All reviews for Hemmelgarn Heating and Cooling Services

Phenomenal response time. Great price. Honest. Showed me exactly what was wrong and what I needed. Had it fixed in no time. Couldn't be happier.

Had a gas leak issue and Marty was quick to come out and quick to fix the issue. Very effective and efficient!

With the recent heat, we fired up the A/C which wasn't cooling the house down. Texted Marty the next morning and he squeezed me in that afternoon. Always thorough with his work and will take the time to explain things to you...highly recommend!

Marty and his team came and fixed my old HVAC on short notice. Dependable and honest, highly recommended.

Marty installed a mini-split system for us and did an incredible job! Very thourough and quick install. I would recommend him to anyone needing reliable HVAC services in Columbus!

Marty is the best! We’ve had a few HVAC people in the past service our house and no one comes close to how good Marty and his team are. They’re always on time, dependable and honest.

Marty is the best! He's always communicative and shows up when he says he will. Marty and his team have installed a water heater and sump pump for us, and came over on short notice to check our furnace. Highly recommend Marty and his team

Another excellent job by Marty! Always makes sure he gets the job done right for a reasonable cost. When he leaves the job he leaves the work area in excellent condition which frankly is quite rare anymore. He takes pride in his work and is very knowledgeable. If I need any heating, cooling, or water heater needs, my first call.always!

Marty was fantastic—honest, knowledgeable, professional, and very reasonable with pricing. Another bigger company told me I needed a full system replacement for $14,000 or repairs ranging from $2,500 (best case) to $4,700 (worst case), with no cheaper options. Marty came out, carefully checked everything, and recommended using a leak sealant instead—exactly what I was hoping for. The total cost was less than a third of the $2,500 estimate from the 1st bigger company, and the AC is working great now. On top of that, he charged $100 less per pound for Freon compared to the first company. I highly recommend Marty if you want honest advice and quality service without the upsell!

Would give them 10 stars if I could! BEST IN THE BIZ right here. Marty did excellent work on our older furnace - Got us up and running in no time. Thank you!!
