The reason of the two star is the job that was done. I was expecting Midwest Heat & Cooling to replace my GE AC wire. The wire was completely cut in half by my puppy, thus the reason of hiring them. I paid over $200 just for them to tape the wires together. My AC unit still does not work and now I have an electrical hazard that I now have to deal with. 10/10 Friendliness 0/10 Reliability I do not recommend.

**BUYER BEWARE** The 3 different technicians that came to…read moreour home were all very pleasant and polite. Our heat went out and the first technician said we had a bad sensor and it needed to be replaced. He did not have the part on the truck, so he cleaned the old sensor and our heat worked. (The contractor we called for second opinion said it would be fine to run on the old sensor after it was cleaned and felt part replacement was excessive.) The Midwest tech also gave us multiple quotes for things that were not broken. Included was a quote to replace our two working thermostats for over $1,400 because they sometime draw more power when not wired properly...although he said ours were wired properly. He spent a significant amount of time at our home, apparently writing up the additional quotes that were not needed. A different technician came to install the part we were told we needed a few days later. He also spent quite a bit time at our home.... writing up some more quotes for things that were not really broken. These items were different than what the first tech recommended. Then our heat went out again a couple days later. Technician number 3 came and spent a lot of time at our house and told us we need to replace the whole control panel (Although, he was able to power the system on and off to get it to work). He also said the inducer motor bearings were making a grinding noise and needed to be replaced. Keep in mind neither of the first two technicians noticed a bad panel or the bad motor bearings. He also said that they are required to write up at least 3 quotes for each customer. Yes, we are trusting souls, but 3 strikes and you're out. We called another heating company. As mentioned above, they said they would have cleaned the sensor for us and would have been done. They also could not find anything else wrong with the system at this time. They suggested that we just call them when it happens so they can find any real problem. It saddens me that a company like Midwest appears to be training and encouraging these young men that work for them to find things that are not broken and scare customers into ordering that repair. It appears that they are teaching them to cheat, lie, exaggerate, whatever it takes to make more money. Definitely not a reputation I would want...I pray that Midwest develops some more honest and customer focused processes. If they did that maybe they would get my business.

I had not used Westenn before and wondered if any emergency service repair companies would be answering during the holidays. My call was promptly answered and a service person was on his way.

Westenn will be our new service provider and I can't thank them enough for the great after hours service and especially during a holiday weekend. Last but not least, the pricing was fantastic and so fair especially because it was a holiday weekend!

I called as soon as it was over thinking I'd have to leave a message for a call back in the morning. Nope. The owners wife was so friendly despite it being late on Sunday.

They got me in the next morning, diagnosed it right away, ran to get parts across town, and had them installed so fast it was spooky. I'm hesitant to trust heating and cooling companies, but was seriously impressed. They'll be coming back for a clean and check on my furnace and A/C unit this spring. Great job, Russ.
