Get matched with top air conditioning pros in Keego Harbor, MI

"I contacted Greg after I turned on the heater for the first time and noticed a burning smell coming from the ducts. While they were booked out three days in the future, Greg found a way to work us into the schedule the same day. Within hours, they had the problem diagnosed and had located the parts needed to fix it--all at a fair and reasonable cost. Additionally, they offered advice on how best to maintain our air conditioning unit. I would highly recommend them and will be calling them again with future work."

"See above. I was very nearly cheated out of $3600 to replace an air conditioning unit that wasn't even broken."

"Very responsive to critical need to fix air conditioning during the heat wave. Courteous, friendly and professional. I highly recommend Harriman."

"I hired midpoint cool temp to install furnace & air conditioner, the price was negotiable, fast service clean area , I will recommend family and friends"

"Zack came in to give me quote as was the only guy who was not a sales person. Value for money wise his company is excellent. He installed Tempstar furnace and Media filter. We pulled the permit . The mechanical inspector came in and said whoever did this job did it professional. Particularly he liked how the media filter cabinet was installed. We couldn't get the CWire to the thermostat. He will be coming in this week to install it. Every electrical connection were clamped to the duct properly. He also put in new drain for the humidifier. Awesome guy. Normally I would wait for atleast 6 months to a year to leave a review. In this case, because of the exceptional installation and because of the comment that inspector made i am leaving 5 star review. Will update in future if any new issues crop up. I don't expect that to be case."

"Excellent rates for cleaning both air conditioning and furnace. Prompt service, with excellent response times. Staff were knowledgeable, helpful, and professional."

"This company went above and beyond. From the estimate to the install of both a new furnace and air conditioning unit quickly after the estimate. We had been without heat for 4 days in December in Michigan. Glad to sleep in a home with heat again."

"They are the most thorough ac and heating guys in 26 years. The price is right and they care about their work."
