I phoned Furnace Dr. on a very cold Friday night at 7pm. Sam G. came over immediately to look at my situation. Sam tried his best to obtain the part needed for my furnace but was unable to find one that would work in an efficient manner. He gave us sound advice and came back early on Saturday morning to install the necessary part after he was able to obtain it from the supply warehouse. He did a very nice job and was extremely courteous, friendly and efficient. .I will recommend Sam to my friends, family and relatives. He treated us very fair with the billing! ( Friday after hours and Saturday am). Very impressive! He is also dog friendly😊🐶

I called early on Monday morning to see if Furnace Doctors could come out and look at our furnace as it was blowing out cold air. I spoke with Sam who said they could come out to our house this afternoon. Sam called me to let me know that he would be able to come earlier than expected and asked me if that was ok with me. Sam worked diligently and quickly to get the furnace working again. I appreciate his professionalism and honesty and quick work to get our heat working again. Thank you again Sam and Furnace Doctors! I would highly recommend their services!

Sam showed up at the exact time he said they would. He and his apprentice were very friendly and worked well with me. They got me all cleaned and a new furnace blower all the same day, and at a very reasonable rate. I highly recommend them. I cannot believe how quiet my furnace is now!

Outstanding service! This is the first time in forever I have air blowing thru my east registers! I want to thank the kind, diligent and knowledgeable gentlemen that came to my house today! I still have a small issue, nothing on their part, but we were able to track it down and I am super confident that they will be able to fix it. I had a new furnace and a.c. installed from them last summer after my old a.c. stopped working in the 90 degree heat! Not only was the owner at my door within 30 mins. Sammy also worked with me on an affordable price! I highly recommend this company for all your heating and air needs! 👏💯

I had a problem with a faulty A coil leaking into my crawlspace. I called Sam at Furnace Doctors and he was able to repair it and replace my air conditioning system, which was badly needed. He is incredibly knowledgeable and friendly and explained everything he was doing as he was doing it. I will definitely use their services in the future and I highly recommend Furnace Doctors for any of your HVAC needs. Thanks Sam!

My air conditioner is about 30 years old. It quit Monday. Sam was totally awesome. He came and looked at it within a couple hours of my call. He was here the next morning and got it going again. He didn't try to push me into a new unit like some others have done. I can't afford a new one, (I wish!) I don't know what I would have done if he hadn't been able to repair it. I am so greatful and will reccomend them to everyone! They were so wonderful.

My A/C unit had been running excessively last summer and the bills had crept up, so I had the Furnace Doctors come out for a maintenance check-up on a warmer day during the Spring. The technician arrived when scheduled, inspected and cleaned the unit, and identified a component that was failing and that could explain the poor performance last season. We just had our first very hot weekend and the A/C unit was back to running for more normal intervals. Everything done was explained very clearly and the restored A/C unit's performance should easily cover in the first month the very reasonable cost of the preventative maintenance and component replacement. Highly recommended!

Professionalism is beyond expectations! This guy not only has all tools needed but doesn't wait to give you a response. He expeditiously handled my need, and most off all is his cool, calm and collective demeanor really made a difference! I would highly recommend him not just for his knowledge but every other aspect of how customers need to be treated. I've been in customer service for 30 + years and just have to say and give him 5 of 5 stars. Just want to give credit where credit is due! My one analogy I can come up with is when you feel secure with a getting your car fixed and find a gem and/or diamond in the rough which I could trust as a family member. Keep up the good work Sammy and any/every recommendation possible is what you get in return. Thanks again!

The furnace specialist named “SAM” was so amazing🥰. My mother and I did not have any heat on these COLD days and he decided to come right out. The way he worked it SHOWED he LOVED his job and cared about our situation. HE was not the NORMAL worker he SHOWED he CARED and we are grateful. We have HEAT!!!😁

I purchased a new home over the summer. I was chilly the other night and thought I would turn on the furnace to knock out the chill. Well, nothing happened. So I called Furnace Doctors and Sam came to help. My pilot light was out and it needed a cleaning and a new coupler. I was expecting the charges to be pretty high... But they weren't! If you need friendly, fast and professional service... Call Furnace Doctors!! Thank you Sam!

Furnace Doctors is officially my go to for any and all heating/cooling needs. When we started experiencing problems with our heating system during the winter the owner personally attended to those needs. He went above and beyond normal duties and even advised us on how to keep our heating/cooling costs low in the future. And since we have a home that was built in 1885 this advice and direction was indispensable to us. Sam is professional, courteous and thorough. He even checked back in with us a week later to ensure we weren't having any more issues. And if that isn't enough he followed up a month later to see how everything was going. This is the type of business which you can absolutely count on. I would hire them again in a heartbeat and recommend them to anyone that I know. Thank you Furnace Doctors!!

"Our a/c quit working on Saturday evening during a heat advisory for our area. I called Furnace Doctors and was told they were actually working in our area and could be at our house within 30 minutes. The technician, Sam, replaced the cooling fan motor in about 1 hour and 15 minutes. It was amazing that he had all the parts needed on his truck since our unit is 23 years old. The bill for the after-hours repair was very reasonable. He is our hero!"

"I was hearing a droning sound from my air conditioner in the kitchen of my house in Urbana. I called Sam of the Furnace Doctors in Champaign at 9 am on a Friday because I had used his services a couple of years ago, and he had done a good job. Sam showed up at about 1 pm and checked both the outside and inside A/C units. He found no problem, although he agreed that there was a repetitive sound in my kitchen not heard outside or in the basement. I agreed that we could hear the sound only in the kitchen. We concluded that it was an air duct or other part of my house that was vibrating at a certain frequency in sympathy with the outside compressor motor. Since there was no problem with my fairly new A/C unit, and Sam had not done any repair work, he didn't charge me for the service call. That was a great price for getting peace of mind that there was nothing wrong with my A/C unit."

"Sammy G. and company went out of their way to repair our tankless water heater. The problem was that the heater would shut down within a minute of running causing us to resort to cold showers. Sammy responded within hours of our call and returned to us the endless hot water supply to which we were accustomed. To top this, the bill was very reasonable. Consequently, I highly recommend Sammy G. and the Furnace Doctors."
