Air Source 1 is one of the most thorough professional businesses we've ever worked with. We called to have our A/C cleaned and they came out the next day. After Jake cleaned it he noticed the coil kept freezing. He stayed almost three hours to try and fix it. He went way above and beyond what we hired them to do. After considering our home warranty and how long it would take to replace/fix the unit we decided to call them back and have them replace it. I called Tim on Sunday and he was able to schedule the appointment the next day. Al and Luka came out right at the scheduled time and completed the work, again, thoroughly and professionally. Air Source 1 is definitely the best in the area. They do what they promise on time and efficiently. We will be referring them to everyone we know that needs HVAC services. read more

Quick call back. Very knowledgeable and thorough. Friendly and professional service. Gave me a fair and honest estimate and did the work as promised. I've had other contractors in past do work and I've finally found a good, local place to call to get work done. Thanks Tim! Your guy did a great job and he even cleaned up after himself even after my wife told him not to worry about it, lol! I will definitely call you the next time I need work done. Thanks again! read more

95°...AC broke down, called Tim from Air Source 1 on Monday. I expressed that I thought the condenser fan motor was bad, he didn't hesitate and explained it might be something like a capacitor, $800 for new fan, $225 for new capacitor. Tim came over first thing Tuesday and fixed it. Entire bill $275... nice and cool now. Thanks Tim, great job! read more

Quick estimate, listened to what I wanted for equipment (heater & a/c) and came back with a great price. Installation was done well, and all work/mess was cleaned up before they left. read more

Tim, Jake and team are fantastic! I interviewed 3 different companies to install my new AC and furnace and I am so glad I chose Air Source 1. Prices are fair, Tim is very responsive, and the install team was on time, friendly and very knowledgeable. I highly recommend this company!! read more

THE BEST HEATING & AIR SERVICE I HAVE HAD YET!!!! This is my second home in Frankfort & this is the 6th company I have used in the last 10 yrs. My husband & I will look no further & either should you! We always call a different company due to response time, service, price & actually quality of work. We would love to have consistent company to use but just never had anyone that great. My first home I was a young & single female, I had very little knowledge of the care & mechanics of a furnace or AC. So now looking back I know at times they kinda took advantage of that or were condescending toward me we I had issues &/or questions. My AC went out on Thursday evening, & Tim from Air Source was out at my house before noon Friday! I could tell immediately he was different than the previous service guys who I've dealt with before. He was easy to work with, patient & great prices. My husband & I can also really see that he takes a lot of pride in his work. He is not trying to just get in & out for the money, or at all pushy to make a sale. He explained things to me, spoke with my husband on the phone since he was at work, & gave us our options. Then when his team came to do our new condenser & Acoil install they were nice, respectful, patient & clean. They ran into some unforeseen issues & never got discourage or frustrated. I assumed to be charged more for the problem they had but Tim is a man of his word & still did the job for the originally quoted price. We were super impressed & incredibly thankful for his generosity! We much rather give business to individuals from our own community any day. But hands down To someone who values growing & building their business off of quality work & service. We finally found a stand up business that we can depend on for years to come! If you are in need of any work big or small we highly highly recommend Air Source 1. Thank you so much to Tim & his team for getting us out of the heat! read more

Highly recommend! Came out same day as calling. Reasonable priced and was able to repair my air conditioner. Will definitely will use again!

Tim is AMAZING with his pricing&work ethic! I was so fortunate to have found him when purchasing my first home! He's quick to respond, mannerable, gives service advice&performs above and beyond the work that needs to be done! Give him a call&see for yourself! This company will continue to have my patronage! read more

Awesome HVAC company!!! Our A/C went out one day and I looked up HVAC companies to come out and diagnose. Called Air Source Jake, the due to their great reviews on Yelp. Jake, the technician came out the next day to diagnose the issue with our non-working A/C. Jake was pleasant, very thorough, and explained our a/c issue situation in detail. Unfortunately, our a/c was old and shot and had to be completely replaced, but Jake gave us a reasonable quote on a new A/C. However, because I just don't like to go with the first quote or resolution someone gives me, I had another HVAC company come out without mention of Air Source 1 coming out. This second agency diagnosed same issue and told me too that my a/c unit had to be replaced. The quote I was given was above Air One Source and the warranty for labor was about 4 years less than Air Source. So I decided to go with Air Source because of the professionalism, the accurate diagnosis, the most reasonable quote, and the awesome warranty. I Scheduled Air Source 1 to come out the following week. The job was done in under a couple of hours and now I have a better functioning A/C unit with a great warranty to keep me worry free for the next few years. read more

My AC went out a few weeks ago. First company I called said they knew what was wrong. Low on freon. I just wanted it to work for my elderly dog. Said company came out and loaded the freon and said there were no leaks. The next day, $600 dollar later, the AC was blowing warm air. Called them back and they pretty much said too bad. After much anger I started calling other companies for a diagnosis to see if the AC was leaking. The temperature outside was around 90 degrees and high humidity and every company I called was at least a week out to come over. I spoke to a guy I work with and he said hey, you gotta call Air Source 1. They saved him so much money and all that. I pulled the trigger and called. Tim said he'd be out whenever I needed. I was at work at the time so he came out the next day and said the outside unit and the evaporator coil needed to be replaced. Here's the hook, that same day before Tim came out another company were nearby that I'd called previously and they gave me the same diagnosis. This company was going to charge me alot of money for this. An hour later Tim showed up, looked at the unit, went in the crawl space and looked at the coil, came back outside and quoted me $1200 dollars less than the other guy. Plus the other guy said it couldn't be done without replacing the furnace!! Tim said that's not true. Folks, forever I would recommend Air Source 1 as your new and forever heating and cooling service. Not too many companies are honest like these guys anymore. read more

Jake and Luka did a great job installing a new hot water heater for me. Great service from Air Source 1 again!

Within two hours of calling, we had our AC up and running. Great service. Tim was professional. Looking forward to using this company in the future. read more

Called AirSource for a second opinion after being told by another company that the A/C compressor had failed and that I should just replace both the A/C and heating units at the same time. Tim came out and the system checked out fine. Added alot of freon and 1 week later the system is still running great - ice cold! Great company with a great owner! Thanks Tim! read more

Fantastic company to work with! Quick response, accurate estimate, and the work we needed was done well. And the communication was excellent. I highly recommend. read more

Tim is great! I highly recommend Air Source1! Our AC went out on a Sunday night, before the expected hottest day of the year. Moving here from Chicago, we had no clue who to call to get the unit fixed...QUICKLY! We stumbled upon Air Source 1 and called. Tim not only answered our call late Sunday night, but scheduled to come out at 9am the NEXT DAY! He arrived on time and was done within 20 minutes. He was very nice, knowledgeable, and very dependable. I was shocked at the low cost of his service. What a great, local company! We definitely will be keeping Air Source1 in our back pocket. If you want someone dependable, great cost, and efficient, call Tim! I was so impressed and we were extremely pleased to find yet another local, independent company! read more

Will never go with anyone else again. Replied back quickly and came out on the Holiday weekend to fix our air. Great job, price(did not over price for holiday), and fixed are air in a quickly manner. Texted and called he was on the way, friendly and told us what was wrong before he came. If you need heating or air call this place you will not be sorry. read more

Very timely response through Yelp. Tech who came out was great. He asked all the right questions, made sure he wore shoe covers in the house, and did his job in a timely and professional manner. Couldn't recommend them more! read more

I called this company after I was told my AC and Furnance was in trouble and needed a new one for 16K. Tim came out and looked at the unit and laughed. He knew right away what they tried to tell me was wrong and how he tried to decieve me. He said that the unit is in great shape and should last many more years. He didn't even try and sell me a new unit, which is the reason I asked him to come out. When I pressed he said if I really wanted it he could do it for under 7K, but I really didn't need it. Tim was prompt, honest and took the time to show me what I needed to do. I will never call another company as Air Source 1 is the only one I will call going forward. I will recommend this company to everyone who asks (and even some that don't) Great job Tim read more

Furnace went out a 3 in the morning and had a new one installed by 2 in the afternoon. Tim and his crew were professional and courteous. We are very happy with their work. read more

Awesome Customer Service and fast estimates for replacing a complete HVAC system that was 35 Years Old. My mom and dad live in Orland Park, IL and were pretty close to the Frankfort Service area. Contacted Tim and explained that my dads home AC and Furnace were failing and costing money recharging the AC compressor each year. Tim was able to meet my dad within 1/2 hour and provided a quote. My dad had a quote or two from several other companies but he felt that Tim provided a better and complete estimate than the other companies quotes. Tim said he could install both a new furnace and an AC 3 Ton compressor 36 hours after the quote. Tims team were out as promised and arrived at 7:45AM. Air Source 1 had purchased the new HVAC system and were ready to go. My parents house had just had the carpeting cleaned this year and so Air Source put runners from the front door, all the way to the basement. They installed and charged the system and tested the new furnace within 6 hours and installed a new thermostat. The whole team was totally professional and courteous. My dad, who is hard to satisfy, was totally impressed, and he told me that the whole house looked like no one had ever been there to do such a big job. Our thanks to Tim and his team at Air Source 1 !!! read more

Our AC went out in 90 degree weather and we are in a condo on the second floor! It's always nerve wracking when you need a repair on a big appliance. I couldn't have been happier with Tim! After replacing the capacitor and a cleaning, we have our AC back! Great job Tim! And he's a very friendly guy! Will definitely recommend him!! read more

Tim serviced our A/C unit for our seasonal PM. He was quick and very professional. I definitely recommend him and will continue to do business with him for future HVAC needs. read more

This review is way over due. We first called Air Source 1 last summer, 3 days after moving into our house. The air conditioning was not working and it was 90+ outside. They arrived the same day, filled the Freon and got us up and running again. We just used them again for our yearly maintenance on the furnace. Extremely prompt, professional and honest. Will recommend to everyone!! Thanks again! read more

Rating changed to 5 stars since Tim offered to send a check for 3% surcharge. While I will not accept the check, I do appreciate the offer. Another example of the excellent service received by Air Source 1!! I have always received excellent service from Air Source 1 regarding my central air conditioning unit. I guess I have always paid cash - the cost was always under $200. So, naturally, I requested a quote when I needed a new hot water tank. While the $975 cost wasn't the cheapest, I gave more weight to the excellent service I had received in the past. Even though I asked which credit cards were accepted, Tim never mentioned there would be a 3% surcharge. As a matter of fact, I wasn't told about the 3% surcharge until I went to pay for the water tank AFTER the installation was completed. It would have been helpful to know this in advance so I could have compared prices on a more realistic basis. Since I generally do not pay for anything over $300 without the protection offered by credit cards, I will definitely ask ALL merchants if there is a credit card surcharge BEFORE I agree to the purchase in the future. read more

Tim and his team are fantastic!!! I called them because my new furnace installed in 2017 kept shutting off. I thought it was my old thermostat. Tim went through extensive measures troubleshooting to find the cause of the problem and promised me that he and his team would resolve the issue -- no matter how long it would take. Air Source 1 discovered a plethora of problems. For one, the furnace is too large for my home which causes the furnace to overheat Hi and shut down. Tim also discovered a CO 2 leak in my home due to faulty ductwork that the individual who installed the furnace should have checked. These guys are so dedicated to their customers. They corrected as many issues as they could -- especially since they did not install the furnace. Tim even gave me a price on a new Rheem furnace -- which I thought was very reasonable. They corrected all the duct work issues and made sure everything was properly sealed, installed new gas valves, installed a new filter tray and a new thermostat. Tim recommended that I keep the furnace at no higher than 73 degrees or the furnace could shut down. Furnace is still running okay since they left my home on 2/5/18. I would definitely trust this company to install a new furnace in my home. Thanks guys!! read more

See all

I've been using Air Source 1 for about 5 years. I also found this company on Yelp. The reviews were all 5 stars, but if I could give them 10 stars I would. I've watched Tim grow his company during these past years and his dedication, knowledge, and dependability have never let me down. I have moved since I first used this company, and I have continued to use them in my new home and also my business. Thanks for your service! read more

I contacted air source 1 to install new WiFi thermostat, after few emails we set appt, Jake come on time and job was done, also helped set up account. Thank you read more

Our central air went out over the summer and we got several quotes to replace it. Not only did Air Source 1 match the lowest quote- but they were the only provider who alerted us that our heating unit needed to be raised off the ground to optimize the new units' full capacity. All the work was done on time and our new central air works great. Also- the owner is a nice guy- and very professional. The new unit cut our cooling bill in half. We highly recommend Air Source 1. read more

Last August, during a very hot and humid spell, Air Source 1 came out same day and fixed our very old and decrepit AC unit...we Yelp'd our satisfaction. We were told upfront that we would need to replace the unit in the near future, but this repair should get us thru the rest of the summer - and it did. Just this past July our AC gave out completely. We were very happy with Air Source 1 in the past so we called them and they came out quickly and provided a quote. FYI, we did our due diligence and shopped around, read reviews about other companies; and were very happy to sign a contract with Air Source 1. Jake and Luka replaced our entire HVAC system in one day and cleaned up the huge mess. We were happy to receive the warranty in the mail just a couple days later - along with a form to send to NICOR for an environmental refund. We really appreciated that Robin at Air Source 1 had already filled out the majority of form for us. read more

Had another company come out and told me I needed a new furnace and wanted to charge my an arm and a leg. I called Tim after seeing all of these positive reviews, for a second opinion, and all I can say is I'm glad I did. If your looking for honest, reliable, and knowledgeable people, Tim and his team at Air Source 1 are the real deal! Not to mention having a completely new furnace installed within 24 hours of calling! Wow! Thank you! read more

I wondered why all the 5 star reviews for this company. I had them (Tim) come out, and now I know. This company is all about honesty and integrity. My air stopped working - not blowing out of the vents. I changed the filter, which wasn't that bad as I am religious about changing it. I checked and re-set thermostat, turned unit off for 1 hour, then back on, still nothing. Tim came out the next day, and of course, it started working a few hours before he arrived. Even though it started working again, I wanted it checked anyway. Tim checked everything and found no malfunction. He did indicate it could be a hiccup with the circuit board. Told me to keep an eye on it and if it malfunctions again, check for an error and text him and let him know what it is. All I was charged was the service call fee. What is so unique about this is that I know that most HVAC service suppliers would have told me I needed a new circuit board, to the tune of a few hundred dollars and been on their way, and I would never had know the better. Air Source 1 and Tim are truly honest professionals, and I thank them for that. I'll use no other. read more

So excited to give Tim and his crew (Jake, Alex, Luka, and John) 5 stars! These guys are top notch in knowledge, service, work ethic, and respect. They replaced our old (30 y/o) a/c and furnace w/in approximately 6 hours w/o incident. One aspect of a good/great company is the workers and how they work. These guys seem to like what they do & work well together. We were pleasantly surprised when we heard singing from the bsmt from one of the guys & he sounded great! Call Tim and meet him - you won't be disappointed. He's down to earth and stands behind his work. read more

Air source 1 was excellent. They fixed my heat quickly and the price was right. I had another company look at my unit and they wanted to charge me $500 just for the gas valve and Tim was able to find out that it was under warranty which saved me a lot money. Great company read more

I was fortunate to grab Tim's attention when he was at a neighbors house. On a whim I approached Tim inquiring on some work that needed to be done. Tim was fast at fixing the issue, friendly and honest. I would definitely use him again and strongly recommend him to anyone looking. read more

AC went out on Friday night. Called Tim at 9pm, he answered and was at my house 7:30 the next morning. Half hour later we were up and running. Great work and customer service. If you want a quick response and the job done right, call Tim. read more

I highly recommend this company!Unfortunately our air conditioning went out last night, 93 degrees outside. Called the company first thing this morning. A wonderful man named Tim answered the phone and arrived a half hour later. Replaced a part.. Cleaned both air conditioners AND gave us a discount! UNBELIEVABLE SERVICE. THANK YOU TIM And AIR SOURCE heating and air!!! read more

I was very impressed with how fast they got someone out and had the problem fixed. A real pleasure to do business with and I will definitely be recommending Air Source One! read more

Furnace went out Sunday morning, prior to record cold temperatures being forecasted. We first called a very popular competitor who responded the same day and informed us that our heat exchanger was cracked and we would need a new furnace. They originally quoted nearly $5000.00 and then lowered their quote to 3700.00 and they offered installation within 48 hrs. We checked around and a friend recommended Air Source 1. We called them late Sunday afternoon and the response was immediate. I sent a photo of the quote I received to them and got a quote back on a comparable name brand furnace with the exact same warranty and efficiency rating for nearly 1000.00 less than the other guys. We made arrangements to replace the furnace that evening. They worked the install around my work schedule and arrived exactly when they said they would. They were polite, professional, and needless to say it was a tight work area. They were efficient, and cleaned the work area when they were finished. They stayed to make certain everything was operating as it should before leaving... all within 2 1/2 - 3 hours. I will never consider anyone else for my Furnace and HVAC needs. The price was unbelievable and the SERVICE was top notch. If I could give more stars I would. read more

I just recently had a problem with our AC and thought that it had finally gone out. It was working fine until about mid afternoon and then stopped blowing cold air. After some research and checking out the reviews online I sent a message over to Air Source 1. I received a quick response from Tim with some questions about what I had noticed, and to set up a time to check out the system the next morning. Before coming out Tim sent a confirmation letting me know when he was on his way and when he would be arriving. After talking to him he opened up the unit and took a look inside. It wasn't long after checking a few things that he was able to find the problem. A rag stuck in the blower motor which must have been left during a previous cleaning. Go figure. After making sure that the motor wasn't damaged he checked the freon levels and made sure the outside unit was cleaned. Tim was responsive and thorough making sure I knew what could have happened if I had left the system running, and what to lookout for in the future. I highly recommend Air Source 1 Heating & Air Conditioning for any heating and AC needs! read more
