      I have used King Heating for over 10 years at two different residences and they never cease to amaze me with their service. Over the years I have interacted with ***** ******** who helped me replace my furnace in January of 2024. He brought in space heaters for us to use until they could get there the next day to do the install and there was no pressure to go with them, however, they offered the best option for me and I was very comfortable with the zero interest finance option! The installation of the furnace and ac unit I purchased went very smoothly and I was more than pleased. I did have a few issues that I had to call about and they were immediately addressed and resolved. The technicians are always very professional and curtious. Since that time I have used their free plumbing assessment and found that my hot water heater was not only very aged, but that it was a hazard and required replacement. I again received top notch treatment. Pricing and options were provided and I did make a purchase. The installation again went very smoothly and I was very satisfied with the service.I recently interacted with ***** Springs for a quote to replace an old electric baseboard heater that is mounted into the wall in my laundry room. He provided me back quotes for the work which I waited on just a bit but decided to have done. When my regular ac service was performed by ***** *. We got talking about filters and the filter I was using vs what would be best to use and we then started talking about the filtration system that they offer. I was not aware of the filter system but was aware of the other items we discussed. At the end of the day I ended up having him call to have them add the system to my existing credit. ***** didnt start the conversation as a sales pitch and there was no pressure to make a purchase. ***** S was my install technician and was fabulous! I cant say enough about him. 5 PLUS STARS! Thank you ***** and **** for taking care of your customers!

      I had a tech come out to look at my furnace after a power outage on 1-15-25. He determined that the whole heating element needed to be replaced costing $1,100. I asked could the small part that wasn't working be replaced to which he replied no, the whole heating element needed to be replaced. I took all the info down because I was going to look into filing a claim with Comed. The next day they called saying they need to come back out and look at my furnace again. This time they said they can just replace the small part that wasn't working which is the thermal fuse or fusible link and they need to clean my evaporator coil or they won't give a warranty on the thermal fuse. The cost would be $759. I asked why was the cleaning of the evaporator coil not mentioned the first time and they had no response. How does a professional not know that the fuse could be replaced by itself and then they try to charge for another service that wasn't mentioned the first time. I feel like they were trying to take advantage of a single mom in the dead of winter knowing the temp was about to drop drastically in the next few days. I was disgusted with this company and would not recommend their service to anyone.

      Our Furnace was not working and after **** (tech) performed a diagnostic check, concluded that the heat exchanger was damaged and harmful CO2 would risk our home. He showed me digital pictures and after discussion it was determined that the furnace needed to be replaced. **** showed me options and instead of waiting until Monday for installation, he arranged a Saturday installation-no additional cost. ******* works great, runs very quite and were very satisfied.We have been King heating and cooling customers for over 25 years and they never disappoint!

      I called and was able to get a same day service appointment for no heat in my home. I had Alex as my Technician and he was great! Very knowledgeable and professional. This was the second time I’ve used King heating and cooling and plumbing And I will use them again.

      King is fantastic. If Costco backs them up that says a lot right there. My technician John H. was excellent and so professional. Explains everything with all the pictures of your system. Highly recommend.

      In the summer of 2024, I contacted KING **** on twice. The first one was on May 22nd, to remove the existing transformer and wiring, and to install a new transformer and necessary wiring. Also, test the system for proper operation. The service cost me ******. The second was on June 20th to replace a single-run capacitor 25+ mfd. This cost was ******. The total for these services cost me ******. The same technician ***** did these repairs. During his visit he started promoting a new **** unit for ******. He requested that I allow him to process my wife's and my credit scores to check our eligibility. I mentioned that I have a son in college. When my wife and I credit score was denied, he requested that we use our sons credit score. I'm uncomfortable with him asking me this question, and said no. During my conversation with him, he said that the repairs would fail. I asked why. He said the condensation of water would accumulated and cause the capacitor and cause it to malfunction. Then he insisted using our sons credit finance. When he checked the thermostat it was 84 degrees. After I paid for the service, the temperature went to 84 degrees. I called him and informed that his repairs did not work. He reiterated that he knew that the service would not work. I mentioned that he and his company must inform the client the service would fail before they do the work. That I should not be charged and the work should not have been done. I contacted KING on June 21st and complained the poor service and demanded a refund. Representative told me that a manager would be in contact. Later that morning ***** called me to ask what was going on. I told him the service did not work and requested a refund. He requested that we use my son credit to finance a unit. I insisted that he never mention that topic. He informed me that he would contact a manager and someone would be in contact on June 27th.

      Had them come out to give me a quote on a new Heating and Cooling system, after a week I called and asked for the price, and was told someone would reach out. After 2 weeks I reached back out and was told the same. Dont waste your time, if you need quick service. If you cant do the job, tell someone. Go with someone local not this company.

      DO NOT RECOMMEND, AT ALL. With the lack of enough characters to write out this complaint regarding the bad experience I had, I am forced to write in general of what occurred. In regards to the poor experience I had with this company today, (regarding 1 of the 2 jobs assigned for my house for today and next week), this company demonstrated poor customer service on the phone, extremely poor interpersonal office communication within the company, plus the inconsistency of each employee's lack of knowledge of required standard company policy regarding payments, job assigment duties and more, to communciate with me.***** (day's manager) and his employees didn't communicate with each other regarding the 2 air duct and air/heat furnace cleanings we needed for our house. Prior to today, (the morning of the job assigned), I've never spoken to *****. The morning of the 1st job assigned, ***** called me and was disturbingly rash, assuming and unprofessional towards me. Without speaking to me first, he demanded a deposit was needed before the day's job was to begin. When the original appointment was made a month prior, ***** at the company mentioned a deposit was required. The female employee said to me that I could pay the serviceman when he completed the job. (For the record, deposits are to be made in advance for jobs prior to the job date, not the morning of the job).After attempting to calm ***** down on the phone as he was still lashing out at me, he finally read her notes and admitted to me that her notes she had written, were not made clear and he could not even understand what she wrote. During the course of the day of the job, I communicated with 4 different employees regarding when the serviceman was to arrive (originally setup for 12pm-5pm) and each employee, including ***** had different answers as to what time the serviceman was to come, despite the original appointment made. I decided I had enough and canceled both jobs. Again, not recommended.

      Had my HVAC system replace JULY 2022 after my AC failed. My heat was fine before that, they convinced me to replace both because of the age of the unit. I've had some problems since having this installed. Since Winter when Temperature get 20 degrees or lower I have to run my heat most all day. I believe they installed under size HVAC for the size of my house. The last time someone was out ,Specialist ***************************. I was told they would upsize my system, that was about 1 1/2 months ago. Called for the last two weeks asked to speak to manager no call back
