From our location in Maplewood, just south of Kohlman Lake and east of Gervais Lake, we help local businesses stay comfortable, safe, and fully operational year round. At Altemp Mechanical, we provide full service commercial HVAC, refrigeration, and appliance support for companies across the Twin Cities. Since 1994, we have built our reputation by doing things the right way, showing up on time, solving problems quickly, and standing behind our work. Whether you need help with heating, cooling, refrigeration, or commercial kitchen equipment, you can count on one experienced team to handle it all with confidence and care.
At Altemp Mechanical, we install, maintain, repair, and replace heating and cooling systems, refrigeration units, and commercial appliances like coolers, freezers, ice makers, and kitchen equipment. We work with all major brands, so you never have to juggle multiple vendors or wonder who to call. Our factory trained technicians use advanced tools to quickly find the root of the problem and fix it the right way the first time. We understand how important your equipment is to your business, and we work efficiently to reduce downtime and keep everything running smoothly. Our goal is simple. We want your systems to work when you need them, without surprises or delays, so you can focus on your business instead of worrying about equipment failures.
Running a business in Maplewood means dealing with extreme weather that puts real stress on your HVAC systems. Winters are long, cold, and demanding, with temperatures often dropping well below freezing. Your heating system has to work hard for months at a time, which can lead to wear, higher energy use, and potential breakdowns if not properly maintained. Snow and ice can block outdoor units and reduce performance, while strong winds increase heat loss and make your system work even harder. In the summer, the challenge shifts to heat and humidity. Even moderate temperatures can feel uncomfortable when humidity rises, forcing your cooling system to do more work to keep indoor spaces comfortable. Moisture can also impact system performance and air quality if not addressed. On top of that, spring and fall bring constant temperature swings, which cause systems to cycle more often and wear down faster. We design, service, and maintain systems with these exact conditions in mind, helping your equipment perform better and last longer no matter what the season brings.
When your system fails, you need help right away. That is why we offer 24 hour emergency service with fast response times. We know that HVAC and refrigeration issues can quickly create unsafe conditions for staff and customers, damage inventory, or shut down operations. When you call us, we act quickly to diagnose the problem and get your system back up and running. Our team comes prepared with the tools and experience needed to solve issues on the spot whenever possible. We focus on clear communication so you always know what is happening and what to expect next. With Altemp Mechanical, you are never left waiting or guessing. You have a dependable partner ready to step in and fix the problem when it matters most.
The best way to avoid costly breakdowns is to stay ahead of them. We offer preventative maintenance services that help extend the life of your equipment, improve efficiency, and reduce unexpected repairs. Regular service keeps your systems clean, properly adjusted, and running at peak performance. This not only lowers your energy costs but also helps you avoid major issues that can disrupt your business. Our technicians take the time to inspect your equipment carefully and identify small concerns before they turn into bigger problems. After every visit, we provide a clear written service report so you understand exactly what was done and what to watch for moving forward. With the right maintenance plan in place, you can feel confident knowing your systems are reliable and built to handle the demands of Minnesota’s climate.
Altemp Mechanical has been family owned and operated since 1994, and we take pride in delivering prompt, courteous, and dependable service every day. We stand behind our work with a full one year labor warranty, which is far stronger than the short warranties many competitors offer. We also use a real time, paperless tracking system so you can stay updated on your service as it happens. If something does not meet your expectations, we will return and make it right. Our team is built on people who care about doing quality work and treating customers with respect. From the first call to the final repair, we focus on making your experience simple, clear, and stress free. When you work with Altemp Mechanical, you are choosing a partner who is committed to keeping your business running strong across Maplewood and the entire Twin Cities area.
