Heinanen Engineering, Inc. (HEI) delivers the latest in heating, cooling, and energy conservation to commercial and residential customers across southeastern Michigan. In business since 2002, Heinanen treats every customer as important and significant, whether the job is a simple hot water heater replacement or an entirely new commercial HVAC installation.

HEI features reliable and energy-efficient Trane products. HEI services include furnace repair or replacement, air conditioners, modern gas-burning fireplaces, and heat pumps that provide an alternative, energy efficient way to heat and cool your home in the spring and fall months. HEI-installed water heaters provide the perfect balance of comfort and efficiency. If you don’t want to be left in the dark when the power goes out, let HEI install a generator for you.

If you’re looking for a simple way to reduce energy bills, HEI can install a Trane programmable thermostat in your home or business. Estimates suggest a typical family can save about $180 every year by employing this inexpensive technology.

If air quality is a concern of yours, HEI can come to the rescue with air cleaners, UV lights that can kill up to 87% of bacteria passing through your heating/cooling system, or a whole-house humidifier that can transform the comfort of your home by adding moisture to the air during dry winter months.

For big purchases, HEI offers financing through Trane financial services as well as through the Michigan Saves home energy loan program. HEI services are available 24 hours a day, 7 days a week, every day of the year.
