HVAC reviews in Des Plaines, Illinois

I've been collaborating with this company for over 12 months, consistently receiving excellent results from their services.

Called Alltech on Sunday, central air failed at high temps (upper 90s) on Saturday night. Left voicemail on automated line; John responded within minutes. We tried troubleshooting for over an hour before calling them out, which got the issue resolved by afternoon Monday. Always reliable service and friendly staff.

Joe did a great job fixing my leaky furnace. Another company came before him and didn't find anything wrong after charging me $300 - they were there for over 3 hours too! All Tech was much cheaper and actually fixed it in under half the time. Joe got the job done quickly and efficiently, I'll never need to call anyone else again.

Joe consistently sends reliable technicians who complete the work efficiently. The technician's performance was excellent and I highly recommend this service.

We highly recommend this company for all HVAC needs. The staff are extremely knowledgeable and assisted us efficiently, resolving our problems promptly.

I recently had All Tech come to my new home for furnace and AC maintenance, which has been a lifesaver. The technician was courteous and extremely accommodating as a newcomer to the area. He did an excellent job and took the time to reassure me that they'd return once the weather cleared - no need for me to bother him again. I'm thoroughly impressed with this hassle-free service and look forward to having them handle my heating and cooling needs from now on.

They called back quickly and sent a technician within a day. Unfortunately, they couldn't complete the job until spring. Despite that, I'll likely reach out again in the future.

I've found Alltech to be a solid choice if you're in need of an HVAC system or maintenance on your current one. What sets them apart is their focus on customer needs rather than just pushing products. John, co-owner, is a seasoned expert who'll steer you towards reliable options. After having my old condenser serviced for several seasons, I decided it was time for an upgrade. The new unit with a heat pump installed is performing flawlessly. Alex, the installer, was top-notch - knowledgeable, helpful, and professional throughout the process.

As a small non-profit, budget is tight, but this company delivers. Their prices are affordable, the staff is friendly, and they show up on schedule. They even give you advance notice before appointments, which helps plan ahead. We've been with them for at least 5 years now and have no complaints - great value all around.

Chintan did a great job - he quickly identified the issue and presented himself with impressive professionalism.

I was thoroughly satisfied with the exceptional service and expertise displayed by this company's technicians.

The work was completed efficiently, demonstrating a high level of professionalism throughout.

Casper's visit was thorough, inspecting every component of my AC unit. He identified an old and rusty capacitor that needed replacement to prevent unexpected breakdowns.

I required a full replacement system for my mother's condo. I compared prices from several firms and Alltech offered the best deal hands down. They completed the job promptly and professionally, their technicians were also very courteous. That was about two years ago. We've since called them back for an air conditioning inspection which they handled quickly and efficiently once again. Overall, I had a fantastic experience with them and would strongly endorse their services.

I've been a customer of Alltech HVAC for years, relying on their consistent performance. Their technicians are always reliable, providing top-notch service with a professional demeanor.

We've switched to Alltech for our rental apartments and it's been a good choice. Their staff is polished, reliable, and efficient in managing tenants. Coordination is straightforward. Great service and value - would definitely use again.

My AC broke down in August and Alltech arrived quickly to resolve the issue. The technician was very pleasant and explained what caused the problem and how I can avoid it in the future. Their service is consistently excellent.

This company is reliable, showing up on schedule and being genuinely helpful. Unlike larger competitors, they don't try to push unnecessary sales pitches. I've used them for seven years now, sticking with their maintenance services for both spring and fall cleanings, including tankless water heater upkeep - a promise that keeps me loyal.
