Excel Geothermal A/C & Heat, LLC

Our nonprofit, Green Careers Dallas is extremely grateful for the wonderful, thorough work done by Excel Geothermal. We needed about 85' of old broken fencing and in-grown trees removed in order to put a new fence in at our new training site in southern Dallas. Since we are operating on a shoestring budge, the owner of Excel Geothermal, Roy Schar, donated this entire day's work, his crew and excavation equipment to get the job done. We do not know how we would have done this without his generosity! For a grassroots nonprofit, this means the world to know a business would do this to get us closer to our dream. Thank you to the wonderful crew and to Mr. Roy Schar at Geothermal Excel!!!

Wow! Amazing service and very fair with their pricing…my builder uses them and they did all of my HVAC and top notch premier service

We've had issues with our Geothermal A/C since we moved into our house last year. We've had a number of HVAC contractors come out to service but none of them could fix it. Finally I called Excel and the experience was night and day. They came out quickly and even after hours. The techs were professional, friendly and when they were not 100% sure about the next step, they called the Owner who came out same day afterhours to diagnose. The system was old and could not be repaired. Roy and his team gave me what felt like a very fair estimate for replacement, they ordered the equipment and it was installed again afterhours within days!

This is the crew you want if you are looking for a reliable, honest HVAC contractor. I wish for them to have a long and prosperous business , the deserve it.

Great customer service, responsive, thoughtful, on time and professional. We had a prior company which was really bad. Excel was a breath of fresh air. Great folks, highly recommend!

I only take the time to write a review when a company does an outstanding job and this company performed above and beyond. I purchased a home with Casa Belle Homes however my AC system was warrantied and installed by Excel Geothermal. There was an issue with one room being much hotter than the other rooms. After 2 techs could not resolved the problem, I was getting very upset however, the President of the company came out and was able to resolve the problem at no cost to me. I have never met any business that stands behind their work in the manner that this company did. They came over in the poring down rain and fixed everything and even added some additional equipment to help my system work at it’s best. I highly recommend them.

I chose Excel because of all the good reviews. And just like everyone said! Great service! Darcel was professional timely and very informative! He did a great job! Love that the staff knows their job well though I’ve had others out that couldn’t help me but charged a hefty fee. So thanks a lot! I would definitely recommend this company

Roy and his crew at Excel gets a five ⭐️ rating from us only because there is not a 10 star available to give, Top notch knowledge of Geothermal AC backed up by impeccable service. Staying cool thanks to Excel.

I have nothing but good things to say about Excel. I have a geo thermal system and wanted to have it inspected. Darcell was professional and thorough. He explained to me in great detail how the system works and what his inspection entailed. I'll be having them back out twice a year going forward for inspections. My system actually shut down a few days ago, so I had Isaiah out to have a look. Within half an hour he determined there were air bubbles in the water line that triggered a sensor to shut the system off to avoid any damage. It took him all of 30 minutes and I was back up and running. Do not hesitate to use Excel Geothermal A/C & Heat. They rock!

We were delighted to see that our previous technician, Mario Escobar , is now working for Excel. Thorough, professional and friendly . Previous experience with Mario tells me that Excel hires great people . Glad to have Excel on the job to keep our older geothermal system running at its best.

Truly a company of probity, aptitude, and conscientious customer service, Excel Geothermal expertly replaced my conventional system with an ultra-efficient one and also insulated my rafters with spray-foam, further reducing my monthly electric bills. I enthusiastically give Excel my highest recommendation! You will not be disappointed! Roy and his team of specialists masterly assessed my needs, proposed the best practical solution, then punctiliously proceeded to transform my abode from inefficient, electricity guzzling ogre to an energy-saving, fuel-efficient home where now, for the first time, all my rooms heat and cool properly and I can set the thermostat at the temperature I desire without fear of breaking the bank.
