HVAC reviews in Romeoville, Illinois

Francisco did a phenomenal job working on our air conditioner. He was professional, trustworthy, and clearly knew what he was doing. I really appreciated how personable and easy to talk to he was—he made the whole process feel simple and stress-free.

What really stood out was his trustworthiness. It’s rare these days to find someone you can genuinely feel confident having in your home and trusting with your equipment. Francisco worked efficiently, respected my space, and left everything cleaner than he found it.

Not only did he do a phenomenal job with the HVAC system—everything runs perfectly now—but he was also just a really great guy to talk to. Friendly, down-to-earth, and clearly passionate about what he does.

It’s not always easy to find someone you can count on these days, but Francisco is definitely one of those people. I wouldn’t hesitate to call him again or recommend him to others. Great experience all around!

Scammers please avoid!!!

They are efficient and come quickly. That’s the only upside. However, they tried to scam me:
My unit wasn’t cooling down, so I had them come and check the compressor. After a few minutes they told me I needed an new compressor which would be $5900.

The next day I had a different company come in to confirm the issue, and they said that the United took out my battery, and in addition they scratched certain numbers on the compressor, so the new company couldn’t identify which type of compressor it was. After a little bit of research they were able to figure it out and fixed the issue with a different battery. He charged me $250, and the issue was resolved.
I am happy that I didn’t pay these scammers $5900!!! PLEASE AVOID if you can.

We had a great experience with this company. Very nice and communicated everything. They were very quick, fixed the issue and my AC is working again. Cost was great as well! Highly recommend. Definitely trustworthy and friendly as other comments have stated.

The United Heating and AC team of Francisco, Vicente and Don Miguel are hardworking, true professionals. They are reliable, dependable and do quality work at a great price! I will definitely use them for all my HVAC needs going forward!!!

We've worked with Good Shepherd twice - once for AC maintenance and most recently for a water heater replacement. They arrived on time, completed the job swiftly, and left everything tidy. The technicians were friendly and reliable. It's great to have companies like them that keep their promises.

I was extremely satisfied with David's recent installation of a new AC system in my home. His professionalism and work ethic were top-notch, delivering a solid product at a reasonable price. I'm already recommending him to all my family members for future heating and cooling needs - don't hesitate to contact him yourself.

They showed up quickly in response to our breakdown. Their technician checked every aspect of the system and found a faulty component that needed replacing, which they did on the same visit. They also gave our unit a thorough cleaning as part of the service. Given the time invested, we thought the price was fair. We're satisfied enough with their work that we're booking them again to fix a water heater issue.

We've hired David multiple times for air conditioning, furnace, and now water heater work. I highly endorse him - he's a top-notch professional who consistently delivers excellent service. His willingness to accommodate our schedule, including an evening replacement of our water heater on short notice, is impressive.

I came home to a furnace that wasn't working, with a burning smell, and the smoke alarm went off as soon as I walked in. Luckily, Good Shepherd was available, and their owner showed up within an hour. He fixed the issue by replacing a component and gave it a good cleaning. Given the price, I'm extremely satisfied - it was much cheaper than what I'd expect from another company. The owner also checked on me later to make sure everything was okay, which is more than I can say for some other services. David is friendly, knowledgeable, and reasonably priced. I'll definitely call him again if there are any future issues!

I'm thoroughly impressed with Good Shepherd's home services. The tech I dealt with was top-notch - knowledgeable, courteous, and efficient. They diagnosed the issue quickly, replaced the faulty parts, and got me back up and running. Given it was a Saturday evening and they still managed to fit me in on short notice, I think their pricing is very reasonable. I'll definitely be using them again and recommending them to anyone who needs reliable service.

Excellent service from a highly professional team. I called late in the evening, hoping for same-day assistance, and was thrilled when David arrived at my doorstep just 15 minutes after my call. The level of expertise and courtesy is top-notch – if you require HVAC services, Good Shepherd is the only choice. I'm thoroughly impressed with both the service and value.

Good Shepherd Heating is top-notch. They deliver exceptional service and meticulous work. I've relied on them exclusively for my AC upkeep and repairs.

Great service from Good Shepherd! They really know their stuff. I previously had another AC repair guy do a quick fill for $280, but my AC only lasted 3 weeks before running out of cold air again. When I called him back, he was stumped.

On Sunday, I reached out to Good Shepherd and David came over the next day to assess the issue. Unlike the other guy, who barely took a glance, David measured plenty of things to diagnose the problem. He fixed it quickly and effectively, and the price was significantly lower than what I paid for the initial fix.

David did an excellent job, and I'm grateful for his professionalism and expertise.

I reached out to David during the holiday season, concerned about a leaky water heater. He responded quickly and assessed the issue, suggesting replacement. The next day, he installed a new unit at a reasonable price. What impressed me was his thoroughness - he took time to explain proper maintenance for my water heater's temperature controls, as well as my furnace and AC units, to extend their lifespan. He even threw in a free air filter installation. David's professionalism and expertise were evident throughout the process. His services are trustworthy, and I'd highly recommend him to anyone needing his help.

Our technician showed up remarkably quickly after we called in the issue and got the faulty capacitor fixed efficiently. The service guy was pleasant, speedy, and on top of his game. We're sticking with them for all our heating and cooling fixes.

This guy is the real deal - five stars isn't enough. He showed up on time both times he serviced my furnace and water heater, and did it with a level of professionalism that's hard to find. If you leave him a message, be patient - he might not get right back to you, but trust me, he'll call as soon as he can, no strings attached. He's not out to make a quick buck off you like those big company guys are. In fact, he'll even check your warranty status before selling you a new one, which could save you even more cash. What I appreciate most is that he takes the time to explain everything in a way that makes sense, and isn't afraid to answer tough questions. He's also got some valuable tips on maintenance that can help extend the life of your equipment. This guy runs an honest business, and it shows - good luck finding someone like him.

Called several places with good reviews. Found David who was professional, courteous, offered the best price, and showed up that day to clean my furnace. He took his time, did a great job, provided valuable tips on maintenance, and threw in another discount. Truly impressed with his skills and fair pricing. Would highly recommend him to anyone looking for reliable service.

I recently used Good Shepherd's services and the experience was overwhelmingly positive. The initial call was helpful as they walked me through troubleshooting to see if I could resolve the issue on my own. When it became clear that a replacement part was needed, their technician arrived promptly and efficiently replaced the part, getting my furnace up and running again soon after. They also provided valuable information about my specific furnace, filters, and maintenance needs. Throughout the process, I found them to be courteous, knowledgeable, and reasonably priced.

I've used The Good Shepherd Heating Air Conditioning & Refrigeration twice now, and both times I felt confident in their expertise. Last year, the technician explained everything clearly as he diagnosed the issue with my AC unit - it just needed a charge, which was good to know since I'd been told it might be more extensive if the unit couldn't hold that charge. This year, when I suspected a similar problem, the same technician came and reassured me again, this time telling me the charge still looked good from last year's visit and that a module was the issue. He had one in his truck and fixed my unit in under 30 minutes. His professionalism, combined with his honesty, makes me trust him completely - I'll definitely recommend him to others.

I'm still reeling from the second time they saved my day with their lightning-fast response. My air con broke down again and I desperately needed a fix - same-day service would have been a dream come true, but Good Shepherd delivered nonetheless.

Every single company I contacted was either slammed or couldn't make it for days, leaving me sweating it out at home. But not Good Shepherd - they called back within an hour of leaving a message and showed up a few hours later. Their guy whipped that problem into shape in a hair's breadth of 20 minutes.

I've got to say, I'm thoroughly impressed with their professionalism and work ethic. My place was a scorching 89 degrees when they arrived, so it wasn't exactly a walk in the park, but they handled it like pros. You can bet I'll be going back to them for any future heating or cooling needs - thanks again!
