Tried to install a Nest on my own and ended up breaking my entire system. DallTex serviced my unit the same day as I called, and everything is working as expected now. Couldn't ask much more, perfect 5 stars from me.

I highly recommend Dalltex services my husband and I were very pleased with the quick response to our call they were very prompt, professional, honest and patient. We received service from them last week June 15, 2017 our AC unit went out I prayed for the right person to help us I googled air service in Dville and came across Dalltex I called and spoke with Hector 6ish pm my he took care of us with another unit was up and running by 930pm the hold up was us I must add every review that I read on his company I can attest to his price was excellent lower than all the others and he didn't seem to try and get over on us you could tell he take pride in his work and a true man of integrity again I would recommend anyone in need of air and heating services to this company I will also be writing a review rating through the Better Business Bureau. EXCELLENT excellent excellent customer service excellent personality he was our God sent "angel " in our greatest time of need. God Bless you Dalltex! I pray for even more business (customers) to be sent your way!!

Excellent! I needed our entire 2 unit system replaced, all new ductwork, attic insulation, and replacement of 2 attic fans. I spent almost a month having companies come out to provide estimates. Of the 15 companies who came out to provide estimates, only about 6 actually returned one. Of those, Hector's price was thousands less than the best estimate, and included everything whereas the other estimates were just for the units. But that's not the reason I went with Hector. I went with Hector because of all those who came out to provide estimates, Hector was the only non-salesman. He completed the job when he said he would, and exceeded my expectations. You'd be a fool not to call Hector at DallTex if you have HVAC needs.

I have been using Hector for repairs at my business, Cafe Madrid, and have been VERY pleased with his quick and knowledgeable service! He has saved us money and is always so quick and efficient in responding to our repair needs. He was able to repair a unit that another company told me was not repairable and that I would have to purchase a whole new system!! Hector repaired it and saved me thousands of dollars!!! I wish we would have known about him years ago. Thank you, Hector!

I got home from work and my air conditioner was broken. The temperature in my house was in the 90s. I called several place before Dalltex just because they came up faster on the Google search and none could come out till the following day or had a ridiculous dispatch fee. I called Dalltex and within 20 minutes had someone here. I worked with Hector and he did an incredible job. He was honest and gave up front pricing and walked me through my different options. He was then able to get me fixed up within an hour. Incredible service for a good price. Highly recommended.

We recently moved into a home that we are completely renovating. Hector and his staff were very efficient and worked diligently. Within a matter of time they had 2 units going! Dalltex is very professional, Hector took his time to explain every single thing that needed to be done in our old home that was built in 1937. Thank you Dalltex for working on my home in the middle of a Texas Summer!

Recently moved into a new home and the A/C went out mid-day. We thought it was a thermostat issue (or maybe, I am not as handy as I once thought). That being said, we didn't call him until 5pm which we thought might push the fix until the following day. Hector offered to come by within an hour of that call. Hector figured out the issue and spent the next 1.5 fixing the problem. He could've gone home but took our last minute call and did an amazing job updating and installing the new equipment. I would definitely recommend using Dalltex and Hector is the man.

Hectares was absolutely, positively GREAT! He is a totally awesome technician. He's so nice and friendly. Installed hot water heater and explained every step of the process to me. Very professional and extremely knowledgeable. Pointed out other repairs I need to have done. That's how good he is. Please keep Hectares at DallTex. I'd like to see him rewarded in some way for being an awesome technician as well as an awesome person. He truly represents DallTex in an awesome way. Hector totally rocks!

We were so grateful to have Hector come in within an hour of my phone call! He was thorough, reliable and very helpful and informative. I highly recommend Dalltex for your air conditioning servicing and maintenance needs!!

Our AC started going out, of course right when it's starting to get really hot again in Dallas. I called a couple places and they were busy and short with me on the phone. I called Dalltex, a company in Oak Cliff (we live in Oak Cliff) and they were courteous and were able to come out within an hour and a half. Hector and his technician were very professional, friendly, and knowledgeable. They diagnosed our problem almost instantaneously. He corrected the issue for a very reasonable fee. My wife and I highly recommend Hector and his company Dalltex. They are great! We will always use them and recommend them to our friends and family. If you are having HVAC issues, give Dalltex a call. They will take really good care of you. We thought we were in for a hot hot hot weekend, but Dalltex was awesome and now we are back to cold a/c. Thank you Dalltex, your company is great!!!

My AC blower went out and I randomly ended up calling Dalltex to come out and service the unit. Hector showed up within the hour, quickly diagnosed the problem (blown transformer due to exposed wires causing a short) and got me fixed up and AC blowing within 30 minutes. Easy, quick, painless and honest service. Thank you Hector.

I called Hector and asked for a quote on a new central air conditioner. After receiving the quote, I called him back and I asked for references, he was happy to provide 3 references. The individuals names he provided spoke highly of Hector as a person and the quality of his work. Hector did a great job installing a new central air conditioning system at my home. I will call him about any air conditioning or heating concerns.

Hector called me two days ago and made an appointment to check out my air conditioning problem. He was very polite and most of all he was on time. He told me he would be back Thursday morning and he was!!! He has fixed the problem and the house is beginning to cool down. He checked our compressor and told me it was working fine. He did a great job. I will be happy to recommend your company to all of my friends. Thanks, Hector!!!

Stephanie Dickason, Fantastic! When I had my AC unit go out last summer in 108 heat, Hector was able to completely replace my unit quickly at a very reasonable price. His is the only heating/AC company I will ever use!

Dalltex is absolutely the one of the best around DFW! We recently had our air handler replaced in our attic by another company, then after two months the AC just stopped working, the other company came over and immediately tried selling us the outside unit for 4k+ We already felt that they didn't do a good job the first time and we wanted a 2nd opinion. We came across DallTex and they came in an hour. Hector was professional and very courteous - unlike the other company. He came to the same conclusion but quoted us less than half the price! He made sure everything is working and even made sure the air handler that I previously got was good. I cannot recommend them enough! This company is good! Hector is the man! We normally don't do reviews, but were compelled to on this one as they absolutely deserve it!

Hector is always on time and does what needs to be done, without trying to up sell or pull any tricks. He saved me a major expense several years ago by accurately diagnosing and fixing a unit that another company said needed to be totally replaced. It is still working just fine to this day. A first rate company that deserves a chance at your business. You won't be disappointed.

I've used Dalltex for my ac/heat issues a few times now and Hector comes and gets the job done! Pleasant experience all around and I highly recommend them to anyone.

Hector was on time and handled everything perfectly. I was so happy how quick he responded. He had the parts on his truck so no back and forth. Within 30 minutes everything was up and running.

The guys always do a great job, and are on time. We will definitely use them again when needed.

Very friendly

Absolutely great!! I recently purchased a home that needed 2 completely new systems. Hector worked with me and kept me informed, showed up on time, workers were quick and clean. They answered every question and did a clean professional install. I would highly recommend.

Hector is the best just like all the others say! I feel like i have finally found an a/c man that I can use for life. He figured out the problem in about two minutes. He needed to get a part that wasn't on the truck but it only took him a very short bit to go get it. Once he was back he did all the work in about 30 to 45 minutes. The unit is working excellent now and i can't believe how fast the warehouse is cooling off! Hector showed up in a very reasonable time within the frame they set and is extremely professional! He is someone who i feel i can trust. I highly recommend Hector and the Dalltex company. YOU WILL NOT GO WRONG using them!

DALL-TEX is my new AC company after last year's initial repair of one of my 3 units. Fast, dependable, Honest - finally an honest company, and affordable! They just replace my oldest unit that finally died with a great new unit at a great price. I'm a loyal customer now, and recommend them to all my friends.

Hector with Dalltex fixed my A/C today outside and in the rain! You don't get better customer service that this. They will always be my first call.

As a general contractor , Hector has worked on several clients and my own house. He is always on time, reliable does great work at a fair price
