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.

You begged for this review. I was going to keep quiet…read more I came in to purchase a simple 501 pleater filter. Clerk had a hard time checking our records. First she said was $90 then once she found our records she said it was $74. Then she couldn't check me out on the new software and had to use the old software. It took over 10 minutes to buy the filter. Then I said I wanted to talk someone about a price for switching my standard water heater to a tankless unit. She said it would be $6,540 without checking with anyone in the department or asking any questions about size or model or location or number of bathrooms. The company's switch to a money grabbing franchise model spoils the good name Illiana earned over the years. I don't intend to come back.

I was using my home warranty program, so JL Mechanical was assigned to me as their vendor. I had a new furnace installed and JL Mechanical kept me updated with the date of service plus text messages to remind me and give me a link to track my installation team members. They also email you a snapshot of those who will be doing the installation work. Robert was my guy and he was intelligent, patient, friendly, and answered all my questions. In fact, I've had repairs and installations done in my house before but the entire work area and my house was completely CLEANED UP when they were done. (I can't say the same about Comcast when they drill a hole in your wall) Everything is working great - it's been a few days now and I have HEAT - in fact, the new furnace is even quieter than the previous one and I can't even tell it's running. No more freezing nights wearing sweatshirts and ten blankets to bed!!! Thanks for the help and installation - I greatly appreciate the service, phone calls, and follow-ups!!!
