This place did solid work at our home doing some venting for a heater, and when we hit an issue with quoted versus billed labor cost, the owner didn't hesitate to make it right. Highly recommended.

I absolutely love this company, we have very unique homes out here and H&M has always delivered great quality service. They help us turn our swamp coolers on and off each season, and it's been a great company for our units. Services: A/C system maintenance, HVAC system maintenance

On the hottest day of the year we're very pleased with the professional check-up that Joe performed on our AC system; particularly the thorough inspection and maintenance of the outdoor condenser unit. Terrific workmanship and customer service at a very reasonable price! Service: A/C system maintenance

H&M Mechanical is the best in the area for heating, air conditioning, and refrigeration. They are locally owned and have a stellar reputation. On time, super professional, and a good value for your money, you don't need to worry when working with this team. Recently Jesse Coleman and Joe Hashman installed a new furnace in our home. They were outstanding and it was a massive job. They were responsive, fast, and installed a new highly efficient thermostat. I would highly recommend this company.

I have been using H&M for the last twenty years for my home and rental properties. Their technicians are always professions and do a great job at a fair price. They have excellent emergency response. When my water heater broke one night, they arrived the next day to install a new one, quickly and efficiently.

Tony and Joe arrived right on time and stayed until they knew the furnace was working just right. They didn't stop for lunch and they did a great job. They answered all my questions and made sure I knew everything I needed to know about running the furnace before they left. They cleaned up really well prior to leaving and attended to all COVID rules while in my house. All in all they worked from 8-8. I couldn't have been happier with the outcome.

We have used H&M for a number of years. Our service yesterday was amazing! Connor spent a great amount of time and care with our equipment. He is friendly, knowledgeable and very thorough. We appreciated his attention to detail with every single item. We are so grateful for H&M. Technicians like him are the reason our equipment has run so well for so many years. Thank you!

Connor came out within an hour of me calling H&M about our old, broken water heater, and not only was he able to get us a replacement tank at a good price, he installed it the very same day as well. It was a great experience, he really knows what he's doing, he was very efficient and also very friendly and professional. I would recommend H&M Mechanical to anyone who needs a hot water tank replaced.
