Hinrichsen Heating & Air Conditioning, Inc. holds a 4.8-star rating across 18 Google reviews. The reviews below are shown word-for-word as customers wrote them on Google — same-day AC and furnace fixes, one-day replacements, 2 a.m. emergency calls answered, and geothermal parts on the truck when other companies quoted weeks.
- AC & Installs
“Complete AC replacement in 1 day. Great service.”
- General
“Awesome crew and owner is very wonderful!!! Great prices! Quick response! All around the greatest hvac company around!”
- Geothermal
“They had a fan for my geothermal system on hand, and got out heat fixed last year before it turned cold. Another company had been said it would take weeks to get the part in. Thank you for the quick response and work!”
- Furnace & Heating
“Very thankful for our experience with Hinrichsen! Very responsive and informative. We woke up to a cold house on a Friday and were back in business by the afternoon. We were really hoping we wouldn’t have to go into the weekend without our furnace able to keep up. Technician Ray did a great job…”
- AC & Installs
“Just installed a new AC and furnace. Quick, professional, significantly more cost effective that other places I got quotes from”
- Furnace & Heating
“Called Hinrichson on Tuesday and they had a tech at my house the next day! Fixed my issue!!”
- Emergency Service
“Furnace went down, made multiple 2am calls. They responded in a timely manner, professional, and they were able to provide the exact services needed to get me up and running. Doug was the only name I heard or remember lol so he gets the credit!”
- Furnace & Heating
“They provided excellent, quick service on our furnace at a fair price once again.”
- General
“…Hand down the best heating and air place in the area. They have been servicing my house for 25+ years”
What should you take away from these reviews?
Three patterns, and they're the ones that matter when you're choosing an HVAC company: speed when it counts (2 a.m. emergency calls answered, same-day furnace and AC fixes, next-day appointments), straight pricing (multiple reviewers comparing us favorably against other quotes), and depth on geothermal — including having WaterFurnace parts on hand that other companies quoted weeks to order. That last one is no accident: we've installed more than 1,000 geothermal units here since 1987.
