Best Heating & Air Conditioning / HVAC In Buffalo Grove

“They're very knowledgeable and reliable of the HVAC system and doing their best to get the project done. Highly recommended.“

“This is our second furnace from GV’s and we are happy with everything from the quote to the installation. We recommend them highly.“

“The technician did very good, checking our central air, cleaning and checked the furnace. Well done!!!“

“We've had our fair share of HVAC issues. Igor is, by far, the most thorough and detail-oriented tech that we've worked with. Would definitely recommend!“

“They were amazing helping us deal with our flooded basement. They were there immediately to help dry it out and then worked closely with us during the insurance process. They were understanding and kind, really went above and beyond. We were 100% satisfied and would highly recommend!“

“I honestly cannot say enough good things about Assurance Heating and Air Conditioning. We were stuck in the middle of a record-breaking heat wave and our AC went out, but they came out incredibly fast. Their communication from start to finish was amazing. The best part? They installed a brand new AC unit for $8,000 less than what Four Seasons quoted me for the exact same work. That is a massive difference. If you need HVAC work done, do yourself a huge favor and call these guys first. They completely saved the day!“
