5.0 Debra G. New Lenox, IL

They were very efficient and patient!

1.0 Alexis F. Chicago, IL

For $90, I do not feel like anything happened. I was told I needed a new furnace. Felt scammed. Lesson learned. At least they came out.

4.0 Ruknul I. Chicago, IL

Good. I will recommend.

5.0 Angie G. Plainfield, IL

I highly recommend this company! We noticed a strong gas smell inside the house. We didnâ t know what to do! We called them and they came to check it out the same day. Told us the heat exchange was cracked. Francisco then explained our options and prices. We decided to Exchange the furnace and they came the next day! The temperature was below zero the day that all this happened. So I am grateful they work fast and got my furnace installed and running asap! I have little ones so this was super important to me. Thanks again!

4.0 Paul R. Downers Grove, IL

Appreciated how quickly they were able to replace my furnace. And their ability to work in freezing temps. Was a bit disconcerted by the installers lack of parts for connecting the gas line and wires. (Reducer and 5â nipple) but they did run to a hardware store to get what was missing. Would have helped if the first tech had taken pictures to let them know what to expect. The junior installer kept messing up the electrical connections which took time to correct. Wish they had not made such a mess of my floors tracking wet foot prints all over they must have made 20 trips back to the van to get parts and tools. But the main thing is we have heat again.

4.5 Ramona M. Bolingbrook, IL

Responded quickly, went right to work, provided some educated advice to prolong life of furnace, showed us the piece which needed correcting. Did not like paying cash with the promise receipt would be emailed tomorrow. Would have used credit card but they charge an extra 3% plus extra on a Sunday service call so I paid cash. Francisco was very nice and efficient. I would definitely recommend him to anyone.

5.0 Jeng F. Chicago, IL

This was for a multi unit furnace and partial duct work installation. Martin was the installer and on both days arrived on time and did the work. He even came back to resolve a blinking code that was occurring after the installation was completed the day before. I wish Martin would get some more help since he seemed fatigued toward the end of the install. It clearly showed when he cut a bit more off off the drywall for the return pipe for the second floor tenant. Overall I'd recommend this company.

4.0 Linda G. Indian Head Park Il, IL

They had some trouble squeezing me into the schedule, although my service call was not an emergency. I am satisfied with the service provided.

5.0 Jonathan S. Chicago, IL

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.

  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
