5.0 Jeff S. Elgin, IL

I have been very satisfied with Lasco Heating & Cooling. They have been maintaining and repairing my finance and air conditioning across multiple properties for over 10 years. Keith is a great partner, giving information on how much useful life on parts to help me decide what to replace to prevent emergency service calls. Keith is very responsive and repairs things quickly.

5.0 Ryan B. Mundelein, IL

After a few years of using other heating and cooling businesses I found Keith, he was always on time and ready to work. We had a few issues with our boiler system that was getting up in age and he said he could fix it but it may only last a couple years so we decided to just replace it. Keith gave us a great quote and was again prompt and thorough on installing the new boiler. We were so happy with him that when we needed AC work he was the first one we called, which we ended up getting a new AC unit as well as it was old and could have been serviced over and over again but now the new ones are more efficient and almost pay for themselves. So when our water heater went out there was only one person to call, Keith was here as usual, quick and clean and no issues. Now we call and have both serviced regularly by him and no more problems and can rely on his work to keep us comfortable in our home. Call Keith if you donâ t want to worry about your homeâ s systems you wonâ t regret it.

I needed to check more services than I was able to. I highly recommend Keith. He has replaced our boiler and hot water heater. He also services these units every year. He also replaced our plumbing in our remodeled bath and kitchen. He has serviced our AC units which is very old and need to be replaced but he has kept them going for us for quite some time until we are ready to replace. Which when we are ready we will use him to do this. He is a full service mechanical technician that is trustworthy and very fair priced. We met Keith through a recommendation and that was the best recommendation we have ever received. We have been using Keith for close to 10 years and itâ s great to know that if we have a problem with anything he will be there for us.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
