All reviews for Allegiance Heating & Cooling

We're extremely satisfied with Allegiance's service. Our AC stopped working on a scorching summer day, but they sent someone over that same afternoon - impressive. Natalie was great to work with and got us fixed up quickly. Highly recommend them - they really delivered when it mattered most.

Riley and Donny did a great job, answering all my queries and leaving the site spotless.

Allegiance is the go-to for HVAC services without a doubt. Their team, which includes Jack, Mike, Joey, and John, turned our 4th of July morning disaster into an opportunity when our AC gave out on the hottest day of the year. They were friendly, prompt, and thorough in their work. Despite being able to complete the job before noon, they made sure we had a reliable system in place for the rest of the summer. I can confidently say Allegiance is the best option - hands down.

Our AC failed during a heatwave, and we had a few unimpressive experiences with other companies' customer service. However, Allegiance stood out from the crowd. Their representative on the phone was friendly and attentive, showing genuine interest in resolving our issue. What impressed us most was their swift response - they arrived earlier than any of the other companies we contacted. Throughout the process, we received regular updates via phone and text, keeping us informed about the status of our technician's arrival. Our technician, Donnie, was excellent - he took the time to explain everything clearly to my husband. We ended up needing a capacitor replacement, which cost $65 for their initial visit. After the repairs, the total bill was around $450. Given their professionalism and responsiveness, we're confident in choosing Allegiance for our future HVAC needs.

I've had an incredible experience with Allegiance from start to finish. From the initial call, their customer service was impeccable - friendly, prompt, and expertly informed.

Allegiance responded promptly to our call and scheduled an appointment on the same day. Their technician, Donnie, arrived quickly and was courteous, explaining everything clearly. The repair was done efficiently and effectively, getting our unit up and running in no time. We're very satisfied with the service and would definitely recommend Allegiance for any future needs.

On Sunday, I caught my AC blower leaking down in the basement. A representative from Allegiance arrived bright and early on Monday to help me out. The technician tackled multiple potential causes before pinpointing the issue – a clogged condensate drain line. Notably, this line was located in a tricky spot. Despite that, the tech managed to locate the blockage, clear it out, and swap all the old PVC pipes with new ones. He also re-routed the drain line in a better configuration. I'm thoroughly satisfied with Allegiance's prompt service and response time.

Joey showed up right on schedule and got straight to work. He ran some tests, diagnosed the issue, and replaced just the faulty part - my AC was back in working order. What a relief not to have had to replace the whole unit. Highly professional service and impressed with his expertise.

Riley's visit was thorough and informative. He identified a significant issue with our heating system that needs attention. His professionalism and concern for safety are greatly appreciated, especially when it comes to keeping my family protected.

Donnie showed up right on schedule and worked efficiently. When he realized the old air filter was gone, he headed back to the office to retrieve a replacement - no fuss at all. This guy is top-notch service.

Riley did a great job on my condensation issue - he pinpointed the problem in the pipe, removed the faulty section, cleared the line, and replaced it. The whole process took less than an hour. He's knowledgeable, efficient, and courteous. Highly recommend this service!

Hands down the best choice for any home services needs. This family-owned business genuinely puts customers first, offering reasonable prices and top-notch service. Their dedication to satisfaction is unwavering – don't hesitate, they're worth choosing over anyone else.

We're back with this company again. Their service was top-notch, but our experience wasn't so great initially - another company tried to pull the wool over my eyes with scare tactics to sell me something I didn't need. Thankfully, they showed up and proved them wrong. We've since used their services and will definitely be back, so give them a try if you're in a similar situation.

I recently had my AC serviced by Allegiance, and I'm extremely pleased with the results. The technician did a fantastic job, completing the repairs in a timely manner. They were able to source a replacement motor quickly, ensuring my family stayed cool during the warm weather. The cost was very fair, considering the quality of work.

What impressed me most was their excellent communication skills and genuine knowledge. I was kept informed throughout the process, and the team made sure I understood everything clearly. Their priority was getting my AC up and running as soon as possible. I wholeheartedly recommend Allegiance, and I'd like to extend a special thank you to the technician who did such an outstanding job for me.

We recently moved into our home and discovered some HVAC venting issues during the inspection. Allegiance Heating responded quickly and efficiently, addressing everything within a week of us moving in. Our technicians, Donnie G., Riley, and Jack G., were top-notch - they took the time to thoroughly explain the process to my wife and me, and we were genuinely impressed with their professionalism and courtesy.

Allegiance got my vent cleaning done on the same day, which was convenient. The technician, Riley, was courteous and respectful of my space, taking the time to explain what he was doing. He left my place tidy afterwards too - would definitely suggest Allegiance.

This technician was extremely courteous and helped me greatly with cleaning my furnace. He took the time to explain everything clearly. If I could, I'd give him more than five stars - he truly deserved it. Allegiance is lucky to have him on staff.

They provided great customer service when finding a new motor for my furnace in Tinley Park, got it installed within 45 minutes, and even returned to my house to fix it. The staff were friendly and efficient, making the process smooth and hassle-free.

John's team was top-notch - Riley, John and David all delivered exceptional service from start to finish, earning my highest recommendation.

Riley was very professional and got the job done fast. The work was efficient and I'd definitely use their services again and pass on the referral.

Riley did a great job, it seems. He finished his work and I was able to start the AC. The unit is running smoothly, but I still can't gauge the furnace's performance since it's not dropping the temperature by enough for me to notice the difference.
