All reviews for David & Goliath HVAC

David was amazing to work with! His response time & professionalism are unmatched. We've had the same struggles with our heat pump for YEARS and have had multiple companies out to look at it, with no real diagnosis or solution. David quickly diagnosed the problem and gave us a super affordable solution! He was extremely thorough and discovered some big issues that were missed by everyone else. I can't recommend him enough! THANK YOU DAVID!

I called David and explained the problem we were experiencing with our AC . He asked for my address and arrived within 30 min and within an hour of the phone call he had our unit up and running. David is very knowledgeable and totally thorough. I highly recommend this company to anyone. Remember , support small buisness.

My AC stopped cooling and I was worried that I was going to have to replace the unit due to how old it was. I immediately started checking out small local HVAC companies because I know how the large companies like to rip you off plus I always prefer to support local small businesses. David returned my phone call in no time, showed up when he said he would, checked out my system and gave me a very fair estimate. He never once tried to puch me to replace anything that didn't need to be replaced and he did an awesome job! I will never call on anyone else again for HVAC needs. Thanks David and I'm looking forward to giving you more business in the future when needed!!

I couldn’t recommend David enough! Through several HVAC vendors dealing with an apartment complex - he by far has been the best we’ve came across. He responds immediately and has always been out the same day for us!

I HAVE NEVER….BEEN SO IMPRESSED!
David was a breath of fresh air! He was quick (within 24 hours) to get back to me to schedule a quote. He came out and his price was reasonable, he gave me some very helpful information and options for what I needed (put a mini split in a building) and I told him I trust his judgement. He walked me through what would be best for the room, best quality and location. He came out BY HIMSELF, put in the unit all within an 8 hour day! He came back a few days later to install a “pretty” fence around the outdoor unit at his suggestion and he checked the unit to make it was to my liking! He even registered the units for the warranty stuff for me! I will be using him for EVERY SINGLE HVAC NEED!

David, with David & Goliath HVAC, did a great job replacing my old duct work. He showed up when he said he would. And he preformed the work he quoted with no surprises. I recommend David for your HVAC system needs.

I called and left a message with David and he returned my call right away. He was very informative and explained everything to me and gave an estimate as much as he could not knowing the unit yet. He solved the issue and saved money by being honest and totally efficient. Good experience for me!!! And he is cute. Lol that is coming from a great grandmothers point of view.

Great, prompt service. Reasonable price. Called David and he came out the same day. Gave me options on replacing the thermostat and cleaned the unit. Will definitely call him back if thermostat continues to malfunction! Five star service!

David was very dependable, knowledgeable and professional. I contacted him and he responded quickly! Came out to service to insure that we will have cool air and an efficient unit! He took his time to explain things. I highly recommend!

Very respectful, well mannered, knowledgeable young man! He went above & beyond to make sure he fixed our issue and made sure there wasn’t any other underlying issues that we were unaware of & indeed found something. He not only fixed our problem but fixed other things that we didn’t even know about & informed us through the whole process. His father taught him well & should be proud!

David did a wonderful job, was on time, good price and great guy. Will tell everyone that needs HVAC work, David is the man to call. I will certainly use him again.

David is a super nice guy and a Man of God. So grateful I found him!
When I spoke with him about my issue, he was willing to come out that same day. I told him it was not an emergency and he came out early the next morning to Diagnosis my unit. After arriving he quickly went to work and made the adjustments needed. Cleaned up some of the areas that were in need and noted on the unit that a different freon is now being used.
He is very knowledgeable about his trade and recommended that we use a replacement for the very pricey freon currently in my unit. My A/C has never been colder than it is now.
I will be recommending him to everyone I know!
Thank you David and Goliath!
May God bless you and your business going forward!

David came straight out when my AC wasn’t working. He was able to diagnose and fix the problem in a very timely manner with a very reasonable price. He was very knowledgeable and very kind. Kindness goes a long way, especially now! I will definitely be using him for any issues in the future!!!

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.
