Approved Comfort heating and air conditioning installed my furnace in one day and I got the best value I could have gotten. I have been doing business with them for over 6 years, and every time someone comes to my home to repaire or install my furnace and or air conditioner, I am treated like a new customer. The office is always professional and courteous, just like the service technicians and even the salesman Dave. The sales aspect was educational and it appeared to be over promised, but to my surprise from the drop cloths on the carpet, to the thank you hand shake at the end, I was under promised and over delivered when it came to my furnace installation. Living in the Boulder Ridge subdivision in Lake in the Hills, I am always sceptical to businesses that want to raise their prices just because of where I live. Approved Comfort Heating and Air Conditioning was priced right. Thank you guys and gals, I will see you for my annual maintenance next year.
