) as he walked me threw everything and ask me anytime he was planning on doing anything that involved disassembly. He didn't Try to make me buy any extra stuff. he told me what it could use (preventitive maintance) and didnt force me to do anything, and wasn't trying to upsale me. This company is top notch and Definitly live up to the 5 star rating. They have great pricing and are super clean and careful in everything they do. I WILL BE GOING WITH DAVID AND GOLIATH HVAC anytime I have anymore Hvac issues. But at this rate I wont have for a real long time thanks to them! Now im sitting back enjoying my 70 degree house with my 3 Dogs and I. Thank you!

Best ac repair company in the area!!! David is professional, on time and knows his craft. I have known David a few years now and I can say without a doubt, David and Goliath heating and cooling is the company to call. he works tirelessly, to get the job done and leaves you with great results. He has showed up for me the next day many times, worked hard, provided his findings and fixed them. Just a great man to deal with 100% trust in his craft, and I am proud to say I would call David every time. I am just happy to know that David and Goliath heating and cooling is there for me when I need help the most.

I called last night at 7:20 and this guy actually answered the phone! That alone deserves 5 stars. I told him the issue I was having with a mini split that my guy and I installed ourselves a few months ago and he actually apologized that he couldn't get to me till 9 this morning because he had just gotten home from working. 😂 I was expecting days in the heat so 9 am the following day is completely acceptable and understandable.
He sent me a txt to let me know when he was on his way this morning too.
He got here and we talked about what was going on, he looked at the unit and all the lines (because I had 0 pressure and an obvious leak), gave me an estimate and asked if it was acceptable. After I told him yes, he went to work. He cut ac lines, re-flared the copper tubing to stop the leak, pulled a vacuum, and refilled my ac unit.
His price was right in line with what I expected to pay and he was super friendly. After talking with him I found out that he's a 1 guy operation that does most everything by himself.
He saved my number in his phone so that when I call him again, he'll know who it is which is pretty cool too because we know most companies don't care enough to know you by name.
I will definitely be calling him again if I have any further issues and when I need maintenance on my ac unit.
Excellent job! Thank you so much!

I manage EZStore n lock in Dallas. Our owner likes to use local smaller companies. David came out and took care of our AC problems. He was on time and got our AC fixed quickly and at an affordable rate. I also liked that he was very respectful. Highly recommend.

David was extremely responsive and knowledgeable! He was transparent with pricing and notably more cost effective than other companies! David was able to come next day and gave me a discount for multiple units. You need to call him next time you are looking for anything heating and cooling. You won’t find a more honest, hard working, and over all better business.

David has been to my house twice … once for a maint issue and another for a system check and cleaning. Friendly, efficient and did a great job answering my questions. Very happy with his service and he will definitely be my new ‘go-to’ guy.

Woke up to no heat. Called before 7am and received an immediate response along with them quickly coming out and getting my heat fixed at reasonable price. I will use in future and recommend to family and friends as the service was phenomenal.

David was prompt, helpful, and extremely efficient. He had our AC up and running quickly and explained exactly what was going on so we can prevent it from happening again. Highly recommend their services for anyone needing fast, professional HVAC work!

Amazing work from an amazing company! He responded to every question I had no matter how small it was. I am a huge supporter of smaller local businesses and the amazing work and awesome price I got from this company just continues to prove these local companies have the big guys beat every time. They were very respectful and kind, hopefully I don't have anymore large jobs come up soon but I will now always go back to this company for any and all HVAC services.

I had a great experience with David & Goliath’s HVAC services. David was quick to respond and immediately identified the issue. Not only did he fix the problem, but he also took the time to show me what was wrong and explained how I could resolve it myself if it ever happened again. That kind of honesty and customer care is rare these days. I would definitely use David & Goliath’s services again and highly recommend them!

Our furnace needed to be replaced. I had called three companies prior for quotes and they were all very high. David & Goliath hvac was recommended to me so I gave them a call. I am so glad I did. They were so much cheaper and so easy and great to work with. The owner is absolutely amazing guy. They go above and beyond to make sure everything is the way it needs to be. Very knowledgeable about codes and systems.

I was referred to David by a high school friend and reached out to him for help with my AC unit. David responded quickly and came out with his partner, Marco, to diagnose the issue. They identified and repaired the problem efficiently. David was extremely professional, respectful to my family, and took the time to explain everything clearly throughout the process. I truly appreciate the excellent service and the knowledge he shared. I highly recommend David and his team for any HVAC needs.

David is an incredible young man with integrity! He has honest and fair pricing. He came out and helped us in a pinch with the recent snowstorm. Our HVAC had frozen due to the fan motor dying, and it couldn't defrost itself. He had the part in his van and proceeded with the repair with my approval. He never tried to upsale me anything. Choose this guy for your HVAC needs!
