“Had my furnace go out suddenly this week during cold weather. I called early in the day and spoke with Staff who indicated they would do what they could that day. Sure enough, I received a swift callback from Field Tech Bruce who arrived promptly.”
“Bruce came to clean the pilot light on our water heater, but also gave us extremely helpful information about why our light was going out. Then, when our heater went out, on a Sunday no less, Hansen was our first call and they were incredible about providing information up front about the increased cost of coming out on a Sunday.”

“I had used AM at my other home with no problems so when I moved to a newly constructed 2 bedroom 1 bath fully carpeted basement apartment in my son's home I called them about the possibility of a dehumidifier on the brand new furnace. They assigned Rep 1 and after blowing me off twice without calls or explanations and when came out and then lied to me about why he didn't show. I knew this because the receptionist I …”
“Completely lazy customer service, with mixed/improper expectations. Called for 3 days, each day told would be serviced later that day. Each day, no call, no show. Excuses each time pointing to bad to be management and disorganization. On the 4th day (today) , was told someone came out the prior evening but no one was home. I was home all day/evening and was awaiting the pre-call that I was told repeatedly that I'd …”

Even told them the exact part (inducer fan) that needed to be fixed or replaced. Not to just service my furnace and run a bunch of pointless tests take my money and leave, which is all they did. They lied to me and said anything can be wrong with an inducer fan so they don't know where …”
