I have been using this company since I moved into my house 4 years ago and have always received timely, professional technicians assess my HVAC system twice a year for routine maintenance. No question I have asked is ever too “silly” or strange and they will always provide answers that I can understand in layman’s terms . I would recommend them to anyone.

Alltech HVAC was amazing throughout my HVAC installation. From the administrative side with Emily in the office to working with John and Alex with the install. My new HVAC systems were installed seamlessly and work great. I also feel comfortable and secure if service is ever needed for the units moving forward. Alltech is very responsive and knowledgeable. I used them for repairs in my last home, which had a unique setup with a boiler, Spacepak and regular furnace system for the addition. There isn’t a system they can’t service. Strongly recommended!! Thanks Alltech!

An honest and courteous company. My son was out of town and their furnace went out in their condo. My daughter in law called Four Seasons to take a look and they gave her a price of $2000 to fix plus would have to replace their furnace soon ($$$$).

Based on the price she received it was recommended she get a second opinion. Alltech came highly recommended. They came out immediately and found it was just a switch and now the furnace is up and running. it doesn’t get much better than this. Don’t waste your time and money on those highly advertised companies. They saved $1700 by using Alltech.

I was referred by a Contractor ( Electrician ), I know who has worked with them on construction projects and said they were the Best !!! Alex was Extremely Knowledgeable, Professional and Polite. I was Very Impressed with how Polite/Professional the Office was when I called to make my first ever Appointment… My Navien Combi Boiler is performing GREAT !!!

Professional and knowledgeable. We’re happy with our new water heater

Prompt, knowledgeable and reliable professionals. Highly recommend them. Nicest people you’ll ever meet!

Great company with very responsive and knowledgeable employees! Would highly recommend to any one looking for HVAC Service, Repair or Replacement.

Great work and great service! Very reliable and will highly recommend them.

Our A/C went out and they were able to fit us in last minute! My service technician was knowledgeable and professional. Everyone I spoke to at the company was super friendly. I would definitely recommend them!

Alltech is the best HVAC company on the Northwest Side of Chicago, I used two companies before finding Alltech and I will never use a different company. Prompt service, extremely fair prices and no fee to show up to your house. When someone from Alltech comes to your house for a job not only do they do the job they came in for but also check on all the work they did for you in the past. Great people and a great company.

Super awesome guys to work with!! They worked fast and efficiently and the have great pricing! They have replaced units at both my homes. I highly recommend Alltech HVAC for your home.

Excellent service, good guys working for them. Attention to detail. If your looking a good company these guys are who u want.

Had a problem with my 40 year old boiler. John gave me two options to fit my budget. I compared him to two other companies and the value and service was outstanding compared to the others.

Great company and service. Needed an emergency AC call today, they arrived promptly and only replaced the parts needed. Highly recommended.

I recently had some water leaking from my radiator pipe from a previous repair clamp from the previous owner in my condominium. I contacted John with Alltech HVAC and exchanged information and a picture of what was taking place. He was professional and quickly was able to diagnose the problem and send a technician out (Caleb) to fix the problem, minimizing what could have been more water damage and headaches. It was a great experience during a challenging time and the rates were very reasonable. I’d highly recommend this company for any service needs that you may have.
Thanks again!!!

My experience with Alltech has been great! Joe and John are courteous, prompt, professional, and true to their word. They go above and beyond! I would be happy to recommend them to anyone.

Have hot water heat; there was a ‘gushing’ sound in the radiator. John from Alltech came out last Thursday and evaluated the problem, determined there was low water pressure in the system causing the noise and also a problem with the relay valve, which didn’t turn on.

He came back on Friday and installed a new automatic air vent and added a couple of more valves on the boiler so that if it does have to be drained again, it wouldn’t necessitate turning off the whole heating system to accomplish this.

I was very satisfied with the end explanation, and the solution applied to this problem and wouldn’t hesitate to call AllTech if I had another issue with heating or air conditioning.

Great staff and wonderful work. Alltech installed a new furnace and tank-less water heater in my home. Great craftsmanship for the price. You will not be disappointed!

Friendly and Reliable! Alltech HVAC has some of the smartest technicians I have ever met who solve problems quickly and accurately which saved me money!
