Talk about price gouging, charging for AC simple capacitor $300 and more, plus additionally service call and diagnosis!! RIDICULOUS!!! Capacitor anywhere for sale is between $10-15 , on Temu can get 3 for $10, even service technician said makes no sense, but has to charge what Siemer told them. Over 3,000 % price gouging, ripoff!!! Their excuse is not many people know prices!! read more

Called to get a quote from Siemer last year. I can't explain how professional the whole staff is from the quote to the appointment setting to the installation it was amazing. read more

I couldn't leave a 5 star review. Had good and bad experiences. My A/C stopped working and I call their 24 hr number. The 24 hr emergency service person that answer the phone took all my information but that was the last I heard from them until I called again the next morning only to be told they didn't call or show up because they didn't have me in the system that I needed service. After I gave them my info again, the service guy call me within an hour and was at my house with the next hour. this was great!!! It turns out my capacitor was bad. I was happy that it was the only problem. They charged me $355 for the Capacitor. (I thought that was a little high, even for an emergency call). Overall, I am happy the A/C is fix. I would still call them again for service!! I now have them in my contact list as my first choice to call for service. read more

On January 9th 2025, I was scheduled to have a technician came out to assess an issue I was having with a wall unit. The technician (Andrew) came out and determined that the gas valve was bad and needed to be replaced. I was told a service manager would be in contact regarding the pricing for part and install within a week. I never received the call so I called (1/16/25) and spoke to an agent (Cassidy) who said she would contact the service manager and call back. I never received the call. It's been nearly 2 months and still haven't heard anything from this company. I was charged a $85.00 service fee and told I would be receiving a receipt via email that I never received. I am extremely disappointed and don't recommend. I only gave two stars because the technician was pleasant. read more

I called Siemer as a last resort for our rental property in Hammond. I had an issue with the old 1906 Boiler not working properly. I had already had Lovings Heating and cooling and their tech didn't even troubleshoot just looked at how old and told me nothing could be done. Then I had Earls Heating and Cooling and they essentially did the same thing. They saw how old it was and didn't want to deal with it just suggest a whole new system in the thousands. When I called Siemer and explained my problem and told them this was my last resort they asked me to hold for a moment and told me I was going to speak with the owners wife. When she came on I explained my situation and she told me she would personally make sure the technician was the most experienced with Boiler REPAIR and he would do his best to fix it or figure it out. She said he would probably be really excited to see this boiler. Well he came out and explained that it is a bigger problem but he did clean up some of the connections and tried to make it work better. This is going to be a bigger problem considering the part is encased in Asbestos. These are all things I had a feeling about. However, whatever he did to service it and get it staying on worked and now my tenants have a warmer home now. I know he didn't have to do what he did but he cared about doing as much as he could and for now has given us some time to figure out the next step. Thank you Siemer. Your customer service is what customer service and dedication is suppose to be. CALL SIEMER THEY CARE......... and not just about money!!!! read more

I've found the staff of the family owned and operated Siemer Heating and Cooling company to be friendly, professional and they do what they say they are going to do. I highly recommend this company for anyone with a heating, cooling, boiler or air purification need. read more

The nightmare of installing furnace that was overheating could have been avoided if the air duct flow could have been double checked. But, in good faith Semier install the correct size furnace. Looking forward to see the start of summer our on new AC will starting up without any problems. read more

We called Siemer Heating for a furnace check after our warranty ended and the original HVAC company was closed for extended days near Christmas (beyond Christmas Eve and Christmas Day). We were very pleasantly surprised! The tech checked and cleaned EVERYTHING on this furnace! The original HVAC techs never did this thorough a job--NEVER! We will be calling Siemer from now on! FANTASTIC service, highly recommended! read more

Way overpriced. get estimates first, compare "oranges to oranges" They will try to sell un-needed services at inflated prices.
