Ish and his crew were very professional, friendly, hard working, and with very reasonable in pricing. The installation of my furnace and humidifier was done carefully with explanations of the process. The gentleman finished with cleaning up all of the trash. Thank you Best Rates Heating and Cooling. Great job!

Random morning last week we noticed air in our pipes while showering.Checking the basement we found the water heater leaking. Not knowing when it could burst I immediately reached out to Ish and within minutes he returned back and instructed me on what to do over the phone. I didn’t expect a replacement that day as knowing Ish is very busy. That night he actually had a concert for his daughter at school to attend but he still stopped by after his schedule for that day just to see what parts to get along with a new water heater. He pulled the other one out, cleaned up and got organized for the install. What is different about him is he cares and knows his customers and their families and understands all needs. After his daughter’s concert Ish came back and did the install and was at my home well after midnight. Can’t express my gratitude. Thank you

I called at 8:52 PM to offer them a website because I noticed they’re using a free website with no proper domain — something that seriously hurts credibility. The business is listed as Open 24 Hours, so I figured they’d appreciate the heads up. Instead, the guy answers and says, “Do you realize what time you’re calling?” followed by “What kind of business strategy is this?” Seriously? Maybe the better question is — what kind of business strategy is running an HVAC company in 2025 with a free Weebly-looking site that doesn’t even work and snapping at people trying to help you fix it? If this is how they treat someone offering value, I’d hate to see how they treat paying customers. Definitely not the kind of mindset I’d want in charge of my home systems. Stay away.

Fair price from a dead-honest dude. Lots of communication and check-ins all throughout the process and quick clean work when installing. Also partnered with a reasonable and easy to work with financing agency. After the full overhaul they did I hope to never need HVAC help again in my life, but if I do I'll definitely be calling these guys.

Ish did an amazing job. Knew the problem rt away. My ac unit wasn't working and he came to see what was wrong. He didn't have the part that day but tried to see what he could do to get it running until he got the part. Got the part the following Monday worked until after 10pm to get it done so my family could have ac again. Would definitely rehire and recommend him to anyone!

I needed a new air conditioner for this coming spring and summer I had a couple companies lined up to come to my home here in Bolingbrook, from Best rates heating and cooling from Oswego came out with his daughter, and he noticed that the furnace was giving issues. He asked me if there was anything going on, the amazing part about it is I went down with both of them even his young daughter who is nine years old asked his father and said hey Papa, the furnace is not supposed to be making that booming sound right thatâ s when I knew that I was gonna be going with this company for his daughter to know at such a young age how a furnace should operate he responded with. Itâ s not operating well but weâ re going to figure it out. Keep in mind I had called him for the air conditioner on he checked the age of the unit and the brand-name and he brought me up to speed. My unit was 14 years old after he said what was causing the booming sound was that I had a flexible gas line and he said that he would repair it for me. He also went above and beyond and check the inside of the furnace and the condition with his camera and I saw that it was rusting up in the inside. His professionalism was great he said we can continue to the just AC If you would like to, but you may only have a couple years left. He gave me both options for both. I went forward with him. Right away You canâ t shop that type of customer service. The morning of the install it was raining I thought to myself maybe they will reschedule Shirley enough. They showed up at 7 AM at my doorstep ready to rock â nâ roll. Ish and General Sir good morning and put down flooring cloths and they continue to do the install even in the rain. These guys worked hard and Iâ m excited to use my new Wi-Fi thermostat. They even help me and was patient enough to set it up the WiFi thermostat because I forgot the password and the installation is Came out perfect way better then I expected. Definitely recommend them.! Ask for ISH!!!!! Thanks guys

Ish Medellin (Owner) is very professional and knowledgeable. My furnace was running but not blowing hot air. He arrived within the predetermined time slot as promised. Was extremely thorough with explaining the issue (needed maintenance), identified the product that needed to be replaced at a reasonable price. Due to my health condition he recommended a product identified as an Air Scrubber. Itâ s purpose is to remove impurities from the air; and, improve the overall air quality within my home. I would highly recommend contacting this company if you have any HVAC issues. Overall I received amazing customer service. In addition pricing was fair and affordable.
