HVAC reviews in Garland, Texas

Joseph has been servicing my HVAC systems for the past 5+ years; consequently, I was excited to hear he opened ESG. He is a man of integrity and professionalism.

Since ESG opened I have signed an annual maintenance agreement and have needed 2 calls for service, one on each unit. In each case, ESG was able to accommodate my schedule and have my air conditioning fixed immediately. In one instance they came after hours knowing expected temperatures the following day were expected to exceed 90.

Joseph & his team are fantastic!!! He’s done excellent HVAC work on my business! My AC was 18 years old, and I had 3 HVAC guys come out. The first 2 said we needed to spend 10-15K replacing the unit. 2 years later, Joseph is still maintaining the existing unit & we’ve had no problems. This guy is fantastic & knows what he’s doing!

Joseph helped us with an HVAC tune up and ducting repair. He came out quickly, communicated well, and even gave us recommendations for other contractors we needed to come out.

ESG HVAC & Indoor Air Quality is hands down one of the most trustworthy companies I’ve ever worked with. From the moment I reached out, their customer service was top-notch—friendly, helpful, and genuinely invested in making sure I understood the process. The employees were not only professional and knowledgeable but also incredibly personable, which made the entire experience smooth and stress-free. They showed up on time, did excellent work, and didn’t try to upsell anything I didn’t need. You can tell they truly care about their customers. I highly recommend ESG to anyone looking for honest, reliable HVAC service you can count on.

Outstanding HVAC Service – Highly Recommend!

I recently had the pleasure of working with ESG HVAC, and I couldn’t be more impressed with the level of professionalism, expertise, and customer care they provided. From the moment I called to schedule a service, the team was prompt, courteous, and incredibly knowledgeable.
Their technician arrived right on time, thoroughly assessed the issue, and explained everything in clear, understandable terms. What really stood out was their honesty and attention to detail — there was no upselling or unnecessary repairs, just straightforward solutions that got my system running efficiently again.
The work was completed quickly and with high-quality craftsmanship. Since the repair, my HVAC system has been running better than ever. They even followed up a few days later to ensure everything was still working smoothly — a rare and much-appreciated touch.
If you’re looking for an HVAC company that’s reliable, transparent, and truly cares about its customers, look no further than ESG HVAC
I highly recommend them and will definitely be using their services again in the future.
I have had services done both at my home and my business and they have made a client for life.

I've had great experiences with ESG in maintaining my AC at home. They've been quick to arrive and help resolve issues. Competitive pricing too! Would highly recommend.

Scheduling was super easy, and he showed up right on time. I asked for a second opinion on a new unit that had just been installed by another company, and he quickly figured out the issues and gave me clear next steps to get it running like it should. I’d definitely recommend this company and will be using them for any future HVAC work.

Had the pleasure of having Joseph come to my home and fix my furnace. He was able to diagnosed the issue and the reason I called ESG was because someone else quoted me for a new furnace. Joseph was able to fix it at a reasonable price in which I was happy. Found my new HVAC company!!

I recently had another company install my units but felt something was off as it wasn't cooling the same as before. A friend of mine told me about ESG so I paid them to come look at my newly installed system. Joseph found out that a lot of the duct work wasn't sealed properly and taking in attic heat. He sealed everything very nicely on several ducts and he was in and out. My system works as it should now! Best part he didn't even charge me and just asked that if I ever need an AC person to give him a call. He will have my business moving forward! Thank you so much.

I can’t recommend E.S.G. HVAC and indoor air quality enough. My husband and I just wanted to get our air ducts cleaned. We received several other quotes from different companies that were insanely high. Some other companies were even quoting us to replace the whole furnace System totaling around 16k.
Our friends referred us to ESG and I’m so grateful that they did. The technician came in and did a thorough evaluation of both of our systems and ductwork. He was extremely transparent about the repairs that he advised us to do rather than a full system replacement. We also decided to move forward and get our ducks cleaned with E.S.G. they did an incredible job and can’t recommend them enough for their transparency and professionalism.
