Got a different company to come and look at it and I found out they installed an undersized unit in the house. So now I'm stuck with an AC that works as intended but is too small for my house.

My water heater went out. The company that "diagnosed" the problem charged me $99 and said that…read morethis did not include the cost to replace it. The company then quoted me $2200 as the cost to replace it and reiterated that this did not include the $99 that they already charged me. So yes, had I gone with that company, it would have cost me $2300. Armed with this information, I posted pictures and exactly what the "diagnosis" said and asked for emailed quotes...to be clear I said EMAIL only. I then got no less than 10 phone calls saying "please give us a call so we can talk about your situation. Some called more than once. Lakeland Heating and Cooling (Jason) was nothing like that... $1270 flat rate to replace the water heater. Yes, thats how he replied in his email.. as I requested. He came in.. with the water heater... replaced it... and went on his way. Other companies, that followed directions, also came in higher than $2000. I am EXTREMELY satisfied with Jason and Lakeland! High Quality, Tremendous VALUE

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

Hello everyone, I want to give an enthusiastic 5 thumbs up for Williamson Heating & Cooling. Let…read moreme tell you why, Williamson has been my HVAC team for 17 years. As a single girl, y'all know it's hard to find good help. Wayne and his dad are AWESOME! They've installed and maintained my HVAC system with consistent excellence. I once had an outdated furnace that would go out on the coldest days, Williamson has always been there for me. They arrive on time, clean up and are all very courteous. I have replaced a heating and A/C system with Williamson and there is no other HVAC team for me. I highly recommend my HVAC team. Williamson heating is the best!

I did get some quotes from a few companies but decided to use Addit Heating & Air Conditioning. They provided me with some quotes and also mentioned a special rebate that NIPSCO (the utility company in my area) had. None of the other companies mentioned this special rebate. Addit Heating and & Air Conditioning went above and beyond !! I was able to purchase the Seer 16 unit (their price was a bit less than what the other companies I got quotes from offered.) And the Seer 16 is much more energy efficient! The staff at Addit came out and got everything installed. Also they helped me with the rebate form I needed to fill out and submit to get the rebate. I highly recommend Addit Heating & Air Conditioning !!
