Air Conditioners

When selecting an air conditioner for your home, you have an array of choices. When sliced bread was invented in 1912, it was the greatest thing to happen since air conditioning. You see, our founder, Willis Carrier, invented the first modern air conditioning system in 1902. And we’ve been perfecting his idea ever since while enjoying the occasional piece of toast. Ask your Carrier® expert about current energy efficiency standards to ensure your new air conditioner meets government regulations for your area.


The furnace is the heart of your home—out of sight, out of mind, and still keeping you and your family comfortable all year round. Our quiet, energy-efficient furnaces are designed to provide warmth to keep you cozy in winter and to circulate clean, refreshing air from your cooling system in the summer.

Fan Coil Units

A fan coil is an indoor unit of a heating and cooling system. It controls your home environment by moving air inside your home and can also affect your indoor humidity. As a complement to your air conditioner or heat pump, our variable-speed fan coil units can give you premium comfort and energy-saving performance.With an optional electric heat strip, a fan coil can also provide heat to your home if you live in milder climates.

Ductless Mini Splits

Ductless mini splits, including ductless air conditioners and ductless heat pumps, can fit in any space, even where traditional HVAC units don’t. With their virtually endless configurations, ductless air conditioner and heat pump products deliver comfort with minimal visual impact. Ductless heating and cooling systems are different from traditional split systems because they come in all shapes and sizes, and don’t require ducts inside your walls. These wall mounted air handlers are flexible and work wherever you need them.

Residential Boilers

Recent upgrades keep KNIGHT at the head of the class, allowing it to continue to lead the charge as the industry-leading high-efficiency residential boiler. Available in 13 models and more adjustable parameters than any other competitor, KNIGHT is the most flexible residential boiler you can install.

Evaporator Coils

Evaporator coils are the unsung heroes of an air conditioning or heat pump system. These units are found on top or below your furnace, and help complete your system by transferring heat for enhanced home comfort. Your Carrier expert will recommend the appropriate sized coil for your system, so that your equipment can operate at maximum efficiency.

Geothermal Heat Pumps

Geothermal heat pump systems tap into the energy right in your own backyard—transferring heat to or from the earth to heat or cool your home. No matter what the weather is like outside, geothermal heat pumps deliver energy-efficient performance to give you the most comfortable indoor comfort for your home.

Packaged Products: Combined Heating & Cooling Systems

Our packaged HVAC systems are designed to make it easy for you to have whole-home heating and cooling. We’ve combined multiple components into a single unit that sits outside your home to deliver the comfort you’re looking for—heat in the winter and cooling in the summer.

Indoor Air Quality

Air impurities, excessive moisture or dryness and poor ventilation can compromise indoor air quality. Carrier® air quality products offer solutions that can help affect the indoor air contaminants that can afflict your home. Ask your Carrier HVAC dealer to run an indoor quality test to determine which products they recommend to help alleviate indoor air problems.


At Doty Mechanical, we understand the importance of keeping your home safe, comfortable, and fully operational, even when the elements have other plans. That’s why we’re thrilled to introduce our top-of-the-line Whole Home Generators – your ultimate solution for uninterrupted power supply during those unexpected Michigan storms.

UDX Unit Heaters

A great way to keep your garage or warehouse heated. Reznor® model UDX gas-fired unit heaters are an excellent solution space heating applications. These units are power vented to eliminate heat losses up the flue pipe. Model UDX is available in 14 sizes ranging from 30,000 to 400,000 BTUH gas input and are approved for installation in the United States and Canada by ETL.

Heat Pumps

A heat pump is a heating and cooling system used to transfer heat from one location to another, typically between an indoor and an outdoor environment. It operates based on the principle of moving heat rather than generating it through combustion, making it an energy-efficient and environmentally friendly heating and cooling solution.
