HVAC reviews in Aurora, Illinois

They are good but couldn’t able to fix the issue. Still humidifier is leaking with few drops. They said Marcos will bring new filter and fix the issue.

Marco was extremely helpful answering all my questions. He was able to install a new complete system the next day. I recommend Maximum Heating and Air Conditioning for all services.

Wonderful service! I called early and this Saturday morning and they came out right away. We were able to fix the problem and a fear and reasonable price. Highly recommend.

Very easy to schedule with and great overall communication. Technician was delayed, but they called and let me know. Ended up having issues with my furnace that they explained clearly and straight forward. Get it fixed the same day and made sure everything was working before they left.

The crew that installed my water heater was friendly and professional. When they were done they cleaned up after themselves and went as far as wiping down the walls and door fram. I would definitely use them again if needed and would recommend them to anyone.

Marco and his team are great to work with- they provide competitive pricing and are always available when there are issues with my sumo pump and humidifier - the team provides several options, solutions to any problem you may have. Great team overall!

I had a problem with my furnace, and Marco made time to come out that same day! He figured out what was wrong and got it fixed right away under warranty. While he was there, he also did the seasonal maintenance/cleaning I needed too. Great work!

Amazing service from start to finish! The team at Maximum Heating & Air Conditioning was extremely professional, punctual, and detail-oriented. The quality of work was excellent, everything was left clean and neat, and the pricing was very reasonable for the level of service provided. Overall, it was a great experience and I would absolutely recommend Maximum Heating & Air Conditioning to anyone looking for reliable, high-quality HVAC service.

My heat went down. I called them. They came right away. They got my heat working. They didn’t charge me. The following day They came and replaced my exhaust motor and cleaned my ducts. They guaranteed their work and parts. I highly recommend.

We had some unexpected issues after moving back into our home this fall. First, we noticed a slight gas smell in the basement, and our CO₂ alarm kept going off, so we had to call the gas company to check for leaks. Around the same time—right before Thanksgiving—the weather dropped and our furnace suddenly stopped staying on or heating properly.

Our contractor contacted Maximum Heating and Air Conditioning, and they came out within a couple of hours. During the first visit the furnace seemed to work, but about 15 minutes after they left it shut off again. I reached back out, and they returned within three hours. They immediately noticed the furnace was behaving oddly. Marcos suspected a vent issue and, even though it was already dark outside, he got the furnace running well enough to keep us warm overnight.

The team came back the next day and discovered the real issue: the exterior vent had been covered by wood and siding during other work on the house. Once they uncovered it, the furnace worked perfectly—and the gas smell disappeared.

Throughout this entire process, their customer service provided by Marco was outstanding. He answered all my questions, responded quickly to text messages, and carried themselves with complete professionalism. They were patient, thorough, and genuinely committed to making sure our home was safe and warm.

I highly recommend Marco from Maximum Heating and Air Conditioning for their expertise, responsiveness, and exceptional customer service.

Furnace went out the Tuesday before Thanksgiving and called Youngren’s given they did some previous work at my old house in Aurora. I was a bit worried they didn’t cover Lisle but am happy they do. Fantastic service all around and wouldn’t hesitate to call them again in the future. Full HVAC replacement given the age of my equipment(27years)! Solid service and solid people with competitive pricing.

Technican Colton advised us on the furnace/ ac cleaning service for which we signed up for. Promptly arrived and very friendly. He explained all procedures and did an excellent job. Looking forward to the spring for the air conditioning cleaning. Hugo did a great job for our spring service

I have Youngren’s as my A/C and furnace maintenance company. I have to say they are THE best. They are ALWAYS on time, cover their shoes with protector covers, and are so completely thorough with their service. They clean up after themselves if necessary and are respectful of my home and property.
You need to give them a try. I know you’ll be happy.

This was our first time using Youngren’s. They came out quickly, were professional, honest and were very fair in their pricing! They didn’t try to oversell and while they were able to fix our AC they were honest about the age and lifespan of our unit. Even with an older unit I am thankful that they were able to fix it instead of just trying to sell us a whole new system. I would highly recommend this company!

Service was performed on my furnace. The tech was able to answer my questions. Highly satisfied!

Excellent service. Hugo was here to evaluate my AC, Water Heater and Furnace. He was prompt, informative and Professional. Set up a time to get a water heater replacement completed. Andy and co-worker were here on time. Provided excellent and professional service. I highly recommend Youngren’s.

Trusted this company with a purchase 6 years ago. I am satisfied and the maintenance service contract is great. Joe, the technician pro, came out in October of 2025 and was meticulously detailed and assured me that my furnace was cleaned and checked. I would buy from Youngrens again. The new sales person is Tom Z if curious in a getting a quote.

My furnace went out on the coldest day of the year, of course! Called Youngren’s and they had someone at my door in 30 minutes. My house was toasty warm in no time. Would not hesitate to call them again for all of our hearing and cooling needs. You won’t be disappointed!

We've used Youngren's for many years. They have always been thorough, honest, prompt, and fair. This past visit our technician was knowledgeable, experienced, courteous, and very efficient.

Over the last few years, they’ve replaced both the furnace and AC. No problems whatsoever!
