HVAC reviews in Mokena, Illinois

Service was top-notch from start to finish. I called them on a Sunday and got someone at my doorstep in under 24 hours. The repair took less than 20 minutes. The team was friendly, efficient, and super knowledgeable - you can tell they're pros. I'm hooked on their service, highly recommend Allegiance Heating & Cooling.

We were impressed with Allegiance's performance from start to finish. Their technicians are respectful, on time, and demonstrate expertise in their trade. Clear explanations were provided and the job was done correctly. We're satisfied with the results and can confidently endorse this company for those seeking dependable heating solutions.

This company's technicians arrived on time, dressed professionally, and showed good manners. The duct cleaning and dryer vent services were done well, and the installation of my new furnace and AC was completed efficiently. They clearly take pride in their work. Natalie was very helpful with communication throughout the process. It's clear that the team enjoys their job and has a strong working relationship - this family-run business is definitely recommended for its quality service and friendly staff.

The service tech was knowledgeable and did a good job. Unfortunately, they didn't follow through on the agreed price. I chose to have my humidifier checked for $99 instead of $125 because it would give me the same level of attention at a lower cost. However, I ended up being charged the more expensive option. The billing process was frustrating, and when I brought it up, they became argumentative about crediting me. It's disappointing to be overcharged by such a small amount, especially when it was clearly communicated upfront.

Climate Masters has saved our family twice from a stuffy home - thanks to their swift response, flexible scheduling, and outstanding service. Despite having an antiquated furnace over 20 years old, they didn't recommend replacing it. I'm confident in knowing who to call next time.

Kimie kept me updated on the scheduled visit. The technician, Shawn, seemed knowledgeable about the equipment despite being new to the property. He completed the necessary inspection and repair promptly. The work was done efficiently and at a price I was comfortable with. Overall, a satisfactory experience.

Had my furnace replaced after 26 years of reliable service from my old Bryant unit. As someone familiar with HVAC systems, I was impressed by the quality job Jeff delivered. His team worked efficiently and effectively. Kimmie was courteous, polite, and professional throughout the process. While there might have been cheaper alternatives, I believe you get what you pay for. Overall, I'm satisfied with the service and would recommend them to others who value a good work ethic and quality results.

Mo is great - asked him plenty of questions and got helpful insights. He's friendly, willing to assist, and does a top-notch job. Work is done with care, leaving the space spotless. Highly recommend without hesitation.

I'm extremely satisfied with CMMC's services. They gave me a reasonable quote for the equipment provided, which was beneficial since Carrier and Bryant products are essentially identical but offered at different prices. Chuck conducted a thorough assessment, listened to my needs, outlined the available options, and presented clear pricing for each choice. The installation process was seamless, tidy, and of high quality. After comparing estimates from multiple contractors, I felt most confident in CMMC's product, features, price, and post-sales service, which is why I chose them over others.

Moe stands out as a top performer. His punctuality and attention to detail are noteworthy. What impressed me most was his willingness to wait an additional couple of minutes to ensure the issue was resolved, demonstrating a commitment to quality workmanship.

I was willing to adapt my schedule to meet with Chuck, the owner, for an estimate. Unfortunately, I've seen firsthand how unyielding companies can be when it comes to flexibility. When I mention giving potential customers a written quote, I always deliver. My experience with your company is no exception - despite agreeing to provide a quote, I still haven't received anything by Monday night. It's starting to look like you're not interested in the job at all. Transparency would be appreciated, even if it means saying no. Needless to say, I wouldn't recommend your business to anyone.

Charles was honest about our AC's condition and the repair costs, wanting to make sure we fully understood the scope of work beforehand. This transparency was greatly appreciated, making the process feel more trustworthy.

We've had Climate Master on our team for nearly two decades. They consistently show up on schedule, are friendly and informative, and keep us updated through Kim's regular communication. The technicians are all knowledgeable and prioritize customer satisfaction - we're impressed with their work. Thanks for the great service.

Great service from the start, from initial contact to on-site work. Jeff is direct, reliable, and expert. The job got done fast without sacrificing attention to detail or quality. Overall, this company stands out for its professionalism and high standards.

Moe delivered top-notch service, figuring out my furnace issues and cleaning it within a reasonable price. I appreciate his honesty - that's what sets companies apart. Phone support was also friendly and helpful, making me feel confident in choosing this company for home repairs.

For over two decades, we relied on Climate Master, but after Doornbos acquired them, our yearly service agreement stopped being sent out. Now, they're charging an exorbitant $179 for a furnace cleaning – a price that's laughable considering the value it provides. Needless to say, I'll no longer be using this company for my heating and cooling needs; extremely dissatisfied with the recent changes.

I've had great experiences with Climate Master!

Their office manager, Kimie, is super courteous and organized. She keeps me in the loop with their technicians, so I always know what's going on with my appointment. They seem to genuinely value my business and time.

Shawn, one of the service techs, is also top-notch. He's punctual, knowledgeable, and patient. He takes the time to answer questions and explain things clearly – no nonsense here!

Overall, Climate Master has got you covered for all your HVAC needs!

We had a service call today for our air conditioner, and it couldn't have gone better. The technician who showed up was incredibly competent - we were thoroughly informed about everything. They made sure their shoes were covered before entering the house, which was just one of those nice touches that shows attention to detail. Our questions were all answered and our issues resolved as best they could be (it's hard to get rid of vibrations). We'll definitely be calling them again next time we need service - thanks.

Jeff and Steven did a great job installing our AC, furnaces, and heater in the garage. They showed up on schedule and got the work done as planned. The technicians took the time to explain how everything works and presented a clean finish at every site. I'm extremely satisfied with their professionalism and would definitely recommend them to others.

My AC unit stopped working, but they arranged a visit for the following day. When Jeff arrived, he called ahead to let me know he was on his way and showed up early as scheduled. He quickly identified the issue and presented my options, recommending the most cost-effective solution. I've now used Climate Master twice before and am consistently impressed with their professionalism and integrity.

Moe arrived promptly, completed the job swiftly and effectively, and clearly explained his work. His professionalism and attention to detail were impressive, resulting in a seamless experience. Overall, it was a highly satisfactory encounter that left a positive impression, making me confident in recommending this service provider.
