They sell you furnace/AC system with 10-year warranty, but they don't register the warranty as 10…read moreyrs from manufacture, so they don't honor their warranty when you have another contractor come and replace the part. Come to find out they never filed paperwork with manufacturer to honor 10-yr warranty, so manufacturer shows you only have a 5-yr warranty. Won't reimburse you either for that part under warranty. Wonder how many other customers think they have a 10-year warranty on parts, but Just in Time heating never properly filed the warranty with distributor/manufacturer? There is only one distributor that handles local area for parts, so all contractors use same distributor. Furnace heat exchangers and compressors should have a 20 or 30 yr warranty after talking with other contractors, but Just in Time heating offers 10 years. Any contractor can do warranty work if the part is warranted. Reason another contractor did the work is, Just in Time heating charges are double, they say a part is not under warranty when it should be under warranty, want to tell you other parts are bad but when you have another contractor come out for second opinion, that contractor says that part is working just fine. Charged $180.00 to replace a 5-amp fuse that cost pennies to replace on the furnace, took maybe 5 mins to remove cover and replace fuse then put cover back on. Just in Time Heating always tries to sell more than what is actually needed. Charges to come out and look, charges for installation fees, charges for part that should be under warranty, Wont honor the warranty. Do NOT do business with Just In Time Heating from Sandwich, IL.

My moms furnace failed the week before thanksgiving and the service that came out to look at it…read moresaid they had no time to do it and I needed to call someone else. I called Jon from tri county heating and he was able to fit us in between appointments that same day to assess the situation. Despite being super busy and a challenge with finding a new furnace on short notice, he was able to get us up and running in two days. He could have sold us a larger furnace same as we had but he indicated that we didn't need such a big one and saved us some money. With my Mom being 85, It's reassuring to know that we have found someone we can trust and who will be responsive. He even lent us some personal space heaters for the days we were without heat. That's service. I can't thank him enough. Highly recommended.

I am giving Tri-County Heating & Air five stars. My furnace quit working properly on one of the…read morecoldest days of January and Jon heard my concerns and promptly showed up. My furnace was letting off toxic fumes and he stayed with me until he was certain all the air was non-toxic and I was safe. He then proceeded to make sure I had a brand new furnace the following morning and was prompt and on-time. Not only is he knowledgeable, but he went through everything with me so there were no questions. Him and his co-worker were clean, orderly, knowledgeable and helped put me at ease. I am a sales professional and I know bull when I see it. These guys are on the mark and I would refer them to friends and family. I will definitely call them again for any work related to my heating and air. I owe Jon a lot for helping me out of a bad situation.

Stay away from this business! My entire cooling and heating system was left in an inoperable state…read more I called for a diagnostic of the air conditioner today because cool air isn't coming from the vents. I was told the diagnostic would cost $149. I asked to be informed of any repairs that had to be done. Technician checked the system and recommended replacing unit. We discussed replacement unit and cost. I was ready to pay deposit. In the next 10 minutes I was told that the model I selected is old and not available. New model costs $1000 more. I asked for a proposal to decide later. Technician told me that the visit costs $396. He said that he fixed air conditioner that was not working. He never told me that he is fixing anything. Through our the visit it looked like he was figuring out the problem. I talked to the owner and we agreed that any repairs that were done will be undone so that I do not have to pay for repairs. Then the technician removed all the wires from the board making both heat and fan unusable. He did not just undo the "repairs", but made entire system unusable including fan and heat which were working before his visit. See the photos to show what was done!

Reply to 2 reactions from Harmonic on my 1 star review…read more 1. A. & K. claimed A. fixed my heater Tuesday; lie. Bad customer service. Harmonic deserves 1 star, but all the starts below 5 are NOT indicated on the Google graphic of the numbers of review stars 1-4: false. 2. I never promised a review pull-down for a discount. My husband & I have better things to do than having an "agenda" as Harmonic accused. My husband was on a business trip. 3. I never called for an emergency repair. I did not switch from repair to cleaning & maintenance. I asked A. if C & M was possible afterward, unaware of 2 more with no heat. Harmonic called me "selfish" for this. 4. Any possibility A. and K. have unconscious biases towards people like me? They accused us of "manipulating" what? To save a few hundred bucks, while we spent in the tens of thousands at Harmonic's better former (aquired) company) you imagined up? 5. How could Harmonic accuse me of lying about my pain. Because I was able to and had to carry my 10 lb dog for a short moment because of her barkin? Why do I even have to explain my chronic severe back pain and mostly failed back surgeries and weak immune system? 6. I had no "agenda," but getting my heate fixed. I am not playing any "game" as accused. I am standing up for myself. 7. K.'s statistics on the number of my Goole reviews are false. 8. A. & K. are the ones who were "aggressive, harsh, unethical, disrespectful, and manipulative." Stop projecting and gaslighting. I wish I would remember to record conversations when I am alone with a person like A. Why did K pull down his absurd replies on Google?

His first question was why did I think I need a new one?. My reply was because the storm took it out and it must be damaged. " I can fix it if you wish, it is your choice" Within 10 minutes the A/C was running and he was giving me hints on how to take care of it. Most would have taken my word for it and begin giving me a price for a new one. Not Frank. His honesty saved me $3000 dollars or more. I will not be forgetting his honesty or his professionalism.
