HVAC reviews in Cedar Lake, Indiana

The customer received top-notch service throughout. From initial chats with Dan to the final product delivered by Alex and Ethan, everything went smoothly and professionally. The level of satisfaction is extremely high.

First-time customer here. Pleasantly surprised to be able to schedule on a Saturday. Received great service from friendly, efficient, and professional staff with reasonable pricing.

I'm extremely satisfied with Illiana Heating and Cooling after a rocky start. They initially cancelled my appointment but made up for it by arriving promptly on Sunday to tackle the impending cold snap. My technician, Andres, was outstanding - friendly, knowledgeable, and very professional. I'll be calling them for all my HVAC needs going forward.

Excellent service from start to finish. My technicians worked efficiently to accommodate our unique setup, with no hiccups. They provided thorough explanations of the system, tips on maintenance, and were happy to answer any questions I had. The entire process was hassle-free and straightforward, making it a positive experience for everyone involved.

The company delivers excellent service, arriving on time with fair pricing. Their staff is courteous and polite, with friendly and approachable employees like Tony who consistently meet expectations.

I'm extremely dissatisfied with the service I received from this company. When I called about issues with my thermostat, a technician arrived quickly and found the problem - the batteries were dead. The assessment took only two minutes, which seems excessively long given the simplicity of the issue. The charge of $99.00 was also unjustified in my view. It's one thing to have a transportation fee, but not for such a brief diagnosis. What's more concerning is that this company claims to be based on Christian values yet they took advantage of me in such a way. I question their integrity and sense of fairness. I wouldn't pay $99.00 for a two-minute assessment and two dead batteries - it just doesn't add up. The fact that money seems to outweigh customer concerns, reputation, and values is deeply disheartening.

Here's a rewritten version of the review:

Our aging boiler always seems to malfunction around this time every year. KP arrived promptly, displaying exceptional expertise and courtesy. His meticulous approach pinpointed several issues, offering us multiple solutions. The company's overall service is top-notch - fast response times and clear communication make them an excellent choice for our needs.

We encountered some scheduling issues initially, but the team remained super courteous and apologetic. The job was done exceptionally well, with clear communication throughout. They even sent photos of their work to my email for proof. Overall, a top-notch experience - highly recommended without reservation.

The air duct cleaning service exceeded expectations with prompt, informative, and friendly customer service. Technicians arrived on schedule, worked meticulously, and respected the deadline. They demonstrated understanding of the importance of timely completion. The overall experience was exceptional, leading me to choose this company again and recommend it to others.

The technician responded promptly to my request. Jerry was courteous and familiar with the issue, correctly identifying the faulty circuit board. His replacement resolved the problem, restoring heat. Overall, I'm satisfied with the service and outcome.

The technician arrived promptly, fixing our heating issue just 30 minutes after being called due to a sudden power outage in mid-January. Office staff member Jessica was efficient with scheduling and kept us informed about Chris's ETA. We'll definitely be calling them again in the future; thanks for the great service!

We hit rock bottom on a chilly Sunday night - the coldest of the year so far. Our furnace decided to stop working, leaving us in a panic as new homeowners often do. I called your company at 7:30 PM and was met with someone who kept me calm despite my distress. They explained the emergency service fees upfront and promised a technician would contact me soon. From that initial call to having our heater fixed, everything moved swiftly and respectfully. Kudos to this great team for turning an anxious situation into a smooth one.

The technician Jerry was very professional and knowledgeable, impressing me with his work. The company's prompt scheduling was a big plus, getting everything done in just two days. I'll be using them again for any future needs without hesitation.

We hired a contractor to fix an issue in our attic. They came out, gave us a quote, and did the job the same day - very impressive. The technician we met was courteous and did a great job. We're extremely satisfied with the service and would definitely recommend them to others.

Tony quickly diagnosed the issue with our furnace and got it up and running fast. He was courteous and friendly during his visit. The technician took the time to explain the repairs, ensuring I understood the work done and received value for my money. He also provided helpful tips on maintenance and inspection to help me anticipate future needs.

We needed a new furnace, and this company came through. The installation was prompt, and the technician doing the job was top-notch - as were all the others involved: the ones coming out to assess the old unit, the rep on our initial call. They got it done right, and now my family's warm again.

Illiana Heating is top-notch - they're very professional and always get the job done. The tech, Jim, was particularly great, very tidy and patient. I've been using them for years and can confidently say their service hasn't wavered. Their recent visit was a furnace check-up.

I got lucky with a free furnace maintenance promotion from Illiana Heating & Conditioning, and it was worth it. They scheduled me for 8:00 am sharp and showed up on time. Chris L came over and gave my system the full hour it deserved - cleaning, inspecting, and replacing filters that needed it. With winter being super cold this year, I can breathe a sigh of relief knowing my furnace won't leave me high and dry. The service was top-notch, and I'm looking forward to when they do mine for air conditioning too. Illiana Heating & AC is the way to go - don't hesitate to give them a shot!

We replaced our 20-year-old furnace with Illiana Heating and Air Conditioning, Inc., opting for a bundled package that included both air and furnace services. Misha handled the furnace installation and Adam took care of our air conditioning. Both technicians were highly professional and did an excellent job. They answered all my questions and provided valuable insights into their respective installations. I'm pleased with their service and enjoyed doing business with them.

I've consistently been impressed with Illiana's performance over the years, thanks in part to my Gold Club membership. Their maintenance has always been top-notch, making it a straightforward decision to upgrade my systems through them when I needed new units. Dan did a great job of explaining everything and ensuring we had what we needed for the installation. The two installers, Steve and Adam, were highly professional throughout the process. Overall, I appreciate Illiana's commitment to their work and the pride they take in their company, which makes all the difference.
