HVAC reviews in Dallas, North Carolina

David is awesome! Love supporting local business and he is located right here in Dallas. Answered my call and was at my house within 30 mins. AC back up and running just 2 hours later. Very kind and passionate about what he does! Would 10/10 recommend him to anybody!

Let me start off by saying I had bad experiences with several companies; like them not showing up and then being overcharged. I’m glad I found David and gave him a chance. He was professional, worked in a timely manner and he answered my inquiry pretty quickly. He was very thorough and made sure everything was working properly before he left. For this reason he has earned a costumer for life! Good job David!! A++

David is an exceptionally knowledgeable young man in his field. He’s always upping his game to be the best in the industry and not only to outsmart his competitors but to outwork them as well. As a home inspector, I am a generalist in many areas. But when I need expertise on HVAC, I always give David a call or text for advice and tips. I know David personally as well, and can speak for his truly outstanding character. Should you ever find yourself in need of heating or cooling service do not hesitate to call David and Goliath, You will not regret it!!

This is why I love small businesses! David went above and above for my family. This summer was rough for our neighborhood, and he knew how to truly diagnose our issue and fixed it right away. We did incur another issue, and he came out within 2 hours to address it. It was beyond his control and a manufacturer issue, but he still addressed what he could until our warranty people could come out and fix the issue. Thank you so much, David. See you when it's time for our maintenance service.

David was on time, super personable and trouble shot our issue saving us so much money. He has our issue fixed in an hour for such a reasonable fee. We had another company come out earlier in the week before I found David and they clearly were trying taking advantage of our lack of hvac knowledge. David was honest and professional. I'm so thankful I found him! Highly, highly recommend.

I highly recommend David for HVAC care and maintenance. After seeing all the great reviews online , I got in touch with him and he came out the next day. he was here for a good hour , cleaning and tuning everything up and also changing the filter. In addition, he was very personable, knowledgeable, and on time. The price was also reasonable. I will continue to use him in the future. Cheaper and better service than those large heating and air companies.

David did a wonderful job
He was punctual, efficient, and most important
Honest

David was punctual, friendly, and knowledgeable about his work. He explained what needed to be replaced and why, which was very helpful and important to me. He did an excellent job cleaning out my hvac unit and getting it in great shape again! He did an awesome job for a fair price! We'll definitely call David & Goliath HVAC for our future heating and cooling needs. Thanks again!

After reading all of the amazing reviews here, I called David & Goliath HVAC. David answered the phone! Then he went out of his way to drive almost an hour to my house on a Monday morning when my AC went out. There are just not enough great words in the English language to describe the service I received! David is one of the good guys. He is passionate about his craft. He cares about people. He researches product to ensure he is using the best quality parts. And he is fair and honest in his pricing. If he’ll have me, I’ll be a customer for life!!! Thanks so much for what you do, David! We need more like you!

Delayed review - I cannot say enough about this young man! It was 6/25/2024 about noon when I noticed the house was getting very warm and humid. Sure enough, the A/C had frozen up. High temps were expected to be in the upper 90's that day and they were! I scheduled an appointment on-line with David & Goliath about 1:30 that day for the following day. I received a call immediately and he said that he could come out that day. He saved us from staying in a hotel that evening. He did and an amazing job getting our A/C up and running! He was honest, fair, reasonable, professional and personable. I highly recommend this company.

Amazing job! Had a competitor out to repair some bathroom ventilation in attic, but they could not complete the task of my dryer exhaust installation & were going to have to come back with a new quote.
Got a second opinion from D&G who came out within 20 minutes after calling!!! He was able to complete the job the next day at nearly half the cost of the other guys!! Sooo glad I called! His work was quick but thorough! Very pleased

I called and he immediately got back with me. He showed up very promptly the same day and was extremely courteous. I did not feel like I was being taken advantage of, and I trusted his opinion as to what we needed done. I was given a reasonable quote. I would recommend.

David was great, he arrived within an hour of me calling. He was polite and courteous the whole time. Not once did I feel him use scare tactics or up charges like the bigger companies. He exuded the small business personal charm that I've come to miss in this world of huge companies. The service was excellent and at a good price, I'll definitely be calling him for all my A/C needs.

David’s the best! Quick, professional, and detail-oriented — best HVAC service in all of CLT, hands-down 😊.

Called David on a Saturday about our AC not working properly. He called back within 30 minutes to discuss possible issues as well as set up a time for the next day. He came right on time and immediately got to work diagnosing the issue and giving a very fair price to fix. He went above and beyond for us and he made sure we were informed of everything he was going to change. I was so impressed that we're definitely making David and Goliath our main HVAC company.

David is hands down one of the nicest, honest and knowledgeable in this profession. I reached out to him for a 3rd opinion on an issue with the HVAC in our house. It wasn't working properly because of a rusted evaporator coil. The other companies that came out were going to charge me just as much to replace the coil as it would to have an entire new system installed (8k-15k). David prompty responded to my request within minutes and communicated with me to understand the full issue. He did not charge me a service visit but prior to ordering the part he stopped by to check everything over. Within a day he was back and installing the new coil. He cleaned out the ducts as well and filled my refrigerant. I should mention that one company added a pound of refrigerant a week prior and now it was empty. I highly recommend David and Goliath HVAC and will be using his company going forward for all maintenance as well as if any issues should occur. This man saved me thousands of dollars just before Christmas and has now made it possible for my family visiting will be comfortable. Thank you David and Nathan for providing amazing work today and for your stellar care for the customer.

Our a/c quit blowing out air last night. After calling a few companies this morning to get someone out to fix it today and finding their service charges astronomical, we called one more company, and it was David and Goliath. David had an affordable service charge and could come out within a very reasonable time. David did a thorough evaluation of our unit, checking everything a/c related inside and out, he diagnosed the problem and gave us options to help save us money now and in the long run. After a deep cleaning of our unit and coils, he had our air working again. Not only working again but working better than it ever has! We are absolutely thrilled with David's service! We are appreciative of how honest he was, his friendly and outgoing personality, his efficiency, and his professionalism. We didn't have to spend a fortune having our a/c repaired as he is very reasonably priced. We will never use another HVAC company again. David is our go-to guy from now on! You are awesome, David, and we can't thank you enough!

I am warm and cozy in my home tonight thanks to David & Goliath HVAC Services. David is a top notch professional in his field and was extremely informative on steps to take to prevent further complications with my system. The flat rate pricing for all customers is budget friendly and that is always a plus in our current economy of inflation. David is very prompt and arrived fifteen minutes early for our scheduled appointment. I highly recommend David & Goliath for all of your HVAC needs! You will not be disappointed!

I called David when one of the big companies that advertises on TV all the time quoted me an outrageous number to replace my forced air unit. David showed up on time later that same afternoon. I showed him the repair/replace estimate and he wasn’t so sure I needed to replace everything. He checked the furnace in the attic tabs then out back. About 10 minutes later he showed me the unit wasn’t running due to the capacitor. All I needed was to replace it. One cheap part and his labor charge and I was all set.

If you want someone prompt, honest and reliable I would call David first. He’s the man!

Ac going out when its 90+ out is never fun. I called multiple companies - about 8 - and only 2 were available the same day. I was comparing availability, diagnostic fees and reviews. Dispite David and Goliath being a newer company, they had many good reviews. David was able to come out within a couple of hours vs an 8 hr window with the other company. This was by the grace of God and the universe since he was right down the road with another repair. Another huge factor in my choice was that his diagnostic fee counts towards repair if you have him do it, which, i find many companies no longer do. He had everything in his van and was able to complete the repairs within a couple of hours. He was detailed in explaining and showing what was wrong and what to except. His pricing was reasonable and he and his helper were pleasant the entire time. He also did not try to sell me a subscription to maintenance my hvac system. I will be calling back if I ever need another service - the number is saved in phone.

I moved to Dallas a year ago and I'm getting to know the companies in the neighborhood. Yesterday I needed a heating mechanic and I researched David's company and only had excellent reviews, so I decided to call him and it was excellent. As soon as I sent a message I received a call and they answered me within 3 hours. The diagnosis was quick and the repair even quicker. David is an excellent professional, intelligent and competent. The price was super fair and the service was exceptional. He will definitely be my home mechanic for many years to come!!!! Thank you David for your speed, honesty and professionalism.
