The technician called me back immediately and stopped by us on his way to another job within 30 minutes of the call.

I am happy to be working with a small, local business, and now I'm never turning back. Thank you Williamson!

STI Heating & Air Conditioning saved me so much money! I had another HVAC company looked at my…read morecentral air unit because it was blowing lukewarm air. The other company told me I needed a new compressor for $1699 and they took only cash. After a repairman ran off with $453 of my aunt's cash, I decided I did not feel comfortable giving the HVAC repairman $2000 (with labor) in cash. So, I told him I would seek a second opinion. I called STI Heating & Cooling who were booked for the week so I made an appointment for the following week. Ted arrived on time and was very professional. He took a look at my unit (which is 42 years old) and told me I needed a Hard Start Capacitor for $173. He also checked the amount of Freon (R22) told me I might need a little. He installed the capacitor and added a little Freon and my unit start blowing extremely cold air. Ted's work was great! He told me his father had an old unit like mines and he keeps him father's unit working. I told Ted the other repairman thought I needed a new compressor and Ted suggested maybe the other repairman was not familiar with older units like mine. I am SO glad I called STI Heating & Cooling! I told Ted they are now my go-to company for ALL my HVAC activities. I would highly recommend this company - they proved to be a huge money saver for me.

We had just moved to NW Indiana and bought a home. The air went out within 2 weeks of us closing on…read morethe house. The home warranty wouldn't cover it. Our neighbor recommended Mark Collins and his company. The store opened Monday at 7. I called at 7:15. Mark ( the owner) answered the phone. Owners answer the phone? I love it! He was very sympathetic to my needs. He apologized and said he couldn't get out there until 9:30 am that morning! That's a window of 2 hours! Dont apologize Mark- I'm beyond happy. Mark showed up as promised and gave a quote for a new unit. He wasn't pushy and he didn't try to oversell us with a larger more expensive unit. He left pamphlets of models for us to look at. We called Mark back that afternoon- we decided to have him install the new AC unit. Again, he was apologetic. He wishes that he could install it that day- but couldn't. Instead, he could install it the next day- Tuesday. He said he carried that unit in stock. As promised, Mark and another man showed up on time in a company van. They removed the old unit and installed the new one in a timely fashion. He went over all of the features of the unit and showed me what he removed and replaced. They were quiet and neat and didn't leave a mess. We turned on the AC unit and we had Air conditioning. The unit is purring like a champ! A few days later, we get a "thank you card" in the mail from Mark and Collins Heating and cooling! Who sends out thank you cards anymore.... Collins heating and cooling does! This is a very small personable company that can tend to all of your needs- night or day. When our furnace goes out- Mark will be replacing that unit too!

Needing a new furnace and A/C, I took one week to get estimates from 6 different local companies…read more Jason was the last one to cone out and he was the one I went with. He is a technician, not a sales person like most of the other companies. Therefore, he know what he was talking about as far as what equipment I needed, and why. He was very personable, polite, and an asset to the company. I decided on Modern and scheduling was only a few weeks out. On the appointed day, Jim and Dave showed up on time, and worked all day to get everything installed. They were polite, prompt and obviously knowledgeable. All went without a hitch and they removed the old furnace and AC and cleaned up everything before they left. I certainly chose the right company, I could not be more pleased with them and how flawlessly everything went. Their price was the best around for the very same products other companies quoted considerably more for. Please shop around and do your research before you make this considerable purchase. I did......and happily, I chose Modern!
