Chris was very professional and thorough in troubleshooting the issue. He got the unit back up and running, without needing to replace parts, saving us $1,500 from the previous quote. He also pointed out that coils were caked with dirt and debris on both units and needed a heavy cleaning. For an additional fee, he did for us helping to increase the life of the units. Chris finished with an overview of the services provided and shared an HVAC service plan they offer to ensure the furnaces and AC units run optimally. Outstanding service and thank you!

Which was amazing since we have been in a long heat wave, and I am sure they have been very busy fixing many AC units. He diagnosed the 2 problems that caused our AC to fail.

They were very personable, professional, experienced and knowledgeable about finding out what caused our AC to stop working. We highly recommend this company!!

Tried to tune the furnace anyway to accommodate it, which was actually kind of fun to watch all the different ways it could be done. No other HVAC technician I've ever worked with before has done that. A/C maintenance went great too. First company I've ever hired that didn't try to sell me an entirely new unit just due to a faulty capacitor. Even gave me the model number of the capacitor to replace if I want to save money and do it myself (I'm reasonably handy so it's something I'd probably do). I'll be using them for as long as they give great service!

My water heater went out. The company that "diagnosed" the problem charged me $99 and said that…read morethis did not include the cost to replace it. The company then quoted me $2200 as the cost to replace it and reiterated that this did not include the $99 that they already charged me. So yes, had I gone with that company, it would have cost me $2300. Armed with this information, I posted pictures and exactly what the "diagnosis" said and asked for emailed quotes...to be clear I said EMAIL only. I then got no less than 10 phone calls saying "please give us a call so we can talk about your situation. Some called more than once. Lakeland Heating and Cooling (Jason) was nothing like that... $1270 flat rate to replace the water heater. Yes, thats how he replied in his email.. as I requested. He came in.. with the water heater... replaced it... and went on his way. Other companies, that followed directions, also came in higher than $2000. I am EXTREMELY satisfied with Jason and Lakeland! High Quality, Tremendous VALUE

We used Krope and Son previously at our home in Lisle for annual tune-ups and again in our new home…read morein Naperville, including maintenance on our boiler system. Betty is always kind and helpful on the phone. Tim (the owner) and his son provided a fair quote for a heat pump and installed it last summer. Unfortunately, after it was installed, it stopped working approximately six different times and follow-up visits were needed. Water dripped onto our ceiling from the drain pan, and I had to have it professionally repaired. They finally got the system working. Did I mention this happened in the middle of the summer with a newborn? I decided to let the cost of the ceiling repair go, as I felt bad for them working on the system in the heat. In the fall, we decided to use another local HVAC company moving forward. They pointed out that Krope and Son hadn't installed the correct filter size, and had instead jammed an incorrect size into the new system. Now, one year later, it's been discovered that the drain pan was actually broken and siliconed together. I called Tim to ask why they did it this way, and he completely lost his temper, spoke down to me, and used the time to badmouth his competitor. Boy, am I glad I never filled out the sheets he had asking for recommendations to neighbors and friends. Guess they've lost our business for good.

Very responsive, quick to reply, great work every time. New ac and furnace installed in five hours.read more

Harmonic Heating and Air Conditioning is the BEST!!! Our AC…read moredied and after another company told us that our unit could not be repaired and had to be replaced ($6,000), we contacted Harmonic for a second opinion. Daniel the service technician opened the unit up and tested everything. He took the time to explain what he was doing and why. He discovered a bare wire that had been chewed (possibly by a mouse) and was touching the metal housing which tripped the circuit breaker. Daniel replaced the wire and the unit is working perfectly. The honesty and integrity of this company is refreshing. We will not hesitate to use them again and recommend them to all our friends.

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!
