We never felt like he was pressuring us or trying to up sell his services to make more money. I felt like he went above and beyond to make sure our central air system was safe. He was very knowledgeable, professional, polite, and efficient. I highly recommend hiring Kevin from JMS!

Showed up as scheduled, didn't do anything to fix it. "Diagnosed" the problem in 5 minutes charged…read more$140 for 10 minutes on site. Diagnosis was failure is eminent, yet no follow up and 10 days later pump fails and $3000 fix turns into $6000 fix. Promised a quote to replace faulty equipment in "a couple days" but 10 days and 2 phones calls later, no response. Was ghosted after making $140 for 5 minutes of work. Worst service one could ask for. Don't waste time calling to leave a message to not be returned, should have not paid until work started or called someone else. Now without water for dishes/showers/house maintenance until new pump can be installed with old well. due in part to promises made and not delivered. I should have paid the diagnostic fee and wait for the quote maybe it would have had higher priorirt, or at least been worth their time to communicate.

Appolo installed new furnace and central a/c unit in my home…read more At the time of the installation, the overflow preventer in the a/c unit was stuck, resulting in flooding my carpeted basement. The initial repair person who came to see what caused the flood was the one who told me that the overflow preventer install caused the flood yet Appolo refused to reimburse me for the insurance deductible. Two years later another (different) company came for routine maintenance and showed me that the original ductwork was poorly designed because there is a rule that there should be 24 inches between secondary ducts and the end of each main line; it is clear on most online descriptions that this is ideal for maximum air flow through the system. When Appoly did the original install I had them come back because the air flow felt insufficient and they told me it was by design because the goal is to run the unit for a long time at a lower air flow for consistent temperature!!

I have been dealing with them for over 20 years.

Electrician called and he came immediately. Thanks to Dave from Chiodo!!

Today (1/27/2026) we woke up to no heat once again. There are no repair companies in the area besides Chiodo (who don't seem to be able to get it working) willing to work on this unit and, based on the eror code, the the control board has failed so all I can do is replace it with a new boiler after only 3 years...would not recommend.

I would not recommend a company that deems a 19,000$ quote is appropriate for a simple 18,000-22,000 btu 2 head mini split. Wanted to add air to my 2nd floor as central air is sufficient for 1st floor of my home build in 1910. They said need new electrical service but even that would not account for some $19,000 quote for simple mini split. Way over priced! A brand new furnace and central air would not cost that much money. Should be ashamed to quote anyone that for a tiny system.

I asked if we could discuss a few things on it and the he kept saying he'd call but never did. I tried calling him a few times but eventually gave up. Part of their sales pitch is that they come out for emergency calls for their customers and how there's always someone available but if they can't even call me back to get a project started then why would I believe they'd actually show up when I needed a repair? Their quote was literally double the other quotes I had gotten and the markup on some items was ridiculous. The furnace model was listed on the quote so I looked it up and they were charging me nearly 5x what it cost. And it isn't like they were rolling in labor or other parts because everything was itemized. In the end, I went with a different company who did great work for half the price Halco wanted.
