“2nd time having Rozga to help us out. Ray was so helpful and fast at fixing our issue! Rozga is the most professional company with great communication. I will definitely call for future needs. Thank you!“

“Called Thielmann to have some service completed with a old copper pipe that was leaking in a difficult location in a finished basement (behind a drywall ceiling). Spoke with Jodi who was able to schedule me a few days out, Dan E and his apprentice showed up on the scheduled time with plenty of communication as to where to go.

Dan was very professional in evaluating the leak, situation, and need for repair. Took them less than a half hour to finish the job and to verify the work completed for leaks. Thielmann warrants their work completed and this company will be my first call again for any issues plumbing or HVAC related issue with my home.“

He answered all the questions we had even made effort to find out our unit serial number which missed for some reason, it will be easier for the future needs. He recommended adding more freon and cleaning up the unit and checking out everything that makes sure everything was working normally. Job well done. Thank you Rob! Because of him I will definitely do the business with them again and recommend to others!“

“Our furnace stopped blowing air and was giving off a burning smell. We decided to go with Third Coast because of the reviews and we definitely did not regret that choice. They came to the house right away, diagnosed the problem, and had the furnace up and running faster than I would have predicted. They were very upfront about pricing for a repair. Our unit is pretty old; they were honest about how much life it had left but there wasn’t pressure to immediately replace it. I would highly recommend Third Coast for your furnace needs. We will be keeping them in mind for when the time comes to replace the old furnace.“

“Sara and Steve were great working me in durring this brutal heatwave. Max the technician was extremely knowledgeable and professional. Great service at a great price. 5 stars for sure!“

“Just got my HVAC system replaced by Heating and Cooling DRS. The old 80% furnace was replaced with a fuel efficient 97% Lennox elite series furnace. The whole process was super smooth and quick. William was super helpful in explaining to me the differences between different types of furnaces and made the whole process super easy. Highly recommend Heating and Cooling DRS.“

“Garrett came promptly, fixed my air conditioner within an hour. The key to having a successful business is having fair prices and knowledgeable people. Thanks, I will definitely use you again“

“Our HVAC was original to the house and of course, our furnace failed on one of the coldest weekends of the year. We knew it was beyond repair……
We were able to speak with Blake Seider and he connected us with John (the estimator) and we were able to order a new furnace (and A/C) by Saturday night. They came to install it first thing Monday morning. The entire process was seamless and I could not be happier…..I highly recommend them!“

“I was in need of a new boiler during the worst time of the year. I contacted 3 different companies starting with the company who installed my original Boiler and had been servicing it for the past 15 years. I will not name the competitors but I will say Heating and Cooling Drs was by far the best option. What set them apart was their quick response, professional approach and real true pricing. I never felt like i was being sold. I did my own research and the Boiler they installed happens to be one of the best Boilers on the market. Not only did Heating and Cooling Drs come in at a lower price...they installed a top notch Boiler coupled with trouble free service. Alex was my sales guy and I must say...the dude knew what he was talking about. I'm a natural skeptic and to ease my anxiety...they actually had their engineer review my job to reassure me that I was getting the right size Boiler for my home. I couldn't be happier. Thanks guys...You get FIVE Stars in my book!“

“Cas was an excellent technician arrived right on time, very professional and courteous. Did a first class job. I would highly recommend him.“

“I've been using D & M since I bought my house 2 1/2 years ago. Tim's been coming out biannually for routine maintenance/cleaning of my furnace and A/C and has been consistently professional, prompt, and friendly. I very much appreciate the advice he offers (some of it's even regular home advice...things I didn't know, since this is my first home. He doesn't have to tell me these things, but he goes above and beyond) and his thorough explanations, since he has to break it down for me. I also appreciated last year's forewarning about my most likely needing a new furnace this year, so it didn't come as an unforseen expense. The guys just left a bit ago from installing it today, and they were also very professional and courteous. And last, but not least, the ladies in the the office are always very helpful and pleasant to deal with. That said, I highly recommend D & M.

Update (7/10/26): It wouldn't allow me to leave a new review, so I'm adding to this one, years later. I'm still with D &M, receiving the same, consistent service. My A/C was no longer blowing cold air, so I called this a.m. to see if anyone could come out. I was given the 12:30-4:30 time slot, but possibly earlier. I was fully prepared to need a new unit, but Tim got here, found that it was just the capacitor, and had it replaced just before noon. I've always appreciated their timeliness, professionalism, and HONESTY. Thanks, Tim amd D & M!“

“Logan and Zac were very professional as well as helpful and knowledgeable in explaining what the issues were with our furnace and water heater. Both made the problems easier to understand and to process.“

“Miguel's crew is without a doubt the hardest working and most respectful crew ever. Grateful.“

“This was our first time having Gross come out to inspect our central air system. Our technician Doug P was kind, knowledgeable, respectful, honest, and thorough. He informed me of some potential issues with my system down the line and replaced what was needed. He even gave me tips on how to keep our system running optimally. He didn’t try to upsell me on anything and left our system in much better shape than before he arrived. I’ll definitely be using your company again. Thanks!“

“Very knowledgeable and explained process to replace furnace. Completed work within estimated timeframe.“

“Everything you want in a HVAC provider: listened to our needs, gave us practical solutions in a range of options; professional and super conscientious of our home.“

“Very professional, explained everything in detail. They cleaned everything up so there was nothing left laying around.“

“Wonderful service, quick, and easy. We requested an estimate and the salesman was right on time, took a quick look, and quoted is right away. He wasn't pushy, just provided the information necessary for us to make a decision. Once we did, they were able to get techs here within a week, they were early, did a great job, cleaned everything, and informed me on everything I needed to know and answered my questions (Matt was great!). I will definitely recommend to everyone.“

“Brian is extremely knowledgeable, as well as honest - he was real with us and did not try to upsell! I appreciated this a lot, especially considering that some other businesses that quoted us were much more sales-y. He also went above and beyond by successfully helping us troubleshoot an old furnace issue over the phone on another occasion. I would definitely go with this company in the future!“

“Great experience with Deframe and team from Devix. They were installing new HVAC at my neighbor's house so I decided to contact them as we were in need of a new central air unit and I'm so glad that I did! Deframe went above and beyond to coordinate their install with some landscape work we have going on and the entire process was seamless from start to finish. I highly recommend Devix Heating and Cooling.“
