One Call Heating & Cooling
Heating & Air Conditioning Contractors in Crystal Lake, IL
Average rating: 5 out of 5 stars29 December 2021
“Brian and the guys over at One Call Heating & Cooling are the absolute best. I've used them since 2005. I really like how the techs have over 15 years experience and their pricing is upfront before the repairs. They are always really courteous and a pleasure to work with. They recently replaced my equipment after 20 years of service and their pricing was the best and I got a name brand unit I liked. I would recommend this company to all my neighbors, you won't be disappointed.”

CK Mechanical
Heating & Air Conditioning Contractors in Crystal Lake, IL
Average rating: 5 out of 5 stars17 February 2016
“I have used CK Mechanical on many different projects throughout our buildings for the past 3-4 years. The price is always fair, their attention to detail is great, they are honest, punctual, and reliable. They have saved us money by fixing the issues on older units rather than trying to replace them when not necessary. I would recommend them to any property manager or homeowner that wants the work done right at a fair price.”

Degree Heating and Cooling
Heating & Air Conditioning Contractors in Crystal Lake, IL
Average rating: 5 out of 5 stars23 May 2021
“Honestly, efficiency and reliability, a key part of self owned business that you do not get from larger companies. This is what John delivers for you. Stand back and watch the wizard work. John is simply the best around, very analytical and knowledgeable about his craft. He ran though his troubleshooting steps and took care of an issue for me within an hour. What I appreciate is he did not try to scare me that my aged system was needing to be replaced yesterday. When it is time to replace our system I know who to call now. You are doing yourself a disservice if you do not use Degree Heating and cooling for your HVAC needs.”
SQUARE ONE HEATING & COOLING LLC
Heating & Air Conditioning Contractors in Crystal Lake, IL
Average rating: 5 out of 5 stars23 June 2016
“Square One Heating and Cooling fixed my air conditioner. I was told by another local heating and air conditioning business that I needed a whole new air conditioning unit for around $5000. Square One repaired the air conditioner by installing a new fan motor for a fraction of the cost of a new unit. Square one's workers were knowledgeable, professional and fit me into there schedule quickly. I would highly recommend them.”
